Dr. Hank Liers, PhD immune charge+ liposomal shot formula

Recently our friends at Quicksilver Scientific introduced a therapeutic “shot” formula called IMMUNE CHARGE+™. This unique product takes immune support to the next level. It is a potent, high-dose liposomal blend of foundational vitamins C, A, D, E, K1, K2, and Haschberg European black elderberry — all delivered in a single 12 ml (0.4 ounce) shot that supports your body’s first-line defenses against unexpected health challenges.

I am highly impressed with IMMUNE CHARGE+ shot formula. Most people, including myself, feel its effects almost instantly after taking a shot and holding it for 30 seconds in the mouth before swallowing it. This is due to the 1) amazing properties of liposomal delivery and 2) therapeutic levels of key ingredients.

If you’re looking for an immune boost that will take you through your day, I can’t think of a better product. Even if you’re already supporting yourself with supplements, I recommend IMMUNE CHARGE+ for those times when you need an extra boost to your immune system.

IMMUNE CHARGE+ supports respiratory health and function, powers healthy inflammatory response to unwanted invaders, and has unsurpassed bioavailability of both premium elderberry (without the sugar load in typical extract) and known immune-support vitamins.

immune charge+ shot liposomal formula


IMMUNE CHARGE+ is an intentional mix of six bioavailable vitamins that work synergistically to promote respiratory strength, cellular integrity, and year-round resiliency. Combined with Haschberg European elderberry, known for its immune system benefits — finally in a form your body can use — the result is a powerful liposomal “shot” for immune defenses.

• Activates a robust immune response
• Boosts white blood cell production
• Protects against respiratory pathogens
• Enhances barrier integrity of lung, gut and skin epithelial cells
• Supports cellular integrity
• Quenches excessive pathogen induced inflammation
• Optimizes cellular redox state to enhance defense against pathogens
• Reduces cold duration and symptoms

One shot of IMMUNE CHARGE+ contains: Liposomal Vitamins C (2,000 mg), Vitamin D3 (10,000 IU), Vitamin A (7,500 mcg; 25,000 IU as palmitate), Vitamin E (40 mg Delta Gold Tocotrienols), Vitamins K1 & K2 (1,050 mcg), and Haschberg Elderberry Extract (200 mg) (ElderCraft®)†. Other ingredients include: water, glycerin, ethanol, phospholipids (from sunflower lecithin), Vitamin E (as tocofersolan), citric acid, and natural citrus oils).


IMMUNE CHARGE+ supercharges the immune system.  It is in a class by itself when compared with other immune support formulas—offering rapid liposomal delivery—and thereby unparalleled bioavailability of its immune-bolstering ingredients. In addition to kicking off a robust immune response and up-regulating white blood cell production, Immune Charge+ formula protects cells from pathogen-induced harm and attenuates excessive inflammation.

Health Products Distributors, Inc. normally sells IMMUNE CHARGE+ in cases of 12 shots, but for a limited time we are selling it in smaller amounts (as little as one bottle) so customers like you can experience these powerful effects! Order a bottle or two (or more), and see how effectively it works for you.

Vitamin C (ascorbic acid) offers multifaceted support to the immune system, supporting cellular integrity, antioxidant status, and respiratory function during viral infection.

The epithelial cells of the skin, lungs, and gastrointestinal tract serve as a first-line of defense against microbial invaders, including viruses responsible for respiratory infections such as colds and the flu. Vitamin C supports epithelial barrier integrity, enhancing the function of these fundamental defense systems.

Vitamin C is a potent reducing agent, meaning it readily donates electrons to electron-deficient recipient molecules (also referred to as free radicals), stabilizing their biochemical structure and inhibiting a chain reaction of oxidative stress. Vitamin C’s ability to terminate these harmful chain reactions makes it one of the body’s most crucial antioxidants. In fact, vitamin C is the body’s primary non-enzymatic, water- soluble antioxidant in blood plasma and tissues. The potent antioxidant properties of vitamin C make it a valuable ally for optimal immune function.

Bacterial and viral infections trigger the production of free radicals by immune cells. While these free radicals have an essential purpose — to activate the innate immune response and directly destroy invading pathogens such as RNA viruses — they also have the unintended consequence of damaging our own cells and organs, such as the lungs.Vitamin C attenuates pathogen-induced free radical damage, protecting cells from harm while the immune system is hard at work eradicating infection.

Vitamin C also boosts the activity of other antioxidants vital to the immune system. It recycles the fat-soluble antioxidant Vitamin E and increases endogenous levels of glutathione, the body’s premier antioxidant that also fine-tunes the innate immune response to viral infections.

Respiratory Health
Vitamin C also protects the lungs during severe respiratory infections. Vitamin C increases the resistance of chicken tracheal cells to infection with the avian coronavirus. It also shortens the duration of convalescence from bacterial pneumonia, a common consequence of severe viral respiratory infections.

Inhibits Virus-Induced Inflammation
Viruses activate the NLRP3 inflammasome, a multiprotein complex that plays a crucial role in innate immunity and the production of pro-inflammatory cytokines. Excessive NLRP3 activation contributes to a phenomenon called a “cytokine storm,” an overproduction of immune cells and their activating products, cytokines. Cytokine storms occur in the end stages of severe infections, causing symptoms such as acute lung inflammation and fluid buildup in the lungs. The cytokine storm can thus severely sicken, and sometimes kill, patients. Attenuation of NLRP3 inflammasome activity may inhibit excessive inflammation in viral infections. Vitamin C inhibits the NLRP3 inflammasome and may thus help inhibit virus-induced inflammation.

Emerging research suggests that intravenous Vitamin C is useful for the treatment of severe viral infections. Unfortunately, vitamin C IVs may not be accessible to many infected patients. Liposomal vitamin C has been found to offer a greater degree of bioavailability as intravenous (IV) vitamin C in a more convenient and less invasive delivery system.

Antiviral Immune Response
Finally, vitamin C is an essential factor in the antiviral immune response to viral respiratory infections, such as influenza H3N1, through increased production of interferon-α/β. It also stimulates phagocytosis, neutrophil chemotaxis, and T-cell development and maturation, crucial processes for fighting pathogenic bacteria and viruses.


Vitamin A maintains epithelial barriers in the human body, including the epithelial lining of the lungs and the gut mucosa, where a significant portion of the immune system resides. Vitamin A deficiency compromises immunity in the lungs, rendering them more susceptible to respiratory infections. Vitamin A deficiency also impairs the immune response to intranasal vaccination for respiratory syncytial virus (RSV), a human virus that causes respiratory infections, thus suggesting that this nutrient is crucial for the development of the host immune response to envelope viruses. Altered Vitamin A metabolism is also suspected to play a role in the pathogenesis of influenza.

Conversely, Vitamin A sufficiency, and supplementation reduce susceptibility and mortality in numerous preclinical and clinical models of viral infection. In preclinical research, animals fed Vitamin A-deficient diets suffer from more severe coronavirus infections than those fed vitamin A-sufficient diets. High-dose supplemental vitamin A also enhances the immunoglobulin response to influenza A virus.

Finally, Vitamin A supports immune homeostasis by activating immune cells when they are needed to combat infectious threats while attenuating excessive inflammation.


Vitamin D has pleiotropic benefits for immunity. Vitamin D receptors (VDR) are present on most immune cells, indicating their indispensability as components of the immune system.24 Vitamin D deficiency has repeatedly been independently associated with an increased risk of viral infections.

Vitamin D modulates both the innate and adaptive immune responses to respiratory viruses. In the presence of viral infection, lung epithelial cells convert inactive vitamin D into the active form, increasing the expression of a peptide called cathelicidin, which has antiviral effects. Vitamin D also modulates the immune response to respiratory viruses and protects the lungs from damage caused by pro-inflammatory LPS.


Vitamin E is a fat-soluble antioxidant that protects the polyunsaturated fatty acids in cell membranes from oxidative damage, which can be triggered by microbial infections. It increases white blood cell proliferation, immunoglobulin levels, natural killer cell activity, and antibody activity, thus supporting broad-spectrum immune function. In our formula, we use a special form of Vtamin E called DeltaGOLD® tocotrienols, which offer fifty times the antioxidant activity of tocopherols, the form of Vitamin E used in most competitors supplements.


Vitamins K1 and K1 are fat-soluble vitamins that work in synergy with Vitamins A, D, and E to support healthy immune function. Vitamin K1 (phylloquinone) has anti-inflammatory properties through inhibition of the NF-κB pathway. Vitamin K2 modulates the immune system, decreasing immune reactivity and helping to manage the inflammatory response.


Elderberry is a small dark purple berry that has been used for centuries in traditional herbalism as an aid to the immune system. In this formula, we use Haschberg variety European black elderberry, known for its high potency in anthocyanin flavonoids.

Modern herbalists know that elderberry’s high-concentration anthocyanin flavonoids have vast potential to kickstart immunity, especially upper respiratory function. In this one-of-a-kind, highly bioavailable formulation, we’ve combined it with proven immunity supporting Vitamins A and C — without the added sugar normally found in elderberry products.

When unwanted invaders irritate the immune system and turn up inflammation, other star performers Vitamins A and D work with elderberry to strengthen and fortify your body by helping to balance inflammatory and immune responses. Highly bioavailable Vitamin E kicks in with 50 times the antioxidant activity of typical tocopherols, alongside Vitamins K1 and K2, which help manage the body’s positive inflammatory response.


Elderberry has direct antiviral activities, demonstrating mild inhibitory effect at the early stage of viral infection and a considerably stronger response in the later stages of infection.Elderberry exerts antiviral effects by blocking the function of hemagglutinin (HA) glycoproteins present on the surface of viruses, such as the influenza virus and coronaviruses. When the binding of these spikes to host cells is inhibited, viruses cannot enter the host cell to replicate and cause infection. Elderberry also binds to neuraminidase (NA), an enzyme necessary for viral replication, as indicated by mass spectrometry and molecular docking studies.

The ability of Elderberry to target viruses through multiple pathways may make it unlikely to trigger antiviral resistance, a common problem with antiviral pharmaceutical drugs. Given these findings, it is no surprise that a meta-analysis of RCTs found elderberry supplementation effective for the treatment of upper respiratory symptoms, which are frequently caused by viruses. In fact, one study found that overseas travelers using elderberry for 10 days before traveling and up to five days after arriving experienced a two-day shorter duration of the cold (on average), along with noticing a reduction in symptom severity.

Elderberry’s antimicrobial activity is not limited to its effects on viruses. It also inhibits the growth of clinically relevant bacteria that can cause infections, such as pneumonia that are secondary to infection with a respiratory virus.


Elderberry is an immune modulator, enabling a robust immune response while inhibiting excessive inflammation. Elderberry also coordinates a more efficient immune response by mobilizing antiviral innate immune defenses, including the release of the cytokines IL-6 and IL-8. The antioxidant anthocyanins found in elderberry may quench excessive inflammation triggered by a viral infection and promote the growth of beneficial gut bacteria, many of which have immune-enhancing properties.


Finally, Elderberry also fine-tunes the cellular redox state, or the balance between reactive oxygen species (ROS), reactive nitrogen species (RNS), and their scavenging by antioxidant compounds. The cellular redox state plays a critical role in the immune defense against viral invaders. When ROS and RNS accumulate in viral infections and antioxidant systems are depleted, a severe inflammatory response called a “cytokine storm” can occur. The cytokine storm incites a massive release of inflammatory mediators called cytokines that damage vital tissues such as the heart and lungs. Elderberry phytochemicals called anthocyanins boost the cellular redox potential, enhancing cellular resilience against pathogens.

Dr. Hank Liers, PhD antioxidant formulasI have written extensively regarding the benefits HPDI’s PRO-C™ and Ultimate Protector™ antioxidant formulas. Based upon my experience with these formulas they are among the most effective antioxidant formulas available.

Both antioxidant formulas are included in HPDI’s system of foundational supplements and work most effectively when used with multivitamins, essential fats, and superfoods.

Yet, both formulas also are excellent standalone products that can rapidly provide the body with extremely high protection against free radicals.
Ultimate Protector antioxidant formulas

We are often asked “which of these two antioxidant formulas should I take?” My answer usually is to take both formulas. I personally take both of them on a daily basis.

Below I will briefly show the reason my answer is to take both formulas. I include information showing the relationship, in terms of ingredients of the two formulas (per serving of three (3) capsules daily of PRO-C and six (6) capsules daily of Ultimate Protector).

Ultimate Protector


PRO-C™ (per serving of three “00” veggie caps)

• Buffered non-GMO Vitamin C (1,500 mg)  buffered with Ca/Mg/Zn
• Grape Extract (seed, skin, and pulp) (90 mg)
• Green Tea Extract 95% polyphenols 40% min. EGCG (90 mg)
• Glutathione – reduced (60 mg)
• N-Acetyl-l-Cysteine (NAC) (45 mg)
• R-Lipoic Acid (15 mg)
• Coenzyme B2/R5P (3 mg)
• Coenzyme B6/P5P (3 mg)
• Selenium from l-selenomethionine (30 mcg)
• Calcium (70 mg)
• Magnesium (70 mg)
• Zinc (6 mg)

ULTIMATE PROTECTOR™ (per serving of six “0” veggie caps)

• Vitamin C as non-GMO Ascorbic acid (1500 mg)
• Anthocomplete™ (135 mg)  Wild Blueberry, Wild Bilberry, Acai, Black Currant Extract, Sweet Cherry, Raspberry, Elderberry, Blackberry, Aronia, Black Soybean Hull Extract, and Blue Corn
• CoffeeBerry®Forte (135 mg)
• Vitaberry® Plus (90 mg) freeze-dried Grape Seed, Wild Blueberry, Wild Bilberry, Cranberry, Tart Cherry, Prune, Raspberry Seed, Strawberry, Trans-Resveratrol, and Quercetin
• VitaVeggie® (90 mg)  Broccoli, Broccoli Sprouts, Tomato, Kale, Carrot, Brussels Sprouts, Onion, and Spinach
• Curcumin 95%  (90 mg)
• Trans-Resveratrol 98% (90 mg)
• Malic Acid (500 mg)
• Calcium (60 mg)
• Magnesium (60 mg)
• BioPerine® (7.5 mg)

The products together contain nine (9) unique PRO-C™ ingredients, eight (8) unique Ultimate Protector™ ingredients, and three (3) overlapping ingredients.



When PRO-C™ was first released in 1997 there were few publications available regarding Nrf2 ingredients and their benefits. The product design was based on the work of Dr. Lester Packer and his work done on the “Antioxidant Network” showing how nutrients such as Vitamin E, Vitamin C, Glutathione, and Lipoic acid work in a redox network to regenerate key nutrients in the body (see Figure 1. below)

doctor lester packer antioxidant formulas

                                                Figure 1. – Dr. Packer’s Antioxidant Network

At that time the powerful antioxidant formulas of Grape Seed Extract and Green Tea Extract were well known, but their powerful Nrf2 effects were not discovered until later. These ingredients are able to trap free radicals and conserve the body’s store of network antioxidants.

Also, the Nrf2 effects of NAC and Lipoic acid were not known at the time, but their powerful effects on the body were known to support the production of glutathione. Additionally, the super powerful glutathione (reduced) was included with supporting coenzymes B2 (from riboflavin 5′-phosphate) and B6 (from pyridoxal 5′-phosphate) that allow the enzymes glutathione reductase and transferase to function at a higher level.


From the beginning of the design process, Ultimate Protector™ (UP) was focused on creating a highly effective Nrf2 activator formula with outstanding antioxidant effects. Our understanding was that a very broad spectrum of plant polyphenols including flavonoids, anthocyandins, oligoproanthocyanidins (OPCs), etc. would deliver the best results.

We selected Futureceuticals Anthocomplete™, CoffeeBerry® Forte, Vitaberry® Plus, and VitaVeggie® in order to accomplish this and added Curcumin 95%, and Trans-Resveratrol 98% because of the powerful scientific findings regarding Nrf2 activation for these two ingredients. We found out later in testing that this combination of ingredients produces very high ORAC5.0 values (486,000 units/serving of six capsules) and works effectively against all of the primary types of free radicals in the body.


Ultimate Protector versus PRO-C antioxidant formulas

Venn diagram showing unique and overlapping ingredients in PRO-C and Ultimate Protector.

There are 29 unique Nrf2 activator ingredients in Ultimate Protector (UP) and four (4) non-overlapping Nrf2 activator ingredients in PRO-C. Thus by taking both formulas you are able to receive 33 identifiable Nrf2 activator ingredients (870 mg). The amount of unique Nrf2 ingredients is probably significantly more than this because most of the identifiable ingredients contain a range of plant polyphenols.

Other unique ingredients of each formula include glutathione – reduced (60 mg), malic acid (500 mcg), zinc (6 mg), selenium (30 mcg), B2 (3 mg) and B6 (3 mg) from coenzyme forms, and Bioperine (7.5 mg) (for enhanced absorption of nutrients). These are important ingredients to have the formulas work more effectively together.

The overlapping ingredients in the formula include Vitamin C (3 gm – 1.5 gm from each formula), calcium (130 mg – 70 mg from PRO-C & 60 mg from UP), magnesium (130 mg – 70 mg from PRO-C & 60 mg from UP), and a little grape seed extract (~10 mg). We view this to be very positive especially because we believe that most people should take in at least 3 grams daily of Vitamin C. Equal amounts of calcium and magnesium balance each other in the body and have many important functions such as being part of critical enzymes.

Dr. Hank Liers, PhD biography about us HPDI integratedhealth formulator founder CEO scientist physicistUltimate Protector contains elderberry (Sambucus nigra), as well as components from 29 different fruits, vegetables, and herbs. Each of these ingredients contain substances that may be considered to be polyphenols, antioxidants and Nrf2 activators. In this article I will explore the ingredient elderberry which is a component of Anthocomplete® from Futureceuticals.


AnthoComplete™ (N669) is a specially designed blend of anthocyanins derived from wild bilberry, wild blueberry, acai, black currant extract, sweet cherry, raspberry, elderberry, blackberry, aronia, black soybean hull extract and blue corn. Anthocyanins are powerful plant polyphenols associated with a variety of areas of human health, including healthy aging, healthy glucose metabolism, cardiovascular health and inflammation management.

Carefully designed to maximize the amount of beneficial anthocyanins that can be available in a single source, AnthoComplete is a proprietary formula suitable for a wide-range of applications.

With its diverse blend, AnthoComplete contains a minimum level of 10% anthocyanins, 3,000 ORAC μmole TE/g (typical), and 15% total phenolics (typical).


Elderberries were listed in the CRC Handbook of Medicinal Herbs as early as 1985, and are listed in the 2000 Mosby’s Nursing Drug reference for colds, flu, yeast infections, nasal and chest congestion, and hay fever. In Israel, Hasassah’s Oncology Lab has determined that elderberry stimulates the body’s immune system and they are treating cancer and AIDS patients with it. The wide range of medical benefits (from flu and colds to debilitating asthma, diabetes, and weight loss) is probably due to the enhancement of each individual’s immune system.

Elderberry Tea

Elderberry makes a great tea, too.

At the Bundesforschungsanstalt research center for food in Karlsruhe, Germany, scientists conducting studies on Elderberry showed that elderberry anthocyanins enhance immune function by boosting the production of cytokines. These unique proteins act as messengers in the immune system to help regulate immune response, thus helping to defend the body against disease. Further research indicated that anthocyanins found in elderberries possess appreciably more antioxidant capacity than either vitamin E or vitamin C.

Studies at Austria’s University of Graz found that elderberry extract reduces oxidation of low-density lipoprotein (LDL) cholesterol. Oxidation of LDL cholesterol is implicated in atherogenesis, thus contributing to cardiovascular disease.

The ORAC value of Elderberries is 14697 micromoles/litre of Trolox equivalents per 100 grams. This is among the highest values for fruits and berries.

 Scientific Studies on the Antioxidant Effects of Elderberries and Anthocyanidins


Polyphenols pattern and correlation with antioxidant activities of berries extracts from four different populations of Sicilian Sambucus nigra L.


Sambucus nigra L. is wide spread in temperate and sub-tropical zones. The consumption of its berries has been associated with health benefits especially for its high content of natural antioxidants such as polyphenols, in particular anthocyanins. In this work we investigated the polyphenolic composition and the in vitro antioxidant activities (ABTS, DPPH, BCB and FRAP-ferrozine (FRAP-FZ) assays) of S. nigra berries, collected in four different Sicilian areas (Italy). Elderberries are considered one of the fruits with highest anthocyanins content, the amount of phenolic compounds, other than anthocyanins, is approximately 1.5 times greater than the latter. The LC-MS analyses have revealed an opposite trend in the polyphenols pattern in Sicilian populations. Moreover, a statistical correlation was found between cyanidin-3-sambubioside-5-glucoside and antioxidant activity evaluated by FRAP-FZ and ABTS assays. In conclusion, Sicilian S. nigra berries are appealing for its antioxidant potential and for its particularly high content of anthocyanins.

Total phenolic, anthocyanin contents and antioxidant capacity of selected elderberry (Sambucuscanadensis L.) accessions.


Fourteen purple-black American elderberry accessions (Sambucus canadensis L.) obtained from various sites in midwestern USA and then grown at a single Ohio production site in USA were analyzed for their total phenolic (TP) and total monomeric anthocyanin (TMA) contents and for their antioxidant capacity by the ferric reducing antioxidant power (FRAP) and DPPH radical scavenging assays. Total phenolic and anthocyanin contents were measured using the Folin-Ciocalteu reagent and the pH differential methods, respectively. Overall, the phytonutrient contents and antioxidant capacity of our elderberry accessions were similar to those typically reported for black raspberries, blackberries and other dark-fleshed small fruits. Variability among accessions was greatest for TMA content (CV 37.5%); individuals ranged nearly threefold from 1308 to 4004 μg cy3-GE/g on a fresh weight basis. Variation among accessions was also evident for TP, FRAP and DPPH values (CV 14.4, 21.7 and 26.8%, respectively). TP and TMA values were very highly correlated (r = 0.93), although individuals differed in the estimated proportion of total phenolics attributable to anthocyanins. Both TP and TMA also highly correlated to antioxidant capacity values (r = 0.70-0.85). Within this limited study of 14 accessions, variability for phytonutrient content and antioxidant capacity suggested the employment of wild germplasm within an elderberry improvement program to incorporate an array of superior horticultural, post-harvest or processing traits into new or existing cultivars with superior phytonutrient profiles.

The effect of Sambucol, a black elderberry-based, natural product, on the production of human cytokines: I. Inflammatory cytokines.


Sambucus nigra L. products – Sambucol – are based on a standardized black elderberry extract. They are natural remedies with antiviral properties, especially against different strains of influenza virus. Sambucol was shown to be effective in vitro against 10 strains of influenza virus. In a double-blind, placebo-controlled, randomized study, Sambucol reduced the duration of flu symptoms to 3-4 days. Convalescent phase serum showed a higher antibody level to influenza virus in the Sambucol group, than in the control group. The present study aimed to assess the effect of Sambucol products on the healthy immune system – namely, its effect on cytokine production. The production of inflammatory cytokines was tested using blood – derived monocytes from 12 healthy human donors. Adherent monocytes were separated from PBL and incubated with different Sambucol preparations i.e., Sambucol Elderberry Extract, Sambucol Black Elderberry Syrup, Sambucol Immune System and Sambucol for Kids. Production of inflammatory cytokines (IL-1 beta, TNF-alpha, IL-6, IL-8) was significantly increased, mostly by the Sambucol Black Elderberry Extract (2-45 fold), as compared to LPS, a known monocyte activator (3.6-10.7 fold). The most striking increase was noted in TNF-alpha production (44.9 fold). We conclude from this study that, in addition to its antiviral properties, Sambucol Elderberry Extract and its formulations activate the healthy immune system by increasing inflammatory cytokine production. Sambucol might therefore be beneficial to the immune system activation and in the inflammatory process in healthy individuals or in patients with various diseases. Sambucol could also have an immunoprotective or immunostimulatory effect when administered to cancer or AIDS patients, in conjunction with chemotherapeutic or other treatments. In view of the increasing popularity of botanical supplements, such studies and investigations in vitro, in vivo and in clinical trials need to be developed.

Characterization of anthocyanins and proanthocyanidins in some cultivars of Ribes, Aronia, and Sambucus and their antioxidant capacity.


Anthocyanins and proanthocyanidins were characterized by HPLC-ESI-MS/MS coupled with a diode array and/or fluorescent detector in seven cultivars of Ribes nigrum (black currant) and Ribes rubrum (red currant, Red Lake), six cultivars of Ribes grossularia (gooseberries), Aronia melanocarpa(chokeberry), and Sambucus nigra (elderberry). Thirty-one different anthocyanins were detected in these berries, but not every anthocyanin was observed in each berry. A number of minor anthocyanins were identified from these berries for the first time. The concentrations of individual anthocyanins in all of the berries were quantified using relevant anthocyanidin 3-glucoside standards. Among the berries studied in this paper and in berries in general, chokeberry has the highest total anthocyanin concentrations [1480 mg/100 g of fresh weight (FW)], whereas the lowest total anthocyanin concentration in the berries studied was found in the gooseberry cv. Careless, which contained only 0.07 mg/100 g of FW. Two cultivars of gooseberries (Marigold and Leveller) did not contain any anthocyanins. Total proanthocyanidin concentrations in the berries studied ranged from 23 to 664 mg/100 g of FW in elderberry and chokeberry, respectively. Procyanidin or prodelphinidin polymers were the predominant components (>65% w/w) in most of the berries. The lipophilic and hydrophilic antioxidant capacities were measured by the oxygen radical absorbance capacity (ORAC(FL)) procedure. The total antioxidant capacity varied from 21 micromol of TE/g of FW in Careless gooseberry to 161 micromol of TE/g of FW in chokeberry. Total phenolics in the berries in general paralleled hydrophilic antioxidant capacity.

Inhibitory activity of a standardized elderberry liquid extract against clinically-relevant human respiratory bacterial pathogens and influenza A and B viruses.



Black elderberries (Sambucus nigra L.) are well known as supportive agents against common cold and influenza. It is further known that bacterial super-infection during an influenza virus (IV) infection can lead to severe pneumonia. We have analyzed a standardized elderberry extract (Rubini, BerryPharma AG) for its antimicrobial and antiviral activity using the microtitre broth micro-dilution assay against three Gram-positive bacteria and one Gram-negative bacteria responsible for infections of the upper respiratory tract, as well as cell culture experiments for two different strains of influenza virus.


The antimicrobial activity of the elderberry extract was determined by bacterial growth experiments in liquid cultures using the extract at concentrations of 5%, 10%, 15% and 20%. The inhibitory effects were determined by plating the bacteria on agar plates. In addition, the inhibitory potential of the extract on the propagation of human pathogenic H5N1-type influenza A virus isolated from a patient and an influenza B virus strain was investigated using MTT and focus assays.


For the first time, it was shown that a standardized elderberry liquid extract possesses antimicrobial activity against both Gram-positive bacteria of Streptococcus pyogenes and group C and G Streptococci, and the Gram-negative bacterium Branhamella catarrhalis in liquid cultures. The liquid extract also displays an inhibitory effect on the propagation of human pathogenic influenza viruses.


Rubini elderberry liquid extract is active against human pathogenic bacteria as well as influenza viruses. The activities shown suggest that additional and alternative approaches to combat infections might be provided by this natural product.

Anthocyanins protect human endothelial cells from mild hyperoxia damage through modulation of Nrf2 pathway.


The detrimental effects of high oxygen supplementation have been widely reported. Conversely, few is known about the effects of exposure to mild hyperoxic conditions, an interesting issue since the use of oxygen-enriched mixture is now increasingly used in clinical practice and especially for professional and recreational reasons. Our study investigated if in vitro exposure of human umbilical vein endothelial cells (HUVECs) to moderate hyperoxia (O2 32 %) induces cellular alterations, measured as changes in cell signaling pathways. Furthermore, by means of an ex vivo experimental model where human volunteers were used as bioreactors, we studied whether anthocyanin metabolites are able to protect HUVECs against mild hyperoxia-induced damage. We observed that the cytotoxic effect of mild hyperoxia came along with a significant decrease in nuclear accumulation of the transcription factor Nrf2, as well as in the expression of Nrf2-regulated antioxidant and cytoprotective genes. Furthermore, under normoxic conditions, anthocyanin metabolites appeared able to activate the Nrf2 pathway, through the involvement of specific kinases (ERK1/2); this adaptive effect may explain the protective effect observed in mild hyperoxia-exposed HUVECs following anthocyanin pretreatment. This study confirms that dietary anthocyanins and/or their metabolites can protect endothelial cells against mild hyperoxia-induced alterations acting as cell signaling modulators.

A comparative evaluation of the anticancer properties of European and American elderberry fruits.

From: http://www.ncbi.nlm.nih.gov/pubmed/17201636


European elderberry (Sambucus nigra), recognized in Europe for its health-promoting properties for many generations, is known to contain a range of anthocyanins, flavonoids, and other polyphenolics that contribute to the high antioxidant capacity of its berries. American elderberry (Sambucus canadensis), on the other hand, has not been cultivated, bred, and promoted as a medicinal plant like its better-characterized European counterpart. In this study, aqueous acetone extracts of the berries from these two species were fractionated and tested in a range of assays that gauge anticarcinogenic potential. Both cultivated S. nigra and wild S. canadensis fruits demonstrated significant chemopreventive potential through strong induction of quinone reductase and inhibition of cyclooxygenase-2, which is indicative of anti-initiation and antipromotion properties, respectively. In addition, fractions of S. canadensis extract showed inhibition of ornithine decarboxylase, an enzyme marker related to the promotion stage of carcinogenesis. Analysis of active fractions using mass spectrometry and liquid chromatography-mass spectrometry revealed, in addition to flavonoids, the presence of more lipophilic compounds such as sesquiterpenes, iridoid monoterpene glycosides, and phytosterols.

Incorporation of the elderberry anthocyanins by endothelial cells increases protection against oxidative stress.

The objective of this study was to investigate the ability of endothelial cells (EC) to incorporate anthocyanins and to examine their potential benefits against various oxidative stressors. Endothelial dysfunction has been proposed to play an important role in the initiation and development of vascular disease, with studies having shown that administration of antioxidants improves endothelial function. Elderberry extract contains 4 anthocyanins, which where incorporated into the plasma membrane and cytosol of EC following 4 h incubation at 1 mg.ml(-1). However, incorporation within the cytosol was considerably less than that in the membrane. Uptake within both regions appeared to be structure dependent, with monoglycoside concentrations higher than that of the diglucosides in both compartments. The enrichment of EC with elderberry anthocyanins conferred significant protective effects in EC against the following oxidative stressors: hydrogen peroxide (H(2)O(2)); 2, 2′-azobis(2-amidinopropane) dihydrochloride (AAPH); and FeSO(4)/ascorbic acid (AA). These results show for the first time that vascular EC can incorporate anthocyanins into the membrane and cytosol, conferring significant protective effects against oxidative insult. These findings may have important implications on preserving EC function and preventing the initiation of EC changes associated with vascular diseases.
