Fred Liers PhD rejuvenate superfoods dietary RNAWhat you don’t know can hurt you. Or perhaps I should say, what you know and implement, can significantly benefit you and your health.

After reading my article, you will have a new knowledge about dietary nucleic acids that can boost your health, improve your well-being, and make your life more vibrant.

If you implement this knowledge, you can live longer, feel better, and experience a higher quality of life. In a word, you will experience ‘rejuvenation.’

So, here are nine important things you may not know about Rejuvenate!™ superfoods and the dietary nucleic acids they are specifically formulated to provide in therapeutic amounts.

Rejuvenate superfoods rejuvenate! RNA nucleic acids


It’s true. Rejuvenate! superfoods help make you look and feel younger. In fact, that’s why we call our line of superfoods “Rejuvenate!™.” Rejuvenate!™ helps you, well, rejuvenate because of all the exceptional ingredients combined into each one of our unique, synergistic formulas. Yet, among the ingredients, dietary nucleic acids stand out as primary therapeutic nutrients which the other ingredients are intended to support in creating health.

How much younger can you look? When discussing this topic with respect to patients he placed on high-RNA diets, pioneer nucleic acid researcher Dr. Benjamin S. Frank states:

“How much younger [my patients] look is, of course, subjective. The older a person, the more dramatically appearance is changed. At 70 or 80 (judging by appearance alone), age seems to regress ten to fifteen years; at 60, about ten years; and at 30 to 50, five years or more.” (No-Aging Diet 6)

What impresses me most about Dr. Frank’s writings on this aspect of dietary nucleic acids is that he understands that changes in appearance are not superficial, but rather relate to the changes made within the body that are reflected in its outer appearance. In this regard, Dr. Frank says, “These changes in appearance are not just skin-deep. From a medical point of view they are not cosmetic at all. They stem from deep-down improvements in health” (6).

In fact, Dr. Frank used what he calls the “pinch test” to determine improvements in skin elasticity. This involves pinching the skin on the back of the hand and using calipers measuring how quickly the skin snaps back into place. He notes that for older individuals it may take three or four months before the skin on the back of the hands and elbows becomes noticeably smoother. However, looking and feeling better can start as soon as one week!

Deep lines and wrinkles grow shallower starting with the forehead, followed by lines around the mouth, and still later by crow’s feet at the corners of the eyes. You can watch this progression occur in yourself or others. When you see it happen, it is nothing short of amazing to witness.

Improvements in how you feel will be just as spectacular, if you give Rejuvenate!™ superfoods and other high-RNA foods a chance to work their “magic,” which isn’t magic at all. It is simply the natural effects of dietary RNA in the human body.


Dietary nucleic acids are essential nutrients. Beneficial dietary nucleic acids include ribonucleic acid (RNA), deoxyribonucleic acid (DNA), as well as nucleotides and nucleosides.

You may not hear about nucleic acids in the popular media, but Dr. Frank considered nucleic acids to be essential nutrients. In Nucleic Acid Nutrition and Therapy (1977), Dr. Frank makes the case for nucleic acids as “essential nutrients of human beings.”

He considers them as distinct from non-essential, accessory nutrients. Dr. Frank thereby asserts that nucleic acids and nucleotides are an essential dietary category. Indeed, he finds these nutrients to be just as essential for human health as vitamins, minerals, proteins, carbohydrates, and fats.

Foods highest in nucleic acids include chlorella, brewer’s yeast, beans, sardines, and organ meats. Chlorella provides ten times the amount found in beans. Not all nucleic acids are the same, however, despite the fact that many of the benefits provided by the nucleic acids in these foods are similar.

Each type of food high in nucleic acids has unique a nucleic acid profile, and provides somewhat different benefits. This means it is best to consume a wide range of dietary nucleic acids, including Rejuvenate! superfoods which are designed to provide the body with multiple types of dietary RNA from different sources.

Rejuvenate!™ superfoods are formulated as plant-based, vegetarian-friendly high-RNA superfoods. They both provide a broad range of dietary nucleic acids and major supporting nutrients to enhance the body’s uptake, assimilation, and usage of nucleic acids. This combination of RNA and synergistic nutrients allows Rejuvenate!™ superfoods to surpass in total nutritional value any single food high in RNA.


Dietary nucleic acids significantly boost energy production in the body. You will feel the difference. Greater energy. More go power. Endurance.

It takes about two to three weeks before the effects of dietary nucleic acid consumption (at therapeutic levels) are fully felt by most people. However, the benefits to health start immediately.

energy jump rejuvenate superfoods

In his books, Dr. Benjamin Frank addresses how nucleic acids can dramatically increase cellular energy. Nucleic acids boost energy levels in the body is by significantly increasing production of the “high-energy” molecule ATP (adenosine triphosphate). The body uses the energy it generates from ATP for many purposes, including all repairing, healing, metabolism, digestion, building a strong immune system, and many other processes.

Dr. Hank Liers formulated Rejuvenate!™ superfoods to leverage all the benefits of dietary nucleic acids. Because all bodily processes from healing to immunity depend upon cellular energy, the fact that RNA boosts energy production (as ATP) in cells means that consuming high levels of dietary nucleic acids gives the body more energy with which to work. This is how dietary RNA supports health and healing.

In fact, Rejuvenate!™ superfoods are one of the four cornerstone supplements in the HPDI system of Foundational Supplements. Other foundational supplements in our system include a high-potency multivitamin, antioxidant and vitamin C formulas, and essential fatty acids.

One of the most surprising benefits of a high-NRA diet is what is known as its “anti-anoxic” effects. In fact, Dr. Frank devotes a chapter in The No-Aging Diet just to the topic of increasing oxygenation of the body, “Eat Better; You’ll Breathe Easier” (48–51).

The amazing thing about this benefit is that Dr. Frank administered nucleic acids to individuals who had obstructive lung diseases, including emphysema and chronic bronchitis. He found that nucleic acids do two things for them: 1) permit the body to make more complete use oxygen that has been breathed into the lungs, and 2) help reduce cough and uncomfortable congestion.

Dr. Frank put these individuals through stair climbing exercises, among other forms of exercise. He reports that a 62-year-old man and former smoker was initially winded going up just a few flights of stairs, and had suffered with weak lungs for five years having forgotten what it was like to breathe normally. After two weeks on nucleic acids and vitamins, he could exercise with less fatigue and gasping for breath.

After six weeks, he could climb two flights of stairs with only mild fatigue, his cough lessened, and his lungs were less congested. The man continued to improve, and after six weeks he was restored to “full vigor” and he felt “dramatically more comfortable” despite the fact that X-rays showed his lungs to be damaged by moderately severe emphysema (49). He returned to his normal work schedule.

Dr. Frank documents other cases like this one, and other cases of individuals suffering from other lung problems. He also treated mice with nucleic acids. He discovered that mice given nucleic acids were able to survive nearly 50% longer under conditions of oxygen deprivation (50–51).

Dr. Frank describes the anti-anoxic effect of dietary nucleic acids as a highly significant effect that permits the body to perform better with less oxygen by making more efficient use of the oxygen consumed by a human or animal.

nucleic acids oxygenation easier breathing rejuvenate superfoods

Nucleic acids help everyone breathe easier. I personally have noticed improved oxygenation and easier breathing. Whereas formerly I would breathe hard during yoga practices, biking, and gym workouts, today I hardly notice any struggle to breathe.

It’s not that I have no need for breathing deeply during exercise. But there is no need for gasping or huffing, and the pace of my breathing is far more even and constant. During yogic pranayama (breathing exercises) I can actually go much longer without taking a breath than I ever could before I began using Rejuvenate!™ superfoods.

Initially, this ease of breathing came as a highly pleasant surprise. Now I simply consume Rejuvenate!™ superfoods (and other forms of dietary RNA) regularly and I exercise without gasping for breath even during the most intense workouts and yoga sessions.


As if all the benefits I’ve already mentioned aren’t enough, here’s another: you can lower your cholesterol levels, easily.

Rejuvenate! superfoods help in this regard because they provide therapeutic levels of dietary RNA. Can it really be that simple? The answer is yes.

For example, Dr. Frank found that for his patients, consuming dietary nucleic acids was more important than low fat diets. In his experience, sardines were the most powerful part of the nucleic acid diet in lowering cholesterol. He found this interesting because sardines aren’t low in fat.

cholesterol reduce control rejuvenate superfoods rna

Of course, we now know that fat consumption alone does not explain high or low cholesterol levels. We also know that certain types of fats can greatly improve lipid profiles. And unlike Dr. Frank (who pioneered dietary nucleic acid therapy in the 1960s and 1970s), we also know that sardines aren’t the only, or the best, form of dietary RNA for everyone.


Another thing Dr. Frank is clear about is that a diet high in nucleic acids helps heart disease patients.

He found that a high nucleic acid diet could “spectacularly” relieve angina pectoris, along with many other symptoms of heart failure, including fatigue, breathlessness, and swollen ankles.

In the No-Aging Diet, he describes how he treated a group of 50 patients ranging in age from 42 to 97 years, and mostly in their 60s and 70s. He used nucleic acid extracts and vitamins. He found that the “higher the dosage of nucleic acid, the better the results” (56).

heart disease nucleic acids rejuvenate superfood

In one case, an 83-year-old man could barely walk one half of a city block without gasping for air. Dr. Frank gave the man a physical exam, which revealed swollen ankles and feet, lung congestion, and other symptoms of heart failure. Dr. Frank started the patient of dietary RNA. Within five weeks of RNA daily plus vitamins, he could walk fifteen city blocks without troubled breathing (56).

The man’s color improved. His lungs became free of congestion. The swelling in his feet and ankles disappeared. An electrocardiogram showed marked improvement in heart function.

Then, after 2.5 months, Dr. Frank temporarily took his patient off the RNA regimen. By the second and third weeks off the regimen, the patient’s shortness of breath returned, whereupon Dr. Frank resumed treatment. Dr. Frank states in his chapter on heart disease that in the vast majority of heart patients he treated with nucleic acids he recorded a rapid reduction is both blood cholesterold and a “sharp improvement” in overall health. In two to four weeks, nearly all heart disease patients will feel better because they will actually be healthier (57).

Rejuvenate!™ superfoods provide therapeutic levels of nucleic acids in an easy-to-consume powder form that can be added to water or juice, or be put into smoothies, blender drinks, or even put on foods like salads or mixed into sauces. One of the goals in formulating the Rejuvenate!™ line was to provide a superfood that could be both tasty and therapeutic.

If you like intense greens, try Rejuvenate!™ original. For a lighter green experience with additional protein and a built-in multivitamin, go for Rejuvenate!™ PLUS (our most popular superfood). And when you’re feeling up for something especially tasty with no greens, enjoy Rejuvenate!™ Berries & Herbs.


Do you know anyone who always seems to be cold, especially in winter? They would benefit from Rejuvenate!™ superfood.

One of the more apparent benefits of consuming high-RNA Rejuvenate!™ superfoods is that you will be less cold in the winter, more tolerant of cold temperatures, and more comfortable outdoors (or indoors) in the winter. This is due to the high levels of dietary nucleic acids boosting energy production in your body.

There is also evidence, as described by by Dr. Frank, that dietary nucleic acids help the body regulate temperature more effectively, thereby not only keeping us warmer in the winter, but also more comfortable in warm or hot weather, too.

Dietary RNA supports optimal metabolism and circulation

Simply put, Rejuvenate!™ superfoods can help you stay warm in winter and comfortable in any season.


Diabetics have unique health problems that are largely unmet by conventional treatments. Dr. Frank himself suffered from diabetes and he notes that treatment for it “has hardly advanced since insulin was isolated” decades ago (64).

Dr. Frank did not use nucleic acid therapy to cure diabetes, but to considerably reduce the damage caused by it, and thereby “keep the disease at bay.”

Nucleic acids capacity to help the body utilize oxygen more effectively and repair tissues is the foundation of how they help diabetics. Dr. Frank primarily used nucleic acids, vitamins, and dietary restrictions in his protocols for diabetes.

He describes 18 patients aged 25 to 80 years of age. Some of these individuals also suffered from heart disease, and he describes how they were dramatically helped and their excessive fatigue eliminated.

Coldness in patients’ legs and feet caused by impaired circulation “completely disappeared” after two to four months of following the protocol (65).

He also describes how peripheral nerve damage (numbness) can be successfully treated with a nucleic acid diet, a vitamin B-complex tablet, plus choline and inositol (65).

Dr. Frank describes diabetes as having so many degenerative aspects that he likens it to many degenerative diseases lumped together simultaneously. He correlates degenerative disease with the aging process due to the fact that in both cases there is “less oxygen-using metabolism and more non-oxygen using metabolism, largely because of a block in the Krebs cycle or electron-transport chain” (66).

diabetes complications rejuvenate superfoods
A high-RNA diet can be an effective, useful adjunct for diabetes

In Dr. Frank’s opinion, this block means that some NADH (reduced form of NAD) (nicotinamide adenine dinucleotide) and similar molecules are not fully oxidized to form ATP. He implicates NADH produced in the less-oxygen-using metabolism as playing an actively destructive role for diabetics in producing sugar complexes (mucoproteins) that form thickening membranes inside tiny blood vessels (66).

Dr. Frank shows that high-RNA diets can help diabetics control their symptoms. High-RNA Rejuvenate!™ superfoods provide therapeutic levels of nucleic acids that can help support a comprehensive program for dealing with diabetes.


All Rejuvenate!™ superfood formulas provide a therapeutic amount of dietary nucleic acids, or about 340 mg of RNA.

340 mg of dietary nucleic acids, including RNA, is a therapeutic amount. That is, it is a dose high enough to make a difference for health.

There is no exact upper limit for dietary RNA intake. However, benefits will continue to accrue at 1,000 mg or even 1,500 mg. These include the above-mentioned benefits, such as improved tissue oxygenation, faster healing, body temperature regulation.

Some have likened the benefits of higher RNA intake levels to attaining the physiological states observed in Olympic athletes. Indeed, anyone looking to improve athletic performance should try taking 1,000 mg of nucleic acids, which is the equivalent of just four small scoops of any Rejuvenate!™ superfood.

Yet, even for the average person who is not an elite athlete, surprising improvements in physiological capacities are likely. For example, climbing stairs or lifting objects will become easier, especially if these types of activities are engaged in routinely or regularly. Dr. Frank tested human subjects performing both of these activities reported the results in both his No-Aging Diet and his technical works.


I could continue enumerating the many benefits of a Rejuvenate!™ superfoods and other high-RNA foods. It’s easy to do, and perhaps I will in separate blog post in the near future.

Other notable benefits of dietary RNA include improving functional strength and athletic performance, helping osteoarthritis, and increasing both longevity and qualify of life. In fact, it helps nearly every aspect of health because, as I mentioned, it boosts cellular energy itself, which can be used in the body to optimize nearly all physiological functions.

And so I reiterate here that most, if not all, of these benefits provided by dietary nucleic acids relate to greater cellular energy (ATP) production in the body. In fact, Dr. Frank devotes chapter three (titled “New Energy for Our Cells”) in the No-Aging Diet to highlighting the cellular mechanisms and biochemical processes involved in the body’s conversion of dietary RNA into energy it can use to support bodily processes for optimal health.

Suffice it to say that there are good reasons behind the fact that Dr. Frank’s titled his technical work (i.e., written for scientists and health care professionals) Nucleic Acid Nutrition and Therapy. He firmly believed in applying the lessons and results obtained in his laboratory for the benefit of human health. It is for these same reasons that we at HPDI developed the Rejuvenate!™ line of superfoods.



Dietary nucleic acids are found in many foods in their natural state. These nucleic acids include ribonucleic acid (RNA), deoxyribonucleic acid (DNA), nucleotides, and nucleosides. While these terms may sound complex, they are basic biology concepts taught in Biology 101. They are the genetic basis of life. The reason they are found in foods is because foods are made of living (or formerly living) matter, and living matter is full of nucleic acids.

But not all foods provide the same amounts of nucleic acids and some are decidedly low in them. Once you discover the healthy benefits of consuming dietary RNA, any how easy it is to consume it, then you will seek out foods high in RNA.

Many people aren’t familiar with the benefits offered dietary nucleic acids despite the fact that many foods (like certain fish, beans, and brewer’s yeast) are very high in nucleic acids. Many of these foods are considered healthy and recommended as part of a nutritious diet. But few foods can provide all the benefits of a superfood specially formulated not only to provide nucleic acids, but also supporting nutrients that optimize the effects of nucleic acids in the body.

Foods highest in dietary nucleic acids tend to foods high in purines. Fish and organ meats tend to be high in purines. Beans and legumes are also very high in purines, and therefore high in nucleic acids.

The pioneer researcher who essentially discovered the therapeutic value of dietary nucleic acids is Dr. Benjamin S. Frank. Dr. Frank was not only a popularizer of the importance of high nucleic acid diets, but he was also a medical doctor, molecular biologist, and researcher who tested his ideas using scientific methods.

Dr. Benjamin S. Frank, researcher of dietary RNA for health & anti-aging.

Dr. Frank published several books on the topic of dietary nucleic acids, including his 1976 bestseller Dr. Frank’s No-Aging Diet. His scientific works on the topic culminated in his highly technical Nucleic Acid Nutrition and Therapy (1979).

In the No-Aging Diet, Dr. Frank advocated consuming fish, beans, other high-RNA foods, as well as nutrients and supplements that enhance the uptake and utilization of dietary RNA. He also used various high-RNA yeast extracts in his nutritional experiments with animals. Dr. Frank includes a useful table titled “Nucleic Acid Content of Foods,” in which he provides relative amounts of dietary RNA contained in different types of foods. He derived the RNA content of foods in his table from measurements of purines. That is, Dr. Frank approximates the RNA content of foods by multiplying the purine content by a factor of 3.5.

Dr. Frank's No-Aging Diet RNA Rejuvenate

It is notable, however, that Dr. Frank was not aware that the dietary RNA content of chlorella is at least ten times higher than sardines, which is the fish exhibiting the highest levels of dietary RNA. Most fish contain more RNA when fresh or freshly cooked. Sardines are the exception, and canned sardines offer the very highest levels of dietary RNA among fish.


Fish consumption has risen dramatically in recent years. Fish can be a very healthy food. However, too often it is not, and comes with its own risks.

Problems with consuming fish include PCB and heavy metal contamination (especially for fish higher up the food chain), radiation contamination (think Pacific fish living within the massive plume from the Fukushima nuclear plant), overfishing and depleted stocks, and the poor quality and toxicity of farmed fish. In addition, fish is simply not an option for vegetarians.

Consumption of organ meats (e.g., liver, heart, kidneys, brains) has fallen rather dramatically during the last 50 years. The difficultly of obtaining clean, high-quality organ meats is part of the reason for this decline along with changes in consumer tastes. Like fish, organ meats are not an option for vegetarians.

Chicken livers provide nearly two-thirds of the amount of dietary RNA found in sardines. Other organ meats generally provide less, but good choices (at least in terms of total RNA) are beef and pork livers.

Beans and other legumes are attractive choices for everyone. They can be obtained organically grown, and they are plentiful and nutritious. Ideally, beans and legumes should be part of everyone’s diet. Depending upon the bean, a single serving of beans can provide a significant amount of dietary RNA. Lentils and pinto beans, for example, provide up to 80% of the RNA content of sardines. Other legumes, such as garbanzo beans and blackeyed peas provide less RNA, perhaps up to 50% of what sardines contain. Smaller amounts of RNA equate to fewer health benefits. Nevertheless, almost every type of legume provides a reasonable amount of RNA.

What is an ideal amount of RNA to consume daily? Dr. Frank speaks of ideal amounts, perhaps 600 mg per day up to 1,500 mg per day. The benefits obtained at higher levels will include all the benefits I talk about below (e.g., easier breathing, greater energy and functional strength, rejuvenation), and can especially benefit individuals requiring optimal nutritional status in order to heal or desiring powerful rejuvenation (such as older individuals or those in recovery).

Another group that can benefit is elite athletes (or those who wish to become elite athletes). Athletic performance, like other activities requiring exceptional amounts of energy, benefits from the ability of RNA to generate energy (as ATP) and to facilitate muscle recovery and growth.

What Dr. Frank is clear about is that regardless of what may constitute an ideal daily dose, the regular consumption of even relatively small amounts of dietary RNA will provide significant benefits out of proportion to the dose. That is, the body benefits from any amount of RNA consumed, and especially when its supply is low which is often the case in persons consuming today’s typical diet (also known as SAD, or Standard American Diet).

Dr. Frank notes that older people and athletes (both of which are groups that gain particular benefits from RNA consumption) show noticeable improvements in health and performance from what might be considered less than therapeutic amounts of RNA. This may partly be explained by the fact that dietary nucleic acids are essential nutrients like vitamins and minerals (according to Dr. Frank) and therefore the body will utilize the supply of RNA no matter how small (Nucleic Acid Nutrition and Therapy 116–117).

The work of Dr. Frank differs from that of many other nucleic acid researchers. He notes that he is far from being the only medical researcher to be interested in nucleic acids and that many scientists as far back as the 1950s were studying how nucleic acids could help humans deal with diseases. In this respect, he mentions how research is ongoing into the use of injectable organ-specific tissues (containing nucleic acids). Even today, pharmaceutical companies are busy trying to discover patentable substances that act upon the body in ways that mimic the actions of dietary nucleic acids.

Dr. Frank distinguishes himself from the approaches taken by other nucleic-acid researchers by stating that he 1) aims at improving the health of the entire body rather than individual organs; and that his focus lies in 2) using a dietary approach (not injections), and that he 3) regards nucleic acids as natural nutrients not medicines (No-Aging Diet 23).

The important research of Dr. Frank inspires the formulation of the Rejuvenate!™ line of superfoods because we, too, regard nucleic acids as natural, and indeed essential, nutrients best obtained by diet and that improve the health of the entire body.


As nutritious as they are in terms of providing dietary nucleic acids, beans and legumes come nowhere close to providing the levels of nucleic acids found in chlorella. Chlorella offers the highest amounts of nucleic acids per unit weight on the planet. Chlorella is now a popular superfood because it is easy to take, tastes good, and can be obtained in a relatively pure state.

Most people who take chlorella take tablets, which is fine. But it can be difficult to obtain therapeutic amounts of nucleic acids from tablets. Powder is a better form because it can used more flexibly, for example, in smoothies or put into foods.

But consuming 100% chlorella power presents challenges. First, it is highly detoxifying. This is good, except that detoxifying too rapidly can present the body with unpleasant symptoms (e.g., rashes) that in themselves are harmless, but may not be acceptable to some people.

Secondly, chlorella offers a unique profile of nucleic acids that while effective for boosting health, does not represent a full spectrum of RNA, DNA, nucleotides, and nucleosides.


For all the reasons I’ve considered above, we at HPDI developed the Rejuvenate!™ line of superfoods. Our intent was to create a series of superfoods that provide therapeutic amounts of a wide-range of dietary nucleic acids that would be easy to consume, taste good, and include other nutrients that help optimize the uptake and utilization of nucleic acids in the body.

The Rejuvenate!™ line of superfoods is the only superfood line providing therapeutic levels of dietary nucleic acids. Dietary nucleic acids offer major benefits for health, healing, recovery, endurance, functional strength, athletic performance, and overall well being.


The Rejuvenate!™ line currently consists of Rejuvenate!™ (original greens), Rejuvenate! PLUS, and Rejuvenate! Berries & Herbs.

It all began with Rejuvenate!™ (original greens). This Rejuvenate!™ is the “greenest” and greenest-tasting formula, and provides the highest chlorella content. It offers similar RNA content per serving to other Rejvuenate superfoods, which all provide about 340 mg RNA per serving. However, because its serving size is smaller, the original version actually offers more RNA per unit weight. Hence, Rejuvenate!™ original is the most cost-effective (42 servings per container) both in terms of cost-per-serving and cost-per-milligram of RNA. But the each Rejuvenate!™ formulas offers unique benefits of its own.

Rejuvenate!™ PLUS is our lighter, sweet green superfood (when compared to original Rejuvenate!) providing somewhat fewer greens. Consuming fewer greens is actually beneficial for individuals who wish to detoxify at a more moderate pace. Rejuvenate!™ PLUS is formulated to provide high levels of protein (about 12 g per serving) and includes complete multivitamin and multimineral complex. Rejuvenate! PLUS is our most popular Rejuvenate! superfood due to these unique benefits and features.

Rejuvenate!™ Berries & Herbs contains no greens (and is designed that way) to please the palates of individuals who either don’t like greens (e.g., chlorella and spirulina) daily or wish to ‘mix & match’ with other Rejuvenate! superfoods. Berries & Herbs still offers the same therapeutic levels (actually a bit higher than the others at 390 mg) of dietary RNA. It also provides a complete multivitamin and multimineral complex. Many consider Rejuvenate! Berries & Herbs to be the best-tasting superfood in the Rejuvenate! line. What also makes Berries & Herbs unique is a potent cell-protective herbal complex with high antioxidant value, and which promotes optimal cell function.

Rejuvenate! High RNA Superfood 


One thing Dr. Frank is very clear about is that dietary nucleic acids are more effective when used in conjunction with vitamins, especially the B complex. This is why our two best-selling Rejuvenate!™ formulas provide a complete multivitamin complex built-into them. They are Rejuvenate!™ PLUS and Rejuvenate!™ Berries & Herbs.

While Rejuvenate!™ original does not provide a complete multivitamin, HPDI also offers a complete line of multivitamins, including Multi Two (caps or tabs), Mighty Multi-Vite!™ (caps), and ultrapure Mini Multi (which contains no additives, fillers, or other excipients and is ideal for chemically or environmentally sensitive persons).

multivitamins rejuvenate superfoods

HPDI actually has created a system of four foundational supplements that act synergistically to create optimal health. The four foundational supplements include Rejuvenate!™ superfoods, multivitamins, antioxidant formulas, and essential fatty acids. You can learn more about our foundational supplement system and see why optimal health is best created using all four types of supplement formulas.

Rejuvenate!™ superfoods and other foundational supplements are also part of the HPDI Rejuvenation Program. This is our most comprehensive program for creating health, and it entails not only foundational supplements, but also enhancement formulas and specific-condition formulas that can be used to customize a regiment of nutritional supplement formulas unique to individuals.


If, as Dr. Frank compellingly argues, dietary nucleic acids are “essential nutrients,” then everyone should take them. That is, everyone who wants to be healthy, vibrant, and to look and feel younger. That’s you, isn’t it? In fact, who doesn’t want to be healthier and feel better?

That’s me for certain. I never go a day without at least one serving a Rejuvenate!™ superfood providing 340 mg of RNA. I typically take the original formula because I like intense greens and because it goes well in green drinks. But all of the formulas taste great, so I often mix and match to suit my taste.

I personally experience all the benefits I’ve described, and more. If after reading my article, you think you might gain even some of these health benefits, then wouldn’t it be worth trying the only superfood formulated specifically to provide high levels of dietary RNA?

I challenge you to try Rejuvenate!™ for yourself, and to see how well it can work to provide all the benefits for your health. Like all other HPDI products, Rejuvenate!™ superfoods are guaranteed, so you have nothing to lose.

Get started with Rejuvenate!™ superfoods today, and see why I’m not just talking about a superfood, but about a functional food that can make a significant and lasting difference for your health and for the health of your family, friends, and patients.
