OysterMax® Capsules
Oyster Max® Zinc Supplement – Pure Oyster Extract for Immune, Energy & Hormonal Support
What Our OysterMax® Zinc Supplement Is and Why It’s Unique:
OysterMax® is pure, organic oyster tissue extract — encapsulated and dehydrated with no added ingredients. The oysters are wild-harvested from pristine Atlantic waters off the coast of Ireland and dried at low temperatures to preserve nutrients. Shells are removed before processing.
Each batch is rigorously tested for pathogens, heavy metals, and other contaminants and is rejected if even trace issues are found. The result is a supplement that is exceptionally clean, potent, and safe — with very low histamine content.
OysterMax® is naturally rich in highly bioavailable minerals — including zinc, copper, selenium, iodine, and a wide spectrum of trace elements. Each capsule contains the extract of half of a wild oyster, delivered in a small, easy-to-take form.
This is the most powerful natural supplement available for raising zinc levels — in perfect balance with copper — and supporting whole-body mineral status.
Why You Should Take OysterMax® Zinc-Rich Capsules:
The primary reason to take OysterMax® Tissue Extract Capsules is their exceptional concentration of four immune-critical minerals — zinc, copper, selenium, and iodine — delivered in the most bioavailable form nature provides. Unlike synthetic supplements, these nutrients occur in their natural matrix and are readily recognized and absorbed by the body.
Beyond zinc, OysterMax® provides the full spectrum of ocean-derived trace minerals, along with a broad range of naturally occurring vitamins and amino acids. Because these nutrients are highly assimilable, they are absorbed and utilized by your blood and cells far more efficiently than standard supplements — resulting in stronger immune support and better overall health outcomes.
Backed by Marine Science – Fortified by Nature
OysterMax® delivers a powerful spectrum of naturally occurring antioxidants, trace elements, and peptides shown to support the body’s innate response to oxidative stress and help maintain healthy cellular balance.*
- Preliminary research suggests that consistent use of OysterMax® may significantly support antioxidant status. In one study, free radical load was observed to decrease by up to 90% after just 8 days—and by up to 40% after a single day of use. (View Study PDF)
This unique formulation, rich in naturally bound zinc, copper, selenium, and superoxide dismutase (SOD), helps fortify the body’s natural antioxidant defenses for a rapid response to modern-day stressors.*
Clinical Reference:
Independent in vitro and in vivo testing conducted on OysterMax® (2015) demonstrated a measurable reduction in free radical load following short-term supplementation. Results indicated antioxidant effects after both one-day and eight-day protocols. Read full study.*These statements have not been evaluated by the Food and Drug Administration.

Supports Antioxidant Defense – Marine-Based Formula
The oysters from which OysterMax® Zinc supplement is made are harvested from specific, deep ocean regions off the coast of Ireland.
These oysters contain the maximum possible amount of trace elements and no toxicity. Each batch of OysterMax® is analyzed for heavy metals, microbiological profile, and other listed analytical constituents so that you can be assured what the label says is accurate 100% of the time. OysterMax® contains no pathogens, mercury, or other heavy metals!
Oysters are the highest natural source of zinc, 10 times higher than the next highest source, grass-fed beef (grain-fed beef has half the zinc as grass-fed beef).
The minerals in Oyster Max® are naturally bound to free-form, amino acids that transport the minerals into the bloodstream without the need for digestion.
Laboratory studies have shown perfect assimilation of the minerals and amino acids in OysterMax®. And, happily, OysterMax® contains all essential amino acids, numerous vitamins, fatty acids, 59 trace elements and much more. It's truly a surefire way to help avoid nutrient deficiencies.
Oyster Max® does not contain any fillers or excipients. Because it is a naturally balanced food, there is no danger of becoming unbalanced if one takes higher doses than normal to replenish a low level of cellular zinc (which is common in North America). Each bottle of OysterMax® contains 120 Capsules.
OysterMax® is approved under Ireland's Sea Food Protection Authority (SFPA), and Health Executive Authority (HSA), and is registered with the Financial Services of Ireland. It is compliant with Commerce and Foreign Trade regulations for export to the USA (under the FDA).

OysterMax® Zinc Supplement — Begins With Superior Oyster Harvesting
The Oysters in OysterMax® are harvested wild from deep ocean regions that produce hardier and more nutrient-dense oyster tissue than shallow regions or farmed oysters — using techniques perfected by Stephen Kavanagh's family, who have harvested wild oysters for the past 100 years. Such oyster tissue is naturally high in zinc and the other co-factors that help wild, deep-ocean oysters to have powerful immune systems. Oysters from these North Atlantic locations are also free of heavy metals and man-made pollutants (as proved by continuous assays).
Supplementing the diet with a specific food that contains a high level of natural organic zinc can be an extremely valuable part of your overall health regime since 80% of everyone is deficient in zinc. OysterMax® also has important zinc co-factors such as copper, iodine, and selenium. The trace elements in OysterMax® are balanced with each other as nature intended, because they come from a natural living source, not from a chemical factory. Together these elements along with many of the other micro-nutrients in OysterMax® provide many health activations/benefits in the body, including superior free radical quenching, as discussed at this web page.

Ten Reasons Why OysterMax® Capsules Are a Superior Zinc Supplement
— by Stephen Kavanagh, Marine Biologist
Zinc deficiency affects over 80% of the adult population. It is a vital trace element required in over 300 enzyme reactions in the body. Athletes, pregnant and lactating women, sexually active males and anyone feeling the stresses and strains of modern life all have increased demands for zinc. The clinical range of the symptoms of zinc deficiency includes decreased immunity, low libido, poor skin, hair and nails, macular degeneration, prostate health issues, and hormonal imbalance.
For those of us who feel they need more zinc than our diet provides the job of choosing the right zinc supplement can be daunting as there are so many brands and stories on the market. Choosing oyster capsules is not something many may have considered, but as nature's highest source of naturally occurring zinc, they are certainly worth a try. The rest of this article will give you ten reasons why oyster extract capsules are the superior zinc supplement on the market today.
- 🦪 Oysters are the highest NATURAL source of ZINC, ten times higher in fact than the next source which is wild-range, grass-fed beef.
- 🌊 Oyster capsules not only contain zinc, but they also contain all of the 59 TRACE ELEMENTS our body needs for the correct physiological functioning of all the biochemical pathways.
- 💧 The zinc in oyster capsules is naturally bound to amino acids which makes it very BIO-AVAILABLE. This is more effective than chelated zinc supplements and far superior to synthetic zinc supplements.
- ⚖️ The zinc in oyster capsules is BALANCED with other key co-factor elements such as copper, manganese and selenium in a way that makes them work better together. This balancing is done by nature, as nature intended. No other zinc supplement can boast this fact.
- 🧬 Oyster capsules are not only high in zinc, but they also contain MANY OTHER INTERESTING COMPOUNDS which benefit general health. Studies have shown that these other compounds can increase Glutathione levels, counteract fatigue, increase immunity and improve sexual health.
- 🏋️ Oyster capsules are classed as a Superfood. Because they are not synthetic there is NO DANGER OF UPSETTING the body's biochemistry by taking more than 4 capsules a day. People taking 12-16 capsules daily have reported zero fatigue. Many athletes take higher doses due to their increased demands with amazing results.
- 🧘 The holistic effect on the body's biochemistry of using oyster capsules has been well-documented since ancient times. In traditional Chinese medicine, oyster extract has been used for centuries for LIVER CLEANSING and SEXUAL HEALTH.
- 🧪 Oyster capsules are CUTTING-EDGE NUTRITION. Research is currently being carried out in several institutions around the world to investigate what other bio-active compounds they contain and to better understand the positive health benefits users report.
- 💰 Oyster capsules are COST-EFFECTIVE. Taking them ensures your body's biochemistry is well balanced. Taking lots of synthetic, elemental trace element supplements in the hope of achieving the same result is far more risky and more expensive.
- 🌍 The production of oyster capsules is sustainable and because the oyster shells lock carbon out of the atmosphere there is a net REDUCTION IN ATMOSPHERIC CARBON from the process.
A cautionary note: Not all oyster extracts are the same. Some oysters can be up to 20 times more potent in terms on zinc concentration than others. This is due to differences in region and seasonal harvesting applied by the different manufacturers. This difference is also usually reflected in the price. Our oyster tissue does not include the shell as do some other manufacturers.
Some People Needlessly Avoid Oysters — and Lose the Single Best Natural Source of Zinc
(Why OysterMax® may be the most overlooked immune-support powerhouse available)
There’s a persistent myth that oysters are unsafe — that they accumulate toxins, pathogens, or heavy metals simply because they live on the ocean floor. That may be true in polluted harbors or industrial shellfish farms, but it’s categorically false when it comes to our wild, deep-ocean oysters.
OysterMax® is made exclusively from wild oysters harvested from pristine Atlantic waters far offshore, where pollution is non-existent and the environment is naturally clean and mineral-rich. These oysters are not farmed or dredged from estuaries. Instead, they’re pulled from deep marine ecosystems where they feed on nutrient-dense plankton and decaying organic matter that drifts down from the upper ocean — a natural mineral infusion you simply can’t recreate in a lab.
Every batch of OysterMax® undergoes rigorous testing for heavy metals, microbial pathogens, and other contaminants. If it doesn’t meet our highest safety standards, we reject it. Period. Our standard is not "good enough." It’s "exceptional or nothing."
Why Oysters (Especially Ours) Are the Most Underrated Superfood on Earth
Deep-ocean oysters are uniquely rich in zinc, copper, selenium, iodine, and dozens of other trace elements the body needs to function optimally. These minerals exist in oysters in their most bioavailable, natural matrix-bound forms — meaning your body can absorb and use them more efficiently than any synthetic supplement.
Unlike isolated mineral pills, OysterMax® offers nature’s own balance — minerals paired with naturally occurring amino acids, peptides, and co-factors that enhance absorption and synergy.
Oysters possess some of the most powerful immune factors in nature. Why? Because they live exposed to everything the ocean throws at them — viruses, bacteria, toxins — yet remain resilient. Their internal chemistry contains compounds evolved to resist infection and neutralize invaders. When you consume OysterMax®, you benefit from this ancient, marine-based immune defense system.
A Forgotten Staple of Human Health and History
It’s easy to forget that oysters weren’t always rare or exotic — they were once a dietary mainstay for working-class families and immigrants. In the 19th and early 20th centuries, oysters were the most affordable and nutrient-dense food available in American port cities. European immigrants relied on them to survive during difficult transitions — not just because they were cheap, but because they were packed with essential minerals and protein.
In an age of mineral-depleted soils and over-processed food, OysterMax® brings back the density and integrity of real nutrition — exactly what built generations of resilient, working-class health.
Final Thought
If you're taking synthetic zinc or selenium supplements while ignoring nature’s richest, most balanced source of these minerals, you may be wasting your time — and shortchanging your immune system.
OysterMax® is what serious, informed people take when they’re done with half-measures.
The Many Ways Oyster Max ® Helps
Oyster Max® Zinc Capsules Help in Avoiding Fatigue
Undoubtedly to give themselves superior pathogen fighting powers, oysters take zinc from ocean water and concentrate the zinc into their tissues. That's why OysterMax® has a high level of organic zinc. When consumed by humans this will enable people's cells to create more endogenous antioxidants, especially, super oxide dismutase (SOD) and glutathione. Not only will these antioxidants help boost the immune system but will also help quench free radicals within the mitochondria and help prevent mitochondrial free radical overload which is a main cause of tiredness.
In general, Oyster Max® helps protect the body from oxidative stress. Studies show that consuming OysterMax® for just eight days reduced free radical blood stress by 90%. Endurance athletes, stressed out professionals working long hours, individuals exposed to environmental stresses such as UV light, smoking, excess alcohol consumption, may all suffer from higher than normal levels of oxidative stress and free radical build up. OysterMax® protects from the fatigue and tiredness associated with this oxidative stress. The bottom line is that you will be able to function optimally, longer, and under more stressful situations, which is why OysterMax ® is used by French Military Special Forces to increase the survivability of their troops.
Oyster Max® Zinc Capsules Help Boost Immunity
- Oyster extract powder can boost the immune system.
- Oyster extract powder can help ensure normal functioning of the immune system.
- OysterMax® contains a minimum of 3.0 mg of natural organic zinc per 4 capsules (trace element concentrations in natural products can vary considerably). This is a safe amount of natural organic zinc to supplement your healthy varied diet. It also contains significant amounts of selenium, copper and iodine that all support the immune system.
Oyster tissue contains ten times more zinc than any other food/animal. Scientists believe the reason for this is that their system is "open" to the sea, allowing seawater (and whatever is in it) to freely enter inside them, including pathogens. Therefore, they need to have a very strong immune system in order to kill the harmful bacteria that enter. The process by which oysters kill those bacteria involves sending out large amounts of free radicals to attack and destroy the harmful bacteria. Unfortunately, those free radical attack forces will do collateral damage to the oyster's own tissues unless the oyster's own tissues can protect themselves. In order to protect themselves, oysters intake large amounts of zinc from the ocean water in order to produce large amounts of the fastest-acting antioxidant, namely, super oxide dismutase, which can neutralize immune system generated free radicals. The nice part for us that that eating Oyster Max® provides bioavailable zinc, a mineral known to support normal immune system function and antioxidant defenses. This is a powerful reason to consume OysterMax®.
OysterMax® Zinc Capsules Help With Having aHealthier Pregnancy
Pregnancy dramatically increases nutritional demands for expectant mothers. If a pregnant mother isn't eating enough of a particular nutrient to supply both her own body and the developing baby's body, nature favors the baby. That nutrient will be taken from the mother's own body and be supplied to the baby. The mother's health will decrease as a result. Of course, if a nutrient low supply in the mother's body, it is possible that neither the baby nor the mother will have enough of it for optimal health. That's why all pregnant mothers are encouraged to eat as nutritiously as possible, so that neither their own health or the health of their baby suffers.
Because OysterMax® is natural and contains all the nutrition of the sea (all the essential amino acids, fatty acids, minerals, trace minerals and vitamins) it is the perfect supplement to help meet those increased nutritional demands during pregnancy so that both the baby and mother can be optimally healthy and the baby can grow perfectly. Unlike raw oysters, it is also completely safe for pregnant mothers. Check out this articles regarding healthy pregnancy:

OysterMax® Zinc Capsules Help with Having More Beautiful Hair and Skin
OysterMax® nutrients help significantly:
- Zinc and Iodine contribute to the maintenance of beautiful hair, nails and skin.
- Copper contributes to beautiful hair and skin pigmentation
- Copper, Zinc and Selenium contribute to the protection of cells from oxidative stress
- OysterMax® contains high levels of amino acids. Free amino acids are very useful as they do not need to be digested and they enter the blood stream directly and go to where the body needs them most. Three of these, Glutamic acid, glycine and Cysteine are the building blocks for collagen. Free Cysteine is normally toxic to the body and having a non-toxic source of bio-available Cysteine is very advantageous for collagen production in the body. The rest of the amino acids in OysterMax® are involved in the manufacture of enzymes, antioxidants and structural proteins such as keratin.
Supplementation with our OysterMax® Zinc Capsules Helps in Regard to Delaying Aging
- OysterMax® oyster supplement contains many of the building blocks for the body’s antioxidant defenses. Free radical damage is one of the major causes of premature aging in tissues, especially the skin, where wrinkles and damaged skin often result as one ages.
- Also, free radicals attack joints and create joint stiffness and pain. Free radical damage in the mitochondria reduces the mitochondria's ability to produce energy and leads to overall loss of vitality and endurance.
- Skin aging, joint stiffness and loss of energy are three of the most noticeable and unwelcome aspects of aging. OysterMax® helps combat all of these, helping one to stay "young" much later in life.
Supplementing with OysterMax® Zinc Capsules Is Helpful in Regard to Better Sexual Health
OysterMax® nutrients support the maintenance of normal testosterone levels in the blood. High levels of zinc are found in sperm and the prostate gland. Sperm contain 700 times more zinc than is found in blood plasma. The prostate contains more zinc than any other organ in the body. Therefore, it is extra important for men to seek good dietary sources of zinc. Oysters are the single best source of zinc (much better than chelates or any other laboratory produced form of zinc supplementation). Oysters also boost dopamine, a hormone that increases libido and sense of well-being in both men and women.
OysterMax® Zinc-Rich Capsules Helps in Regard to Having Better Cardiovascular Health
OysterMax® nutrients help maintain the metabolism of fatty acids, which fatty acids are essential to cardiovascular health. Also, its zinc and copper content help form antioxidants that protect the cardiovascular system from damage. Finally, copper is essential to the integrity of cardiovascular linings. Oysters are also high in potassium and magnesium which can help reduce your risk of heart attack, stroke and lower blood pressure. A study done by the University of Washington found that eating oysters can help raise the HDLs (good cholesterol levels) and lower the LDL’s (bad cholesterol levels).
Oyster extract is the dried flesh of the oyster
Oysters are harvested, opened and their flesh is removed and powdered through a drying process that kills all bacteria. One of the secrets of OysterMax® is that they are harvested at those seasons when zinc content is its highest. Oyster powder is mineral rich — it contains all minerals and trace minerals needed by the body (because they are present in the ocean and concentrated in the oyster flesh) as well as vitamins, amino acids, taurine and omega oils. Oysters have the highest natural source of the trace element zinc. Only oyster extract harvested at times of the year when zinc potency is highest can boast this claim, and very few of the companies making oyster extract recognize this.
Why Oyster Max® Concentrates Zinc, Copper, Selenium and Iodine Within Itself
Our oyster powder contains natural, organic, bio-available zinc in greater amounts than any other food on planet earth. The oyster accumulates zinc to much higher levels than any other animal known. The reason for this zinc accumulation surely has a lot to do with the oysters immune system. The oyster operates an open circulation system and when invading bacteria enter the oyster, the oyster’s immune response must immediately spring into action. During this defense a process called the ‘metabolic burst’ occurs which results in the destruction of the invading pathogen but also results in the release of large amounts of free radicals which could harm the oyster's own tissues and organs (a type of collateral damage) if the free radical burst were not eliminated. To mop up the excess burst of free radicals the oyster produces large quantities of an anti-oxidant called SOD or superoxide dismutase. However to make SOD the oyster needs large amounts of zinc, and this is considered to be the most likely reason why they have such high levels of zinc in their bodies.
The good news for us is that since most of us are very low in zinc, eating oysters allows us to also have a very significant benefit to our own immunity and free radical defense systems. The zinc in OysterMax® comes bound in transport molecules that will make it highly bio available as opposed to the synthetic and chelated alternatives that aren't so bio-available.
You Are What You Eat — Which is Why We Recommend Our Oyster Max® Zinc Supplement
Stephen Kavanagh is the marine biologist behind OysterMax®. With over 30 years of experience in marine science, he’s dedicated to advancing human health through ocean-based nutrition. He is pictured here at his restaurant in the Temple Bar Food Market in Dublin.
How he got started with OysterMax, in his own words:
“I’ve always loved the sea. My father was a master mariner, so growing up in Arklow, you could say my brothers and I had salt water in our blood from an early age. I spent a few weeks aboard the Bord Iascaigh Mhara (BIM) research vessel on the Irish Sea, then studied for a year at NUI Galway. After completing my degree at the School of Ocean Sciences in North Wales, I worked in London, and later entered the oyster business on the West Coast.
When I returned home, I started my own company processing oysters. I often say my business really spans four or five different areas — I began as an artisan oyster processor, and we gradually evolved into making extracts and developing other marine-based products.
When it comes to health, the best way to eat oysters is fresh — but not everyone has access to safe, fresh oysters. For those concerned about nutritional deficiencies, oyster extract capsules are a great solution. Today, in addition to supplying restaurants and delis with smoked oysters, we also work with integrative doctors in France and the U.S. who use our extracts to support their patients’ health.”
Food is the way of health not vitamins!
Oyster Max fits with the “first rule of health” which is that food should be our medicine. Oyster Max also fits with our second rule of health, which is that food engenders health, not vitamins. The United States has among the worst health statistics of all industrialized nations, yet the people of the United States consume more vitamins that the rest of the world combined. That means that you will eventually find, as so many others have already found, that your health will never really start to improve until you give up on vitamins and turn to food. It's time to turn to food!
- Vitamins, IE nutrient isolates (often made in a laboratory), may look powerful and awesome on the label, but they don’t work as well in the human body as one would hope because they lack the many needed co-factors. Food comes with many needed co-factors nutrients.
- The lack of co-factors is the basic problem of vitamin supplements. Without those co-factors, they're NOT as useful to our cells. For instance, Vitamin C is not just ascorbic acid but rather it is: ascorbic acid and numerous co-factors that work in the cells like catalysts or tag teams to make chemical reactions occur. The many co-factors are present in foods, but are not in vitamin isolates. The result, therefore, of taking vitamins is that the body has to scavenge body tissues to obtain the needed co-factors, or wait until they are available or the body may simply discard the nutrients for which co-factors are not available. This is extra work and/or a waste of nutrients, and therefore, vitamin isolates, do far less to improve health than does food.
