What it does

One whole food. Profound results.

Every nutrient works in synergy, the way nature packaged them. That's something a synthetic supplement can never replicate.

Energy & Vitality
Zinc and B12 support mitochondrial function and red blood cell production, the foundation of real, sustained energy.
Hormonal Balance
The iodine and selenium combination is critical for thyroid function, PMS relief, fertility support, and healthy testosterone levels.
Immune Strength
Zinc is the most studied immune-supportive mineral. Oysters provide it in its most bioavailable, food-matrix form, not oxide or gluconate.
Copper Balance
Years of standalone zinc supplementation depletes copper. Oyster naturally restores the copper-zinc ratio your body was designed to maintain.
Why Oyster?

200 million years of nutritional perfection

Oysters are one of the oldest creatures on Earth, and one of the most nutritionally complete foods humans have ever eaten.

A single oyster contains more zinc than any other food on the planet.

200 million years of <em>nutritional perfection</em>
What's Inside

Every nutrient, explained.

Pure Oyster contains one ingredient: whole dried Irish oyster. Here's what that means for your body.

Mineral
Zinc
~8–12mg per serving
The most abundant mineral in oyster. Supports immune function, testosterone production, skin health, and wound healing. The most bioavailable food-form of zinc available.
Mineral
Copper
~1–2mg per serving
Zinc's essential co-factor. Most people supplementing zinc are unknowingly depleting copper. Oyster provides both in the right natural ratio, no imbalance, no deficiency.
Trace Mineral
Selenium
~30–50mcg per serving
A powerful antioxidant and thyroid co-factor. Works in tandem with iodine to support hormonal health, fertility, and healthy thyroid conversion of T4 to T3.
Trace Mineral
Iodine
~80–120mcg per serving
Critical for thyroid hormone synthesis, yet chronically deficient in modern diets. Ocean-sourced iodine from oyster is gentler and more balanced than isolated supplements.
Vitamin
Vitamin B12
~12mcg per serving
One of the richest dietary sources of B12, exclusively found in animal foods. Essential for neurological health, DNA synthesis, and energy metabolism.
Trace Minerals
59 Trace Elements
Full spectrum
Manganese, iron, magnesium, phosphorus, and 55 more, all in naturally occurring ratios that synthetic supplements can't replicate. The full picture of mineral nutrition.

How to Use

Simple. Consistent. Effective.

01
Take 2 capsules daily
With or without food. Most people find consistency is what matters most, same time each day helps make it a habit.
02
Stack thoughtfully
If you're currently supplementing zinc on its own, consider replacing it with Pure Oyster, you'll get zinc plus the copper that keeps them in balance.
03
Give it 4–6 weeks
Mineral repletion takes time. Most customers notice changes in energy, mood, and skin within the first month. Deeper hormonal benefits build over 2–3 months.
Questions

Frequently asked

Is this safe if I have a shellfish allergy? +

Most shellfish allergies are reactions to crustacean shellfish (shrimp, crab, lobster) not mollusks like oysters. That said, if you have a confirmed molluscan shellfish allergy, please consult your doctor before taking Pure Oyster.

Can I take this if I'm pregnant or breastfeeding? +

Oysters are a whole food, not an extract, and many of the nutrients they contain (zinc, iodine, B12) are especially important during pregnancy. We recommend speaking with your healthcare provider to confirm the right dose for your situation.

How is this different from a regular zinc supplement? +

Most zinc supplements are isolated minerals, zinc oxide, zinc gluconate, or zinc picolinate. These forms lack the cofactors that make zinc usable, and taking them alone depletes copper. Pure Oyster provides zinc in a whole-food matrix alongside copper, selenium, iodine, and 55+ other trace minerals — the way your body was designed to receive it.

Does it taste like oysters? +

The capsules are unflavored. Some people notice a very mild sea-mineral scent when they open the bottle, but there's no taste when you swallow the capsules. It's genuinely easy to take.

How long does one bottle last? +

The 90-capsule bottle is a 45-day supply at the recommended 2 capsules per day.
