The higher strength, said plainly
30 mg in one capsule, double our everyday 15 mg. We would rather tell you most people do not need it than sell it to someone who does not.

The higher-strength zinc, and one to take deliberately. A full 30 mg of zinc picolinate in a single capsule — double our everyday 15 mg. Most people do not need this much, and sustained high zinc intake can affect copper status. It exists for those who have been told to take it.*

Who it's for
This is the higher-strength option, and the honest answer is that most people should be on our 15 mg. Zinc is a mineral where more is not automatically better — sustained high intake competes with copper. Take this because someone qualified told you to, not because the number is bigger.
- Anyone a doctor or practitioner has specifically directed to a higher zinc intake
- People with a diagnosed reason for elevated needs, staying in touch with whoever identified it
- Anyone using it short-term for a defined stretch rather than indefinitely
- Not a starting point: if you are new to zinc, the 15 mg is the everyday amount
- Not for stacking: never alongside our 15 mg, and check your multivitamin before adding it
- Worth knowing: long-term high zinc intake can affect copper status, which is why this is not the default
- Not a substitute for advice — at this strength the right amount is a clinical question
How to take
Adults take 1 capsule daily with food, or as directed by a qualified healthcare professional. Do not combine with other zinc supplements without professional guidance
Ingredients
- Active ingredients: Zinc (as Zinc Picolinate) 30 mg
Zinc Picolinate 30 mg
How it supports you.
For an intake someone has assessed
A higher zinc amount is a decision worth making with a professional. This exists so that when it has been made, the amount is available in one capsule.
Bound to a carrier your body makes
Picolinic acid is what the body produces from L-tryptophan to carry minerals across the gut wall. Picolinate uses that route rather than fighting it.
Immune cells, built and working
Zinc is essential to the development and normal function of the immune cells the body depends on.
Skin that repairs itself
Zinc supports collagen formation and normal tissue repair, which is why it is among the most studied minerals for skin.
One capsule, not two of the 15 mg
Reaching this amount by doubling up on lower-strength capsules is the clumsier way to arrive at it.
Your own antioxidant enzyme
Zinc is a required cofactor for superoxide dismutase, one of the antioxidant enzymes your body makes for itself.
Hair and nails, over months not days
Zinc contributes to normal hair and nails, and both grow slowly enough that consistency matters more than dose.
Copper, worth watching
Sustained high zinc intake competes with copper absorption. That is not a reason to avoid 30 mg, it is a reason to take it deliberately.
Bound to a carrier the body already uses.

Inside the formula
Zinc (as Zinc Picolinate) 30 mg
Same picolinate form as our 15 mg, at double the amount. Zinc bound to picolinic acid — the carrier the body makes from L-tryptophan to move minerals across the gut wall — which is why picolinate is among the better-absorbed forms. Be clear about what 30 mg is, though: it is a deliberate, higher-strength amount rather than a default, and sustained high zinc intake competes with copper absorption. If nobody has told you to take this much, our 15 mg is the one you want.
OUR QUALITY STANDARD
Tested like it’s going into our own body. Because it is.
Quality is personal. Our standard centers on heavy-metal and microbiological testing, clear specifications, and documented results.
CAREFUL TESTING. CLEAR DOCUMENTATION.
Frequently asked questions
How do I know what's on the label is in the bottle?
Trust should be verifiable. Every batch we produce is tested by an independent laboratory, and the certificate of analysis for your exact lot is published on this page — potency, heavy metals, microbials. Testing begins the moment a raw material arrives, continues through production, and no batch is released until every result clears. The label is a claim. The COA is the proof.
How do you choose your ingredients and doses?
We formulate from peer-reviewed clinical research and dose to match it. We select the highest-grade material available for each ingredient, in the form the body absorbs best, and where a patented or branded form is the one that has actually been studied, that is the one we use. Every active appears at its exact amount, with no proprietary blends and nothing added that doesn't need to be there.
Where are CoreLabs supplements made?
In our own cGMP-certified facility in California's Central Valley. Manufacturing in-house means quality is our responsibility at every step rather than a supplier's promise. Raw materials are purchased through established US suppliers who import and qualify them, and every material is tested against our own specification before it enters production — wherever it originated.
Why are CoreLabs supplements more expensive?
Because of what goes in. We buy the highest grade of each raw material, in the most absorbable form, and we work with the branded and patented ingredient houses whose material the clinical research was actually run on — names like Lonza, Albion, RIBUS, Sabinsa and Indena. Wherever possible those materials are made domestically. Our capsules are titanium-dioxide free. Then it is made in our own facility and third-party tested batch by batch. Every one of those choices costs more than the alternative, and the price reflects it. Anyone can claim quality — we publish ours.
Should I take the 30 mg or the 15 mg?
Almost certainly the 15 mg, unless a professional has told you otherwise. Same picolinate form, same capsule, same testing — this one simply contains twice as much. Zinc is not a mineral where more is automatically better, and sustained high intake competes with copper. Do not take both.
Why zinc picolinate over other forms?
Picolinate is zinc bound to picolinic acid, the carrier your body makes from L-tryptophan to absorb minerals. It uses a route the gut already has rather than relying on stomach acid alone.
What is the copper issue?
Zinc and copper compete for absorption, so a sustained high zinc intake can gradually lower copper status. It is the main reason 30 mg is not our default and worth raising with whoever advised it.
When should I take it?
One capsule daily, with food. Zinc on an empty stomach is a common cause of nausea, and at this strength a meal matters more.
How long does a bottle last?
One hundred and twenty capsules at one a day is four months.
Higher-strength formula. Do not combine with other zinc supplements unless directed by a healthcare professional. Long-term high zinc intake can affect copper status. Keep out of reach of children. Consult a healthcare professional before use if pregnant, nursing, taking medication, or under medical supervision.
