At 22mg per capsule, you're getting a solid dose of **Zinc** right in the middle of the 15–30mg range used in clinical research on immune function and skin health. That's double the RDA and enough to meaningfully support your immune system, wound healing, and the enzymatic processes behind healthy skin and hair. One capsule a day covers it.
The picolinate form is one of the best-absorbed versions of zinc available, so your body can actually use what you're taking. This matters because zinc absorption varies dramatically by form — and here you're getting the top tier.
The only thing to keep in mind: if you're taking this long-term, zinc can gradually deplete your copper stores. At 22mg you're well under the 40mg upper limit, but if you supplement daily for months, adding 1–2mg of copper is worth considering.
