At 15mg per capsule, you're getting **Zinc** right at the bottom of the clinical range (15–30mg) in a single dose. The picolinate form is one of the best-absorbed options available, so your body is actually using what you're taking. Follow the label's option to take two capsules daily if you want to reach the full 30mg studied dose — especially relevant for immune support and skin healing, the areas with the strongest research behind zinc.

Zinc plays a role in over 300 enzymatic processes, but for most people the practical benefits come down to immune defense, wound repair, and hormonal support. At this dose and form, you're well-covered for general maintenance.

One thing to watch at higher intake: long-term zinc above 40mg/day can deplete your copper stores. At the two-capsule dose (30mg) you're safely under that ceiling, but if you're also getting zinc from a multivitamin or fortified foods, it's worth tracking your total.
