Best Capsule Antioxidant Supplements in 2026

Thorne built this one around zinc picolinate, a chelated form that tends to sit easier on the stomach than the bargain-bin zinc oxide hiding in cheap multivitamins.

It's one small capsule a day, easy to swallow, no chalky finish. Thorne's third-party content certification also means the label matches what's actually in the bottle, which is not a claim every brand can honestly make. A quiet, dependable daily mineral rather than a flashy one.
