Top 10 products ranked

Why Zinc for Skin

Zinc plays a supporting role in skin. Involved in over 300 enzymes and critical for immune function, wound healing, protein synthesis, and DNA repair. Zinc picolinate and zinc bisglycinate are the best-absorbed supplemental forms, while zinc oxide has poor bioavailability. In clinical studies, zinc promotes skin healing.

What dose to look for

Clinical studies typically use 15–30 mg of zinc. Common supplement dose; UL is 40 mg/day. Products below this range may not deliver meaningful results.

What form to look for

Avoid zinc oxide — poorly absorbed. Avoid zinc sulfate — lower absorption, may cause nausea. Look for zinc picolinate or zinc bisglycinate for better absorption.

What the research says

Zinc has strong clinical evidence for skin benefits. Meta-analyses of 30+ trials confirm immune benefits; reduces common cold duration by ~33% Learn more
