Why Zinc for Stress & Mood

Zinc plays a supporting role in stress & mood. 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.

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 stress & mood benefits. Meta-analyses of 30+ trials confirm immune benefits; reduces common cold duration by ~33% Learn more
