Why Zinc for Stress & Mood
Zinc is a supporting nutrient for stress & mood support. 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. Long-term zinc supplementation above 40 mg/day can deplete copper stores—pairing with 1–2 mg copper is recommended at higher doses.
How much zinc do you need
