BioStacksZinc and hormones
Zinc is a supporting nutrient for hormones 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.
What dose to look for
Clinical studies typically use 15–30 mg of zinc. Common supplement dose; UL is 40 mg/day. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
What form to look for
Avoid zinc oxide — poorly absorbed. Avoid zinc sulfate — lower absorption, may cause nausea. For best results, choose zinc picolinate or zinc bisglycinate.
What the research says
The clinical evidence for zinc in hormones is strong. Meta-analyses of 30+ trials confirm immune benefits; reduces common cold duration by ~33% Learn more
