Zinc
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Take 15-30 mg/day of zinc (as zinc picolinate, gluconate, or bisglycinate - better absorbed than zinc oxide). Do not exceed 40 mg/day from all sources. Take with food to prevent nausea. If taking for more than 3 months, add a copper supplement (2-3 mg/day) as zinc depletes copper.
How it works
Zinc is a cofactor for over 300 enzymes and is essential for testosterone synthesis, sperm production, and 5-alpha-reductase regulation. In prostate tissue, zinc accumulates in mitochondria and inhibits the Krebs cycle in a controlled manner that supports epithelial cell apoptosis - a mechanism thought to prevent uncontrolled prostate cell proliferation.
Where to buy
Thorne Zinc Picolinate ($12-$18/60 capsules), NOW Foods Zinc Picolinate ($8-$12/120 capsules), Garden of Life Vitamin Code Zinc ($15-$22/60 capsules) - at pharmacies, health food stores, and online.
Typical cost: $8-$20/month.
Safety notes
Do NOT exceed 40 mg/day of zinc long-term - chronic high doses (>100 mg/day) cause copper deficiency (severe neurological effects), impair immune function, and reduce HDL cholesterol. If supplementing for more than 3 months at 30+ mg/day, add 2-3 mg/day copper. Zinc interacts with quinolone and tetracycline antibiotics (reduces absorption) - space by 2 hours. High-dose zinc supplements (150 mg+) are associated with prostate cancer risk increase in observational data - stay within the 15-40 mg range.
