Zinc Picolinate

Zinc is a cofactor in over 300 enzymatic reactions — immunity, protein synthesis, wound healing, and cell division all depend on it
Picolinate form has superior absorption versus oxide (the cheap form found in most multivitamins)
Zinc deficiency directly lowers testosterone — supplementation restores levels in deficient individuals
Always pair with copper — zinc and copper compete for absorption; high-dose zinc alone depletes copper over time
15–25mg elemental zinc daily is the studied range; the INLIFE formula pairs zinc with 1mg copper at the correct ratio
