Reference ranges
Optimal ranges are tighter than standard lab ranges and reflect functional-medicine targets, not the populations they were derived from. Reference bands depend on sex, age, and circumstance — Juno's lab analysis layers your profile context onto the printed range when you paste a value.
Peptide relevance
Essential mineral for testosterone synthesis, immune function, wound healing, and ~300 enzymes. Plasma zinc is the most accessible assessment but a poor reflector of total body zinc — short-term intake heavily influences the reading. RBC zinc and zinc-deficiency functional markers (alkaline phosphatase activity, taste threshold testing) are more informative for chronic status but rarely ordered. Common shortfall in vegetarians, heavy sweaters (athletes), and users on long-term PPIs. Supplementation should be paired with copper at ~10:1 ratio — high-dose zinc displaces copper over months. No direct peptide effects in common stacks but zinc status affects testosterone production and wound healing (relevant to BPC-157 / TB-500 user expectations).
