Zinc is an essential nutrient involved in immune function, DNA synthesis, wound healing and normal reproductive physiology.
Deficiency vs Supplementation
Correcting zinc deficiency can matter clinically. That does not mean higher intake improves sexual function in people who already have adequate zinc status.
Dose Context
EndoPeak is reported to provide 20 mg of zinc per serving. Total intake should include food and any other supplements.
Too Much Zinc
Excessive long-term zinc intake can interfere with copper status and cause gastrointestinal effects. NIH publishes an adult tolerable upper intake level of 40 mg/day from all sources for most adults.
What This Means for EndoPeak
The presence of zinc is nutritionally plausible, but it does not prove the complete EndoPeak formula will improve erectile function or testosterone in an individual user.

Who May Be at Risk of Low Zinc
Dietary pattern, gastrointestinal conditions and other factors can affect zinc status. A clinician can help determine whether deficiency is plausible.
