QUICK ANSWER
- Zinc deficiency lowers testosterone; correcting it raises it.
- Men who already get enough zinc gain little from more.
- The adult upper limit is 40 mg a day from all sources.
Why zinc matters
Zinc is needed for normal testosterone production and sperm health. A 2023 systematic review confirmed the link (PubMed).
Correction, not a boost
If you are low, restoring zinc helps. If you are not, extra zinc does little for testosterone.
Upper limit and stacking
NIH sets 40 mg a day as the adult upper limit (NIH ODS). Too much over time can lower copper. Because ErecPower does not publish its zinc amount, avoid stacking another zinc supplement without advice; see our safety guide.
Food sources
Oysters, beef, crab, pumpkin seeds, chickpeas and fortified cereals are good sources.
Zinc in ErecPower
Zinc is one of the two best-supported ingredients, alongside Tongkat Ali. See the full ingredient panel.
