FAQs
Frequently asked
Why is zinc bonded to methionine?
Bonding zinc to methionine (OptiZinc) significantly improves its absorption and cellular uptake compared to standard zinc salts.
When is the best time to take ZMA-type supplements?
ZMA-type supplements, including zinc monomethionine, are typically recommended before bed to align with the body's natural overnight hormonal recovery processes.
Can I take zinc monomethionine with other supplements?
Yes, but avoid taking it with high-dose calcium. It is often combined with magnesium and Vitamin B6 in a ZMA stack for synergistic effects.
Research summary
A plain-English read of the literature behind this supplement. Not a clinical recommendation.
OptiZinc absorption studies favor it over zinc sulfate. ZMA original trials show modest T elevations in zinc-deficient athletes.
