Will zinc and magnesium boost testosterone levels?
✔️ Zinc can boost testosterone levels, but mainly in people who are zinc deficient. If levels are already normal, extra zinc is unlikely to help and too much can cause nausea, sickness, numbness, or weakness. Zinc is important for testosterone production and helps prevent testosterone being converted into oestrogen.
✔️ Magnesium supplementation can increase testosterone levels, especially if you are deficient. Magnesium is used in over 300 enzyme systems and plays a role in hormone regulation. The RDA for men is around 400mg, which can be found in foods like spinach, nuts, and wholemeal bread.
✔️ ZMA supplements may restore zinc and magnesium levels if there is a deficiency, but total testosterone levels are not significantly changed.
🚨 Testosterone supplements should not replace medical advice. A blood test can confirm deficiencies, and a medical professional can offer appropriate guidance. Over-the-counter supplements are not regulated and may pose health risks.
