Magnesium and Testosterone: The Quiet Mineral Most Men Are Low In
How magnesium influences free testosterone, sleep, and recovery — and which form to take.

Why magnesium matters
Magnesium influences over 300 enzymatic reactions, including those that regulate SHBG. Men with adequate magnesium tend to have higher free testosterone for the same total T.
Form and dose
Glycinate or malate at 200–400 mg/day taken in the evening supports sleep quality and recovery. Avoid oxide — it's poorly absorbed.
Frequently asked questions
- Will magnesium spike testosterone?
- It corrects a deficiency in roughly half of men. The 'spike' is more modest than marketing implies; the recovery and sleep benefits are clearer.
- Can I take magnesium with zinc?
- Yes — they don't compete. Some men prefer separating them by a few hours to optimize absorption.
