How to Choose the Best Magnesium Supplements
Magnesium glycinate is a popular, highly absorbable form that is gentle on the stomach and often chosen for sleep and muscle relaxation, while citrate and other forms have their own uses. Look for third-party testing or certification, a clear elemental magnesium amount per serving, and minimal unnecessary fillers. Capsules, tablets, and powders each offer different convenience. Avoid mega-doses unless advised by a professional, since too much can cause digestive upset. Consult a healthcare provider about the right form and dose for your needs.
