What magnesium does

Magnesium is involved in more than 300 processes in the body, including muscle contraction, energy production and nervous system function. Hard training and heavy sweating increase what you lose, which is why it turns up in recovery, sleep and electrolyte products.

How much is in these products

  • Typical serve: 200 to 400 mg of elemental magnesium.
  • Glycinate (bisglycinate): gentle on the stomach, popular in evening and sleep formulas.
  • Citrate: well absorbed, more common in daytime and electrolyte blends.
  • Oxide is cheap but poorly absorbed. Check the form on the label.

How to use it

Evening is the most common time, with or without food. Split larger doses across the day if they upset your stomach. See also our electrolytes and recovery ranges.

Always follow the directions on the label. Dose ranges above describe how these products are commonly formulated, not medical advice.
