Magnesium is involved in hundreds of processes in the body, and it is one of the supplements our pharmacists are asked about most. The confusing part is the number of different forms on the shelf.

What magnesium does

  • Contributes to a reduction of tiredness and fatigue
  • Contributes to normal muscle function and normal functioning of the nervous system
  • Contributes to normal psychological function
  • Contributes to the maintenance of normal bones and teeth

Why so many forms?

Magnesium in a supplement is always bound to another molecule, and that partner gives the form its name. The label shows two numbers: the weight of the compound and the amount of elemental magnesium. Compare products by elemental magnesium.

  • Glycinate / bisglycinate: magnesium bound to the amino acid glycine (a "chelate"). Some people find it gentle on the stomach.
  • Citrate: magnesium bound to citric acid; a widely used form.
  • Taurate: magnesium bound to the amino acid taurine.
  • Lactate: the form used in FutureYou Magnesium+, paired with vitamin B6.
  • L-threonate (Magtein®): a newer, branded form.
  • Combination products mix several forms in one tablet.
