How does magnesium bisglycinate differ from other forms of magnesium, and why does it matter? — Magnesium Glycinate Capsules N90 - Swanson

Magnesium is available in various chemical forms: oxide, citrate, malate, glycinate and others. The difference between them lies in the compound the mineral is bound to, and this affects absorption and tolerability.

This product uses magnesium bisglycinate in the Albion® chelated form. The chelated form means that the magnesium is bound to the amino acid glycine. This compound is stable in the digestive tract and needs no further conversion to be absorbed. That is why bisglycinate is often chosen by people who have already tried other forms of magnesium and experienced stomach or bowel discomfort — for example, the laxative effect typical of oxide or citrate at high doses.

Glycine itself is an amino acid involved in the functioning of the nervous system, so combining magnesium with glycine is considered physiologically sound. This is not a marketing argument but a clear point of reference when choosing the form of a supplement.

Albion® is a manufacturer specialising in chelated minerals. For the buyer, this means that the form meets the chelation standard rather than simply being called “chelated” on the label.

If you are taking magnesium for the first time or switching from another form, it makes sense to start with the recommended dose and monitor how your body responds in the first few days.
