Magnesium glycinate is magnesium bonded to the amino acid glycine. It's an organic magnesium compound, and the form most commonly chosen by people who want a magnesium supplement that sits comfortably on the stomach.

For a broader look at magnesium's role in the body and the other forms available, see our Magnesium Supplements range.

Why Choose Magnesium Glycinate?

• Gentle on digestion: a common choice for people who've experienced loose stools or stomach discomfort with magnesium oxide or higher-dose formulas.
• The glycine component: glycine is an amino acid associated with relaxation, which is part of why glycinate is often chosen for evening use rather than pre-training.
• Unflavoured and easy to stack: capsule and tablet formats slot into an existing supplement routine without adding taste or mixing steps.

A note on absorption: glycinate is often marketed as the most absorbable magnesium. The current evidence is less clear-cut. A 2017 review in Current Nutrition and Food Science found that the specific magnesium form matters less than the total dose and your existing magnesium status. Glycinate's clearest practical advantage is comfort, not absorption.

Magnesium Glycinate vs Other Forms

• vs magnesium oxide: oxide is cheaper per milligram but far more likely to cause digestive upset. This is the comparison where glycinate has the clearest edge.
• vs magnesium citrate: both are organic compounds and both are well tolerated by most people. Citrate is the more common all-rounder and is also used to support regularity, while glycinate is more often chosen specifically for evening use.
• vs blends: multi-form blends combine several magnesium sources in one product. Choose a single-form glycinate if you want to control exactly what you're taking.

How to Take Magnesium Glycinate

Follow the dosage directions on your specific product, as the amount of elemental magnesium per capsule varies considerably between brands. The total capsule weight is not the same as the magnesium content.

If you're taking a larger daily amount, splitting it across two or more smaller doses through the day may support absorption better than a single large dose. Many people taking glycinate specifically for relaxation prefer to take theirs in the evening.
