Magnesium Glycinate and Bisglycinate Supplements

Choosing a magnesium bisglycinate supplement

Magnesium bisglycinate (also labelled magnesium glycinate) comes in a few forms, so you can pick what fits your routine:

• Capsules — the most common, easy for a daily dose.
• Powders & effervescent drinks — mix into water; easy to adjust the amount.
• Liquids — gentle and simple to take.
• Gummies — a tasty option (see our magnesium gummies).

You'll also see different strengths (commonly 100–200 mg of elemental magnesium per serving), and some formulas add ingredients like L-theanine or ashwagandha for extra calm. For children, see our Magnesium for Kids collection.

Magnesium glycinate vs bisglycinate: what's the difference?

“Magnesium glycinate” and “magnesium bisglycinate” are used interchangeably — they're the same compound: magnesium bound to the amino acid glycine. (“Bis” just means two glycine molecules per magnesium.) This form is well absorbed and gentle on the stomach, which is why it's such a popular daily choice. When comparing products, check the label for the elemental magnesium per serving — that's the number that varies.
