Questions shoppers ask

What is magnesium glycinate and why is it used?

Magnesium glycinate — also called magnesium bisglycinate — is a form of magnesium where the mineral is bonded (chelated) to the amino acid glycine. This chelated form is widely regarded as easy on the stomach and is commonly used to support muscle function, nerve health, relaxation and sleep. It's one of the most popular magnesium supplement forms for everyday use.

What should I look for when buying a magnesium glycinate supplement?

Third-party testing and GMP-certified manufacturing are the two most important quality standards. Third-party testing means an independent lab has checked that the product contains what the label says, at the stated amount. A GMP-certified facility means the product is made under standardised, quality-controlled conditions. Non-GMO and gluten-free status are also worth checking if those matter to you.

What is the difference between magnesium glycinate and magnesium bisglycinate?

They are the same compound. Magnesium bisglycinate is simply the more precise chemical name — it describes magnesium chelated to two glycine molecules. You'll see both terms used on product labels and listings; they refer to the same form of magnesium.

Is magnesium glycinate safe to take daily?

Magnesium glycinate is generally considered well tolerated and gentle on the digestive system compared with other magnesium forms. As with any supplement, it's a good idea to follow the serving size on the label and consult a healthcare professional if you have any medical conditions or take other medications, especially before making it a daily habit.
