Magnesium Glycinate — Best Bioavailable Form
Magnesium Glycinate — Best Bioavailable Form
Why choose magnesium glycinate?
Magnesium glycinate is a chelated compound of magnesium and the amino acid glycine, distinguished by excellent bioavailability and digestive friendliness. Unlike magnesium citrate and oxide, glycinate virtually never causes diarrhea or digestive discomfort. Glycine itself is a calming neurotransmitter, making this form an ideal choice for improving sleep, reducing anxiety, and relieving muscle spasms.
Frequently asked questions about magnesium glycinate
Magnesium glycinate absorbs better than oxide and is much gentler on the digestive tract than citrate. The glycine chelate passes through the intestinal lining more efficiently. It is the best choice for people who experience digestive issues with other magnesium forms.
Yes, it is one of the best magnesium forms for sleep support. Glycine activates NMDA receptors in the brain and lowers body temperature, promoting sleep onset. Studies show 3 g of glycine before bed improves sleep quality — magnesium glycinate delivers both magnesium and glycine simultaneously.
A typical dose is 200-400 mg of elemental magnesium per day. Since glycinate tablets are larger (glycine adds weight), split the dose into two servings daily. Start with a lower dose and gradually increase to find your optimal amount.
Yes, magnesium glycinate is one of the few magnesium forms that can be comfortably taken on an empty stomach since it does not irritate the digestive tract. However, a light meal further improves absorption. Avoid taking it simultaneously with calcium-rich foods, as they compete for absorption.
