What Is Magnesium Glycinate?

Magnesium glycinate is a nutritional supplement made when magnesium, an essential mineral your body needs, is bound to an amino acid called glycine. This special pairing helps your body absorb the magnesium easily and tends to be gentle on the stomach compared with other forms of magnesium supplements. (Healthline)

What Is It Good For?

Better Sleep

One recent clinical trial found that adults taking magnesium bisglycinate (another name for magnesium glycinate) experienced a modest improvement in insomnia symptoms compared with a placebo. (PMC)

Relaxation & Stress Support

Magnesium helps regulate key brain chemicals that calm your nervous system. Because glycine itself is also relaxing, this combo may support stress resilience and mood, research is still growing in this regard. (juniperhealth.com)

Getting enough magnesium is linked with healthier sleep, balanced stress responses, and support for metabolic functions like blood sugar and blood pressure. (Healthline)
