Evening or before bed

Take magnesium glycinate in the evening, ideally 30 to 60 minutes before bed.

Magnesium glycinate is the calming, sleep-friendly form: it relaxes muscle and quiets an over-active nervous system, and the glycine it is bound to is itself mildly sedating. Because it is gentle and non-laxative, it does not need food and is easy to take last thing at night.

How to take it
