Magnesium is super important for over 300 enzymatic functions in the body. It is the number one mineral most people are deficient in. It is especially important for combating stress, muscle recovery, and the production of GABA which is necessary for the body to be able to relax, sleep and feel less anxious. Magnesium helps support healthy blood pressure levels, balanced hormones and enables us to feel relaxed when we need to. A deficiency will contribute to a racing mind, problems sleeping, leg and muscle cramps and issues with irritability. Magnesium can be taken with or without meals or for best help sleeping take in the evening. I use magnesium citrate capsules.. If you tend towards loose stools consider taking magnesium glycinate. CALM is a great powdered form of magnesium that can be taken as a tea before bed. Very good for kids and adults.
