About Magnesium

Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body. It supports muscle and nerve function, sleep quality, and energy production.

Common forms include glycinate (calming, well-absorbed), citrate (bioavailable, gentle laxative effect), and threonate (crosses the blood-brain barrier for cognitive support).

Why Supplement with Magnesium?

Up to 50% of the population may not meet the recommended daily intake of magnesium through diet alone. Stress, alcohol, and certain medications can further deplete levels.

Magnesium supports over 300 biochemical reactions, including protein synthesis, blood sugar control, and blood pressure regulation. Many people report improved sleep quality when supplementing with magnesium glycinate before bed.

Choosing the Right Magnesium Form

Magnesium glycinate is ideal for relaxation and sleep. Citrate works well for general supplementation and digestive regularity. Threonate (Magtein) is researched for memory and cognitive function. Avoid magnesium oxide for supplementation as it has poor absorption.
