Magnesium
A mineral involved in 600+ enzymatic reactions, including sleep and stress regulation.
Magnesium is an essential mineral cofactor for over 600 enzymatic reactions, including energy production, protein synthesis, DNA repair, and neuromuscular function. It plays a key role in regulating the hypothalamic-pituitary-adrenal (HPA) stress axis and supports GABA receptor function, contributing to sleep quality and stress resilience. Common supplemental forms include magnesium glycinate (calming, well-absorbed), magnesium threonate (crosses blood-brain barrier), magnesium citrate (laxative effect), and magnesium oxide (poorly absorbed). Subclinical deficiency is estimated to affect 50-80% of the population.
