Does magnesium lower cortisol?

Yes, magnesium helps lower cortisol by calming the stress response system, regulating hormones, and promoting relaxation and better sleep, with studies showing supplementation reduces urinary cortisol excretion, especially in stressed individuals. Chronic stress depletes magnesium, creating a cycle where magnesium deficiency can increase stress, and supplementation helps break this by supporting the HPA axis (Hypothalamic-Pituitary-Adrenal axis) and moderating cortisol levels throughout the day.

What type of magnesium reduces cortisol?

For reducing cortisol and promoting relaxation, Magnesium Glycinate (or Bisglycinate) is highly recommended due to glycine's calming effects and high absorption, while Magnesium L-Threonate is excellent for brain health and stress, and Magnesium Taurate also supports relaxation, making them top choices for managing stress hormones.
 

Which supplement reduces cortisol the most?
