Thorne Magnesium Glycinate provides an essential mineral – magnesium – to support everything from muscle function to sleep quality. In fact, magnesium is crucial for the whole body to function properly because magnesium is involved in more than 600 of the body's enzymatic reactions.*

But according to World Health Organization statistics, as many as 75% of U.S. adults do not meet the U.S. Food and Drug Administration's recommended daily intake of 420 mg of magnesium. Magnesium deficiency can manifest in many ways, such as inefficient blood sugar metabolism, muscle cramps or soreness, eyelid twitching, fatigue, and poor sleep.*

Features of Thorne Magnesium Glycinate

  • An easy-to-take single-capsule serving size, designed for customizable dosages that fit your daily needs

Why is magnesium important?  

Magnesium, in all its forms, promotes energy production, protein synthesis, and DNA formation. It plays a key role in supporting muscle and nerve function, helping regulate muscle contractions and maintain a steady heartbeat. Magnesium also contributes to bone health and helps manage stress by supporting a healthy nervous system.
