Thorne | Magnesium Glycinate, 90 capsules

Formerly: Magnesium Bisglycinate Pills

Magnesium Glycinate supports a calm response to everyday stress and emotional well-being while helping reduce feelings of stress and promote relaxation before bedtime.*

9 out of 10 consumers reported sleeping better and feeling calmer in stressful moments after supplementing with Thorne Magnesium Glycinate, based on a 28-day consumer perception study of 95 participants. Magnesium plays a critical role in promoting muscle relaxation and maintaining a healthy nervous system – both of which are essential for restful, restorative sleep.*

Beyond sleep, magnesium is fundamental to whole-body health. It’s involved in more than 600 enzymatic reactions in the body, influencing everything from energy production and sugar metabolism to cardiovascular and neuromuscular function.*

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.

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.

What did people experience when using Thorne Magnesium Glycinate?

In a 28-day consumer perception study, 95 adults who were not previously supplementing with magnesium added Thorne Magnesium Glycinate to their nightly routine. By the end of the study, participants reported noticeable improvements in sleep, relaxation, and overall well-being.

• 91% experienced improved sleep quality

FAQs

Is Magnesium Glycinate right for me?

Magnesium Glycinate may be a good choice if you’re looking for a highly absorbable form of magnesium that is gentle on the stomach. It’s often recommended for individuals who want to support muscle relaxation, restful sleep, and overall nervous system health. Magnesium plays an important role in helping the body manage stress by promoting a sense of calm.* If you’re unsure whether it’s right for you, consider your health goals and consult with your health-care professional for personalized guidance.

What testing does Thorne complete for Magnesium Glycinate?

We test each ingredient in Magnesium Glycinate for identity, purity, and potency to ensure every ingredient and finished product meet our strict quality standards at the time of manufacture and up to the product’s expiration date. This includes checking for contaminants like heavy metals, pesticides, and harmful microbes. When the product carries the NSF Contents Certified mark, it means it has been third-party tested and certified according to strict standards for quality, safety, and label claims.

What's the difference between magnesium glycinate, magnesium bisglycinate, and magnesium citrate?

Magnesium glycinate and magnesium bisglycinate are terms that are often used interchangeably for the same compound, as both refer to magnesium bound to two glycine molecules. This form tends to be gentle on digestion and supportive of relaxation. Magnesium citrate is a form of magnesium bound to citric acid and is often used for bowel regularity because it draws water into the intestines to keep things moving smoothly. The bisglycinate/glycinate form is typically preferred when the goal is relaxation and nervous system support without gastrointestinal effects.*

When will I see results from Magnesium Glycinate?

Everyone’s body is different, and therefore the timeframe can vary depending on your individual health, lifestyle, and the type of supplement you're taking. Some people notice effects – like muscle relaxation – soon after taking it, especially before bedtime, while for others it may take a few weeks of consistent use.* Supplements work gradually to support long-term health.
