Description

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.*

FAQs
Frequently asked question

Is Thorne Magnesium Glycinate worth buying compared to other magnesium supplements?

Thorne Magnesium Glycinate stands out because it uses a highly bioavailable form of magnesium that is gentle on the stomach and well-absorbed by the body. Many cheaper supplements use magnesium oxide, which has poor absorption rates. Thorne is also NSF Certified for Sport, meaning it meets strict quality and purity standards. If you want a reliable, effective magnesium supplement backed by science, this is a strong choice.

Where can I buy Thorne Magnesium Glycinate and what is the return policy?

Thorne Magnesium Glycinate is available directly on this page. We offer a satisfaction-backed return policy, so if you are not happy with your purchase, contact our support team within the return window for assistance. Buying from an authorized retailer ensures you receive a genuine product with full manufacturer quality assurance and freshness guarantees.

What is magnesium glycinate and how is it different from regular magnesium?

Magnesium glycinate is magnesium bonded to the amino acid glycine. This combination improves absorption compared to common forms like magnesium oxide and is much gentler on the digestive system. It is less likely to cause the laxative effect associated with other magnesium types, making it ideal for daily use and for people with sensitive stomachs.

What are the main benefits of taking Magnesium Glycinate?

Magnesium supports over 600 enzymatic reactions in the body. Key benefits include improved muscle function and recovery, better sleep quality, reduced stress and anxiety, healthy bone density, and normal nerve function. Since up to 75% of U.S. adults do not get enough magnesium daily, supplementing can help fill a critical nutritional gap for overall wellness.

How much magnesium should I take daily and when is the best time to take it?

The FDA recommends 420 mg of magnesium daily for adults. Many people find taking magnesium glycinate in the evening beneficial because of its calming properties and support for sleep quality. Always follow the dosage instructions on the product label and consult your healthcare provider if you have existing health conditions or take medications.

Can magnesium glycinate help with sleep and stress?

Yes. Magnesium plays a key role in regulating the nervous system and supporting the production of calming neurotransmitters. Many users report improved sleep quality and reduced feelings of stress and tension when supplementing with magnesium glycinate regularly. The glycine component also has its own calming properties, making this form particularly well-suited for relaxation and nighttime use.
