Our assessment
The evidence shows that Thorne Research Magnesium Bisglycinate is a well-formulated supplement for supporting magnesium levels. Our assessment: it provides a highly absorbable form of magnesium that is gentle on the stomach, making it a strong option for daily use. Data on optimal dosing for this specific product is not available, but general guidance applies.
How it works
Think of magnesium as a vital cofactor — it is involved in over 300 biochemical reactions in your body, including muscle relaxation, nerve function, and energy production. The bisglycinate form in this product is bound to the amino acid glycine, which enhances absorption and reduces the likelihood of digestive upset compared to other forms like magnesium oxide [NIH ODS]. This makes it particularly effective for supporting restful sleep and calming the nervous system [NIH ODS].
Safety profile
Data on adverse event reports specific to Thorne Research Magnesium Bisglycinate is not available. However, magnesium supplements in general are considered safe when taken within recommended doses. Common side effects from excessive intake can include diarrhea and gastrointestinal cramping, though the bisglycinate form is less likely to cause these issues [NIH ODS]. Always stay within the daily tolerable upper intake level of 350 mg from supplements to avoid side effects [NIH ODS].
Our recommendation
We recommend Thorne Research Magnesium Bisglycinate for anyone looking to support muscle health, sleep quality, or stress management. Start with one capsule daily, preferably in the evening, and increase gradually as needed. This product is a high-quality choice with excellent bioavailability [NIH ODS].
