MagSRT®, a time-release Magnesium supplement from Jigsaw Health, was tested vs. placebo in a human clinical trial of 91 people.

MagSRT® is the only time-release magnesium supplement with peer-reviewed clinical trial.  

The results of the Scottsdale Magnesium Study were published by the highly-acclaimed, peer-reviewed Journal of The American College of Nutrition (JACN) in 2018.

Scottsdale Magnesium Study - Serum Magnesium Increased by 22% with MagSRT
Scottsdale Magnesium Study - RBC Magnesium Increased by 30% with MagSRT
Scottsdale Magnesium Study - Magnesium deficiency symptoms decreased by 63% with MagSRT


RESULTS: More than 75% of trial participants presented with suboptimal serum and RBC magnesium status at baseline, while the magnesium status questionnaire predicted 100% of participants to have suboptimal magnesium status. MagSRT® was well tolerated by 91% of magnesium intervention participants. RBC magnesium increased 6% and 30% over 30 and 90 days, respectively, suggesting magnesium absorption and uptake into red blood cells over time. Overall symptomatology, assessed through a magnesium status questionnaire, improved 28% over 30 days and 63% over 90 days.  

CONCLUSION: A standard adult clinical population presented with both qualitative and quantitative evidence of compromised magnesium status at the beginning of the trial. Supplementation with MagSRT®, a timed-release dimagnesium malate supplement containing vitamins B6, B12, and folate, for at least 30 days significantly improved magnesium status symptoms and increased RBC magnesium with minimal gastrointestinal symptoms.
