Jigsaw Health 's MagSRT® was evaluated in the Scottsdale Magnesium Study (SMS), a placebo-controlled clinical trial of 91 participants.

The study measured serum magnesium, magnesium in red blood cells (RBCs) and symptoms of magnesium deficiency. The results were published in the Journal of the American College of Nutrition (JACN) and the abstract is available on PUBMED.

the "Scottsdale Magnesium Study" is the first peer-reviewed clinical trial of a time-released magnesium supplement versus placebo.

Given that 75% of participants had suboptimal magnesium levels at the start of the study, we were extremely pleased to see a significant increase in serum and RBC magnesium levels and a corresponding reduction in magnesium deficiency symptoms in the MagSRT™ group." Decker Weiss, naturopathic cardiologist and principal investigator at SMS.

The results of the study showed 3 main outcomes of using MagSRT®:

The birth of the Jigsaw Health brand

The Jigsaw Health brand is a family-owned company that manufactures science-based dietary supplements. It was founded in 2005 by Pat Sullivan (father) and Patrick Sullivan Jr. (son). Pat suffered from recurring and chronic health problems for over 30 years such as low energy, sleep problems, gastrointestinal problems, disturbed mood and more. All these difficulties were difficult to diagnose and treat. So Pat decided to find a solution to his health problems through dietary supplements and worked with nutritionists and doctors.

Together with his son Patrick, they created the Jigsaw Health brand, which offers high-quality nutritional supplements. The Jigsaw Health brand focuses mainly on magnesium supplements such as MagSRT®. But there are also excellent products for hydration and regeneration.
