Jigsaw’s Mag SRT B-Free combines the highly absorbable form of magnesium, dimagnesium malate from Albion, with their proprietary Sustained Release Technology (SRT), without the B vitamins. SRT slows down the release of magnesium to spread it out over eight hours. This allows for maximum absorption, while eliminating the digestive discomfort often caused by other high-dose magnesium supplements.

Each 4 tablets contains: Vitamin C (as Ascorbyl Palmitate) 10mg,  Magnesium (as Dimagnesium Malate) 500mg.
Other ingredients: Microcrystaline cellulose & Hydroxylpropyl Cellulose (Plant-based insoluble fiber used to achieve Sustained Release Technology) L-Leucine (essential amino acid used as lubricant), Silicone Dioxide (anti-caking agent),  Clear coating (Hydroxypropylmethylcellulose and sunflower), Microcrystaline wax (for easier swallowing).

Adults take 4 tablets daily, as a dietary supplement. Doses can be divided, or taken as directed by a healthcare practitioner.
