What makes Magnesium w/SRT® so special?

Jigsaw MagSRT® is uniquely formulated to combine Dimagnesium Malate, supporting active B-vitamins, and our proprietary Sustained Release Technology (SRT).

"Why use Dimagnesium Malate?"

Dimagnesium malate is formed when 2 ions of magnesium are attached to a molecule of malic acid (an organic compound found in fruits and vegetables, especially apples).

And, the bond between magnesium and malic acid is weak, allowing it to be readily soluble in the body. Therefore, making it bioavailable and easily absorbed.

Additionally, malic acid has these added benefits:

  • Supports energy production.*
  • Promotes healthy relaxed muscle tone.*
  • Aids in metal chelation.*

"Why do you include Vitamin B6, Folate, and Vitamin B12?"

We include Vitamin B6 in its active form, P5P (Pyridoxal-5-Phosphate), because it works synergistically with magnesium to promote relaxed muscles and nerves.

Quatrefolic® (5-MTHF, or folate) is an important co-factor to P5P and greatly improves magnesium's function supporting healthy muscular tone, energy, mood, calmness, and sleep.

We include the active form of Vitamin B12, methylcobalamin because it contributes to the effectiveness of magnesium and is a necessary cofactor for your body's ability to properly methylate.

"What is SRT and why is it important?"

Jigsaw's proprietary Sustained Release Technology (SRT) is the main differentiator between our product and any other on the market...

Instead of magnesium being dumped into your system all once, SRT slows down the release of magnesium over 6-8 hours allowing maximum absorption...without the laxative side effect that high doses of other magnesium supplements can cause.*

Because of MagSRT® effectiveness and quality, it has been voted as a Best Magnesium Supplement of 2021 by both Health Cares and Parade.
