Analysis

MagSRT uses a slow-release technology to help the magnesium absorb over several hours rather than all at once. This helps keep your mineral levels steady and significantly reduces the chance of having a laxative effect. The malate form is particularly helpful for supporting ATP production and physical energy levels.

This is a great option for people who are sensitive to regular magnesium supplements but still need a meaningful dose. It works well for supporting muscles and the nervous system without causing the bathroom trips common with other pills. If you want a similar malate benefit without the slow-release feature, Source Naturals (193970) offers a standard tablet.

Pros

  • Patented slow-release technology
  • Highly bioavailable malate form
  • Excellent digestive tolerance
  • Maintains steady mineral levels
  • Supports energy and muscle health

Cons

  • Premium price point
  • Tablets are somewhat large
  • B-Free version lacks helpful cofactors like B6

Warnings

  • Do not crush or chew the slow-release tablets
  • Check with a professional if you have kidney issues
