Analysis

Magnesium bisglycinate is highly regarded for being very gentle on the stomach while reaching muscle and nerve tissues effectively. This formula provides 400mg of the mineral in a form that the body can use quickly to support the nervous system. It is an excellent choice for people who find that other types of magnesium cause digestive issues.

Because it is chelated with glycine, it may also contribute to a sense of calm and better rest. This single-ingredient capsule focuses entirely on providing a high-quality mineral source without any unnecessary fillers. For a more affordable option that still includes some chelated magnesium, the Solgar blend (162077) is an effective alternative.

Pros

  • Highly absorbable bisglycinate form
  • Exceptional digestive tolerance
  • Supports nervous system calm
  • Helpful for sleep and relaxation
  • Clean, simple capsule formula

Cons

  • More expensive than citrate or oxide
  • Requires taking multiple capsules for full dose
  • Lower elemental magnesium per pill

Warnings

  • Monitor for excessive drowsiness if taken during the day
