Overview

Now Foods' magnesium glycinate capsules pair the glycinate chelate form with BioPerine black pepper extract for absorption, 180 vegetarian capsules per bottle, unflavored, aimed at nervous system support.

Glycinate is one of the gentler magnesium chelates on the stomach compared to oxide or citrate, and Now's inclusion of BioPerine is a bioavailability aid rather than a dose booster. This is a maintenance-dose capsule for people building magnesium into a daily stack, not a fast-acting cramp or sleep remedy.

  • 180 vegetarian capsules per bottle
  • Magnesium glycinate with BioPerine
  • Unflavored
  • Vegan, dairy/egg/nut/soy free

Who it's for

Suits adults building a daily magnesium routine who prefer capsules over powders and want a vegan, allergen-free option free of dairy, egg, nuts and soy. Not aimed at anyone needing a specific elemental magnesium dose without checking the label first, since glycinate delivers less elemental magnesium per capsule than oxide forms.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Vegan and vegetarian capsule form
  • Free of dairy, egg, nut and soy allergens
  • 180-count bottle covers months of daily use
  • Unflavored, easy to fit into a routine
What to check first
  • No listed elemental magnesium amount per capsule in the data
  • Capsule form is slower to take effect than powder or liquid

Performance notes

Magnesium glycinate is chelated to glycine, which tends to be better tolerated by the digestive system than magnesium oxide. BioPerine is included to support absorption of the compound rather than to add magnesium itself, so effects build with consistent daily use rather than a single dose.
