Overview

Now Foods magnesium glycinate pairs elemental magnesium with the amino acid glycine in a 240 tablet bottle, a form often chosen for easier digestion than magnesium oxide. It suits anyone adding a daily magnesium habit for muscle and nerve support.

Glycinate is one of several magnesium forms sold on Amazon, and Now Foods is a long running supplement brand rather than a newer arrival. The 240 count size runs several months at a typical one or two tablet daily dose, which lowers the per dose cost versus smaller bottles.

  • 240 tablets per bottle
  • Magnesium glycinate form
  • Non-GMO
  • Supports muscle and nerve function

Who it's for

Fits someone who wants a daily magnesium supplement without splitting pills or reordering monthly. Less useful for anyone who needs a liquid or powder form, or who is targeting a specific therapeutic dose set by a doctor.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Large 240 tablet count
  • Glycinate form is easier on digestion
What to check first
  • Tablet form only, no capsule or powder option
  • No stated dose per serving in the data provided

Performance notes

Magnesium glycinate is generally better tolerated than cheaper oxide forms because the glycine binding reduces the laxative effect some people get from magnesium at higher doses. Tablet count and dosing schedule determine how many months a 240 count bottle actually covers.
