Overview
NOW Foods' Magnesium Glycinate tablet provides 100mg of magnesium in the glycinate form per serving, packaged 180 tablets to a bottle and listed as a highly absorbable form.
At 100mg per tablet this is a lower per-dose amount than the 400mg glycinate tablets elsewhere in this category, so multiple tablets a day may be needed to reach a typical target intake; the 180-count bottle offsets that with a longer supply. Choosing glycinate over oxide is generally about tolerability rather than potency.

Who it's for
Buyers who want to control magnesium dosing in smaller 100mg increments, or who take magnesium alongside other supplements and want flexibility per dose.
Strengths and trade-offs
Drawn from this product's published specifications.
- 100mg magnesium glycinate per tablet for flexible dosing
- 180-tablet bottle provides a long supply
- Glycinate form generally easier on digestion than oxide
- Lower per-tablet dose means multiple tablets needed for a higher target
- No allergen or diet certification data provided
Performance notes
Magnesium glycinate is chelated to glycine for easier gut tolerance, and at 100mg per tablet this allows finer control over total daily intake, useful for people titrating up slowly or combining it with magnesium from other sources.
