Overview
Nutricost's magnesium citrate capsules deliver 420mg per serving from a 240 veggie capsule bottle, working out to 60 servings. The formula is gluten free, non-GMO and vegetarian friendly.
Magnesium citrate is the specific compound form used here, distinct from magnesium oxide or glycinate found in other magnesium products, and the 240 capsule count spread over 60 servings implies a multi-capsule serving rather than one capsule a day.
- 420mg magnesium citrate per serving
- 240 veggie capsules, 60 servings
- Gluten free
- Vegetarian friendly
Who it's for
Buyers looking for a magnesium citrate supplement in vegetarian capsule form with a large 60 serving supply. Not the pick for someone who specifically wants a different magnesium compound, such as glycinate, for gentler dosing.
Strengths and trade-offs
Drawn from this product's published specifications.
- Large 240 capsule bottle, 60 servings
- Magnesium citrate, a well-known compound form
- Gluten free and vegetarian friendly
- Serving size spans multiple capsules, not a single one
- No reviews are available to confirm digestive tolerance
Performance notes
With 240 capsules delivering 60 servings, each serving appears to be multiple capsules taken together rather than a single daily capsule, which buyers should account for when estimating how long the bottle lasts.
