Overview
A 500mg magnesium complex capsule blending oxide, citrate and glycinate forms, packed 240 to a bottle and labeled gluten free and non-GMO. Aimed at people who want one capsule covering multiple magnesium sources rather than shopping for a single form.
Nutricost leans on volume here, 240 capsules is enough for months of daily use at a lower per-capsule cost than boutique single-form magnesium products. Blending oxide with citrate and glycinate spreads the dose across a cheaper, less bioavailable form and two better-absorbed ones, a middle-ground approach rather than a specialized sleep or muscle-recovery formula. The exact ratio between the three forms per capsule is not broken out in this data.
- 500mg magnesium complex
- Oxide, citrate and glycinate blend
- 240 capsules
- Gluten free and non-GMO
Who it's for
People who want a large, economical supply of magnesium and are not chasing one specific form for a targeted use like sleep. Not the pick for someone who specifically wants a glycinate-only or citrate-only product for a particular reason.
Strengths and trade-offs
Drawn from this product's published specifications.
- 240 capsules per bottle
- Three magnesium forms combined in one capsule
- Gluten free and non-GMO
- Ratio of oxide to citrate to glycinate per capsule is not stated
- No information on capsule shell or coating
Performance notes
Combining oxide, citrate and glycinate means part of each dose comes from the cheaper, less bioavailable oxide form while citrate and glycinate contribute better-absorbed magnesium, a blend that balances cost against absorption rather than maximizing either one.
