Overview
Life Extension Magnesium Caps combine three forms, oxide, citrate, and succinate, at 500mg per dose in a vegetarian capsule, positioned around heart health, bone strength, and general metabolism support.
Magnesium oxide is inexpensive but less bioavailable on its own, so pairing it with citrate and succinate is a way to balance cost and absorption within one formula. At 500mg total this sits above what many single-nutrient magnesium products offer, worth comparing against your existing supplement stack before adding it in.
- 500mg per serving
- Oxide, citrate, and succinate blend
- Vegetarian capsules
- 100 count
Who it's for
Fits people looking for a higher dose, multi-form magnesium capsule from a longer-established supplement brand, particularly vegetarians since the capsules are formulated for that diet. Less suited to anyone who wants a single, clearly defined magnesium form at a lower dose.
Pros and cons
- 500mg magnesium from three combined forms
- Vegetarian and gluten free capsules
- 100 count bottle
- Positioned for heart and bone health
- Higher dose than many single-form magnesium products
- Includes magnesium oxide, which absorbs less readily than citrate alone
Performance notes
Blending magnesium oxide with citrate and succinate is meant to combine oxide's higher elemental magnesium content with the better absorption profile of citrate and succinate. Magnesium itself supports heart rhythm, bone density, and general metabolic function, which is what the whole-body health framing on the label points to.
