Three forms of magnesium (citrate, oxide, succinate) in one capsule for broad coverage. 500mg elemental magnesium at $0.12/serving. Life Extension's research-focused approach delivers value.
This product earns high marks for delivering a meaningful 500mg elemental magnesium dose at exceptional value. The multi-form approach is pragmatic for general deficiency correction. No hype penalty -- Life Extension markets based on research rather than influencers. The formulation score is lower than pure glycinate because oxide has poor bioavailability, but the total dose compensates. Excellent for basic magnesium needs.
Life Extension Magnesium Caps combine magnesium citrate, oxide, and succinate to provide 500mg elemental magnesium per serving. The multi-form approach hedges absorption characteristics -- citrate is well-absorbed, oxide provides high elemental content, and succinate contributes to energy metabolism. While not as targeted as pure glycinate or threonate, the broad-spectrum approach addresses general deficiency effectively. Life Extension is known for research-driven formulation.
| Ingredient | Dose | Verdict |
|---|---|---|
| Magnesium (citrate, oxide, succinate blend) | 500mg elemental | Optimal |
Includes magnesium oxide, which has very poor bioavailability (~4%). The multi-form blend does not disclose the ratio of each form. Not targeted for specific outcomes like sleep (threonate) or relaxation (glycinate). Large capsule size.
