Magnesium Caps
Life Extension offers the best balance of cost and efficacy, providing a 500mg blend of magnesium oxide, citrate, and succinate. While oxide is often criticized, research suggests it is effective in a blend for maintaining long-term systemic levels at a fraction of the cost.
Ingredients & Purity
A blend of Magnesium Oxide, Citrate, and Succinate. Includes 500mg elemental magnesium per capsule.
Scientific Evidence
The combination of fast-acting citrate and slow-release oxide provides a sustained magnesium elevation in the blood.
Brand Transparency
Life Extension is highly transparent; customers can enter a lot number on their site to receive a COA.
Value Assessment
Unbeatable value at approximately $0.10 per 500mg capsule, making it the most accessible high-quality option.
Why Not Alternatives?
Cheaper drugstore brands like Nature Made often use only low-quality oxide without the citrate/succinate carriers found here. Life Extension also provides a Certificate of Analysis (COA) for every batch, which most budget brands refuse to do.
