Life Extension Magnesium Caps deliver a robust 500 mg dose of a triple magnesium complex, combining magnesium oxide, citrate, and succinate. This formulation is designed to maximize the mineral's bioavailability and target multiple health areas, from heart and bone support to nerve function and metabolism. It's an excellent choice for adults looking to fill dietary gaps or address specific health concerns related to magnesium deficiency.

Design-wise, the capsules are vegetarian and off-white in color. The bottle contains 100 capsules, providing a 100-day supply at the recommended serving of one capsule daily.

Buying Guide: Choosing the Right Magnesium Citrate for Heart Health
When selecting a magnesium supplement, consider these key factors to ensure you get the most benefit for your heart and overall wellness.
Form and Absorption
Magnesium citrate is one of the most bioavailable forms, meaning your body absorbs it efficiently. This makes it ideal for supporting heart function and muscle relaxation. The magnesium for cardiovascular health article explains why citrate outperforms other forms like oxide.
Both Pure Encapsulations Magnesium (Citrate) and Life Extension Magnesium Caps, 500 mg use citrate in their formulas, but Life Extension adds oxide and succinate for a broader profile. For pure citrate, Pure Encapsulations is the straightforward choice.
Purity and Additives
If you have sensitivities, look for supplements free from common allergens, artificial ingredients, and GMOs. Pure Encapsulations prides itself on a clean formulation, while Life Extension also offers non-GMO, gluten-free options. Always check the label for unnecessary fillers that could interfere with absorption.
Dosage and Potency
Heart health benefits often require a consistent daily dose of 200 to 400 mg of elemental magnesium. Pure Encapsulations provides 150 mg per capsule (as citrate), while Life Extension delivers 500 mg total (with 160 mg from citrate plus other forms). Adjust based on your dietary intake and tolerance. For men specifically, our magnesium for men guide offers tailored advice.
Additional Benefits
Beyond the heart, magnesium citrate supports bone density, energy metabolism, and restful sleep. The NeuroPrime supplement is designed for brain health, but it also contains magnesium to aid cognitive function—a nice bonus if you want dual support.

Both are trusted choices for maintaining heart health in 2026.
Frequently Asked Questions
How much magnesium citrate should I take for heart health?

Is magnesium citrate better than magnesium oxide for the heart?
Yes, magnesium citrate is more easily absorbed than oxide, making it more effective for raising magnesium levels and supporting cardiovascular function. Oxide is cheaper but often causes digestive discomfort.
