Overview
Life Extension Potassium with Extend-Release Magnesium combines two minerals in a single capsule aimed at heart health and blood pressure support, sold 60 to a bottle in a non-GMO, vegetarian, gluten free formula.
Pairing potassium with an extended-release magnesium is meant to support blood pressure and vascular health together rather than dosing either mineral alone. The listing does not break out the milligram amount of each mineral individually, so exact dosing per capsule is not confirmed here.
- Potassium plus extend-release magnesium
- Blood pressure and vascular support
- Non-GMO, vegetarian, gluten free
- 60 capsules
Who it's for
People focused on blood pressure and cardiovascular support who want potassium and magnesium combined in one capsule. It is not a substitute for prescribed blood pressure medication.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines potassium and magnesium in one capsule
- Extended-release magnesium format
- Non-GMO, vegetarian and gluten free
- No individual milligram breakdown per mineral listed
- 60 capsules may be a short supply depending on daily dose
Performance notes
The extend-release format is designed to release magnesium gradually alongside potassium, positioned to support blood pressure, bone strength, vascular health and mood together rather than isolate a single benefit.
