10 Best Potassium Supplements 2025 in the United States

Nutricost Potassium Citrate capsules provide potassium in the form of potassium citrate, which is known for good absorption compared to some other potassium types. Each capsule contains 99mg of elemental potassium, a modest dose suitable for those needing a mild supplement but potentially low for users with higher potassium requirements. The product comes with two bottles, each containing 500 capsules, offering a large quantity that could last a long time.

These capsules are unflavored and easy to swallow, convenient for daily use. Nutricost emphasizes quality by producing these supplements in an FDA-registered, GMP-compliant facility. They are third-party tested, non-GMO, gluten-free, and soy-free, catering to users with dietary sensitivities. The label warns not to exceed the recommended dosage, reflecting the need to be cautious with potassium intake as excessive amounts can be harmful.

This product offers a reliable and clean option for individuals seeking a straightforward potassium citrate source from a reputable brand, especially those wanting a large supply without extra additives. Users looking for higher doses or additional supportive ingredients like magnesium or vitamin B6 might find it limited.

The Life Extension 99mg Potassium with Extend-Release Magnesium supplement combines potassium with magnesium, two minerals that support heart health and help the body manage excess sodium. The potassium dosage at 99mg is moderate, which is suitable for daily supplementation but may be lower than some other products if you need higher potassium intake. The inclusion of magnesium, especially in an extend-release form, helps improve absorption and provides sustained benefits throughout the day.

These capsules are vegetarian, vegan, gluten-free, and non-GMO, making them a good choice if you have dietary restrictions or preferences. The capsules are easy to take and unflavored, which is convenient for most adults. Life Extension is a well-known brand with over 40 years of experience in supplements, adding a level of trust and quality assurance.

The relatively low potassium dosage per capsule means those needing higher amounts might require multiple capsules or a different product. Also, if you are looking specifically for a high-dose potassium supplement without magnesium, this might not be the best fit. This product suits adults seeking a balanced daily supplement that supports overall mineral balance with gentle absorption, especially if you appreciate the added benefit of magnesium and prefer vegetarian-friendly options.
