10 Best Potassium Supplements 2025 in the United States

The Life Enhancement Potassium Supplement offers 1020 mg of potassium per serving in the form of potassium bicarbonate, which is known for its high absorption rate. This makes it easier for the body to utilize the mineral effectively. Each bottle contains 240 veggie capsules, making it a convenient option for daily supplementation. With a dosage of 510 mg per capsule, it provides a significant portion of the recommended daily intake of potassium, which is beneficial for those who might not get enough from their diet alone. The capsules contain less than 1% Magnesium Stearate, which is a plus for those looking to minimize additional ingredients.

The product is manufactured by Life Enhancement, a brand with over 25 years of experience in the supplement industry, adding to its credibility. One of the strengths of this product is its ease of use, as capsules are generally easier to swallow compared to tablets or powders. However, it's worth noting that those who prefer flavored supplements might find this product lacking in taste variety, as it is offered in a 'Potassium Basics' flavor. Additionally, while potassium bicarbonate is effective, some users might prefer other forms of potassium depending on their specific health needs or preferences.

The product's long availability since 2011 and its solid brand reputation are definite positives. This supplement is well-suited for individuals seeking to improve their potassium intake through a reliable and straightforward capsule form.

NOW Foods Supplements offers a potassium citrate supplement with a dosage of 99 mg per capsule, designed to support electrolyte balance and normal pH levels.

The recommended dosage is flexible, allowing for 1 to 5 capsules daily based on individual needs, which provides a lot of versatility for different users.

Additionally, the product comes in a simple capsule form, making it easy to incorporate into daily routines. The fact that it is packaged by a family-owned company with a long-standing reputation since 1968 adds to its credibility. On the downside, the product might not cater well to those who prefer flavored supplements, as it is unflavored.

Furthermore, those needing higher doses of potassium might find the 99 mg per capsule to be on the lower side, requiring them to take multiple capsules to meet their needs. Nevertheless, with 180 capsules per bottle, it offers a good supply for a reasonable duration. Lastly, the brand NOW Foods is well-regarded in the health and wellness industry, which can assure customers about the quality and reliability of the product.

The product's manufacturing in the USA and the availability of a Certificate of Analysis add to its credibility. This potassium and magnesium supplement is well-suited for individuals focused on cardiovascular health and seeking a reputable product that aligns with vegetarian and gluten-free diets.
