Overview
Amazon Basics offers potassium capsules dosed at 99 mg each, the standard strength for over the counter potassium supplements in the US, packaged 250 to a bottle for extended daily use.
99 mg is the common ceiling regulators allow for OTC potassium products, so this listing sits at the typical dose rather than an unusually high or low one. The 250 count size means it lasts roughly eight months at one capsule daily, longer than most single nutrient bottles on the shelf.
- 99 mg potassium per capsule
- 250 capsules per bottle
- Standard OTC dosage strength
- Amazon Basics brand
Who it's for
Good for someone who wants a plain, single ingredient potassium capsule at the standard 99 mg dose and prefers a large count to avoid reordering often. Less useful for anyone told by a doctor to take a higher potassium dose, since 99 mg per capsule is the regulatory maximum for this category.
Pros and cons
- Large 250 count supply
- Standard 99 mg OTC dose
- Amazon Basics house brand pricing

- No flavor or coating detail given

Performance notes
At 250 capsules and one per day, this bottle covers around eight months before needing a refill, which reduces how often it needs reordering compared to smaller 60 or 90 count bottles. With 1,000 monthly purchases, it is a high volume, repeat buy listing.
