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

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.
