Overview

Potassium citrate softgels aimed at muscle, heart, and electrolyte support, sold as a 60-count bottle sized for a two-month supply. The form is a softgel rather than a tablet or gummy.

Worth noting: the label lists 1000mg of potassium citrate compound, not necessarily 1000mg of elemental potassium. US over-the-counter potassium supplements are conventionally capped near 99mg of elemental potassium per serving for cardiac safety reasons, so the supplement facts panel is the figure to check rather than the front-label number.

  • 1000mg potassium citrate per softgel
  • 60 softgels, a two-month supply
  • Non-GMO
  • Unflavored softgel form

Who it's for

Adults looking for a softgel-format potassium supplement for muscle, heart, and electrolyte support, particularly those who dislike chalky tablets, are the target here. It isn't the right pick for anyone with kidney disease or on potassium-affecting medication without first confirming the elemental potassium dose with a doctor.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Softgel form for those who dislike chalky tablets
  • 60-count bottle sized as a two-month supply
What to check first
  • Check elemental potassium amount, not just citrate weight
  • Unflavored, no taste-masking data provided

Performance notes

Potassium citrate is a common form used for electrolyte and pH support, and softgels avoid the chalky texture some tablet forms have. Because US OTC potassium supplements are conventionally limited to about 99mg of elemental potassium per serving for safety, a 1000mg potassium citrate softgel is worth double-checking against the supplement facts panel rather than assuming the full figure is elemental potassium.
