Overview

NOW Potassium Citrate provides 99mg of potassium in the highly bioavailable citrate form. The 99mg dose is the FDA-regulated maximum for dietary supplement capsules/tablets. Potassium is essential for blood pressure regulation, muscle contraction, nerve function, and fluid balance. Most Americans consume only 50-60% of the adequate intake (4700mg/day). The 180-capsule count provides a 6-month supply.

  • Citrate form — highly bioavailable
  • 22,400+ reviews, 4.6 stars
  • Essential electrolyte
  • $0.06/day — budget-friendly

What Could Be Better

  • 99mg is only 2% of adequate intake
  • FDA limits capsule dose to 99mg
  • Need dietary potassium too
  • Single mineral only

Who Is This For?

Best For

  • Potassium supplementation
  • Blood pressure support
  • Electrolyte balance
  • Those on potassium-depleting medications

Our Verdict

8.2/10 — Very Good

The essential potassium supplement. 99mg is the FDA-regulated max per capsule — supplements are meant to complement dietary potassium, not replace it.
