Overview

NOW Foods Potassium Citrate provides 99mg of potassium per capsule in the highly bioavailable citrate form. Potassium is the third most abundant mineral in the body and is critical for blood pressure regulation, muscle contraction, nerve signaling, and heart rhythm. The 99mg dose per capsule is the FDA-mandated maximum for dietary supplements (due to safety concerns with high single doses), though the daily adequate intake is 2600-3400mg. Most Americans get only about 50% of their daily potassium needs from diet alone, making supplementation common.

Our Verdict

8.0/10 — Very Good

NOW Potassium Citrate is the reliable budget choice for potassium supplementation. The 99mg FDA-limited dose means it's a supplement to dietary potassium, not a replacement. At this price, it's worth adding to your stack if you're on a low-carb diet or don't eat enough potassium-rich foods.
