What is Potassium?

Potassium is a Mineral supplement available in 1 form.

Not all forms of Potassium are equal. The form you choose determines how much Potassium actually reaches your tissues, and the difference between the best and worst forms can be substantial. Potassium citrate is an organic, alkalizing potassium salt with superior gastrointestinal tolerance compared to potassium chloride, while also providing citrate anions that support healthy urine pH and kidney health. Research supports potassium citrate for promoting healthy blood pressure regulation, muscle function, and electrolyte balance.

Forms of Potassium Compared

Potassium (as Potassium Citrate) Preferred (Preferred Form) has a bioavailability rating of good absorption.

What the Research Shows

Potassium citrate provides highly bioavailable potassium with alkalizing citrate carrier. Research demonstrates potassium supplementation supports blood pressure management, with meta-analyses showing clinically meaningful reductions. The citrate form provides additional benefits for kidney stone prevention via urinary citrate elevation. Most adults consume inadequate potassium relative to the 4,700mg AI.

3-year double-blind RCT (n=57); potassium citrate raised urinary citrate and pH and cut stone formation rate vs placebo. PMID: 8230497
24-month double-blind RCT (n=201); potassium citrate 60 mEq/day increased lumbar spine bone density vs placebo in healthy older adults. PMID: 23162100
12-month double-blind RCT (n=83); potassium citrate decreased bone-resorption markers in postmenopausal women with osteopenia. PMID: 26401577

How to Choose the Right Form

Potassium (as Potassium Citrate) is classified as Preferred Form by FormulaForge — our top recommendation for Potassium. It carries a bioavailability rating of good absorption, meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.

When choosing a Potassium supplement, read the label for the specific form name — that is what determines how much you actually absorb. Preferred Forms have the strongest research-backed evidence for efficient absorption.

Other forms may be appropriate depending on individual goals, cost considerations, and your healthcare provider’s guidance. The best form for you depends on your specific health needs.
