Our verdict

A straightforward two-mineral citrate capsule with a large 240-count bottle, suited to general mineral support rather than treating a diagnosed deficiency.

Overview

Each capsule combines 99 mg of potassium with 210 mg of magnesium in citrate form, a combination often used together since both minerals support similar functions. The bottle holds 240 capsules and the formula is unflavored, non-GMO, and gluten free.

Potassium and magnesium citrate are paired here rather than sold as single-mineral products, useful for anyone tracking both intakes without buying two bottles. The 99 mg potassium dose is intentionally modest and sits below FDA labeling thresholds that apply to higher-dose potassium products, so this reads as a maintenance-level amount rather than a therapeutic one.

  • 99 mg potassium, 210 mg magnesium per capsule
  • 240 capsules per bottle
  • Citrate mineral form
  • Non-GMO, gluten free

Who it's for

Fits people who want a combined electrolyte-style supplement for routine mineral intake, such as those on low-sodium diets or with moderate activity levels. Not a substitute for a doctor-directed higher-dose potassium regimen if a real deficiency has been diagnosed.

Pros and cons

Pros
  • Combines potassium and magnesium in one capsule
  • Citrate forms for general absorption
  • Large 240 count bottle
  • Non-GMO and gluten free
Cons
  • Potassium dose is low per capsule
  • Unflavored capsule offers no taste cues

Performance notes

Citrate forms of potassium and magnesium are generally well absorbed and are a common choice for daily supplementation. Because the potassium dose is capped at 99 mg per capsule, multiple capsules would be needed to reach amounts used therapeutically, so check the label against any specific target a doctor has set.
