95 out of 100

Potassium Citrate provides potassium for normal electrolyte balance and blood vessel function in a clearly identified form. Its favorable serving cost makes it an economical option for adding potassium.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality100

Potassium citrate is a favorable potassium form. The clearly named form makes comparisons straightforward.

Ingredient Transparency100

Both the potassium amount and form are disclosed. The serving is straightforward to compare with alternatives.

Value For Money100

The serving cost is favorable for a potassium supplement. It offers an economical way to add this nutrient.

Customer Satisfaction93

Customer ratings are very favorable. A very large review base gives that satisfaction pattern broad support.

Product Focus73

The single ingredient supports electrolyte balance and normal blood vessel function, particularly when potassium intake is low. The serving is below the amounts associated with the blood-pressure findings, so a personal response cannot be predicted.

Potassium · 448 mg

Potassium helps regulate vascular tone and sodium balance, with blood-pressure benefits most relevant when habitual intake is low. The declared potassium citrate makes a clear contribution in the saved findings. Its 448 mg per serving is below the daily potassium exposures in the cited trials, so the saved amount finding should not be read as a measured blood-pressure response.
