Quick Facts

Who NOW Potassium Citrate Is For

• Active people and athletes who lose potassium through sweat and want to replace it
• People on low-sodium diets, who often need more potassium to balance electrolytes
• Adults eating limited fruits and vegetables who want a basic daily potassium top-up
• People who get muscle cramps and want to support electrolyte balance alongside magnesium
• People wanting the well-absorbed citrate form rather than basic potassium chloride

Who this product is NOT for: If you have kidney disease, take blood pressure medications (especially ACE inhibitors or potassium-sparing diuretics), or have any heart condition, talk to your healthcare practitioner before supplementing with potassium. Excess potassium can be dangerous in these situations. Most healthy adults get enough potassium from fruits, vegetables, and dairy.

Vitamart's Take

Potassium is one of those minerals where supplementing is more limited than people expect. Canadian regulations cap most potassium supplements at 99 mg per capsule — a fraction of the 3,400 mg most adults need daily. That cap exists because excess potassium can be dangerous, especially for people with kidney or heart conditions. So think of potassium supplements as a small daily top-up, not a replacement for food sources (bananas, potatoes, leafy greens, beans, avocados). NOW Potassium Citrate is a quality basic option in the well-absorbed citrate form.

How NOW Potassium Citrate Compares

Potassium Citrate vs Potassium Chloride

Potassium Citrate: Well-absorbed form, gentler on the stomach. Most-recommended supplemental form.
Potassium Chloride: Often used in salt substitutes. Less commonly used as a standalone supplement.

Potassium Citrate vs Potassium-Rich Foods

Potassium Citrate: Convenient 99 mg per capsule top-up.
Potassium-Rich Foods: One banana has about 422 mg potassium, a baked potato about 925 mg. Food is the most effective way to get the 3,400 mg daily requirement.

What Does Potassium Do?

Potassium is one of the body's main electrolyte minerals. It works with sodium, magnesium, and calcium to maintain:

• Fluid balance inside and outside cells
• Nerve function — every nerve signal involves potassium
• Muscle function — including the heart muscle
• Acid-base balance in the body

The Health Canada recommended daily intake is 3,400 mg for adult men and 2,600 mg for adult women — most of which should come from food (fruits, vegetables, dairy, beans). Supplements can fill small gaps but shouldn't replace dietary potassium.

How To Use

Adults: Take as directed on the label, with food, or as recommended by your healthcare practitioner.

Talk to a healthcare practitioner before use if you have kidney disease, take blood pressure or heart medications (especially ACE inhibitors, ARBs, or potassium-sparing diuretics), have a heart condition, are pregnant or breastfeeding, or take any medication. Excess potassium can be harmful in these situations.
