Overview
A vegan potassium chloride capsule delivering 1000mg of potassium per serving in a 90-capsule bottle, formulated for electrolyte balance and heart, muscle and nerve support. Non-GMO and gluten-free, unflavored.
Most drugstore potassium supplements cap out near 99mg a tablet because of FDA labeling limits on that mineral, so a 1000mg-per-serving product like this one likely spreads the dose across multiple capsules rather than one pill delivering the full amount at once. Anyone adding potassium chloride on top of a normal diet, especially with kidney issues or on blood pressure medication, should check with a doctor first since excess potassium carries real cardiac risk.
- 90 vegan capsules per bottle
- 1000mg potassium chloride per serving
- Formulated for electrolyte, heart, muscle and nerve support

Who it's for
Fits people who already know they run low on potassium, such as those on a low-carb or keto diet, athletes with heavy sweat loss, or anyone told by a doctor to add potassium chloride specifically rather than potassium citrate or gluconate. Not a general multivitamin substitute.
Strengths and trade-offs
Drawn from this product's published specifications.
- Vegan, non-GMO and gluten-free formulation
- Delivers a meaningful 1000mg potassium dose per serving
- Unflavored, easy to dose alongside other supplements
- High-dose potassium chloride needs medical oversight, not casual use
- No listed capsule-by-capsule dosing breakdown in the data
- Not suitable for kidney impairment without medical sign-off
Performance notes
Potassium chloride is the same form of potassium used in prescription supplements for documented deficiency, so it is well absorbed, but the dose sits far above what over-the-counter products typically carry in a single tablet. Splitting the 1000mg across the recommended serving of capsules, rather than swallowing a full dose in one go, is the safer way most people take this kind of product.
