Overview
This potassium chloride tablet supplies 99 mg of potassium per serving across a 365-count bottle, marketed as a one-year supply for electrolyte and fluid balance support and labeled non-GMO.
At 99 mg per serving, this sits well under the FDA-set threshold that would require the product to be sold in smaller packaging, so the dose per tablet is intentionally modest rather than a high-strength potassium product. The 365-count sizing is built around a once-daily habit for a full year rather than higher or split dosing.
- 99 mg potassium per serving
- 365 tablets, a one-year supply at one a day
- Formulated to be gentle on digestion
- Non-GMO
Who it's for
Fits someone wanting a low-dose, daily potassium tablet as part of general electrolyte support over a long stretch of time. Not suited to anyone who has been advised to take a higher-dose potassium supplement, since 99 mg per serving is a modest amount relative to daily potassium needs.
Strengths and trade-offs
Drawn from this product's published specifications.
- 365-count bottle covers a full year at one tablet daily
- Low per-serving dose formulated to be gentle on digestion
- 99 mg per serving is a modest dose relative to total daily potassium needs
- Not positioned as a high-strength potassium product for significant deficiency
Performance notes
Potassium chloride tablets like this work by adding a small, consistent daily amount of potassium to support the electrolyte and fluid balance role potassium plays in the body, rather than delivering a therapeutic dose. The listing notes it is formulated to be gentle on digestion, which is a common consideration with potassium supplements since larger doses can cause stomach upset in some people.
