Potassium Chloride 365 mg by NOW

If your Potassium on a CMP/BMP tends to run low or low‑normal, potassium chloride is a straightforward way to top up. It’s useful during low‑carb phases, heavy sweating, frequent sauna use, or long training blocks when you’re losing salt and water and feel cramp‑prone or fatigued. People on thiazide or loop diuretics often need more potassium, but should coordinate with their prescriber. If your level is meaningfully low or you have kidney issues, get clinician guidance rather than self‑treat.

Potassium is the main positive ion inside your cells, and it sets the electrical charge that lets nerves fire and muscles contract. The chloride here pairs with potassium to replace chloride losses from sweating or diuretics, helping maintain acid‑base balance (your body’s pH control). When potassium intake improves, many people notice steadier energy and fewer muscle cramps; blood pressure can edge down in salt‑sensitive adults. If your Magnesium is low, repletion is harder, so check that lab too.

Mix 1/8 teaspoon (365 mg potassium) with food and at least 8 oz of water, one to three times daily as tolerated. Spreading doses reduces stomach upset and smooths blood level swings; most see changes on labs within days to a week. This is a practical dose for maintenance. For established deficiency or ongoing diuretic therapy, your clinician may target higher total daily potassium using diet plus supplements and will recheck Potassium on follow‑up labs.

Skip over‑the‑counter potassium if you have kidney disease, poorly controlled diabetes with low kidney function, or Addison’s disease, unless your clinician directs it. Drugs that raise potassium can turn a normal dose into too much: ACE inhibitors, ARBs, aliskiren, potassium‑sparing diuretics (spironolactone, eplerenone, amiloride), NSAIDs, trimethoprim, and cyclosporine. Take with plenty of water to reduce stomach irritation, and avoid combining with salt substitutes that also contain potassium chloride.
