Klean Electrolytes by Klean Athlete

Hot-weather runners, indoor cyclists, and keto or low-carb athletes who urinate more sodium than usual are the people who notice these electrolyte capsules. If you cramp late in workouts or finish with a headache and low energy, light replacement helps. Check labs like Serum Sodium, Serum Potassium, and Magnesium, RBC if you’re curious whether your baseline is low. The dose here is conservative, best for light sweaters or shorter sessions; heavy salt sweaters will usually need more sodium per hour than one capsule provides.

Sodium and chloride steer fluid balance between blood and tissues, which is why replacing them helps maintain plasma volume and steady heart rate in heat. Potassium and magnesium support nerve firing and muscle contraction, so low levels show up as cramping or weak finishing kicks. This formula adds vitamin B6 as pyridoxal‑5‑phosphate, the active form that helps enzymes move amino acids and glycogen around during effort. Capsules avoid the stomach upset and sugar swings some people get with sports drinks.

The label suggests one capsule before, during, and after training. Practically, take one with water 15–30 minutes pre-session, then one every 45–60 minutes for light sweat losses, and one after if you end with salt rings or a headache. Each capsule has only 40 mg sodium, which is small compared with typical sweat losses. If your sweat test or experience points to higher needs, you’ll likely layer additional sodium or use a higher-sodium product for long or hot sessions.

Skip or get clinician guidance if you have kidney disease, heart failure, uncontrolled high blood pressure, or you’re on medicines that change potassium or sodium handling: ACE inhibitors, ARBs, potassium-sparing diuretics like spironolactone or eplerenone, or loop and thiazide diuretics. If your Basic Metabolic Panel already shows low Sodium or Potassium, address that clinically first. For endurance events with heavy sweat rates, this low-sodium capsule is not a stand-alone plan for cramp prevention.
