Who Should Buy This
If you're on a ketogenic diet and experiencing the 'keto flu' — muscle cramps, headaches, fatigue, or heart palpitations — these electrolyte products are specifically calibrated for your mineral needs. Skip if you're not on a low-carb diet, as the high sodium content may exceed standard dietary requirements.
How We Tested
We spent 6 weeks testing 10+ electrolyte products specifically formulated for ketogenic diets, evaluating each for keto ratio compliance, carb content, and mineral balance tailored to keto needs. Our team of keto nutritionists and metabolic health specialists assessed sodium-to-potassium ratios, magnesium bioavailability, and strict zero-carb verification.
