LMNT

LMNT began as a home recipe. Robb Wolf, a biochemist and writer, kept seeing the same pattern in athletes and low-carb eaters: they drank plenty of water and still felt flat, crampy and foggy. The missing piece was salt. He mixed his own electrolytes to fix it, shared the formula, and watched it grow into one of the fastest-selling hydration brands around.

The formula is deliberately plain. Each serving carries a full gram of sodium alongside potassium and magnesium, the amounts active people actually lose and need to replace. There is no sugar, no colour and no filler, and the brand explains the reasoning behind every figure on the label.

For anyone who trains hard, fasts, or simply runs low on salt, water on its own falls short. LMNT is the properly dosed answer, and its refusal to sweeten the mix is the kind of honesty we look for.
