The burning sensation that forces you to back off during hard efforts comes from lactic acid accumulation, and your body's threshold for that accumulation determines how long you can sustain intensity. SportLegs approaches this limitation by pre-loading your bloodstream with lactate before exercise begins. The theory: elevated blood lactate signals muscles to reduce their own lactate production, raising the threshold where burn sets in. Rather than masking the sensation with stimulants or pain relievers, the formula works with your body's existing feedback mechanisms.

The ingredient list is straightforward. Calcium lactate and magnesium lactate provide the lactate compounds that comprise 87% of the formula, sourced from European suppliers. Vitamin D3 (cholecalciferol) supports calcium absorption and rounds out the active ingredients. The vegetarian capsules contain no stimulants, sodium, dairy, gluten, GMOs, or calories. SportLegs has maintained FDA Generally Recognized As Safe status since 1984, and the formula is legal for competition under WADA, USADA, UCI, and NCAA rules.

Dosing follows body weight: one capsule per 50 pounds, rounding up. A 150-pound rider takes three capsules; a 180-pound rider takes four. Take the dose 30 minutes before activity, which is how long the formula needs to reach effective blood levels. For sustained efforts or tournament competition, re-dose with your full weight-appropriate amount every two hours to maintain the effect. Unlike supplements that require daily loading phases over weeks, SportLegs works on a single-dose basis whenever you need it.... Read More
