Sportlegs is premium natural-source European lactate compounds of
calcium and magnesium plus
Vitamin D all in a vegetable capsule.
Ordinary "cal/mag" supplements are typically carbonate, citrate,
phosphate or gluconate compounds but SportLegs uses lactate (not
lactose) compounds of these minerals. SportLegs uses lactate, your
body's primary high-exertion muscle fuel, to signal muscles not to
overproduce lactate before you even begin exercise; therefore, you can
push harder before you start to feel the burn.
