After age 25, active sports hurt more every year. Muscle "burn" and next-day soreness are why customers quit sports during their peak earning years. Taken an hour before sports, Sportlegs primes muscles to make less lactic acid with healthy lactate compounds of calcium, magnesium and vitamin D. Healthier than ibuprofen. Surprisingly effective. Available in lightweight plastic flip-top bottle with 120 capsules or moisture-resistant, tamper-proof 5 capsule pouch.
