Acetyl-L-Carnitine (ALCAR) is a little bit like your 401K: you need it, you know you should pay attention to it, but itÕs not exactly the sexiest topic. We know; we feel you! But we also know that ALCAR is one of the most fascinating, useful, and physiologically exciting workout supplements on the planet. YouÕre hard-pressed to find a single other ingredient that is involved in so many critical bodily processes: fatty acid and carbohydrate metabolism, neurotransmission, exercise performance and capacity, brain function Ð the list goes on! So, like your 401K contribution, donÕt forget to pay into your ALCAR fund.
