EHPlabs Acetyl L-Carnitine is HPLC tested and proven to be the highest quality pharmaceutical grade Acetyl L-Carnitine on the market. The fine crystalline powder and the potency of a concentrated serving size is testament to this. Acetyl L-Carnitine is a naturally occurring amino acid that promotes the transportation of free fatty acids into the mitochondria (core of the cells), where they are burned off as energy. Acetyl L-Carnitine also assists muscle recovery after strenuous exercise and promotes optimal heart and brain function. EHPlabs wanted to ensure that the Acetyl L-Carnitine pharmaceutical quality was maintained, hence, this product has not been artificially flavored or colored. Acetyl L-Carnitine has a naturally occurring sour lemon taste and EHPLabs recommends that it should be taken as a “stack” product, and mixed into a serving of OxyShred, Buzz or Beyond BCAA.
