This trio of essential amino acids (leucine, isoleucine and valine) shares a unique branched-chain structure and must be consumed in the diet. BCAA’s make up a great proportion of the total amino acid content in skeletal muscle, but are rapidly broken down (catabolized) for energy production during intense exercise. The best way to defend against BCAA loss (catabolism) is to keep levels elevated during and after training. Keeping your BCAA stores topped up has been shown to turn on anabolism, blunt catabolism, and shorten recovery time. Since leucine is the major anabolic BCAA, then make sure you use products with at least twice as much leucine as isoleucine and valine.
L-Carnitine L-Tartrate (LCLT): LCLT is a stable form of L-carnitine, which is readily absorbed by the body. Although its been known for decades that elevated carnitine levels aid in fat metabolism, more recent work from the University of Connecticut illustrates that LCLT is more than just a fat burner. In a randomized, double-blind, placebo controlled study researchers reported that 3 weeks of LCLT supplementation upregulated androgen (testosterone) receptor content in skeletal muscle and augmented luteinizing hormone secretion (a signaling hormone for testosterone production) in resistance-trained men. Such upregulation of the “androgen system” provides a safe means to naturally augment your body’s anabolic status—this is environment is especially important for enhanced recovery after training. In another study by the same research group, they showed that LCLT supplementation reduced exercise-induced muscle tissue damage after heavy squatting exercise—likely due to heightened anabolism and protein synthesis.
