L-Carnitine L-Tartrate (LCLT) is the biologically active form of Carnitine, an ammonium compound biosynthesized from methionine and lysine. Of the many ingredients included in most supplements these days, LCLT is one of the rare ingredients with a solid foundation of research behind it for use in humans, especially with regards to resistance training.
LCLT has been postulated to assist in supporting healthy body composition in a variety of manners.* LCLT has been speculated to increase the amount of fat burned during resistance training, and enhance the consumption of fat as a source of fuel.* In addition, supplementation of LCLT can assist individuals in managing their weight via mobilization of fatty deposits in adipose tissue (Pekala, et al., 2011).*
LCLT supplementation has also been observed to favourably alter concentrations of hypoxanthine and xanthine oxidase following exercise, both known to be markers of metabolic stress. *This occurs due to 1) the oxidization of AMP to hypoxanthine following the activation of adenylate kinase on a pool of ADP and hydrogen protons, and 2) the proteolytic cleavage of xanthine dehydrogenase, resulting in xanthine oxidase. By supporting a healthy concentration of these metabolic stress markers, LCLT may reduce the generation of superoxide radicals formed during exercise and the immediate initiation of lipid peroxidation (Spiering et al, 2007).*
LCLT supplementation has also been suggested to promote a reduction in the muscle damage markers myoglobin and creatine kinase following exercise (Volek et al, 2002) and to attenuate the ammonia accumulation (Broad et al, 2008).* Although previous studies found these benefits in subjects using 2 grams of LCLT a day, these previous findings have been supported by Ho et al. (2010), who found that supplementation of LCLT can reduce damage to muscle tissues following exercise, and subsequently optimize muscle tissue repair in subjects using only 1 gram of LCLT daily. At this dose, a bottle of Ergogenix’s L-carnitine provides you with a cost effective supply of 1 month of LCLT.
LCLT should be taken with meals, as studies suggest that the effects of carnitine on cardiac muscle contractility in the presence of fats and carbs can lead to a lowering of one’s heart rate at multiple levels of VO2 peak utilization (Broad et al., 2011). Feeding following resistance exercise has been suggested to increase androgen receptor content, which can result in increased testosterone uptake due to luteinizing hormone secretion via feedback mechanisms. The same research suggests that the supplementation of LCLT in individuals resulted in up regulation of androgen receptor (AR) content during a state of rest, possibly supporting increased protein synthesis.*The combination of feeding following resistance exercise and LCLT supplementation suggests that less muscle damage occurs due to this increased AR content, promoting recovery (Kraemer et al, 2006).
