Carnitine has been a staple in sports supplements for years. Aiding in fat loss, energy production, metabolism, and insulin modulation, Carnitine is a great supplement for not only those who are looking to improve body composition but anyone looking to optimize their performance. Synthesized in the liver and kidneys from the amino acids Lysine and Methionine, Carnitine is then stored in muscle tissue. The L form or L-Carnitine is the biologically active form that the human body can utilize. One specific form of L-Carnitine found in LIQUID L-CARNITINE LS3 is Acetyl-L-Carnitine which is more apt to cross the blood brain barrier and provide antioxidant properties as well as well as assisting the transport of fatty acids into the mitochondria for processing. The second form, L-Carnitine L-Tartrate has been studied in relationship to supporting activation at hormone receptor sites aiding in more efficient hormonal responses to resistance training. LIQUID L-CARNITINE LS3 from iSatori supplies the body high levels of L-Carnitine in three forms to help maximize all benefits associated with L-Carnitine supplementation. LIQUID L-CARNITINE LS3 is perfect to use on its own or can be stacked with other fat loss or muscle-building supplements to help you achieve your goals faster.
