Supports Immune Function* Nitrogen Transporter* Glutamine is considered to be a conditionally essential amino acid, which means that under certain circumstances, the body may require more glutamine than it can produce. In the body, glutamine functions as a major nitrogen transporter and is critical...

Muscle Growth* 9 Essential Amino Acids Protein Building Blocks* Amino acids are the subunits that make up proteins. They are necessary for the function of all cells, for tissue repair, and for the production of enzymes and neurotransmitters.* The body uses 20 amino acids...

Mixes Easily Builds Lean Tissue* Free Form Leucine is one of the three branched-chain amino acids (BCAAs) that is critical in muscle tissue structure.* Among the BCAAs, leucine is unique in its role as a signaling molecule that helps to regulate optimal skeletal muscle...

3,000 MG Highly Absorbable Fat Metabolism* Citrus Flavor NOW® L-Carnitine Liquid has all of the properties of carnitine in a highly absorbable liquid form. Carnitine is a non-essential amino acid that helps to maintain overall good health by facilitating the transfer of fatty acid...

Nitric Oxide Promoter* Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with other amino acids to rid the body of ammonia, a by-product of protein metabolism.* Citrulline also plays an important role in the healing...

Protein Metabolism* 1:1 Ratio Arginine and Citrulline are two amino acids that are integral to protein metabolism and utilization, as well as to the maintenance of muscle tissue.* Both are key intermediates in the urea cycle, where they participate in the detoxification of ammonia...

Muscular Endurance* Delays Muscle Fatigue* Beta-alanine is a non-essential amino acid that is used by muscle cells to synthesize carnosine.* Carnosine is a dipeptide (beta-alanine plus histidine) that functions as a buffer for the hydrogen ions (acid) produced during strenuous exercise, thus helping to...

Fitness Amino Acid* Protein Metabolism* Urea Detox* Ornithine is a non-essential amino acid that plays a central role in the urea cycle, functioning along with arginine and citrulline to rid the body of ammonia, a by-product of protein metabolism.* Because ornithine is converted into...

6 Amino Acids 5 G BCAAs 1.5 G Betaine BCAA Big 6 is an advanced caffeine-free sports supplement formulated to support exercise endurance and recovery from intense workouts.* BCAA Big 6 features branched-chained amino acids (BCAAs) to support muscle retention and recovery, and betaine...

Essential Amino Acids Leucine, Isoleucine, Valine Muscle Fuel* The Branched-Chain Amino Acids (BCAAs), leucine, isoleucine and valine are essential amino acids, and thus cannot be made in the body.* BCAAs are critical for muscle protein synthesis, and because BCAAs can be used as fuel...

2200 MG Per Serving Energy Production* Nitric Oxide Precursor* AAKG (Arginine Alpha-Ketoglutarate) is a metabolic derivative of arginine, which is a conditionally essential amino acid that has a number of vital roles in the body.* Arginine plays a pivotal role in the urea cycle,...

Pure Powder Muscular Endurance* Delays Muscle Fatigue* Beta-alanine is a non-essential amino acid that is used by muscle cells to synthesize carnosine.* Carnosine is a dipeptide (beta-alanine plus histidine) that functions as a buffer for the hydrogen ions (acid) produced during strenuous exercise, thus...

Protein Blend 20 Aminos With Vitamin B-6 Amino acids are essential nutrients in the maintenance, repair, and development of evolving muscle tissues.* Amino Complete™ is an advanced formula that combines a blend of protein and free-form amino acids, delivering 20 amino acids in one convenient...
