Amino Acids

Amino acids are the building blocks of protein. Protein has an important job in building and rebuilding body tissue and providing the body with nitrogen, an essential element for all living beings. There are both essential and nonessential amino acids. Essential amino acids must be obtained from the diet; nonessential amino acids are made by the body. READ MORE > science beakers

Amino Acids
Acetyl L-Carnitine 500 mg (Item #740)

Acetyl L-Carnitine (ALC) is a molecule composed of acetic acid and L-carnitine bound together. It is produced naturally in humans, with the greatest amounts being found in muscles, the brain, and in the testicles. As part of its role in supporting mental function, ALC may help support memory, attention span and mental performance. It is also important in the production and release of one of the brain’s vital neurotransmitters, known as acetylcholine. ALC may also support healthy function of the male reproductive system and improve energy transfer within cells.

Amino Acids
L-Arginine 500 mg (Item #738)

L-Arginine is one of the amino acids produced in the human body by the digestion, or hydrolysis, of proteins. Because it is produced in the body, it is referred to as "nonessential," meaning that humans do not need to ingest it through food or supplements. Because L-Arginine is naturally converted into nitric oxide, a blood vessel dialator, by the human body, researchers have conducted preliminary studies to determine the effectiveness in using it as a supplement for supporting cardiovascular health. Other studies indicate that L-Arginine promotes immune health and supports the liver. Athletes supplement with L-Arginine for its benefits in building lean muscle mass and supporting blood flow while performing strenuous exercise.

Amino Acids
L-Carnitine 500 mg (Item #739)

L-Carnitine is an amino acid that acts as a vitamin-like compound, responsible for the transport of long-chain fatty acids into the energy producing mitochondria inside cells. Since the carrier molecule for fatty acids, acyl-CoA, cannot penetrate the cell membrane of the mitochondria without carnitine, a deficiency in carnitine results in decreased fatty acid concentrations in the mitochondria, and as a result, reduced energy production. L-Carnitine is only found in animal food sources such as meat, poultry, and dairy products. L-Carnitine can be made in the human body, although premature infants and some adults do not make sufficient amounts. L-Carnitine is a popular supplement for heart health, liver health, and weight management...Full Details

Amino Acids
L-Glutamine 500 mg (Item #737)

L-Glutamine is the most abundant amino acid found in muscle and is important for tissue rebuilding and repair. It is converted to glutamic acid in the body where it supports cerebral function. It also assists in maintaining a healthy gut as it is the primary fuel for the cells lining the digestive tract.
