L-lysine is an essential amino acid, important for the absorption of calcium, the formation of collagen (contained in cartilage, connective tissue, skin, hair and bone), and the production of bone tissue. Free form amino acid, high purity, well tolerated. Learn More

L-arginine is considered a semi-essential amino acid and is thought of as one of the bodybuilding amino acids because the body uses it to release growth hormone. Human growth hormone is used by the body to build muscle strength and tone and to enhance the burning of fats. L-arginine is important in the urea cycle for the metabolism of ammonia produced in the breakdown of protein. L-arginine also stimulates the production of nitric oxide which supports vasodilation. Free form amino acid, high purity, well tolerated. Learn More

As early as 1940, biotin was being researched for its effectiveness in promoting healthy hair and nails. It is an essential coenzyme for a variety of carboxylation reactions, and is involved in the metabolism of fats, sugars and amino acids. Learn More

This formula is a combination of pyridoxine hydrochloride and pyridoxal-5-phosphate (P-5-P, the coenzyme or "activated" form of B6). As P5P, vitamin B6 is extensively involved in the metabolism of amino acids, lipids and nucleic acids. Supplementation with vitamin B6 as P5P can be helpful for those unable to produce it efficiently from pyridoxine in the liver. Excessive protein intake, alcohol or contraceptive use also indicates a greater need for vitamin B6. Vitamin B6 plays a crucial role in the multiplication of cells. Learn More

Phosphatidylcholine, a primary component of lecithin, is converted in the brain into the neurotransmitter acetylcholine. Researchers have found acetylcholine to be a primary carrier of memory. Learn More

L-tyrosine is a non-essential amino acid and a precursor to adrenaline, norepinepherine, dopamine and L-dopa. These neurotransmitters are involved with mental function, mood, satiety and response to stress. L-tyrosine is also involved in the production of thyroid hormone and the skin pigment melanin. Free form amino acid, high purity, well tolerated. Learn More

Supports the function of the thymus gland, the master gland of the immune system. This natural glandular material is processed by lyophilization of glands derived from government-inspected, range-fed animals, raised in New Zealand without hormones or antibiotics. The material is frozen, then subjected to a high vacuum that vaporizes moisture directly from the solid state, thereby maintaining its biological activity. Learn More

This formulation incorporates the highest potency quercetin available, derived from a non-citrus, hypoallergenic plant source, and stabilized with additional antioxidants so as not to auto-oxidize (degrade spontaneously). Quercetin has been shown to support the integrity of mast cells, which play a key role in controlling the release of histamine.* In addition, Quercetin has been shown to reduce the production of prostaglandins and leukotrienes Learn More

For that Buddha-like feeling! 200 mg of Zen offers a unique and natural way to promote relaxation without sedation.* This formula contains a combination of L-theanine and GABA. L-theanine, found in green tea (Camellia sinensis), has been shown to stimulate the production of alpha-wave activity in the brain. Alpha-waves are involved in reducing anxiety while increasing mental alertness and acuity. GABA is a major inhibitory neurotransmitter that is critical for normal brain function. Learn More
