Naturally occurring vitamin E from rice bran oil contains both tocopherols and tocotrienols. Tocotrienols are vitamin E related compounds found to have antioxidant properties. This antioxidant formula highlights gamma, the most potent tocotrienol. Studies indicate that the effect of combining tocotienols with tocopherols enhances vitamin E's antioxidant properties.

B-vitamins are essential components of numerous key enzyme systems, which are necessary for maintaining normal functionality of human body. Each B vitamin fills a different complementary need, that is why they should most often be taken together. B-vitamins also act as coenzymes to catalyze numerous biochemical reactions.

Methylcobalamin, an active coenzyme form of vitamin B-12, is essential for cell growth and replication. It is more concentrated than other forms of B-12 in the cerebrospinal fluid where it can be used by the central nervous system. It donates methyl groups to the myelin sheath that insulates certain nerve fibers. It may also play a role in maintaining a healthy sleep-wake cycle, as well as normal nerve function.

Source Naturals Pau d'Arco Extract contains 300% more active ingredient than whole pau d'arco. These active constituents are molecularly unbound and freed from the plant fiber. This product is derived form the highest quality bark of the purple lapacho tree found in Brazil and Northern Argentina.

Vitamins B are essential components of numerous key enzyme systems, without which the body cannot function. Each Vitamin B fills a different, complementary need, which is why they should most often be taken together. Vitamins B act as coenzymes to catalyze numerous biochemical reactions, and to aid in energy production, blood cell formation, and fat and protein/amino acid metabolism, and are important for the normal functioning of the nervous system.

Vitamin E is a fat-soluble vitamin and an antioxidantthat support cell membranes against lipid peroxidation. Vitamin E may also maintain healthy red blood cells, enhances circulation and supports healthy nerve and muscle function.

Vitamin B-6 is an essential nutrient required for the metabolism of lipids, carbohydrates, and proteins. It facilitates the conversion of amino acids from one to another and is necessary for the normal synthesis of hemoglobin, as well as the normal function and growth of red blood cells. Vitamin B-6 promotes a healthy Defense mechanism of body and Enhances recycle homocysteine back to the amino acid methionine, thus Beneficial Effectsing an unwanted build-up of homocystine. It is also needed for the synthesis of the neurotransmitters serotonin, gamma amino butyric acid (GABA) and dopamine and for the conversion of essential fatty acids into prostaglandins (chemical messengers).
