Chromium is a natural trace mineral in human nutrition and is needed for proper metabolism of sugar in humans. It is vital for metabolism of fats and carbohydrates. It helps move blood sugar from the bloodstream into cells to be utilized as energy and turn fats, carbohydrates, and proteins into energy. Chromium helps stimulate fatty acid and cholesterol synthesis, which are needed for brain function and other body processes. It activates numerous enzymes that are required to drive many chemical reactions essential to life. Chromium supplements also improve glucose tolerance in people with Turner's syndrome, a disease associated with glucose intolerance. It is also vital for insulin metabolism. It regulates hunger and decreases cravings.

Conjugated Linoleic Acid or CLA is a non-essential fatty acid that may be found in cow and sheep meat, and dairy products. It is known to decrease body fat in obese and overweight people. It works by inhibiting the action of the lipoprotein lipase (LPL) enzyme that is responsible for the transfer of fat from the blood stream to the fats cells. It has powerful anti-carcinogenic properties that fight free radical cells from damaging the cells. It also helps control blood sugar levels. It encourages muscle growth and improves the metabolism which accelerates weight loss. It reduces the risk of heart diseases. It is also an antioxidant.

DL-Phenylalanine is a a-amino acid. The biological functions of D-amino acids remain unclear although some, such as DL-phenylalanine shows some pharmacological activity. It is sold as a nutritional supplement because of its analgesic and antidepressant activities. This analgesic activity can be explained by the possible blockage by D-phenylalanine of enkephalin and degradation by the enzyme carboxypeptidase A , and the mechanism of antidepressant activity may be accounted for by the precursor role of L-phenylalanine in the synthesis of the neurotransmitters, norepinephrine and dopamine. High levels of norepinephrine and dopamine are believed to have an anti-depressant effect.

DL-Phenylalanine works with body’s natural ability to ease pain. It assists in increasing the lifespan of brain chemicals that relieves pain. It is particularly effective in reducing pain caused by arthritis and aching muscles. DL-phenylalanine can treat persistent pain by stimulating nerve pathways in the brain responsible for controlling pain. Its effect increases if used with prescribed pain killers. DL-Phenylalanine, which is a combination of essential amino acid L-phenylalanine and D-phenylalanine, blocks an enzyme in the nervous system that enhances pain signals. This disturbance of pain signals causes the body’s healing mechanisms to start working faster. Use of DL-phenylalanine is also reported to have helped people in improving their mood and in treating depression. This is because a higher proportion of production of brain chemicals dopamine and norepinephrine, if went out of balance, cause depression, stress and frustration. Increasing the levels of these chemicals has an anti-depressant impact in the body.

DMAE is an organic compound also known as dimethylaminoethanol, Deanol, beta – dimethylaminoethyl alcohol or N, N-dimethyl-2-aminoethanol; a biochemical precursor to the peripheral and central nervous systems’ neurotransmitter acetylcholine, which is also one of the many neurotransmitters in the autonomic nervous system and furthermore the one and only active neurotransmitter in the somatic nervous system, as well as in all autonomic ganglia. DMAE is related to choline and is deemed to have nootropic properties. It seems that supplements containing DMAE, which have gained popularity in recent times, improve the energy levels, promote relaxation during sleep and improve memory and learning capabilities. In athletic and body building circles, athletes use DMAE to shorten the recovery time after demanding trainings and to improve the overall athletic performances.

Vanadyl Sulfate is an inorganic compound of vanadium and the most widely found laboratory source. It is derived from petroleum residues, which is known as the most common commercial supplier of vanadium. Humans do not require vanadium, which means it is not necessary for humans to ingest vanadium in order to survive. Some vanadyl compounds are known to have the effect of mimicking the effects of insulin, which led to a popular use of Vanadyl Sulfate as a dietary supplement. In body building circles it is believed that Vanadyl Sulfate is increasing the performance and that muscle cells take up glucose easier under the influence of Vanadyl Sulfate. The insulin mimicking characteristic is believed to allow amino acids, proteins and carbs to directly enter muscles, but the scientific proof is still under deliberation.
