Vitamins

Vitamin B6 Pyridoxine

Necessary for protein and fat metabolism, hormone function (estrogen and testosterone), and the production of red blood cells, niacin, and neurotransmitters (serotonin, dopamine, and norepinephrine).

Used therapeutically for PMS, depression, morning sickness, carpal tunnel syndrome, and heart health (lowers homocysteine, an amino acid that, at high levels, can cause arteriosclerosis and build up arterial plaque).

Deficiency is uncommon, except in alcoholics and the elderly, and causes seizures, irritability, depression, confusion, mouth sores, and impaired immune function.

Drugs that deplete vitamin B6: antibiotics, oral contraceptives, isoniazid, penicillamine, and Parkinson's drugs.

Supplements are recommended for the elderly, alcoholics, and those with poor diets.
