Vikee is right about the B6. You also need to be careful with B3 (Niacin).Here is a paragraph on Niacin taken from CBSHealth by Metscape. The URL for the entire article, which is titled "Vitamins, Carotenoids, and Phytochemicals" is:
http://healthwatch.medscape.com/medscape/p...?RecId=151072&F A=1&SP=undefined[/URL] "Deficiencies and Toxicity of Vitamin B3 (Niacin). Niacin, also known as nicotinic acid, helps break down blood sugar for energy and also acts as a vasodilator, widening blood vessels and increasing blood flow. Dietary sources are mackerel, swordfish, chicken, veal, dried fortified cereals, pork, salmon, and beef liver. Current DRI recommendations are 20 mg. This vitamin may be prescribed for improving cholesterol levels, but supplements are unnecessary in people with normal health and diets. A deficiency of niacin causes pellagra; symptoms can include eczema, intestinal and stomach distress, depression, headache, thinning of the hair, and excess saliva production. Anemia may occur, although this is probably due to an accompanying deficiency in folic acid. [See Folic Acid, below.] Even mildly high doses of niacin can cause hot flushing of the face and shoulders, headache, itchiness, and stomach problems. Some report heart disturbances and temporarily lowered blood pressure. Large doses may produce ulcers, gout, diabetes, and liver damage, which are usually reversed when high doses are discontinued."[This message has been edited by JeanG (edited 07-29-2000).]
