Vitamin B Complex probably has more applications than any other nutritional supplement. That's because B complex is a lot more than "vitamin B." A good B complex vitamin supplement will provide all of the following in a single convenient pill:

Biotin (B7)

Folic Acid (B9)

Inositol

PABA (para-aminobenzoic acid)

Vitamin B1 (thiamine)

Vitamin B2 (riboflavin)

Vitamin B3 (niacin)

Vitamin B5 (pantothenic acid)

Vitamin B6 (pyridoxine) and

Vitamin B12 (cobolamin).

Vitamin B complex tablets and even broader-spectrum products containing the complete B complex can simplify the process of supplementation for supporting alcoholism, depression, diabetes, hair problems, skin problems, lupus, multiple sclerosis, and stress.

Vitamin makers generally package vitamin B complex in two forms: B-50's and B-100's. In a B-50 complex you typically get at least 400 micrograms of folic acid, 50 micrograms each of biotin and B12, and at least 50 milligrams of all the other B vitamins. You usually get twice these amounts in a B-100 vitamin B complex supplement, except the dosage of folic acid (400 micrograms) remains the same. B-100 vitamin B complex tables usually contain 100 micrograms of biotin and B12, and 100 milligrams of all the other B vitamins.

There is one notable side effect of most vitamin B complex products. Yellow urine. Sometimes, neon yellow urine. The tint in the urine is caused by excess riboflavin (vitamin B2).

Vitamin B complex can occasionally give urine a pungent, distinctively "vitamin-like" odor. The first few times you take vitamin B you can experience a little indigestion, if you don't take vitamin B complex with food.

If you're taking vitamin B complex to support specific conditions, here are the minimums you need:
