The vitamin B complex consists of 12 related water-soluble substances. Eight are considered essential vitamins because they need to be included in the diet. Four are not essential because the body can synthesize them. Although these vitamins are chemically distinct, they are grouped together because they are found with one another in the same foods. Since they are water-soluble, most are not stored for any length of time, and must be replenished daily. The eight vitamins have both names and corresponding numbers. They are:
* B1 (thiamin)
* B2 (riboflavin)
* B3 (niacin)
* B5 (pantothenic acid)
* B6 (pyridoxine)
* B7 (biotin)
* B9 (folic acid)
* B12 (cobalamin)
Biotin is not always included among B complex supplements. The numbers that appear to have been skipped were found to be duplicate substances or non-vitamins. The four unnumbered components of the B complex that can be synthesized by the body are choline, inositol, PABA, and lipoic acid.
As a group, the B vitamins have a broad range of functions, including the maintenance of myelin, which is the covering of nerve cells. A breakdown of myelin can cause a large and devastating variety of neurologic symptoms.

The acne is back after years of remission and the dermo put me on solodyn which is extended release mino. I think this stuff is more powerful than the twice a day approach. Did that, did not work. The wierd thing is.......one week into the treatment, I was put on bylofen for muscle pain. I had never had this before and I think it is related to the mino.
