Vitamin D -
All others must be derived from the diet.
Right , and wrong at the same time. The body can naturally produce more than 1 vitamin.
Using cholesterol and UVB rays from the sun, the body can produce 10,000 IU of vitamin D from 30 mins of optimum sun exposure ( large areas of the skin exposed with NO sunscreen. )
The body can also produce Vitamin B3 (Niacin) using the amino acid Tryptophan. 1 mg of Niacin is produced for every 60 mg of Tryptophan consumed.
Recently there has been research into vitamins produced in the gut. Certain beneficial bacteria have been shown to produce B vitamins and vitamin K .

vitamin
Yes. It is true that Niacin is unique among the B vitamin in that the body can make it from the amino acid lysine.
That would be vitamin D. Vitamin D is a vitamin in of itself, but has shown to act like a hormone that allows proper metabolism of energy and helping preserve and promote muscle tissue. You do need to work out your muscle groups in order to get the full benefit of muscle vitamins.
Along with what? By itself, Vitamin E helps your body utilize Vitamin K, which in turn helps with blood clotting, thus helping prevent uncontrollable bleeding.
