Clarification of interactions with vitamins

Finally, some of the names of comedications in the supplements class have been changed to make it clearer whether or not the interaction is due to a component of a multivitamin. The following vitamins can now be selected either as a single vitamin supplement or as part of a multivitamin:

Ascorbic acid (Vitamin C), Colecalciferol (Vitamin D3), Cyanocobalamin (Vitamin B12), Folic acid, Iodine, Nicotinamide (Niacinamide), Phytomenadione (Vitamin K), Pyridoxine (Vitamin B6), Retinol (Vitamin A), Riboflavin (Vitamin B2), Thiamine (Vitamin B1), Tocopherol (Vitamin E).

In particular, this makes a difference to oral integrase inhibitors, which are susceptible to chelation.
