Hi Paul,
I started with the basics, the vitamins, minerals, omega3, lecithin, and a few misc items. Then when I added mb12 I leared about potassium quickly. Each time I ran out of steam I foeund something else that revved up healing again; adb12, SAM-e, l-carnitine fumarate, increased zinc fro 15mg to 65 mg/day, Metafolin. Some things made no difference. Others have reported magnesium, vit D, Vit C, Vit A, d-ribose, B2, p5p,TMG and so on. For some, it was the active froms that helped, Metafolin instead of folic/folinic acid, p5p instead of b6, mb12 and adb12 instead of cyanocbl or hydroxycbl. Almost anything essential, and even some ot the things considered "not essential" could be what holds things up. So I do lots and lots of mini-trials to see what made a difference. In many cases it takes tge correct combination and sequence. So if a person tries SAM-e before mb12 and Metafolin, it has a huge effect but if tried after mb12 and metafolin which generate SAM-e, it may not have any effect or very little. So SAM-e acts as a surrogate for mb12 in methylation but NOT as mb12 for other effects. Carnitine may make no difference at all if the person is deficient of adb12 and conversely, adb12 may have no effect if very deficient of carnitine. A person can be very deficient of adb12 while taking mb12, cyanocbl and hydroxycbl and a person may be very deficient of mb12 despite taking adb12, hydroxycbl or cyanocbl. Even the brand of some things makes a big differnce, such as mb12, adb12 and carnitine.
