Not sure if this list is complete. Seems that taking only certain supplements involved would lead to a deficiency in others.
"Is there any evidence to support this? Well, I am looking at the ARI data gathered from over 18,500 parent surveys. Let's say Pfeiffer is exactly correct and under-methylators are about 45% of the "autism" population. These are the values for the precursors for methylation:
- calcium 39% saw improvement
- DMG 43% saw improvement
- Folic acid 44% saw improvement
- B6/mag (both of these are precursors) 46% saw improvement
- Zinc 43% saw improvement"
