Some people seem to need this form of folate, but for me they seem to cause problems after a week to ten days of taking them. Basically I just get a toxic flu like feeling. Too many methyl donor's seem problematic for some of us. If you need this form, they are very good, but if you don't have the mthfr polymorphism (can't convert folic acid), then these just provide too much methyl.
