In brief: Usually Methyl but..

One thing is clear- Cyano is worst- it has small amounts of cyanide the body must detox & convert it to an active form; little is converted.
Methyl is the active form, esp. good for those with MTHFR mutations & neurological symptoms & best for most. Some do better with Hydroxo. Experts agree Hydroxo better than Cyano but haven't seen many comparisons of Met vs. Hydr.See http://tinyurl.
