The 23andme test is now an "dna ancestry test". It is not the ancestry info you are seeking from this site; it is your raw data from the test that you download from the 23andme website, and then run it (the raw data) through one of the analysis programs mentioned (GeneticGenie, Livewello, Prometheus, etc.--which can contain cut and paste information from other databases like the U.S. government's dbSNP). Often these analysis programs will format your information into a nice chart/table that you can print out and pore over.
I don't know as I haven't gone as far as Amy Yasko analysis and help yet - but - I would have thought - if it is better than this other guy's demo - who is not a doctor - it must be pretty good I would have thought.
MTHFR is involved in converting inactive forms of folic acid into active folate. Being +/+ for MTHFR C677T reduces the activity of MTHFR to 30% of ideal. So supplementing with inactive folic acid is probably less effective than supplementing with an active form, for someone who has that MTHFR variation. But there's no indication that anything larger than a normal dose (400mcg or dutifully eating your vegetables) is at all helpful.
