Chris Kresser: Because as you know, this is a pet peeve of mine, and there are websites out there where you can connect your 23andMe results and they will spit back your methylation genetic profile along with a list of supplements that you should take solely on the basis of the genetic mutations that you have. And where you can start to see the limitations of this approach very quickly is that oftentimes with those computerized algorithms one mutation suggests that you would tolerate methyl donors like methylfolate really well, and so they’ll list those out next to that mutation, but then another mutation you have further on down suggests that actually you wouldn’t tolerate those methyl donors, so it tells you to avoid methyl donors. This is just one example and one reason why we cannot rely on the genetic profile alone to tell us what’s actually happening in the methylation pathways.
