For folate deficiency, I notice you recommend vegan supplements since folate is higher in organ meats. Why not recommend supplements from the animal source? Have you had experience with animal sources of folate in supplement form?

Chris Kresser: I’m not sure what supplement you’re referring to. Folate is a chemical structure. As long as it is folate and not folic acid, where it’s derived from should not make that big of an impact. The major question there is what type of folate you supplement with.
