You can buy 5-MTHF OTC in the U.S. if you don't feel like consuming a lot of meat.

Exactly. It's fairly affordable. Although for me there were other co-factors for me to feel the effects in my brain (almost surely Coq10) so I felt better when I took this and ate food (which normally did also have some meat in it).
