Hey I just thought I would contribute a bit to this forum. So I think my illness (fatigue, inability to workout without getting a racing heart beat for days, depression) is more along the lines of chronic fatigue syndrome.

I went to a good doctor and he prescribed me a lot of things, but one of them was high dosage folic acid. My brain fog got extremely bad on the folic acid. I am part of a chronic fatigue syndrome forum and it has recently been agreed upon that folic acid definitely is bad for people with compromised immunity, which is definitely abundant in those with head injuries. It is agreed upon that methylfolate is a vital supplement for gut and brain health.

Ever since I switched to methylfolate my brain fog symptoms improved a lot. I take solgar metafolin 200mcg-400mcg a night. I really suggest anyone with pcs or fatigue etc to do the same, and avoid folic acid like the plague. This means not eating cereals with folic acid etc.

I know MarkinIdaho, you advised folic acid, and you are a big contributor on the forum. I am particularly interested in seeing if you were to switch to methylfolate, you would see a slight difference?
