As many of you may know, the actual BRAND of a supplement matters quite a bit in determining its effectiveness. I was wondering what the current recommendations are (from various users, or FREDDD himself) for the most effective brands of Methylation supplements? Mainly I am looking to see if anyone has done some updated experimenting, and what they have deduced. For example, I use Jarrow and Source Naturals b12, but I havent experimented beyond this. Has anyone done so?
