At first I was all for this, as it seems quite innocuous and a far superior form of folate. I posted in the supplements forum a while back about how the highest dose, 4.5mg, of low-dose naltrexone was giving me horrible stomach problems and an inability to wake up in the morning. It turns out that it was the combination of that and methylfolate that was causing it. Also, back when I was on Buspar, the combination of that and methylfolate made my blood flow extremely poorly. When I'd sit down to mediate, my legs would fall completely asleep within minutes.
Who knows what else it could interact with? I think this is something that shouldn't be put in, and being that I am on LDN, I will not even be able to buy this vitamin if it has it.
