I have been having a difficult time breathing after taking L-Methylfolate and my lungs seem to fill up as though I was a smoker. It seems to go away after I take Niacin. It's a double edged sword because I need the methylfolate for extreme depression right now but I'm having incredibly scary respiratory side effects. Would taking L-Methylfolate and methyl cobalamin together make a difference? Anybody know what could be happening? Please advise.
