For MSUD symptoms

Posted by PurplePegasus on Dec 24, 2015

I did research on MSUD. All the MD tech papers recommend this, as well as L-Carnitine. I take both when such symptoms manifest. But I also take charcoal for the "poisoning" life-draining symptoms and that works fast. Since I take these 3 to assist during a crisis, I am not sure which works best. I know the other two definitely help tremendously. I am not sure about this one which I added later. I try to avoid taking it because it's synthetic and I already take a natural B-complex. Still, when critical symptoms manifest, this is a million times better than anything prescription for someone with liver illness. Synthetic, but no side-effects here and no extra burden on the liver. For that, I give 5 stars.
