I have not been able to take ANY supps due to added fillers. In my quest to help my Mom, , with a severe B12 deficiency I came upon an excellent product line.
A little background here, my Mom has been getting b12 shots for a couple years and gets sick after it. Each time the illness had gotten worse and the last time she ended up in the hospital for days. Was it just from the b12 shot? Not sure but I strongly believe it was a BIG contributor. So I have been determined to help her and I was able to find a supplement that contains only Methylcobalamin B12 and purified water. Started her on it and couldn't wait to see her next test, now the shots had never really boosted her level at all but since I have had her on this her last B12 level tripled!!!! I was thilled to see that, and she does feel better, but this isn't her only health issue. I have ordered several supps from there and I am currently using Oil of Oregano and also vitamin D, the D is will water and the Oregano oil is with organic grapeseed oil.
It is worth the time to do a little research on the things you buy.
