I Trust Dr. Mercola
I take an Awful Lot of Supplements, and at 75 I am in Good Health. I shared this one with my Better Half and with all the others I take its difficult to tell what is working and How. But Ive been in Good Health over the years and Im Pretty Sure that s Big part of that is due to Eating right, getting the Necessary Exercise and making Sure that the Supplements We take are NOT just off the local Drugstore shelf. The Bulk of what is sold from this site is Very Competitive among the vendors involved and to a Large degree, they Are interested in your Good Health. The End Result is to do the Research if you are Still not sure, or just Curious.
