I have used supplements from a company called Puritan's Pride for many years. That is the only supplement company I know of with "Puritan" in its name. They have some supplements that I consider good and some that I don't. As with any supplements, you are going to get what you pay for. Their better supplements are definitely more costly, but they have "Buy 1 Get 1 Free" and similar "deals."
For the most part, their vitamin supplements are "natural," though they do carry some whole foods vitamins from a company called New Chapter. I have used their herb supplements, too, and have never had any complaints.
As with any supplements, it is important to read the labels and know exactly what you are buying and to do your research on supplements in general, especially vitamins and minerals.
