                                According to the U.S. Pharmacopeia (USP), only about 1% of supplements in the U.S. are verified by their program, and Nature Made accounts for a significant portion of this group. This third-party testing is a critical factor when assessing if you can trust Nature Made vitamins for quality, purity, and potency, but it's not the only piece of the puzzle.
