Our Verdict
Worst-tested in our review. Whitness Nutrition's testing identified Garden of Life Unflavored Collagen Peptides as having the highest arsenic levels of 30 collagen products tested. Despite the brand's clean-eating positioning and Nestle ownership, the actual contamination data is concerning. Skip in favor of literally any winner on this list.
