Clean Label Project™ completed a study of 134 protein powder products from 52 brands. Products were screened for over 130 toxins including heavy metals, BPA, pesticides, and other contaminants with links to cancer and other health conditions.
Clean Label Project had the top-selling protein powder products – animal-based, whey, and plant-based – tested and reviewed by a third party analytical chemistry laboratory for industrial and environmental contaminants and nutritional superiority elements like antioxidant activity.
Every product tested is displayed in the product ratings with a rating of one, three or five stars so you can look up the products you purchase—and make informed future purchasing decisions based on science rather than marketing terms and manufacturer supplied data. Every brand is then rated so you can know the overall brand quality based on the products tested compared to other brands
