The Supplement Database launched in early 2019 as a place to find easy to read, unbiased, and research-based supplement ratings and reviews. Since then, it's grown to include ratings on both ingredients and products in multiple categories. At its core, the database uses information from peer-reviewed research articles to rate supplements in an easy to understand format.
All products are rated in seven areas; a product is given a thumbs up/down in each area. Based on these thumbs up and down ratings, products are also given an overall up or down recommendation.
