Transparent Labs is considered one of the most legitimate supplement companies around, with layers of integrity. They use independent testing on all of their products, their advisory board is packed with experts, and the end result is a series of products that live up to the claims. However, the Better Business Bureau (BBB) currently has a rating of “B-” for Transparent Labs. Their reason for the low rating is two-fold: The company hasn’t been in business very long and Transparent Labs has failed to respond to complaints made about the company. Despite this, many customers have reported positive experiences with the quality of the products and services. Therefore, caution is advised when dealing with Transparent Labs and its associated websites. It's best to check the ingredients label carefully and consult with a doctor before using supplements.
