Lillie&Lee, a pet wellness brand with over 900,000 social media followers, has committed to extending independent third-party testing and public Certificates of Analysis across its entire product line. This includes the company's functional supplement chews for hip-and-joint support, multivitamins, and allergy care, as well as its human supplements. The premise of this strategic venture is rather simple — the business believes that "pet owners shouldn't have to take a brand's word for quality."
Overall, Lillie&Lee's transparency move builds on its existing practice of testing and publishing results for its CBD products. The pet wellness brand already provides full ingredient lists that also emphasize no artificial preservatives, fillers, or additives. Lillie&Lee also emphasizes its use of U.S.-grown hemp for its CBD line and notes that all products in its range are manufactured domestically.
