No. In accordance with Elysium’s mission to provide the most innovative and high-quality products possible, Matter was developed with no artificial colorants and minimal inactive ingredients. The natural bilberry extract in Matter is what gives the tablet its unique coloring. The use of the ingredient as a natural colorant may result in some variation in the color of each tablet. We also took care to eliminate unnecessary binding agents and to include only the most necessary excipients. Slight variations in the surface of the tablets are purely cosmetic and do not affect the dose or efficacy of Matter. All Elysium products are held to incredibly high standards. Every lot of Matter is third-party tested for purity and quality to ensure safety and that each ingredient meets or exceeds the dose on the label.
