More recently (2020-2021), we have improved our manufacturing processes and raw material sourcing, which has allowed us to change our inactive ("Other ingredients") amounts. For example, we have increased the amount of microcrystalline cellulose (which is white) in many of our products and removed MCT oil. This can lighten the overall capsule color.
Keep in mind that our products are formulated with natural ingredients. Due to the natural nature of our ingredients, some variation in color from lot to lot is expected.
