Why do some BioTrust products contain a form of caramel as an ingredient?Updated 2 years ago

Caramel is used for softgel coloring in select supplements. This yields an opaque, dark-colored softgel. This is important for protecting the delicate ingredients from light, oxidation, and rancidification. In other words, an opaque softgel is critical to ensuring maximum stability, freshness, and effectiveness.
