The article examines the effects of astaxanthin-encapsulated polymeric micelles on mesenchymal stem cells (MSCs), showing significant improvements in their proliferation and differentiation into adipogenic, chondrogenic, and osteogenic lineages. In the C60a formula, astaxanthin enhances cellular regeneration, supports tissue repair, and boosts overall cellular resilience. This study directly supports the product’s goal by demonstrating astaxanthin’s ability to promote stem cell function and longevity.
