What is Astaxanthin?

Astaxanthin is a coloured substance or pigment that comes from the carotenoid family group. Microalgae mainly produce it and are known for their antioxidant properties. It helps to protect the cells inside the body, including the organs, brain, and skin. It protects from harmful chemicals and reduces inflammation, which are essential factors in ageing and long-term health issues. Further, it supports eye function.
