Lutein is one of two major carotenoids found in the human eye, acting as a light filter to protect tissues from sun damage [1.2.1]. To maximize its benefits for eye health, it's crucial to understand what you should not take with lutein.

While generally considered safe, astaxanthin supplements can cause side effects for some individuals. Studies have used various amounts daily for periods up to 12 weeks, with some reported issues including increased bowel movements and red stool color.
