astaxantine

Astaxanthin is a red-pink pigment found in seafood such as shrimp and certain fish, as well as in the feathers of flamingos. It is structurally similar to beta-carotene but may be safer than vitamin A, which is lipid-soluble and can accumulate in the body.

Key insights about astaxanthin from Andrew Huberman on the Huberman Lab include:

• Vision Benefits: Astaxanthin may help offset age-related vision disruptions by increasing ocular blood flow, which is beneficial for eye health.
• Fertility: Some studies suggest that astaxanthin can significantly improve fertility rates in men, especially in those who were previously infertile, possibly due to effects on blood flow.

This compound also appears to enhance antioxidant enzyme profiles and has a variety of other health effects, making it an interesting supplement for overall wellness 1.
