lutein

• lutein, also known as xanthophyll, is a naturally occurring, oxygenated carotenoids essential for human eye health. it is concentrated primarily in the macula and retina of the human eye, acting as a potent antioxidant that filters harmful blue light, protecting ocular tissues from oxidative stress and reducing the risk of age-related macular degeneration (AMD), cataracts, and retinal damage.

• usefulness in medicine

  • lutein is widely used as a dietary supplement to support and enhance visual health, significantly reducing the incidence and progression of AMD and cataracts.
  • its strong antioxidant properties protect skin cells from UV-induced oxidative stress, reducing signs of skin aging and improving skin hydration
  • lutein supplementation supports cognitive health, potentially reducing the risk of cognitive decline and neurodegenerative conditions such as dementia and alzheimer’s disease.
  • lutein also plays a role in strengthening immune response, enhancing overall health and resistance to oxidative damage.
  • antibacterial and antimicrobial activity
  • lutein exhibits antimicrobial effects primarily through potent antioxidant activity and immune system modulation, thereby enhancing the body’s defenses against microbial infections.
• bacteria:
  • staphylococcus aureus
  • escherichia coli
