  • usefulness in medicine

    • beta-carotene is a major source of vitamin a, which supports healthy vision, immune function, and skin health.
    • its antioxidant properties help neutralize free radicals, reducing the risk of chronic diseases such as cancer and cardiovascular disorders.
    • it promotes skin health by reducing oxidative damage, enhancing hydration, and preventing premature aging.
    • beta-carotene is used to support lung health and reduce the severity of respiratory diseases.
    • it may help protect against uv-induced skin damage by acting as an internal sunscreen.

  • antibacterial and antimicrobial activity

    • while beta-carotene itself does not exhibit direct antimicrobial properties, its role in boosting immune function indirectly supports the body’s defense against infections.
