Beta-cryptoxanthin Supplement: Absorption and Function

Beta-cryptoxanthin (BCX) is a naturally occurring member of the carotenoid family, found in a wide range of fruits and vegetables. The unique biological functions of BCX have not been well-established, although BCX, like other members of the carotenoids have antioxidant functions. BCX, may also serve as a precursor of Vitamin A. Vitamin A has a wide range of functions including maintain immunity, vision, growth and development. Whilst not specific for BCX, epidemiological studies indicate that dietary intake of carotenoids may be of benefit in maintaining cognitive health and reducing stress via its antioxidant, anti-inflammatory and immunomodulatory properties. This pilot study aims to establish the relationship between supplemental dose and circulating concentrations of BCX and related carotenoids in circulation. Results obtained from this study will provide greater insight of bioavailability and carotenoid metabolism, necessary for larger supplementation in selected target populations.
