Assessment of nutritional status in subjects of MonaVie product users and non‐users ő a cross sectional study (1044.18)

Abstract

BACKGROUND: Phytonutrient intake is directly related to the risk of various diseases. Carotenoid levels in both serum and skin are well correlated with fruit and vegetable intake. Various non invasive techniques, including Reflectance Spectroscopy, are able to accurately detect skin carotenoid levels, and MonaVie's View scanner has been tested for a noninvasive method of assessing antioxidant levels. OBJECTIVE: Across‐sectional study by using MonaVie View Scanner to noninvasively measure skin carotenoid levels in subjects of MonaVie product users and non users. METHODS: Total 68 subjects were enrolled. 31 subjects were MonaVie product users and 37 subjects were non MonaVie product users. All subjects had the reflectance score measurements and blood draw. The plasma concentration of carotenoids were extracted and assayed by HPLC method. RESULTS: The carotenoid skin levels measured by View scanner are well correlated with the β‐carotene plasma concentration (r2 = 0.63). A logarithm values of plasma concentration have further confirmed the correlations between skin levels of carotenoids and plasma concentration of carotenoids (r2 = 0.64). CONCLUSION: Skin carotenoid levels are well correlated with plasma carotenoid concentration. Obviously, the users had higher skin carotenoid levels as well as plasma carotenoid concentration than non users. The noninvasive View scanner is feasible to evaluate the carotenoid plasma profiles.
