UNLABELLED: beta-Cryptoxanthin displays a unique anabolic effect on bone calcification. In women with osteoporosis, serum beta-cryptoxanthin and 25-OH-vitamin D(3) showed a weak but significant correlation and exhibited a complementary seasonal distribution. The potential role of beta-cryptoxanthin as a nutritional approach to improving bone health deserves further evaluation. INTRODUCTION: Dietary intake and serum levels of beta-cryptoxanthin have been inversely related to different bone and joint disorders and in vitro and animal studies have shown that beta-cryptoxanthin displays a unique anabolic effect on bone calcification. Due to the emerging role of beta-cryptoxanthin in bone biology, we aimed to assess the serum distribution and variability of beta-cryptoxanthin and their potential relation to 25-OH-vitamin D(3) in women with osteoporosis. METHODS: Serum concentrations of alpha- and beta-cryptoxanthin and 25-OH- D(3) in women with osteoporosis (N = 644) were analyzed using a quality-controlled high-performance liquid chromatography (HPLC) method. RESULTS: Overall, significant seasonal variations were found for the three analytes and inter-individual variation was also high (60-73%). beta-cryptoxanthin and 25-OH-vitamin D(3) exhibited a marked complementary seasonal distribution in serum, with vitamin D displaying the highest values in summer and beta-cryptoxanthin in winter. CONCLUSIONS: Given the anabolic effect of beta-cryptoxanthin on bone calcification and its complementary seasonal distribution with respect to 25-OH-vitamin D(3), the potential role of beta-cryptoxanthin as a sustainable nutritional approach to improving bone health deserves to be further evaluated.
