Context: Citrus fruits contain unique flavanones. One of the most abundant of the flavanones, hesperidin, has been shown to prevent bone loss in ovariectomized rats. Objective: The objective of the study was to measure the effect of hesperidin with or without calcium supplementation on bone calcium retention in postmenopausal women. Design: The study was a double-blind, placebo-controlled, randomized-order crossover design of 500 g hesperidin with or without 500 mg calcium supplement in 12 healthy postmenopausal women. Bone calcium retention was determined from urinary excretion of the rare isotope, 41Ca, from bone. Results: Calcium plus hesperidin, but not hesperidin alone, improved bone calcium retention by 5.5% (P <.04). Conclusion: Calcium supplementation (Calcilock), in combination with hesperidin, is effective at preserving bone in postmenopausal women.
