![]() Supplementation of milk fortified with approximately 240 IU vitamin D2 for three months did not achieve sufficient serum 25(OH)D levels in Indian children with vitamin D deficiency during winter. Serum carboxy-terminal telopeptide levels were similar in both groups but the serum procollagen type1 N-terminal propeptide levels were higher in the control than intervention group (P<0.007), following supplementation. A higher proportion of secondary hyperparathyroidism was observed post-intervention in control (39%) than in intervention group (13.3%) P<0.001. The serum 25(OH)D levels did not increase post-intervention with the dose used for fortification, but were significantly higher in intervention group as compared to control group. When blood levels were tested at the start of the study, 64 of participants were deficient. The mean (SD) baseline serum 25(OH) D level in control and fortification groups was 11.9 (3.8) and 11.4 (3.6) ng/mL (P=0.23), respectively. Holick and colleagues recruited about 100 adults and randomly divided them into six groups receiving various combinations of OJ fortified with 1,000 IU of vitamin D2 or D3, supplements of vitamin D2 or D3, and placebo drinks and pills. ![]() School-based study in Delhi between October and December, 2019.ĭaily supplementation of 200 mL milk fortified with 240 IU of ergocalciferol in intervention group (n=119) and 200 mL of plain milk in control group (n =116) for 3 months.Ĭhange in serum 25 hydroxy vitamin D (25(OH)D), parathyroid hormone (PTH), bone formation and resorption markers, and urinary calcium creatinine ratio (U-Ca/CrR). That may change, however, after the federal dietary guidelines are updated later this year.The study, published in the American Journal of Clinical Nutrition, was funded by the National Institutes of Health and by a division of Coca-Cola, which makes Minute Maid.To evaluate the efficacy of daily supplementation of 200 mL milk fortified with 240 IU of vitamin D2 (ergocalciferol).ĭouble-blind randomized controlled trial. After 11 weeks, all those getting extra vitamin D saw increases in blood levels of the vitamin, and there was no difference between those receiving it in pills or juice.Theres one catch: You cant buy orange juice-or any other food or beverage-with 1,000 IU of vitamin D, because government regulations limit fortification to 100 IU per serving. When blood levels were tested at the start of the study, 64% of participants were deficient in vitamin D. Holick and colleagues recruited about 100 adults and randomly divided them into six groups receiving various combinations of OJ fortified with 1,000 IU of vitamin D2 or D3, supplements of vitamin D2 or D3, and placebo drinks and pills. But can the body absorb vitamin D from orange juice as readily as from supplements? To find out, Dr. Holick, however, helped convince the makers of Minute Maid and Tropicana to give it a try. According to the Dietary Guidelines for Americans, soy beverages fortified with calcium, vitamin A and vitamin D are part of the dairy food group as they have similar nutritional composition to milk. In fact, the lack of fat in orange juice initially led beverage companies to be skeptical whether adding vitamin D to the popular breakfast drink would do any good. Holick, MD, PhD, of Boston University Medical Center, a leading vitamin D scientist and advocate of higher intakes, but they do drink OJ in the morning.Simply adding vitamin D to a food or beverage doesnt guarantee it will be bioavailable-usable by the body. about types of vitamin concentrates available, the problems involved in fortification, and the best methods for properly fortifying fluid milk products. Can your body really absorb the vitamin D in fortified orange juice, given that the vitamin dissolves in fat (as in fortified milk) but not water? A new study says it can, adding fortified OJ to the limited list of significant food and beverage sources of vitamin D.A lot of people dont drink milk, commented lead investigator Michael F.
