Children May be Able to Tolerate up to 2,000 IUs of Vitamin D

October 2008

Raising current vitamin D levels from 200 IU to 2,000 IU could provide even greater support for healthy bones amongst children and have long-term health benefits, according to new research. Only children given the equivalent of 2,000 IUs a day of vitamin D-3 showed blood levels of the vitamin at a level considered optimal for adults. “Our research reveals that vitamin D, at doses equivalent to 2,000 IUs a day, is not only safe for adolescents, but it is actually necessary for achieving desirable vitamin D levels,” said lead researcher Chada El-Haff Fuleihan from the American University of Beirut-Medical Center, Lebanon. Calls to increase the current recommendations of 200 IU of vitamin D per day for children and adults up to 50 years of age to 800-1,000 IU vitamin D-3 have become more frequent in recent years.
