According to the experts at the Natural Medicines Comprehensive Database, Vitamin D doses recommended for routine supplementation in adults will continue to move higher.
Many experts, including me, have long been calling for higher doses.
Now new guidelines from Osteoporosis Canada recommend up to 1000 IU/day for adults under age of 50 and up to 2000 IU/day for adults over 50.
The Institute of Medicine in the US is also expected to raise recommendations sometime soon.
For now, the NMCD experts recommend 1000-2000 IU/day for most adults and 400 IU/day for most infants and children.
