Not only can,should!: The recommended daily amount of vit d is insufficient for most people. Most adults need to take 5-8, 000 iu/day during the winter months to achieve optimal levels. It is considered safe to take 10, 000 iu/day and generally one must take 40, 000 iu/day to become toxic. In summer you can get enough d from being in the mid-day sun without protection, but taking d is not harmful. See comment:.
