5-10,000 iu/day: There are many proven benefits of Vitamin D3. While the RDA is only 600-800 iu/day, many experts recommend 5-10,000 iu/day to achieve optimal serum levels of 50-100. The only hazard is from taking too much, but one has to take at least 40.000 iu/day for months to get toxic. It's wise to take some Vit K2 with it.
