The Secrets of Vitamin D – How Much Vitamin D you need

If you are in good health, the amount of vitamin D that you require each day will depend on your age. As you get older, you will need to increase the amount of vitamin D that you consume because your body will not be able to create and utilize as much vitamin D as a younger person.

In this section, we will provide you with the general guidelines for daily amounts of vitamin D (RDA) for the different age ranges. You need to bear in mind that your doctor may require you to consume higher levels of vitamin D if you currently have a deficiency or are at risk of bone disorders like osteoporosis. Be sure to meet with your doctor to discuss your needs.
