Vitamin D
To help prevent bone loss and osteoporosis, you need vitamin D to maximize calcium absorption. Your body produces vitamin D naturally when exposed to UV rays from sunlight. But if you wear sunscreen or live in a cold climate, you're probably not absorbing the amount of UV rays necessary to trigger vitamin D production, so supplementing dietary vitamin D is crucial. Although the current RDI is 400 IU per day, research suggests vitamin D intake should be higher, especially for those who do not get adequate sun exposure.
