Benefits of Vitamin D
Vitamin D is increasingly being viewed as important. It’s well known for working with calcium to strengthen your bones, but it may also help prevent osteoarthritis, reduce your risk of certain cancers, fight inflammation, and help regulate blood pressure.
Recommended Amount: How Much You Need
There’s mounting evidence to support a bump in the daily dose of vitamin D. While the government recommendations are 400 international units (IU) per day if you’re under 70 years of age and 600 IU if you’re over 70, several members of the RealAge Scientific Advisory Board now recommend taking 1,000 IU of vitamin D if you’re under 60 years of age and 1,200 IU if you’re over 60. The daily upper intake level for D is 2,000 IU a day — so anything up to that is generally considered safe.
Good Sources of Vitamin D
There are three ways to get vitamin D: food, sunlight, and supplements. If you’re not getting enough from your diet, or you don’t spend much time outdoors (just 10–20 minutes in the sun can significantly boost your body’s production of vitamin D), take a daily vitamin D supplement.
