What are good sources of vitamin D3?

Dr. Mehmet Oz, MD

The best sources of vitamin D3 tend to be salmon, tuna, mackerel (especially the flesh), and fish liver oils, although vitamin content varies in individual fish. Beef liver, cheese, and egg yolks also contain small amounts. If these foods don't sound very appealing to you, there is good news: your body produces vitamin D when ultraviolet rays from sunlight strike your skin. Spend about 10 to 15 minutes a day outside in the sun. Keep in mind that wearing sunscreen will prevent you from getting adequate vitamin D outdoors. In the summertime, an easy solution is skipping sunscreen on your legs for the first 15 minutes in the sun. Just make sure you apply in time to prevent any sunburn or damage.

To ensure you're getting all the D3 you need, I recommend you take 1000 IU in supplement form daily.
