Need more vitamin D? Then, you need more sun... That's the best way to safely get what you need. The top 10 Vitamin D Rich Foods (from wiki) -- I'd steer clear of raw milk tho -- are:
1) Sunlight - Promotes vitamin D synthesis from cholesterol in the skin.
2) Cod liver oil - 1 tsp: 440 IU (over 100% DV)
3) Sardines - 3 ounces: 164 IU (41% DV)
4) Salmon - 3 ounces: 400 IU (100% DV)
5) Mackerel - 3 ounces: 400 IU (100% DV)
6) Tuna - 3 ounces: 228 IU (57% DV)
7) Raw Milk - 1 cup: 98 IU (24% DV)
8) Caviar - 1 oz: 33 IU (8% DV)
9) Eggs - 1 large: 41 IU (10% DV)
10) Mushrooms - 1 cup: 2 IU (1% DV)
