Vitamin D in liver?

We are winding up the winter here in California and our vitamin D status may well be at the lowest point of the year. Until we can get out and get more sunshine, food and supplements are our best hope.
Is liver a good option?
Liver is packed with nutrition and it does have vitamin D in it, but not a whole lot.
I searched the USDA nutrient database for “beef liver” and found that raw beef liver has 1.2 micrograms of vitamin D per 100 grams of liver (about 3.5 ounces of liver). Most of us think in terms of “International Units” (or IUs) for vitamin D. 2.5 micrograms of vitamin D is the same as 100 IUs. Thus, liver has under 50 IUs of vitamin D. Many people take 1,000 or more IUs daily in the winter. Liver offers very little in comparison.
Liver, however, does pack a punch. Read more about the nutrients in liver and the Omega 3 fatty acids in liver.
