13 Sardines and Other Species of Oily Fish
Sardines are a good source of vitamin D. 100 gram serving contains 177 IU of the nutrient, which is 22% of your daily intake.
Other types of oily fish are also worth including in your diet if you spend a lot of time indoors. For example, a serving of halibut or mackerel will provide about 360-390 IU of vitamin D.
