what are the healthiest food sources rich in vitamin d
Salmon is a popular fatty fish and also a great source of vitamin D. According to nutrient databases, one 3.5-oz (100-gram) serving of salmon contains between 361 and 685 IU of vitamin D (5). However, it is usually not specified whether the salmon was wild or farmed.
If you donât like fish, taking cod liver oil can be a good way to obtain certain nutrients that are hard to get from other sources. At about 450 IU per teaspoon (4.9 ml), cod liver oil is an excellent source of vitamin D. Itâs been used for many years to prevent and treat deficiency in children (13, 14).
