Some cereal brands are fortified with many important minerals, including vitamin D. For instance, a package of fortified, unsweetened oatmeal would provide around 40 to 50 IU, which can meet a significant part of your recommended daily intake. You can go for more heavily fortified options, but they tend to be more expensive. Keep in mind that the levels of vitamin D in cereal tend to be lower than natural sources, such as fish or egg yolk. However, they can still a good option to improve your intake, especially when you are a vegan. In addition, these products are packed with fiber, which can aid in digestion and prevent constipation. Since there are many brands and products available, keep in mind to read the list of ingredients carefully before purchasing. [15]
