Vitamin D (scientifically known as calciferol) is a fat-soluble vitamin that is one of the essential nutrients for our body. From maintaining our bone health to helping in the absorption of calcium, magnesium, and phosphorus, vitamin D plays a huge role in maintaining our overall health. We get a lot of our daily requirement of this essential micronutrient from the sun's rays. However, it might not always be possible to go outside and stand under the sun to get those requirements fulfilled. That is where vitamin D-rich foods come in. Here you will find 15 foods that will ensure you never lack this vitamin in your body. Let’s go!

Salmon - Salmon is one of the best sources of vitamin D. Around 3.5 ounces of this high-fat-contained fish is said to fulfill 80% of the daily recommended dietary allowance of vitamin D in a healthy human being. Although wild salmon has a higher vitamin D content than farmed salmon, they are both great sources of vitamin D and should be incorporated into one’s diet to fulfill the requirements.
Cod Liver Oil - Cod liver oil is one of the best food sources of vitamin D. It has extensive consumption, especially among people who do not like to take fish.

Depending on whether they grow in sunlight or are grown in the dark, the vitamin D content might vary, the former one being a much better source of this vital component.
