Vitamin D is an essential nutrient that all people need, and is responsible for important functions such as calcium absorption for proper bone development in children. There are many conditions linked to a lack of Vitamin D such as mood disorders and hypertension.
The problem is, many people in the U.S. have insufficient levels of D because it mainly comes from the sun, and many Americans spend most of their time indoors (especially in winter).

It sounds pretty nasty, but luckily it comes in soft pill form to make it easier to swallow (just don’t bite down). Cod liver oil is often mistaken for fish oil when people are looking for Vitamin D content, but they’re not the same thing, noted Livestrong.
Although both have their health benefits, only cod liver oil contains both Vitamins A and D, which are stored in the fish’s liver as the name suggests. Livestrong notes that too much cod liver oil can harm you. The maximum intake of Vitamin D for adults should be 2,000 IU per day (although other sources say 4,000 IU, but it might be best to be conservative). Too much D can cause sickness—and too much Vitamin A can cause a nasty array of side effects as well, including liver problems.
