Vitamin D

Found In

Vitamin D can be found naturally in cod liver oil, salmon, swordfish, tuna fish, sardines, beef liver, and egg yolk. Few foods are naturally rich in vitamin D, but we can increase our intake via certain fortified foods and supplements.

Nutrient Form

We use vitamin D in the form of cholecalciferol (also known as vitamin D3). Some experts cite vitamin D3 as the preferred form as it is naturally produced in the body and found in most foods that naturally contain the vitamin.*
