The Bottom Line The D3 form is found in fatty animal-sourced foods, such as fish oil and egg yolk. Your skin also produces it in response to sunlight or ultraviolet light. In contrast, vitamin D2 comes from plants. Interestingly, vitamin D3 appears to be more effective at increasing levels of vitamin D in the blood.

Reference Range. The major circulating form of vitamin D is 25-hydroxyvitamin D (25(OH)D); thus, the total serum 25(OH)D level is currently considered the best indicator of vitamin D supply to the body from cutaneous synthesis and nutritional intake. The reference range of the total 25(OH)D level is 25-80 ng/mL.
