Vitamin D, a fat-soluble vitamin, regulates bone development, promotes calcium absorption, and contributes to immune function in the body. It comprises a family of nutrients with similarities in chemical structure, containing multiple vitamins.

Particularly, vitamins D2 and D3 are the dominant types in your everyday diet. These serve to fulfil your body's vitamin D requirements. However, despite showing similarities in the chemical combination, they pose some distinct differences.

This article compares vitamin D2 vs D3, highlighting their differences.

What is Vitamin D2?

Ergocalciferol, commonly known as Vitamin D2, aids in calcium absorption within the body. It is used to cure hypophosphatemia, hypoparathyroidism, and rickets.

Individuals with a vitamin D allergy or elevated vitamin D or calcium levels should avoid consuming this nutrient. Furthermore, an excess of ergocalciferol or vitamin D2 can lead to severe or adverse deadly effects.

What is Vitamin D3?

Cholecalciferol, commonly known as Vitamin D3, is a supplement that boosts the body's calcium absorption. It is commonly prescribed for conditions like osteomalacia, vitamin D deficiency, and other associated disorders.

It is important to note that certain cholecalciferol or vitamin D3 supplements may contain components like peanuts, soybean oil, sugar, aspartame, or food pigments. Therefore, it is advisable to consult with a physician before using these supplements, especially if you have phenylketonuria, diabetes, or allergies.
