1.2. Vitamin D3 vs. Vitamin D2: What’s the Difference?
When exploring “what food has vitamin D3,” it’s important to understand the difference between vitamin D3 and vitamin D2. Vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol) are two forms of vitamin D that our bodies can use. The key differences lie in their sources and how they are metabolized:
| Feature | Vitamin D3 (Cholecalciferol) | Vitamin D2 (Ergocalciferol) |
|---|---|---|
| Source | Produced in the skin when exposed to sunlight; found in animal-based foods | Derived from plant sources, such as yeast and mushrooms |
| Production | Synthesized in human and animal skin | Produced by irradiating ergosterol, a substance found in fungi and plants |
| Metabolism | More effective at raising and maintaining vitamin D levels in the blood | Less effective compared to D3; may not raise vitamin D levels as efficiently |
| Food Sources | Fatty fish (salmon, mackerel), egg yolks, beef liver | Fortified foods, such as milk, cereal, and bread |
| Supplement Form | Generally preferred due to its higher efficacy | Often used in vegan supplements |
While both forms can increase vitamin D levels in the body, vitamin D3 is generally considered more effective at raising and maintaining these levels. A study published in the Journal of Clinical Endocrinology & Metabolism found that vitamin D3 was more potent than vitamin D2 in raising serum 25(OH)D concentrations.
