Difference between Vitamin D2 and D3
Vitamin D is a vital nutrient that plays a critical role in maintaining healthy bones, teeth, and muscles. It also has essential functions in regulating immune, cardiovascular and neurological systems. Vitamin D2 and D3 are two forms of vitamin D.
Vitamin D2
Also known as ergocalciferol, Vitamin D2 is a plant-based form of vitamin D. It is commonly found in mushrooms, fortified cereals, and other plant-based foods.
Vitamin D2 requires a higher dose when compared to D3 to raise blood serum levels, and it has a shorter shelf life. It can also be less effective than vitamin D3, although it is still beneficial to take.
Vitamin D3
Also known as cholecalciferol, vitamin D3 is the human body’s preferred form of Vitamin D. It is produced when the skin is exposed to sunlight, and it is also found in animal-based foods like eggs, oily fish, and dairy products.
Vitamin D3 is more potent, stable, and bioactive than vitamin D2. It is also more readily absorbed and utilized by the human body. Vitamin D3 is also found in supplements to ensure that people meet their recommended intake.
Which is better – Vitamin D2 or D3?
While both D2 and D3 are vitally important for health, research shows that vitamin D3 is more effective and beneficial for the human body.
Vitamin D3 is important for increasing calcium levels in the bones, and recent studies confirmed that vitamin D3 supplementation may help prevent fractures and falls in older adults.
Therefore, it is recommended that people get most of their vitamin D3 from exposure to sunlight or consuming animal-based foods. But, if someone needs to supplement their vitamin D, they should choose vitamin D3 for optimal health benefits.
Conclusion
In conclusion, vitamin D2 and D3 are two forms of vitamin D. Vitamin D3 is the preferred form of Vitamin D as it is more effective, potent, and beneficial for the human body. Therefore, it is important to prioritize getting sufficient amounts of vitamin D3 either through sun exposure, diet or supplementation for optimal health.
