The Difference In Vitamin D And Vitamin D3
Vitamin D is one of the essential vitamins that our body requires to perform various functions. It helps in maintaining healthy bones, teeth, and muscles. Our body produces vitamin D when it is exposed to sunlight. However, due to modern lifestyles and inadequate exposure to sunlight, many people have a vitamin D deficiency.
Vitamin D supplements are available in two forms, namely vitamin D2 and vitamin D3. Both these forms have some differences in their composition and properties, which we will discuss in this article.
What is Vitamin D?
Vitamin D is a fat-soluble vitamin that is naturally produced in our skin when it is exposed to sunlight. It can also be obtained by consuming foods that are rich in vitamin D, such as fatty fish, eggs, and dairy products.
Vitamin D is essential for the absorption of calcium and phosphorus in our body, which are necessary for the growth and maintenance of healthy bones and teeth. It also plays a vital role in regulating our immune system and reducing inflammation.
What is Vitamin D3?
Vitamin D3 is a form of vitamin D that is produced in our skin when it is exposed to UVB radiation from sunlight. It is also found in animal-based foods such as fatty fish, egg yolks, and liver.
Vitamin D3 is the most bioavailable form of vitamin D, which means that it is easily absorbed and utilized by our body. It has been found to be more effective in raising our blood levels of vitamin D than vitamin D2.
What is the difference between Vitamin D and Vitamin D3?
One of the main differences between vitamin D and vitamin D3 is their composition. Vitamin D2 is derived from plants, while vitamin D3 is derived from animal sources.
Another significant difference is their potency. Vitamin D3 is more potent than vitamin D2, which means that it is more effective in raising our blood levels of vitamin D.
Moreover, vitamin D3 has a longer half-life than vitamin D2, which means that it stays in our body for a longer time and provides a sustained supply of vitamin D.
Which one should you take?
Both vitamin D2 and vitamin D3 are effective in raising our blood levels of vitamin D. However, vitamin D3 is the preferred form as it is more potent and bioavailable than vitamin D2.
If you are deficient in vitamin D, it is recommended to take vitamin D3 supplements. However, it is always best to consult a healthcare professional before starting any supplement regimen.
Conclusion
Vitamin D is an essential vitamin that is required for various functions in our body. Vitamin D3 is the most bioavailable and potent form of vitamin D, which is derived from animal sources. Both vitamin D2 and vitamin D3 are effective in raising our blood levels of vitamin D, but vitamin D3 is the preferred form.
