The Importance Of Vitamin D In maintaining Health
We might not be much concerned about getting enough vitamin D in the summertime, but we should never assume that we have enough levels of this vitamin in our bodies to keep us healthy. Vitamin D is a fat-soluble vitamin and has a crucial role to play in all our physiological functions. However, technically, it is not a vitamin and can be considered a very powerful steroid hormone with a complex role in protecting more than two thousand genes in our body from expressing negative traits.
In the optimal levels, vitamin D may be capable of preventing many diseases. This means that if you have a genetic predisposition to a particular disease, you may prevent it by optimizing the levels of vitamin D in your body.
Vitamin D3 Vs Vitamin D2
Even though there are numerous forms of vitamin D, the most common and popular ones are vitamin D2 and vitamin D3. These are different in many ways. The main differences between these two forms of vitamin D are:
- Vitamin D3 has very high absorption rates when compared to vitamin D2. In fact, the absorption rate of vitamin D3 is seventy percent more than that of vitamin D2.
- Vitamin D3 can stay in the fat cells in our body for longer times and can help us through winter times when we aren’t much exposed to sunlight.
- Vitamin D3 is mainly obtained from sunlight, but can also be found in cod liver oil and fatty fish.
Vitamin D2 is commonly used to fortify foods and is the main type of vitamin D found in health supplements. However, many pharmaceutical companies and compounding pharmacies are now moving to vitamin D3.
Vitamin D is essential for our body and can offer protection against acute respiratory infections. This might explain why seniors, the demographic group that is the most deficient in this vitamin, are seriously affected by the COVID-19 infection.
Optimizing Vitamin D Levels
The main way to know that you have optimal levels of vitamin D in your body is by testing. As per the experts, it is best to test the levels of vitamin D in your body in the fall months when the levels can be the highest and in winter months when the levels can be the lowest. With these two values, you will be able to safely find the vitamin D supplementation needs of your body.
