Vitamins are very healthy for your body, and Vitamin D is one of them. The reason why we should be aware of its benefits is because many people don’t have enough vitamin D. For example, in America, one third of the people don’t have sufficient vitamin D, according to the Center for Disease Control and Prevention. Additionally, 8% of them are at risk for vitamin D deficiency.
Vitamin D is needed for enhancing calcium absorption. If a person lacks vitamin D, the bones might become soft. This disease is known as osteomalacia in adults and rickets in children. Additionally, vitamin D deficiency can lead to many different diseases. Here are some of them.
Type 2 diabetes
If the vitamin D levels are low, there is an increased risk of diabetes. That is because vitamin D has an important role when it comes to pancreatic cells that secrete insulin. Without this vitamin, your body will find it hard to regulate glucose levels.
Vitamin D is also used to regulate genes used for control growth, as well as survival of cells and differentiation. Without vitamin D, these processes won’t function and this can lead to cancer. It has been proved that people with higher levels of vitamin D also have lower risk of colorectal cancer.
Low vitamin D levels
Your body can lack vitamin D because of a number of reasons. For example, during winter, there are fewer hours of daylight. Your body needs sun in order to produce vitamin D. While sunscreen can protect you against the negative effects of UVB, it can also limit the production of vitamin D.
Additionally, people who are obese or overweight also have low vitamin D levels. It is harder to explain this one, because, according to scientists, this is not linked with their diet or physical activity levels. It is believed that this might be because vitamin D gets stored in the extra fat which means that the rest of the body does not get enough of it.
Do you need vitamin D?
While vitamin D has numerous benefits, you should make sure that your body needs additional vitamin D. In order to find out about your needs, a dna testing kit might be needed. A DNA test will show whether you truly need any supplements.
Genetics are important when it comes to your levels of vitamin D. The VDR gene can have many mutations that affect vitamin D. This gene encodes the vitamin D receptor. There are such receptors in the intestines and they are used to absorb calcium from the food you eat. It is also implicated in other roles such as cell proliferation.
