Vitamin D3 for a Better Immune System

Vitamin D3 for a Better Immune System

There are mainly two forms of vitamin D that differ in their food sources. Vitamin D2 comes mostly from fortified foods and plant sources, whereas vitamin D3 is only found in animal-sourced foods. 

Your skin produces vitamin D3 when it is exposed directly to the sunlight. The UVB radiation coming from sunlight stimulates the formation of vitamin D3 from your skin using the compound 7-dehydrocholesterol. 

If you usually spend your time outdoors, without applying sunscreen, you might get all the vitamin D your body requires. You can also use supplements or choose a right plant-based diet to obtain sufficient nutrients for the working of your body.

The Basics of Vitamin D

Vitamin D is a rare type of vitamin because it performs more like a steroid hormone rather than a dietary aid, which is not available in most foods like other vitamins. 

Although, vitamin D can be obtained primarily from the sun, which is why it is termed as ‘sunshine vitamin.’ When your skin absorbs the sunlight, it synthesizes the incoming UVB rays into vitamin D.

You should always limit the prolonged exposure to the sun, because getting adequate amounts of sun rays to help you to ensure that your body has good stores. It is essential because vitamin D has an immense effect on the mood, and can help to reduce the symptoms of depression. It is also a fat-soluble vitamin that plays a significant role in the way the body absorbs other vital nutrients. 

But some places around the world are not as sunny as Florida or California, which limits the access of sunlight, and because the process of synthesization also varies from person to person, everyone is not capable of consuming perfect amounts for optimal well-being. In such cases, supplements come into play.

The significant benefits of Vitamin D3

Vitamin D3 can have a considerable impact just like other different genes within the body and plays a direct role in many aspects of health that many people might not realize. 

The receptors of vitamin D are found in mainly every cell. When the vitamin D binds to a receptor, it turns the genes on and off, making the changes at the cellular level. 

Several studies proved that this process eliminates the cancer-causing bacteria, and turns on the immunoprotective genes, and tells the cells which minerals and vitamins to absorb. It has a significant impact on several essential body processes.

Bone Health

A proper intake of vitamin D3 is a result of strong bones because it helps to control and regulate the body’s ability to absorb calcium and phosphorus, the two different compounds that provide strength and density to the teeth and the skeletal system. 

So, this nutrient is essential for those people who are suffering from osteoporosis. Several studies proved that vitamin D and calcium together could help to build strong bones in women after the menopause. People with low levels of vitamin D may also need Vitamin D3 supplements to ensure the accurate working of the body. 

Insulin Control

Vitamin D3 triggers the pancreas and stimulates the process to produce insulin within the body. It is critical for regulating blood sugar levels more effectively and helps people suffering from diabetes to control the disease better. 

It helps to reduce the insulin resistance in several surrounding tissues, and ultimately reduces the release of excessive insulin, which is responsible for the increased blood sugar level. Overall, it increases insulin sensitivity.

Lower the Blood Pressure

According to a study, it is found that people dealing with high blood pressure experienced a drop when the vitamin D3 levels were increased in their bodies. D3 effectively reduces the level of renin, which is an enzyme released by the kidney that has a significant impact on the blood vessels.

An overactive blood pressure body can lead to massive high blood pressure, and vitamin D3 can help you to eliminate any risk of hypertension.

Prevents Possible Cancer

Some evident studies state that increased levels of vitamin D3 can help you to slow the development of prostate tumors, while some other promise that combining this nutrient with more fiber can also reduce the risk generating polyps, which can lead to massive colon cancer. 

Another useful combination is calcium and vitamin D. A study found out that when postmenopausal women supplemented with these two nutrients, the chances of developing cancer reduced by 60 percent.

Vitamin D is frequently studied for its effects on breast cancer. In research, 166 women were treated, and nearly 70 percent were found with low levels of vitamin D. Although it is not proved that this nutrient is useful for curing breast cancer. 

Heart Health

The functioning of the heart can also be affected by the presence of vitamin D. in research; a low level of vitamin D was correlated to an increased risk of a heart attack. Although, there is no particular reason for that, while some researchers state that vitamin D acts as a ‘heart tranquilizer,’ which keeps the heart muscles from growing too large and improves cardiovascular endurance. 

It ultimately prevents the thickening of the walls of the ventricles, which can block the blood flow and increase the risk of a heart attack. Excessive stress can also affect your heart health. 


One of the essential benefits of vitamin D3 is its influence on the mood. Numerous people agonize from seasonal affective disorder, and mostly feel better while consuming sunlight because of the process of synthesis with direct exposure to UVB sun rays. 

Increased level of vitamin D can effectively help you to decrease the indications of clinical depression. You may require other treatments as well, but first, you need to ensure that proper immersion of vitamin is critical for your body. 

Help Hair Growth

Vitamin D3 might help you to maintain the thickness of your hair, and prevent existing hair from falling permanently. Due to this fact, getting an adequate amount of vitamin D can support your hair growth and regrowth.
