10 Benefits of Vitamin D3

do you have vitamin d deficiency

Vitamin D3 is vitamin D’s bioavailable form that people can get from some foods. The most common source of vitamin D is, however, sunlight. Vitamin D3 is naturally produced in the skin when it is exposed to the sun. This is the reason why vitamin D3 is also called the Sunshine Vitamin.

Although vitamin D3 is vital for several bodily functions, there are many people out there who don’t get enough of it – especially during the winter months. It is also important to note that sunblock inhibits the absorption and production of vitamin D3.

Today we are going to discuss some prominent benefits of vitamin D3 that aren’t known to many people. But before we talk about the benefits, let us show the problems vitamin D3 deficiency can cause and from where you can get vitamin D3.

Vitamin D3 Deficiency

In the past few years, doctors have started paying more attention to the issue of vitamin D3 deficiency and the health problems it can cause. Few of the most common problems that people may experience due to vitamin D3 deficiency include:

  • Pain in bones, leading to fractures
  • Weakness and muscles aches
  • Depression
  • Fatigue and feeling of malaise
  • Difficult walking

About 32% of adults and children are deficient. Several factors contribute to this, most of which are related to the sun. Some prominent factors that contribute to vitamin D3 deficiency include:


  • Using Sunscreen all the Time


You might think that going out into the sun with no sunscreen on is dangerous. However, by using sunscreen, you aren’t allowing your body to absorb direct sun rays to increase vitamin D3 production and absorption.

  • Spending a lot of Time Indoors

If you spend all your time indoors, you won’t be able to get any sunlight. Since the Sun is the major source of vitamin D3, you could experience vitamin D3 deficiency if you don’t go out in sunlight.

How to Get Vitamin D3

Vitamin D3 is only found in some foods. Dairy products, grains, and cereals contain vitamin D3 in large quantities which is why we recommend people who need more vitamin D3 to increase the intake of these foods. Eggs and fatty fishes including sardines, tuna, and salmon are other sources of this vitamin.

Supplemental vitamins can be taken to increase vitamin D3 intake. The recommend vitamin D3 intake is 1,000 IU per day. It is important that you first receive clearance from your physician. Vitamin D3 is a hormone and over-the-counter option, but it should still be administered with professional guidance. A doctor will perform a blood test to determine if you are deficient and need more concentrations of vitamin D3.

Benefits of Vitamin D3


  • Vitamin D3 Lifts the Mood Up


Our brain contains vitamin D3 receptors. So if vitamin D3 levels in our brain are low, it can lead to mood issues, as this nutrient is required to help the human body for creating neurotransmitters. Neurotransmitters help regulate your mood. Therefore, you should consider eating more vitamin D3 rich foods if you often find yourself in a bad mood.


  • Vitamin D3 Protects the Heart


Recent research has revealed that vitamin D3 may help regulate blood sugar, ultimately supporting heart health in the long term.


  • Vitamin D3 Strengthens the Bones


Vitamin D3 helps regulate phosphorous and calcium in our body and this leads to strong and healthy bones. This vitamin is also required for bone formation and growth. People who have a vitamin D3 deficiency are at a higher risk of osteoporosis and bone fractures.


  • Vitamin D3 Helps Preservers the Memory


Do you remember us saying that there are vitamin D3 receptors in the brain? Well, when those receptors don’t get enough vitamin D3, they are more likely to malfunction which increases the risk of dementia.

In a recent study, it was found that the people with vitamin D3 levels below 25 were four times more likely to suffer from cognitive impairment than those who had vitamin D3 levels 75 and above.  So if you want to preserve your memory in the old age, we recommend you increase your vitamin D3 intake.


  • Vitamin D3 Makes People More Immune to Diseases


Our immune system is made up of a number of different cells and these cells need vitamin D3 for fighting disease-causing pathogen-like viruses. If you have vitamin D3 deficiency, you are likely to get sick more often than normal and may even struggle to fight infections properly. So if you get sick more often, get yourself checked by a doctor for vitamin D3 deficiency.


  • Vitamin D3 May Help Prevent Cancer


Some researchers have found that vitamin D3 is linked to cancer prevention, specifically breast, colon, and prostate cancers. Since this vitamin helps to regulate the growth of cells, it could stall the development of new cells in cancerous tissues.

However, more research is required before a credible relationship can be established between vitamin D3 intake and cancer prevention.  


  • Vitamin D3 May Help Calm Blood Pressure


Some reports have suggested that vitamin D3 can help module the system that controls our blood pressure. However, there is no credible research to support this.


  • Vitamin D3 Soothes the Stomach


Vitamin D3 modulates the inflammatory process in our gut. People who have lower levels of this vitamin often suffer inflammatory bowel diseases like Irritable Bowel Syndrome (IBS). Lower levels of vitamin D3 can lead to more inflammation in our digestive tract which may exacerbate IBS symptoms.


  • Vitamin D3 May Help with Diabetes


A few studies have shown that vitamin D3 helps regulate insulin levels. This can help with the management of diabetes. Vitamin D3 can contribute to balancing blood sugar by supporting insulin actions and promoting the health of pancreatic cells.  


  • Vitamin D3 Helps with Gym Performance


Vitamin D3 helps improve muscle strength, physical performance, and balance. This means that if you want to do better at the gym and get fit quickly, you should consider increasing vitamin D3 intake.

We have shown you the benefits of Vitamin D3. Now, if you think you have vitamin D3 deficiency, get yourself examined by a doctor, and do what they tell you to get your vitamin D3 levels in the appropriate range.
