With the Covid-19 pandemic, we all started talking more about our immunity and about each vitamin than usual, right? One of the names we hear most often is vitamin D. Some say that if vitamin D is low, it is easier to develop Covid, and if it is, it becomes severe. Others say that these are just stories. What is the real connection between vitamin D and Covid-19? Let's understand this precisely and simply.

First of all, what is vitamin D?
Simply put, vitamin D is an essential nutrient for our bodies. In fact, it also acts as a hormone. Vitamin D is essential for several key functions in our bodies.
- To strengthen bones: Vitamin D helps the body absorb the calcium we get from food. Without vitamin D, no matter how much milk we drink or calcium pills we take, our body will not absorb it properly. Therefore, vitamin D is essential for a healthy, strong skeletal system.
- Immune system: Vitamin D also helps in the functioning of the immune system, which helps our body fight diseases. That is, it helps in increasing the ability to resist diseases.
The main way we get vitamin D is through sunlight . When our skin is exposed to sunlight, a type of cholesterol in the skin is converted into vitamin D. In addition, we can also get some vitamin D from some foods.
However, many people do not have enough vitamin D in their bodies. This deficiency is especially common in older people, those who do not eat a balanced diet, and those with darker skin tones (darker skin has a harder time making vitamin D from sunlight).
The real link between vitamin D and COVID-19
Okay, now let's get to the most important part. Is there a link between vitamin D deficiency and COVID-19?
Several studies have shown that people with low vitamin D levels are at a slightly higher risk of contracting COVID-19, and if they do get infected, their condition may be more severe. This may be because vitamin D strengthens the immune system and controls inflammation in the body.
But there's something very important that we shouldn't get confused about here. While people with low vitamin D are at higher risk, there's still no scientific evidence that taking vitamin D pills can prevent you from getting COVID-19, or that it will help you recover faster if you do.
That means vitamin D isn't a magic bullet for COVID-19. But maintaining healthy vitamin D levels in your body can help keep your overall immune system in good shape.

Check Availability →Vitamin D deficiency and other diseases
Vitamin D deficiency can increase the risk of not only COVID-19, but also a number of other diseases. Some of these can even make COVID-19 more severe.
| Medical condition | Relationship with vitamin D deficiency |
|---|---|
| Heart disease and high blood pressure | It has been suggested that low vitamin D levels increase the risk of these diseases. |
| Diabetes | Research has shown a link between vitamin D deficiency and diabetes. |
| Some types of cancer | There is evidence that it may affect the risk of cancers such as colon, prostate, and breast cancer. |
| Immune system problems | It can be linked to frequent infections and conditions such as multiple sclerosis. |
Now, think about it, we know that people with conditions like obesity and diabetes are at a higher risk of severe COVID-19 if they get it. And these conditions are also associated with vitamin D deficiency. So it's all connected.
So how do we get enough vitamin D?
The best and most natural ways are sun exposure and eating foods rich in vitamin D.
Vitamin D from sunlight
It is very good to expose yourself to the sun for at least 15-20 minutes a day, about three days a week. Especially the morning sun is best for this. You don't need to expose your entire body, just your hands, feet and face are enough.
Vitamin D from food
Try adding these foods to your diet:
- Oily fish like salmon and sardines
- Red meat (such as beef)
- Egg yolk
- Fortified foods with added vitamin D (see the label of some milk powders, yogurts, etc.)
If you take vitamin D supplements...
Vitamin D pills are another option, but you have to be very careful here.
Never take vitamin D pills from a pharmacy at your own discretion. Always consult your doctor and, if necessary, take only the dose he prescribes, at the prescribed time.
Taking too much vitamin D can also be very harmful to the body.
What happens if vitamin D is too high?
If you take too much vitamin D, it can become toxic. In this case, the calcium level in the blood increases unnecessarily. If this happens, symptoms such as these may occur.
| Symptom | Description |
|---|---|
| Nausea and vomiting | Stomach discomfort and vomiting. |
| Excessive thirst and frequent urination | This may occur due to effects on the kidneys. |
| Anorexia and constipation | Impaired functioning of the digestive system. |
| Weakness and memory loss | Increased calcium levels in the body can affect brain function. |
| Ataxia | This is a condition related to the nervous system. It can cause a slight slurring of speech or a clumsiness when walking. |
So, remember, like anything, too much vitamin D is not good.
