The cause of a runny nose is not what most people think, in fact there are very few people who actually know what the root cause of a runny nose really. Find out what is really causing your runny nose, and how to eliminate it to avoid having to carry around a box of tissues everywhere you go.


What People Think Causes A Runny Nose:

What Really Causes A runny nose

If you ask most people what causes a runny nose they will say its seasonal, like the time of year is the most important factor as to whether or not you suffer from a stream of mucus coming out of your face.

The most notable times of the year that lead to this are spring and fall. During these times there are rather rapid changes in the environment around us. Some of the most notable that people will say are causing a runny nose are pollen, dust, or changes in biometric pressure. These are not the cause, but rather triggers that initiate the process that creates the problem. The real cause lies much deeper inside you....

What Really Causes A Runny Nose:

The Real Cause of a runny nose

The root cause of a runny nose comes down to one thing - nutrient deficiencies. There is one nutrient that is the most notable for its role in a runny nose, vitamin D.

Vitamin D is a fat soluble vitamin that can be synthesized in humans when the skin is exposed to the uv rays of the sun. When there is a lack of sunlight, vitamin D synthesis will go down, and over time if there is not a sufficient amount of vitamin D coming from the diet or from supplementation a deficiency will develop.

The development of a vitamin D deficiency is most common during the winter. The days get shorter limiting the amount of sunlight that is available in combination with more clouds being present blocking the exposure to uv rays. This is one of the side effects of SAD, also known as seasonal affective disorder. SAD is a phenomenon that shows increases in depression during seasonal changes, especially from summer to winter. This makes sense as a vitamin D deficiency becomes more prevalent depression has been shown to increase. This meta-analyses even showed that when supplementing with vitamin D there were favorable effects on depressive symptoms comparable to that of anti-depressant medication.

If you have paid attention to the cycle of your runny nose it is most likely worse when spring time hits. You just spent an entire winter developing a vitamin D deficiency form a lack of sunlight, and combine that with the triggers present in spring time like excess pollen and dust, and you have the perfect storm for a runny nose.

Researchers have shown that vitamin D plays an important role in this process, and having sufficient vitamin D levels plays a major role in your body’s ability to overcome this issue.

Foods High in Vitamin D:

At UMZU we always recommend taking steps to cover your nutrient needs with food first, then using supplementation to cover the leftover gaps. Some of the best foods that are high in vitamin D include:

  • Egg Yolks
  • Beef Liver
  • Sardines
  • Cod Liver Oil
  • Mushrooms

Outside of these foods there are not many sources of vitamin D that are naturally available. It is also hard to eat enough of these on a daily basis to cover your vitamin D needs. For example, an egg yolk only contains 37 IU of vitamin day while the RDA for vitamin D is around 600 IU for young adults. This would equate to a little over 16 eggs on a daily basis. Because of this, supplementing with a little extra vitamin D when you are not getting a sufficient amount of direct sun exposure can be extremely beneficial.

For the average adult supplementing with 400 IU of vitamin D daily and getting the rest from sunlight and food is the best course of action. Make sure that when you are purchasing a vitamin D supplement it is not suspended in a nasty oil like cottonseed or sunflower oil. Instead look for a high quality supplement that is suspended in coconut or MCT oil.


Vitamin D is an essential nutrient, and plays a role in many physiological functions. A vitamin D deficiency can show itself in many different ways, and one of the most notable is a runny nose.
