According to numerous studies, low vitamin D levels are significantly linked with an increased risk of chronic rhinitis and nasal inflammation, conditions known to cause a blocked nose. While a blocked nose can stem from many causes, growing evidence suggests that insufficient vitamin D can weaken the immune system and exacerbate inflammation in the sinuses.

Research suggests a strong correlation between low serum vitamin D levels and allergic conditions like allergic rhinitis. This means that what vitamin deficiency causes sneezing is most directly tied to insufficient vitamin D, which affects the immune system's regulation and inflammatory response.

According to some studies, a significant number of people with chronic rhinosinusitis have low levels of vitamin D, showing a correlation with more severe symptoms and nasal polyps. While no single vitamin deficiency is a direct cause, the link to a weaker immune response clarifies which vitamin deficiency causes a runny nose indirectly.

While excess mucus is often linked to illness, research shows certain food intolerances can trigger an overproduction. Understanding **what food intolerance causes mucus** can be a key step for those seeking to manage chronic symptoms through dietary choices.
