Allergy is an exaggerated response in the body to substances that are typically harmless. These foreign substances can trigger reactions like itching, sneezing, and shortness of breath due to an overactive immune system.

Vitamin C is widely believed to boost immune function. So, is it true that taking vitamin C can help alleviate allergies?

Vitamin C to Relieve Allergy

Allergies occur when the immune system reacts to allergens, which are harmless substances that the body mistakenly identifies as harmful. When exposed to these allergens, mast cells from the immune system release histamine to fight what it perceives as foreign proteins.

The release of histamine can lead to common allergic symptoms such as:

• Runny nose

• Sneezing

• Watery eyes

• Itching

• Rash

• Shortness of breath

• Swelling

Vitamin C, or ascorbic acid, plays an important role in supporting the immune system. Research has shown that vitamin C acts as a natural antihistamine and antioxidant, which can help alleviate allergic reactions.

Unlike conventional antihistamines that block histamine receptors, vitamin C works by reducing the amount of histamine the body produces in the first place.

One study found that a 2-gram dose of vitamin C could reduce histamine levels by up to 38%, which helps reduce allergic reactions. Higher doses may be even more effective in alleviating allergy symptoms.

An observational study explored the effects of vitamin C infusions on people with skin or respiratory allergies. The results indicated that vitamin C infusions could reduce symptoms like sneezing, runny nose, itching, and sleep disturbances by as much as 97%.

Another study tested the effectiveness of a vitamin C nasal spray in 60 individuals suffering from allergy symptoms like sneezing and a runny nose. The spray reduced symptoms by up to 74%.

While vitamin C has been shown to alleviate respiratory symptoms from seasonal or environmental allergies, such as those caused by mold, dust, and pet dander, there is no evidence to suggest it can prevent seasonal allergies. Further research is needed to fully understand the role of vitamin C in preventing and treating allergic reactions.

Moreover, vitamin C is not proven to prevent or treat food allergies, which tend to cause more severe reactions than seasonal allergies. Food allergies typically affect the digestive system, skin, eyes, throat, and respiratory system. If you experience a food allergy reaction, it’s crucial to seek medical attention immediately for proper treatment.

How to Treat Allergies

To prevent allergic reactions from worsening, the most effective method is to avoid exposure to allergens. Allergy treatment depends on the symptoms experienced and may include:

• Antihistamines

• Nasal sprays

• Decongestants

• Asthma medications

• Immunotherapy

• Nasal saline irrigation

Vitamin C can help alleviate some allergy symptoms, but it should not be the primary treatment for allergies. Furthermore, not all allergy symptoms, especially those related to food allergies, can be treated with vitamin C. If you experience an allergic reaction, consult a doctor for appropriate care.
