Does Vitamin B12 Help with Allergies?
Allergies are an overreaction of the immune system to certain substances, such as pollen, animal dander, dust mites, and certain foods. Allergies can cause a wide range of symptoms, including sneezing, nasal congestion, runny nose, itchy and watery eyes, coughing, and skin rashes.
Vitamin B12 is an essential nutrient that helps the body to produce red blood cells, maintain nerve cells, and make DNA. It is also thought to have anti-inflammatory properties, which makes it a potential remedy for allergies.
Anti-inflammatory: Refers to a substance or agent that reduces inflammation, or swelling, in the body.
Although the evidence is limited, some research suggests that taking vitamin B12 supplements may help reduce allergy symptoms. For example, a small study from 2019 found that vitamin B12 supplements reduced rhinitis symptoms in people with allergic asthma.
In addition, a small study from 2010 found that taking a combination of vitamin B12 and other B vitamins reduced symptoms of allergic rhinitis, such as nasal congestion and sneezing.
