Nasal Allergies, Fasting and Serrpapeptase


by Nils Osmar. March 6, 2022

Nasal allergies are caused in part by an overreactive immune response. People who suffer from them often try medical and herbal remedies, some with more success than others. According to this 2014 study, fasting can be effective at lowering the hypersensitivity that makes us more allergic reactions.

From the study: 

The present study clearly demonstrated that food deprivation attenuated local and systemic immediate hypersensitivity symptoms. This attenuation was significantly correlated with the duration of food restriction and increases in blood D-BHB concentrations…

Type I allergy is an immediate hypersensitivity reaction that is characterized by allergen-induced mast cell degranulation and is followed by the immediate release of the chemical mediator histamine from mast cells stored in vesicles, which leads to inflammation, smooth muscle contraction, and vasodilation reaction… To further investigate the relationship between D-BHB and allergic reactions, we focused on the effect of D-BHB on mast cell activation.”

About Serrapeptase

Serrapeptase is an enzyme which clears protein fragments from the blood. It has been found to also help with the overproduction of mucus, which is often associated with nasal allergies. According to this Healthline article:

Serrapeptase may increase the clearance of mucus and reduce inflammation in the lungs in people with chronic respiratory diseases (CRD)…. In one 4-week study, 29 people with chronic bronchitis were randomly assigned to receive 30 mg of serrapeptase or a placebo daily (16).

Bronchitis is one type of COPD that leads to coughing and difficulty breathing due to the overproduction of mucus. People who were given serrapeptase had less mucus production compared to the placebo group and were better able to clear the mucus from their lungs (16).

The authors noted though that further studies are needed to validate the effectiveness of serrapeptase.

My experience

Speaking anecdotally, I’ve found fasting to be a life saver (metaphorically speaking) during allergy season. My allergies were flaring up yesterday, resulting in sneezing, stuffiness, itchy eyes and sensitivity to light. I noticed that they got worse after a meal.

Today’s my 36 hour fasting day. No food, just coffee in the morning and white tea this afternoon.

My only supplement so far has been serrapeptase, which cleans protein fragments (which can trigger allergies) from the blood.

My morning was great; no allergic symptoms. They started flaring up in the afternoon. Continuing to fast and taking more serrapeptase got rid of the symptoms again. (I took two capsules of Doctors Best serrapeptase at 7 a.m. and another two around 2 p.m.)
