Do you have a Chronic Cough? We Can Help.

Try B12 Nitro from XCAP, it may just get rid of your cough.

A new study shows that deficiency of vitamin B12 might be a factor in unexplained chronic cough and dysfunction of the pharynx and larynx.

Vitamin B12 supplements improved histamine thresholds and significantly raised the cough threshold in patients with vitamin deficiency.

The study, presented here at the World Allergy Organization XXI World Allergy Congress by Giuseppe Guida, MD, from Allergy and Clinical Immunology, University of Turin and Mauriziano Hospital in Italy, examined the effect of histamine on the cough threshold and the upper and lower airway responsiveness in patients with unexplained cough.

The current study looked at 40 patients with chronic unexplained cough. Of these, 25 were found to have vitamin B12 deficiency (serum levels <300 pg/mL); the control group consisted of 15 chronic-cough patients with no detected nutritional deficiency.

Patients deficient in vitamin B12 were found to have significantly lower threshold values for extrathoracic airway and cough, but bronchial thresholds did not differ from those of control subjects.

Vitamin B12 supplementation improved histamine thresholds (reduced hyperresponsiveness) in vitamin-deficient patients without significantly changing them in control subjects. This improvement was found in bronchial (P < .01),
extrathoracic airway (P < .001), and cough (P <.01) thresholds.

“Supplementation is certainly very easy to perform”, Dr. Guida told Medscape Allergy and Immunology. “So, theoretically, there is a good way to treat this disease.”

“Of course, we need more data to confirm the fact that there is a strong association between these 2 cofactors [chronic cough and the B12 deficiency],” acknowledged Dr. Guida. However, “if this is the case, [this] could be a
very easy way to help these people,” he said, “especially because they are older and it’s a very easy medication to [administer].”

Try 1-3 B12 Nitro lozenges from XCAP per day.
