Effect of A2 milk on Exercise Performance and Severity of EIB in Asthmatics

01 January 1970

The aim of this study is to investigate the effect on airway health, health status and exercise performance in athletes with asthma and exercise induced asthma who switch to using A2 milk from regular cows’ milk. Regular Cow’s milk contains a mix of A1 and A2 protein. Previous research has shown that A1 protein may affect gut transit and inflammation. Work in other areas has demonstrated that inflammation in the gut may translate to the lungs and impact on asthma severity.


  • We would like to recruit female and male athletes aged between 18-45 years with a clinician’s diagnosis of asthma or exercise induced asthma. Potential participants should be otherwise fit and healthy and already engage in endurance training (three times per week or more). Please contact me for more information on the inclusion/exclusion criteria.
