Consider this treatment:

Unclear impact. Only 3 small researches were done, showing some benefits. More research is needed. Side effects seem negligible, therefore it makes sense to try taking 1-2 grams of Vitamin C one hour before exercise and to see if it helps.

Doctors Say That Curefacts.com -  Tooltip icon

Exercise-induced breathlessness is common in Asthmatic patients, but also occurs to non-Asthmatic people. If you suffer from wheezing, shortage of breath and coughing during and following physical practice, ask your doctor to check if you are asthmatic. If you are not - try using a Ventolin HFA inhaler 30 minutes before practice, and see if it helps you.

Any excess of Vitamin C (Ascorbic acid) is evacuated from our body through the urine. This makes vitamin C pretty safe even in high dosages.
