Thanks for your question on Healthcare Magic. I can understand your concern. Yes, along with vitamins you should add anti oxidants. Anti oxidants are very useful in emphysema especially in limiting progression of disease. Newer pulmonary (lung specific) anti oxidant, Picnovit (pine bark extract) is now available. And it is having excellent positive effects in emphysema patients. So you can add this without any harm. Also enroll in pulmonary rehabilitation center where chest physiotherapy and deep breathing exercises are done. These will also enhance your lung functions and reduce breathing difficulties. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
