Breathing problem is usually related to the lungs being inflammed, either due to a chronic infection or the pollutants in the air. You will need Vitamin C, an antioxidant that will help build up the protective fluids in the lining within the lungs, which will in turn help build up your immune response and thereby eradicate your breathing problem eventually.
Depending on your current weight/height ratio, losing 25lbs at your age must be acted with due prudence and care, especially when it is not your body weight that causes your breathing problem. Like I have mentioned earlier, your breathing problem may largely due to a chronic infection or the pollutants in the air, and not because you are over weight.
To help in both your breathing and weight loss, detox is first the way to go. Only then should you begin with your regimen of health supplement for optimum absorption and effectiveness. Vitamin C is a must for your lungs as mentioned earlier. You will also need a good multi-vitamin to further boost your immunity which will also aid your system in effective weight loss.
I would highly recommend the books both by Dr. Ray D Strand, M.D. for the solutions you are seeking:-
“What Your Doctor Doesn’t Know About Nutritional Medicine May Be Killing You” - turbo charge your body’s natural healing power, start your anti-aging strategy now and protect yourself against the dark-side of oxygen, and
“Healthy For Life” - developing healthy lifestyles that have a side effect of permanent fat loss.
Happy reading!
