First time heard this product was in the Pharmacy about 1year ago. I have bought one just want to try because of my old boy has Asthma, he was breathes hard at night. Since my boy eating this product, his breathing is much better. Since then, I never stop. Now, my younger boy also eating this product too. I also would like to thanks healthy post offer us this product for better price, quick delivery ( received product within one day) and good service!
