I have been taking Better Lungs for a year now. I had Covid, and didn't feel right after healing, still occasionally coughing. Burning in chest, then came across this product and thought why not try it? It works great, and does exactly what it says it does. I'm also a smoker and notice a huge difference in my overall breathing, hardly any coughing, helped with allergies. Just a great product all around. I'm so glad I found this product.
