I've, always, had common colds, allergies or seasonal changes affect my respiratory system (for several weeks each time and needed meds to clear my chest). I began taking Respiratory Lung Health and I feel I've received new lungs! I do not have the respiratory difficulties anymore! Truly, this product has been a complete game-changer for me! Thank you Wayne Garland!!! (I've been taking them for 5 years now and have had no problems during this time!)
