If you have Chronic Obstructive Pulmonary Disease (COPD), we recommend that you speak with your doctor before using ARK Drops or any other natural remedy. While ARK Drops may be able to improve breathing and alleviate some symptoms associated with COPD, it is important to ensure that any new supplement or remedy you are considering is safe and appropriate for your individual needs. However, we have received a lot of feedback from customers who suffer from COPD and have found that ARK Drops helps tremendously in improving their breathing and reducing symptoms. Your doctor can help you determine if ARK Drops is right for you and can provide guidance on the proper dosage and usage.
