Can I take resB Lung Support Probiotic for COPD, Bronchitis, Pulmonary Fibrosis, or Asthma?

The resB Lung Support Probiotic formula is based on more than 10 years of rigorous research to support healthy respiratory structure and function, healthy digestion, and the immune system while keeping everyone in mind. Our ingredients and supplements have been extensively studied in many settings, including physician-supervised preclinical and clinical trials in specific conditions.

That said, no supplement can make claims regarding any specific disease diagnosis. We recommend you check with your doctor or pharmacist before starting any new dietary supplement.

Is it safe to take with other supplements and medications for COPD, Asthma, etc?

While there are no known contraindications with resB Lung Support Probiotic and any over-the-counter or prescription medications, we encourage you to consult your primary care physician or pulmonologists before adding new supplements to your routine.

Additionally, if you are taking an antibiotic, take resB Lung Support Probiotic at least 1 to 2 hours before or after your antibiotic dose. This is to ensure your antibiotic doesn't kill the probiotic bacteria in resB Lung Support Probiotic before they have a chance to work!

The formula is processed precisely for extended stability and longevity, rigorously tested for the most stringent quality, purity, and safety measures, and delivered through a temperature-controlled supply chain to ensure a consistent live CFU (Colony Forming Unit) count in every capsule.

How long does it take to see benefits?

While people often report gut health benefits as early as their first week of taking resB Lung Support Probiotic, the systemic benefits can take longer.Some customers report breathing benefits within 6 days, others after 60. This variability can be attributed to many factors, including the importance of continuous daily use and the fact that some people constantly think about their lungs while others breathe without much thought. Our physicians recommend consistent use for 3-4 months.
