Generally speaking, all probiotics perform through the same mechanism - fundamentally targeting pathologic changes in bacterial species. However, probiotics for lung health focus on reducing inflammation by impacting the lung-gut axis.
Some probiotic products for lung health may also contain additional products, such as herbs, that have been shown to improve lung function in studies. It is important to note that while respiratory probiotics act on different pathways than most respiratory-care medicines, some research findings suggest there is a risk of herbal dietary supplements interacting with prescription medications.
It’s also important to pay attention to the probiotic strains in a supplement if you consider taking more than one probiotic blend. In theory, if the supplements you are taking contain different bacteria or target different organ systems, then it’s OK to take other probiotic supplements. Tolerance typically depends on the dose and the individual’s sensitivity factors; however, side effects such as abdominal pain, diarrhea, and gastroesophageal reflux have been associated with large daily doses.
Overall, it’s best to discuss with your doctor before incorporating a new probiotic into your daily regimen, and you should always discuss any questions or concerns with your healthcare provider.
