resB Lung Support Probiotic is the #1 physician-recommended lung health supplement, developed by pulmonary physicians to target the connection between your gut and lungs.

Formulated with three clinically studied Lactobacillus strains plus Ayurvedic botanicals (vasaka, turmeric, holy basil), this probiotic works on the gut-lung axis to support respiratory function, ease seasonal symptoms, and improve breathing.

Clinical trials showed participants experienced significant improvements in lung function (forced expiratory volume) within 30 days. Some people report breathing benefits within 6 days, others after 60, but physicians recommend consistent use for 3-4 months.

It's especially helpful for anyone dealing with persistent cough, seasonal sinus issues, shortness of breath, or breathing-related sleep disturbances.
