14 Jun 2023 --- Supplementation with a probiotic and herbal blend of four weeks increased the volume asthmatic patients could exhale in a one-second forced breath by 8.4%. The authors suggest this is due to increased short-chain fatty acids (SCFA) in the participants of the clinical trial. However, more extensive and longer-term studies are needed to confirm the correlation. The researchers determined that the supplement used – ResB Lung Support, developed by ResBiotic Nutrition – was safe and well-tolerated in healthy volunteers and asthmatic patients.
