The science behind Lactobacillus Acidophilus DDS1 for Acute Respiratory Infections

The science behind Lactobacillus Acidophilus DDS1 for Acute Respiratory Infections by Nutritionist Kay Ali

Acute Respiratory Infections (ARIs) are infections of the upper respiratory tract that impact normal breathing. The upper respiratory tract includes your nose, throat, pharynx, larynx, and bronchi. Both viruses and bacteria can cause ARIs. Infections include the common cold, sinusitis, pharyngitis, epiglottitis, and tracheobronchitis. There are a wide array of conventional treatments for ARIs. However, research indicates that probiotics may play a complimentary role in supporting respiratory health.

In a randomized, double-blind, placebo-controlled clinical trial, 240 children were enrolled to assess the short-term use of Lactobacillus Acidophilus DDS1 (combined with the Bifidobacterium UABLa-12 strain at combined 5 billion CFU/day) in the onset and management of Acute Respiratory Infections.[1]

Severity and resolution of reactions were secondary measurements of the study. The researchers concluded that the children taking the probiotic had a faster recovery period averaging five days. What’s more is, the severity of symptoms was significantly less in children taking the probiotic too, suggesting that Lactobacillus Acidophilus DDS1 combined with Bifidobacterium UABLa-12 strain at 5 billion CFU/day, may help manage ARI.
