Evaluation of a Probiotic Supplementation in the Immune Response of Participants With COVID-19 (Coronavirus Disease). (PROVID)
Randomized, Double-blind, Placebo-controlled Study to Evaluate the Effect of the Lactobacillus Probiotic Strain in the Immune Response in Participants Positive for SARS-CoV-2 (Severe Acute Respiratory Syndrome-Coronavirus-2) Infection.
An interventional, randomized, double-blind, placebo-controlled study will be conducted to investigate the effect of a probiotic strain on the immune response in participants positive for SARS-CoV-2 infection.
The study duration will be 28 days, which includes 4 weeks product administration. Participants will be randomized assigned to one of the two study groups: the control group with placebo consumption and a probiotic consumption group.
