Dr. Al Sears writes: “Protect yourself with probiotics. Probiotics are well-known for their ability to improve gut health. But they also offer powerful protection for your immune system, especially when preventing the flu and colds. According to a study published in the Archives of Medical Research, there is also early evidence to suggest that probiotics might help prevent Covid-19. Strains of probiotics that boost your immunity and reduce the risk of viral infections include acidophilus, Bifidobacterium, L. bulgaricus, S. thermophilus, and Bacillus subtilis.” Will these strains be safe and effective? Is one superior to the others?

All of these have a modest benefit in affecting the microflora of the gut and this will help prevent viral invasion of the intestinal mucosa. It is not a major preventative but has other benefits as well to impart a healthy microbiome, and that supports the being in other ways as well, so overall this is a useful adjunct to adopt.
