Omega-3 fatty acids (EPA and DHA) have a direct well-researched relationship with the gut microbiome. They increase microbial diversity, support the growth of beneficial bacteria including Bifidobacterium and Lactobacillus, reduce intestinal inflammation, and strengthen the gut barrier. Omega-3 also improves probiotic colonisation - helping beneficial bacteria establish themselves more effectively in the gut. This is why beie. formulations include omega-3 alongside probiotic strains.
