Bifidobacterium are one of the most important and best characterized groups of beneficial bacteria. They support overall gut health and function, help produce vitamins and beneficial hormones such as serotonin and melatonin. They also influence the body’s immune system and may offer protection against inflammatory diseases [1], [2], [3]. Keeping your Bifidobacterium in an optimal range will: - Support regular bowel movements (and aid in constipation). - Encourage healthy weight control. - Help digest complex carbohydrates (ex: potatoes, beans, rice, oats). - Lower the gut pH to prevent the growth of unfriendly microbes. - Protect against inflammatory diseases. - Support the overall immune system [4], [5], [6], [7]. It is worth noting that Bifidobacterium are very vulnerable to antibiotics and levels usually need to be replenished through food and/or supplements after infections. (Adapted from Tiny Health)
