The microorganisms living in the gut make up your gut microbiome. A healthy balance of microorganisms improves the immune system, digestion, and contributes to your overall health. When the gut microbiome is imbalanced, it may lead to GI disorders, weight gain, chronic inflammation and it lowers your body's ability to fight infection. Supplementing with key vitamins and minerals like magnesium, digestive enzymes, glutamine, probiotics and others, help to support the health of the microbiome.
