A deeper understanding of the microbiome (your entire gut ecosystem) has changed everything we thought we knew about nutrition, digestion, immunity, and metabolism. Specifically formulated to optimize this ecosystem, Ultimate Microbiome provides prebiotic, probiotic, and postbiotic support. Through an exclusive probiotic blend, our proprietary i26 Hyperimmune Egg Powder, and a powerful Multi-Enzyme Complex, it provides holistic gut health properties not found in any other product. NOTE: What exactly are postbiotics? Postbiotics are metabolic byproducts of probiotic bacteria, which seem to be responsible for many of the beneficial effects of probiotics. They may also provide protection against harmful bacteria, which is key to helping regulate your gastrointestinal health.
