Bio Cultures Complex — 75 Billion CFU, 25 Strains, with Prebiotics

Your gut microbiome contains approximately 100 trillion microorganisms and produces around 95% of your body's serotonin. It regulates immune function, metabolic health, inflammation and — through the gut-brain axis — your cognitive function and mood. Maintaining microbiome diversity is one of the most evidence-backed approaches to broad systemic health available.

Most probiotic supplements fall short in two key areas: the number of strains and the addition of prebiotics. Single-strain or low-strain products can temporarily boost one bacterial species without addressing microbiome diversity. Our Bio Cultures Complex delivers 75 billion CFU across 25 diverse strains, with FOS (fructooligosaccharides) and inulin prebiotics to nourish and sustain the bacteria being introduced.

Why 25 Strains and Why Prebiotics

The gut microbiome is an ecosystem. Introducing a diverse range of bacterial strains better replicates the complexity of a healthy gut than single-strain supplementation. FOS and inulin act as food for beneficial bacteria — without prebiotics, introduced probiotic strains may not survive long enough to establish.

The Gut-NAD+ Connection

The gut microbiome plays a direct role in NAD+ metabolism — certain gut bacteria produce NAD+ precursors including NMN itself. A healthy, diverse microbiome supports the body's own NAD+ production pathways. Combining Bio Cultures Complex with NMN Plus addresses both direct NAD+ supplementation and the gut-based NAD+ production pathway simultaneously.
