Overview
Athletic Greens AG1 is marketed as a comprehensive, once-daily nutritional beverage that replaces multivitamins, probiotics, digestive enzymes, and adaptogenic blends. In this clinical audit, we review the scientific backing behind its key components to determine if it provides measurable gastrointestinal benefits.
Probiotic Viability
AG1 contains 7.2 billion CFU of dairy-free probiotics, specifically Lactobacillus acidophilus and Bifidobacterium bifidum. These strains survive stomach acidity to populate the gut lining, promoting an acidic environment that inhibits opportunistic pathogens and supports mucosal immunity. Refrigeration after opening is required to maintain strain viability.
Enzyme Matrix & Bloating
The addition of bromelain and papain provides enzymatic support for digesting complex proteins, preventing colonic fermentation which is the primary cause of bloating. Our test subjects reported a significant reduction in stomach tightness and flatulence within the first week of daily morning consumption.
Clinical Spotlight: NSF Certified for Sport
AG1 is third-party tested and Certified for Sport by the NSF. This means it is free from 280+ banned substances, heavy metals (such as lead and arsenic), and pesticide residues, ensuring the highest standards of safety and purity.
