Microbiota Accessible Carbohydrates
Microbiota-accessible carbohydrates (MACs) is a scientific term encompassing all carbohydrates that resist human digestion and are fermented by gut bacteria (prebiotics). This includes inulin, FOS, GOS, resistant starch, beta-glucan, pectin, and many others. Higher MAC intake is associated with improved gut health, immune function, and metabolic health. This is a CATEGORY entry, not a single supplement. The health benefits of dietary fiber and prebiotics largely come through this mechanism. Whole plant foods are the best MAC sources; supplements can also provide specific prebiotic fibers.
⚠️ Limited Research Available — This supplement has emerging preclinical research but no graded clinical outcomes yet. Evidence is based on animal or in-vitro studies only.
