There suggestions they may specifically enhance activities digestive enzymes nutrient absorption. Experimental comparisons with antibiotics organic acids suggested similar on gut. include reduced bacterial colony counts, fewer fermentation products, greater digestion probably reflecting an overall gut equilibrium.
