To deliver the full profile of Nature?s bounty to you each nutrient in Zinc Food Complex is cultured in live probiotics. Those are the healthy bacteria found naturally in fermented foods such as yogurt tempeh kefir and sauerkraut. By culturing vitamins and minerals in a probiotic matrix of fermented organic soy fruits and vegetables we create whole-food complexes that the body can easily recognize and digest because they?re food.
