Nature’s One® organic pediatric products contain organic milk from cows that are NOT treated with antibiotics or growth hormones. Nature’s One® purchases its organic nonfat milk from farmer-owned cooperatives, which assures our cows graze in pastures that are free of pesticides. Organic pastures produce healthy cows and high quality organic milk. The Cornucopia Institute gave Nature’s One® organic milk suppliers an “excellent” or a “4 cow rating”. You can feel good knowing Nature's One® formulas and nutritional supplements do not contain artificial flavors, colors or sweeteners, genetically modified ingredients, pesticides, added growth hormones or hexane processed oils.
