Fermented soy is a centuries old preparation of soy that renders it highly nutritive and wholesome. Asian cultures have long used small amounts of fermented soy in their daily diets as a health and wellness food. Fermentation of soy ensures a safe and highly beneficial product and creates a more gentle, digestible form. Fermentation results in a nutrient-dense form of soy that is a wonderful addition to our diets. We use certified organic, non-GMO fermented soy in small amounts as a nutritious protein source in our whole-food vitamin growing process. The soy is actually digested during the process and broken down into its amino acid components so there are only small amounts of it present in our finished products. All of our products that contain soy or use soy during our vitamin-making process are labeled as such.
