Prescript-Assist Pro™ is a broad-spectrum probiotic with 30 plus soil based, pH-resistant micro flora. We have changed the capsule to a vegetarian source so the product is now Vegan. SBO’s are soil-based probiotic organisms found in healthy soils which produce and release powerful enzymes that prepare and purify soil to support plant growth. Natural soil is a living biomass composed of SBO’s, fungi, yeasts, and microscopic insects. The role of SBO’s is to keep the soil biomass in a healthy dynamic balance that supports the growth of plants and animals. Additionally, SBO’s simultaneously produce and release specific nutrients necessary to accelerate plant development and reproduction. SBO’s play the same role in the gut as they do in the soil: supporting the healthy growth of organisms.
