Product details For optimal gut health, you need two different types of beneficial bacteria: conditioning probiotic spores, or Soil-Based Organisms (SBOs), and reseeding probiotics. Conditioning probiotic spores, like a gardener, act as the foundation of your gut, pulling weeds, detoxifying the soil, and replenishing its energy nutrient content. They provide a healthy foundation and grow-tedium for the growth of good bacteria. Reseeding probiotics, on the other hand, provide the new seeds to replace the good plants in your garden that wither due to a lack of proper nutrients or assaults like harsh chemicals and herbicides. Just as you need to motor your garden to thrive, so does your gut. Soil-based organisms (SBOs) are bacteria spores that work in your gut much like a gardener. They provide key conditioning strains of bacteria that help protect your gut flora, condition it, and prepare it for the introduction of probiotics.
