For some people, when they first start taking our products, they may experience symptoms like stomach aches or loose bowels. The reason for this reaction is that the supplements are removing various levels of bio-films from the intestinal tract, which might have built up over the years. These symptoms shouldn't last very long. But if need be, you can lower the dosages of each product and slowly increase the amount over time. But if you continue to have these symptoms, please stop taking the products and schedule a health check up with your GP or Naturopathic Doctor.
