Thank you for supplying feedback on the Progurt probiotic sachets. The Progurt probiotic sachets are a high potency product. If they do not produce a response after consuming 1 or 2 sachets then it is an indication that our inner terrain is not properly balanced and consequently not conducive to healthy bacterial colonisation. There are many factors that affect this including pH, mineral content, temperature, nutrient flow etc. Because of theses issues Progurt have developed the ancillary products to help address imbalances and aid bacterial colonisation. We therefore recommend that if no response is felt after consuming 1 or 2 sachets that consideration should be focused on a protocol to improve the inner terrain. When the terrain is properly balanced then we will see a very positive response to the use of the probiotics. We are always happy to discuss with clients, or those contemplating purchase, how they can get the maximum benefit from the products.
