What are Toxaprevent MEDI PLUS Sachets? Toxaprevent MEDI PLUS Sachets are used to absorb and remove toxic substances from the upper digestive tract (mouth, oesophagus and stomach) using the active ingredient MANC® (Modified and Activated Natural Clinoptilolite). The sachets regenerate the intestinal mucosa and supports intestinal health by removing environmental pollutants and irritants. Targeting the Upper GI the MANC® absorbs and removes toxins which are linked and attribute to specific common conditions such as reflux disease. Once these toxins have been absorbed they are safely passed out via natural bowel movement. MANC® is a clean form of zeolite which is patented for its ability to absorb Heavy Metals (Lead and Mercury), Histamine and Ammonium.
