WE have all the proof we need, we are customers of $IFUS. I buy my IFUS Intact Digest online from the top ranked world retailer of health and nutritional supplements. They have been an IFUS distributor since 2012, The first online one and there are close to 20 now.
I just bought 3 more bottles 3 weeks ago and my co-worker who is 300 lbs over weight had a high blood pressure problem. 6 drops a day in glass of water or juice and his blood pressure dropped to 121/80 in under 3 weeks. MY older sister had similar results as did I. My Blood Pressure is down from 165/111 high to 111/59 recently thanks to IFUS Intact Digest.
I set up and know the largest Canadian distributor of IFUS Blue line products. His while family uses the product. It has been a life saver for many of us, solving many digestion related ailments.
