Peak Immune 4 Supplement (Formerly MGN-3)

PeakImmune4 is an immune boosting supplement created in 1992 from Daiwa Health Development in Japan. This is the same MGN-3 supplement made in Europe, but with a new name (old company name of Daiwa Pharmaceutical Co., Ltd. It uses a patented proprietary formula, Rice Bran Arabinoxylan Compound. Unlike dietary fiber laxative products that do not enter the bloodstream, this unique fiber has been broken down so it can pass into the blood stream and reach the cells of the immune system.  What is even better, is that this same company now dropped the price of Peak Immune 4 so it’s even cheaper than BioBran! And it’s the same exact product, just a new name and lower price!


  • Strengthens Your Immune System
  • Increases Activity of NK, T & B Cells in the Body
  • Helps the Immune System Fight Off Diseases of the Immune System

I had never heard of this brand before this product, but now Daiwa is on my radar for being a pretty decent vitamin and supplement brand. This product, Peak Immune is a pretty decent immune system booster that is different than your typical immune system supplements. Usually, immune system supplements are just vitamin C and possibly some other vitamins. This however, increases the T and B cells that are already in your body to help boost your immune system.
