I have not been officially diagnosed with TMAU, but since the age of 18, I have had a problem with underarm and private parts odor. I started using grapefruit seed extract. I take the pills and use the concentrate and zinc margarite under my arms. I have found this works great for me. Now, I can stop putting tape on the underarm part of my clothing. This was a way of preventing the odor from getting on the clothing and I would be less offensive. Just wanted to put this out there as a possible solutiion for all who suffer as I know what it is like to practice very good hygene and still smell.
