Glutathione is a heavy metal detoxifier made by the human body, but often our bodies can't make enough of it to keep up with moving toxins out of the body. Glutathione can also be administered intravenously by some doctors. Doctors who are knowledgeable with DAN (Defeat Autism Now) protocols should be familiar with intravenous glutathione and heavy metal detoxification in general. Intravenous glutathione has helped my daughter who had been diagnosed with high functioning autism when she was little. It's also helped me greatly when I had a local anesthetic applied for a minor surgery. After the surgery, my body went numb all over and I felt tired and lacking in energy. I think my body couldn't remove the anesthetic, because, like my daughter, I was low in glutathione. After I had intravenous glutathione about a week later, I felt great.
