About eight years ago, my sister and husband noticed a slight head tremor, especially when I bent my head to read my mobile phone. My doctor did a couple of checks then said there was nothing he could do for it. So I went to my naturopath and after some months of magnesium and vitamin B the tremor slowly decreased then stopped. It came back a few years ago and I consulted a different naturopath who put me onto NADH which is a Co-Enzyme, antioxidant form of vitamin B3. The tremor stopped after several months taking one tablet a day. I use ENADA, NADH from iherb. I stopped it several months ago and the tremor started coming back so I started it and it stopped straight away. I will be on it for life. It's wonderful to have found a natural supplement that has stopped tremors when the doctor said there was nothing he could do so I wanted to share this and hope it helps someone else the same way it helped me.
