I have ME-CFS and read this helped in a Swedish study.
It made a big difference for about a month. Still I won’t go off it and Chance going further downhill. I trust NOW brand.
not worth it
nothing negative about Allstar-- just, i find no use for this product

After doctor prescribed Rx's for my depression which made me even more unstable, a nutritionist recommended NADH. Once it built up in my system, it stabilized my highs & lows. I've been using it regularly for 20 years. I've had to increase it 2-1/2 mg every 5 years which is a lot better then having doctors switch you from Rx to Rx because you built up tolerance to it. NOW brand is one of the brands I trust because not all brands are the same.
I did not notice any affects from this product so it was a waste of money for me.
