So, I just bought 3 bottles of Life Extension NR, this is my first time trying this.
According to the studies, it seems 300 mg/day would be enough to raise blood levels of NAD to an extent. But I read somewhere that if you take less than a certain amount (1000 mg?) it only gets to the liver and not other tissues. That you would have to overwhelm the liver to get a more widespread effect.
Where did I hear/read this? Is it correct?
How much do you people take?
