Gosh, he is about the most uninspired advocate for NR I've ever heard. If he were selling dollar bills for fifty cents, I'm not sure I'd be a taker. You'd think after all this time, he'd be able to come up with some, nay...any positive study results beyond... "It raises NAD levels" and some people say it gives them more 'energy'. Oh well.
There was another positive result!
The New York Magazine, April 3, 2017:
"There are no clinical data yet that Basis does anything useful in humans, so, when I visited Guarente in his office at M.I.T., I asked if he’d noticed any effects from taking it. “I have,” he said. He glanced at Elysium’s P.R. person. “Can I say it? It is O.K.?” She gave a calibrated nod, and he said, “My fingernails grow faster.” And what does that mean? “I don’t know. But something.”
First, the writer was wrong since Elysium had completed its 250 mg and 500 mg study last August and Guarente knows the resuls. For some reason Elysium's P.R. person was with Guarente who felt needed her permission to speak despite being a co-founder of the company.
Couldn't the interviewers have thought to ask Guarente what the differences were in outcomes between 250 mg and 500 mg?
There may be two not-so-great scenarios for Chromdex and Elysium. NR might only show very good results at 1,000 mg which at current prices would cost $3.50 a day, or there may be very good results as low as 100 mg which would add many more buyers but maybe not enough to offset profit loss that 250 mg brings in. We've never been told why Charles Brenner takes 250 mg of NR a day or why Elysium markets at that dose.
