Bests & Worsts Reviews from Amazon

I'm a physician and I originally researched Niagen because my dad started taking it and I wanted to talk him out of it (since most supplements have no proven benefit). However, after looking at the research on Nicotinomide Riboside, I realized I should start taking it too because the data available is pretty incredible and it's also proven safe. After 6 weeks, I noticed my solar lentigo (those brown spots we get from the sun/age) completely faded. This fading of sun damage makes sense since NR has been shown to reduce non-melanomatous skin cancers by about 25%. I also feels like it gives me more energy like shot of espresso without the buzz. I'm looking forward to larger human studies getting published! Hope they back up current data
