Positive experiences
“I have noticed a huge improvement with those for symptoms and conditions similar to yours.”
“started at 250 mg per day. Within two weeks 90 percent of my joint and back pain was gone and I had much better range of motion, better sleep, better energy.”
“I have since up the dose to 1000mg/day and changed from capsules to sublingual delivery. The difference is night and day for the better. I have better stamina, better mood”
“Now I automatically wake up after 6.5h-7h of sleep, a massive difference. It works reliably for 4 months now”
“nicotinamide riboside (its an NAD+ booster)...it greatly increased my energy”
“I have been taking NR (Niagen) for almost 4 years and believe I have seen a number of anecdotal benefits.”
Negative and mixed experiences
“I'm 26, and I've noticed absolutely NOTHING from taking NR and NMN for the year.”
“two things that helped with my gray hair ... has been pterostilbene and nicotinamide riboside ... it felt like a waste of money for me”
“renue life nicotinamide riboside, now i dont think it works, and too expensive”
“I used Niagen 300mg, didn't notice anything...liposomal NR from Renue by Science...proved more effective at 600 mg per day than tru niagen NR at 900 mg”
“I've taken NR five days a week for the last few months, and I can say without a doubt that it's the most effective supplement I've ever taken.”
