A number of experts weigh in on how long it takes NAD boosting vitamin supplement Nicotinamide Riboside “NR” (FAQs) (Reviews) to impact you:

Chromadex CEO Rob Fried on the Optimal Performance Podcast:

“I’ve been taking it (TRU Niagen) for 5 years and I’ll say that I started noticing fairly dramatic things after 3 months.

Chromadex CEO Rob Fried on a Recent UK Radio Appearance:

“Most people do feel it within a couple of weeks BUT many do not.

I mean “feeling” is a tough word. It’s not coffee. It’s not a stimulant. It’s not sugar. It’s not a hormonal thing. So, there a lot of things that affect your feeling.

We recommend that people take it over at least a couple of months and they’re in touch with their bodies and their physiological performance, their workout levels, sleep routines, and their general energy levels — with a great level of consistency people notice a difference in that timeframe.”

Former NFL Star Shannon Sharpe on the Adam Carolla Show:

“So I started taking this product called TRU Niagen. I took for about 8 weeks and I noticed that…ok, I do have some energy. I do have the energy to go do that 4pm workout and not start yawning halfway through the workout.”

“So I’ve been taking that for about a year and a half now and it’s a made a huge difference for me.

Dr Charles Brenner on the BulletProof Radio Podcast:

“For people that know their mile time or their swim time or they have something of a health complaint like, gee, I wish I could sleep a little bit better or I wish that I could focus a little bit better in the afternoon and they keep a journal, when they try Nicotinamide Riboside (NR)…

“….probably by the second or third week — and some people notice something on the first day.

“But most of us notice something in this second or third week that they’re just functioning at a sort of higher level. That’s something that you can sort of notice if you keep a journal.

Chromadex CEO Rob Fried on the Optimal Performance Podcast:

“We see that if people take it over a few weeks their levels plateau after about 2 weeks. Their NAD levels plateau after about 2 weeks. But you need to keep taking it to maintain that level.

If you take it for a few months and then you stop taking it the NAD levels will gradually decline but slowly and not all the way back to the beginning. So there’s clearly some sort of restorative, therapeutic benefit in the engine of manufacturing NAD.”

“But I think it’s mostly because it takes that long for people to realize that it’s impacting them. I think it’s so subtle that it takes an amount of time for people to understand…..Sometimes it takes a few months for people to realize that they’re living differently. They’re outlook is a little bit different. They’re ambition level is a little bit different. They’re doing things that they sort of quietly stopped doing — and now they feel like doing again. So, that’s why we say 2-3 months.”

“But there are people that notice it dramatically after just a few weeks. Most people though are not so tuned in and they’re mostly looking for how they feel. And of course feeling is more impacted by transitive things like hormones or stimulants that might be in your food or coffee. That has a greater impact on your actual feeling in the short term. That’s why we say 3 months.”

Dr Charles Brenner on the PrecisionOne Health Podcast:

“Human clinical trials that we’ve run and others have run have shown that within a number of hours oral Nicotinamide Riboside (NR) is converted into higher blood NAD and within a week the blood NAD is at a higher level, and within 2 weeks it’s at the higher plateau that is achievable at particular doses of NR safely.

“So we think that boosting NAD has a use case in basically optimizing health.

“The message coming out (from recent studies) is that it looks as though Nicotinamide Riboside (NR) can potentially improve markers of inflammation in as little as 3 weeks, can improve body composition in women in as little as 6 weeks, and start clearing fatty liver in about 12 weeks in men.
