Is it really with 300mg nicotinamide riboside ?

As to the other answer that said "Look up ChromaDex’s CERT program whereby they supply the Nicotinamide Riboside to virtually all the pre-clinical and clinical trials on NR." Even if they were supplying NR-pills, that by itself does not prove that their pills actually contain NR. Nor that they contain it to the indicated degree.

Does anyone have the nutrition label for this? Would love to see what's in a capsule!

How long do you have to take this product in order to notice a difference?

I stared at 250 mg. After about two months I noticed that I no longer had muscle inflammation causing stiffness of the muscles in the morning or after sitting too long. At age 67 that made me feel younger. Things like a reduction of LDL and triglyceride levels came months after I increased to 600 mg. My small cataracts vanished after I increased to 900 mg. A study showed it increased NAD by 22% at 100 mg, 54% at 300 mg, and 141% at 1000 mg. (I may be slightly off on these numbers, but they are approximated correct.)

Is this brand trustworthy? Is this product 3rd-party lab tested for purity?

Description

A COMPLETE ANTI AGING SUPPLEMENT - Support whole body wellness and boost cellular energy with Tru Niagen, a patented NAD+ supplement that supports the 37.2 trillion cells in your body Tru Niagen helps the production of nicotinamide adenine dinucleotide to promote healthy cell activity and can help reduce aging-related health concerns. Tru Niagen is clinically proven to be one of the safest and most efficient boosters of NAD+ levels, shown to increase NAD+ over 50% in just 2 weeks with daily use.
VITAL FOR CELLULAR ENERGY - Tru Niagen supports your ability to stay healthy by boosting NAD+ levels, which naturally decline as you age. NAD+ is vital for cells to function and repair. It supports brain health, muscle health and recovery, heart health, cellular energy and repair, and lifestyle stress management. Patented Tru Niagen is more efficient at raising NAD+ than other NAD+ precursors such as NMN, niacinamide, or niacin.
TRU STORY: WITHOUT NAD, CELLS DIE - Our bodies naturally decrease in NAD+, with up to a 65% decline between ages 30-70. Effects of metabolic stress and time on your cells can accelerate aging, which leads to many health concerns. Everyone’s body, stressors, and goals are different. Most clinical studies have used 1000mg daily. NAD+ decline begins in your 30s, it's recommended to start with 300mg daily. As you age and are exposed to more metabolic stressors, such as environmental factors or immune challenges, you can move to 1000mg daily. Always check with your healthcare provider for the best dose for you.
TESTED FOR SAFETY, POTENCY, AND PURITY - Tru Niagen is one of the most well-studied, patented, supplements. Our patented ingredient Niagen has achieved regulatory acceptance by the US FDA for use in supplements: twice as an NDI (New Dietary Ingredient), and once as GRAS (Generally Recognized As Safe). Every batch is made in the United States with globally sourced ingredients and third-party tested by ISO/IEC accredited labs for potency, safety, and purity. Tru Niagen NAD+ capsules are vegetarian, gluten free, nut free, caffeine free, and have no artificial flavors or colors.
SUPPORTED BY DECADES OF RESEARCH - Tru Niagen is one of the most well-researched patented supplements and is backed by a Nobel Prize winner, 50 owned and licensed patents, 500+ published scientific studies, 300+ global research collaborations, and 40+ clinical trials. Supported by decades of science and research, Tru Niagen is truly one-of-a-kind.

Tru Niagen Nicotinamide Riboside - 300mg per Serving 30 Capsule Review: Excellent, effective for mitochondria patients - Really wonderful product. Without NAD mitochondria cannot work, we feel fatigue discomfort... everyday life is bane. So think, how would be miserable for a mito patient to live a day. A total mess... My physican suggested to take add NAD to other supplements.... The change was wonderful. Totally satisfied with the product, confident now.... can gradually come back to normal life. Thanks to Truniagen NR. The price is so high, if moderate it, it would have helped many mito patients... as I they have to take many more costly supplements regularly to maintain their daily life. Review: NAD - ممتاز جدا للتركيز والذاكره انصح فيه حاليا اعتقد بأني كملت سنه أوصي فيه بقوه

A good quality supplement from a trustworthy source

I chose this because Im in my 60s and wanted to try a nicotinamide Riboside supplement. I trust this one. It's expensive but it's worth the money to find out if it has an effect. I started with the 300mg first thing in the morning. for a month. It feels a little like drinking an energy drink. I ordered the 1000mg to move to next. 1000 seems like the amount that all of the studies find the best results.

Feel Younger, One Capsule at a Time!

TRU NIAGEN has become a surprising addition to my wellness routine. After a couple of weeks, I noticed a subtle but real boost in energy and focus—not the jittery, coffee-fueled kind, but a steady, all-day vitality. It’s like my cells got a wake-up call to stop slacking and start repairing! The science behind Nicotinamide Riboside (NR) is pretty compelling, and I appreciate the patented formula—it feels like I’m giving my body something it actually needs. It’s also great for supporting healthy aging, which I’ll admit I’m starting to think about more these days. Cons? It’s not cheap, so if you’re expecting instant results, the price might feel steep. This is more of a long-term investment in your health than a quick fix. Also, it’s one capsule a day, which is super easy, but you do need to stay consistent to really feel the benefits. Overall, it’s a great option for anyone looking to support cellular health and stay sharp, active, and energized as they age. Worth the try if you’re serious about feeling your best! 4.6/5
