Human Clinical Study

The largest human clinical trial to date was conducted with 80 patients. We have partnered with the authors of the study and published insights including undisclosed data in order to help with the dosage question in 2022. This graph here displays one such crucial data by looking at the median scores.

Why Youngr™?

We have engineered our patented Youngr™ capsules with potent antioxidants toprotect NMNagainst different types of oxidative stresson its journeythrough the bodyand into the cell. Working asdouble agents, these antioxidants also act assirtuin activators, the crucial enzymes busy at work making new mitochondria. Our multi-targeted approach makes Youngr™ an unrivaled NMN supplement.

    Youngr™

    An advanced take on NMN. Built with emergent antioxidants and sirtuin activators, our patented formula was built to defend NMN on its path to your cells. When you can get more NMN where it needs to go, your body will start producing more of the NAD it needs to feel healthier, stronger, Youngr™.

    Youngr™​Enjoy the benefits of everyday use

    Recapture YourYouth Energy

    NAD is the source of life at the cellular level. The more your body makes, the better, and it’s abundant in our youth.

    Improve Focus and Clarity

    Improve Focus and Clarity

    There’s more at play here than just NMN. Ergothioneine, an active ingredient in Youngr™, is the latest focus in scientific circles for enhancing cognitive function.

    Increase Athletic Performance

    A recent clinical trial concluded that NMN increases aerobic capacity during exercise, the likely result of enhanced O2 utilization in the muscle.

    Reduce the Impactof Late Nights

    When did you last feel fresh-faced and ready to conquer the day after a long night of indulgence? Increasing NAD levels helps our bodies function better, and recover faster from whatever your lifestyle demands.

    Optimization Inside & Out

    With everyday use you’ll notice improvements in skin elasticity, but the ripple effect of rising NAD levels are also benefitting your liver, brain, and other organs, helping your body to function better and extend its youthful resilience.

      Common Questions

      What are the benefits of raised NAD levels?

      People report a variety of effects ranging from increased energy, clearer thinking, and improved skin elasticity to noticeable relief from aches and pain, improved sleep, along with rapid recovery from hangovers and jet lag.

      When will I see the effects of NMN?

      We have people reporting increased energy and improved mental clarity within the first one to three weeks, while others find it takes a month or two. For more profound effects to manifest, it may take six months. The slow and steady decline of NAD begins around age 30, and the build-up is no different, so give it time. A lot depends on what age you start, if you’re under 40 and fit, you’ll have to pay close attention. Over 40s caught off guard by the signs of aging may notice that youthful feel around the 4-month mark.

      NMN vs NR as NAD precursors

      NMN is an intermediate compound between NR and NAD, meaning NR converts to NMN, at which point NMN triggers NAD production. By taking NMN directly, you eliminate the step of having your body convert NR to NMN.

      What is the best form of NMN delivery, capsules, liposome, or sublingual?

      We are investigating delivering NMN in various formats in order to increase its bioavailability. Currently, there is no scientific evidence to support that NMN in sublingual or liposome forms having higher bioavailability. Furthermore, no leading research institute is using NMN in such forms as in liposomes and sublinguals to boost NAD levels. Currently, oral capsules are the most efficient format and are widely used in all research institutes. We certainly look forward to sharing the findings of our research led by Dr. Salzman, an NAD expert.

      What's the recommended dose?

      The recommended daily dosage is two capsules taken in the morning. Two Wonderfeel capsules contain a total of 900 mg NMN + sirtuin activators.
