Millions of patients are benefiting from discoveries by Dr. Salzman in areas including mitochondrial health, gastrointestinal microbiota, damage caused by inflammation and oxidative stress to human cells and DNA, autoimmune disease and cancer.
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.
Ingredient Story
Backed by the latest human clinical trial with
900 mg NMN in just two capsules
A revolutionary daily solution
to improve cellular health.
Meet Wonderfeel 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™.


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.

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.

Common Questions
What are the benefits of raised NAD levels?
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. Read morehere.
When will I see the effects of NMN?
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. We’ve got a quick read if you want to knowHow Long Does it Take to Work?.
NMN vs NR as NAD precursors
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. More on this subjecthere.
What is the best form of NMN delivery, capsules, liposome, or sublingual?
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?
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.
I heard that NMN needs to be refrigerated. will it be affected by shipping or sitting in my mailbox?
I heard that NMN needs to be refrigerated. will it be affected by shipping or sitting in my mailbox?
Great question! Our NMN is stabilized, which means Youngr™ and Capsuls™ do not require refrigeration and have a shelf life of 24 months when stored at room temperature. The key is to ensure your bottle or pouch is tightly sealed away from heat, humidity and exposure to oxygen.
Our NMN has undergone extensive stability tests and is confirmed to maintain its purity at temperatures as high as 130° F for up to 10 days, so you can be assured your capsules will still be safe to consume after exposure to various temperatures during shipping.
Do you use liposomal NMN in Youngr™ or capsuls™?
Do you use liposomal NMN in Youngr™ or capsuls™?
Our NMN is not liposomal, but this is by design! Currently, there’s no concrete scientific evidence suggesting that liposomal or sublingual NMN is more bioavailable. Leading research supports NMN encapsulated in powder form as the most effective delivery method for raising NAD levels.
Liposomal NMN also faces potential stability and absorption issues, as it’s contained within hydrophilic nanobubbles prone to degradation.
We continue to research the potential through ongoing studies. Right now, the evidence is clear that NMN in powder form has the best stability, dependable bioavailability, and effectiveness in boosting NAD levels. Our article about thelargest clinical trial with NMNexplains more
Do you offer pure NMN?
Do you offer pure NMN?
Our NMN is stabilized and lab-tested with a purity rating of more than 99%. For those seeking NMN as a standalone supplement, Wonderfeel offers NMN Capsuls™.
Could youngr™ NMN interact with my current medications or supplements?
Could youngr™ NMN interact with my current medications or supplements?
It’s always best to consult your physician before starting any new supplement, including ours. This is particularly important because some of our ingredients, like resveratrol and hydroxytyrosol, are metabolized by liver enzymes, specifically CYP3a4. If your current medications also engage these enzymes, a conversation with your doctor is essential to ensure compatibility.
Does age, weight, or gender matter in NMN dosing?
Does age, weight, or gender matter in NMN dosing?
NMN is particularly beneficial for individuals aged 30 and above, aligning with the time when the body’s natural NAD production gradually begins to decline with changes you may not even notice for several years. For adults over 30, our recommended NMN dosage of 900 mg isconsidered safeand effective.
Regarding gender, there’s no current evidence to suggest that it plays a significant role in the dosing requirements for Nicotinamide Mononucleotide (NMN).
As for body weight, current human studies on NMN do not suggest the need for weight-based dosing adjustments. However, if you have concerns about NMN dosing, it is recommended that you consult with a healthcare provider who can evaluate your individual needs and provide guidance on the appropriate dosage.
What's the best time of day to take NAD Boosters?
What's the best time of day to take NAD Boosters?
For the best results, we suggest taking Wonderfeel NMN in the morning hours. Research shows that consistency and timing are key to maximum efficacy. So aim to take your NAD precursors at the same hour each day to support your body’s circadian rhythm, making any necessary adjustments based on your unique sleep patterns and lifestyle.
