Discover the benefits and science behind the revolutionary synthesis we call Youngr™.

How many milligrams are in NMN Capsuls™?

Each capsule contains 500 mg of pure nicotinamide mononucleotide. We recommend taking two capsules daily for a total of 1000 mg of NMN.

Each bottle contains 60 capsules totaling 30,000 mg of NMN.

Capsule size 0 – 21mm x 7mm.

Can I order a pouch instead of a bottle? Does the pouch cost less?

Two good questions with an interesting twist. We don’t sell pouches individually, you will need to subscribe. Your first order arrives in our elegant glass bottle that can be refilled every month.

While our refill pouches made with ECLIPSE™ technology are a win for the environment, they actually come at a higher production cost than our glass bottles, so the price doesn’t change. The reality is that eco-friendly manufacturing solutions are still catching up, requiring us to source from niche manufacturers who specialize in these greener solutions.

Is Youngr™ NMN vegan, non-GMO and gluten-free?

Yes, yes and yes! Youngr™ NMN does not contain soy, gluten, dairy, or fish, and we use non-allergenic rice hull powder for stabilization. Our capsule shells are 100% vegan and made from vegetable cellulose.

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™?

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 the largest clinical trial with NMN explains more.

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™.

Usage

How much Youngr™ NMN should I take daily?

Based on one of the largest clinical trials, we recommend taking two capsules daily, which provides you with 900 mg of NMN. See the dosing logic behind our 900 mg NMN Youngr™ formula. 

What is the suggested daily dose for Capsuls™?

For those taking Capsuls™, we recommend a daily dose of two capsules, providing a potent 1,000 mg of NMN. This dosage aligns with the findings of recent large-scale clinical trials, where NMN has shown effectiveness at doses ranging from 600 to 1200 milligrams per day and significantly less effective at lower doses. In comparison, our Wonderfeel Youngr™ NMN provides a 900mg dose alongside other beneficial ingredients.

Notably, prominent longevity researcher and Harvard professor David Sinclair takes 1,000 mg of NMN daily to achieve optimal results.

Additionally, NMN is a water-soluble molecule, meaning it can be absorbed efficiently by the body without the aid of dietary fats if taken separately.

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 is considered safe and 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.

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.

Can I open the capsules and consume the contents directly?

Absolutely! You can take our capsules in whatever format you choose. For a twist, try sprinkling it into your smoothie or mixing it into a cold beverage. You may notice a mild citrus flavor depending on your preferred use.

IMPORTANT: 
Heating isn’t recommended as it could affect the potency of the ingredients. 
Consume within a few minutes after mixing to ensure the ingredients maintain stability.

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.

Safety

NMN: Safe as it gets when it comes to supplements.

NMN has no known side effects. A human clinical toxicity study conducted at Keio University concluded that NMN can be safely administered and that it is effectively metabolized in the body. Subjects were taking 500 mg NMN per day.

Numerous studies have shown that the administration of even extremely high doses of NMN in mice revealed no toxicity or side effects. By and large, a high dose of any drug in mice will cause immediate side effects. It’s reassuring that this is not the case with NMN on mice.
Professor David Sinclair at Harvard Medical School, an expert in NMN and NAD science, states that “human studies with NAD boosters are ongoing and so far, there has been no toxicity, not even a hint of it.” 

However, we look forward to deeper research in this area.

Everything Else

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 subject.
