“How old are you, like really?”

My exhausted friend was sluggin’ coffee for her brainfog like it was about to go extinct as I sat bright-eyed, rested, and ready to roll into my day.

“Seriously,” I replied to her disbelief, “I’m the same age as you.”

Our dances around the sun are growing in number, she and I are getting older—there is no denying that—but how do we feel biologically?

Do you feel your chronological age or much, much younger?

My friend is feeling her middle-of-life-ish-ness through and through. Low energy levels, low libido, and more and more issues with aches and pains are causing her to moan and groan more. And she feels like she’s looking older too with what I think is beautiful gray hair (yet, I get it).

Lately, my bio-age is younger than ever due to a cellular boost that has me vibing with a James Brown-esque, “I feel good,” all the live long day—thanks to three little letters with a big impact: NMN.

What is NAD and Nicotinamide Mononucleotide (NMN)?

Our bodies are a wonderland of intricate systems delivering what we need to where it needs to go. When our cellular miracle workers in any system break down (or full-on start to die), the others step up and in to take on more for our bodies to keep moving and a-grooving.

NAD is one of those. It is inside our cells and crucial to everything, from overall health to healing to helping our metabolism.

Here’s the thing, though—NAD levels are high and vibrant when we are young, keeping our cells nice n’ healthy. However, those naturally decline as we age. It’s a steep drop too.

By the time we hit our 50s, our NAD levels are half what they once were.

Good ol’ science has linked this drastic decline with age-related diseases from metabolic disorders and heart disease to neurodegeneration and plain ol’ accelerated aging itself. Eep.

Lucky for us, the data also shows increases to NAD levels in blood, tissue, and the body at large.

Yet, there’s a catch.

NAD doesn’t just get sucked into our cells. Precursors are needed—and NMN is especially effective to deliver the goods.

NAD = Life. It’s the energy source inside our cells. Without it, we’d die in seconds. NMN = the source for NAD.

To unpack what that means, let’s turn to an expert (of which I am not).

Longevity isn’t Magic—it’s Science.

Dr. Andrew Salzman is a prominent Harvard MD, professor, and scientist with over 30 years of expertise in NAD and cellular health. He’s the wise man behind the patented, high-potency formula for Nicotinamide Mononucleotide (NMN) I’ve been taking for over a month now. It’s an oral supplement scientifically proven from decades of research in longevity science to help our biological age.

The supplement’s name actually describes my vibe: Wonderfeel Youngr™ NMN.

Dr. Salzman’s formulation is rapidly absorbed and converted to NAD in the body. This kind of supplementation has been scientifically shown to increase NAD biosynthesis, and the list of benefits is phenomenally lengthy.

Besides boosting metabolism, improving cognitive function, and increasing libido, the effects of NMN reverse age-related decline.

I was especially interested to learn that boosting NAD levels may offer a positively promising approach to mitigating some of the adverse effects of menopause and improving well-being in aging women as well.

Diving into NMN Supplements: Wonderfeel Youngr™ NMN is seriously rooted in cutting-edge research. 

The advanced NMN supplement brings together key non-GMO and vegan-friendly ingredients that work synergistically to optimize NAD levels by delivering 900mg of NMN alongside a unique blend of powerful antioxidants—including ergothioneine from mushrooms, hydroxytyrosol from olives, and resveratrol from grapes—plus 100% of your daily Vitamin D3.

Effects of Wonderfeel Youngr’s NMN:

>> Ergothioneine: Protects cells and combats oxidative stress that can indirectly support better bone maintenance and reduce the risk of fractures.

>> Resveratrol: Supports brain health, heart function, and longevity at a cellular level.

>> Hydroxytyrosol: Helps regulate inflammation and supports metabolic and cardiovascular health.

>> Vitamin D3: Essential for the body, including its role in generating stem cells in the gut, a key foundation for overall health.

Wonderfeel Youngr™ NMN makes it easy to reap their rewards with just two capsules a day.

Does NMN Give You Energy?

After a few months of test driving Wonderfeel Youngr’s NMN, my answer is a resounding, “Yes!”

At first, I took capsules in the morning with breakfast and loved the energy bump. Since then, lunchtime was suggested for an all-day boost—and I must say I am digging that too.

Buh-bye, four-o’clock slump!

Here are 3 more Specific Ways NMN can Improve your Life.

1. Hormonal Balance from steady cellular energy—when NAD falls, your cells feel it first.
2. Healthier hair and skin.
3. Better sleep.

Other folks who’ve tried NMN are feelin’ the Wonderfeels ever too:

“I have more flexibility in my hands, and feeling my energy increase after just two weeks. It’s amazing how much more active I can be…makes me happy” ~ Lizzie

“I originally started taking this to see if it would help with my runner’s knee. …it’s helping me run longer distances, and my kneecaps don’t ache for days afterward.” ~ Carmen

“In nine weeks, my memory recall and thought processing are much more acute, especially after a few drinks the previous evening. Overall, I feel like my body is running smoother with less fatigue.” ~ Winston

“It has helped my weight stabilize. My husband has more energy and feels better overall. Hair and skin definitely improved for both of us.” ~ 5 Star Reviewer

“Six months of using Wonderfeel. My graying hair has returned to being its original brown, no gray visible.” ~ Very Happy Customer

It can’t be conclusively said that Wonderfeel Youngr prevents or reverses grey hair or other claims folks like me feel—the proper research just isn’t there yet. What can be said is that NMN supplementation works wonders for slowing down visible signs of aging, and that includes thinning strands.

My experience so far has proven several of those testimonials to be true.

My fingernails are stronger than ever. The dreaded words “dry winter skin” don’t apply to me this year. My sleep is sound.  I’ll even give the claims for the weight management a hat tip as we’re having a “Midwestern” kind-of-healthy and happy holidays and I’m steady.

Between the anecdotal evidence and the handful of studies to date, there is reason to believe NMN can improve symptoms of aging and boost (more like reduce) our biological ages, and I believe it.

It’s not just about feeling or even looking better—it’s about giving your cells what they need to work better.

But why would I need a supplement when I could eat NMN instead?

The answer was quick and concise after one web search.

Healthy foods like edamame, avocados, broccoli, and mushrooms do contain NMN, for sure, yet they simply don’t supply enough to match the amounts that show health benefits in research. In addition, heat or prolonged storage reduces NMN levels in foods.

The clinical trial and research of Dr. Salzman and his team shows stronger doses are critical to reaping all the benefits of NMN.

In fact, one of the most comprehensive human clinical trials about it to date supports 900 mg of NMN as the most effective NMN dose—which is exactly what’s packed in the two capsules of Wonderfeel Youngr™ NMN. Ta-da!

And for NMN supplements, oral capsules are the most efficient format and are widely used in all research institutes, which is a relief because injections and IVs are known to be crazy expensive and painful, while not necessarily reaching the inside of our cells, as opposed to oral administration.

The real test? Give Wonderfeel Youngr NMN a test drive yourself.
