How aging actually works
Doctor Recommended. NAD+ is the one molecule your metabolic age depends on. Replace what your body stops making, and your cells stop aging faster than your calendar. — Dr. Yadegar, MD
As featured in
Two ages. One you can change.
Metabolic age is what your cells do, not what your birthday says. The molecule that drives cellular metabolism starts running out — and your metabolic age pulls ahead.
−50%
NAD+ falls by half by age 40.1 It’s the molecule that powers cellular metabolism. When NAD+ drops, your mitochondria slow — and your metabolic age climbs.
30%
drop in mitochondrial efficiency between 35 and 55.2 Same fuel demand, less output. Your cells age faster than your calendar.

“Skin holds water again. Energy lasts past 3pm. Six weeks in and the pants fit different.” — Janet L.
Most women feel a shift in energy and sleep in the first 2 weeks. Skin and hormone changes show up around week 4 to 6. The 90-day mark is when cellular renewal compounds. 84% of our customers say they feel like themselves again by month 3. Take 3 capsules with breakfast. Consistency is the active ingredient.
You have 30 days to try the full system. If it doesn't work, email hello@happyaging.com and we refund you. No surveys, no return shipment required. We'd rather you keep what's open and have your money back.
Most NAD+ products are NMN or NR alone. This one combines an NAD+ booster with 5 other systems women over 35 need: hormone support (Maca, Vitex), brain support (Lion’s Mane, L-Theanine), skin support (Hyaluronic Acid, Vitamin C), antioxidant defense (10 organic superfruits), and bloat relief. One protocol instead of 6 bottles.
No. There is no semaglutide, no stimulants, no caffeine. It is a daily nutritional protocol. Women report easier weight management because cortisol stabilizes, sleep improves, and inflammation drops. This is not a diet pill.
Yes. The formula targets two of the biggest perimenopause pain points. Probiotics, ginger, and dandelion address gut inflammation and water retention. Maca, Vitex, and pumpkin seed support hormone balance, which is the real driver of midlife weight changes. Most women see less puffiness in the first 30 days; the scale tends to move after week 6.

Discovering NAD+ as I entered into my 30s has been a game changer in how my outer appearance has improved and I’ve internally seen a shift in my energy. This supplement works well with my lifestyle and is obviously more affordable and less time consuming than taking a NAD+ drip. A must try!

I absolutely love this longevity formula. It gives me clarity in thinking, balances my hormones and I feel energized throughout the day. One of my favorites — not only the NAD+ for longevity, but all the other ingredients for glowing skin and hormonal balance I really need.

I'm a happy woman since I started taking NAD+ products because my life has changed incredibly. So, Happy Aging, thank you, thank you, thank you for these amazing products. Love you guys!

I've been a fan of the NAD+ Longevity Shots for a while, so when I added the Women's Longevity Formula to my routine I had high expectations. Honestly, it's become my new obsession.

Was taking a multi, a B-complex, a separate skin supplement, and a sleep thing. This replaced all of them and works better. Cheaper too if you do the math. Two months in, brain fog gone, mood is back to normal.

Annual physical last week and my doc asked what I changed. Inflammation markers down. Vitamin D up. I'd literally just been taking these for two months. didn't realize they were doing anything til she pointed at the labs.

Tru Niagen, Elysium, the Whole Foods one, AG1. None did anything I could feel. This one is different. I think it's the hormone stuff in there with the NAD. Idk. I just feel like myself again. 3 months in.

I stopped buying serums. My hands stopped looking like my mom's. Cheekbones came back. Six weeks. I didn't change anything else. Two of my friends are on it now.

Sounds dumb but I'd been reading the same chapter for a week. Couldn't hold the thread. Two months on this and I just blew through three novels. it's the small stuff that gets you.

started this for energy. Same diet, same workouts (which is to say, very inconsistent). The belly weight that arrived at 42 finally moved. Pants fit. tbh I don't care why it works.

Built By Experts
Women describe the same pattern to me: tired, foggy, slower recovery, harder to keep weight off. The cause is metabolic, not chronological. NAD+ drops, mitochondria slow, and the cellular machinery runs below capacity. Replace what the body stops making — and that gap closes. This is the protocol I built around that mechanism.
