For women who used to be the sharpest in the room
Doctor Recommended. The word-finding difficulty, the slower recall — these are neurological, not psychological. NAD+ is the fuel neurons need most. — Dr. Yadegar, MD

What your doctor probably hasn't told you
When estrogen starts to shift in perimenopause, NAD+ in your neurons drops with it. That's not stress. That's biology. And it explains exactly what you've been feeling.
−50%
NAD+ levels drop by half by age 40.1 Neurons depend on it for energy production, myelin maintenance, and synaptic signaling. Less NAD+, slower processing, harder word retrieval.
#1
Word-finding difficulty is the first cognitive complaint women report in the perimenopausal transition — before hot flashes, before sleep disruption.2 Most are told it's anxiety or burnout.

We surveyed 800+ women taking NAD+ Advanced daily. Here's what they reported after 3 months on the protocol.
Mental Clarity
84%
feel sharper focus and lifted brain fog by week 4. Verbal recall comes back before the afternoon crash does.
Deep Sleep
92%
report deeper, uninterrupted sleep within the first 30 days. Consolidated sleep is the brain's recovery window.
Steady Mood
71%
say mood, focus, and mental stamina were steadier week to week. Less snap. More of the version of themselves they recognize.
Sustained Energy
78%
say energy held steady through the day. The 3pm wall that made afternoon meetings feel impossible is gone.
*Post-purchase survey of 800+ customers taking NAD+ Advanced daily, 3+ months in.
Why this one, not the others
Every other cognitive supplement was formulated on male physiology or gender-neutral benchmarks. This one addresses the specific cellular shifts that drive cognitive change in women.
Four NAD+ precursors — NMN, NR, NAD, and Trans-Resveratrol — in one liposomal blend. The format your neurons can actually absorb.
Brain Booster Blend
84%
of women reported sharper mental clarity by week 4. Lion's Mane, L-Theanine, and Ginkgo biloba — the cognitive layer every generic NAD+ supplement leaves out.
Hormone Harmony Blend
71%
say mood, focus, and mental stamina stabilized week to week. Maca, Vitex, and pumpkin seed address the hormonal root of perimenopausal cognitive change.
Created by Dr. Daniel Yadegar, a Harvard-trained physician specializing in cellular aging. Third-party tested for purity and potency. Every batch.

“I couldn’t hold a thought through a meeting. Two months in, my team actually commented that I seemed sharper. I didn’t tell them what changed.” — Sarah H.
Most women feel a shift in mental clarity and energy in the first two weeks. Word-finding and verbal recall tend to improve around week 4 to 6, as NAD+ levels build in neuronal tissue. The 90-day mark is when the full cellular effect compounds. Consistency is the active ingredient — three capsules with breakfast, every day.
The Brain Booster Blend — Lion's Mane (10:1 extract), L-Theanine, and Ginkgo biloba — is formulated to support verbal fluency and working memory. The NAD+ Super Booster Blend addresses the underlying cellular energy deficit in neurons. We can't make disease claims, but 84% of our customers report sharper focus and lifted brain fog by week 4. Most were dealing with exactly what you're describing.
Those products were formulated for general cognitive performance — most of them on male physiology. None of them address the hormonal root of perimenopausal cognitive change. Happy Aging includes a Hormone Harmony Blend (Maca, Vitex, pumpkin seed) alongside the brain support, because the cognitive symptoms you're experiencing are downstream of an estrogen and NAD+ shift, not just a focus deficit. Treating the signal, not just the symptom.
Yes. It's the NAD+ Women's Longevity Formula — the same product used across the perimenopause and GLP-1 protocols. The formula doesn't change. What changes is which benefits you'll feel most, depending on where you are in your perimenopausal transition. Women whose primary complaint is cognitive tend to notice the Brain Booster and NAD+ blends first.
You have 30 days to try the full system. If it doesn't work, email hello@happyaging.com and we refund you in full. No surveys, no return shipment required. We'd rather you keep what's open and have your money back.

What you'll notice, week by week
01
Week 1–2
You sleep through more of the night. That matters because deep sleep is when the brain clears metabolic waste and consolidates memory. You'll notice the difference before you have words for it.
02
Week 3–4
Brain fog eases. Word retrieval gets faster. The three-second pause before the right word arrives starts getting shorter. Focus holds longer in meetings.
03
Week 5–8
Verbal fluency is back. The mental stamina that used to carry you through long days returns. Your thinking feels less like wading and more like moving.
04
Week 12+
Three months in. People in your life notice before you do. You don't have one answer for what changed. The answer is cellular.

I'm not exaggerating. I had googled it three times. The word-finding thing was scaring me. Six weeks on this and I genuinely stopped worrying. Not because I told myself to. Because it wasn't happening anymore.

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.

I couldn't hold a thought through a meeting. Two months in, my team actually commented that I seemed sharper. I didn't tell them what changed. Some things stay private.

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.

Was taking a multi, a B-complex, collagen powder, 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.

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.

First two weeks it was sleep — deeper than I'd had in years. Then around week four the mental fog started clearing. I hadn't realized how much the bad sleep was affecting my thinking. It's all connected.

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.

I knew exactly what I wanted to say. There was just this 3-second gap where the word wouldn't come. Client meetings were becoming a source of anxiety. That gap is gone now. It's the single thing that made me renew for 6 months.

Discovering NAD+ as I entered into my 30's, 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 than taking a NAD+ drip. A must try!

Word-finding difficulty, slower verbal recall, the 3pm mental wall — these are neurological, not psychological. When estrogen shifts, NAD+ in neurons drops with it. That depletes the mitochondrial energy neurons need for fast synaptic signaling. The Brain Booster Blend directly addresses that gap. The Hormone Harmony Blend addresses the upstream cause. Together, they do what no generic nootropic does: treat the biology, not just the symptom.

The word-finding difficulty, the slower mornings. It's cellular. Not permanent.
Perimenopause is a shift in how your neurons are fueled. Shifts can be addressed. The next six months are the window.
