A 90-second read on what each formula contains, who it’s built for, and which one fits your daily.
01 Why this comparison
Most longevity supplements weren’t built for women. IM8 is one of the better ones in that category. Polished formula, transparent COA per batch, NSF Certified for Sport, ninety-plus ingredients in a single drink. A good fit for a lot of buyers.
A poor fit for women.
Tired, foggy, holding weight that won’t move. The diet that worked at 35 stops working. The body running on different hormones isn’t a smaller version of the body that ran on more, it’s a different body. Estrogen falls, cortisol rises, NAD+ collapses by half. Skin and brain feel it first.
Happy Aging is the answer to that conversation. A targeted protocol of thirty actives, six blends, three capsules, designed around female biology and the twelve hallmarks of aging that show up first in women.
Below, side by side: where IM8 looks impressive on paper, and where Happy Aging delivers on what women came in asking for.
Happy Aging’s 3-month bundle. The format twelve thousand women already use daily.

“The capsule format is the unsung win. I never built the morning shake habit with the powder brands. Three caps with breakfast, I keep up.”
★★★★★
“I take both. IM8 in the morning for the broad coverage, Happy Aging at breakfast for what IM8 doesn’t address. Honest answer if you’re comparing.”

03 Two philosophies
IM8 fits ~75 ingredients into one scoop. The thinking goes: replace the multivitamin, the greens, the probiotic, the joint formula, the electrolyte mix, the recovery drink. One scoop, every base covered.
A marketing answer disguised as a formulation answer. The more lines you fit on a label, the lower the dose of any single active, and the more generic the formula has to be to satisfy "everyone." That trade-off shows up on the supplement facts panel.
Happy Aging takes the opposite approach. Three capsules, thirty actives, six named blends. Each one chosen for what changes in a woman’s body specifically, not for what looks comprehensive on a marketing diagram.
A focused formula at meaningful doses outperforms a 75-line "kitchen sink" at hidden doses. Especially when the buyer has specific needs the kitchen sink wasn’t designed around.
Read IM8’s product page from top to bottom. The words estrogen, perimenopause, menopause, and female never appear. Not as a critique. As a description of what they were building.
04 Female foundation
The buyer
“I wasn’t looking for a longevity supplement. I was looking for the thing that would help me feel like myself again.”
The conversation that built the formula.
Most foundational supplements skip this part. The body running on different hormones is a different body, not a smaller version of the one that ran on more. Different demands. Different deficiencies. Different downstream effects on energy, weight, skin, mood, and sleep.
Happy Aging includes a Hormone Harmony Blend™ that doesn’t exist in IM8’s formula. Three actives, one job:
IM8 includes none of these. AG1, the brand IM8 compares itself to, doesn’t either. Most "foundational" formulas skip them. They were designed for a body that holds steady from 25 to 65, which is not the body most women carry.
05 NAD+ difference
Inside the pouch: six trademarked blends, three capsules, thirty actives.
Both products claim a longevity layer. They are not the same layer.
IM8’s CRT8™ complex pairs Spermidine with Trans-Resveratrol. A credible autophagy stack. The premise is to support the body’s cellular cleanup process, the system that recycles damaged cell parts.
Happy Aging’s NAD+ Super Booster Longevity Blend takes a different mechanism: it directly raises NAD+, the molecule the body uses to keep cells running. Four actives, working together:
IM8’s formula contains none of NMN, NR, or direct Liposomal NAD. They overlap on Trans-Resveratrol; the rest is different chemistry. CRT8 is an autophagy bet, an indirect support for cellular cleanup. Happy Aging’s NAD+ blend is a direct intervention on the molecule that declines with age.
If "longevity" is the buying reason, that distinction is the whole conversation. NAD+ depletion is one of the twelve hallmarks of aging cataloged in the cellular-biology literature, and NAD+ levels collapse measurably from your thirties onward. The science on raising them is built around precursors like NMN and NR specifically.[8][9] A formula calling itself "longevity" without those is naming a category, not addressing a mechanism.
06 Skin & brain
When women describe what they notice changing first, two things come up in nearly every conversation: the face that doesn’t bounce back like it used to, and the word that won’t come.
Happy Aging treats both as foundational, not afterthoughts. Two more named blends carry the work: Skin Glow Complex™ and Brain Booster Blend™.
IM8 includes AstaPure® astaxanthin as its skin-relevant ingredient. Useful, but not the same chemistry. AstaPure is a single antioxidant; Happy Aging’s blend targets hydration, vascular tone, and structural collagen support together.
IM8’s formula lists an adaptogen and mushroom complex at the category level. Happy Aging names the three actives, and the doses sit in a dedicated 100–110 mg blend.

08 The receipts
When you take a daily supplement, contamination is a year-over-year accumulation, not a one-day risk. Even trace amounts of lead, cadmium, or arsenic build up in tissue if the daily dose carries them.
Consumer Reports recently flagged this in a 23-product supplement audit: more than two-thirds had concerning lead levels per serving, with several over 1,200–1,600% of safe daily limits.[5] The customer never sees that, unless the company publishes the test.
Happy Aging publishes the actual third-party Certificate of Analysis for every batch. Lot 2508019, tested by ICP, results below the daily limit by an order of magnitude:[1]
Plus: Gluten allergen tested at less than 20 ppm. E. coli and Salmonella negative. Total aerobic and yeast/mold counts well within USP limits.
IM8 publishes a Certificate of Analysis too[4]. Credit where it’s due, and a meaningful step above the average powder brand. The numbers tell a different story up close. Happy Aging’s lead measures at 0.04 mcg per daily dose against a 5 mcg limit[1]. Less than one percent of allowed. AG1, the brand IM8 itself uses to show why testing matters, was independently flagged by ConsumerLab at 2.1 mcg per serving.[6] A 50× difference in the same category.
Numbers that low aren’t accidental. They come from a smaller, focused formula with less surface area for contamination, not a 75-ingredient kitchen sink that has to clean inputs from dozens of suppliers.
09 Format
Worth saying out loud because it’s a real daily-life difference.
Happy Aging
3 vegetable capsules with breakfast. No mixing, no taste, no morning ritual to build.
IM8
1 scoop powder mixed in water, taken in the morning. Acai-cocoa flavor with Reb M sweetener.
IM8 is a powder. One scoop, mixed in water, taken in the morning. The taste sits at a single acai-and-cocoa profile, better than most greens powders, which run from "stevia aftertaste" to "medicinal" in unfiltered reviews. Some women love this ritual. The morning shake is part of the routine.
Happy Aging is three vegetable capsules. No taste, no mixing, no texture, no bitter finish to chase with coffee. Three caps with breakfast and you’re done.
Both formats deliver actives. The practical reality is one-sided. Powders only work if you drink them, every day, and the dropout rate on greens powders is higher than the brands publicly admit. Travel breaks the routine. Bad-tasting batches break it faster. Mornings get skipped. The compounding daily ritual is where supplements work, and capsules win that match by a wide margin.
One more practical note: powders need flavoring systems, sweeteners, and stabilizers to be drinkable. Even with Reb M, IM8 still needs an "acai-cocoa" cover, because seventy-five-line ingredient stacks taste exactly like a seventy-five-line ingredient stack. Three vegetable capsules don’t need a flavor system. No Reb M, no natural flavor, no thickener.
10 Built by an MD
Dr. Daniel Yadegar is Happy Aging’s Chief Medical Advisor. Harvard-trained, practicing internal medicine and longevity in New York City. He built the formula around one complaint women keep raising at this stage of life: "I’m doing what worked at 35 and it’s not working anymore."

Most women at this stage tell me the same thing. The diet, the workout, the routine: nothing changed except the body responding to it. They don’t need another multivitamin. They need support for what’s shifting.

The product is the answer to that conversation. Six blends, thirty actives, three capsules. Chosen because women kept coming back to him saying which pieces helped most.
It’s the formula he gives his sister. We borrow that line because it’s true.
11 Provenance
A daily formula tells you what it is in two ways: by what’s on the label, and by what the label leaves out. Generic ingredient names answer fewer questions about supplier, form, and the clinical dataset behind the line item. Trademarked or sourced ingredients usually mean a tighter spec.
IM8 uses several branded ingredients in its formula: Quatrefolic® (a patented 5-MTHF folate), VegD3® (lichen-derived vitamin D3), FloraSMART® (a clinically-studied postbiotic from heat-treated L. casei 327), and AstaPure® (microalgae-sourced astaxanthin).[3] A sensible move. Named forms make claims more replicable.
Happy Aging takes the same approach, structured differently. Instead of branded individual ingredients dropped into a generic blend, the formula is built around six trademarked blends, each defined by a specific job and tested as a unit:
600–660 mg / serving
Liposomal NAD, NR Chloride, Trans-Resveratrol (Japanese Knotweed), Reduced β-NMN.
130–144 mg / serving
Urolithin A, PQQ disodium salt, TMG, CoQ10, D-Ribose, L-Glutathione.
185–203 mg / serving
Hyaluronic Acid, Grape Seed Extract, Bamboo Silica.
125–137 mg / serving
Maca Root 10:1, Chaste Berry / Vitex (Fruit), Pumpkin Seed.
100–110 mg / serving
L-Theanine, Lion’s Mane (10:1), Ginkgo biloba (Leaf).
270–297 mg / serving
Organic Goji, Acai, Maqui, Blueberry, Blackberry, Strawberry, Raspberry, Acerola, Spirulina, Beet Root.
Every batch ships with a published Certificate of Analysis from Health Genesis Corporation (Davie, Florida).[1][15] Lot numbers, target weights, ingredient COAs, heavy-metal results, gluten testing, microbiology. The full record, not a marketing claim.
12 Price & value
IM8 lands at $89/month on subscription, about $2.96 per serving.[2] Their pouch format drops to $79. Their travel sticks stay at full price.
Happy Aging’s anchor offer is Buy 2, Get 1 Free: three months for $158 instead of $237, which works out to about $53/month. The cheapest way to run the protocol, and it lines up with the timeline most women need to see results. Meaningful change typically shows up between week 6 and week 12.
If you’d rather start smaller, the 1-month subscription is $79/month with all the same gifts and free shipping. Cancel anytime.
Both ship US fast and free on subscription. Happy Aging adds free shipping on the 3-month bundle as well. Cancel anytime, no fixed contract.
IM8’s starter includes a Forever Jar or 30 sachets, plus a 5-pack of complimentary sachets and the signature red cup. Happy Aging’s 3-month bundle includes a Travel Bag and a Metal Jar. The practical accessories women said they use, not the marketing ones.
IM8 ships a single acai-cocoa profile, sweetened with Reb M (no stevia). A better drink than most greens powders.
Happy Aging is vegetable capsules. There is no taste. Its own kind of feature.

13 Verdict
IM8 helped raise the standard for a "foundational" daily. Transparent COA, branded ingredients, four-tier gut system. That’s the right direction for the category, and we won’t pretend otherwise.
It’s also positioned to be everything for everyone. The multivitamin, the greens, the electrolyte mix, the recovery drink, the joint formula. One scoop. A reasonable answer for an unisex audience whose primary need is broad coverage. A poor answer for the woman whose body is changing in specific, predictable ways.
Where Happy Aging wins:
If you’re a woman, the answer is Happy Aging. If you want a generic unisex multi-plus-greens, IM8 is well-built for that. We’ll be honest about which question we’re here to answer.

14 FAQ
If you’re a woman, Happy Aging. The formula was designed specifically around the female endocrine system, NAD+ aging, skin, and brain. IM8 is a credible unisex multi-plus-greens that covers a generic adult’s nutritional floor. It doesn’t carry Maca, Vitex, NMN, NR, or any of the things women came to a longevity supplement for. Most Happy Aging customers switched in from another brand. Almost none switch back.
Yes, about 75 vs Happy Aging’s ~30. That’s also the problem. The bigger the ingredient list, the lower the dose of any single active and the more generic the formula has to be to satisfy "everyone." Happy Aging picked the 30 actives that move what we said we’d move, at meaningful doses, organized into six trademarked blends tested as units. IM8’s extra forty-five ingredients are mostly RDI-coverage you can get from any multivitamin, and most women already take one.
Vitamin D is best dosed individually based on your blood level. Some women need more (4,000-5,000 IU) and some need less if already in range. We left it out of the Happy Aging formula on purpose so the dose can be tuned by you and your doctor. The IM8 approach (2,000 IU / 50 mcg built in alongside 100 mcg K2) lands at a useful general-purpose dose, but it isn’t the right answer for everyone. We kept it modular.
Most women report the first changes in week 2–3 (energy, sleep, less afternoon crash). The hormonal and skin changes show up between week 6 and week 12. That’s why the 3-month bundle exists. Give it a full 90 days before deciding. If it’s not working, the 30-day refund is unconditional.
Smaller, focused formula instead of a 75-ingredient kitchen sink. We’re paying for the actives that move what we said we’d move, not for every base nutrient. The Buy 2, Get 1 Free bundle lands at about $53/month ($158 for three) vs $89 for IM8. Roughly $432/year saved.
