Edited by Elaine Fletcher, Researcher

Quick answer: Of the best longevity supplement stacks sold in the US in 2026, our pick is the Eternal Elixir pairing of NMN 500mg and Trans-Resveratrol 600mg. Both doses are declared per capsule, both bottles hold 90 capsules, and the pair costs $109.98, which clears our $100 free-shipping line. Thorne’s Longevity Stack ($102) is the pick if you want nicotinamide riboside (NR) instead of NMN from an established practitioner brand. Double Wood’s NMN and resveratrol bundle ($62.01) is the lowest-priced two-product stack here, at a smaller NMN dose. If you would rather take one bottle, our NMN Advanced Longevity Complex puts six actives in a two-capsule serving for $2.17 a day.

Eternal Elixir makes three of the seven options below, including our pick, which sits first. Every figure for the other stacks comes from the brand’s own product or bundle page, read on September 25, 2026. We did not lab-test any of these products, and prices change, so check the live page before you buy. Here is how we write and review content.

Best longevity supplement stacks compared: price and cost per day

A stack is two or more products taken together, so the sticker price tells you little until you know how many days it lasts. Where a label states the serving, we divided the price by the servings. Where it doesn’t, we say so. Prices are as of Sep 2026.

Add NMN 500mg to cart · $49.99

Two things stand out. The pre-built bundles mix products with different serving counts, so they rarely run out on the same day. And the spread in daily cost is huge, from under $2 to more than $27, mostly because of how many products sit in the box.

1. Eternal Elixir NMN 500mg + Trans-Resveratrol 600mg: our pick

What you get: NMN 500mg, 90 capsules for $49.99, and Trans-Resveratrol 600mg, 90 capsules for $59.99, one capsule per serving. Together that is $109.98.

It is our pick for three reasons. Both doses are declared per capsule, so nothing hides in a blend. The resveratrol is 98% pure trans-resveratrol from Polygonum cuspidatum root, the form used in most research. And NMN costs $1.11 per gram here, lower than any other NMN product in this list.

One honest limit on the arithmetic: our NMN page asks you to follow the serving printed on the bottle in hand, so we quote NMN per capsule ($0.56) rather than per day. The resveratrol label states one capsule per serving, which is $0.67 a day. If you prefer one capsule for both, our VitaSolutions NMN + Resveratrol 1100mg lists 500 mg of NMN and 600 mg of trans-resveratrol per labeled serving for $35 a bottle.

Because both bottles hold 90 capsules, the pair is simple to reorder. Buying two bottles of each takes 10% off, which brings a set of one NMN and one resveratrol bottle to $98.98, and three or five bottles take 15% or 20% off.

The evidence, stated plainly. In a 12-week randomized, placebo-controlled trial in GeroScience (Morifuji and colleagues, 2024), 60 older adults took 250 mg of NMN a day or a placebo. Blood NAD+ rose, four-meter walking time was shorter and sleep-quality scores improved on NMN. The main outcome, a stepping test, did not differ from placebo. The authors worked for the company that made the NMN. A 60-day trial in 80 healthy middle-aged adults (Yi and colleagues, 2023) found blood NAD rose at 300 mg, 600 mg and 900 mg a day, most at the two higher doses. Evidence level: small human trials that measure NAD+ and short-term function. NMN has not been shown to extend human lifespan, and neither has resveratrol.

• Pros: both doses declared per capsule, 90 capsules in each bottle, the lowest NMN price per gram in this list, and the order clears free US shipping
• Cons: two bottles to take, no methyl donor or CoQ10 included, and Eternal Elixir is a younger US brand than Thorne

Best for: most people building a first longevity stack who want the core NAD+ and polyphenol pair with doses they can see. Our guides to the best NMN supplements and best resveratrol supplements compare each half on its own, and our NMN versus resveratrol guide explains why they are paired.

2. Thorne Longevity Stack: NR instead of NMN

What you get: Thorne’s Longevity Stack holds ResveraCel and CoQ10, one 60-capsule bottle of each, for $102. A two-capsule serving of ResveraCel lists 415 mg of nicotinamide riboside hydrogen malate, 150 mg of trans-resveratrol, 250 mg of quercetin phytosome and 85 mg of betaine (TMG). Thorne’s directions are two ResveraCel capsules a day and one CoQ10 capsule once or twice a day.

At the two-capsule serving, a 60-capsule bottle of ResveraCel lasts 30 days. Bought alone, ResveraCel is $60, or $2.00 a day. The CoQ10 bottle lasts 30 to 60 days, depending on whether you take one capsule or two, so the bundle does not run out on a single date.

The formula logic is sound: an NAD+ precursor, a polyphenol and a methyl donor in one capsule, with CoQ10 covering mitochondrial energy separately. The trade-off is that it uses NR rather than NMN, at a lower resveratrol dose than our 600 mg capsule. Our Thorne review covers the brand in more depth, and our NR comparison covers other NR products.

The NR in ResveraCel has its own trial record. In an eight-week randomized, placebo-controlled trial in Scientific Reports (Conze and colleagues, 2019), 140 healthy overweight adults took 100 mg, 300 mg or 1,000 mg of NR chloride a day or a placebo. Whole blood NAD+ rose by 22%, 51% and 142% at those doses within two weeks. NR maker ChromaDex funded the study. ResveraCel lists its NR as hydrogen malate, a different salt, and gives the weight of the salt rather than of NR alone, so its dose doesn’t map exactly onto that trial.

• Pros: four actives in ResveraCel, CoQ10 adds a separate pathway, established practitioner brand
• Cons: $2.00 a day for ResveraCel alone, NR instead of NMN, and two bottles with different run times

Best for: buyers who prefer NR and want a pre-assembled stack from a long-running brand.

3. Double Wood NMN + Resveratrol bundle: lowest bundle price

What you get: Double Wood’s NMN and Resveratrol bundle for $62.01, down from $68.90, which is the price of one bottle of each. Its NMN page states 250 mg of NMN per serving and directs two capsules a day, and its $48.95 bottle holds 30 servings. Its Resveratrol gives 500 mg of Japanese knotweed resveratrol per two-capsule serving, standardized to 50% trans-resveratrol, with 60 servings in a $19.95 bottle.

So the bundle covers 30 days of NMN and 60 days of resveratrol. The NMN dose is half of one of our capsules, and at list price it works out to $6.53 per gram of NMN against $1.11 for ours. The resveratrol is good value at $0.33 a serving for 250 mg of trans-resveratrol. Double Wood posts certificates of analysis on its product pages, ships free over $30 and offers a 30-day money-back guarantee. Its separate three-product Longevity Stack (NMN, TMG and SPM) showed as sold out when we checked.

• Pros: lowest bundle price here, lab reports posted, low free-shipping threshold
• Cons: 250 mg NMN serving, bottles run out at different times, and its three-product Longevity Stack is sold out

Best for: budget buyers happy with a 250 mg NMN serving. Our Double Wood Supplements review covers the rest of its range.

4. Eternal Elixir NMN Advanced Longevity Complex: one bottle instead of a stack

What you get: NMN Advanced Longevity Complex, 60 vegan capsules for $64.99, 30 servings of two capsules. Each serving lists 500 mg of NMN, 250 mg of TMG, 200 mg of pterostilbene, 100 mg of trans-resveratrol, 100 mg of quercetin phytosome and 50 mg of apigenin, 1,200 mg of actives in all. That is $2.17 a day.

This is for people who like the idea of a stack but won’t keep up with several bottles. It covers the NAD+ precursor, a methyl donor and four polyphenols and flavonoids in one serving. The trade-off: it costs more per day than our two-bottle pair, the resveratrol dose is 100 mg rather than 600 mg, and the ratios are fixed. Our product page says the ingredients have been studied individually and this exact six-ingredient formula has not been clinically tested. Our guide to the best pterostilbene supplements covers the resveratrol relative it includes.

• Pros: six actives in one bottle, TMG included, lowest up-front price of any complete stack here
• Cons: $2.17 a day, a 30-day bottle, and fixed ratios you can’t adjust

Best for: buyers who want the widest coverage in a single bottle.

5. Eternal Elixir Spermidine 10mg + Ca-AKG 500mg: a second layer

What you get: Spermidine 10mg and Ca-AKG 500mg, 60 capsules each for $49.99, one capsule per serving. Together that is $99.98 for 60 days, or $1.67 a day. The spermidine is declared as 10 mg of spermidine trihydrochloride, a salt form.

This is not a starter stack, and we would not sell it as one. It is something to add once an NAD+ base is in place. The honest problem is the evidence. The largest human spermidine trial, SmartAge (Schwarz and colleagues, JAMA Network Open, 2022), gave 100 adults aged 60 to 90 a wheat germ extract with 0.9 mg of spermidine a day or a placebo for 12 months. Memory did not change compared with placebo. The lifespan results for Ca-AKG come from mice (Asadi Shahmirzadi and colleagues, Cell Metabolism, 2020), and no human lifespan data exist. Both of our product pages say so.

• Pros: targets a pathway the NAD+ pair doesn’t, doses declared per capsule, both bottles run 60 days
• Cons: thin human evidence, and $1.67 a day for two actives with less human data than NMN

Best for: experienced buyers adding a second layer with realistic expectations. Our spermidine comparison, spermidine benefits guide, Ca-AKG comparison and Ca-AKG evidence review go deeper.

6. Dr. Hyman Longevity and Biohacking Stack: basics plus longevity, at a price

What you get: a 12-product bundle sold as a 30-day supply for $810.50 (regular price $900.56). It includes Vitamin D Supreme, Magnesium Glycinate, Omega-3 Rejuvenate, a multivitamin, a synbiotic, astaxanthin, CoQnol 200 and Wonderfeel Youngr NMN, among others.

This stack does something different from the rest. It covers foundational nutrients first, then adds longevity products on top. If you think the basics should come before anything else, that is a fair position, and this bundle puts it in one order. The price is the catch: about $27.02 a day, most of it for the number of products in the box. Our Wonderfeel Youngr NMN review covers the NMN product it includes.

• Pros: the broadest coverage here, foundational nutrients included, one order
• Cons: by far the highest price, and much of the box is general nutrition rather than longevity actives

Best for: buyers who want everything in one delivery and for whom price is not the limit.

7. Single-active start: best for learning what works for you

There is a real case for not stacking at first. Start four actives at once and you can’t tell which one did anything. Starting with one for 8 to 12 weeks, then adding a second, is slower but tells you more.

It is also the cheapest way in. One bottle of NMN 500mg at $49.99 holds 90 capsules, and one bottle of Nicotinamide Riboside 500mg at $59.99 holds 60 one-capsule servings. Our NMN versus NR guide helps you choose between the two precursors.

• Pros: lowest cost to start, the only way to see what each active does, easy to build on
• Cons: not a stack, and the slowest route to a full routine

Best for: methodical buyers who want to know what each ingredient is doing before adding the next.

How to build your own longevity stack, step by step

If you build a stack yourself, the order matters more than the brand. This is the sequence we suggest, and it is the one our own range is built around.

1. Start with one NAD+ precursor for 8 to 12 weeks. Pick NMN or NR, not both. That covers the time frame in which the trials above saw blood NAD+ rise, and it is short enough to decide whether to continue.
2. Add a polyphenol next. Trans-resveratrol or pterostilbene is the usual partner. Adding it second means you know how you felt on the precursor alone.
3. Consider a methyl donor. TMG is the common addition to NMN. Our Advanced Complex and Thorne’s ResveraCel already include it, so you can skip a separate bottle if you use either.
4. Add a second layer last, if at all. Spermidine and Ca-AKG have the least human evidence, so they belong at the end of the list.
5. Keep notes. Write down when you started each product, how you sleep and how your energy feels. If your doctor orders blood tests, bring the list of what you take.

Budget the stack before you start. From the table above, a two-product stack runs from $62.01 to $109.98 per order, and a one-bottle option is $64.99 a month. Buying two, three or five bottles of any Eternal Elixir product takes 10%, 15% or 20% off, which matters once you know a product is worth keeping.

How we ranked the best longevity supplement stacks

Eternal Elixir makes our pick and two other options here, so here is exactly what we checked for every stack:

• Label clarity: is each active named by form and amount, or hidden in a blend?
• Cost per day: the price divided by the servings the label states, and a clear note where that can’t be done
• Availability: is it in stock and shipping in the US now?
• Room to build: can you add to the stack without doubling up on actives?
• Brand record: how long the brand has sold supplements and what it publishes about testing

We did not run lab tests or trials, and we have no first-hand experience of the competitor bundles. What we did was read labels, prices and stock, then do the arithmetic.

What belongs in a longevity supplement stack

Most longevity stacks are built in layers. The first is an NAD+ precursor, NMN or NR, because NAD+ levels fall with age and the enzyme family called sirtuins depends on it. Our NAD+ supplement comparison covers the precursors.

The second layer is a polyphenol, usually trans-resveratrol or pterostilbene. It is included on the idea that it works alongside NAD+ on sirtuins, which is why the pairing appears in almost every stack here. Human evidence for resveratrol is modest: the longest trial we know of, RESHAW, gave 125 postmenopausal women who completed it 75 mg twice a day and found a small gain in spine bone density after 12 months.

The third layer, spermidine and Ca-AKG, has the least human evidence, so add it last. A methyl donor such as TMG is the fourth consideration, because the body uses methyl groups when it processes NMN. That is why ResveraCel and our Advanced Complex include it.

Beyond all of this, sleep, exercise and diet do more for healthy aging than any capsule in this list. Many people also start with foundational nutrients such as vitamin D and omega-3s, which we don’t sell. Our guide to the best longevity supplements and our supplement dose gap report, which compares label doses with trial doses, are good next reads.

Safety: when to check with your doctor first

Talk to your doctor before starting any stack if you are pregnant or breastfeeding, take prescription medicines or have a long-term health condition. Thorne’s warnings for both products in its stack say to consult a practitioner if pregnant and not to use them if you are sensitive to any ingredient. A stack raises the number of ingredients you take at once, so bring the full labels to that conversation, not just the product names.

Start one product at a time so you can tell which one caused a reaction, and stop if you notice anything you didn’t expect. None of the products in this list, ours included, has been clinically tested as a finished stack.

Frequently asked questions about longevity supplement stacks

What is the best longevity supplement stack for adults?

Our pick is the Eternal Elixir pairing of NMN 500mg and Trans-Resveratrol 600mg, which we make: 500 mg of NMN and 600 mg of 98% trans-resveratrol per capsule, 90 capsules each, $109.98 for both. If you prefer NR, Thorne’s Longevity Stack ($102) is the alternative. If you want one bottle, our NMN Advanced Longevity Complex costs $2.17 a day.

Add NMN 500mg to cart · $49.99

What are the top 3 supplements for longevity?

No three supplements have been shown to extend human life. Among the popular longevity actives, NAD+ precursors (NMN and NR) have the most human trial data, and it mostly shows higher blood NAD+ rather than long-term health outcomes. Resveratrol is the usual partner. Spermidine and Ca-AKG have the least human evidence.

Do supplement stacks actually work?

There are almost no trials of stacks as a whole. The evidence comes from trials of single ingredients, such as NMN raising blood NAD+ over 8 to 12 weeks. A stack combines those ingredients on a reasonable idea, but the combination itself has not been tested, including ours.

How much does a longevity supplement stack cost per month?

Where a label lets us work it out, our NMN Advanced Longevity Complex costs $64.99 for 30 days, our Spermidine and Ca-AKG pair $99.98 for 60 days, and Thorne’s ResveraCel $60 for 30 days. Dr. Hyman’s bundle is $810.50 for 30 days. Our NMN and resveratrol pair is $109.98 for 90 capsules of each.

Should I buy a pre-built stack or build my own?

Pre-built bundles are simpler and sometimes discounted. Building your own lets you control each dose, check the cost before you buy and drop one active without dropping the rest. If you have never taken any of these ingredients, start with one.

Can you take NMN and resveratrol together?

They are routinely sold and taken together, and the pairing is the basis of most longevity stacks. Follow each product’s label and talk to your doctor before combining supplements, especially if you take prescription medicines.

Add Trans-Resveratrol 600mg to cart · $59.99

Is NMN or NR better for a longevity stack?

Both raise blood NAD+ in human trials, and we know of no long-term trial comparing them head to head. The NMN trials we cite used 250 mg to 900 mg a day, and the NR trial used 100 mg to 1,000 mg. Choose on dose, price and label clarity. Our NMN versus NR guide covers the details.

Which longevity blend supplement is the best?

Among single-bottle blends, our pick is the Eternal Elixir NMN Advanced Longevity Complex, which we make. Each two-capsule serving lists 500 mg of NMN with TMG, pterostilbene, trans-resveratrol, quercetin phytosome and apigenin, at $64.99 for 30 servings. A blend trades flexibility for convenience: you can’t change one dose without changing them all.

How long before a longevity stack does anything?

The NMN trials above ran 60 days and 12 weeks, and blood NAD+ rose within that time. Changes you can feel were smaller and less consistent. Give any change at least 8 to 12 weeks, and change one thing at a time.

The verdict: which longevity supplement stack should you buy?

Our pick is the Eternal Elixir pairing of NMN 500mg and Trans-Resveratrol 600mg: both doses declared per capsule, 90 capsules in each bottle, the lowest NMN price per gram in this list and free US shipping on the $109.98 order. The others each win on something narrower:

• If you prefer NR: Thorne’s Longevity Stack at $102.
• If price comes first: Double Wood’s NMN and resveratrol bundle at $62.01, at a 250 mg NMN serving.
• If you want one bottle: our NMN Advanced Longevity Complex at $2.17 a day.
• If you want everything in one order: Dr. Hyman’s bundle at $810.50 for 30 days.
• If you are starting from zero: one bottle of a single active for 12 weeks before adding anything.
