Best Longevity Supplement Stacks Ranked (2026)

I compared the major all-in-one longevity products on the market right now. Here's how they stack up on formulation, clinical evidence, and value.

The longevity supplement market has grown fast enough that you can now choose between several all-in-one products instead of building your own stack bottle by bottle. I've spent time with most of them. Here's my ranking, based on formulation depth, clinical backing, cost per day, and how well each product addresses the 12 hallmarks of aging.

1. DoNotAge daily sachet ($203/month)

15 ingredients across six biological pathway systems. $7.25/day. The most comprehensive hallmark coverage of any single product I've tested.

What sets it apart is the formulation logic. NMN paired with TMG (prevents methylation depletion), SIRT6 Activator (proprietary, only available from DoNotAge), Nitralis for nitric oxide and vascular delivery, spermidine for autophagy, fisetin and quercetin for senolytic activity. The compounds are selected to work as a system, not just a long ingredient list.

Clinical trial showing 76% NAD+ increase with the specific sachet formulation. Most supplement companies cite research on individual ingredients, not their actual product. DoNotAge tested theirs.

Weaknesses: probably underdosed on D3 and magnesium. No liposomal NMN. Highest price on this list.

2. NOVOS Core ($79-99/month)

12 ingredients at $2.63 to $3.30/day. Well-researched formulation with unique additions like microdosed lithium, rhodiola, and pterostilbene.

Published observational data showing 1.26 years of biological age reduction. Solid ingredient transparency with all dosages listed.

Lacks TMG alongside NMN, which means methylation depletion risk. No SIRT6 activator. No nitric oxide booster. More of a broad-spectrum approach than a targeted aging intervention. Good for the price, less comprehensive than DoNotAge.

3. Protocol X by Xandro Lab ($131/month)

Singapore-based. Contains NMN, Ca-AKG, fisetin, taurine, and other compounds. Interesting formulation that includes taurine (a compound with strong mouse lifespan data from a 2023 Science paper) and Ca-AKG as an epigenetic modulator.

Lower NMN dose than DoNotAge and NOVOS. Fewer total ingredients. Less clinical data on the combined formulation. Good regional option in Asia-Pacific but doesn't match the top two on breadth.

4. AgeMate (~$69/month)

Australian brand. NMN-focused powder at the most accessible price point. Straightforward NMN plus supporting compounds.

Less comprehensive than the products above. No senolytics, no SIRT6, no vascular support. A flavored NMN powder with extras. Fine if NMN is your only priority and budget is tight. Not a substitute for a full longevity stack.

5. AG1 ($99/month)

I'm including AG1 because people keep asking about it. $99/month for a greens powder with 75+ ingredients. It's not a longevity product. It doesn't contain NMN, NAD+ precursors, senolytics, or any compound targeting the hallmarks of aging. It's a multivitamin and greens blend. Good for nutritional coverage, wrong category for aging intervention.

The DIY longevity stack option

Building your own stack from individual ingredients gives you full dose control. You pick exact compounds, exact doses, exact brands. The downside is managing 10 to 15 separate bottles, spending $500 to $800/month at retail, and having no clinical data on your specific combination.

If you already know what you want and you've been doing longevity protocols for years, DIY makes sense. If you're starting out or want simplicity, an all-in-one product removes the complexity.

My recommendation

DoNotAge wins on formulation depth and clinical backing. NOVOS wins on price-to-value. If I had to choose one product for someone starting their first longevity protocol, I'd say DoNotAge if they can afford $203/month and NOVOS if they can't.
