Codeage Review 2026: An Honest Longevity Buyer’s Take

Last updated: August 15, 2026 · Published by Eternal Elixir

Codeage currently lists roughly 180 separate products on its own store — eight of which are NAD-precursor formulas priced from $24.99 to $99.99. That single fact explains why most people searching for a Codeage review come away more confused than when they started.

The brand is not hard to evaluate because the quality is unclear; it is hard to evaluate because the catalog is enormous and the sub-brands overlap. This Codeage review maps the range as it actually stands, using prices and label doses read directly from Codeage’s live storefront on August 15, 2026.

What the Public Ratings Actually Say in Any Codeage Review

Start with the raw signal rather than the marketing. On Trustpilot, codeage.com carries a 4.6 out of 5 rating across 878 reviews. On iHerb, a single Codeage SKU — the A, D, K Vitamins+ — holds 4.8 out of 5 from 1,132 ratings. The brand is stocked by The Vitamin Shoppe, Walmart, Sam’s Club, Amazon and iHerb, which is a meaningful signal in itself: national retailers apply their own supplier vetting before a brand reaches shelf space.

The recurring praise in those public reviews clusters around three things: clean-label formulas without unnecessary fillers or artificial colors, powders that dissolve without grit, and capsules that sit well on an empty stomach. The recurring complaints cluster just as tightly: price relative to grocery-store brands, large capsules, and multi-capsule serving sizes.

Worth noting is what the search results for a Codeage review are mostly made of: retailer product pages, a Trustpilot profile, a Reddit thread and customer-review sections. Those are useful as sentiment, but none of them puts the catalog side by side or normalizes doses across products. That gap is what the rest of this page is for.

None of that is unusual for the premium end of the US market. What matters more for a buying decision is whether the doses justify the price, and that is where a proper Codeage review has to get specific. If you want the wider category context first, our roundup of the best NAD+ supplements covers how the leading NAD-precursor formulas compare on dose and format, and our Double Wood Supplements review looks at a very different pricing philosophy in the same category.

Eight NAD Formulas, One Brand: The Codeage Longevity Range Mapped

This is the part no other Codeage review appears to publish, and it is the single most useful thing a prospective buyer can see. Codeage does not sell “an NMN supplement.” It sells eight overlapping NAD-precursor products across capsules, powders and liquids, at four different dose levels. Here is the full map, with every dose expressed in the same unit — milligrams of the named NAD precursor per labeled serving — and every price in USD per container, read from the live product pages on August 15, 2026.

Best for… The $29.99 Amen NMN is the entry point for a plain 500 mg NMN serving. The $59.99 Liposomal NMN 1000 Powder carries the highest labeled dose in the range at the lowest price for that dose. The $79.99 and $99.99 Platinum products are combination formulas — you are paying for trans-resveratrol, quercetin, TMG and B vitamins alongside the precursor, not for more precursor. The $89.99 Liposomal NMN Multivitamin makes sense only if it genuinely replaces your existing multivitamin.

Two caveats before you use that table. Servings per container differ between these SKUs, so the price column is not a cost-per-serving figure — check the container size on the label before comparing. And one product, the $39.99 Liposomal NMN, does not state an NMN quantity on its listing at all, which is worth knowing before you buy it.

What “Liposomal Delivery” Does and Doesn’t Tell You

Roughly half the Codeage catalog carries the brand’s liposomal delivery branding. It is the single most repeated claim across the range, so it deserves scrutiny rather than assumption.

Liposomal delivery means the active ingredient is paired with phospholipids intended to improve how much of it survives digestion. It is a real formulation approach with a real rationale, and it is the claim most often repeated back in third-party coverage without examination. What it is not is a substitute for dose disclosure. A liposomal product with an undisclosed active quantity tells you less than a plain-capsule product with a clearly printed milligram figure, no matter how sophisticated the carrier system sounds.

The honest position is this: the published human evidence supports the ingredients themselves far more strongly than it supports any particular delivery format. A double-blind randomized trial in GeroScience gave 60 older adults 250 mg of NMN per day for 12 weeks and found significantly higher blood NAD+ levels than placebo, alongside a shorter four-meter walking time and better sleep-quality scores — though the study’s primary outcome, a stepping test, showed no significant difference (PMID 38789831). That is a plain oral dose, not a liposomal one, at a quarter of the milligram figure on Codeage’s high-potency SKUs.

The same pattern holds elsewhere in the range. Codeage’s Nanofood Liquid Liposomal Glutathione delivers 100 mg of reduced glutathione per serving at $24.99. The best-known human trial on oral glutathione, a six-month double-blind study of 54 adults published in the European Journal of Nutrition, used 250 mg or 1,000 mg per day and reported roughly 30–35% increases in erythrocyte, plasma and lymphocyte glutathione at the higher dose (PMID 24791752).

Format aside, dose is the variable that trial actually manipulated. For a like-for-like look at what the category offers, see our comparison of the best glutathione supplements.

Codeage’s Hair Vitamins Platinum at $59.99 is a good example of the brand at its most interesting: it combines Lustriva, spermidine, AstraGin, biotin, collagen and keratin in one formula. Spermidine in particular is a legitimately well-studied longevity compound — we cover the standalone options in our guide to the best spermidine supplements. The trade-off with a stack like that is the same one that runs through this entire Codeage review: more ingredients per capsule usually means less of each one.

Where Codeage Fits Against a Focused Longevity Range

Codeage’s positioning is breadth. It sells collagen, probiotics, multivitamins, minerals, sport formulas, pet supplements and longevity actives under one roof, including a $42.99 Multi Collagen+ with five collagen types plus vitamin C, biotin and hyaluronic acid, and a $79.99 Centenarian 100 built around 500 mg of fisetin and 200 mg of resveratrol.

Eternal Elixir takes the opposite approach: a deliberately short list of single-purpose longevity and nootropic formulas, third-party tested, shipped across the United States. That difference matters most when you already know what you want. If your shelf needs one NMN, one antioxidant and one skin-support product, a 180-SKU catalog is friction rather than choice.

This is the fairest framing for any Codeage review: the two ranges are not really competing on quality, they are competing on how much decision-making they hand back to you. Codeage optimizes for a household that wants everything from one supplier. A focused longevity range optimizes for someone who has already decided what belongs on the shelf and wants the shortest path to it.

Concretely: Eternal Elixir’s NMN 500mg capsules are $49.99 for 90 capsules at 500 mg per capsule, currently reduced from $64.99.

That sits between Codeage’s $29.99 Amen NMN and its $79.99 Liposomal NMN Platinum at the same 500 mg labeled dose.

Eternal Elixir’s Reduced L-Glutathione 2000mg is $39.99 and supplies 2,000 mg of reduced glutathione per two-capsule serving — twenty times the per-serving figure on Codeage’s liquid glutathione, in a different format. And on the skin side, where Codeage leans on collagen, Eternal Elixir’s Hyaluronic Acid 200mg capsules provide 200 mg per capsule with 200 capsules per bottle at $69.99.

On the collagen question itself, the evidence is reasonably encouraging. A systematic review and meta-analysis in Cureus pooled 14 randomized controlled trials covering 967 participants and found that 12 weeks of oral hydrolyzed collagen improved skin moisture and elasticity relative to placebo (PMID 38192916). That supports the ingredient category broadly; it does not test any specific finished product, Codeage’s or anyone else’s.

Two other brand comparisons in this series may be useful alongside this one: our Thorne review examines a clinician-facing brand with a similar premium position, and our Life Extension review looks at the longest-established name in the category.

A Codeage Review Verdict: Who Should Buy and Who Shouldn’t

Buy Codeage if you want one supplier for a wide household routine — multivitamins, probiotics, collagen and a longevity active in a single order — and you are comfortable reading labels carefully to pick between overlapping SKUs. The public ratings are strong, retail distribution is broad, and the clean-label formulation approach is consistent.

Look elsewhere if you want a short, unambiguous longevity shelf. The eight-SKU NAD range is the clearest illustration: choosing between a $24.99 liquid at 100 mg and a $99.99 capsule at 500 mg of a different molecule requires research most buyers should not have to do.

A focused range removes that decision entirely, which is the whole argument for a short shelf.

The bottom line of this Codeage review: this is a competent, widely-stocked brand with a genuinely broad catalog and a consistent clean-label approach. The weakness is navigational, not qualitative — and it is entirely fixable by reading two numbers before you buy.

The value question depends more on dose than on brand. Read the milligram figure per serving and the servings per container on any product you are considering — from Codeage, from Eternal Elixir, or from anyone else — and the comparison usually resolves itself. Our roundup of the best NMN supplements applies exactly that method across the category.

Frequently Asked Questions

Is Codeage a legit company?

Yes. Codeage is an established US supplement brand that sells through its own storefront and through major national retailers including The Vitamin Shoppe, Walmart, Sam’s Club, Amazon and iHerb.

Its public review profile is broadly positive, with a 4.6 out of 5 Trustpilot rating across 878 reviews at the time of writing.

Do Codeage hair vitamins work?

Public ratings for Codeage’s hair products are generally positive, and the Hair Vitamins Platinum formula at $59.99 contains ingredients with real research behind them, including biotin, collagen, keratin and spermidine. As with any hair supplement, individual results vary, effects are gradual rather than immediate, and no supplement is intended to treat a medical cause of hair loss.

Is Codeage multivitamin good?

Codeage’s multivitamins review well publicly — the A, D, K Vitamins+ holds 4.8 out of 5 from over 1,100 iHerb ratings. The main practical consideration is serving size: several Codeage multivitamin formulas require multiple large capsules per day, which is the most common complaint in customer reviews across the range.

Is Codeage collagen peptide good?

Codeage’s Multi Collagen+ at $42.99 combines five collagen types with vitamin C, biotin, hyaluronic acid and amla berry, and its collagen powders are among the brand’s best-reviewed products. Pooled trial evidence supports oral hydrolyzed collagen for skin moisture and elasticity over roughly 12 weeks, though that research covers the ingredient rather than this specific product.

Is Codeage worth the price compared to cheaper brands?

It depends entirely on which product you pick, which is the central finding of this Codeage review.

Within the brand’s own NAD range, a 500 mg NMN serving costs $29.99 in the Amen line and $79.99 in the Platinum line — the difference is the added trans-resveratrol, quercetin and TMG, not extra NMN.

Compare the milligram figure per labeled serving before comparing brands, and the price question usually answers itself. The same arithmetic is worked through for a single-SKU brand in our Wonderfeel NMN review.

How many NAD supplements does Codeage sell?

Eight, as of August 2026: a liquid liposomal NAD, an Amen-branded NMN, a standard Liposomal NMN capsule, an NMN 1000 powder, an NMN 1000 capsule, an NMN Platinum, an NMN Multivitamin and an NMNH Platinum.

They range from $24.99 to $99.99 and from 100 mg to 1,000 mg of precursor per labeled serving. For how those doses stack up outside the brand, see our ranking of the best NAD+ boosters by dose and cost per serving.
