Renue By Science NMN Liposomal Capsules Review — Honest Breakdown, Pros, Cons, and Verdict -

Published by Turn Back Clock | Category: Longevity Supplements | Contains an affiliate link

Renue By Science occupies an interesting niche in the NAD+ supplement world: rather than chasing every trending ingredient, the company has focused almost entirely on solving NMN’s absorption problem, offering the same active ingredient across capsule, liposomal capsule, sublingual powder, and gel formats. This review looks specifically at their NMN Liposomal Capsules — sold under the product name LIPO NMN.

Quick Recap: Why NMN and NAD+ Matter

NAD+ is a coenzyme found in every cell in your body, essential for energy production, DNA repair, and the activation of sirtuins — the proteins often called “longevity genes.” NAD+ levels decline by roughly 50% between your 20s and 50s. Because NAD+ itself does not survive digestion intact, supplement companies instead sell NMN, a precursor molecule your body converts into NAD+ after absorption. We cover this in detail in our dedicated NAD+ article.

About Renue By Science

Renue By Science was founded in 2017 by Bryan Nettles, with a stated focus on bioavailability and delivery technology for NAD+ precursors rather than chasing every new trending longevity ingredient. The company is one of relatively few NMN brands offering the same active ingredient across multiple delivery formats — standard capsules, liposomal capsules, sublingual powder, and gel — which makes direct comparison between formats possible within their own product line. Products are manufactured in ISO and cGMP-certified facilities and the company publishes third-party Certificates of Analysis, including raw material, purity, and stability testing.

Product Breakdown: What Is Actually in the Capsule

Active ingredient: β-Nicotinamide Mononucleotide (NMN), 250mg per capsule — 500mg per 2-capsule serving

Delivery method: Proprietary powder-based liposomal encapsulation, described by the company as “LIPO Caps,” using a freeze-dried process intended to protect NMN from digestive enzymes
Other ingredients: Microcrystalline cellulose (bulking agent), sunflower lecithin (emulsifier), rice flour, vegetable capsule (hypromellose)
Format: 90 capsules per bottle, 2-capsule daily serving (a 45-day supply at the standard dose)
Manufacturing: ISO and cGMP-certified facilities, allergen-free, GMP-compliant, with published batch-level Certificates of Analysis
Price: Approximately 4.75 per bottle, working out to roughly .88 per day at the standard 2-capsule serving

The company-sponsored study was a double-blind, placebo-controlled trial in 15 healthy men aged 40 and older, split into three groups of five: Liposomal NMN, Standard NMN, and placebo. After four weeks, the Liposomal NMN group showed an 84% increase in blood NAD+ levels (from 28.6 µM to 52.5 µM), outperforming both the standard NMN group and placebo. Four weeks after stopping supplementation, NAD+ levels had declined but remained elevated at 36 µM versus the original baseline.

The Evidence Behind the Liposomal Claim — An Honest Look

This is where Renue By Science stands out from most competitors: they have actually run a small clinical trial specifically on their liposomal NMN format, rather than relying purely on general liposomal delivery theory borrowed from other compounds.

This is a genuinely useful data point — it is one of the only studies that compares liposomal NMN directly against standard NMN in the same trial, rather than against placebo alone. That said, it is important to be clear-eyed about its limitations: five participants per group is far too small a sample for strong statistical confidence, and the trial was funded and conducted by the company selling the product, which introduces a conflict of interest that independent third-party replication would help resolve. Independent chemistry-focused reviewers have also noted that Renue does not fully publish the specific liposome vesicle size or phospholipid stability data that would let outside parties verify exactly how the encapsulation performs at a technical level.

Taken together: the liposomal mechanism is chemically sound, and Renue has gone further than most brands by running an actual head-to-head trial — but the sample size is small and the source is not independent. Treat the 84% figure as a promising signal worth taking seriously, not as definitive proof.

Pros

Actual head-to-head trial data: One of the few NMN brands to have run a direct liposomal-vs-standard-vs-placebo comparison rather than relying solely on general liposomal theory
Full clinical dose: 500mg per serving sits within the range examined in published human NMN research
Strong testing transparency: Published batch-level Certificates of Analysis with raw material, purity, and stability testing — more thorough than many competitors
Multiple format options: If liposomal capsules do not suit you, the same active ingredient is available from the same company in sublingual powder or gel format
Established, focused company: In operation since 2017 with a clear specialisation in NAD+ precursor bioavailability rather than a broad, unfocused product catalogue

Cons

Supporting trial is small and company-funded: 15 total participants (5 per group) is too small for strong statistical confidence, and the study was conducted by Renue itself rather than an independent lab
Vesicle and stability data not fully public: Independent reviewers have noted that specific liposome particle size and phospholipid stability figures are not fully disclosed, limiting outside verification of the delivery mechanism
Premium pricing: At roughly .88 per day, this sits at the higher end of the NMN supplement market compared to standard (non-liposomal) capsules at the same dose
Marketing language runs ahead of independent verification in places: Bioavailability percentage claims for liposomal delivery in general are sometimes presented without product-specific confirmation — a pattern common across the liposomal supplement category broadly, not unique to this brand

Who This Product Is Best For

This is a strong choice if you want a company that has put its liposomal delivery claim to an actual (if small) clinical test, value batch-level testing transparency, and are comfortable paying a premium for that combination. It particularly suits anyone who has tried standard NMN capsules without noticing results and wants to test whether an enhanced delivery format makes a difference for them personally.

It may be less ideal if budget is your primary concern, or if you want to wait for larger, independently-run trials before paying a liposomal premium — a standard, non-liposomal NMN capsule at the same 250–500mg dose range would be the more economical starting point in that case.

Our Verdict

Renue By Science NMN Liposomal Capsules stand out for actually backing their delivery claim with a real, if small, head-to-head trial — something most liposomal NMN products do not bother to do. Combined with strong batch-testing transparency and a full clinical dose, this is a credible product from a company that specialises specifically in this problem. The main caveats are the small, company-funded sample size behind the headline 84% figure, and the premium price point relative to standard NMN.

If you are willing to pay more for a brand that has put real (if preliminary) data behind its absorption claims, this is a reasonable choice. Set realistic expectations — individual response varies, and subjective benefits like energy and recovery typically take 4–8 weeks to become noticeable, if they appear at all.

Key Takeaways

500mg of NMN per 2-capsule serving, using a proprietary freeze-dried liposomal encapsulation process
One of the few NMN brands with an actual head-to-head trial against standard NMN and placebo — showing an 84% NAD+ increase after 4 weeks
That trial was small (15 participants total) and company-funded, so treat it as a promising signal rather than definitive proof
Strong batch-level testing transparency via published Certificates of Analysis
Premium-priced relative to standard NMN capsules at the same dose — reasonable if you value the testing and format options Renue offers
