Alive By Science

Overview

Alive By Science no longer exists as an independent brand. If you found this review through an older forum post, a search result referencing “Alive By Nature,” or a legacy supplement database, this page exists specifically to clarify that: the company that created the first sublingual NMN supplement now operates entirely as Renue By Science, reachable at renuebyscience.com. The products are the same. The pricing is the same. The scientific positioning — built on liposomal and sublingual delivery research — is the same. Evaluating Alive By Science separately from Renue By Science in 2026 would be misleading; they are one continuous product line under a different brand name.

The brand’s history is worth understanding for anyone doing due diligence. Founded in 2017 in Jacksonville, FL, the company launched as Alive By Nature, created what it positioned as the first sublingual NMN supplement available commercially, and then rebranded to Alive By Science to more directly signal the research basis of its approach. A subsequent trademark dispute resulted in a forced rebrand to Renue By Science, the current operating identity. This three-step name evolution has fragmented the brand’s reputation across review sites and forums, creating a confusing picture for buyers who encounter references to any of the three names.

The key takeaway: the historical brand is worth knowing because its innovation record is real, but the practical purchase and evaluation target is Renue By Science.

What the evidence shows

The research underpinning the Alive By Science / Renue By Science approach centers on delivery format rather than NMN’s effects in isolation. The company has published and cited clinical research on liposomal delivery mechanisms, arguing that sublingual and liposomal formats increase bioavailability compared to standard oral capsules. Published research from Ohio University has been cited in their marketing to support the bioavailability claim for liposomal NMN.

NMN’s underlying biology — its role as a precursor in NAD+ biosynthesis pathways — is an active area of research. Human clinical trials for NMN remain limited in scale and duration. Animal studies, primarily in rodents, have shown various metabolic and tissue-level effects, but these do not directly translate to proven human outcomes. No supplement product in this category — including those sold under the Alive By Science or Renue By Science brand — has been evaluated by the FDA for any disease treatment or prevention purpose. Claims that NMN “boosts NAD+ levels” as a health outcome or “extends lifespan” are not supported by current human clinical evidence and are not made in this review.

What the brand can legitimately claim is a longer track record than most NMN competitors, a delivery-format differentiation backed by cited research, and a full NAD+ precursor product line (NMN, NR, and NAD+ directly) that gives buyers flexibility. Whether any of these formats produce meaningful real-world wellness differences compared to standard capsule NMN remains unproven in large-scale human trials.

Third-party testing and COA

Renue By Science (the current brand) lists triple lab-tested products with COAs as a key feature. We have not independently verified COA documentation — our sample source for this review is listed as not-tested. Buyers should request the current COA directly from Renue By Science’s website for any product under consideration. A meaningful COA should specify: the testing laboratory, batch number, the NMN or NR purity assay methodology, and contaminant screening results. This is standard practice for a reputable NMN supplier and should not require effort to obtain.

Formulation and dosing

Alive By Science’s product catalog — now sold under Renue By Science — includes:

• Sublingual NMN: the format that differentiated the original brand; dissolves under the tongue to bypass first-pass gastrointestinal metabolism
• Liposomal NMN: encapsulated in liposomes to support absorption
• NR (nicotinamide riboside): an alternative NAD+ precursor for buyers who prefer NR over NMN
• NAD+ direct: for buyers who want to supplement the molecule directly rather than via a precursor

Specific doses, prices, and current product availability should be verified at renuebyscience.com, as the product line has evolved through the rebrand sequence and our data reflects the brand’s positioning rather than a live product specification. The company is vegan-friendly and has positioned its manufacturing around US-based production standards.

Cost breakdown

Because Alive By Science is now Renue By Science, the pricing landscape is the same as evaluating Renue. Representative current market positioning:

Brand	Format	Approx. monthly cost
Renue by Science (formerly Alive By Science)	Liposomal NMN 500mg	~$45–90/month
DoNotAge	NMN 500mg standard	~$20/month
ProHealth	NMN 500mg standard	~$45–60/month (subscribe)
Tru Niagen	NR 300mg standard	~$45/month
Wonderfeel Youngr	NMN 900mg multi-ingredient	~$73–88/month

Renue by Science sits in the mid-to-upper range of the category. Its liposomal and sublingual premium is reflected in price; buyers who want the cheapest cost-per-gram of NMN will find better value elsewhere.

Where it fits

• Evaluate Renue By Science if you specifically value delivery-format differentiation (sublingual or liposomal NMN/NR), you want a brand with a longer track record and published bioavailability research, and you want access to both NMN and NR under the same supplier.
• Consider alternatives if you want the lowest cost-per-gram of NMN (DoNotAge), you want a single well-known NR brand with the longest human trial record (Tru Niagen), or you want a physician-curated high-dose NMN stack (Wonderfeel). Buyers who want to rely on the largest consumer review base should also compare Tru Niagen, which has more established retail presence.
• Do not evaluate “Alive By Science” as a distinct brand — the product line, pricing, and company are one and the same as Renue By Science. Separate comparisons between the two are not meaningful.

Verdict

The conditional verdict here reflects a structural reality, not a product quality judgment. Alive By Science is not an independent purchasing option in 2026 — it is a historical brand name for what is now Renue By Science. The research credentials behind the brand are real: first-mover in sublingual NMN, published bioavailability research, a full NAD+ precursor product line, and a reasonably long track record for a supplement category that barely existed before 2018. The limitations are also real: the evidence for NMN producing meaningful longevity outcomes in humans is early and unproven, the brand-name evolution has fragmented consumer trust across review sites, and the forced rebrand history introduces some reputational complexity worth knowing.

For buyers who landed here because they saw a positive reference to “Alive By Science” somewhere: the current brand is Renue By Science, the products are the same, and that is where to direct your due diligence.
