Renue By Science review

Renue By Science does the two things that actually matter for a supplement retailer: it posts third-party batch certificates, and it gives you real choice of format and precursor. That is a meaningful answer to the biggest practical risk with NMN, which is that measured purity varies between products. What it is not is evidence — the delivery-format claims are marketing ahead of human data, and no oral precursor has been shown to slow aging.

Renue By Science is a longevity-supplement brand, not a telehealth service. Ordinary retail purchases do not include prescribing or diagnosis. Its range covers both NAD⁺ precursors, NMN and nicotinamide riboside, across an unusually wide set of formats: liposomal capsules, sublingual fast-dissolve tablets, sublingual powders and gel, and an NAD⁺ nasal spray, plus a liposomal blend that combines NAD⁺, NMN, NR and trigonelline.

The current catalog also includes enteric capsules; compare the exact formulation rather than assuming every product uses the same delivery format. It publishes third-party lab certificates for finished-product batches, listed by batch number.

Direct-to-consumer retail. Standard purchases do not include a health-history review, prescribing or ongoing clinical care. You choose the product and format; questions about dosing, interactions and suitability belong with your own physician.

An optional HSA/FSA payment route uses an independent Truemed clinical assessment. Qualification is individual and not guaranteed; this payment assessment does not make an ordinary supplement purchase a clinician-managed NAD⁺ treatment service.

Compare the exact precursor, pack size and format. NAD+ Complete lists $84.95 one-time. Its quantity-one subscription selection shows $76.46 per delivery, defaulting to every 60 days, with 30-, 45-, 90-, 120- and 180-day options. These are product charges, not monthly care fees. The subscription requires Shop Pay and advertises cancel, skip or change frequency anytime; confirm the management method and processing cutoff. Other products may differ.

Shipping terms list free US standard shipping over $50, while the selected subscription widget says over $45 and a gift page says over $100. Confirm the threshold at checkout. Orders after 2 PM EST process the next business day; there is no weekend fulfillment, and original shipping fees are nonrefundable.

The dedicated refund policy offers support-assisted refund or replacement within 60 days; the gift page instead advertises 30 days. Confirm the period and opened-product eligibility for your offer before paying.

None — this is a dietary supplement, not a medication, and no prescription is involved. Posting a third-party certificate of analysis per batch is a genuine differentiator, because independent testing has found real variation in measured NMN content between products; a certificate tied to the batch number on your bottle helps you trace the testing reported for that batch. Check which tests a given certificate covers: Renue's posted reports mix potency results with heavy-metal and microbiology screens, and not every report includes potency. On the evidence, be clear-eyed about two separate things. First, the compounds: oral NR and NMN do reliably raise blood NAD⁺ in controlled human studies, and that half is well established — but the human outcome data stops at small, surrogate-endpoint studies, and no trial shows either compound extends healthspan, prevents disease or slows aging. Second, the format: the liposomal and sublingual delivery story is a bioavailability argument, and the trials that raised NAD⁺ used conventional oral dosing. Better absorption on paper has not been shown to translate into a better clinical result. On regulation, NMN's US status has been genuinely contested — the FDA concluded in 2022 that NMN was excluded from the dietary-supplement definition, which disrupted its sale, and in a response dated September 29, 2025 the agency reversed that position, concluding NMN had been marketed as a supplement before it was authorized for investigation as a new drug. Because that history has moved once already, confirm the current status and availability where you live rather than assuming it is settled.
