NAD+ & NMN Cellular Vitality Organic Formula with Resveratrol

Six-dimension breakdown

Why this scored 48/100

VeggieVerve/Livingston Naturals NAD+/NMN with resveratrol formulation targets the fastest-growing supplement segment (longevity_cellular). The ingredient category has real emerging RCT evidence: NMN at 250-500 mg/day (Yoshino 2021 crossover, Yamane 2023) has demonstrated modest increases in serum NAD+ levels, and Tru Niagen's nicotinamide riboside has larger trials (Martens 2018, Airhart 2017) with similar findings. Resveratrol has extensive but mostly-underwhelming trials at 100-500 mg/day. The problem with this specific SKU is transparency — the reviewed product copy references NMN and resveratrol but does not disclose per-serving milligram content for either, meaning a reviewer cannot verify whether the formula delivers doses matching the Yoshino/Yamane trial ranges or subclinical amounts. NAD+ precursor products in general have been shown by third-party testing (ConsumerLab 2022) to sometimes contain far less NMN than labeled — some products tested at 30-50% of claimed content. Without disclosed doses and without third-party lot testing, autofail on proprietary_blend_hides_dose applies. The category is legitimate; the specific SKU disclosure is insufficient.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
