Our Verdict: Althevity NAD+ Longevity or WeightWorld Trans Resveratrol?

Althevity edges ahead with a 75/100 vs WeightWorld's 73/100, thanks to a more sophisticated stack including patented ErgoX, methylated B-vitamins, and multiple longevity actives beyond resveratrol. WeightWorld suits budget-conscious buyers who want a simple, clean two-ingredient formula at £26.79 for four months — particularly those who already take NR or other actives separately.

Score Summary

Althevity NAD+ Longevity scores 75.0/100 vs WeightWorld Trans Resveratrol at 73.0/100. Althevity NAD+ Longevity wins on effectiveness, ingredient quality, side effects. WeightWorld Trans Resveratrol is stronger on value for money and certifications.

Althevity NAD+ Longevity vs WeightWorld Trans Resveratrol: What Does the Data Say?

Althevity's NAD+ formula (£34.99, 75/100) takes a kitchen-sink approach to longevity: NR, trans-resveratrol, spermidine, PQQ, fisetin, quercetin, and patented ergothioneine — all in one capsule. WeightWorld's offering (£26.79, 73/100) is deliberately leaner, pairing trans-resveratrol with 50mg quercetin and nothing else. The Althevity formula uses methylated B-vitamins and bisglycinate minerals, which suggests some care around absorption, though without disclosed individual dosages it's impossible to know whether NR hits the 300mg+ levels used in clinical studies. WeightWorld's quercetin is standardised to 98% purity from Sophora japonica, but at 50mg it sits well below the 500–1000mg therapeutic range seen in research.

If you're already curious about the broader longevity stack — NR, spermidine, PQQ — and want to consolidate several supplements into one, Althevity makes sense despite costing more per month and offering only 30 days' supply. If you simply want resveratrol and quercetin as a daily antioxidant pair without committing to a premium price, WeightWorld's 4-month supply at £26.79 scores 82/100 on value and is the more practical everyday option.

Neither product carries third-party certification, so neither is suitable for competitive athletes subject to testing. Both are vegan capsules, and WeightWorld specifically removes magnesium stearate, which some people prefer to avoid. Pill load matters too: Althevity requires two capsules daily versus WeightWorld's one.

NAD+ Longevity Supplement – 14 i...

Pros

  • Broad-spectrum NAD+ and longevity stack — NR, resveratrol, spermidine, PQQ, fisetin, quercetin, and patented ErgoX ergothioneine address multiple ageing pathways simultaneously
  • Consistently reported energy boost and improved mental clarity across the majority of reviewers, with effects noticed within days to weeks
  • Bioavailability-conscious formulation: bisglycinate mineral forms, methylated B-vitamins (Biofolate & Methylcobalamin), and black pepper extract for absorption
  • Vegan capsules, free from gluten, soy, dairy, egg, gelatin, and peanut — suitable for clean-label consumers

Cons

  • 60 capsules is only a 30-day supply at the recommended two-per-day dose — easy to underestimate at purchase
  • Individual ingredient dosages are not clearly disclosed on the listing, making it difficult to verify whether NR and other actives reach clinically studied thresholds
  • Third-party testing status is unconfirmed; product specs indicate untested, despite some reviewers referencing cGMP manufacturing (which is not equivalent to independent testing)
  • Price history is inconsistent — the product launched at £49 before dropping to £19.99, raising questions about long-term pricing and brand maturity

Best For

Adults over 40 focused on healthy ageing and longevity Gym-goers and active individuals seeking cellular energy support Those already taking NR or quercetin separately who want a consolidated stack Consumers who prioritise clean, allergen-free, vegan formulations Biohackers looking for a broad-spectrum entry-level longevity supplement

Trans Resveratrol with Quercetin...

Pros

  • Competitive value — 120 capsules (4 months) at a fraction of premium longevity brand prices
  • High-purity quercetin (98% standardised from Sophora japonica) with well-regarded bioavailability synergy
  • Clean formulation: no magnesium stearate, gluten-free, non-GMO, GMP-manufactured
  • Consistently positive user-reported outcomes: energy, skin texture, and general vitality

Cons

  • No third-party testing (e.g. Informed Sport, NSF) — label claims unverified independently
  • Quercetin dose (50mg) is below the 500–1000mg range used in most clinical studies
  • Resveratrol bioavailability is inherently variable without fat co-ingestion or adjuvants like piperine
  • Vegan status inconsistently stated — product description claims vegan-friendly but spec data flags otherwise; capsule shell material unclear

Best For

Adults over 40 seeking longevity and antioxidant support Users pairing resveratrol with NMN or NR for sirtuin pathway protocols Budget-conscious shoppers comparing against premium subscription brands Those wanting a clean, additive-free daily supplement with minimal taste
