Stronglife edges ahead with a slightly higher overall score (64 vs 62) and notably stronger effectiveness rating, plus its 600mg NMN and trans-resveratrol formula offers more active ingredients per serving. Goodvita suits buyers on a tighter budget who prioritise UK manufacturing and prefer a lower dose, though its poorer value score (54 vs 73) makes the £7 saving feel marginal.

- ✓Filler-free, clean capsule formula with no reported adverse effects
- ✓Objective NAD⁺ blood-test evidence from one reviewer showing measurable increase after 3 months
Cons

What does the data say about High Strength NMN Supp... vs NMNH (NMN Alternative) 500mg?
Both products target the same NAD+ precursor pathway, but they differ in a meaningful way: Stronglife uses NMN (nicotinamide mononucleotide) paired with trans-resveratrol at 600mg each per serving, while Goodvita uses NMNH — a reduced form of NMN that some researchers suggest is absorbed more efficiently, though the clinical evidence remains limited. Stronglife's combination formula is the more aggressive approach, stacking two compounds that theoretically work synergistically on NAD+ production and sirtuin activation. Goodvita keeps it simpler with a single active at 500mg. Neither product carries third-party testing certification, which is a genuine concern in a supplement category that's prone to label inaccuracies.
If you're in your 40s or 50s, reasonably active, and want the higher-dose dual-compound approach, Stronglife at £24.99 makes sense — the 600mg NMN plus trans-resveratrol combination is hard to match at that price, and reviewers note it's clean with no fillers. That said, three people reported no benefit whatsoever, and with no third-party verification, you're taking that on faith. Goodvita at £17.99 scores slightly lower overall (62 versus 64) but is UK-manufactured, well-tolerated across all reviewers, and particularly praised by users over 50 for energy and cognitive clarity. Its value score of 54 is noticeably weaker, which suggests the pricing isn't especially competitive for what you're getting.
Practically speaking, both come in capsule form and neither discloses specific pill sizes or allergen information prominently. Goodvita's UK manufacturing is a reassuring practical detail — shorter supply chains and easier recourse if something's wrong. Neither is recommended if certification matters to you, such as for professional sport or strict vegan verification, as both carry unverified claims on those fronts.
Stronglife's NMN + Resveratrol delivers 600mg of each active per serving in vegan-friendly, filler-free capsules, positioned as a high-dose cellular longevity stack for the UK market.
