Ingredient face-off
Best NMN Supplements Compared: Which NAD+ Precursor Actually Delivers?
NMN (nicotinamide mononucleotide) is one of the most-marketed longevity ingredients — but the RCT evidence base is thinner than the marketing suggests, and manufacturer purity varies wildly. This head-to-head shows the top-scoring NMN products in the Vyvata catalog on evidence quality (Martens 2018, Yoshino 2021, Mills 2016 hierarchy), ingredient purity, dose disclosure, and independent testing.

Per-product deep dive
#1 Beat Charge - NMN (500 mg ß-Nicotinamide Mononucleotide)55/100 · Standard
500 mg single-ingredient NMN. Yoshino 2021 (JAMA) and Irie 2020 showed NAD+ elevation but clinical benefits remain preliminary; FDA excluded NMN from the supplement definition in 2022, creating regulatory uncertainty. No COA, purity %, or third-party HPLC testing disclosed — critical for NMN given widespread purity issues (ConsumerLab 2023 found many products under-dosed).

#2 NMN 500mg – 99.9% Pure NMN Supplement, Boost NAD+ Levels, Cellular Energy & Healthy Aging Support, 60 Capsules, Third-Party Tested, NSF cGMP, Made in USA53/100 · Standard
500 mg NMN per capsule with 99.9% purity claim and NSF cGMP facility. NMN has emerging PK/PD data (Yoshino 2021) at 250–1000 mg/day. Amazon-style listing and unknown COA weaken confidence, but the dose sits within investigated ranges. Standard.
#3 NMN + Resveratrol Capsules53/100 · Standard
1200 mg NMN + trans-resveratrol combo. Human NMN evidence is emerging (Yoshino 2021 improved insulin sensitivity at 250 mg; Igarashi 2022 safety at 1250 mg), but the description does not split the 1200 mg between NMN and resveratrol, weakening transparency. Neurogan lists third-party lab testing, keeping this out of auto-fail territory but limiting confidence.
#4 NMN+SOD 3-in-150/100 · Standard
Yeast-derived beta-NMN + SOD + pterostilbene stack targets NAD+ pathways. NMN human data are early (Yoshino 2021, 250 mg/d 10 wk raised muscle NAD+ in prediabetic women); SOD oral bioavailability is contested. Price ($258) is high for undisclosed NMN mg and no third-party purity certificate.
#5 NMN+G Rx Advanced Formula - Wizard Sciences45/100 · Rejected
NMN + apigenin + ginsenosides for NAD+ support. Yoshino 2021 pilot (n=25 women) at 250mg NMN showed modest insulin sensitivity improvement in prediabetic postmenopausal women; broader anti-aging claims exceed evidence. NMN, apigenin, and ginsenoside doses are not disclosed at $90.

How the scoring works
Every product is scored on six dimensions — evidence (RCT quality supporting the active ingredients at the label dose), formulation (dose adequacy, bioavailability form, redundancy), manufacturing (third-party testing, GMP, facility audits), safety (adverse-event profile, interactions, dose ceiling), transparency (dose disclosure vs proprietary blends, honest marketing), and sustainability (sourcing, packaging, corporate practice). Tier thresholds: Elite 85+, Verified 70–84, Standard 50–69, Rejected 0–49. Rejected products stay listed with reasons. Full rubric →
