Evidence Anchor
BioHarmony 6.3/10
NMN is a 6.3 / 10 fit for older or metabolically strained adults who want an NAD+ precursor trial with measured endpoints, not a reliable anti-aging shortcut for already healthy adults. The cleanest evidence anchors are [Zhang 2024](https://www.tandfonline.com/doi/abs/10.1080/10408398.2024.2387324), which found NAD levels rose while broad glucose and lipid outcomes stayed limited, and [Yoshino 2021](https://pmc.ncbi.nlm.nih.gov/articles/PMC8550608/), which reported a 25% muscle insulin-sensitivity gain in prediabetic postmenopausal women. [Igarashi 2022](https://pmc.ncbi.nlm.nih.gov/articles/PMC9158788/) adds useful context: found NAD+ elevation and selected physical-function changes in older men. The practical gap is the same one that shows up across the report: mechanism and early outcomes are more convincing than broad real-world certainty. In practice, NMN belongs after the basics, works best when the target is specific, and deserves tracking around benefits, side effects, interactions, and cost before it becomes a standing protocol. ✅ Best for: Adults over 40 with likely NAD+ decline, especially those with insulin resistance, higher BMI, declining physical function, low training volume, or poor lifestyle NAD+ inputs. NMN makes the most sense after the foundations are in place: resistance training, aerobic work, sleep regularity, protein adequacy, metabolic health, sauna or heat, and fasting rhythm. It is also reasonable for self-quantifiers willing to track fasting insulin, HbA1c, blood pressure, subjective energy, and training capacity over an 8-12 week trial. ❌ Avoid if: You have active cancer, are on PARP inhibitor therapy, are pregnant, breastfeeding, under 18, or have complex oncology history without clinician oversight. Avoid NMN if you need guideline-backed diabetes, hypertension, sarcopenia, or cardiovascular care, because no major medical society recommends NMN as treatment. Also skip it if $60-100/month would displace higher-confidence basics, if you expect same-week energy transformation, or if your lifestyle already gives you strong NAD+ support and you are chasing marginal gains.

My score and my verdict: one signal of three, never the whole answer.
Momentum
Signals begin with Edition 2
Direction needs two weekly snapshots to compare, so the arrows stay off until the next edition. Attention tracking is already running.
Momentum = how fast attention is rising across search, Reddit, PubMed, podcasts, and curated industry newsletters this week; it can flag an item as Overhyped/Fading, but it never overrides the evidence behind Proven. How momentum works.
