Evidence Anchor
BioHarmony 6.1/10
Methylene Blue is a 6.1 / 10 fit for advanced users who understand that methylene blue is a drug-like redox compound, not a casual blue nootropic, because the strongest evidence is medical, while healthy-user cognition claims remain much thinner. [Rothenberg 2025](https://pubmed.ncbi.nlm.nih.gov/40062661/) gives the strongest anchor, while [Rodriguez 2016](https://pubmed.ncbi.nlm.nih.gov/27351678/) adds useful context without closing the case. The honest gap is simple: low-dose consumer protocols do not have the same backing as methemoglobinemia, shock, or procedure-specific uses. That puts Methylene Blue in the tracked-experiment category, not the automatic-staple category. In practice, Methylene Blue makes the most sense when you monitor dose, medication interactions, mood, sleep, cognition tasks, oxygenation context, and adverse effects and avoid treating Methylene Blue like a broad brain-energy upgrade. ✅ Best for: Adults with suspected mitochondrial dysfunction, chronic fatigue patterns, post-viral fatigue, or metabolic dysfunction who are not taking serotonergic drugs and can source pharmaceutical-grade methylene blue. Cognitively demanding knowledge workers who want an occasional 0.5-5 mg acute mental-clarity tool. Biohackers pairing low-dose methylene blue with red light therapy, while admitting the stack is not proven by large RCTs. Adults over 50 exploring mitochondrial support alongside creatine or NAD+ precursors. Medical use belongs to clinicians: acquired methemoglobinemia, select shock contexts, and procedure-specific local analgesia. ❌ Avoid if: You take SSRIs, SNRIs, MAOIs, serotonergic opioids, tramadol, dextromethorphan, linezolid, high-dose 5-HTP, or other serotonergic agents without clinician guidance. Avoid methylene blue with known or possible G6PD deficiency unless tested and cleared, especially with Mediterranean, African, Middle Eastern, or Southeast Asian ancestry. Avoid during pregnancy or planned pregnancy, severe renal impairment, phenothiazine hypersensitivity, and before surgery unless the care team knows. Also avoid aquarium-grade, dye-grade, or generic marketplace methylene blue. Source quality is not a minor detail here.

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.
