The Biohacker's
90-Day MB Protocol
Science-backed methylene blue dosing for cognitive support, mitochondrial function, and biomarker tracking.
1. Why Methylene Blue for Biohackers
Methylene blue is the original mitochondrial optimizer. First synthesized in 1876, it has over 150 years of documented use in medicine and research. Unlike most supplements, MB has a clear mechanism of action: it acts as an alternative electron carrier in the mitochondrial electron transport chain, bypassing complex I and III dysfunction to restore ATP production.
For biohackers, this means supporting cellular energy, cognitive function, and exercise recovery. Published research shows MB crosses the blood-brain barrier within 1 hour, accumulates in metabolically active tissues, and supports oxygen utilization at the mitochondrial level. The effects are dose-dependent and follow a biphasic curve — low doses stimulate, high doses inhibit.
This protocol uses a flat oral schedule — 5mg to start, 10mg as the target, 20mg as a routine ceiling — rather than a per-kilogram calculation. Every human oral study of methylene blue used a fixed dose, not a mg/kg dose; the mg/kg figures that circulate in dosing guides are intravenous clinical doses or rodent injection doses, and neither converts into an oral supplement. The goal: maximum benefit, minimal downside, with biomarkers to track the process.
2. The 3-Phase Protocol
Phase 1: Titration
Weeks 1-2
Start low to assess tolerance and identify any sensitivities. Begin with 5mg/day (one capsule) taken in the morning with food. Monitor for blue-green urine (normal) and any GI sensitivity.
- Week 1: 5mg/day, morning with breakfast
- Week 2: 5mg/day, continue if tolerated well
- Signal to watch: Energy boost within 1-2 hours post-dose
- Red flag: Persistent nausea or headache — reduce dose or pause
Phase 2: Maintenance
Weeks 3-8
Move to 10mg/day — the target dose, not a step toward something higher. This is a flat schedule regardless of body weight, and 10mg is also the serving size most capsules on the market are sold at. Split dosing (morning + noon) may support sustained cognitive effects.
- Week 3: Increase to 10mg/day
- Week 4-8: Hold at 10mg/day — this is the destination, not a waypoint
- Timing: Morning dose, or split AM/noon for extended effects
- Avoid: Evening dosing — MB can affect sleep in some users
Phase 3: Cycle or Maintain
Weeks 9-12+
After 8 weeks of consistent use, choose your path: continue at maintenance dose for ongoing benefits, or cycle off for 2-4 weeks to assess baseline. Many biohackers prefer 8-weeks-on, 2-weeks-off cycling.
- Option A: Continue maintenance indefinitely
- Option B: 2-week washout, then restart Phase 2
- Option C: Reduce to 5mg/day as maintenance microdose
- Retest: Ideal time for follow-up biomarker testing
3. The Flat Dosing Schedule
Oral methylene blue is dosed as a flat daily amount, not as a calculation against body weight. Every human oral study of methylene blue used a fixed dose — the mg/kg figures that circulate in dosing guides are intravenous clinical doses or rodent injection doses, and neither converts into an oral supplement dose. Use the same schedule regardless of what you weigh.
| Phase | Daily Dose | Hold Before Changing | What It Is For |
|---|---|---|---|
| Start | 5 mg | At least 7 days | Establishing tolerance before anything else changes |
| Target | 10 mg | 14 days, then stop titrating | The destination — also the most common capsule size sold |
| Ceiling | 20 mg | Not a scheduled step | Routine upper bound — no exceptions for bodyweight or experience |
* No published randomized controlled trial has tested chronic daily oral methylene blue in healthy adults for cognitive or mitochondrial endpoints — this schedule is an extrapolation from single-dose human studies and market serving sizes, not a validated protocol.
4. Synergistic Stacking Protocols
Methylene blue pairs well with other mitochondrial and nootropic compounds. These evidence-based stacks amplify specific outcomes.
Photobiomodulation Stack (Red Light + MB)
Red/near-infrared light (630-850nm) activates cytochrome c oxidase. MB enhances this effect by improving electron transport. Use within 30 min of dosing.
NAD+ Precursor Stack (NMN/NR + MB)
NAD+ is required for mitochondrial function. Combining with MB supports both the substrate (NAD+) and the electron transport efficiency.
Neurogenesis Stack (Lion's Mane + MB)
Lion's Mane promotes NGF and BDNF. Combined with MB's neuroprotective effects, this stack targets both neuroplasticity and mitochondrial brain energy.
Athletic Performance Stack (Creatine + MB)
Creatine buffers ATP in high-demand tissues. MB supports ATP synthesis efficiency. Together, they support both supply and demand sides of cellular energy.
5. What to Track
The difference between biohacking and guessing is measurement. Track these markers to quantify your response to the protocol.
Subjective Markers (Daily)
- Energy: Rate 1-10 at same time daily (e.g., 2pm)
- Mental clarity: Focus duration, brain fog episodes
- Sleep quality: Time to fall asleep, wake-ups, restedness
- Exercise recovery: DOMS duration, next-day readiness
- Mood: Baseline anxiety, motivation levels
Objective Biomarkers (Periodic)
- Epigenetic age: TruDiagnostic TruAge (baseline + 90 days)
- HRV: Daily via Oura, Whoop, or Apple Watch
- Glucose: CGM data or fasting glucose (monthly)
- Inflammatory markers: hs-CRP, IL-6 (every 3 months)
- Cognitive tests: Cambridge Brain Sciences or similar
6. Safety Checklist
Do NOT Use Methylene Blue If:
- XYou take SSRIs, SNRIs, or MAOIs (serotonin syndrome risk)
- XYou have G6PD deficiency (hemolytic anemia risk)
- XYou are pregnant or breastfeeding
- XYou have severe renal impairment
- XYou take serotonergic supplements (5-HTP, St. John's Wort)
Pre-Protocol Checklist:
- ✓Confirm no SSRI/SNRI/MAOI use (including recent discontinuation)
- ✓Screen for G6PD deficiency if ancestry risk (Mediterranean, African, Asian)
- ✓Inform your healthcare provider about supplementation plans
- ✓Use only USP-grade (USP) methylene blue
- ✓Start with lowest dose (5mg) to assess individual tolerance
