Your complete methylene blue dosage guide
This dosage guide is designed around our 5 mg pharmaceutical-grade methylene blue capsule – a clean, reliable, wellness-level dose that’s strong enough to feel, gentle enough for beginners, and easy to scale when your body or your day requires more.
Everything here applies to low-dose wellness use only. This is not medical dosing. We’re talking about cognitive support, clarity, mood stability, and mitochondrial efficiency – not hospital protocols.
Why we use 5 mg as the base dose
A 5 mg capsule is the most practical starting point for most people:
- It’s a minimally active but genuinely effective dose.
- It allows your system to adapt gradually.
- It minimizes the risk of overstimulation.
- It scales cleanly: 5 mg → 10 mg → 15 mg.
Most beginners feel subtle improvements at 5 mg – cleaner thinking, smoother emotional state, reduced fog. If your body wants more “fuel,” you simply take a second capsule.
Quick-start overview for our capsules
| User Level | Capsule Dose | Why This Dose |
|---|---|---|
| Beginner | 5 mg (1 capsule) | Allows your mitochondria to adjust without overshooting. |
| Intermediate | 10 mg (2 capsules) | Stronger cognitive and energy support; still gentle. |
| Advanced | 15 mg (3 capsules) | For high-load days when you need more sustained clarity. |
Start low. Build slowly. Your mitochondria respond best to consistent, manageable support, not big jumps.
Understanding mg/kg vs mg/day
A lot of guides use mg per kg. That’s helpful for liquids, but capsules make life easier. Our 5 mg capsule fits into the standard wellness range without math:
- 5 mg – ideal starter
- 10 mg – normal workday support
- 15 mg – high cognitive or physical demand
If you prefer a weight-based rule: 0.25–1 mg/kg usually aligns with 5–15 mg per day for most adults.
How to increase your dose safely
The best approach is gradual. Here’s a simple ramp that works well for most:
- Days 1–3: 5 mg per day.
- Days 4–6: 10 mg per day (2 capsules) if feeling good.
- Day 7+: 15 mg only if you genuinely need more output.
If you ever feel too “activated,” overstimulated, or mentally “tight,” drop back to 5 mg for several days. Your system may simply be receiving more support than it needs.
When to take your dose
Most people feel best when taking methylene blue:
- in the morning – best match for your natural energy rhythm,
- or midday – if stacking with work sessions, study blocks, or movement.
Evening use isn’t recommended – not because it’s unsafe, but because improved cellular energy can make your brain feel a bit too “on” at night.
With or without food
Both work fine:
- With food – gentler for sensitive stomachs.
- Empty stomach – slightly quicker onset.
How long until you feel the effect?
- 1–2 hours: mental clarity, lightness, smoother thoughts.
- 3–7 days: more stable energy and mood balance.
- 2–4 weeks: deeper cellular and skin-level benefits.
Methylene blue works like tuning the engine, not flooring the gas pedal.
How to cycle (5-on / 2-off)
The cleanest and most widely used pattern is:
- 5 days on
- 2 days off
This keeps your system responsive while preventing unnecessary buildup. You can use other rhythms, but 5-on / 2-off tends to deliver the most consistent long-term results.
Signs your dose is optimal
- Your mind feels clear but not edgy.
- Your energy is stable across the day.
- You can focus without forcing it.
- You feel emotionally even and grounded.
Signs your dose is too high
- slight overstimulation,
- restlessness,
- tight or pressured thinking,
- mild anxiety,
- sleep disruption if taken late.
If you feel any of this, reduce to 5 mg for a few days. Your system will usually settle quickly.
Common dosing mistakes to avoid
- Starting at 10–15 mg before trying 5 mg.
- Assuming “more = better.”
- Taking it too late in the day.
- Using liquid without knowing mg per drop.
- Using aquarium-grade products.
Hydration matters
Methylene blue is cleared through the kidneys, so hydration helps minimize concentrated staining and supports smooth elimination. A glass of water with your dose is perfect.
About urine color (don’t worry)
A green or blue haze in urine is completely normal – it simply means the molecule is being processed and excreted.
How to avoid staining
- Take capsules with a full glass of water.
- Rinse mouth if a capsule ever opens (rare).
- Store the bottle upright.
Travel dosing tips
- Capsules are travel-friendly – no liquid issues.
- Time zone change? Just take your dose at the new “morning.”
- Store away from heat and direct sunlight.
Stacking tips (wellness context)
- Vitamin C: pairs extremely well – supports redox cycling.
- Red light therapy: synergistic for mitochondrial support.
- Caffeine: fine together, but start low.
- Electrolytes: great on high-output days.
Who should not take methylene blue without professional guidance
Avoid or speak with a clinician first if you’re using:
- SSRIs
- SNRIs
- MAOIs
- Wellbutrin
- ADHD medications
- Parkinson’s medications
- Or have G6PD deficiency

TL;DR
- 5 mg is the ideal starting point.
- 10 mg is standard for most workdays.
- 15 mg is for high-output days only.
- 5-on / 2-off is the cleanest cycling method.
- If you feel overstimulated, drop back to 5 mg.
- Use only human-grade products – never aquarium MB.
