Life Extension Low-Dose Methylene Blue
Pharmaceutical-grade 50mg capsules for micro-dose nootropic protocols
Life Extension offers one of the few commercial pharmaceutical-grade methylene blue products designed for low-dose use. Each 50mg capsule can be split for 0.5–4mg micro-dose protocols. Critical: verify you are NOT on SSRIs/SNRIs before use — methylene blue has MAOI activity.
Typical price: $22 – $30 USD / 60 capsules

How It Works
At low doses, methylene blue acts as an alternative electron carrier in mitochondrial Complex IV, potentially maintaining ATP synthesis when native electron transport is impaired by aging or oxidative stress.
Mitochondrial Electron Carrier
Accepts electrons in the electron transport chain, supporting ATP production in aging mitochondria.
Pharmaceutical Grade
USP-grade methylene blue — not aquarium or industrial grade with toxic contaminants.
Micro-Dose Protocol
50mg capsules allow precise subdivision for 0.5–4mg daily nootropic doses.
What You'll Experience
Starting
Week 1Begin at 0.5mg (fraction of capsule). Blue tongue and urine are normal. Monitor for headaches.
Titration

Cycle Off
Week 4–8Discontinue after 4–8 weeks. No long-term daily safety data at nootropic doses.
Benefits

Risks & Considerations
Serotonin Syndrome
high riskCONTRAINDICATED with SSRIs, SNRIs, tramadol. Can be fatal. Check all medications first.
G6PD Deficiency

Community Reviews
Synthesized consensus from Reddit, forums, and expert sources.
Respected for pharma-grade sourcing but 50mg capsules are awkward for micro-dosing. 'Get a milligram scale and empty capsules for proper low-dose protocol.'
