Lunakai USP Methylene Blue Capsules
Pharmaceutical-grade 10mg capsules on Amazon — Life Extension is DTC-only
Life Extension's 50mg methylene blue is not sold on Amazon. Lunakai's USP-grade capsules (10mg each, 60 count) are a verified Amazon listing with third-party testing and Prime shipping. Label dose is above biohacker micro-dose protocols — subdivide carefully. Same MAOI/SSRI contraindications apply.
Typical price: $20 – $28 USD / 60 capsules
US Amazon listing — verify the live product page before buying.
How It Works
Same mechanism as other pharmaceutical-grade methylene blue: alternative electron carrier in mitochondrial Complex IV. Dose on the label is often above biohacker micro-dose ranges — subdivide carefully.
USP Pharmaceutical Grade
Capsule form avoids liquid staining; verify third-party purity claims before use.
Mitochondrial Electron Carrier
Low-dose methylene blue supports Complex IV electron transfer in aging mitochondria.
Amazon Fulfillment
Prime-eligible alternative when Life Extension DTC shipping is slow or unavailable.
