Why Purity Matters
Industrial-grade methylene blue is manufactured for laboratory staining and textile dyeing. It commonly contains heavy metals including arsenic (up to 40 ppm), lead, mercury, and cadmium. At supplement dosing of 5-30mg daily over months, heavy metal exposure becomes significant.
USP-grade MB is purified to 99%+ with verified absence of contaminants. The price difference between industrial and USP-grade is small compared to the long-term health cost of heavy metal accumulation.
Why Format Matters
Liquid Drops
Flexible dosing but stains teeth, tongue, and surfaces. 60-70% bioavailability.
Troches (Sublingual)
Faster absorption (~75% bioavailability) but significant oral staining.
Capsules
Zero staining, consistent dosing, ~72% bioavailability. Best UX for daily use.
Bioavailability difference between formats is minimal (60-75%), but user experience differs significantly. Staining from liquids and troches is a common complaint on Reddit and review sites. Once you have chosen a format, see our dosing guide for how to get started.

Frequently Asked Questions
Which methylene blue brand is best?+
For USP-grade purity, zero staining, and biomarker compatibility, Methylene Blue Ultra leads. Troscriptions is a credible alternative if you prefer sublingual format and don't mind staining. Avoid industrial-grade Amazon options.
Is USP-grade worth the price?+
Yes. The price difference is typically $0.05-0.15 per mg. For a daily 10mg dose, that's $1.50/month extra for verified purity and heavy metal testing. The long-term health cost of heavy metal accumulation far exceeds this.
Why does Troscriptions stain?+
Troscriptions uses a sublingual troche (lozenge) format that dissolves in the mouth. The blue dye deposits directly on oral tissue, staining tongue and teeth. This is cosmetic and temporary but a common user complaint.
Are Amazon methylene blue supplements safe?+
Most are not. Generic Amazon sellers typically offer industrial-grade MB intended for aquariums or laboratories. Without third-party testing or COA, there's no way to verify purity or heavy metal content. Some samples have tested positive for concerning levels of arsenic and lead.
What should I look for in a COA?+
A valid Certificate of Analysis should include: (1) Purity percentage (>99% for USP), (2) Heavy metal testing results (As, Pb, Hg, Cd), (3) Third-party lab name and accreditation, (4) Batch/lot number matching your product, (5) Test date within 2 years.
