Time Labs Methylene Blue 120 Count Review 2026: Misleading Claims
Skip this one. — Misleading
-
"25mg USP grade per capsule at $0.17/dose"
Pharmaceutical-grade purity confirmed by USP label. Price is fair — no markup exploitation on this product.
-
"Sold as a dietary supplement"
Methylene blue is an FDA-approved drug (ProvayBlue). Selling it as a supplement is a regulatory gray zone the FDA has not formally cleared.
-
"Oral methylene blue as a health supplement"
Every clinical trial showing methylene blue benefits used IV infusion or local injection — not oral capsules. No oral supplement RCT exists.

"Safe to take with medications"
Methylene blue combined with SSRIs or SNRIs causes serotonin syndrome — a potentially fatal drug interaction documented in FDA safety communications.
FDA Drug Safety Communication: methylene blue and serotonergic drugs, 2011
Consumer advice
Do NOT take this product if you are on any antidepressant (SSRIs like Prozac/Zoloft, SNRIs like Effexor, or MAOIs) — the combination can cause serotonin syndrome, a potentially fatal condition. Before purchasing, consult your doctor or pharmacist about all your current medications. Be aware that methylene blue is an FDA-approved drug, not a traditional dietary supplement — its sale in this form is legally ambiguous. The product's label appropriately warns about serotonin-affecting medications, but this warning may be easy to overlook. If you are interested in methylene blue for a specific medical condition, discuss it with a physician who can prescribe it in a controlled, monitored setting.
