One molecule.
A century of
study.
Methylene blue is one of the most-studied compounds in medicine — used for over a hundred years, and researched today for its role in mitochondrial energy and cellular redox balance.
Our solution is a single, honest formulation: methylthioninium chloride at 1% in purified water. No fillers, no blends, no theatre. Just a precise dose you control by the drop.
The compound
Methylthioninium chloride (methylene blue), 1% aqueous solution.
The form
UV-protective cobalt glass dropper bottles — 30 ml and 100 ml.
The proof
Third-party tested by Eurofins (ISO 17025), heavy metals by ICP-MS.
What people reach for it for
The experience, in their words.
We don’t make medical claims — but our customers are vivid about how they feel. Three themes come up again and again.
01 — Focus
Quieter, longer concentration
Customers describe staying with a task without the mind wandering — a steadier kind of attention through the day.
02 — Energy
Fewer midday dips
A common note: smoother energy and less of the afternoon slump, taken earlier in the day.
03 — Clarity
Less fog, more signal
The word that recurs most is “clarity” — thinking that feels a little cleaner and easier to hold.
Read the research yourself.
We keep a plain-English library of the studies people cite on methylene blue — mitochondria, neuroprotection, ageing, mood. Useful context, openly linked, no spin.
