LEUCO is a 1% USP-grade methylene blue solution – clean, pure, and purposefully unadorned.

It’s not leucomethylene blue yet.
But that’s the point.

Once inside the body, methylene blue is reduced to its active, colorless form: leucomethylene blue – a potent mitochondrial ally and electron donor. That transformation is where the magic happens. It’s subtle, silent, and powerful. Just like LEUCO.

This isn’t a stimulant. It doesn’t mask fatigue or trick the mind. It works at the level of charge – supporting redox balance, oxygen efficiency, memory, and resilience in the face of chronic environmental stressors.

LEUCO is for those who understand that health isn’t just about what you take – it’s about what your body can do with it.
