WHY NOOBLUE DROPS?

Six benefits. Maximum control.

Flexible 0.5 mg increments put you in control while supporting the cellular energy behind focus, memory and everyday performance.

Cellular energy

Supports electron transport and ATP production—the energy cells use to perform.

Sharper focus

Supports brain energy metabolism for clearer, more productive thinking.

Memory support

Supports the cellular energy demands behind learning and recall.

Antioxidant redox support

Reversible redox activity helps manage oxidative stress inside cells.

Flexible dosing

Fine-tune your routine in precise 0.5 mg increments, one drop at a time.

Easy to mix

Add your selected amount to water or juice for a simple liquid routine.

WHAT’S INSIDE

One active. A precision liquid system.

Two essential ingredients and a precision glass dropper create a clean, adjustable liquid system.

01

Methylene Blue USP 1%

The redox-active core supporting mitochondrial energy and cognition.

02

Distilled Water

A clean liquid carrier designed for precise, repeatable measuring.

03

Precision Glass Dropper

A measured delivery system for 0.5 mg adjustments and repeatable dosing.

Formula: Methylene Blue USP 1% · Distilled Water

HOW IT WORKS

Supports the energy behind cognition.

Methylene blue’s reversible redox activity helps move electrons through the cellular environment that produces energy.

01
Accepts electrons

Methylene blue begins the cycle in its oxidized state.

02
Cycles between redox states

The molecule can move between oxidized and reduced forms.

03
Supports electron transport and ATP

The cycle supports the mitochondrial pathways behind cellular energy.

PURITY & TESTING

Testing you can read.

Contract Testing Laboratories of America (CTLA) analyzed the methylene blue ingredient identified as lot 2025022801 in report 135621. The report records an HPLC identity result of “Conforms” and individual results for arsenic, cadmium, mercury and lead.

This is ingredient-level evidence. It does not establish a numerical purity percentage, finished-product potency or certification of every batch. Read the original document alongside its scope and limitations.
