ONE GUMMY. NO FUSS.
Brain power, made simple.
A precisely dosed methylene blue gummy built to support mitochondrial energy and focus—without drops, measuring or the blue-mouth mess.
Optimized leucomethylene blue
A specialized form of methylene blue that begins in its reduced, electron-loaded leuco state.
No blue-mouth mess
A clean chewable routine without drops, measuring or staining.
Wild Blueberry, zero sugar
Soft pectin texture with a bright, juicy finish.
WHAT’S INSIDE
Two actives. One optimized gummy.
10 mg of USP-grade methylene blue pairs with 25 mg of vitamin C to shift most of the active into colorless, electron-loaded leucomethylene blue before you take it.
THE ACTIVE FORMULA
10 mg Methylene Blue USP
The redox-active core supporting mitochondrial energy and cognition.
25 mg Vitamin C
The built-in reducing agent that donates electrons inside the gummy.
Optimized leucomethylene blue
Reduced. Electron-loaded. Colorless by chemistry.

WHAT IT SUPPORTS
Power your mind at the cellular level.
Methylene blue supports the mitochondria that fuel cognition—helping promote cellular energy, focus, memory and long-term resilience.
Optimized leuco form
Starts reduced, electron-loaded and more lipid-soluble—a smarter starting state than oxidized methylene blue.
Cellular energy
Supports efficient electron transport and ATP production—the energy your cells use to perform.
Sharper focus
Supports brain energy metabolism for clearer, more productive thinking.
Memory support
Helps support the cellular energy demands behind learning and recall.
Antioxidant redox support
Helps manage reactive oxygen species where cellular energy is made.
Cellular resilience
Supports antioxidant defenses and the cellular processes associated with healthy aging.
WHY LEUCOMETHYLENE BLUE?
A smarter starting state.
Methylene blue works by cycling between two redox states. Our vitamin C formula starts with most of it already reduced—as colorless, electron-loaded leucomethylene blue.
OXIDIZED FORM
Oxidized methylene blue
- Bright blue
- Oxidized state
- Ready to accept electrons
- Can visibly stain
- Cationic character
Vitamin C + electrons
Vitamin C donates electrons inside the gummy, shifting most methylene blue into its reduced leuco state before you take it.
REDUCED FORM
Leucomethylene blue
- Colorless
- Reduced state
- Already electron-loaded
- No blue-mouth mess
- More lipid-soluble character
Colorless by chemistry.
When methylene blue accepts electrons, its electronic structure changes and it no longer absorbs visible light in the same way—so the vivid blue color disappears.
THE FINISHED GUMMY
Why is the gummy purple?
Leucomethylene blue itself is colorless. The gummy’s deep-purple appearance comes from blueberry extract—not blue methylene blue.
It starts reduced, electron-loaded and colorless—while remaining part of the same reversible redox cycle.Explore the full science ↓
PURITY & TESTING
Purity tested for top results.
Our Methylene Blue stands out with the quality ensured in each batch. NooBlue’s Methylene Blue products are third-party certified by the Clinical Testing Laboratories of America (CTLA). This independent certification ensures that what’s inside the product truly matches what’s on the label—pure, pharmaceutical-grade methylene blue with no hidden fillers or contaminants.
With CTLA’s rigorous testing and verification process, you can feel confident knowing you’re choosing a product held to the highest standards of safety, potency, and transparency.

THE REDUCED-FORM EVIDENCE
What the science actually shows.
Leucomethylene blue is the colorless, reduced half of methylene blue’s reversible redox cycle. Explore what researchers have established at the chemical, cellular and human-study levels.
Established chemistry
Direct measurements of reduction, color loss and reversible oxidation.
Cellular evidence
Research on mitochondrial redox cycling, respiration and oxidative stress.
Human MB research
Clinical findings connecting oral methylene blue with memory, attention and brain-network activity.
Oxidized methylene blue and leucomethylene blue are complementary states of the same redox molecule—not separate active ingredients.
Colorless reduced state
Its changed electronic structure no longer produces methylene blue’s vivid visible color.
Already electron-loaded
It begins in the electron-donating half of the reversible redox cycle.
More lipophilic character
Research describes the reduced leuco state as more suited to moving through lipid-rich environments.
Reversible redox behavior
It can be reoxidized into methylene blue and continue cycling.

Molecular characterCationicMore lipophilic
Direct experiments show that ascorbic acid can reduce methylene blue while dissolved oxygen drives the competing back-reaction.
Vitamin C supplies electrons
The 25 mg vitamin C in each gummy acts as the built-in reducing agent.
Oxidized MB accepts them
Electron acceptance shifts the molecule away from its vivid-blue oxidized state.
Leuco MB becomes dominant
Most of the active moves toward colorless, reduced leucomethylene blue.
Oxygen can reverse the shift
The competing back-reaction demonstrates that the redox cycle remains reversible.

Ascorbic-acid reduction kineticsPMID 12553804 ↗CELLULAR AND MITOCHONDRIAL-MODEL RESEARCH
In cultured-cell and mitochondrial models, flavin-dependent enzymes reduce MB to leucomethylene blue, while cytochrome c can reoxidize the leuco state.
Complex IV activity
Greater activity in the mitochondrial enzyme that supports the final stage of cellular respiration.
Cellular oxygen consumption
Higher oxygen use across the study’s experimental conditions.
Enzymatic reduction
Flavin-dependent enzymes use NAD(P)H to reduce methylene blue.
Reoxidation
Cytochrome c can return the leuco state to oxidized methylene blue.
Human research highlights the broader cognitive relevance of oral methylene blue across memory, attention and functional brain connectivity.
Attention and memory retrieval
Low-dose oral methylene blue altered task-related brain activity and was associated with a 7% increase in correct memory-retrieval responses.

Why is the gummy purple instead of blue?
Blue MB
→Colorless leuco
→Purple gummy
Vitamin C shifts most of the methylene blue into colorless leucomethylene blue before you take it. The gummy’s deep-purple color comes from blueberry extract.
Explore the reduced-form science →The formula
Leucomethylene blue is the reduced, electron-loaded form of methylene blue. It is colorless by chemistry, has more lipophilic character and remains part of the same reversible redox cycle.
The formula is designed to avoid the familiar blue-mouth mess because most of the methylene blue has already shifted toward its colorless leuco state.
Each gummy contains 25 mg of vitamin C, which donates electrons to methylene blue and begins the shift toward reduced leucomethylene blue inside the gummy.
Taking it
Each gummy delivers 10 mg of USP-grade methylene blue plus 25 mg of vitamin C. Chew one daily; each bottle provides a 60-day supply.
