What Is Blue Boost? Full Formula Breakdown

Blue Boost pairs USP-grade methylene blue with two other ingredients we chose to support absorption and antioxidant balance, instead of putting methylene blue in a capsule on its own.

• The formula contains three active ingredients: 12 mg USP-grade methylene blue, 35 mg Vitamin C Ester (a fat-soluble form of vitamin C), and 235 mg organic cacao (used as the filler in place of inert powders).
• We added Vitamin C Ester because vitamin C reduces methylene blue to leucomethylene blue, and organic cacao because it fills the capsule with a food instead of inert powder.
• As far as we know, Nutricel was the first brand to pair Vitamin C Ester and organic cacao with methylene blue in a capsule. A capsule gives you the same 12 mg every time, with no staining.

Important: The FDA label for methylene blue injection (Provayblue) carries a boxed warning about serotonin syndrome with serotonergic medications, including SSRIs and MAOIs. Review the full adverse medications list before starting any methylene blue protocol.

The structure matters because energy is more than one step. Methylene blue is a redox-active compound that Tucker and colleagues (2018) review for its interaction with mitochondrial pathways (From Mitochondrial Function to Neuroprotection, PMC / NIH). But energy production also depends on electron transport efficiency, oxygen delivery, circulatory function, and oxidative balance working together as a system.

We built Blue Boost with that in mind, so it has a reason for each ingredient instead of methylene blue alone. Below is what each one is and why we put it there.

Methylene Blue USP at 12 mg

Blue Boost uses USP-grade methylene blue at 12 mg per serving, tested at 99.4% purity. USP grade means the material meets United States Pharmacopeia standards for identity, purity, potency, and contaminant limits before formulation begins.

Methylene blue is a redox-active compound. It cycles between its oxidized blue form and a reduced form called leucomethylene blue. That back-and-forth is what lets it take part in cellular energy metabolism.

Yang and colleagues (2017) describe methylene blue taking electrons from NADH through Complex I and is reduced to leucomethylene blue. That molecule then transfers electrons to cytochrome c, feeding them into Complex IV of the electron transport chain. In the process it becomes oxidized back to methylene blue and the cycle repeats (Alternative Mitochondrial Electron Transfer, PubMed).

In that model, methylene blue can bypass damaged or inhibited complexes in the electron transport chain and still support ATP production. Low-dose studies reviewed in Frontiers in Cellular Neuroscience report that it can increase Complex IV activity while reducing oxidative stress (Protection Against Neurodegeneration with Low-Dose Methylene Blue, Frontiers).

Laboratory research has reported increases in cytochrome oxidase activity of roughly 30% and improvements in oxygen consumption of 37 to 70% in laboratory models (Methylene Blue Increases Active Mitochondria and Cellular Survival, MDPI).

A review in PMC on targeting mitochondrial dysfunction with methylene blue reports about 72% oral bioavailability, with much of it circulating in the reduced leucomethylene blue form (Targeting Mitochondrial Dysfunction Using Methylene Blue, PMC / NIH). 12 mg is a low dose compared with medical use.

Vitamin C Ester at 35 mg

Vitamin C Ester, also known as ascorbyl palmitate, is a fat-soluble form of vitamin C created by bonding ascorbic acid with palmitic acid. That change makes it dissolve in fat instead of water (Ascorbyl Palmitate, PubChem).

Standard vitamin C is water-soluble and clears quickly from circulation. Because cell membranes are made of lipids, water-soluble molecules often struggle to enter membrane environments.

Ascorbyl palmitate is an amphipathic molecule, meaning one portion interacts with water while the fatty acid portion integrates into lipid membranes. A 2025 review on vitamin C forms describes it helping protect cell membranes from oxidative damage (Enhanced Vitamin C Delivery, PubMed).

That matters to us because methylene blue is reduced to leucomethylene blue as part of its electron transfer cycle, and vitamin C is a well-known reducing agent for that reaction.

Because Vitamin C Ester can reach fatty parts of the cell, our reasoning is that it can support that reduction closer to where methylene blue works. That is the logic behind the formula, not a result from a study on Blue Boost. Reviews describe ascorbyl palmitate as a bioavailable fat-soluble antioxidant that helps deliver ascorbate at the cellular level (Ascorbyl Palmitate Review, ScienceDirect).

Organic Cacao at 235 mg

Cacao is there because methylene blue is dosed in milligrams, so every capsule needs a filler to reach full volume.

Many products solve this with inert fillers such as rice flour, microcrystalline cellulose, magnesium stearate, or silicon dioxide.

These are cheap and widely used. Some people prefer to avoid magnesium stearate and silicon dioxide, and others simply see no reason to swallow powder that is only there for bulk.

Blue Boost instead uses 235 mg of organic cacao powder. Cacao fills the capsule and brings flavanols, which have their own research on blood flow and cognition.

A study in Scientific Reports found cocoa flavanols improved cerebral oxygenation and cognitive performance in healthy adults (Dietary Flavanols Improve Cerebral Cortical Oxygenation, Scientific Reports).

Additional research has reported improvements in cognitive function and increases in cerebral blood flow following flavanol-rich cocoa consumption (Cocoa Flavanol Consumption Improves Cognitive Function, PMC, Cerebral Blood Flow Response to Cocoa, PMC, Cocoa and Cognitive Performance, PMC).

One limit, plainly: those studies used far more flavanols than 235 mg of cacao powder contains. We use cacao as a better filler, not as a dose of flavanols.

Each ingredient has a different job. Methylene blue interacts at the cellular level to support mitochondrial electron transport, accepting electrons from NADH and delivering them to cytochrome c to support Complex IV activity and ATP production (From Mitochondrial Function to Neuroprotection, PMC / NIH). Vitamin C Ester provides fat-soluble antioxidant support and helps maintain redox balance, supporting the reduction of methylene blue to its active leucomethylene blue form at the cellular level (Ascorbyl Palmitate: A Comprehensive Review, ScienceDirect). Organic cacao replaces inert filler with a food whose flavanols are studied for blood flow (Dietary Flavanols Improve Cerebral Cortical Oxygenation, Scientific Reports / PMC).

There is no stimulant in it. The formula is built around cellular energy, and each ingredient is there for a reason we can explain and link.

Methylene blue is not for everyone. The FDA label for methylene blue injection (Provayblue) describes it as a monoamine oxidase inhibitor and carries a boxed warning about serotonin syndrome with serotonergic drugs. Our adverse medications list goes further and applies at supplement doses too.

Do not take methylene blue if you are currently using:

• SSRIs or MAOIs (the FDA label warns of serotonin syndrome)
• SNRIs or other serotonergic medications such as tramadol, trazodone, or bupropion
• Certain migraine medications, stimulants, or some opioids
• St. John's Wort, 5-HTP, or SAMe

It is also not for pregnant or nursing women. And the Provayblue label warns that methylene blue can cause hemolytic anemia in people with G6PD deficiency, so they should not take it.

Review the full adverse medications list and consult your healthcare provider before starting methylene blue in any form.

Every Nutricel product uses USP-grade methylene blue and is made in an NSF GMP verified facility in the United States, and our capsules are third-party tested by independent labs. The difference between them is what goes in alongside the methylene blue.

Blue Boost uses USP-grade methylene blue (USP.org) and is made in an NSF GMP verified facility in the United States (cGMP Regulations, FDA.gov). It is third-party tested by independent labs for heavy metals, microbial safety, potency, and purity, and the reports are on our third-party tests page.

A capsule avoids the staining that comes with liquid and gives you the same amount every serving. No inert fillers, just a short ingredient list we can explain.

Blue Boost is our everyday methylene blue capsule, a three-ingredient formula combining USP-grade methylene blue with fat-soluble antioxidant support through Vitamin C Ester, organic cacao in place of inert filler, and capsule dosing with no staining. It is the one we would start most people on. If you want methylene blue with a reason behind every ingredient, Blue Boost is a different option from a plain capsule.
