What Is Blue Immune? Nutricel's Methylene Blue Fatigue Formula

Blue Immune is our methylene blue fatigue formula: six ingredients built around USP-grade methylene blue and the Root Cause Protocol. The label groups them into three layers: Energy, Mineral Balance, and Antioxidant defense. Every ingredient is listed with its amount, and the product is third-party tested by independent labs.

• Energy: Methylene Blue (6mg) and Magnesium Bisglycinate (40mg). Tucker and colleagues (2018) describe methylene blue supporting the mitochondrial electron transport chain, and Fatima's 2024 review explains that most ATP in cells is bound to magnesium.
• Mineral Balance: Copper Bisglycinate (12mg) and Grass-Fed Beef Liver (900mg). Hellman and colleagues (2002) describe copper as necessary for ceruloplasmin, the enzyme that helps the body handle iron, which is the core idea of the Root Cause Protocol.
• Antioxidant: NAC (266mg) and Organic Camu Camu (7.5mg). NAC supplies the cysteine the body uses to build glutathione, per Rushworth and colleagues (2014), and camu camu adds vitamin C from a whole food.

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 use.

Blue Immune is our methylene blue fatigue formula, built on the idea that methylene blue should not have to work alone. It pairs 6 mg of USP-grade methylene blue with five other ingredients, each aimed at a different part of how your cells make energy. Mitochondria, the parts of your cells that make energy, depend on minerals like copper and magnesium and on antioxidants like glutathione. If one of those is running short, more methylene blue does not fix it, so we built the formula in layers instead.

The formula follows the Root Cause Protocol popularized by Morley Robbins, which treats the relationship between copper, magnesium, and ceruloplasmin as central to how the body manages iron and makes energy. That is why Blue Immune leans on minerals and a whole-food liver source, not methylene blue alone.

The three layers are Energy (methylene blue and magnesium), Mineral (copper and grass-fed beef liver), and Antioxidant (NAC and camu camu). One serving is a single capsule, and a bottle holds 60.

Like the rest of our line, Blue Immune is third-party tested by independent labs, made in an NSF GMP verified facility in the USA, and comes in a vegan, plant-based capsule with no artificial dyes, maltodextrin, cellulose fillers, or rice bran.

USP-grade methylene blue is the core ingredient, and it works inside the mitochondria. Your cells make energy by passing electrons down a chain of proteins, the electron transport chain (ETC), a bit like a bucket line that ends in ATP. Wen and colleagues (2011) describe low-dose methylene blue acting as an alternative electron carrier that hands electrons toward complex IV, which keeps the line moving when earlier steps are slow. Tucker and colleagues (2018) review that work, most of it in cells and animals. We kept the amount at 6 mg because the minerals and antioxidants do the rest of the work in this formula.

Magnesium Bisglycinate is what makes that energy usable. Fatima and colleagues (2024) describe magnesium as a cofactor in more than 300 enzyme reactions and note that most ATP in cells exists as a magnesium-ATP complex, not free ATP. So an energy formula that skipped magnesium would be missing a piece. The bisglycinate form is bound to the amino acid glycine, which is easier on the stomach than cheaper forms such as magnesium oxide.

This layer is the heart of the Root Cause Protocol, and it comes down to copper and iron. Copper Bisglycinate supplies copper, which the body needs to make ceruloplasmin, its main copper-carrying ferroxidase enzyme. Hellman and colleagues (2002) and the StatPearls reference on ceruloplasmin describe it changing iron into the form that can load onto transferrin, the protein that carries iron where it is needed. The Root Cause Protocol's view is that when copper runs low, iron is handled poorly and adds to oxidative stress. The bisglycinate form is bound to an amino acid for better absorption than inorganic copper salts.

Grass-Fed Beef Liver backs up the same layer with a whole food. Liver naturally contains copper, preformed vitamin A (retinol), vitamin B12, and riboflavin, all used in energy metabolism. We paired it with the copper bisglycinate on purpose: the chelated copper gives a known, measured amount, and the liver adds copper and other nutrients the way food delivers them. The liver in Blue Immune is grass-fed.

N-Acetyl L-Cysteine (NAC) supports glutathione, the main antioxidant your cells make for themselves. The body builds glutathione from three amino acids, and the one usually in shortest supply is cysteine; NAC is a stable form of cysteine. Glutathione swallowed as-is mostly breaks down in the gut, which is why NAC is the usual route. Rushworth and colleagues (2014) review NAC raising glutathione inside cells, and Atkuri and colleagues (2007) describe it as a safe way to support cysteine and glutathione levels. In Blue Immune it sits next to the methylene blue, which works on energy production, while NAC supports the antioxidant side of that same process.

Organic Camu Camu (Myrciaria dubia) adds whole-food vitamin C. It is a small Amazon berry, and Langley and colleagues' 2015 systematic review describes it as one of the richest natural sources of vitamin C, along with flavonoids such as quercetin that plain ascorbic acid does not have. We chose a food source to match the whole-food approach of the rest of the formula. A small amount of a flow agent (silicon dioxide) is also included so the powder blend fills capsules evenly.

Blue Immune is not for everyone, and the main reasons come from the methylene blue and the copper. The FDA label for methylene blue injection (Provayblue) carries a boxed warning about serotonin syndrome with serotonergic medications, and our adverse medications list covers more.

Do not take Blue Immune 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 opioids
• Some common allergy and cold medications
• St. John's Wort, 5-HTP, or SAMe

It is also not for pregnant or nursing women or children. The Provayblue label warns that methylene blue can cause hemolytic anemia in people with G6PD deficiency, so they should not take it. Anyone with a copper-handling disorder such as Wilson's disease, or already taking copper or iron, should talk to a healthcare provider first. Some people find it affects sleep if taken late in the evening.

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 is our core formula: 12mg of methylene blue per capsule with Vitamin C Ester and organic cacao. If you mainly want methylene blue itself, start here.

Blue Immune combines methylene blue with copper, magnesium, NAC, grass-fed beef liver, and camu camu for fatigue and cellular energy support, based on the Root Cause Protocol.

Blue Shroom pairs methylene blue with six organic mushroom extracts including lion's mane, reishi, cordyceps, chaga, shiitake, and turkey tail.

Blue Renew is built around GlyNAC with collagen and creatine, aimed at longevity and brain function as you age.

Blue Remove combines zeolite, curcumin, and nattokinase, aimed at circulation and the body's normal inflammatory response.

Blue Liquid is USP-grade methylene blue in a dropper bottle (1%, 10mg per mL), for people who prefer liquid and want to adjust in small steps.

Blue Immune is a layered formula built on the Root Cause Protocol: methylene blue and magnesium for energy, copper and liver for mineral balance, NAC and camu camu for antioxidant support. Each ingredient has a job and an amount on the label. Read the label and decide for yourself.

If fatigue is the main thing you want help with and you want more than methylene blue on its own, Blue Immune adds the mineral and antioxidant support our plain methylene blue products do not have, in one capsule a day. If you are on any medication, check the list above first.

Like the rest of our line, it is third-party tested, made in the USA in an NSF GMP verified facility, and has no synthetic fillers. See the full formula at Blue Immune.
