Improved Mitochondrial Respiration Improves Health, Cognition

Methylene blue can also be helpful in instances where you have impaired blood flow that prevents the delivery of oxygenated hemoglobin to the tissues. In this case, methylene blue helps counteract the reduced blood flow by optimizing the efficiency of mitochondrial respiration.

Healthy blood flow is particularly important for brain function, and many older people have chronic hypo-perfusion that contributes to neurodegeneration and memory problems. These issues can be prevented by methylene blue.

In summary, inside the electron transport chain in your mitochondria are five complexes, the primary purpose of which is to conduct the electrons generated from food, primarily carbohydrates and fat, in the form of acetyl CoA. Sometimes the electron transport chain gets blocked or impaired, and methylene blue is able to bypass such blockages.

When you’re perfectly healthy, low doses of methylene blue will enhance oxygen consumption, mitochondrial respiration and ATP production above baseline, basically optimizing the whole system. So, it acts as a metabolic enhancer and not just an antidote for metabolic poisons and other inhibitory processes.

The most important complex, Cytochrome c Oxidase, which catalyzes the reaction of oxygen becoming water, is blocked by cyanide. But methylene blue can insert electrons wherever there is a blockage.

What’s more, when you’re perfectly healthy, low doses of methylene blue will enhance oxygen consumption, mitochondrial respiration and ATP production above baseline, basically optimizing the whole system. So, it acts as a metabolic enhancer and not just an antidote for metabolic poisons and other inhibitory processes.

Methylene blue’s action on mitochondrial respiration is also coupled with biochemical upregulation of your oxygen consumption machinery in general, and hemodynamic processes that increase local blood supply to tissues. This upregulation remains even after the methylene blue is expelled from your system (primarily through urination unchanged as your body minimally metabolizes it), and over time, it can actually increase the number of mitochondria. In your brain, this will benefit cognition, as your brain is the most energy-dependent organ in your body.

Methylene blue also activates the Nrf2 pathway. Nrf2 is a transcription factor that, when activated, goes into the cell’s nucleus and binds to the antioxidant response element (AREs) in the DNA. It then induces the transcription of further cytoprotective enzymes such as glutathione, superoxide dismutase catalase, glutathione peroxidase, phase II enzymes, heme-1 oxygenase and many others.
