Ingredients

Suggested Use

Methylene Blue is a mitochondrial optimizer and cognitive enhancer that’s been used in medicine for over 100 years. Our USP-grade capsules deliver 10mg per dose, supporting brain health, enhancing mental clarity, and boosting cellular energy production. Unlike messy liquid forms, our capsules are precisely dosed, convenient, and easy to take—making daily Methylene Blue supplementation simple and hassle-free.

Methylene Blue acts as an alternative electron carrier in the mitochondrial electron transport chain, enhancing ATP production. It also has neuroprotective properties and may support healthy brain aging. Each capsule provides a precise 10mg dose for consistent cognitive support.
