10 Best Methylene Blue Brands (Expert Review)
We’ve compiled this list of standout methylene blue brands based on thorough testing and analysis. Each one brings something valuable to the table, whether that’s superior purity, exceptional customer service, or innovative formulations.
1. aSquared Nutrition
aSquared Nutrition approaches methylene blue supplementation with a comprehensive synergistic formula. Their capsules deliver 12mg of pharmaceutical-grade methylene blue per two-capsule serving, combined with carefully selected compounds that work together to support brain energy, focus, and mitochondrial function.
The formula includes 300mg of cacao powder, rich in flavonoids and theobromine that help promote cerebral blood flow and oxygen delivery to the brain. Alpha lipoic acid supports mitochondrial energy and antioxidant recycling, while vitamin C ester protects the methylene blue from oxidation and enhances formula stability. MCT oil powder provides fast-acting brain fuel and may assist in nutrient absorption.
What distinguishes aSquared Nutrition is their attention to capsule design. They use white capsules specifically to protect sensitive compounds from light degradation, helping preserve potency and ensure consistent effectiveness. This thoughtful detail shows their commitment to maintaining product quality throughout the shelf life.
Third-party testing in an ISO 17025 certified facility ensures high standards of purity, potency, and quality for safe and reliable supplementation. The clean, non-GMO formula is crafted with vegan-friendly ingredients and manufactured in the USA. Their approach appeals to users who want more than basic methylene blue, seeking a complete nootropic stack designed for daily cognitive support and optimal brain performance.
2. Hourten
Information about Hourten as a methylene blue brand is limited in current supplement databases and online resources. This may indicate a newer market entry, regional availability, or specialized distribution that hasn’t yet established a strong digital presence. When evaluating lesser-known brands like Hourten, several key verification steps become particularly important.
For any methylene blue supplement, consumers should confirm USP-grade or pharmaceutical-grade certification, third-party testing by accredited laboratories, transparent labeling of methylene blue concentration, and formaldehyde-free formulation. The manufacturing facility should comply with current Good Manufacturing Practices (cGMP) and ideally be located in countries with strong regulatory oversight.
If considering this brand, reach out directly to the company for Certificates of Analysis, detailed ingredient lists, testing protocols, and information about their manufacturing processes. Reputable brands readily provide this documentation to concerned consumers. Without verified information about purity standards, testing procedures, and quality controls, it’s difficult to assess whether Hourten meets the benchmarks set by established methylene blue supplement providers.
3. Nutricel Supplements
Founded in 2020, this family-owned American brand was born from personal experience with chronic fatigue and the frustration of traditional medicine missing root causes. Their methylene blue capsules feature USP Reference Compliant purity, which means they consistently achieve purity levels above 99% with minimal contaminants. What really sets them apart is their focus on cellular health rather than just symptom management.
Their flagship product delivers 12mg of pharmaceutical-grade methylene blue per capsule, enhanced with vitamin C ester for improved absorption and organic cacao powder rich in flavonoids.

Nutricel stands out with their diverse product line. Beyond their standard formula, they offer specialized versions combined with mushroom extracts (lion’s mane, reishi, cordyceps), grass-fed beef liver with vitamins A and E, nattokinase with zeolite and turmeric, and glycine plus NAC for anti-aging support. The capsule format prevents the messy staining issues that come with liquid formulations, making daily supplementation much more convenient.
All products are manufactured in NSF-certified, GMP-compliant facilities in the USA.

Their 60-capsule bottles provide a two-month supply at the recommended dosage, making this an accessible entry point for people exploring methylene blue supplementation.
