Consumer Report: Best Methylene Blue Supplements
Methylene blue—once just a medical dye and malaria treatment—has exploded as a biohacking supplement for brain health, longevity, and energy. But with FDA warnings and controversial claims, which brands are actually safe and effective?
After analyzing clinical studies, user reviews, and expert opinions, here’s what you need to know before buying.
1. What Is Methylene Blue?
Methylene blue (MB) is a synthetic compound originally used to treat:
- Methemoglobinemia (a blood disorder)
- Malaria (since 1891!)
- Urinary tract infections (as a diagnostic dye)
Now, biohackers use low-dose MB (0.5–4 mg/kg) for:
✅ Cognitive enhancement (boosts mitochondrial energy)
✅ Neuroprotection (may slow Alzheimer’s progression)
✅ Antioxidant effects (scavenges free radicals)
“MB is one of the few substances that can cross the blood-brain barrier and improve cellular respiration,” says Dr. Francisco Gonzalez-Lima, a neuroscientist studying MB’s brain benefits .
