Overview
Pharmaceutical grade (USP) methylene blue at 20mg per capsule, paired with vitamin C, sold as a 120-capsule two-bottle supply positioned as a focus and memory support supplement.
Methylene blue has moved from a lab and clinical compound into a nootropic supplement marketed for mental clarity and focus, and this version is labeled USP pharmaceutical grade with vitamin C added. It is also formulated to fit gluten free, halal, kosher, vegan, and vegetarian diets. Methylene blue is known to interact with certain antidepressants such as MAOIs and SSRIs, raising serotonin syndrome risk, a general caution that applies to methylene blue supplements broadly and is not something this listing calls out itself.
- 20mg USP methylene blue per capsule
- 120 capsules, two-bottle supply
- Vitamin C included
- Vegan, halal, kosher, gluten free
Who it's for
For adults interested in methylene blue as a focus and memory-support supplement who are not on antidepressant medication. Not for anyone currently taking an SSRI or MAOI without medical guidance first.

Performance notes
Methylene blue's studied effects are mostly around mitochondrial and cognitive support at low doses, which is the basis for its use as a focus supplement here. The listing notes a high-potency 2 percent capsule strength and pairs it with vitamin C, though it does not explain what the vitamin C addition is meant to do alongside the methylene blue.
