YOUR DAILY RITUAL

One drop in water. One shift in performance. BIOKEY Methylene Blue fits seamlessly into your routine — no friction, no fluff. Just results.

DIRECTIONS

For daily cognitive support, adding 5–10 drops of methylene blue to water is recommended. If a rapid nootropic effect is preferred, a few drops can be placed under the tongue—though this may temporarily stain the tongue, which is completely harmless. Alternatively, topical application or use in a nebulizer can offer additional health benefits.
