How Often to Use Methylene Blue

For oral methylene blue supplements, the “how often” depends on your purpose, body weight, and tolerance, and should follow a low‑to‑moderate dose approach to avoid diminishing or harmful effects.

General starting point

• Beginners: 1–3 drops per day (about 0.1–0.2 mg/kg body weight) 

• Most common supplement range: 20–50 mg/day for general mitochondrial support or cognitive enhancement

• Typical daily use: Many people take it once daily in the morning or evening, or split into two smaller doses if preferred.

By purpose and weight 

• General mitochondrial support: 5–15 mg/day (start low, increase gradually).

• Cognitive enhancement/memory: 0.5–2 mg/kg/day (e.g., ~48 mg/day for a 95 lb person).

• Mood support: 15–50 mg/day (start low).

• Neuroprotection: 0.5–1 mg/kg/day (longer‑term use).

Example:
A 150‑lb (68 kg) person aiming for a standard 1 mg/kg dose would take ~68 mg/day. If using a 1% liquid (10 mg/mL), that’s ~7 mL/day — or ~140 drops if each mL is ~20 drops.

Frequency tips

• Once daily is common for most users.

• Some take it twice daily (morning and evening) for sustained effects.

• Avoid high‑dose “loading” — methylene blue follows a hormetic dose‑response curve: low doses boost mitochondrial function, but high doses can impair it

• Increase dose gradually, one drop or small increment at a time, and monitor for side effects (e.g., blue urine, dizziness, nausea).
