- Flexible dosing: Measure single drops
- Better control: Microdose or titrate up slowly
- Avoids fillers: Liquids often have fewer excipients
📏 Typical Dosage (For Reference Only!)
| Goal | Typical Dose | Notes |
|---|---|---|
| Microdosing (daily wellness) | 0.5–1mg | Often ~1–2 drops of 1% |
| Cognitive boost (occasionally) | 2–4mg | 4–8 drops of 1% |
| Clinical studies | 1–4mg/kg (under supervision!) | Higher risk: must be medical-grade |
⚠ Always consult a healthcare provider. MB interacts with SSRIs and can risk serotonin syndrome.
