- Used for neurological conditions in some countries. Evidence grade B.
- Mixed clinical trial results. Evidence grade B.
Best-supported outcomes:
- Research interest only.
Where marketing outpaces evidence:
- The claim that "FDA approved" is not supported by the evidence (grade A).
- Marketing often overstates: Brain regeneration.
- Marketing often overstates: Dementia cure.

Common mistakes
- Expecting dramatic cognitive improvement.
- Self-injecting.
Myths vs reality
