I have been running ginkgo biloba for a year and the honest summary is that the effect is smaller than the internet suggests and real.

The comparison group matters more than the compound when the outcome is something as fuzzy as focus.

Cold storage, light protection, and a date on the vial. Boring, and it removes half the variables.

What surprised me is how much of the perceived benefit was routine and attention rather than pharmacology.

My rule now: if a claim cannot survive being written down with the numbers attached, it is marketing.

Interested in the methods more than the conclusion.
