Realistically, there is no reliable means of significantly improving intelligence. Sleep, a healthy diet, and exercise seem like the best ways of modestly boosting and otherwise maintaining existing intelligence.
However, there are way of increasing energy and improving focus, and this is where I'd like to pick the brain of imminsters.
Let's look for a list of items that:
1) Improve Energy, and/or;
2) Improve Focus
I'll begin with relatively well-studied examples...
For Energy & Focus: Rhodiola Rosea, Strattera (in some individuals)
For Focus: Methylphenidate
What other options come to mind?
