Getting brain-boosting nutrients from food is far better than medication. Eat more eggs; they contain lecithin, which is very beneficial for the brain. Also, eat deep-sea fish. These foods are good for your brain and won't cause hair loss. On the contrary, they can promote hair growth.

I eat a loooootttt of eggs and meat and butter. I am mostly carnivore, for health reasons.
You're already very smart, why do you need to further improve your IQ? Are you trying to surpass Einstein? People who thrive in the crypto world already have very high IQs. If you keep trying to improve your IQ, you'll see everyone else as fools, and you'll suffer a lot. 😄
I am more so looking for sustained focus, flow optimization and energy. Thank you, for the compliment! 🙂 I already have suffered and learning to have more patience.
