You might try lions mane, a mushroom that noticeably boosts my mental clarity.

Also, being older we have a lot more on our mind. So methods to help organize and focus are more useful than ever to me now. Take notes, keep logs, etc.

What supplier are you using for lion's mane? I've had good experience with RealMushrooms.
