It seems to have heightened my focus a bit.

It does give me better focus during the workday.

So far it has been nice. I do get some sense of increased mental tenacity, like I can slow my thoughts or speed up my processing.

Helped with focus, but not as impactful as previous experience with Qualia Mind. Though, given it's the less premium version, that is to be expected. I felt more focus in the past when using just Qualia Mind, or just Qualia Nootropic Energy, than Qualia Focus. Still, I felt it gave me sharpness and alertness to where I think the affordability aspect of Qualia Focus makes it viable.
