Fatty acid complex feels like my Adderall

I started taking this stuff for joint pain a few weeks ago. I’ve taken for a day or two it in the past here and there but didn’t like taking it because it made me feel “switched on”, but my pain has been getting worse lately so I figured I’d give it an honest shot.

So far the energizing/motivation effect has held steady, it’s not placebo.

I’m aware that fish oil is sometimes helpful for people with ADHD (which I have, and I’m prescribed Adderall, but I’m not taking at the moment), but I’ve taken fish oil from reputable sources before and not felt anything from it.

This product isn’t fish oil, but it’s in the same ballpark. Anyone have any idea why it straight up feels like a strong stimulant to me?
