I have tried every supplement/herb/nootropic you can think of + more. I've also asked this question to many of the folks I interviewed for my book about adult ADHD.

The only thing that was directly effective was prescription stimulant medication (in my case, a low dose of Vyvanse).

The biggest impact outside of that was lifestyle design, self forgiveness, and an array of the "healthy lifestyle" choices you've mentioned.

I truly empathize with your quest for a helpful supplement because I've had the same curiosity and have done the same search, but to no avail.

Even more frustrating is that you'll find some studies that vaguely point to some vitamin that "helps boost focus in those with ADHD!" But once you dig into the data, the "results" are some insignificant "boost" & are generally just a side effect of study participants getting better sleep/less anxiety/etc.
