I've been using Get Dopa for a couple of months now and while I couldn't tell you exactly what it's doing, my mood feels more stable, I can focus better without slipping into the "nine hours have passed and I forgot the outside world exists" hyperfocus and I'm finding it easier to do all those little tasks that stack up into a big pile of overwhelm (for example: I put clean laundry away, straight away, where it belongs, not on a random chair to rot for a month!) It's not a miracle cure and it's not made my ADHD go away but it's definitely made it easier and more manageable to live with.
