I can speak about my experience, as someone that's ADHD, and has poor memory.
I combined it with bacopa monnieri.
My working memory feels like it's gotten a ton better. It took a few weeks for me to realize effects. I was no longer constantly forgetting things, able to manage more while coding, and able to participate a whole lot more during work meetings, as I could actually recall things more readily. I would say that this is just placebo, except that my wife also noticed that I was not constantly forgetting everything.
With the concerta shortage hitting my area, I actually stopped taking my stimulants for about 2 months, and while my hyper active tendencies didn't go away, I was able to still perform at work. Having a better working memory made context switching much less expensive. I no longer feel dependent on my meds, and only take them when I know I'll be driving for long periods of time, as they do make me a safer driver.
Side effects
Occasional headaches for the first two weeks, this was fixed by ensuring that I had enough magnesium in my system. Also, if you're taking capsules, start out with half the daily dose for a few weeks. Also, a noticeable decrease in sex drive. I think it comes back after a few weeks though. Maca root also counters this- if you see this as a problem.
Also, I will say that no supplement beats out good sleeping habits, diet, and exercise, so your mileage may vary and that's where I would personally start.
