5.Proven, but Be Careful: Caffeine
Caffeine may be an effective treatment for ADHD. Research says it improves your memory and concentration. You probably know that you can find it in things like coffee, soda, and tea. You can also find it in some over-the-counter medicines for things like pain and colds. Keep in mind that a little caffeine goes a long way. Too much caffeine can actually have the opposite effect.
6.Depends: Supplements and Vitamins
Omega-3 fatty-acid supplements are good for your heart. But the benefits for your ADHD symptoms are relatively modest. The same goes for zinc, iron, melatonin, and magnesium. Unless you’re already low in those essential elements, you may not see much change.
