Hyperactive toddler. Will be helpful?

My son is 2 years 3 months. He is hyperactive most of the time. He is a picky eaters so I have a eating struggle too. He doesn't feeling sleepy at any time . Generally he took a nap in afternoon of 2 hours. At night his activity increases . Putting him to bed at night is very difficult. His weight is 11.3 kg and height is 88 cm. He is also suffering from speech delay . He is able to understand more than we say . But he can not speak much meaningfully. Most of the time talking gibberish. He likes experimental playing which are sometimes dangerous. Very difficult to manage him . Went to our pediatrician and he said these r normal in this age. One of our friend suggest baby dha drop given by his paediatrician. Can I use this drop for my son too?is that will be helpful? Thanks in advance
