I am a brain nutritionist who has done extensive research and wrote about what I learned. The research I did showed that the best supplements to use for brain power were:
Brain Glucose is another popular supplement that is sold under many names, but you need to be sure to read the label. There are two main types of Brain Glucose: Type 1 is the kind you can get from fruit, and you can buy it in capsule form. You buy it by the bottle or by the pill and the amount you get will be around 12 grams or 1 pill. You should buy a few capsules of this. It will come with some basic information, but it is not really a good idea to add extra water, because that would mean you are taking too much. The amount you will be getting will depend on the brand you choose. There is a reason why there is a name for this type, and it is called 'brain power' in general. When you are using this type, you will notice that you will have to do some mental exercises, like writing a letter, watching a video, listening to a song, etc.
