There is no need to "supplement a lot of nutrition" in senior three. I'm from senior three, and I don't eat much. I did well in the exam. Senior three will not increase the consumption of nutrition, and more nutrition than needed will not bring special benefits, so senior three does not need a special diet.

The nutrition that the brain needs is very simple, basically it only needs glucose, and eating a full meal every day is enough.

The brain basically doesn't need protein, and protein can't prevent fatigue. You don't need to supplement protein unless you do a lot of exercise or need to build muscles. If yes, meat, eggs, milk or bean products are more delicious and cheaper than protein powder. "Dongfang Bili" produces a bunch of various health products, so I won't comment. I'm just saying that no health care product can definitely "improve memory".

The most important thing is to have enough sleep time and good sleep quality. Without this, there is no way to talk about daytime efficiency.

Health care products are basically just psychological effects. If they must be effective, two drugs are recommended. Ritalin can improve attention, and modafinil can help stay up late. But there are side effects.
