I tend to lose focus easily, so I tried this with high expectations. Since it comes in a film form, it is very thin and lightweight, making it easy to carry in a pocket or pouch without being a burden. It was also convenient to be able to easily take it out and consume it whenever needed. It melts in the mouth with almost no foreign object sensation, so it was easy to take, and the fact that I didn't need to drink water separately felt like a big advantage, especially in busy situations. It used to be a hassle to pack drinks or snacks while studying or working, but this product reduced that inconvenience, so I found myself reaching for it often.
Lately, I had been worried about my concentration dropping significantly due to accumulating fatigue, but after taking this product, I definitely felt that the time I could focus had increased. Usually, I would often waste time looking at my phone or getting distracted while studying, but that time has decreased noticeably. It was particularly helpful in situations where I needed to concentrate for a short period or handle important tasks. Because it is easy and convenient to use, it was great for consistent use, and I found it useful not only for studying but also for daily work. Overall, I felt that this product captured both convenience and effectiveness. If you need to focus but lose focus easily, I think it is worth giving it a try.
