At present, some brain health care products on the market may contain psychotropic drugs. Long-term use can not only help students improve their learning efficiency, but also produce dependence, leading to insomnia, anxiety and rapid heartbeat. Some manufacturers illegally add pharmaceutical ingredients in order to protect the market and expand sales.

It is suggested that high school students are in the period of growth and development, and health care products are suitable for specific groups, which can neither improve test scores nor improve IQ. The so-called fast-acting health care products have greater side effects. It is better to eat an egg every day, drink a bowl of pure soybean milk, make a steamed fish and peel a red apple, which will be more practical and nutritious. Food supplement is safer than eating health care products.
