To study effectively...
The biggest problems for test takers are stress and fatigue. It's important to study a lot, but it's more important to focus and study efficiently in a short amount of time. Recently, test takers are overloading their hearts by drinking too many energy drinks, and are exposed to unnecessary oil and heavy metals by consuming unverified supplements. If you consume unnecessary oil components, it rather puts a burden on the stomach and the blood that should go to the brain is directed to the stomach to digest food.
Alpine perennials,
Rhodiola is a perennial herb that grows wild in the cold alpine regions of Asia, such as the Himalayas and southwestern China, and is also called a rock stone flower. In English, it is called Rhodiola. Rhodiola rosea has grown naturally by adapting to the adverse conditions of the high mountain area (3,500-5,000m above sea level), such as bad weather, strong ultraviolet rays, severe cold, lack of oxygen, and short sunlight, so the plant itself has strong biological defense substances. 
Sherpa's health functional food 
Since about 3,000 years ago, Rhodiola Rosea has been used as a tonic in Europe, and in Russia, Rhodiola extract has been fed to people exposed to severe stress, such as soldiers, athletes, astronauts, and submersible crew members. Rhodiola is well known to mountaineering experts in Korea as the Sherpa who guides Himalayan mountain climbing has a habit of chewing the roots of Rhodiola. Rhodiola Rosea extract is a functional ingredient recognized as a raw material for healthy functional foods and can help improve fatigue caused by stress when consumed 200-600mg per day.  There is a study that it helps to increase endurance, so it is good not only for test takers, but also for athletes, and those who are stressed out at work and work overtime frequently.
Health functional food for endurance enhancement,
Migratory birds fly thousands of kilometers without rest or food when the seasons change. The substance that scientists discovered after studying the secret is octacosanol. Migratory birds constantly peck grain in the fields after harvest and then migrate. This is to obtain octacosanol from rice left after harvest. Octacosanol is also a health-functional food that has been recognized for its endurance enhancement functionality. The downside is that it is expensive, but taking 7 to 40 mg a day is helpful for students who need endurance for a long time.
tension-relieving amino acids,
L-theanine is a type of amino acid that increases the generation of alpha waves in the brain and helps relieve tension caused by stress. alphabet is a brain wave that comes out when you meditate with your eyes closed or when you are at rest. It is a brain wave that makes you feel comfortable. It is an amino acid that is biosynthesized in the roots of plants and stored in tea leaves. It is a component that determines the unique flavor of tea, such as umami and sweetness. L-theanine is a functional ingredient recognized as a raw material for healthy functional foods, and taking 200 to 250 mg a day helps relieve tension caused by stress.
