According to various research results and expert opinions, adjusting the daily intake based on caffeine, a representative antioxidant component and the main protagonist of alertness, is said to greatly benefit health.

According to an article published by the American consumer and science website BGR (Boy Genius Report), a meta-analysis of over 100 coffee and health-related studies conducted worldwide revealed that for healthy adults, enjoying a maximum daily caffeine intake of 400mg (about 5 cups of 150mL each) can yield positive well-being effects. This figure is the same as the daily caffeine limit recommended by the Food and Drug Administration.

Additionally, the recommended intake amounts based on circumstances can be summarized as follows:

• Healthy Adults: Up to 400mg per day
  (About 5 cups based on 150mL, but the caffeine content per cup may vary depending on the type of coffee and brewing method.)

• Pregnant Women: Up to 300mg per day
  Lower intake is recommended for the health of the fetus and the stability of the mother.

• Children and Adolescents: Up to 2.5mg per kg of body weight
  For example, for a 40kg elementary school student, it is recommended to consume no more than 40×2.5=100mg per day for safety.

Caffeine provides health benefits due to its antioxidant properties while also enhancing alertness and concentration. However, since individual sensitivity to caffeine varies, some people may experience anxiety or insomnia from excessive caffeine intake. Therefore, it is important to find the appropriate intake amount that suits you.

In conclusion, to enjoy well-being effects, healthy adults should limit themselves to 400mg per day, pregnant women to 300mg, and children or adolescents should be careful not to exceed the recommended amount based on their weight (2.5mg per kg).
