Is it good for underweight people to take vitamins?
It is generally beneficial for underweight individuals to take vitamins. A multivitamin supplement may be a good choice, and the appropriate dosage should be determined under a doctor's guidance.

Being excessively thin may result from genetic factors or poor digestion and nutrient absorption. Underweight individuals can benefit from eating smaller meals more frequently to gradually improve their constitution. Diet-wise, it's best to focus on high-protein and high-calorie foods, gradually increasing overall nutritional intake. Additionally, consuming vitamin-rich foods such as cabbage and kiwifruit can be helpful. An unstable physical condition may lead to imbalanced blood circulation and affect the circulatory system. Therefore, appropriately supplementing vitamins can help regulate the body’s vital energy (qi) and blood. Vitamins generally support good vision, help alleviate various illnesses, enhance immune function, and maintain normal metabolic processes, including energy metabolism.
While supplementing with vitamins, it's also important to ensure adequate intake of other essential nutrients, including fresh meats such as beef and lean meat. Maintaining a balanced diet with sufficient nutrition in daily life is crucial for overall health.
