Stores today are filled with all kinds of vitamin and mineral supplements, and these supplements are often sold through overwhelming advertising.
However, to this day, there is no well-established concept on how to take vitamins and minerals to nourish the human body. Especially for the intake of certain trace elements, no one can determine the most reasonable dosage. The biggest difficulty lies in the fact that manufacturers cannot determine the user's age, gender, health status, and the environment in which they live and work.
Moreover, a healthy, non-picky person does not need to take multiple vitamins year-round. Therefore, people should not spend money on meaningless things (improper supplementation can be harmful to the human body).
In winter, it is still beneficial to take some multivitamin and mineral supplements appropriately.
People living in adverse living conditions (excessive sun exposure, severe air pollution, harsh climate, etc.) should also take some. People with excessive physical and mental stress consume more vitamins and minerals than usual. Some picky eaters (such as vegetarians) need to use these supplements to balance their intake of vitamins and minerals due to an imbalance in their bodies. For pregnant women, even with a very rich diet, it may not fully meet the body's needs for vitamins and minerals.
In the instructions for multivitamin and mineral supplements, although it is stated how much should be taken daily, it is difficult to say whether this dosage is sufficient or insufficient for a specific person, because each person's specific situation is different. However, one point that needs to be pointed out is that artificially excessive intake of vitamins can be addictive, and once stopped, symptoms of vitamin deficiency may appear. Excessive intake of vitamins A and D is harmful to the human body.
