Can taking multivitamin tablets boost immunity?

In general, taking multivitamin tablets can help enhance immunity. The detailed analysis is as follows:

Multivitamin tablets are rich in various nutrients such as vitamin A, vitamin B, and minerals including calcium, iron, and zinc. These components help prevent multiple diseases caused by deficiencies in vitamins and minerals, supplement essential nutrients for the body, and thereby improve the body's immune function. Additionally, the calcium contained in multivitamin tablets effectively promotes bone growth. The iron content helps alleviate symptoms of iron-deficiency anemia.

Multivitamin tablets are dietary supplements, not medications. They should be taken according to a doctor’s advice and in the recommended dosage—overdosing should be avoided, as it may lead to vitamin toxicity. Patients with chronic renal failure or hypercalcemia should not take these tablets. Some individuals may experience gastrointestinal discomfort after taking multivitamin tablets. If any adverse symptoms occur, discontinue use immediately and seek medical attention promptly to avoid delaying treatment.
