Can vitamin C chewable tablets be taken long-term?
When taken as directed by a healthcare provider, vitamin C chewable tablets can generally be taken long-term. However, if taken arbitrarily without medical guidance, they are usually not suitable for long-term use. Detailed explanations are as follows:

Vitamin C chewable tablets are rich in vitamin C, a water-soluble vitamin. Excess amounts can be excreted through urine, making it unlikely to accumulate to harmful levels in the body. Therefore, when taken under medical supervision, long-term use is generally safe. For individuals with special needs, such as the elderly, pregnant women, or breastfeeding mothers, appropriate long-term supplementation under a doctor's guidance can also be beneficial, as vitamin C helps strengthen the immune system, promote wound healing, and provide antioxidant effects.
However, if taken arbitrarily without medical advice, long-term use is typically not recommended. Prolonged self-administration of vitamin C supplements may cause the body to become dependent on external sources of vitamin C. Once discontinued abruptly, symptoms of scurvy may appear. Frequent use of vitamin C chewable tablets may also damage tooth enamel and affect oral health.
It is recommended to strictly follow medical instructions when taking vitamin C chewable tablets. During treatment, individuals should closely monitor their physical response, and seek medical attention promptly if any adverse symptoms occur.
