Introduction

In general, for mild cold and flu symptoms, an appropriate amount of vitamin C supplementation may help alleviate symptoms and shorten the duration of the illness. However, for severe cases of influenza, relying solely on vitamin C may not effectively relieve symptoms or accelerate the recovery process. If discomfort occurs, timely medical attention is recommended. In daily diet, it is recommended to choose foods according to your own taste and needs.

Generally, for mild cold and flu symptoms, appropriate supplementation of vitamin C may help alleviate symptoms and shorten the duration of illness. However, for severe cases of influenza, relying solely on vitamin C may not effectively relieve symptoms or accelerate the recovery process. If experiencing any discomfort, it is recommended to seek timely medical attention. Detailed analysis is as follows:

Vitamin C is a vitamin with multiple physiological functions, primarily involved in various biochemical reactions within the body. It acts as an antioxidant, promotes collagen synthesis, enhances immunity, aids in detoxification, and facilitates iron absorption. Consequently, for mild cold and flu symptoms, appropriate supplementation of vitamin C may help alleviate symptoms and shorten the course of the illness. Individuals who regularly take vitamin C may experience reduced duration and severity of symptoms when infected with the common cold.

However, for severe cases of influenza, relying solely on vitamin C may not effectively relieve symptoms or accelerate the recovery process. Influenza is caused by the influenza virus and requires comprehensive treatment, including rest, adequate hydration, fever-reducing medications, and, when necessary, antiviral drugs. Vitamin C should not be regarded as the primary treatment method for influenza.

In daily diet, it is recommended to consume an appropriate amount of food based on personal taste and needs, with balanced combinations to meet individual nutritional requirements.
