Can apple juice supplement vitamin C?
Under normal circumstances, freshly squeezed apple juice that is consumed promptly can provide a small amount of vitamin C. However, apple juice that has been stored for a long time or has undergone processing typically loses most of its vitamin C content. A detailed explanation is as follows:

Freshly squeezed apple juice consumed immediately without added ingredients retains more vitamin C, and moderate consumption can help supplement this nutrient. Consuming it together with citrus fruits can further enrich nutrient intake and better meet the body's daily nutritional needs.
If apple juice has been stored for an extended period or is a commercially processed bottled product, its vitamin C content may be significantly reduced due to oxidation or high-temperature processing, thereby losing its nutritional benefit. Such juice mainly provides sugar and water, and is unlikely to fulfill the body's requirement for vitamin C.
In daily life, vitamin C can be obtained from a variety of fresh fruits and vegetables. Maintaining a diverse diet and seeking professional medical advice promptly when experiencing physical discomfort can ensure adequate and balanced nutrient intake.
