Introduction
Generally, taking vitamin C does not cause black stools, but if consumed in large amounts, it might lead to darkening of the stool. Vitamin C, as a key component in the human body, helps improve physical health and enhances disease resistance. Usually, vitamin C does not affect the gastrointestinal tract, so bowel movements typically remain unaffected. Additionally, vitamin C has antioxidant properties that help delay cellular aging.
Taking vitamin C usually does not turn stool black, but if large amounts of vitamin C are consumed, the stool may turn black. The specific analysis is as follows:
1. Generally does not turn black
As a key component in the human body, vitamin C helps improve physical health and resist diseases. Taking vitamin C typically does not affect the gastrointestinal tract, so stool generally does not turn black. Additionally, vitamin C has antioxidant properties that can slow cellular aging and promote cholesterol metabolism.
2. May turn black
However, if large quantities of vitamin C are taken over a long period, the iron content in supplements may fail to be properly digested and absorbed, and instead be excreted in the stool, causing the aforementioned discoloration. In such cases, symptoms can be relieved by appropriately reducing vitamin C intake and drinking warm water.
It is recommended to take vitamin C in moderation during daily life to maintain balanced nutrient intake. Engaging in appropriate physical activities can also help improve overall physical fitness.
