Too much vitamin C can indeed cause gut issues, such as diarrhea and stomach cramps. While vitamin C is essential for maintaining a healthy immune system, excessive intake can lead to digestive discomfort. Understanding the balance between adequate and excessive vitamin C intake is crucial for maintaining overall health.
What Are the Gut Issues Caused by Excess Vitamin C?
Excessive consumption of vitamin C can lead to several gastrointestinal problems. Here are some common gut issues associated with high doses of vitamin C:
- Diarrhea: One of the most common symptoms of too much vitamin C is diarrhea. This occurs because the body tries to expel the excess vitamin C, leading to loose stools.
- Stomach Cramps: High doses of vitamin C can cause stomach cramps due to increased acidity and irritation of the stomach lining.
- Nausea and Vomiting: Some people may experience nausea or vomiting as the body reacts to the high levels of vitamin C.
- Bloating and Gas: Excess vitamin C can lead to an increase in gas production and bloating, causing discomfort.

The recommended dietary allowance (RDA) for vitamin C varies based on age, gender, and life stage. However, the tolerable upper intake level (UL) for adults is 2,000 milligrams per day. Consuming more than this amount can lead to adverse effects.

|---|---|---|
| Children 1-3 | 15 | 400 |
| Children 4-8 | 25 | 650 |
