How does taking high doses of vitamin C impact health?

Taking high doses of vitamin C being associated with "more is not always better" reflects an important principle in nutrition and supplementation. While vitamin C is an essential nutrient that plays a crucial role in various bodily functions, including the immune system and tissue repair, excessive intake does not necessarily lead to enhanced health outcomes and may even cause adverse effects.

High doses of vitamin C can lead to gastrointestinal disturbances such as diarrhea, nausea, and abdominal cramps. Additionally, there is potential for increased risk of kidney stones in some individuals due to the way vitamin C is metabolized in the body. This principle underscores the importance of moderation and the idea that optimal health is best achieved through a balanced diet rather than relying on high doses of any single nutrient.

In contrast, other options suggest misleading or overly simplistic views on vitamin C’s benefits or effects. For instance, stating that high doses significantly boost absorption does not align with the known limits of the body’s ability to absorb vitamin C, while suggesting it cures many diseases or having no health impact at all lacks evidence from established nutritional science. Therefore, recognizing that higher doses do not always equate to better health captures the nuanced understanding of supplementation.
