                                While severe adverse effects from consuming excessive dietary vitamin C are rare, high-dose supplementation can cause gastrointestinal distress and, in specific cases, lead to more serious issues. Understanding the distinction between natural food sources and concentrated supplements is key to determining if too much vitamin C can be harmful.
