GlossaryVitamin A Toxicity (Hypervitaminosis A)

excessive vitamin A intake causing harmful health effects

Vitamin A Toxicity, also known as Hypervitaminosis A, occurs when there is an excessive accumulation of vitamin A in the body, typically due to overconsumption of supplements or certain animal-based foods. This condition can lead to symptoms such as nausea, dizziness, headaches, and even more severe effects like liver damage, bone abnormalities, and hair loss. It is important to maintain a balanced intake of vitamin A to avoid these adverse health effects.
