# Vitamin A

Vitamin A is an essential fat-soluble vitamin that plays a critical role in maintaining healthy vision, supporting immune function, and promoting skin health. It exists in two primary forms: preformed vitamin A (retinol), found in animal products like liver, fish, and dairy, and provitamin A (beta-carotene), found in plant-based foods such as carrots, spinach, and sweet potatoes. This nutrient is crucial for proper eye function, particularly in low-light conditions, and contributes to the overall health of tissues, including the skin and mucous membranes. A deficiency in vitamin A can lead to vision problems, such as night blindness, and an increased risk of infections. Conversely, excessive intake can result in toxicity, especially from supplements. Ensuring a [balanced intake of vitamin A through a healthy diet](https://cookingenie.com/content/blog/the-path-to-a-healthier-you-building-a-balanced-diet/) is vital for overall well-being.
