vitamin A and how to take it

Vitamin A is a fat-soluble nutrient essential for vision, immune support, skin health, and cellular growth. It exists in two primary forms: preformed vitamin A (retinol and retinyl esters) found in animal-based foods such as liver, dairy, and fish oils, and provitamin A carotenoids (like beta-carotene) found in plant sources such as carrots, sweet potatoes, and leafy greens. Adequate intake of vitamin A supports healthy eyesight (particularly night vision), strengthens the immune system against infections, promotes reproductive health, and contributes to normal organ function.

Vitamin A deficiency can lead to night blindness, dry skin, weakened immunity, and growth impairments, while excessive intake (hypervitaminosis A) may cause toxicity symptoms including nausea, liver damage, and bone issues. Balancing vitamin A with other nutrients like vitamin D, vitamin K2, and zinc is important for optimal absorption and health.

Whether obtained through diet or supplementation, vitamin A plays a vital role in overall well-being, making it one of the most important micronutrients for long-term health.
