Retinal is a form of vitamin A that is found in animal sources, such as liver, eggs, and dairy products. It is a precursor to retinol and is converted into retinol in the body. Retinal is important for maintaining healthy vision and skin. It is also involved in the production of rhodopsin, a protein that is essential for vision in low-light conditions.
Retinoic Acid
Retinoic acid is a form of vitamin A that is found in animal sources, such as liver, eggs, and dairy products. It is a metabolite of retinol and is involved in regulating gene expression. Retinoic acid is important for maintaining healthy skin and immune system. It is also used in the treatment of acne and other skin conditions.
Carotenoids
Carotenoids are a group of plant-based pigments that can be converted into vitamin A in the body. The most common carotenoids are beta-carotene, alpha-carotene, and lycopene. Carotenoids are important for maintaining healthy vision, skin, and immune system. They also act as antioxidants and protect the body from cellular damage caused by free radicals.
