Vitamins
Vitamin A
Learn more
Vitamin A (retinol) is a fat-soluble vitamin found in animal products such as eggs, dairy, liver and kidneys. It is important for the normal reproduction of cells (cellular differentiation) as well as good vision and the proper development of an embryo and foetus.
Beta carotene
Learn more
Beta-carotene is a fat-soluble carotenoid found in plants, and is what gives carrots their orange colour. Your body converts beta-carotene into vitamin A (retinol) and is a safe source of vitamin A because your body only converts as much as it needs. Excess vitamin A can be toxic. Vitamin A is important for the normal reproduction of cells (cellular differentiation) as well as good vision and the proper development of an embryo and fetus. Beta-carotene is also an antioxidant so protects the body from damaging free radicals. Sources of beta-carotene include carrots, tomatoes, spinach, lettuce, sweet potatoes, squash and broccoli.
