Vitamin A is known as a vitamin that can maintain eye health. But apparently, vitamin A also has many other benefits for health. Vitamin A or retinol or retinoic acids are important nutrients for vision organs, body growth, cell division, reproductive health system and immune system support. Vitamin A can be divided into two types based on its origin, namely:
- Retinoids are vitamin A derived from animal products.
- Beta carotene is a vitamin A derived from plants.
Vitamin A also has antioxidant properties. Antioxidants are substances that can protect cells against the effects of free radicals. Free radicals can potentially lead to heart disease, cancer, and other diseases. The American Heart Association recommends people to consume antioxidants from beta-carotene such as fruits, vegetables, and grains.
Vitamin A supplements can be beneficial for people who have poor or limited dietary patterns or who require a high intake of vitamin A as in pancreatic disease, eye disease, or measles. The daily amount requirement of vitamin A in the body is 900mcg in adult men and 700mcg for adult women.
