What is vitamin A otherwise known as?

Update:15-07-2021

Vitamin A is also known as ……….all-trans-Retinol, Retinals, and alternative provitamin A-functioning Carotenoids including all-trans-beta-carotene.

Vitamin A is a generic term that refers to fat-soluble compounds found as preformed vitamin A (retinol) in animal products and as provitamin A carotenoids in fruit and vegetables. The three active forms of vitamin A in the body are retinol, retinal, and retinoic acid.

The best sources of vitamin A are:

Cod liver oil.
Eggs.
Fortified breakfast cereals.
Fortified skim milk.
Orange and yellow vegetables and fruits.
Other sources of beta-carotene such as broccoli, spinach, and most dark green, leafy vegetables.
Vitamin A is key for good vision, a healthy immune system, and cell growth. There are two types of vitamin A. This entry is primarily about the active form of vitamin A -- retinoids -- that comes from animal products. Beta-carotene is among the second type of vitamin A, which comes from plants.
The American Heart Association recommends obtaining antioxidants, including beta-carotene, by eating a well-balanced diet high in fruits, vegetables, and whole grains rather than from supplements until more is known about the risks and benefits of supplementation.

High doses of antioxidants (including vitamin A) may actually do more harm than good. Vitamin A supplementation alone, or in combination with other antioxidants, is associated with an increased risk of mortality from all causes, according to an analysis of multiple studies.
