What Does Provitamin Mean?
The term "provitamin" is used when describing a substance with little vitamin function but which can be converted into a vitamin by natural metabolism.
Best Way To Get Carotenoids
The bioavailability of provitamin A 🗗 is lower than once believed. So it is difficult to fulfill the daily requirements through plant foods alone.
For instance, β-carotene is only one-twelfth as effective as retinol (preformed vitamin A).
When you are eating foods high in beta-carotene, it is better for absorption and synthesis of vitamin A if you eat them together with fat.
Also, eating anything high in carotenes that is cooked is better than raw because your body can digest it better.
Beta-carotene is studied extensively for its health benefits, but supplementation 🗗 at doses higher than recommended intakes have adverse effects.
Why Do We Need Vitamin A
Vitamin A is essential for our health. It is a powerful antioxidant. When it moves through your body, it scavenges damaging free radicals and fights inflammation.
An adequate intake of dietary vitamin A is essential for normal vision, growth, the functioning of the immune system, etc.
A high intake of carotenoids, from vegetables and fruits, does not seem to cause hypervitaminosis A. Unlike overconsuming preformed vitamin A.
