Vitamin A: Sources and Functions

Vitamin A is a fat-soluble vitamin. This means it has the ability to travel through fat, and it can be stored in fat longer. Fat-soluble vitamins can go right through a cell.

Water-soluble vitamins can’t do this. Fat-soluble vitamins can affect the deep parts of the cell and DNA. 

There’s some real interesting things about vitamin a .

Vitamin A deficiencies can affect what your skin turns into at the genetic level.

Symptoms of a vitamin A deficiency can include:

  • • Flaky skin
  • • White dots on the skin
  • • Dandruff
  • • Vision problems (night blindness)
  • • Infections
  • • Lack of lubrication of the eye or mouth 

Great vitamin A sources:

  • • Cod liver oil 
  • • Liver 
  • Butter
  • Eggs (especially the yolk)
  • • Cheese 

There are also foods that have previtamin A. This means it has to be converted into the active form a vitamin A.

This conversion only takes place in certain parts of the body at certain percentages. 

Sources of previtamin A:

  • • Kale
  • • Spinach 
  • • Carrots
  • • Sweet potatoes 
  • • Greens

So if you can’t see at night when you’re driving at night and it’s hard to see , that’s a vitamin a deficiency .

Also , lubrication of the eye and the mouth and anything , any granular secretion if like if you don’t have enough of that lubrication , that’s a vitamin a deficiency .

Also , infections , sinus infections , ear infections , lung infections all can be triggered by a low vitamin a level , so it has a lot to do with your immune system .

So vitamin a , gives support to the eye , to the skin , to the immune system , to the inner skin too around your inside your nasal passages .

Now , here’s what people don’t realize .

Vitamin A is in cod liver oil , It’s in liver .

It’s in butter .

It’s in eggs , especially the yolk .

It’s in cheese .

That’s the active form of vitamin a called retinol .

Now , it’s true that , kale , spinach , carrots , sweet potato , and greens also have vitamin a and they have a lot of vitamin a , but here’s what people don’t realize .

This is a pre vitamin a , so anything vegetable has a pre vitamin a .

It’s not an active form .

It’s not retinol .

It to be converted into an active form .

That conversion only takes place , at certain parts of your body and in only certain percentages .

So if you’re lucky , you might get between 4 to 6 percent conversions

Foods high in vitamin A

So if you’re consuming a 100 milligrams , let’s say , of vitamin a from kale , you’re only getting 4 to 6 percent of that .

Okay , so just because you’re eating kale doesn’t mean you’re gonna get enough vitamin a .

Especially if you’re not consuming these products .

So that’s just some interesting information .

What causes a vitamin A deficiency?

What causes a vitamin a deficiency ?

Now it could be you’re not consuming enough of these or maybe say you’re not converting these right here , but more likely you probably are consuming enough vitamin a , but the deficiency comes from the ability to convert and that has to do with your gut .

If your digestive system is damaged or you have a history of taking antibiotics or you have leaky gut or some type of digestive issue , chances are you can’t convert this .

So everything’s gonna dry out .

Your hair’s gonna dry out .

Your skin’s gonna dry .

Eyes dry .

So you’ll start manifesting vitamin a deficiencies .

What causes a vitamin A deficiency?

The other cause of vitamin a deficiency is a lack of bile , b I l e , from the gallbladder .

Why ?

Because the gallbladder helps you break down fats and breaks down the fat soluble vitamins so your body can start utilizing them .

So if you don’t have a gallbladder that means you probably don’t have enough bile to absorb vitamin a .

You might have to take some bile as an as a supplement .

So , let’s say you get , have another you just have a congested liver , and the symptoms of that would be bloating , burping , belching , right shoulder pain , constipation .

Those are indications that you don’t have enough bile .

It could be because your stomach is not acid enough .

So you have heartburn .

Well that means that that means you don’t have enough acid because in order for you to release your own bile you need a very strong stomach .

So it could be that the stomach is not releasing the bile to help you absorb vitamin a .

heartburn

So again , I just want to give you that background in case you’re taking vitamin it’s not working because you probably can’t absorb it .

So I hope that gave you some data about vitamin a .
