Vitamin A at a glance
Vitamin A was first discovered back in 1912, by a Polish biochemist named Casimir Funk. Funk came up with the word vitamine, which was later given the name vitamin. Funk was the first to discover vitamins as we know them today, although vitamin A was actually the first one discovered, hence the letter A in the title of the vitamin. You can find vitamin A in natural foods such as oranges and yellow fruits. It can also be found in vegetables as well, such as spinach and fats. When found in vegetables, vitamin A is water soluble, coming in the form of beta carotene. The beta carotene form of vitamin A can be eliminated from your body through natural processes, making it an excellent way to get vitamin A. Vitamin A is required by the body on an every day basis to maintain healthy skin and keep your eyesight on track. There are many people who say that carrots provide enough vitamin A to prevent you from getting night blindness. The fact is, ancient Egyptian doctors prescribed liver in their time, which they said contained enough vitamin A to combat night blindness. Vitamin A is also known as an antioxidant, which makes it ideal in prevention of cancer and useful for anti aging. Along with these benefits, it also helps with your immune system as well. To get the proper absorption of vitamin A, you'll need to consume fat. Those of you who happen to be on a low fat or restricted diet, simply may not be getting the right amounts of vitamin A from your supplements that you may think. To get the proper absorption of vitamin A in your diet, you'll need to consume a high enough level of protein. Protein combines with vitamin A to make it stronger, and help it move through your body. On a normal day, you should be consuming around 5,000 international units (IU) of vitamin A. Depending on your health and your age, you may need to consume more or less. The safest form of vitamin A is beta carotene as mentioned above, and it can be taken in much larger doses. No matter what age you may be, you can feel safe to consume high amounts of vitamin A in the form of beta carotene. If you don't consume enough vitamin A in your diet, you'll end up with a deficiency. A deficiency is never a good thing, as it normally results in skin problems, increased infections, and even night blindness. A prolonged deficiency in vitamin A can put you at a risk for cancer, and you'll also miss out on any benefits of anti aging that the vitamin might have. Although you should begin taking it immediately if you have a deficiency, the effects wouldn't be the same as they would be if you stayed up to date with the right amount on a daily basis. On the flip side, if you are getting too much vitamin A, you'll put yourself at risk for pain in your joints, abdomen, and your bones. Even though too much or not enough can cause you serious side effects, you should always strive for the right amount in your diet. Vitamin A is very important, and should always be included in your diet. You can find it in many foods, and take supplements that include the well needed vitamin. If you are going to take vitamin A or a supplement that includes vitamin A, you should make sure that it's a good quality that will give you no side effects.
