All About Vitamin A

08 5th, 2010

Vitamin A was given the first letter of the alphabet for a name because it was the first vitamin to be discovered. It was found that vitamin A has a large number of uses in the body including keeping eyes healthy, aiding cell growth and also helping boost the immune system. However, vitamin A is not only absorbed directly but it is also created by the body by converting beta carotene into vitamin A.

Vitamin A itself is found in a number of foods such as eggs, milk, liver and meat. Beta carotene that the body can convert into vitamin A is found in many fruits and vegetables, especially the red, orange and green coloured ones. The most important point to remember that consuming too much pure vitamin A can be toxic. It is essential not to exceed the recommended daily allowance for vitamin A. The actual recommended allowance of vitamin A varies depending on a persons age, sex and other factors. While the actual amount of vitamin A consumed may be toxic if the recommended daily allowance is exceeded, there is a far higher limit to how much beta carotene can be consumed. Therefore it is advisable to concentrate on obtaining the greatest amount of beta carotene which the body can then convert to vitamin A, rather than consuming vast quantities of pure vitamin A rich foods.

Many people will remember being told that eating lots of carrots helps you to see in the dark and that is down to the vitamin A that is produced from the high levels of beta carotene that are found in the vegetables. Other foods which have high levels of beta carotene that can be converted to vitamin A include tomatoes and dark green leafy vegetables, such as spinach. Beta carotene is not only used to form vitamin A, but it is also a powerful antioxidant in itself. None of the beta carotene that is absorbed is wasted as any excess after conversion to vitamin A has taken place is used to fight the harmful free radicals within the body. Vitamin A also helps fight infections and illnesses by helping tissues that line various parts of the body, including the eyes, mouth, nose, throat and lungs, to grow and also to repair them if they are damaged to prevent infection. Children also need plenty of vitamin A to help their bones and teeth to develop properly.

The K Vitamin

The K vitamin is essential for the blood to clot to repair injuries. Whenever a person has a bleeding wound, it is the K vitamin that is present in the blood that stops the bleeding and enables most minor cuts to heal quickly.

There are three different forms of the K vitamin. The first variant of the K vitamin is vitamin K1, also known as phylloquinone. This is the form of the K vitamin that is found in types of plant foods. Vitamin K found in plant foods. The second form of the K vitamin is the vitamin K2, or menaquinone. This type of the K vitamin is formed by friendly bacteria in the intestines. Thirdly, there is vitamin K3 which is also known as menadione and is actually an artificial form of the K vitamin. All three of these types of K vitamin end up in the liver where it is used to create the blood clotting substances.

The best natural sources of the K vitamin are green leafy vegetables, such as spinach. However, because the friendly bacteria in the intestine makes one of the forms of the K vitamin it is extremely rare for a person to have a deficiency of the K vitamin and so K vitamin supplements are not needed by the majority of people.

Apart from the main function of helping blood to clot, the K vitamin, specifically the Vitamin K1, has an important part to play in the bone building process. This K vitamin is required to retain the calcium in the bones and redistribute it to where it is needed.

Although a K vitamin deficiency is relatively rare there are certain groups of people who may suffer from it. Newborn babies may not have enough of the K vitamin as they have insufficient bacteria in their intestines to produce it. The majority of newborn babies in developed countries are therefore given a K vitamin injection to tide them over until the natural process takes over. That is the only time that a K vitamin supplement will be taken by most people throughout their lives. However, an extended course of antibiotics may lead to a K vitamin deficiency due to the fact that the antibiotics kill the intestinal bacteria as well as the ones that they are being taken to cure. Again, a K vitamin supplement may be given if the course of antibiotics has to continue for a long period of time.

A Guide to the D Vitamin

01 8th, 2010

The D vitamin is the only vitamin that is not obtained from foods that are consumed. Instead, the D vitamin is actually obtained by sunlight on the skin. There has been a lot of media coverage about the dangers of getting too much sun but it is essential that the skin is exposed to sunlight to obtain the recommended daily allowance of the D vitamin. In reality, the amount of time that a person has to spend in the sun to receive a sufficient dose of the D vitamin is extremely small and just a few minutes a day will be sufficient and not have any adverse effects from the amount of ultra-violet light received.

The most important function of the D vitamin is to help control how much calcium is absorbed from food. The majority of the calcium is used to build strong teeth and bones but it is also needed to send messages along the nerves and to help muscles, such as the heart muscles, to contract. It is the D vitamin that ensures that there is always sufficient calcium in the blood to perform these tasks. Other functions that require the D vitamin relate to the immune system and it is believed that it is also a contributing factor in reducing the risk of contracting cancer and, in particular, colon cancer.

The variant of the D vitamin that is formed under the skin is known as vitamin D3, or cholecalciferol. This D vitamin is created when the ultraviolet in the sunlight reacts with a type of cholesterol that is found under the skin naturally. The D3 is converted into a more active form of the d vitamin in the liver and is then diverted to where it is needed the most. Some of the D vitamin remains in the liver and kidneys to help reabsorb the calcium from the blood. The rest of the D vitamin is dispersed to the bones to help them retain their calcium and the intestines to aid absorption of calcium from food.

Even though the majority of the D vitamin is formed through the exposure of the skin to sunlight there are some foods that do contain some of the vitamin naturally. This form of the D vitamin is known as vitamin D2, or ergocalciferol. This is used in the same way as the other D vitamins and is the type used to create the majority of D vitamin supplements.

All About Vitamin A

Vitamin A was first discovered back in 1912, by a Polish biochemist named Casimir Funk. He 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 to prevent cancer and anti aging. Along with these benefits, it also helps with your immune system as well.

To get the proper absorption of vitamin A, youll 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, youll 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 dont consume enough vitamin A in your diet, youll 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 as well. A prolonged deficiency in vitamin A can put you at a risk for cancer as well, and youll also miss out on any effects of anti aging that the vitamin might have. Although you should begin taking it immediately if you have a deficiency, the effects wouldnt be the same as they would be if you stayed up to date with the right amount on a daily basis.

On the other hand, if you are getting too much vitamin A, youll 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 get 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, or take supplements that include the well needed vitamin. If you are going to take supplements, you should make sure that they provide the right amounts – with no side effects.

The 12 b vitamin is one of the b vitamins that are essential to maintain a healthy body. Otherwise known as Cobalamin, the 12b vitamin is needed for the processes to convert the carbohydrates, fats and proteins from food into energy. 12 b also, more importantly, helps keep the red blood cells healthy and therefore prevent heart disease as well as keeping the immune system functioning at its maximum level. In addition, 12 b is used to create the protective covering of all nerve cells in the body.

The most important function of 12 b is to form healthy red blood cells. However, all cells need 12 b to keep them healthy. It is the white blood cells, amongst others, that need 12 b to help ensure that the immune system functioning properly. All of the nerve cells in the body also need 12 b to form their protective fatty layer. This is essential for all of the nerves but is especially so for those in the brain. If there is not sufficient 12 b to create this protective layer then the brain will not be functioning properly.

Interestingly, the amount of 12 b that the body needs is relatively small but is needed on a regular basis. However, 12 b on its own is not enough as the body cannot absorb it easily. To help the body absorb 12 b the stomach produces intrinsic factor which enables more of the 12 b to be absorbed. 12 b is only found in animal foods such as liver, eggs, fish and meat but most people consume far more than their recommended daily amount of 12 b. This is not a problem as the body can only absorb about half of the 12 b that is consumed. It is also worth noting that the body can recycle the 12 b which cuts down on the impact of a 12 b deficiency. However, strict vegetarians or vegans are likely to require 12 b supplements if they do not eat any animal products that contain 12 b.

If the body does not have enough 12 b then anaemia is the most obvious symptom. Obviously, this is due to the fact that there is not enough 12 b to make healthy red blood cells. Anaemia can also be caused by the body not creating enough intrinsic factor to help absorb the 12 b that is available in the food consumed. The body tends to makes less intrinsic factor once a person reaches 50 and this will lead to less 12 b being absorbed and supplements of 12 b may be required. Kids are also at risk from anaemia because they may not eat the food that contain 12 b. Pregnant women need more 12 b because the baby is absorbing 12 b during the pregnancy to grow properly.
