Vitamin A Benefits

Vitamin A provides very good examples of the holistic functioning of the body’s countless systems; in particular the way in which various nutrients depend upon each other if they’re to operate effectively. A deficiency of the essential mineral, zinc, for example, has an inhibiting effect on the process by which vitamin A is metabolised and activated for use within the body.

Deficiency of vitamin A, on the other hand, is known to contribute to the anaemia caused by iron deficiency. It appears that vitamin A is essential to make iron available for the production of oxygen carrying red blood cells and supplementation with vitamin A has therefore been shown to help in the alleviation of anaemia when combined with the supplements of iron which are of course also necessary.

Not surprisingly, therefore, vitamin A is also required for the proper functioning of the immune system and in particular for the development of the white blood cells which are vital for the body’s effective immune response. Deficiency in vitamin A has been shown to lead to an increase in the incidence and severity of various infectious diseases, including HIV and measles, which remain a major cause of mortality in the developing world, particularly amongst children.

Vitamin A is also known as a powerful anti-oxidant which operates with vitamins C and E, and the minerals selenium and zinc, to destroy both fat and water soluble free radicals. So important is this anti-oxidant role of vitamin A, that some research has suggested it may play a part in combatting certain common cancers, although this issue remains controversial. There are two types of vitamin A of which to be aware; retinol, also known as preformed vitamin A, and the provitamin A carotenoids, of which betacarotene is the most important and best known, which may be converted to retinol within the body. Rich food sources of retinol vitamin A are meat, especially offal such as liver, oily fish and fish liver oil, and dairy produce. Betacarotene and other carotenoids are principally derived from fruits and vegetables.

The US Recommended Dietary Allowance (RDA) for vitamin A is 3,000 IU (900 mcg) per day for adolescents over 14 and adults. In Europe the recommended figures are slightly lower at 2,664 IU (800 mcg). Both these figures are supposed to be sufficient to obtain the many health benefits of the vitamin, but these are so numerous and important that it is probably wise to regard the RDA as the minimum necessary for the avoidance of deficiency. Supplementing to a total intake of 5,000 IU should ensure optimum benefits and levels of up to 10,000 should do no harm in most cases.

The one very important exception to this is pregnant women and those seeking to become pregnant, for whom intakes of 5,000 IU and above may increase the risk of birth defects. Women in these categories should supplement only with the much less potent betacarotene, if at all, and should also avoid the high retinol foods identified above.

Some caution is required for all people, however, because being fat soluble, vitamin A is stored in the liver and can in rare instances build up to levels which may give rise to problems. Of course this characteristic of the vitamin is not confined to the human liver, and writers on this subject are fond of pointing out by way of example, apparently in all seriousness, that polar bear liver is likely to contain a concentration of vitamin A which is toxic to humans, and should therefore be avoided as a foodstuff.

At the risk of stating the obvious, that’s unlikely to present any significant practical difficulties for most of us. And with the exception of pregnancy, the potentially serious consequences of outright vitamin A toxicity seem generally to have arisen only from very large doses.

So exercise a little common sense, and if you can just manage to steer clear of that polar bear liver you should be able to enjoy the benefits of vitamin A without any problems.

 

Liquid Vitamins Vs Chewable Vitamins

Vitamins and supplements are very popular, especially for those who have active lifestyles and find it difficult to consume the necessary vitamins and minerals they need from the proper meals. Therefore, those with busy lifestyles turn to vitamins and supplements to give their bodies what it needs to carry out day to day activities. Even though you should never replace food with vitamins, vitamins can help you to get the nutrients and minerals you need on a daily basis.

The main reason why liquid vitamins are more effective than pills and tablets is due to the nature of their liquid base. With the vitamins being liquid, they are easier for the body to digest and easily absorbed into the digestive tract as well. Chewable tablets and pills will pass through the body in hard form, making them hard to digest. Liquid is always digested when it passes through, so it will go through your body quicker and take effect faster.

Due to the body having to work less to break down and absorb liquid vitamins, they will pass through the body much faster.

The nutrients and minerals contained in liquid vitamins will reach vital areas faster through the bloodstream, and they are easier to use by the most important organs in your body that need them the most. Liquid is also easy to swallow as well, as you can add the liquid vitamins to your favorite juice or just take it right out of the bottle if you prefer.

With pills or chewable vitamins, the majority of the nutrients and minerals that are contained in the vitamins aren’t normally broken down in the digestive system. With these types of vitamins being in hard form, they are harder for the body to pass at the most crucial moments, where the body needs to have nutrients and minerals. Unless you completely chew up the vitamin, it can stay in hard form until it passes through when you go to the bathroom. If this happens, you are normally just wasting the vitamin as it doesn’t have a chance to get into the bloodstream.

Liquid vitamins have proven themselves to be the best way to get the minerals and nutrients your body needs.

As more and more people discover the benefits of liquid vitamins and how easy they are to digest, they make the switch. Liquid vitamins are far superior to tablets and pills, simply because it tastes better, it’s easier to digest, and it travels through the body faster. You can find many different flavors and types of liquid vitamin supplements at your local nutrition store, or get online and order what you need there. Either way you go – you’ll find liquid vitamins to be the ideal way to get the nutrients you need for you body on a daily basis.

 

Great Benefits of Fish Oil

Some experts believe that taking fish oil (in any form) can help regulate cholesterol in the body,[attribution needed] because fish oil has high levels of omega-3 fatty acids. The regulation occurs through effects of the EPA and DHA constituents on Peroxisome proliferator-activated receptor alpha (PPARĪ±). Besides cholesterol regulation, benefits include anti-inflammatory properties and positive effects on body composition. However, the preferred source of Omega 3 should be from the fish’s body, not the liver.

Fish oils are fascinating nutrients. Almost every aspect of our health, physical and mental, is related to the types of fatty acids that make up our cells and tissue, including vision. And it appears that most of us are not ingesting the right kind of fatty acids, the ones found in fish and fish oils. I have discovered that fish oils supplements help eyesight. I have also discovered a combination of herbs and nutrients that improve eyesight within hours. See below. Fish oils are also beneficial for mental health and sexuality.

1. Fish oil prevents heart attack – Dr Alexander Leaf and colleagues at Harvard Medical School found that eating oily fish like salmon or tuna at least twice a week could prevent a heart attack.

2. Fish oil protects against heart disease and stroke – Researchers at Southampton University found that omega-3 fish oil stops the build up of fatty deposits in the arteries, protecting against heart disease and stroke.

3. Reduction of Breast, Colon and Prostate Cancer. And finally, omega 3 fish oil has been shown to help prevent three of the most common forms of cancer – breast, colon and prostate. Science tells us that omega 3s accomplish this in three ways. They stop the alteration from a normal healthy cell to a cancerous mass, inhibiting unwanted cellular growth and causing apoptosis, or cellular death, of cancer cells.

4. Fish oil prevents mothers from giving birth to very small babies – The University of Bristol research team found that a mother-to-be who eats fish during the later stages of pregnancy is less likely to have a very small baby.

5. Stopping the buildup of fatty deposits (triglycerides) in the arteries.

6. Fish oil helps with prostate cancer – The Paterson Institute researchers found that a diet rich in a fat found in oily fish and some seeds may protect men with prostate cancer from developing a more aggressive form.

7. Fish oil reduces the growth of breast cancer – Researchers from Indiana University found that when mixing compounds from omega-3 fatty acids with the anaesthetic propofol, together they appeared to reduce the growth of breast cancer cells.

8. Fish oil reduces inflammation – The researchers from Harvard Medical School and Brigham and Women’s Hospital found that a diet high in oily fish like salmon and mackerel may help improve inflammatory conditions such as arthritis; the oily fish diet worked best when combined with low aspirin doses.

9. Protection from Stroke and Heart Attack. When plaque builds up on arterial walls and then breaks loose, it causes what’s known as a thrombosis, which is a fancy way of saying clot. If a clot gets stuck in the brain, it causes a stroke and when it plugs an artery, it causes a heart attack. Research shows omega 3 fatty acids break up clots before they can cause any damage.

10. Fish oils may be helpful to people with lupus since fish oils have anti-inflammatory properties.

11. Fish oil betters brain and visual development in children – Bristol University researchers found that a mother-to-be who eats oily fish is more likely to have children with better brain and vision developments.

12. Fish oil has also been used to treat conditions such as depression, eczema, IBD, macular degeneration and arthritis. Fish oil benefits the heart significantly, as well as the rest of the body.

How much fish oil should adults take?

A good dose for adults is roughly ~6 grams of salmon oil per day with food.
Should everyone take fish oil?

Generally yes. In a minority of cases some individuals feel strange on fish oil and do better on other oil types.

Although you can get the benefits of fish oil from eating cold water fish such as salmon or cod, there is always the danger of mercury contamination as well as other toxins. This is why pregnant women and young children are advised against eating fish.
