Risks and Benefits of Cod Liver Oil

There are health benefits of cod liver oil and there are drawbacks. Cod liver oil benefits may not outweigh the risks. The primary benefit of cod liver oil is related to its omega-3 content, but fish oils derived from the flesh of fish, rather than the liver, provide that benefit without the risks.

Nutritional Vitamin Supplements

The health benefits of cod liver oil are related, primarily to omega-3 fatty acids. These are essential for the healthy function of the brain, the heart, the joints, the digestive system and many other systems of the body. Another benefit of cod liver oil is related to its vitamin E content, which helps the body process the fatty acids, is an essential antioxidant and promotes the health of the skin and the hair.

Omega-3 Fatty Acids/Benefits of Cod Liver Oil

Omega-3s are essential to human health, cannot be produced inside the body, and so, must be obtained from food or through supplementation. The best know source of omega-3 fatty acids is fish. Some fish contain more omega 3s than others.

There are two types of omega-3 fatty acids that have been identified as essential for human health. They are Docosahexaenoic Acid or DHA and Eicosapentaenoic Acid or EPA. These are found primarily in fish. The body can convert another omega-3 fatty acid, known as Alpha-linolenic acid or ALA, to DHA and EPA, but the process is relatively inefficient. It is believed that one would have to consume a great deal of ALA in order to get the health benefits provided by DHA and EPA.

The omega-3 found in flax seed oil is ALA. And some believe that flax seed oil can provide cod liver oil benefits, without the risks, but this is debatable. Although there are no risks associated with flax seed oil, it is unknown if ALA provides the same health benefits as DHA and EPA.

The Risks

Cod liver oil contains large amounts of vitamin A and vitamin D and may contain contaminants such as mercury and pesticides. The body needs adequate amounts of vitamin A, but large amounts can be toxic. Vitamin D is not commonly found in natural foods, but many processed foods are fortified with vitamin D to ensure good nutrition.

At one time the benefits of cod liver oil were believed to be associated with its vitamin A and D content. This was before omega-3 fatty acids had been identified and before food fortification was a common practice. It was also before taking daily multi-vitamins became a common practice and before industrial pollutants had contaminated our oceans.

Vitamin D

While no tolerable upper limit for vitamin D consumption has been established, adequate intake for adults, under the age of 50, and children is believed to be around 200 units per day. Adults over 50 should increase consumption to 400 units per day for men and 600 units per day for women. Vitamin D is necessary for the body to process calcium and is therefore a factor in preventing osteoporosis and maintaining bone health. However, one of the popular cod liver oil products contains 4000 to 5000 units of vitamin D per teaspoon, more than anyone needs on a daily basis.

Vitamin A

A tolerable upper limit for vitamin A has been established. The maximum amount of vitamin A that a 25 year old man should consumer per day is 10,000 IU. Women should consume less than half that amount. Women who are pregnant should avoid dietary supplements that contain vitamin A because of the risk of birth defects. While vitamin A is necessary for fetal development and overall good health, it is stored in the fat cells and there is a great risk of over supplementation. Excess consumption of vitamin A is also believed to contribute to osteoporosis.

One of the popular cod liver oil products contains 4000-5000 IU of vitamin A, per teaspoon. When added to the amount that may be present in other dietary supplements, as well as the food that a person consumes per day, it will put most people over the safe upper limit for vitamin A. While the benefit of cod liver oil for supplying essential omega 3s is known, it is unknown if excess consumption of vitamin A will counteract those effects.

A better choice for vitamin A supplementation is beta carotene and other carotenoids. Present in the better daily dietary supplements, carotenoids are converted by the body to vitamin A on an as-needed basis and are not associated with the negative effects of "pre-formed" vitamin A. The only known side effect of excess consumption of carotenoids is a yellowing of the skin, called carotenosis, which is not dangerous, but may be undesirable.

Alternatives

Fish oil derived from the flesh of fish does not contain the vitamins A and D. Those vitamins are usually present in adequate amounts in daily multi-vitamins and fortified foods. Though extra vitamin D supplementation is often recommended for persons over the age of 50, it is not a benefit of cod liver oil and there are better choices for vitamin D supplementation.

From an environmental standpoint, over harvesting of the cod fish has led to the depletion of many populations. Farms affect the health of wild fish. The equipment used for harvesting damages the habitat of other water dwelling life forms. Although there are cod liver oil benefits, these health benefits can be obtained from other sources that do not cause damage to our environment.

You can get the health benefits of cod liver oil by taking fish oil supplements derived from the flesh, rather than the liver of fish. To learn more, please visit the Fish Oil Guide.

Vitamins And Supplements For Women

The Benefits of Multi Vitamin Supplements

The majority of people do not eat a sufficiently balanced diet to provide them with all of the vitamins that they require and this has led to a boom in the multi vitamin supplement industry. Multi vitamin supplements are available in a number of different forms, including tablets, gel capsules, and even liquids. Of course, the most obvious benefit to taking multi vitamin supplements is convenience. It is far easier for a person to take one dose of a multi vitamin supplement that contains all of the necessary vitamins compared to taking each one individually. This is especially the case for children as it can be difficult for them to take a large number of vitamin supplements but one dose of a multi vitamin supplement is far easier. Of course, a liquid multi vitamin supplement is the most suitable form for children; however, it also is beneficial to anyone who has difficulty taking supplements in traditional tablet form.

Nutritional Vitamin Supplements

The increase in the availability of multi vitamin supplements has led to a great variety in the brands and the actual content of the multi vitamin supplements. The names of some of the nutrients in these multi vitamin supplements can be a little bewildering and many people simply do not know which ones they require. To make the decision simpler there are now a number of multi vitamin supplements created for specific people. For example, there are multi vitamin supplements that are designed for children. These multi vitamin supplements contain the specific nutrients that children need for them to grow and develop properly. Pregnant women have unique nutrient requirements to ensure that their baby receives the necessary nutrients and there are multi vitamin supplements prepared for pregnant women. As we get older, we also have different nutrient requirements and multi vitamin supplements for the elderly are a popular product.

Nutritional Vitamin Supplements

It is important to consider the contents of any multi vitamin supplement before consuming too many. Some vitamins can be toxic if too much is absorbed and this can occur more easily with multi vitamin supplements as some of the content may be overlooked. The labeling of the actual percentage of the recommended daily allowance for each vitamin in a multi vitamin supplement should be clearly labeled and must be assessed before a person takes them. Always seek professional medical advice before taking any multi vitamin supplement if there is any doubt as to the benefits of the contents.

Nutritional Vitamin Supplements For High Stress and Physically Demanding Jobs

Most of us are living in a world that wants things done well and they want them done yesterday. This can put a lot of stress not only on your mind, but also your body. This article is written for both people that experience mental stress and those that experienced bodily stress.

Nutritional Vitamin Supplements

Nutritional vitamin supplements are very important for people that deal with stress on a daily basis. An unfortunate side effect of living under constant stress is that we tend to make poor food choices.

Nutritional Vitamin Supplements

This can lead to us skipping meals, eating unhealthy foods, drinking too much coffee, forgetting to drink water and all sorts of things that can add to nutritional deficiencies developing in your body. These can then lead to health problems down the road that you do not really have time or money to deal with.

Stress has also been found to significantly lower your immune system and bodily functions. This is where nutritional vitamin supplements come in, because they help provide the nutrients and building blocks that your body needs.

It has also been suggested that when you are under a lot of stress, and certainly physical stress, your body burns up more calories and requires a lot more nutrients. The truth is that most people are not getting anywhere near the nutrients that they need to remain healthy and well in the future.

Nutritional vitamin supplements can be a cheap way to ensure that your body is getting everything that it needs and can even help you relax and sleep better at night.

That's right. And the nutrients can give you more energy, improve your sleep, focus, memory, endurance, joints and stomach function, just to name a few effects that can happen.

You can start improving your health and help your body deal with stress a lot better by using high-quality nutritional vitamin supplements on a daily basis. It is affordable, it is easy and it works!

Nutritional Supplements: The Amazing Benefits of Vitamin E

The real benefits of Vitamin E may surprise you. First of all, what is Vitamin E? Vitamin E is not one nutrient but actually a group of eight nutrients known as tocopherols and tocotrienols. Each one of these groups is further broken down into alpha, beta, gamma and delta.

Nutritional Vitamin Supplements

Alpha-tocopherol is the most active and common form. This is the form most often found in vitamin supplements. This is also the only form of Vitamin E given an RDA (Recommended Daily Allowance). Folks who eat lots of fruits and vegetables and not much fat in their diet, probably don't get their RDA of alpha-tocopherol. Although alpha-tocopherol is the only Vitamin E component given an RDA, Gamma tocopherol is an important component as well.

Nutritional Vitamin Supplements

Vitamin E is an oil soluble vitamin and is stored by your body.

Benefits of Vitamin E and What It Does For You

What does Vitamin E do? Vitamin E acts as what's called an antioxidant. If you've read the section of my site on Health Supplements, you've no doubt read about what an antioxidant does. If not we can review quickly.

The cells of your body are under a lot of stress... oxidative stress. Oxidative stress occurs when highly unstable molecules called free radicals roam freely throughout your body. Free radicals are a by-product of not only the normal metabolic processes of your cells but also your environment. Things such as air pollution, sun exposure, ozone, nitrous oxide (from auto exhaust), cigarette smoke, alcohol consumption and so on.

Free radicals damage cell membranes and can result in changes to your cells that cause chronic diseases down the road. When your cells are being damaged by these free radicals, we say your cells are experiencing oxidative stress... and one of the benefits of Vitamin E is that it is an antioxidant and can significantly neutralize the free radicals that cause oxidative stress.

Benefits of Vitamin E and Heart Disease

Does Vitamin E aid in the prevention of heart disease? Well, the jury's still out on this one. Theoretically, the benefits of Vitamin E and its ability to significantly reduce the progression of atherosclerotic plaque (buildup on the inside of your artery walls), says yes, without a doubt.

An article in the Journal of the American Medical Association says so also. Using angiography, a correlation was found between taking Vitamin E supplements and a reduction in coronary artery atherosclerosis. Remember the above benefits of Vitamin E and how Vitamin E acts as an antioxidant? Well this is the same mechanism.

As Jeffrey Blumberg, Ph.D., F.A.C.N. of Tufts University, Boston, Massachusetts states "... surveys of over 200,000 people in different communities around the world have provided compelling evidence that diets high in vitamin E and/or use of vitamin E supplements reduce the risk of heart disease."

Dr. Blumberg stresses the importance of making the distinction between what he calls primary and secondary prevention. Primary prevention focuses on groups of healthy people and testing for new heart disease against different levels of Vitamin E intake over many years. Secondary prevention is taking groups of folks with existing heart disease and testing for a short duration using Vitamin E supplements along with placebos.

It is felt that the results of some secondary trials (the ones that claim no beneficial relationship between Vitamin E and heart disease) may be skewed by other factors in these heart patients such as smoking and diabetes. Also the drugs that these folks are taking along with the Vitamin E supplements could also affect the outcome of the research.

Concerning the benefits of Vitamin E, Dr. Blumberg goes on to state, "In thinking about the value of vitamin E supplementation, particularly in primary prevention, it is important to appreciate not only its potential benefit in heart disease but also in a variety of other chronic diseases associated with oxidative stress, including age-related macular degeneration, Alzheimer's disease, cancer, cataract, diabetes, Parkinson's disease, and rheumatoid arthritis."

Two other studies were reported on in the New England Journal of Medicine, the Nurses' Health Study and the Health Professionals Follow-up Study. These two studies followed thousands of women and men. The researchers found a significant reduction in heart disease of the folks taking Vitamin E supplements.

Benefits of Vitamin E and Alzheimer's

Can Vitamin E help cut your risk of developing Alzheimer's and other forms of dementia? New studies seem to suggest so. A recent report found in the Archives of Neurology showed that vitamin E taken together with Vitamin C had significant benefits.

The study's author, Peter Zandi PhD with Johns Hopkins Bloomberg School of Public Health stated, "These results are extremely exciting. Our findings suggest that vitamins E and C may offer protection against Alzheimer's disease when taken together in the higher doses available from individual supplements."

Another study also in the Archives of Neurology found that Vitamin E intake may slow the progression of cognitive decline as we grow older.

How does Vitamin E do this? Well, remember some of the benefits of Vitamin E cited above and how Vitamin E acts as an antioxidant? It is widely accepted that oxidative stress plays a role in the bringing about Alzheimer's. And by its antioxidant properties, Vitamin E is able to reduce this oxidative stress to the cells of your brain.

More Benefits of Vitamin E

Because of Vitamin E's antioxidant properties, it has been shown effective in helping treat osteoarthritis. Vitamin E has also shown to be helpful in preventing the formation of cataracts in your eyes. And it might also help in protecting your eyes against ARMD (age related macular degeneration) as you get older. ARMD is the major cause of blindness in the U.S.

In folks with diabetes, Vitamin E and other antioxidants have been effective in controlling blood sugar levels. There has also been found to be a relationship between low levels of Vitamin E and an increased risk of getting diabetes.

Vitamin E has also been found to reduce hot flashes for women going through menopause. And for male smokers, it has been shown to reduce the risk of prostate cancer.

Is Vitamin E Safe

A recent article appearing in the Council for Responsible Nutrition stated that Vitamin E is safe for folks in the general population at doses up to 1600 IU daily. With most of the daily doses you'll find out there being in the 200 - 400 IU range there should be no concern.
