The trouble with this dietary supplement is that it contains way too much vitamin a, which may be bad for bones. Scientists have reported that high intake of vitamin a from cod liver oil in Sweden and Norway is associated with weaker bones, osteoporosis, and an increased risk of hip fracture.1 To get around this problem, pharmaceutical-grade fish oil might be very helpful. Barry Sears, PhD (of Zone Diet fame), recommends between 3 and 8 grams total of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) daily to calm inflammation.120 According to Dr.

It has been said that many sudden deaths following vaccination can be prevented by sufficient vitamin C and vitamin a reserves (or supplementation), but we should probably take a good look at magnesium deficiency as a crucial factor in sudden death. In adults it has been seen how high levels of mercury in the heart becomes dangerous. Since deficient magnesium and high levels of mercury are related, childhood vaccines containing thi-merosal would be especially dangerous to administer in children deficient in magnesium. According to Dr.

Importantly, zinc is vital for the metabolism of vitamin a. A paper by Dr. Mei and colleagues at the Anhui Medical University, Hefei, China, suggests that some aspects of immune function can be enhanced by treatment with zinc. The authors state that it would be "reasonable to expect that zinc is instrumental in restoring failing immuno-competence of cancer patients. Mei studied the influence of zinc and selenium-zinc upon the immune function (T-cells, granulocytes and NK cells) of cancer patients. The results showed that immune response was strengthened.

Adequacy of milk intake has been associated with adequacy of calcium potassium, magnesium, zinc, iron, riboflavin, vitamin a, folate, and vitamin D for children [46]. Many calcium-fortified foods are on the market that could theoretically be used to provide the requirements for this nutrient. Gao et al. [47] evaluated the ability of dairy-free diets to meet calcium intake while meeting other nutrient requirements using diets in American children aged 9 to 18 years for those participants in NHANES 2001-2002 who reported no intake of dairy.

Two patients with advanced epithelial ovarian carcinoma (stage IIIC) received antioxidant therapy (1200 IU vitamin E, 300 mg coenzyme Q]0, 9000 mg vitamin C, 25 mg mixed carotenoids, and 10,000 IU vitamin a) before conventional chemotherapy and 60 g ascorbic acid twice weekly at the end of therapy. Both women had normal CA-125 levels and remained disease-free more than 3 years after initial diagnosis [120].

The role of vitamin a in preventing night blindness and xerophthalmia, which remain common problems in developing countries, has been widely discussed [If Food shortages, as occurred in Cuba in 1991 to 1994 and among the allied prisoners of World War II, or chronic alcohol use can result in a condition broadly referred to as nutritional amblyopia, which results in blurred vision and reduced visual acuity (recently discussed [2]). This may be the result of poor intake and absorption of B vitamins or antioxidants, alcohol and tobacco toxicity, or a combination of these factors.

Persimmons are an excellent source of vitamin a, a good source of vitamin C, and rich in fiber. They contain a variety of phytochemical antioxidants such as proanthocyanidin, epicatechin, gallic, and p-coumaric acids. One study found persimmons to be higher in soluble and insoluble dietary fibers, total phenols, and many minerals than apples.

Look for antioxidants such as vitamin a, vitamin C, vitamin E, beta-carotene, lycopene, lutein, bioflavanoids, resveratrol, zinc, and selenium. You'll want a formulation that includes the full spectrum of B vitamins, including the activated forms of B2 and Bfi (riboflavin-5 -phosphate and pyridoxal-5 -phosphate, respectively). You'll also want a multivitamin formula that includes vitamin D3, and make sure the vitamin E is in the form of d-alpha-tocopherol. Avoid the "dl" form, which is synthetic. You'll want a high-potency vitamin C (about 1,000 mg) provided by ascorbic acid.

It contains more conjugated linoleic acid (a component of fat that boosts fat-burning and the buildup of lean muscle mass), more omega-3 fats, and vitamin a. In addition, it has less fat, cholesterol, and calories. Farms that specialize in grass-fed cattle are also better for the environment. Cattle allowed to graze on large areas of land are easier on the land and pollute less than do factory farm animals.

This is especially true if there is already a chronic disease state or if we are not taking in essential nutrients such as zinc, vitamin a, and selenium, which is necessary for one particular detoxification pathway. Most of us have hundreds of toxins stored in our bodies, all of which strain the natural states of our organs and tissues. The Seven Channels of Elimination 1. Lungs: The lungs dispel toxins with every exhalation. Chief among these toxins is carbon dioxide, a by-product of respiration, the body's release of energy.

Taste disorders can be important clues to a vitamin a or B, (niacin) deficiency as well. Less commonly, they may signal diabetes, multiple sclerosis, liver disease, AIDS, or cancer. Any loss of taste, even a partial one, can have serious repercussions. People with diminished taste often oversalt and oversweeten their food, which can be dangerous if they suffer from hypertension or diabetes. For those of us who have a taste for the good life, life without the richness and variety of food may seem hardly worth living. Unfortunately, people who lose their sense of taste can become depressed.

In fact, if anything, there was a slight increase in mortality, although only about 2%, which is less than that for vitamin a and beta-carotene. One study by Waters and colleagues of vitamin E combined with vitamin C showed that vitamins actually accelerated the progression of thickening of the coronary arteries and doubled the risk of dying of heart disease.

Indeed, an excess of certain medicines or even essential vitamins and minerals (especially vitamin a and selenium) can cause your hair to fall out. High foreheads were considered a sign of beauty in Elizabethan England. Fashionable ladies shaved or plucked their front hairs to achieve this look.

But if your skin looks more orange than yellow, it may merely be a sign of carotenemia (see Chapter 7), a usually benign condition resulting from consuming too much beta-carotene or vitamin a, either from supplements or from foods such as carrots. In some cases, yellow skin can be a sign of a hereditary, benign form of jaundice called Gilbert's syndrome. (See Chapter 2.) However, it's warning sign For some people the combination of wearing perfume or cologne and going out in the sun can cause skin discoloration, which can be permanent.

I don't believe there's a very high risk at all of vitamin a toxicity, even if you're chowing down on very large doses of spirulina on a regular basis. And I submit my own experience as a demonstration of that -- I consume large amounts of spirulina, perhaps more than any person I know, and yet I don't show any of the symptoms of vitamin a toxicity at all. But just to be safe, always work with your health care provider before starting any nutritional supplements, including spirulina.

The Vitamin D Cure James Dowd and Diane Stafford See book keywords and concepts

We aren't just talking a seat on the front row—vitamin D and its partners vitamin a and DHA are conducting the orchestra. Most people know that vitamin D is important in absorbing calcium from food. D's importance in the formation of bone and teeth in children is also widely known. In addition, vitamin D helps you build muscle and protects your brain cells from injury or inflammation. Vitamin D slows the growth of cells—a factor that may well reduce your risk of most cancers by as much as 50 percent.

Dizziness Keep in mind, too, that chronic vitamin a toxicity can cause birth defects, liver abnormalities, osteoporosis, and central nervous system disorders, so this isn't a vitamin you can take lightly. Many people worry about taking too much vitamin D, but it's very hard to overdose on vitamin D. Toxicity is highly unlikely at a vitamin D level of less than 100 and at a vitamin D intake of less than 60 IU per pound, or roughly 10,000 IU a day. You can spot toxic vitamin D levels by the following symptoms: ?Frequent urination ?Constipation ?Nausea ?Weakness ?Vomiting ?Weight loss ?

Beta-carotene and alpha-carotene can be turned into vitamin a, which is important for the health of the eyes and the nervous system. Antioxidants naturally complement one another, and taking one by itself in high doses can actually increase free-radical damage. Your best bet for restoring levels of carotenes is to boost your fruit and vegetable intake—which could help get rid of your gout, too! Put as many naturally bright colors into each meal and snack as you can, and augment with concentrated green food supplements as powders or capsules. ?Folic acid: 400 meg daily. ?

Based on the results of the studies I've reviewed, I recommend that you not take any amount of vitamin a or beta-carotene in the form of fortified foods like breakfast cereal or vitamins and supplements. VITAMIN C Vitamin C is a water-soluble vitamin that is required for the growth and repair of many tissues of the body. As I discussed earlier, from the late 1960s until just before his death in 1994, Nobel Prize-winning scientist Linus Pauling was convinced that megadoses of vitamin C were not only good for you in general but specifically were able to prevent colds.

There is something awfully seductive about the idea that some extra vitamin a every morning or a dose of ginseng tea twice a day can somehow change your life for the better, particularly for a country full of optimists. This is magical thinking at best, since there is little evidence that vitamins and supplements taken in a pill form are good for our health. In fact, scientific evidence shows that some vitamins are bad for us, increasing the risk of cancer and heart disease, hip fracture, and other ailments. Others, taken in high doses, can be toxic.

Accutane belongs to the class of compounds called retinoids, which includes the active form of vitamin a. Originally approved as a second-line treatment for cystic and nodular acne, Accutane inhibits sebaceous-gland secretions. Since its approval for the indication of cystic acne by the FDA in 1982, Accutane, manufactured by the Swiss-based company Roche, has been prescribed for 2 million patients in the U.S. and more than 8 million patients worldwide.

Looking at all these studies together, there is an increased risk of heart disease with vitamin a and beta-carotene associated with a 29% increase in mortality when the two are combined.36 Trials for vitamin E have not shown that it prevents heart disease,37"40 with the exception of one study showing a modest decrease in heart attacks.41 Other studies like ATBC showed an increase in strokes. When Vivekananthan and colleagues combined data from several previously published studies, no heart-protective effects of vitamin E were shown.
