– and why it is vital to get the exact right amount!

All our cells contain different selenium compounds that support a number of vital functions, and which have several cancer-fighting mechanisms. As an antioxidant, selenium prevents iron from developing some of the most harmful free radicals that can damage cellular DNA and lead to uncontrolled cell division. This is why a selenium deficiency combined with excess iron is a lethal cocktail. Although iron is essential, it is vital that we do not get too much. It is also important to get plenty of selenium from food and/or supplements and in a form that the body can absorb and utilize in each and every cell in order to be properly protected against cancerous substances.

Nothing beats a good night’s sleep. Still, sleep disturbances are widespread, and surprisingly many people struggle through the day, trying to survive on far too much coffee and other stimulants – and they cannot do anything about the problem. It turns out that many vegetarians, users of birth control pills, older people, and diabetics suffer from sleep problems because they lack vitamin B12. A vitamin B12 deficiency may also affect the nervous system and memory so it is vital to get enough of this nutrient.

– but will enrichment do the trick?

Even minor zinc deficiencies may cause poor digestion, infections, skin problems, and fatigue – and many other diseases may occur along the way. A new study shows that a diet with as little as four extra mg of zinc daily may strengthen cellular DNA and help protect the body. The four milligrams of zinc are about the same as populations with deficiency symptoms can get by eating zinc-enriched wheat and rice.

A team of scientists from Oregon State University in the United States has managed to explain why lack of vitamin E may cause neurological damage to the developing fetus, and why it increases the risk of spontaneous miscarriage. Their study is published in the science journal Free Radical Biology and Medicine and here, the scientists underline how important it is for both women who are pregnant and those plan pregnancy to get enough vitamin E.

It came as good news for vegetarians, vegans and sclerosis sufferers when Danish health authorities allowed strong vitamin B12 preparations on the market some years ago. It was also positive that the active methylated form of vitamin B12 was added to the list of approved ingredients.

Cancer researchers from the University of Iowa in the United States have finally clarified how extremely high doses of vitamin C given as infusions are able to kill cancer cells. It turns out that the low levels of the enzyme, catalase, in cancer cells make them vulnerable to vitamin C’s ability to generate free radicals. That way, vitamin C works like a type of chemotherapy, while, at the same time, stimulating normal activity in healthy cells. We are dealing with a treatment that is virtually devoid of side effects.

- and for the prevention of allergies and inflammation

Every day, the intestinal immune system has to defend itself against hordes of microbes and toxins. If it fails to function optimally, there is an increased risk of infections, allergies, and inflammatory diseases. More and more research reveals that essential nutrients help to control the intestinal immune defense. Also, new research shows how important a well-functioning immune system is for our digestion and health in general. This article takes a closer look at the vitamins that are known to be particularly important for the intestinal immune system. Another thing that is vital is to have adequate amounts of gastric juice.

 – especially among those with metabolic syndrome, an early stage of type-2 diabetes

Millions of people who are overweight suffer from blood sugar imbalances and metabolic syndrome – often without being aware of it. A study shows that people with metabolic syndrome are severely vitamin E-deficient. This poses a serious threat to their health, as vitamin E is important for the liver, the cardiovascular system, the nervous system, and the body’s ability to protect its cells against oxidative stress and carcinogenic substances. The study, which is published in the American Journal of Clinical Nutrition, reveals that normal measurements of a person’s vitamin E status are misleading.

We all know the importance of eating a healthy diet, exercising, getting sufficient sleep, and sunbathing with caution. Still, life is not always that simple, and even if we stick with the official guidelines for healthy living, it can often be challenging to get adequate amounts of the essential nutrients. Nonetheless, supplements are useful as compensation for these shortcomings. In fact, the use of such products can be compared with plant fertilizers that make plants look healthy, flourish and thrive.

There is widespread potassium deficiency, and it is common knowledge that an increased potassium intake lowers the risk of hypertension, which is the leading cause of stroke, cardiovascular disease, and early death. However, not many people know that potassium has a vital impact on blood sugar levels and the prevention of diabetes, just as it counteracts side effects of diuretics. The question is how much potassium do we need – and how does the balance between potassium and sodium (salt) affect our health?

- and you also need magnesium for your bones

It has been discussed whether it is calcium or vitamin D that improves women’s cholesterol balance. Earlier studies of women who use combined supplements have not been able to determine whether the positive effect is due to calcium or vitamin D. However, a study from Women’s Health Initiative (WHI) reveals that the effect is down to vitamin D. If you want strong bones and a healthy cardiovascular system, it is a good idea to combine both calcium and vitamin D with magnesium.

- that cause many sick days and even deaths

Vitamin D supplements prevent colds, influenza, and intercurrent complications. This was seen in a large meta-analysis emphasizing that vitamin D is not only important for bone health but also for the immune system, which may require larger quantities. Because many old people or weakened individuals die of pneumonia, supplementing with vitamin D may potentially save millions of lives.
