In May 2017, new data linking vitamin D and fertility was presented at the European Congress of Endocrinology (ECE) in Lisbon. The new findings contribute to our understanding of vitamin D’s impact on male testosterone levels and of our knowledge about whether vitamin D supplements may actually improve fertility in both sexes. Involuntary infertility, a widespread problem, may be a result of many factors, but if the reason is a vitamin D deficiency, it is easy to treat with increased exposure to sunlight and the use of supplements to keep vitamin D levels optimal all year round.

For decades, medical science has claimed that fish oil increases the risk of bleeding and has therefore warned against taking fish oil supplements prior to surgery. A large, systematic review of studies that is now published in the Danish Medical Journal shows that fish oil supplements do prevent blood platelets from aggregating, but this biochemical effect is not associated with increased bleeding risk in connection with surgery. It is therefore safe to continue taking supplements – and eating oily fish.

It is no coincidence that sclerosis is more prevalent at the northern latitudes. A major factor is lack of vitamin D, a nutrient that we only synthesize from sunlight during the summer. A new study published in the scientific journal Neurology shows that the risk increases even more if people are overweight, and children are particularly vulnerable. As part of the strategy for preventing sclerosis, we must pay more attention to weight management and make sure to get plenty of vitamin D all year round and throughout life. Furthermore, various campaigns that warn against sun exposure and recommend the use of sunscreen should at the same time advise children and adults how to get enough vitamin D from other sources.

Vitamin B3 (niacin) is important for our nervous system and mental balance. Epidemiological studies have shown that vitamin B3-deficient diets are linked to aggression, and increased prevalence of homicide and suicide among people and cannibalism among animals. More than 60 years ago, Dr. Abram Hoffer observed that high doses of vitamin B3 had a positive effect on schizophrenia, and later studies have shown similar results. Lack of vitamin B3 may be caused by genetic, dietary, or environmental factors that are easy to correct.

Vitamin B12 is important for the development of the brain, and young children with low levels of the nutrient are challenged when it comes to solving cognitive tests such as puzzles, letter recognition, and the ability to understand the feelings of other children. Vitamin B12-deficient children are therefore more vulnerable and generally have a more difficult start in life. Researchers have demonstrated this in a study that is published in the American Journal of Clinical Nutrition.

Psoriasis patients are generally interested in their diet and how it affects their disease. So far, there has not been much data so far to support a connection, but a new American study has mapped out the exact effects of regular diet habits and various supplements.

Schizophrenia is a serious psychotic condition with delusions and hallucinations, which can be very taxing for the sufferer as well as for the rest of the family. Most people experience a slow and gradual worsening of the brain ailment, and the disease may even spread to other organs. On average, people who suffer from schizophrenia die 10 years earlier than the general population, which is why it is vital to prevent the disease or ameliorate its symptoms. Scientists have discovered that supplementing with omega-3 fatty acids has a positive effect for several reasons.

If you find it difficult to control your desire for chocolate, candy, cake, soft beverages, and stimulants in general, and if you struggle with tiredness, overweight, and other problems related to unstable blood sugar, you will be pleased to learn that Danish researchers have revealed that a hormone produced by the liver controls our desire for sweets and stimulants. The scientists therefore see a potential in developing a new type of medicine that can control the need for sugar. However, it is also possible to control your sugar cravings by means of simple dietary changes combined with supplements of chromium, a mineral that increases insulin sensitivity.

We all are exposed to some degree of air pollution, but a new study shows that supplements of vitamin E and omega-3 fatty acids work like a dynamic duo with a highly protective effect on cells and the cardiovascular system. This is because vitamin E is a powerful antioxidant and omega-3 fatty acids have anti-inflammatory properties.

- that is involved in atherosclerosis, rheumatism, and most other chronic diseases

Scientists from Mexico, Iran, and Australia have gathered data from several studies and focused on a certain protein that is a marker of inflammation in the body. According to the researchers, magnesium supplements can significantly reduce levels of this protein. Because magnesium deficiencies are widespread, it seems obvious to administer magnesium supplements as part of the anti-inflammatory treatment, especially because inflammation is not always easy to detect and may even set the stage for a host of other chronic diseases. It is important, however, to balance magnesium with calcium. This is a general rule both in the prevention and treatment of all chronic inflammatory conditions.

- but only few preparations work

The plant extract Ginkgo biloba contains some biologically active compounds that improve circulation through blood-thinning and vessel-dilating actions. However, a study of 29 different Ginkgo biloba preparations revealed that only 10% of the investigated products actually contained Ginkgo extract. You can avoid this problem by only using Ginkgo biloba in the form of natural remedies, because they are registered as pharmaceutical drugs.
