A groundbreaking new Australian study shows that something as simple as a vitamin B3 supplement can prevent miscarriages and congenital defects of the heart and other organs. This is because the nutrient is involved in the body’s production of NAD, a molecule of vital importance to fetal development. Because vitamin B3 deficiencies are common, it is important to have increased focus on the vitamin, especially in connection with pregnancy.

An international team of researchers has just completed a huge study of the possible link between maternal DNA, selenium deficiency, and preterm labor. Earlier studies have shown that women with low blood selenium have an increased risk of preterm birth and that selenium supplementation may lower that risk. A problem in that respect is that climate changes and soil depletion may increase the risk of selenium deficiencies, especially in Europe.

A new study shows that vitamin B3 has the potential to prevent skin cancer and melanoma, which is the most dangerous type of skin cancer. Apparently, vitamin B3 can boost the body’s repair of DNA damage caused by UV radiation from the sun or sunbeds.

According to a study from Ohio State University, Columbus, USA, people suffering from dry eyes may find relief by consuming more oily fish or taking a fish oil supplement.

Vitamin D deficiencies are widespread among people who are overweight or have type-2 diabetes. However, researchers have not been able to explain the exact link. A study done by researchers from Baylor College of Medicine, Houston, Texas, suggests that it has something to do with vitamin D’s role in the brain, where the nutrient helps control both weight and blood sugar levels.

The brain normally only uses blood sugar in the form of glucose. However, people suffering from insulin resistance have impaired cellular uptake of blood sugar, causing an energy shortage of the brain. According to a recent Israeli study, insulin resistance may speed up impairment of the cognitive functions that include the ability to think, speak, and solve problems. Because insulin resistance is an early stage of type-2 diabetes that spreads like an epidemic, there is every reason in the world to start preventing or treating this condition. A few dietary adjustments combined with a blood sugar-regulating trace element may do the trick.

Approximately one in seven couple is childless. Although there can be many underlying causes, poor sperm quality is an increasing problem. It may be caused by a lack of certain nutrients and exposure to different environmental factors, but, fortunately, it possible to improve sperm quality and increase the chances of conception by means of relevant dietary adjustments and the use of specific supplements. New research shows that epigenetic factors (factors that affect the environment of the sperm cell) determine sperm health and are therefore crucial for activating the genes of the sperm cell so the fetus can develop.

Many older people sleep poorly and tend to have elevated blood pressure. Luckily, supplementation with melatonin seems to correct both problems. Melatonin can even improve sleep in people who take beta-blockers for high blood pressure. So what is melatonin, and why is this substance particularly useful for older people?

Vitamin K2 clears calcium from the bloodstream and embeds it in bone tissue. Therefore, vitamin K2 is of vital importance to bone building and the prevention of atherosclerosis. Medical News Bulletin has placed even more focus on vitamin K2’s role in maintaining strong bones and reducing the risk of a fracture. The question is, how much vitamin K2 do we really need for optimal bone health, and why is it important to know the difference between vitamin K1 and vitamin K2?
