The risk of dementia and neurological disorders increases with age. Diet plays an important role and it is assumed that the widespread lack of vitamin K2 is particularly relevant. In order to test this hypothesis, a group of scientists measured levels of vitamin K2 in the brains of deceased seniors. They found significantly fewer cases of cognitive decline, dementia, and Alzheimer’s disease in brains with higher K2 levels. This has something to do with the fact that vitamin K2 counteracts atherosclerosis, accumulation of harmful protein, and brain inflammation. The study is published in the journal Alzheimer’s & Dementia and sheds a whole new light on vitamin K’s potential role in brain health and the importance of getting enough of this nutrient.

Around one billion people worldwide are believed to lack vitamin D. This gives cause for concern when it comes to public health, also with regard to pregnant women and their children. Several studies link vitamin D deficiency to a number of different pregnancy-related complications such as preeclampsia, increased risk of preterm delivery, and the need for a Caesarean section. There is also a risk of low birth weight, weak bones, and later development of bronchitis, asthma, type 1 diabetes, sclerosis, and autism, according to a review article published in Nutrients. The authors believe it is necessary to give supplements to help correct vitamin D deficiencies in the expecting mothers and even in the children after birth to prevent many of the diseases and complications linked to low vitamin D status.

Colorectal cancer is one of the most common cancer types. Although the diet is of huge importance, the understanding of minerals and their interactions and preventative effect is limited. Earlier studies have shown that calcium and selenium have protective roles. It also looks as if having more selenium in the blood can improve the effect of calcium. This was demonstrated in a new Polish study that is published in BMC Nutrition. The scientists point out that there is widespread selenium deficiency in Europe and that supplementation may be needed.

Congenital heart defects are the most common birth defect on a global scale. The condition is associated with a number of different complications and even comes with an increased risk of infant death. Maternal nutritional status is vital for the development of the fetus, and a team of Chinese scientists has looked closer at how selenium, zinc, and copper affect the development of the disease. They found that a relatively high intake of selenium and zinc lowers the risk of congenital heart defects. Therefore, the scientists call for increased focus on these two minerals during pregnancy and advocate the use of supplements.

Magnesium is involved in hundreds of different enzyme processes in the body, including ones that are important for our digestion. Magnesium is found in various compounds, and it has been known for a long time that magnesium oxide has a laxative effect. Because this particular magnesium compound only works locally in the intestine, it is difficult for the body to absorb it and is therefore not suited for supplementation if you want to correct a magnesium deficiency. In this article, we will look closer at dietary magnesium, the absorbability of different magnesium compounds, and magnesium’s role in our digestion and nervous system, which are closely related. We will also look at other symptoms that may be caused by a magnesium deficiency.

Many people unwittingly suffer from a disease called non-alcoholic fatty liver disease, which is related to overweight and diabetes. The diet plays a major role, and a Chinese study shows that vitamin B12 is of particular importance. The scientists believe that the body’s vitamin B12 metabolism holds a therapeutic potential in relation to detecting and treating the disease and the complications that follow in the wake of it.

There is a link between the widespread problems with vitamin D deficiency and the growing prevalence of Parkinson’s disease. In a review article that is published in the science journal Nutrients, a group of scientists look at vitamin D’s role in the nervous system and the brain. It is relevant to use supplements that optimize blood levels of vitamin D as part of the prevention and treatment of this disease.

Some people prefer to eat raw vegetables in combination with meat or fish or as entirely raw vegan diets. They believe it is healthier and delivers more energy. But the truth is that some vegetables are healthier and provide more antioxidants if you heat them. That’s the case with tomatoes, bell pepper, carrots, spinach, and mushrooms. And remember that raw mushrooms contain toxins that are broken down by cooking.

Over the past decades, the number of children and teenagers with ADHD has skyrocketed, and the diet has a lot to say. According to a new American-Canadian study, supplementing with all the essential vitamins and minerals can improve young ADHD sufferers’ mood, emotional disturbances, and ability to concentrate. The supplements can even stimulate their growth.

It is vital to take good care of your eyes throughout life to maintain good vision. Our eyes need a number of different vitamins, minerals, and fatty acids that are important for cellular function and for protecting against oxidative stress. In this article, you can read more about vitamin A, vitamin C, vitamin E, B vitamins, zinc, selenium, omega-3 fatty acids, and Q10 and their vital role in maintaining healthy vision. We will also look at certain antioxidants that are found in eggs, salmon, spinach, broccoli, red bell pepper, and blueberries.

- and normal B12 supplements are often not enough

Vitamin B12 is only found in animal sources, which is why vegetarians and vegans risk getting too little. If children lack vitamin B12 it may result in underdeveloped motor skills and anemia, according to a study from Burkina Faso that is conducted in collaboration with the University of Copenhagen and Doctors Without Borders (Médecins sans Frontières). The scientists point out that vitamin B12 deficiencies are a big and overlooked problem and that normal B12 supplements are often not enough so new solutions are required.

Lack of vitamin B12 is known to cause fatigue, poor memory, cognitive impairment, and hippocampal atrophy. Supplementation with B12, on the other hand, can improve cognitive functions, according to a study that is published in Nutrients. The problem is that the signs of cognitive disturbance are insidious and therefore not automatically associated with a simple nutrient deficiency that is often a result of ageing, vegetarian diets, low stomach acid, or diabetes medication.
