Zinc supplements help your immune defense fight colds faster. This was seen in a Finnish meta-analysis where the majority of cold-ridden subjects who took supplements had recovered from their colds after five days, as opposed to those who did not take extra zinc. It is important to choose high-quality zinc supplements, which the body is able to absorb. Moreover, it is vital that the dose is sufficiently high during those days where the immune system actively fights the cold. High-dosed zinc supplementation is not encouraged for therapeutic use in other cases.

Research conducted over the past decades reveals that vitamin D plays a major role in the brain and nervous system. Now, a Finnish study published in Scientific Reports links vitamin D deficiencies to chronic headaches. Vitamin D deficiencies are becoming increasingly common because we spend too much time indoors. Even during the summer period, it seems that we are unable to produce enough vitamin D because of our exaggerated use of sun cream. Sunlight is the best source of vitamin D and it is therefore important that you expose yourself to enough sunlight to ensure adequate vitamin D synthesis (without getting burned.)

Zinc is a trace element that is necessary for around 300 enzymes that control the thyroid gland, fertility, the nervous system, the immune system, and a number of other functions. A team of scientists from the Technical University of Munich (TUM) has found a close link between the body’s zinc status and cardiac function. Although clinical zinc deficiencies are rare, short-term subclinical zinc deficiencies are more widespread than previously thought. Even a minor zinc deficiency may affect cardiac health and the countless enzyme processes that depend on the presence of zinc. Besides, zinc is a powerful antioxidant that protects cells against oxidative stress. There are many reasons why it is important to get enough of this nutrient.

The low spring sun and bright sunlight can trigger a migraine attack. According to a new report, migraines may also be caused by a lack of vitamin D, which are common during the spring period. The combination of both is therefore rather unfortunate. Earlier and more recent studies show that lack of Q10, magnesium, and B vitamins can also trigger migraines, a condition that makes life miserable for millions of people. What is important is to detect and avoid the things that seem to cause these attacks and, at the same time, make sure to compensate for the nutrients, which the cells are lacking, in order to help the nervous system, the hormone system, and the cardiovascular system function properly.

Omega-3 fatty acids are known to positively support chemotherapy by maintaining body weight and muscle mass. According to a new study that is published in the esteemed science journal, Nutrition, omega-3 supplements can even reduce different side effects of chemotherapy.

Lack of vitamin K2 increases your risk of stiff arteries and atherosclerosis, which is the leading cause of death worldwide. This was observed in two new studies, one that is published in the American Journal of Hypertension, the other in the journal Nephron. A third study that is published in Clinical Nutrition reveals that daily supplementation with vitamin K2 lowers the risk of early death caused by cardiovascular disease. Our diet used to provide substantially more vitamin K2 from fermented foods than now, and this type of food deserves a comeback. It is also important to know the difference between vitamin K1 and vitamin K2.

Mice that are genetically predisposed to glaucoma may avoid the eye disease if vitamin B3 is added to their drinking water. This was seen in a study that is published in the journal Science. The scientists behind the study say that vitamin B3 was surprisingly effective at eliminating the molecular alterations that normally occur with age-related glaucoma. They even see the vitamin as an inexpensive and potentially powerful tool for preventing this disease in the future. People should make sure to get plenty of vitamin B3, and it is also important to know that imbalanced diets, alcohol abuse, and the use of diuretics may easily result in a deficiency of the nutrient.

During spring and summer, many people suffer from allergy symptoms and hay fever because their immune system overreacts to airborne pollen. However, according to a new American study, it is possible that different lactic acid bacteria and bifidobacteria can help alleviate the symptoms. The explanation lies in our intestinal microflora and its importance for a properly functioning immune system.

Ageing processes are associated with loss of muscle mass and impaired physical performance, both of which tend to lower quality of life. It is commonly known that coenzyme Q10 plays a significant role in cellular energy turnover and protects against oxidative stress. Now, two independent cohort studies even show a relation between the body’s Q10 status and muscle strength. Earlier research even suggests that Q10 supplements may help older people develop more youthful muscle fibers. Individuals who take cholesterol-lowering statins are advised to take Q10 supplements.

According to a study that is published in PLoS Medicine’s Special Issue on Dementia shows that low levels of polyunsaturated fatty acids in the brain may speed up the development of Alzheimer’s disease. It is therefore vital not to shy away from dietary fats. What is important, however, is to consume unspoiled sources of omega-3 and omega-6 fatty acids in the proper balance. Polyunsaturated fatty acids have numerous functions in the brain, on which our nervous system, cardiovascular system, memory, learning ability, and lingual skills depend.

- that increases your risk of different diseases and premature death

Approximately one billion people worldwide lack vitamin D because they get too little sunlight, they overuse suncream, or they have chronic diseases that prevent proper utilization of the nutrient. This was shown in a new study that is published in The Journal of the American Osteopathic Association. During the summer period, health authorities and organizations issue warnings against the sun and recommend the use of suncream. These campaigns, however, should ideally be accompanied by recommendations on how to get enough vitamin D from other sources. Otherwise, the campaigns may do more harm than good, as all cells in the body need this essential nutrient, and the sun is the single best vitamin D source.
