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.

Iron is one of most important trace elements because of its role in the hemoglobin of the red blood cells that deliver oxygen to all cells and tissues in the body. Around two thirds of the body's total iron supply is found in the red blood cells and in muscle tissue. Around a third of our iron is stored in the liver, spleen, and bone marrow where the red blood cells are produced. A very small amount is used in vital enzymes in the brain, among other places. The organism has a limited ability to excrete iron through the intestinal system, the bile, the urine, and the skin. Moreover, iron is excreted through menstrual blood and breastmilk. An adult contains around 3-6 grams of iron. One litre of blood contains around 500 mg of iron. It is iron that gives blood its red colour, and the oxygenated blood in our arteries is lighter than the deoxygenated blood in our veins.

Nowadays, fruit, potatoes, and vegetables in general contain very little vitamin C, and the majority of people fail to eat the recommended amount of these foods, in the first place. Unhealthy diets and lack of vitamin C increase the risk of colds, influenza, and other infections, simply because the immune system consumes large amounts of vitamin C in connection with the first explosive attacks that prevent virus from causing an infection. Vitamin C also has an important role in battling infections and preventing them from dragging on and leading to complications such as bronchitis or pneumonia.

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.

During the winter period, many of us have runny noses and some may end up in bed with a bout of flu. Now is the time to prime your immune system by getting all those vitamins and minerals that your diet is not always able to provide you. That way you can ward off germs and avoid unnecessary sick days. But what effect does vitamin C, vitamin D, selenium, and zinc have on the immune system’s different “troops”, and how much do we need?

It is hardly a coincidence that so many of us contract virus infections in the course of the winter. It is because we lack vitamin D, which we are unable to synthesize when the sun sits too low in the sky. Danish scientists have discovered how vitamin D activates the immune system, and a comprehensive meta-analysis shows how vitamin D supplements can prevent colds, flus, and related complications.

Zinc strengthens the immune defense and controls inflammatory conditions such as eczema. According to a Finnish meta-analysis, high-dosed zinc supplements can help the immune defense fight a regular cold much faster. It turns out that there are widespread zinc deficiencies. First of all, sugar, birth control pills, inorganic iron supplements, and normal ageing processes impair the body’s zinc uptake. Secondly, it may be difficult to get enough zinc if you are on a vegetarian or vegan diet. Not only does a zinc deficiency have a negative effect on your immune defense and skin health, it also upsets the countless enzymatic processes in which zinc is involved.
