Only supplement vitamin D in a controlled manner

Vitamin D is proven to be a vital nutrient for the entire organism. An optimal supply of 30-50 µg/l of vitamin D is particularly necessary for bone metabolism. If this is not ensured, bone metabolism disorders can occur. Osteoporosis, bone instability and bone fractures are the consequences. The immune system is also determined by the vitamin D content, so vitamin D is successfully used as an immunoregulatory substance in autoimmune diseases such as rheumatism or Hashimoto's thyroiditisIt promotes the TH2 cell, a subgroup of T helper cells, and has a positive effect on autoimmune intolerance. In addition, vitamin D strengthens the body's own defenses, makes it easier to fight infections and reduces the risk of developing pneumonia. It has been proven that patients with a vitamin D deficiency are 40 percent more likely to develop pneumonia than those with an adequate vitamin D supply.

Vitamin D - the dose matters

As positive as vitamin D is for the body, the danger of an oversupply is also great. Unlike other vitamins, excess vitamin D is not simply excreted. Since the vitamin stimulates calcium production in the body, uncontrolled intake, for example through a dietary supplement, can lead to hypercalcemia, an excess of calcium in the blood. This leads to various metabolic diseases with serious consequences, such as serious kidney damage up to kidney failure. Therefore, the first step should be to take a vitamin D-rich Nutrition stand and spend enough time in the fresh air. This is because vitamin D enters the body through the skin. The UV rays on the skin stimulate production and ensure that sufficient calcium and phosphate can be absorbed. In addition, edible fish with a high fat content, such as salmon, mackerel and herring, as well as milk and cereals are considered to be real sources of vitamin D. If the body gets enough of everything, the vitamin D balance should be well supplied.

Reasons for a vitamin D deficiency

But there are also patients whose supply of vitamin D is impaired. For example, as a result of chronic Gastrointestinal disease such as ulcerative colitis or celiac disease. Both can interfere with the absorption of vitamin D from the intestine. The same applies to people who have undergone surgery to reduce their weight. The skin plays an important role in vitamin D absorption. Light skin can absorb vitamin D better than dark skin. Here, the higher melanin content impairs absorption. The same applies to older skin. This is why older people in particular often suffer from vitamin D deficiency.
Nevertheless, you should choose a nutritional supplement without hesitation. In this case, it is always important to talk to the Doctor to find the right measure to bring the vitamin D balance back into balance so that serious consequences of an overdose are avoided. The Drug Commission of the German Medical Association (AkdÄ) recently warned against such an overdose. In two cases, acute kidney failure occurred with pronounced hypercalcemia, an excess of calcium in the blood, which leads to various metabolic diseases with serious consequences. The same applies to the balancing act when dealing with exposure to the sun. On the one hand, protection against skin cancer is important, on the other hand, the skin must receive a good dose of daylight every day to ensure a sufficient supply of vitamin D. Therefore, if long-term vitamin D intake is planned, the vitamin D level and the calcium content of the blood should be checked regularly. In addition, individual advice from one of our nutritionists useful to avoid dietary supplements.
