Vitamins dietary supplements are very popular. But more and more is the realization that healthy people who have a right diet actually have everything they need. But there are exceptions.
Consumers spend billions of dollars on dietary supplements every year. Most of the preparations are useless, at least for people with a regular diet. In the worst case, the often overdosed supplements and juices can even be harmful. For certain groups and in exceptional situations, however, the supplementation of vitamins can be useful. We will explain to you in which cases the most popular dietary supplements make sense.
The sun vitamin D is currently much discussed. It is so called because the body produces most of the vitamin with the help of sunlight. Small amounts can also be ingested through food, especially oily fish, egg yolks and liver. It has been proven that vitamin D keeps the bones stable and helps to preserve teeth. The vitamin is therefore also suitable for the prevention and treatment of bone density.
It is well known that calcium is important for bones and teeth. The supplement is also needed for the function of muscles and nerves and for blood circulation. Since calcium is found in many foods, especially dairy ones, you can confidently do without supplementation. As a rule, you will live more healthy with it: because many calcium supplements are dosed far too high. Overdosing due to a very high calcium intake can lead to kidney stones in the long term for example.
Magnesium is one of the top sellers among dietary supplements. The supplement is involved in the metabolism, muscle and nerves. If the body lacks it, it can lead to cramps and states of fatigue. With lots of vegetables and whole grains, you don’t need magnesium supplements badly necessary. Magnesium deficiency can occur particularly in old age and whenever a lot of fluid is lost, for example through drainage. In this case, supplementation can be useful. Food supplements containing magnesium are often too high in doses, which can lead to a drop in blood pressure in particular. Always ask a doctor for advice. An additional magnesium intake of 200 mg per day is recommended. An overdose with food is not possible, but it is possible with high dose food supplements.
It would be too nice to get through the year without a cold. However, it has not been established whether zinc supplements can help you, as is often promised. That we are dependent on zinc is undisputed. The trace mineral is involved in all life phases and plays an important role. Since zinc is found in many foods and we only need small amounts, zinc deficiency is rather rare. Rather, there is a risk that we will exceed the recommended daily amount. And that is not without danger: zinc is a heavy supplement and if overdosed, it can lead to poisoning and change the white and red blood cells.
