Selenium supplements for immunity

Selenium is a vital trace element that boosts our immune system and is important for the thyroid gland, muscles and nervous system. In men, selenium is also elementary for fertility. A total of 13 to 30 grammes are ideally stored in the body, especially in our muscles and thyroid gland.

From these parts of our body, selenium prevents cell damage, strengthens the function of vitamins E and C and, together with iodine, produces thyroid hormones. Thus, selenium is involved in complex processes in our bodies, which is why our body requires a sufficient amount of it.

However, our dosage of selenium is important – even when taking selenium supplements, such as selenium capsules, an excess of selenium is just as dangerous to our health as a deficiency.

How much selenium do I need per day?

The NHS recommends a selenium intake of 75 microgrammes for men and 60 microgrammes for women. If you are breastfeeding, you need 75 microgrammes daily.

Selenium accumulates in the soil, from where the trace element enters plants –the plants that we then eat – and thus the food chain. Depending on the selenium content of the land used for agriculture and the use of enriched fertiliser, the selenium content of the food on our plates varies.

Tip: You can cover your daily selenium requirement with just one Brazil nut. Lentils, tuna, coconut, meat and egg are also good sources of selenium.

What are the symptoms of selenium deficiency?

Anyone who eats a diet low in selenium or people whose selenium requirements are greater can be affected by selenium deficiency. Long-term breastfeeding women, smokers and alcoholics are considered risk groups. Gastrointestinal tract diseases and dialysis treatments can also lead to deficiency symptoms. The good news is you can test your selenium levels easily with our Selenium Blood Test.

Symptoms of selenium deficiency:

  • Fatigue
  • Immunodeficiency
  • Muscle weakness, joint weakness
  • Decrease in sperm quality

    A selenium deficiency can also have effects on a psychological level; low selenium levels mean that the risk of developing anxiety and depressive moods increases.

    You are only doing your body good with the right dose of selenium. Fatigue, garlic breath, nausea, vomiting and diarrhoea, on the other hand, indicate an overdose. Damage often affects the thyroid gland, heart muscle and liver. Conversely, long-term excess selenium increases the risk of type 2 diabetes and prostate cancer.

    Buying selenium supplements: how to optimise selenium levels

    A balanced diet contributes to good selenium levels. But selenium-rich foods are not always on our shopping lists. Selenium supplements are a simple solution to this problem. However, before you take dietary supplements, you should have a blood test or our popular Mineral Deficiency Test. This not only tests your selenium levels but also your magnesium and zinc levels.

    If you suffer from selenium deficiency, belong to a risk group or have a diet that is low in selenium, you can optimise your selenium levels specifically with the right selenium supplements. Selenium tablets with the compound selenomethionine are particularly well absorbed by the body.
