What is Selenium Deficiency?

Selenium deficiency is when you are not getting enough of the mineral selenium for your immune system and thyroid to function as it should. Selenium is a non-metal element in the periodic table, with a chemical formula Se. Your body needs selenium for a range of everyday uses - from protecting cells from oxidative stress to maintaining normal hair and nails. If you aren’t getting enough, through selenium supplements or your diet, you may be at risk.

Selenium deficiency affects 500 million to 1 billion people worldwide, and is caused by low nutrient levels. BetterYou can help you avoid these low levels with supplements in a spray alternative to tablets.

6 Symptoms of Selenium Deficiency

Spotting the signs of selenium deficiency is important to encouraging a healthy lifestyle. The mineral plays an important role in the body, without the right levels, your immune system, fertility, and metabolism may suffer. These unwanted side effects can be detrimental to your health, so regulating your mineral intake, and knowing what to look out for is essential to your health. Some symptoms of selenium deficiency include:

  1. Fatigue - Due to selenium’s role in turning food into energy and aiding your metabolism, selenium deficiency can cause you to feel tired and fatigued. This is also a sign of iron deficiency, and you may be recommended energy supplements.
  2. Weakened immune system - Selenium contributes to the normal function of the immune system, helping to keep you free from disease and infection. With selenium deficiency, immunity is not supported, so you are more likely to get ill due to a weakened immune system. Therefore, you may require immune system supplements to give you that added boost.
  3. Infertility in men and women - This is due to the mineral’s role in spermatogenesis. This process is the maturation of sperm cells within the reproductive organs. This mineral protects sperm from damage or mutations while they are vulnerable in their development. The mineral is also present within the tail of sperm cells. Naturally, selenium deficiency can lead to lower levels of fertility. Whilst studies are ongoing into the effect of selenium deficiency in female reproduction, it is considered to reduce fertility. Taking conception supplements can help to provide your body with the essential nutrients needed to get pregnant.
  4. Muscle weakness - An important function of the mineral is in thyroid hormone synthesis and metabolism (the process of turning food into energy). Without being able to gain energy from the food you eat, your muscles will not be supplied with enough energy to feel strong and keep you going. That’s why selenium deficiency can cause muscle weakness. There are benefits of magnesium for muscles which can help you recover after exercise and relieve tension. Weak muscles are also a sign of vitamin D deficiency.
  5. Hair loss - This vital mineral is responsible for activating an enzyme which is essential for the making of antioxidants in the body. These promote healthy hair growth, and those with selenium deficiency may experience hair loss. This can also be a symptom of vitamin C deficiency.
  6. Mental fog - Selenium is needed to make selenoproteins, which directly support cognitive function. With selenium deficiency, there is not enough selenium available to make these selenoproteins, leading to mental fog and a struggle to concentrate.

Identifying the signs of selenium deficiency could help avoid the unwanted side effects which come with it. If you think you have any of the signs and symptoms of selenium deficiency, you should see your doctor or medical professional. They may arrange for a test to determine if you are deficient and may need supplements.

How Much Selenium Per Day?

Ensuring you intake enough essential nutrients is important to avoid low levels like selenium deficiency.

The recommended daily intake of selenium is 70 μg/day for adults that are ages 18+. The safe upper limit is 300 μg/day. Do not exceed the upper limit of any vitamins or minerals unless advised by your doctor.

Are You at Risk of Selenium Deficiency?

Although selenium deficiency can affect anyone whose nutrients get too low, there are some people who may be more at risk. It’s important to understand if you may be more likely to experience the unwanted health concerns which come with low nutrient levels. Those more at risk include:

  • Those with gastro-intestinal issues - Disorders such as Crohn’s, IBS, and others which affect the gastro-intestinal tract may be more at risk of selenium deficiency. This is because the body may struggle to absorb the mineral, even if they are eating enough selenium-rich foods. BetterYou pioneered oral sprays which do not pass primary processing through the digestive system, and therefore can help people with issues such as these obtain proper nutrient levels.
  • Those with eating restrictions - Those following a restricted diet due to allergy, or lifestyle choice, may not be able to eat the foods containing enough selenium. Therefore, they are more likely to suffer from selenium deficiency. BetterYou’s food supplements are designed to provide the essential nutrients you may be missing.
  • Those who are pregnant - While carrying a child, the nutrients you intake are especially important. Whilst providing vitamins and minerals for two, it is especially important you reduce risk of selenium deficiency. Pregnancy supplements can help you keep on top of your nutritional intake, whilst breastfeeding supplements can continue to support you once your little one has arrived.
  • Those who eat food grown in soil with low selenium content - Food grown in soil that is rich in vitamins and minerals is more nutritious, because the crop intakes them from the soil. Those eating food from soil that is low in selenium, are more at risk of selenium deficiency.
  • Those with phenylketonuria (PKU) - This is because of the restricted diet of people suffering from the disorder, their ability to obtain enough selenium from their food is reduced.
  • The elderly - Due to physical, metabolic changes and the way age affects nutritional intake, those of more advanced years are more likely to suffer selenium deficiency.

If you are more at risk, or think you have the symptoms of selenium deficiency, seek medical attention. Always seek medical advice if you are worried about your nutritional levels and before taking multivitamins or supplements.
