What is selenium?

.

Selenium is a trace mineral (our body needs it in small amounts) that is a component of enzymes and proteins. We store most selenium in muscle tissue. However, the highest concentration of this mineral is in the thyroid gland. Sources of selenium are mainly fish, beef, turkey or chicken.

.
Selenium is a microelement that is extremely important for our body. Without selenium, many metabolic processes would not exist. It is the first step for antioxidant processes, i.e. neutralising free radicals.

What are the types of selenium?

.

There are two types of seleniumand: organic (selenomethionine and selenocysteine) and inorganic (selenate and selenite). Both forms are good dietary sources of selenium. Organic selenium, however, has better bioavailabilityand.

.
Selenium is an element found in soil and water. This is how it gets into food. Due to its low levels in soils and plant tissues, selenium deficiencies can often be found in the population.

Selenium - action

.

The phrase 'trace' to describe selenium should not confuse us. Despite the fact that our body does not need large deposits of this mineral, it is very important for health. How does selenium work?

Antioxidant activity

.

Antioxidants are compounds that fight free radicals. Excess free radicals lead to oxidative stressand that has been linked to a number of diseases (Alzheimer's disease, stroke or premature ageing). 

Selenium acts as an antioxidant, that is, it reduces oxidative stressand. The mineral protects the body's healthy cells from damage.

Reduces the risk of heart disease

.

Adequate levels of selenium in the body may support heart health. Research suggests, that 50% more selenium in the body results in a 24% reduction in heart disease riskand. Furthermore, other trials indicate that selenium supplementation reduces inflammatory C-reactive protein concentrationsand.

Reduces cancer risk

.

Selenium may reduce the risk of certain cancers. A review of 69 studies (on more than 360,00 people) suggested that high levels of selenium were associated with a lower risk of breast, prostate, lung, stomach or oesophageal cancerand. This effect was associated with selenium intake along with diet, not supplements.

It is worth noting that selenium supplementation may reduce the side effects of chemotherapyand. Studies indicate that taking selenium supplements improves overall quality of life and reduces symptoms of diarrhoea in women with cervical cancer.

Prevent neurodegenerative diseases

.

Selenium may reduce the risk of developing selected neurodegenerative diseases. Studies suggest that Alzheimer's patients have lower levels of selenium in their bloodand. Furthermore, other tests have shown that antioxidants (such as selenium) can positively affect memory in Alzheimer's patientsand.

.
Selenium has been shown to have positive effects on mood changes like anxiety, confusion and aggression attacks. Therefore, it may be helpful for Alzheimer's or dementia. Furthermore, selenium may slow down the development of neurodegenerative diseases.

May reduce asthma symptoms

.

Asthma has been linked to increased levels of oxidative stress in the body, which selenium can preventand. Research suggests that asthma patients with higher levels of this mineral in their bodies, have better lung functionand. Nevertheless, further tests are needed to confirm the role of selenium in the treatment of asthma.

.
Selenium is a component of iodothyronine deiodinase, showing active actions on the gland that is the thyroid gland. It is involved in the conversion of the hormones FT3 and FT4. It is a marker for diseases such as hashimoto's or hypothyroidism, as well as Graves' disease.

Product description

Vitamin D plays a crucial role in our health and well-being. It affects calcium and phosphate metabolism, which translates to healthy bones and teeth. It also helps regulate the immune system, and studies indicate its influence on the functioning of the nervous system.

Vitamin D, although called a “vitamin,” is actually a prohormone that our body produces on its own, primarily under the influence of sunlight. Unfortunately, our modern lifestyle contributes to deficiencies of this essential vitamin. Working in enclosed office buildings, using (necessary!) SPF creams, and covering the body with clothing all make it very difficult, if not impossible, to obtain adequate levels of vitamin D from sunlight. This is why appropriate, year-round supplementation is so crucial.

Vitamin D from Natu.Care is a well-tested vitamin D3 suspended in safflower oil, a plant known for its numerous health benefits. The convenient, easy-to-swallow capsule will make supplementation a part of your daily, healthy routine, improving your overall well-being.

Pros and cons

Pros:

  • Ensures proper functioning of the immune system
  • Supports the maintenance of healthy bones and teeth
  • Maintains proper heart, kidney, and muscle function
  • Tested by an independent, certified laboratory
  • Convenient and easy-to-swallow capsule
  • Clean composition - free from added sugar, gluten, GMOs, lactose, and without preservatives or colorants

Cons:

  • None.

Selenium excess

.

Selenium excess occurs in cases of chronic or acute overdose of this mineral. It is most often led to by unreasonable supplementation. 

.
We can experience selenium overdose both by overdosing on supplements and by consuming too much of this mineral with the diet. An overdose of selenium with food, however, is rare.

When to take selenium - morning or evening

.

Most experts say that selenium can be supplemented at any hour. However, some of them give examples of patients who experienced better results when taking selenium on an empty stomach. Such an action is advised against those with stomach problems. 

On the web, there is a lack of reliable research on the best time to take selenium, so ask your doctor's opinion before starting supplementation.

Can zinc and selenium be combined?

.

Zinc and selenium are essential trace elements that are key to our health. However, taking them at the same time can negatively affect the absorption of these mineralsand. These are preliminary assumptions and further research is needed to confirm this claim.

.
Many supplements on the market contain both zinc and selenium. This is unacceptable, as these elements act antagonistically and therefore cancel each other out. Therefore, if you want your supplementation to have the desired effect, do not use selenium and zinc in parallel.
.

Research suggests, that selenium deficiency during pregnancy can negatively affect the growth of the yet-to-be-born childand. Despite this, supplementation with high doses of this mineral during pregnancy is not advisable and can be hazardous to the health of the mother and foetus . It is then necessary to take 60 mcg of selenium daily with the diet.

.
Selenium is called the element of fertility. It is essential for the health of pregnancy. It also influences  spermatogenesis (the process of maturation and sperm formation)and. This micronutrient is an important factor in the treatment of infertility, aiding the process of getting pregnant on the part of both the woman and the man.

FAQ

.
. Is it worth supplementing with selenium? .

.

. Does selenium work for your hair? .

.
. Does selenium help the thyroid gland? .

Selenium is essential for the proper functioning of the thyroid gland, and selenium deficiencies can lead to the development of thyroid diseases such as Hashimoto's disease. Research suggests that selenium supplementation may benefit people with hypothyroidism, improving thyroid hormone levels and reducing inflammation.

. Can selenium be combined with magnesium? .

You can take selenium together with magnesium. The combination of these elements lowers lipid concentrations in the body and also has an antioxidant effect. As a result, they will help protect your liver from hyperlipidaemia.

See also: Liver supplements - Ranking and advice

.
. What not to combine selenium with .

Do not combine selenium with vitamin B3, or niacin and supplements containing iron, copper or zinc, as they may interfere with selenium absorption. Additionally, selenium can affect the absorption of thyroid hormones, so - without consulting your doctor - do not combine selenium with thyroid medication. Selenium may also interact with contraceptive pills, corticosteroids, statins and drugs used during chemotherapy.

. Does selenium affect weight loss? .

Selenium is not directly linked to weight loss, but it can help maintain normal levels of thyroid hormones, which control metabolism. Selenium deficiency leads to endocrine disruption, which can make it difficult to shed weight. Additionally, selenium helps protect against oxidative stress, which can cause inflammation and contribute to obesity and metabolic diseases.

. How to test your body's selenium levels .

The best way to test selenium levels in the body will be to take a diagnostic blood test. Remember - blood needs to be taken on an empty stomach. Refrain from eating for at least 13 hours before the test. Eat a light supper and turn up for the test between 7 and 10 the following day. The price of selenium testing will vary from laboratory to laboratory - be prepared to spend around £120-160.

.

Selenium quantitative testing should certainly be done by men undergoing treatment for infertility, as well as those suffering from depression, pancreatitis, asthma, cardiovascular disease and RA (rheumatoid arthritis) - all of which can lead to selenium deficiencies.
