Health benefits of Selenium

Selenium is a micronutrient in the body that serves several functions. This mineral that must be obtained from dietary sources is key to certain body systems including cardiac muscles, joints, immune system and the reproductive system.

Its amount in the body also greatly depends on the source of nutrition. If the crops are grown in selenium-poor soils, then developing a deficiency in the course of time is almost inevitable. Populations of certain regions of Europe and Asia are, particularly at higher risk.

Vitaminfood ships to all regions and is a great asset for these populations and can be used to solve more than just this nutrition problem. Use the asset and live a healthier life starting now…all you got to do is decide.

Health benefits of selenium in the body.

1.       Production of proteins

Selenium is integrated into the structure of a certain class of proteins as an amino acid. Without selenium, this class of proteins ceases to exist. These proteins are called selenoproteins. Scientists have discovered more than 25 selenoproteins.

Selenoproteins are involved in embryo development, antioxidant defenses, muscle function, sperm production, thyroid hormone metabolism and immune system’s response to vaccination. These are all vital stages and systems of our lives that critically depend on selenium for its efficiency.

P. S selenium might help your body in adapting to the vaccine and building immunity so that we can all soon go out to the parks and parties. That is what it does.

2.               Antioxidant functions

Selenoproteins have also often been referred to as antioxidant enzymes. This is because they prevent cellular damage, especially in thyroid gland cells. Selenoproteins catalyze reactions that oxidize the free radicals produced in these cells as well as in the other organs they are located in.

In the heart, selenium helps reduce the risk of developing heart disease from oxidative stress.  Elsewhere selenium reduces the risk of developing cancer as it is also greatly linked to free radicals. It helps maintain good vision as well.

3.       Thyroid gland functioning

The thyroid is greatly regulated by two elements, iodine and selenium. These two have a synergistic relationship that affects the functioning of the thyroid gland and the production of thyroid hormones. These hormones control sleep, appetite, temperature, weight and energy production.

The thyroid is central to the metabolism in organs and muscles. The highest concentration of selenium is also within the thyroid showing its great focus on the regulation of thyroid functions.

4.       Slows down aging

Ensuring you get enough selenium can help slow down aging and inhibit the expression of signs of aging. Its content in the body declines with age because the efficiency of absorbing and holding onto it also reduces. However, actively maintaining healthy maintain will ensure that its processes are not affected.

It will therefore serve as an antioxidant and prevent the damage done to cells in the eyes for vision and brain. Good vision and slow cognitive decline will be the effects. Selenium is but one among the several vital and essential nutrients whose levels are key in slowing down the process of aging. Vitaminfood contains all these nutrients to help replenish your stores as age sets in.

5.       Cancers

Selenium helps reduce the risk of several cancers. This is obtained from the possible correlation of low-selenium levels in patients and a noted decline in the risk after supplementation.

It also helps in managing the rate of progression. More than 100 small animals have shown less new tumor development after boosting the selenium content in their bodies. This provides a great chance of having an almost undisrupted life and increases the chances of survival.

These cancers are of the breast, prostate, lung, colon, rectum, pancreas, ovary and cervix.

Selenium supplementation in patients is a viable option if advised by a medical doctor. A normal recommended dietary amount deals with regulating cancerous cells from developing into cancer.

6.       Suppresses viral burden

This means that selenium helps reduce the number of viruses circulating in the blood during virus infection. For infections like HIV, 200 micrograms supplementation has been shown to slow down the rate of progression.

Destroying the number of viruses within the bloodstream limits their spread to other organs and their ability to reproduce and colonize different tissues. This could as well help in keeping the disease localized to its point of origin and make it easy.

7.       Counteract effect of heavy metals

This one of the more important uses of selenium medically. It is administered to counteract the poisoning effect of heavy metals like lead which are toxic to the cells and slows down the body’s processes.

8.       Selenium has been linked to other benefits including:

-          Helps with asthma-like symptoms

-          Managing rheumatoid arthritis

-          Managing cardiovascular disease

-          Improving malabsorption in children

-          Reduce DNA damage by solving oxidative stress

-          Boosts immune system in case of respiratory tract infections




Selenium content in food depends solely on its amount in the soil. Unlike most other minerals needed by the body, the amount of selenium is often quite low for the plant to take up and accumulate excess. This results in deficiencies in a large percentage of the population in that areas. This includes China, HIV people, South Western USA, parts of Russia and the majority of Europe.

Processed and highly refined foods are also highly likely to have inadequate selenium contents. All in all, most people are likely to have a selenium deficiency or barely have enough of it.

The symptoms include:

·         Hair loss

·         Nausea

·         Vomiting

·         Headaches

·         Confusion

·         Lethargy

·         Seizures

·         Mood swings

Long-term effects

Selenium deficiency has long-term effects as well. The two common ones are:  Keshan’s disease which is a form of cardiomyopathy meaning that the heart muscles get affected and could result in weaker contractions or irregular heartbeat. The second one is Kashin-Reck’s disease which is a form of osteoporosis.

These two can be prevented by maintaining healthy selenium content by either dietary intake or regular supplementation in selenium-poor locations.


Toxicity- selenium is toxic if consumed in large doses. The symptoms include: hair loss, dizziness, headaches, nausea, headaches, skin flushing, vomiting, nail brittleness, lethargy, skin rash and lesions, tremors and seizures, irritability, muscle soreness. Caution should be taken especially when supplementing.

 Vitaminfood and selenium

When it was first discovered, selenium was thought to be a toxin but later established as an essential mineral. More discoveries have proven its importance in the body and so should it be treated as such. Vitaminfood delivers selenium in the best package ever, alongside all the other 27 essential vitamins and minerals. Get your complete nutrition package today.
