Selenium is an essential trace element that is important for our body’s proper functioning. It is a vital nutrient that can be found in small amounts in certain foods, supplements, and multivitamins.
It plays a vital role in supporting the immune system, protecting against oxidative stress, and regulating thyroid hormones.
Moreover, it may possess anti-cancer properties and reduce the risk of chronic diseases such as heart disease, Alzheimer’s disease, and diabetes.
Due to selenium’s potential health benefits, it has gained popularity among health enthusiasts and supplement consumers.
However, it is crucial to know the recommended intake and the possible risks of selenium supplementation. The intake of a high amount can lead to adverse health effects like selenosis.
Furthermore, it can interact with certain medications and supplements, leading to unintended side effects.
Therefore, it is essential to consume the recommended daily dose of selenium through natural sources like Brazil nuts, seafood, meat, and poultry.

Overview and its importance
Selenium is a trace mineral that plays a vital role in maintaining overall health and well-being.
It is an essential component of various enzymes within the body, particularly those that function as antioxidants.
The human body requires only small amounts of selenium, however, its importance cannot be understated.
It is essential for thyroid hormone production, DNA synthesis, and immune function.
It also plays a critical role in preventing cellular damage in the body by inhibiting the formation of harmful free radicals.
Deficiency in selenium can lead to a number of health problems, including Keshan disease, a condition that affects the heart and results in cardiomyopathy.
Given the importance of selenium, it is essential to ensure adequate intake of this nutrient through a healthy and balanced diet or through supplementation.
Forms of Selenium and Recommended Intake
It is an essential mineral for overall health and wellness. There are two forms of selenium that are important for human health: inorganic selenium and organic selenium compounds.
Inorganic can be found in soil, water, and some foods, while organic compounds are found in plant and animal products, such as seafood and nuts.
The recommended daily intake varies depending on age, gender, and other health factors.
Generally, adult men and women should aim for around 55mcg per day, with pregnant and breastfeeding women requiring higher amounts.
It’s important to note that excessive intake can be harmful, so it’s important to keep intake within recommended limits.
Overall, getting enough through a balanced diet or supplements can provide a range of health benefits, including improved immune function, decreased risk of certain cancers, and better heart health.
Health Benefits
Selenium is a trace element that plays an essential role in human health. It is required in small amounts for various metabolic processes in the body.
It acts as a powerful antioxidant, protecting the body from oxidative stress and inflammation. Plus, it supports the immune system and helps regulate thyroid function.
Additionally, it has been linked to reducing the risk of various chronic diseases such as cancers, heart disease, and cognitive decline.
One of the most significant benefits of selenium is its ability to prevent cellular damage by neutralising harmful free radicals, which are produced during metabolism.
Overall, consuming an adequate amount can help maintain optimal health and reduce the risk of various chronic diseases.
Sources of Selenium
Selenium is an essential trace mineral that is integral to human nutrition.
It plays a crucial role in various physiological processes, including immune function, thyroid hormone metabolism, and antioxidant defence.
While selenium deficiency is rare, obtaining adequate levels of this nutrient is crucial for maintaining optimal health.
One way to ensure adequate selenium intake is through the consumption of foods that are naturally rich in this mineral.
Some of the best dietary sources of selenium include Brazil nuts, seafood, such as tuna, shrimp, and oysters, whole grains such as wheat and oats, and animal products like chicken, beef, and eggs.
Its content in foods can vary widely depending on several factors, including soil and water conditions, farming practices, and processing methods.
Therefore, consuming a varied diet that includes a range of selenium-rich foods is essential for meeting daily recommended intake levels.
Possible Side Effects of Selenium
It is a mineral that is essential to human health, and it offers many benefits to the body.
However, improper intake of it can lead to certain side effects.
Taking high doses of selenium regularly over an extended period can cause selenosis, which includes symptoms such as diarrhoea, hair loss, skin lesions, and nervous system abnormalities.
Additionally, selenium supplements may interfere with some medications and supplements, including chemotherapy drugs, thyroid medications, and antacids containing aluminium, magnesium, or calcium.
Pregnant women are also advised to be cautious when consuming selenium supplements as high doses may adversely affect foetal development.
It is always recommended to consult a healthcare provider before taking any new supplements, especially if you have underlying health conditions or are taking other medications.
Interactions with Drugs
Selenium, a trace mineral found in soil and certain foods, has been shown to have various health benefits.
However, it’s important to note that taking selenium supplements can interact with certain medications, leading to potentially harmful effects.
These interactions may occur because they can affect how the liver and kidneys process drugs, leading to an increased risk of side effects or decreased effectiveness of the medication.
Therefore, it’s important to consult with a healthcare professional before taking selenium supplements, especially if you are taking medications such as blood thinners, cholesterol-lowering drugs, or thyroid hormones.
By discussing your supplement use with your healthcare provider, you can ensure that your intake of selenium is safe and effective for your specific health needs.
Selenium Deficiency Diseases
Selenium is a trace mineral that plays a crucial role in various physiological processes, including immune function, thyroid hormone metabolism, and antioxidant defence.
Insufficient intake may lead to a variety of health problems, particularly in regions where soil selenium levels are low.
Some studies have suggested that selenium deficiency may increase the risk of certain diseases, including Keshan disease, Kashin-Beck disease, and some types of cancer.
In this document, we will explore these and other deficiency diseases in detail and discuss the ways in which selenium intake may offer crucial health benefits.
How to Get Enough Selenium in Your Diet?
A lack of selenium can lead to a number of negative consequences, such as an increased risk of cancer, heart disease, and thyroid disorders.
Therefore, it is important to ensure that you are getting enough selenium in your diet.
There are a variety of foods that are rich in selenium, including Brazil nuts, seafood, and organic meats.
Additionally, some plant-based sources include grains and legumes, although the amount in these foods can vary significantly based on the soil they are grown in.
To ensure that you are getting enough, it is recommended that adults consume between 55 and 400 micrograms per day.
However, it is important to talk to your healthcare provider before making any significant changes to your diet or supplement regimen.
To sum up, it is an essential trace mineral that supports several vital bodily functions.
Its antioxidant properties help protect against oxidative stress, and it also plays a role in thyroid function, immune system health, and cognitive function.
While most people can obtain adequate levels of it through a varied diet, those with specific health concerns may consider taking supplements or increasing their intake of selenium-rich foods.
However, it’s crucial to talk to a healthcare professional before beginning any new supplement regimen.
Incorporating it into your daily routine could provide numerous health benefits and help you lead a healthy life.
