Selenium is an essential mineral, meaning that you can only get it through the food you eat in your diet or via supplementation.
This mineral offers numerous health benefits, such as an improved immune system and heart health. Generally, plant based diets provide very little selenium, so it is worth making sure you are not deficient. Good dietary sources of this mineral include milk and yoghurt, which for obvious reasons cannot be consumed.
Taking supplements that contain selenium may help if you are not getting enough through diet alone.

- Prevents mental decline. Oxidative stress is believed to be involved in both the onset and progression of neurological diseases such as Parkinson’s, multiple sclerosis, and Alzheimer’s . Selenium has been shown to reduce oxidative stress. Research has also found that those who undertake the Mediterranean diet, a diet that involves eating foods rich in selenium like seafood and nuts, had a lower risk of developing Alzheimer’s .

Possible Side Effects Of Taking Selenium?
Research has found that long term use of selenium, or too much selenium, could result in potentially dangerous side effects being experienced, these include:
- Nausea or vomiting
- A lack of energy, feeling irritable or very tired
- Hair loss, mild rash, brittle fingernails, and white streaks on your nails
- Tremors and feeling light-headed
- Muscle tenderness
- Flushed skin
- A metallic taste, bad breath, and strong body odor
- Easily bruised and bleeding
If you experience any of these side effects then I would speak to your doctor.
I would recommend emergency medical help if you encounter the following signs of an allergic reaction: hives, difficulty breathing or swelling of your face, lips, tongue, or throat.
Precautions Of Selenium
Research indicates that if you are pregnant or breastfeeding then it is recommended you avoid selenium doses of over 400 mcg daily.
A little bit can be very good, but once you go above a certain level there can be side effects.
- Dr. Eliseo Guallar of Johns Hopkins University in Baltimore
Others who should avoid supplementing with selenium include:
- Those undergoing dialysis
- If you have an underactive thyroid
- If you have had skin cancer in the past
- Are going to be having surgery in the next 2 weeks
What Are The Different Types of Selenium Supplement?
There are 4 different types of selenium supplement:
- Selenium sulfide - A topical substance usually used to relieve itching and flaking of the scalp.
- Sodium selenite - An inorganic compound is mainly used in the manufacture of colorless glass. It is also used in pet food.
- Selenium-enriched yeast - This is an organic form produced from yeast fermentation. The yeast is often used in both animal and human food production.
- Selenomethionine and Selenocysteine - These are naturally occurring amino acids that are found in foods such as Brazil nuts, cereal grains, soybeans, and grassland legumes.
Of these 4, the bottom two types of selenium are the ones I would recommend. This is because they are organic and are not removed as easily by your kidneys, so offer more health benefits.
Why Do We Need Selenium Supplementation?
The food you eat will have an impact on your selenium intake. The problem is that the concentration of this mineral will be different in the soils around the world, meaning that the content within foods will differ too.
Research has found that there are other factors that may cause a selenium deficiency, such as dialysis, HIV infection, smoking, and heavy alcohol consumption.
If you believe that you have a deficiency of selenium then it may be an idea to speak to a doctor who will be able to perform a test by analyzing your blood, urine, hair, and nails.
Some people are advised to take supplements under medical guidance and should talk to their doctor if they are worried.

How To Choose The Best Selenium Supplement
When choosing the best selenium supplements you will need to pay close attention to the type of selenium it contains.
The different forms of selenium are absorbed and metabolized differently. It is recommended that you opt for an organic variety rather than inorganic selenium.
Inorganic selenium will be quickly absorbed in your intestine, but will not be retained. It will be filtered out by your kidneys and excreted as urine, so the health benefits are lost.
Another factor to take into consideration when choosing supplements is its dosage.
Most adults need around 55 mcg of selenium daily, but those who are deficient will need more. Therefore opt for a supplement that contains 200 mcg of this mineral.
What Are The Symptoms Of Selenium Deficiency?
The symptoms of selenium deficiency are infertility in men and women, muscle weakness, fatigue, mental fog, hair loss, and a weakened immune system.
What Is The Recommended Intake Of Selenium?
The recommended intake of selenium is 55 micrograms (mcg) per day for adults. Pregnant women should be consuming 60 mcg daily while lactating women should consume 70 mcg a day.
Is It Safe To Take Selenium Every Day?
It is safe to take selenium products every day, but only for the short term, and then only in doses less than 400 mcg.
It is not recommended to take more than this dosage, nor is it recommended to take it long term. Doing so may result in selenium toxicity developing.
