How We Ranked

Selenium is an essential trace mineral that is found in soil and water. It is also present in many foods, including seafood, meat, poultry, eggs, nuts, beans, and grains. Selenium is essential for healthy immune function, thyroid, and cardiovascular health. Selenium deficiency can lead to hair loss, skin problems, and even death. It is best taken in supplement form, as it is poorly absorbed when consumed in food.

We also took a closer look at the ingredients. Completely natural products, like Pure Encapsulation, were rewarded. Other products, like Dr. Mercolahave, a lot of added ingredients, like zinc, that we felt were important for overall health.

Dosages were also essential to consider. Many studies show that the average adult needs around 60-70mcg of selenite daily. However, because many people taking selenium supplements are already deficient, more is needed to help them reach optimal levels. As such, products containing the standard 200 mcg dosage, like Now Foods and Zuora, we rewarded. This helps support deficient individuals while not going too high, possibly causing an overdose.

Health Benefits of Selenium Supplements

Selenium is a trace mineral that’s an antioxidant. It helps protect cells from damage, especially from inflammation and cancer. Selenium has been shown to prevent certain autoimmune diseases such as Hashimoto’s disease and rheumatoid arthritis, improve thyroid function, and prevent cancer in some people.

Treats Inflammation

Inflammation is a crucial cause of many diseases. Some of the most common conditions that will benefit from selenium are:

  • Heart Disease (Heart Attack)
  • Cancer (Prostate Cancer)
  • Diabetes Type 2

Selenium can help reduce inflammation and oxidative stress and prevent cancer and other diseases.

Reduces Asthma Symptoms

Selenium is an antioxidant that helps to reduce inflammation. Inflammation is one of the biggest causes of asthma symptoms. Studies have indicated that selenium supplementation can reduce asthma symptoms, including flare-ups and respiratory distress.

Treats Hashimoto’s Disease

The thyroid gland is an essential part of the body’s endocrine system. This system produces hormones that regulate every cell in your body. Hashimoto’s disease causes chronic low-grade inflammation in the thyroid gland, leading to hypothyroidism and other symptoms such as fatigue, weight gain, constipation, and depression. Selenium is a powerful antioxidant that helps reduce inflammation throughout the body and the thyroid gland. Selenium deficiency is common in Hashimoto’s disease because it prevents adequate absorption of selenium through food sources like fish or Brazil nuts!

It also protects against cancer by reducing oxidative DNA damage caused by free radicals (unstable molecules that damage cells). With its ability to prevent cancer growth while maintaining healthy levels of T3 and T4 hormones produced by your thyroid gland (which helps control your metabolism), selenium supplements are a great way to prevent or manage symptoms associated with this autoimmune disorder, such as fatigue…

Improves Thyroid Function

Selenium is a trace mineral that is essential in producing thyroid hormones. If you’re deficient in selenium, your body won’t be able to produce enough thyroid hormone, which can lead to hypothyroidism. Selenium deficiency is considered one of the leading causes of hypothyroidism worldwide. Selenium supplements can help treat this condition by providing an adequate mineral supply and preventing further loss.

It also acts as a cofactor in T3 (triiodothyronine) and T4 (thyroxine) production—two hormones crucial for regulating metabolism and cell function throughout the body. Research suggests that taking selenium supplements may help reduce symptoms associated with low levels of these hormones by boosting energy levels and improving moods for those who suffer from thyroid conditions such as Hashimoto’s disease (an autoimmune disorder), Grave’s disease (another autoimmune disorder), or cancer treatments like radiation therapy or chemotherapy that affect the glandular tissue responsible for secreting these essential compounds.

May Prevent Cancer

Selenium is an antioxidant and may help prevent cancer by protecting the cells from damage.

  • Selenium protects cells from free radicals, molecules that can cause damage to a cell’s DNA. This can lead to cancer.
  • Selenium also reduces inflammation, which is linked to many types of cancer.
  • It helps prevent DNA damage in cells that could lead to cancer and reduce cell mutation rates (neoplasia).

Prevents Rheumatoid Arthritis

Selenium plays an essential role in the body. It’s an antioxidant that can help prevent and manage rheumatoid arthritis. It also helps to keep your heart healthy by lowering homocysteine levels in the blood—which is good news for those at risk of heart disease. Selenium is found naturally in certain foods like fish, meat, eggs, nuts, and seeds.

The amount of selenium you need depends on your age: adults need 55 mcg per day; pregnant women need 70 mcg per day; lactating women should consume 80 mcg per day.

Selenium is a powerful antioxidant that helps reduce inflammation and prevent cancer and other diseases

Selenium is a powerful antioxidant that helps reduce inflammation and prevent cancer and other diseases.

It is a mineral that your body needs to function properly. It’s an essential part of the antioxidant system, which helps to protect your cells from damage caused by free radicals. Selenium also plays a critical role in regulating thyroid hormone levels, affecting metabolism, digestion, and energy levels.

Some studies suggest that selenium supplementation may help slow the progression of HIV-1 infection or decrease the risk of developing conditions such as cancer or heart disease. Selenium supplements can lower blood pressure levels when combined with omega-3 fatty acids (fish oils).

Side Effects of Selenium Supplements

Selenium is a trace mineral that’s essential for good health. It helps your body fight off free radicals, which can cause damage to cells and DNA. Selenium also helps support a healthy immune system and thyroid function. When you take selenium supplements, they’re absorbed by the body and stored in tissues such as muscle, hair follicles, bones, and skin—but only if your levels are low.

If you’re taking selenium supplements consistently (or occasionally), some signs indicate you may be getting too much of this trace mineral.

Selenium is an essential mineral for health

Selenium is an essential mineral for health. It helps your immune system and protects against oxidative damage. However, too much selenium can be toxic to the body. If you’re worried about your selenium levels, talk to your doctor about taking supplements and always take them as directed.

Hypothyroidism

Hypothyroidism is when the thyroid gland does not produce enough thyroid hormone.

It can cause fatigue, weight gain, depression, and other symptoms. It may also cause muscle aches or joint pain.

Hypothyroidism can be treated with thyroid hormone replacement medication. Sometimes, it’s caused by overconsumption of selenium supplements (a mineral we get from our food).

Nausea and vomiting

Nausea and vomiting are common side effects of selenium supplementation. If you experience this symptom, it could be a sign of one of several things:

  • Overdose. You may have taken too much selenium in your supplement or overate food containing high mineral levels.
  • Toxicity. In rare cases, it can also indicate that you’re experiencing toxicity from taking too much selenium over time (this is less likely to happen if you take supplements).
  • Deficiency. A deficiency in certain minerals can cause nausea; however, if this is the case, then increasing your intake will likely help alleviate symptoms rather than making them worse.
  • Underlying medical issues such as thyroid problems or kidney disease may cause nausea and vomiting when combined with selenium supplements.

Abdominal pain (stomach ache)

Abdominal pain is a common side effect of taking selenium supplements. This usually occurs because the person has taken too much selenium or has a condition that interferes with mineral absorption. Abdominal pain and other gastrointestinal problems can also be caused by irritation of the linings of the digestive tract, which particular foods or medications may cause.

If you experience abdominal pain after taking a selenium supplement, consult your doctor to determine whether it’s related to your medication or another health issue. If you’re taking more than 400 mcg per day for more than one week, talk to your doctor about whether you should lower your dosage or stop using these supplements altogether until any issues are resolved.

Hair loss

Selenium is needed to make selenoproteins and can help prevent hair loss. Hair loss often results from a selenium deficiency, so supplementing your diet with it may help slow down or reverse this problem.

However, taking too much of this mineral can result in an overabundance of selenium in your body and cause hair loss. Many people who take supplements experience some degree of thinning or shedding after starting them, but the severity will vary from person to person based on how much they take and how long they’ve been taking it.

Notice that your scalp feels unusually oily or looks oily after starting these supplements. That might be a sign that you’re experiencing excessive levels of selenium due to overconsumption (it’s also worth noting that these are common side effects of some medications).

Nail discoloration

Nail discoloration is a common side effect of selenium supplementation and can signify more serious conditions.

  • Liver disease: Sometimes, nail discoloration is caused by liver problems. If you notice that your nails are becoming yellow or brownish and have dark spots on them, see your doctor immediately. You may need to stop taking selenium until the symptoms disappear. In rare cases, liver damage might be permanent if you don’t take care of yourself quickly enough!
  • B12 deficiency: If you’re deficient in vitamin B12, there’s a chance that this could cause mild nail discoloration as well as other symptoms like numbness/tingling in limbs (peripheral neuropathy), fatigue, and weakness due to lack of energy production through red blood cells being appropriately produced at the bone marrow level (megaloblastic anemia). In addition, to stop taking supplements with high levels like selenium chloride or sodium bisulfate (which contain bromide ions that convert into free radicals when they come into contact with moisture), consider increasing intake through foods such as milk products since they contain both folates (folic acid) along with biotin too!

Garlic breath odor

Selenium is a mineral that can cause bad breath and other symptoms. The good news is that there are ways you can prevent and treat this symptom.

  • Preventing garlic breath odor: Take selenium supplements with meals; this helps limit the absorption of selenium by your body. Also, avoid eating raw garlic since it contains more allicin than cooked or raw garlic.[1]
  • Treating garlic breath odor: If you have symptoms of bad breath, like halitosis or stinky burps, see your doctor immediately! They might be able to help fix the problem through treatment such as antibiotics or antacids.[2][3]

Joint pain

Joint pain is a common side effect of selenium supplements. It is mild or severe, depending on the amount taken and the individual’s sensitivity to selenium. If you experience joint pain after taking a dose of selenium, contact your doctor immediately. Further tests may be required to determine if there are other causes for this side effect (such as an allergy).

Joint pain can be caused by too much of a good thing: excess levels of selenium in the bloodstream can cause inflammation in some people. If you have arthritis, gout, or inflammatory bowel disease (IBD), talk to your doctor before taking any selenium supplements.

Talk to your doctor before starting any supplement regimen.

  • Talk to your doctor before starting any supplement regimen.
  • Discuss with your doctor the benefits and drawbacks of selenium supplementation, and let them know if you have any underlying health conditions that could make it unsafe for you to take selenium.

Recommended Dosage of Selenium Supplements

The recommended dietary allowance (RDA) for selenium is 55 micrograms per day for men ages 31 years or older; women age 31 years or older need about 40 micrograms per day. Pregnant women should not exceed 70 micrograms per day; nursing mothers should take no more than 85 micrograms per day because this mineral can pass through breast milk into infants’ systems if consumed by the mother during pregnancy or lactation.”

Selenium is a trace mineral found in soil, water, and some foods.

Selenium is a trace mineral found in soil, water, and some foods. It’s an essential nutrient for good health—but it’s not found in most foods, so you need to get it from your diet or from supplements. Selenium isn’t toxic in large doses, but too much selenium can cause nerve damage and even death.

If you have kidney disease or diabetes, talk with your doctor before taking selenium supplements because they may harm your health.

High dosages of selenium may cause you to experience symptoms such as fatigue and diarrhea.

High dosages of selenium may cause you to experience symptoms such as fatigue and diarrhea. The recommended daily dosage is 50-200 micrograms, with the upper limit being 400 micrograms per day. If you exceed this recommendation, discuss the risks and benefits with your doctor.

While it’s rare for people who take a supplement containing selenium in its more common forms (selenomethionine or sodium selenite) to experience toxicity from taking too much of it, it can happen if your diet is high in selenium-rich foods (such as Brazil nuts). These foods are particularly high in selenium:

  • Brazil nuts
  • Lean beef (4 oz.)
  • Sardines (1 can)

If pregnant or nursing, it’s best to err on the side of caution.

Selenium is a trace mineral found in soil, water, and some foods. It’s also an essential mineral for humans because it helps our bodies maintain healthy cells and produce DNA. Selenium is an antioxidant that protects your cells from damage caused by free radicals (harmful molecules that can damage or destroy cells). Selenium works with vitamin E to help form glutathione—a powerful antioxidant that helps protect against cancer.

It plays a role in reproduction because it activates certain enzymes in converting cholesterol into sex hormones like testosterone. Selenoproteins also help keep follicles healthy during ovulation; when there aren’t enough selenoproteins on the surface of follicles, they cannot release eggs properly. One study found that women who took 400 mcg daily of selenium had more mature oocytes than women who didn’t take supplements containing this amount (they were able to get pregnant faster after IVF treatment).

Conclusion

In conclusion, selenium is an essential mineral that can be consumed in trace amounts through food and water or can be taken as a nutritional supplement. Selenium may have some benefits for cancer prevention, but it’s important not to take too much. If you plan on taking selenium supplements, talk with your doctor first so that they can help determine the best dosage for you.
