The Power of Selenium: Natural Sources and Supplements

1 comment by Stacy Facko

Selenium, a trace mineral with powerful antioxidant properties, is essential for overall health. 

Selenium is a mineral that plays a vital role in various bodily functions, including thyroid hormone metabolism, DNA synthesis and repair, and immune system function. It also acts as an antioxidant, protecting cells from damage caused by free radicals. Dr. Hulda Clark recommended taking Selenium as part of her protocol to support the body's natural detoxification processes. Her research showed that Selenium can help remove heavy metals like mercury and arsenic from the body.

Unfortunately, many people are deficient in this important mineral due to poor diet and depleted soil conditions. This deficiency has been linked to health issues such as cognitive decline, thyroid disorders, and weakened immune function. Supplementing with Selenium can help fill this gap and promote overall health.

What is Selenium and Why is it Important?

Selenium is a vital trace mineral that supports various bodily functions. As a key component of selenoproteins, selenium acts as an antioxidant, combating oxidative stress and protecting cells from damage. It also supports thyroid function, boosts immune system health, and may reduce the risk of chronic diseases. It has been studied for its cardioprotective activity, with many animal studies showing it was highly effective (1). Cardiomyocytes have their own antioxidant system in the endoplasmic retuculum, which uses slenoprotein K (2). Many of the selenoprteins have not been studied and their funciton remains unknown. 

Natural Food Sources

The highest source of selenium is Brazil nuts, which have more than a daily level in just a few. One study found that eating just 4 Brazil nuts lowered LDL bad cholesterol for up to 30 days later. Dr Gregor has a video on this study here. And Dr. Mandell made a short video recommending just 1 Brazil nut a day, to prevent getting too much selenium. Interestingly, results wer enot greater for those that ate more than 4 nuts per day, suggesting what many in natural health, like Dr. Berg, have recommended, which is to get selenium somewhere else because nuts are high in phytiic acid, which binds to minerals, including sleenium, zinc, chromium iron and magnesium.  

  1. Brazil Nuts: Brazil nuts are exceptionally high in selenium, with one nut containing around 68–91 mcg of selenium.
  2. Tuna: Seafood, particularly tuna, is one of the richest sources of selenium. It contains about 80-90 mcg of selenium per 100 grams.
  3. Organ Meats: Organ meats such as liver and kidneys are also high in selenium, providing approximately 55-67 mcg per 100 grams.
  4. Seafood: Other seafood like oysters and sardines can contain around 45-60 mcg per 100 grams.
  5. Sunflower Seeds: Sunflower seeds are another good source, offering about 79 mcg of selenium per 100 grams.

Other decent sources include eggs, with one egg containing around 15mcg or nearly 30% of your daily recommended intake. Cottage cheese is also high, containing over 30% in a cup, and 1/2 cup of mushrooms and 1 full cup of oatmeal also have around 25% (3). 

Benefits of Selenium Supplementation

  1. Antioxidant Support: Selenium's antioxidant properties help protect cells from free radicals, promoting cellular health.
  2. Thyroid Health: Selenium is essential for thyroid hormone metabolism, supporting thyroid function and metabolic health.
  3. Immune System Boost: Selenium strengthens the immune system, helping the body fight off infections and illnesses.
  4. Chronic Disease Prevention: Research indicates selenium may protect against certain cancers, cardiovascular disease, and cognitive decline.

Incorporating Dr. Clark Store's Selenium supplement into your daily routine can provide these essential health benefits, ensuring you maintain optimal well-being. Pair with zinc for powerful immune system support.

    Hi,
    I am a big fan of Dr.Clark, also a loyal customer of this store. Although I’ve just discovered Dr. Clark ‘s book not long ago, but reading the newsletter from this site already become one of my morning routine. Great info , definitely need more support from healthy living enthusiasts like me. One little issue I am going to point out is, there are some misspellings in the articles I’ve noticed recently, took me a while to figure it out, hehe.
