Do you know the secret to delaying the natural aging process? Healthy aging is not about your appearance; it’s about decreasing the risk for chronic diseases and maintaining a high quality of life. The secret to aging gracefully isn’t expensive face creams; it is in your local grocery store – in fruits, vegetables, green tea, healthy fats, selenium foods and a host of other healthful foods and anti-aging supplements that are rich in antioxidants and other potentially age-deterring compounds. It comes down to reducing a process called oxidative stress. [3] 

As we age, we become more susceptible to the long-term effects of oxidative stress at the cellular level. Oxidative stress is caused by the body producing too many unstable free radicals as a result of poor diets, exposure to toxins and smoking. Free radicals are highly unstable, lone atoms that damage cells and tissue, which can eventually lead to cell death. As these cells die off, this leads to signs of aging and chronic disease. [3]

Selenium is an essential trace mineral that is found naturally in soil, water, and some foods. Most of the selenium in the body comes from the diet. The amount of selenium in food depends on where it is grown or raised (ie: amount of selenium in soils varies a lot around the world). In the U.S., the Eastern Coastal Plain and the Pacific Northwest have the lowest selenium levels. 

The daily amount of selenium needed is defined in several different ways. For U.S.—Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person's age, sex, and physical condition (e.g., pregnancy). Whereas, Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. *DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs)*

Normal DAILY recommended intakes for selenium [2]

Birth to 3 years of age

10 to 20 micrograms (mcg)

4 to 6 years of age

20 mcg

7 to 10 years of age

30 mcg

Adolescent and adult males

40 to 70 mcg

Adolescent and adult females

45 to 55 mcg

Pregnant females

65 mcg

Breast-feeding females

75 mcg


The bottom line is that making smart lifestyle choices that are within your control are among the best things you can do to help prevent disease and slow aging, such as [3]:

  • Eat Fish - Follow the guidelines of the American Heart Association and enjoy fish at least twice a week, especially the fatty kind that is rich in omega-3 fatty acids. This is a powerful anti-inflammatory food that offers a multitude of health benefits.
  • Fruits and vegetables are powerhouses of antioxidants. Aim for a variety of colorful produce in all colors eat at least five servings a day.
  • Whole grains provide soluble fiber to help lower blood cholesterol levels and also have phytonutrient content equal to any fruit or vegetable. Strive for at least 3 daily servings.
  • Legumes are unsung heroes, packed with nutrients similar to fruits and vegetables and with very few calories. Add them to your diet 3 to 4 times a week.
  • Yogurt is rich in probiotics that help add healthy bacteria to the digestive system.
  • Nuts are a great source of B vitamins that are good for your heart and your brain. Healthy fats in nuts benefit the elastin and collagen in skin, helping to maintaining skin’s structure and keep it resilient.
  • Water is essential for hydration of the skin, muscles, circulation, and all organs in the body. Enjoy 3-4 glasses of pure water in addition to other liquids and watery foods.


Selenium is important for making many body processes work correctly including (but not limited to):

  • antioxidant support
  • Cardiovascular health, 
  • thyroid health
  • immune health
  • prostate health
  • reproduction 
  • Cognitive health
  • DNA production, 
  • protecting the body from damage caused by free radicals and from infection.


Selenium is used for: [1]  

  • diseases of the heart and blood vessels, including stroke and “hardening of the arteries” (atherosclerosis). 
  • preventing various cancers including cancer of the prostate, stomach, lung, and skin.
  • under-active thyroid, 
  • osteoarthritis, 
  • rheumatoid arthritis (RA), 
  • eye disease called macular degeneration, 
  • hay fever, infertility, 
  • cataracts, 
  • gray hair, 
  • abnormal pap smears, 
  • chronic fatigue syndrome (CFS), 
  • mood disorders, 
  • arsenic poisoning, 
  • preventing miscarriage
  • preventing serious complications and death from critical illnesses such as head injury and burns
  • preventing bird flu, treating HIV/AIDS, and reducing side effects from cancer chemotherapy.


Selenium deficiency can produce a range of symptoms. The most common ones are [4]:

  • infertility in men and women
  • muscle weakness
  • fatigue
  • mental fog
  • hair loss
  • weakened immune system

***Although selenium deficiency is rare, it’s important to make sure you’re getting enough of it and absorbing it properly.***


As with all of Dr. Kenawy's professional line products, we use the best manufactures in making our formulas. Dr. Kenawy’s Selenium formula uses patented SelenoExcell ®.  SelenoExcell is an excellent source of naturally-occurring organic L. Selenomethionine. Working as anti aging supplements, the selenium yeast in SelenoExcell has been specially formulated to be as close as possible to the form in selenium foods. It also helps reduce oxidative stress better than other forms of selenium, such as selenium methionine (SeMet). A STUDY AT PENN STATE SHOWED THAT SELENOEXCELL REDUCES OXIDATIVE STRESS BY 34%. Our bodies have a way of fighting back with the help of antioxidants. Antioxidants stabilize free radicals (oxidative stress), but they can only do so if they have the right nutrients to create the master antioxidant called glutathione. Glutathione needs an enzyme called glutathione peroxidase and this enzyme needs selenium to function properly. It’s a symbiotic relationship. Antioxidants need selenium foods or a selenium supplement to function properly. [3] † 

Bottom line: Your body needs Selenium for the production of several important body compounds, including antioxidant enzymes, or catalysts, involved in antioxidant protection and thyroid-hormone metabolism. It has been estimated that there are between 50 and 100 different selenium-containing proteins in the human body, including those that build heart muscle, red blood cells, and sperm. [3]



  • SelenoExcell® has been the subject of important clinical studies.
  • SelenoExcell® is the most clinically researched source of organic selenium in the supplement market.
  • Some studies have even been sponsored by major health agencies of the U.S government using the most rigorous clinical methods.
  • SelenoExcell organic selenium supplement originates from a non-pathogenic, non-GMO Saccharomyces cerevisiae yeast strain. It creates a yeast supplement product that is the closest to food forms of selenium, like what is found in Brazil nuts, eggs, peas, poultry, and meats. We do this because we believe it is important to consume minerals and vitamins that are as close to a natural food form as possible. However, the S. cerevisiae cells in SelenoExcell yeast supplement are dead or inactive, and only the nutritional properties remain. The cells cannot reproduce in the human body when consumed because they are no longer alive.
  • In the case of SelenoExcell, S. cerevisiae is used as a means to an end. The fermentation process for our yeast supplement replicates the natural course in which plants absorb and transform minerals from the soil into a more bioavailable form that improves the nutrition and health properties of selenium. This particular yeast is able to accumulate and incorporate selenium into the protein structure, which enhances the antioxidant properties, which fight oxidative stress in the body.
  • Organic selenium supplements from ‘high selenium yeasts’ contain as much as 1,000 to 2,000 micrograms of selenium per gram. The form of selenium in SelenoExcell is what researchers call organic, meaning it is attached to several amino acids. This factor may make it more bioavailable than others.


Benefits [3]:

  • THYROID HEALTH-Selenium and iodine have a synergistic relationship that is especially important for a healthy thyroid. Iodine is a component of thyroid hormone, and selenium as a selenoprotein helps to convert the thyroid hormone into its active form. Both minerals are needed by the thyroid in adequate amounts; too much of one can contribute to a deficiency of the other.
  • REDUCE OXIDATIVE STRESS-A STUDY AT PENN STATE SHOWED THAT SELENOEXCELL REDUCES OXIDATIVE STRESS BY 34%. Free radicals love a stressed out, poorly nourished environment and no matter how hard we try, life has a way of getting in the way of good intentions. That is why it is essential that you do everything you can to slow the development of oxidative stress. The body needs a broad spectrum of nutrients to squelch the damaging effects of free radicals. That’s why the research behind SelenoExcell is so compelling. SelenoExcell consists of three types of selenium supplements: selenomethionine, selenocysteine and methylselenocysteine, which could very likely account for its anti-carcinogenic activity and ability to reduce oxidative stress.
  • COGNITIVE HEALTH: Selenium’s antioxidant activity may help reduce the risk of cognitive, or mental, decline, as people get older.
