An Essential Mineral
Why do we need selenium?
You might not know it, but your body needs selenium. Like all trace minerals, it’s essential for proper body functioning, though you need less of them than you do vitamins and minerals needed in larger quantities, such as calcium and iron. That is why it is referred to as a micronutrient.
Your body uses selenium to make enzymes called selenoproteins. There are 25 of them, and some of them — such as glutathione peroxidases — work as antioxidants, which are molecules that prevent against cell damage. They protect cells by turning chemicals such as hydrogen peroxide into harmless products like water.
Lower Cancer Risk
According to some studies, selenium deficiency can lead to a higher risk of prostate cancer. Study found that people who took in higher amounts of selenium (159 micrograms (mcg) a day) had a lower risk than those with 86 mcg.
However, while supplements might lower risk of prostate cancer in people with low selenium levels, one study by the National Cancer Institute (NCI) found that for men with already high levels of selenium, supplements only increased the odds of prostate cancer.
Other studies also link selenium levels to lung cancer. In a study of over 9,000 Finnish men and women, low selenium levels were associated with an increased risk of lung cancer. The association was strongest among smokers.
Some findings suggest that selenium can help lower the risk of cardiovascular disease, but the reasons for this link remain unclear. A study of older Danish men found them to be at risk when their levels were below 79 mcg.
Selenium might also help in the treatment of HIV/AIDS. According to the Linus Pauling Institute, people suffering from the disease normally have declining levels. This is sometimes associated with increased risk of death from HIV. There is not much research on the effects of selenium supplements on people with HIV. One study found that supplements helped to greatly lower hospitalization rates among people with HIV. Another found a decrease in one biological aspect of HIV progression.
Where to Find It
Selenium is important for good cell health, with potential benefits to people with certain conditions. Selenium content in plants varies and depends on the richness of selenium in the soil. Some natural sources include Brazil nuts grown in Brazil and brown rice While selenium is a necessary mineral, high amounts are toxic. For this reason, we prefer that you NOT supplement with tablets but obtain your RDA from food sources. The Food and Nutrition Board (FNB) has set the upper limit of selenium found through food and supplements to 400 mcg a day in adults. As with any supplement, check with a healthcare provider for a level safe for you.

As well and being found naturally in the soil, there are a number of other ways to consume the mineral and enjoy the benefits of selenium. Foods naturally high in this trace mineral: See Selenium - Natural Sources
In addition to protecting against various cancers, a host of clinical studies4 show that selenium plays a role in the prevention and treatment of a remarkable array of pathologies, including:
- Cardiovascular disease
- Rheumatoid arthritis
- Alzheimer's disease
- Amyotrophic lateral sclerosis
DBM Protocol Adjunct Treatment - Selenium Supplementation Through Natural Sources
- DBM only prescribe selenium supplements on VERY rare occasions. Our selenium is sourced through food.
- According to the American Journal of Clinical Nutrition, consumption of 2 (two) Brazil nuts daily is effective for increasing selenium status.
- Be cautious of eating TOO many Brazil nuts daily, as it could most likely build up to toxic levels in body tissues
- Remember, EVERYTHING in moderation
