Many good quality studies done in the past suggested that taking enough of this essential mineral helps to prevent prostate cancer (and perhaps others as well). It's also needed to keep the body's immune system in top shape to help it fight off infection from virus.

Those suffering from HIV/AIDS may consider taking this supplement.

Deficiency in this mineral could affect male fertility but it doesn't seem to improve sperm quality and quantity if you are no deficient in this mineral.

It seems from all the research that there are health benefits from taking this mineral only if you are low. If you have enough of this mineral in your system, taking more may not benefit you.

Bottom line, most people should probably take 200 mcg of selenium daily but no more.

Facts and Frequently Asked Questions (FAQ)

What is selenium?

Selenium is a trace mineral that the body requires for metabolism and immune system function.

How does selenium work in our body?

This mineral is involved in many essential processes in our body such as in the making of the thyroid hormone and testosterone, removing free radicals (that damages our healthy cells) and regulating sperm production.

It also acts to detoxify the body of heavy metals by binding to them. Heavy metals are known to cause cancer. Experts believe that this may be part of the reason on how this mineral might reduce the risk of cancer.

What foods are rich in selenium?

Foods that contain large amounts of selenium include Brazil nuts, fish, crab, shellfish, brewer's yeast, wheat germ, raisins, liver, and beef.

Because the amount of selenium found in food sources varies, it is much more reliable to get the amount you need in a pill form.

What about the large SELECT study on selenium and vitamin E?

The Outcome of Selenium and Vitamin E Cancer Prevention Trial (SELECT) is one of the largest human cancer prevention trial ever undertaken by any research group. It involved 35,533 men from 427 research centers around the world and it started in 2001.

Five years into the study (scheduled to be completely done in 2013), it showed that there were no benefits of reducing prostate cancer in this group of healthy volunteers by taking either selenium or vitamin E alone or in combination.

Don't write this mineral off yet for preventing prostate and other forms of cancer. There may be many reasons for this. One expert suggested that the volunteers have high selenium levels to begin with.

What about using selenium in patients with HIV/AIDS infection?

There has been research done to see how this critical mineral can slow down and even stop the spread of viral infections such as HIV in humans. In lab studies, selenium seems to stop the HIV from reproducing and infecting cells. The benefits were also seen in clinical studies and subjects infected with HIV showed that taking this supplement reduces the virus burden and improved the blood cells count. Further research is continuing in this area. Many of the researchers in the clinical studies recommend this mineral supplement for those suffering from HIV/AIDS.

We can confidently say that by not getting enough of it, your body's immune system will not be operating at maximum efficiency to fight off the virus.

Dosage & How to Take It

What dose should I take?

Research studies suggest a dose of 200 mcg daily of this mineral. This dosage, which is very safe and below the toxic dose, is more than enough to provide the benefits of prostate cancer prevention or improving sperm count and motility in infertile men.

Should I take more for added benefits?

No, you probably do not need to do that. The research studies already showed its benefits at a dose of only 200 mcg. More is not always better.
