Selenium…a Cancer Promoter?

Question: from Dennis

My wife has some Xtend-Life Total Balance Women's Premium supplements. Recently she read that selenium, rather than helping to prevent cancer, actually promotes cancer. Since she has a history of melanoma, she has stopped taking the supplements. Do you have any plans to remove selenium from your TB Women's Premium supplements?


Answer: from Warren

Hi Dennis,

I would really like to know where your wife read that selenium promotes cancer. Selenium is a really essential nutrient with proven efficacy in helping reduce the risk of cancer. In fact it is an essential nutrient and the lack of it may well promote cancer.

If you could give me the source of this information I would be happy to get back to you with more information. There is a lot of misinformation circulating about various nutrients and I suspect this is in this category. None of our researchers, formulators and Doctors are aware of this and we are constantly keeping up to date with latest news and we are unaware of this.

If there was even the slightest doubt or evidence to support that selenium was likely to promote cancer I can assure you we would not be using it. Selenium deficiency in the soil is believed by scientists to be a significant factor in the poor health of many people.

Hi Warren

Just curious with your age. In this post, you are 63, in your reply a day earlier to David for "what about this for a supplement regime", you are 61.

You sound meticulous! For me, age doesn’t matter as long as you’re healthy. Right?

Hi Scott

The blog entry titled "What about this for a supplement regime" is nearly two years old. It was previously raised on Warren’s Blog in September 2008 and we felt it was necessary to include it on the Xtend-Life Blog for new visitors.

At the top of the entry, there is an explanation of this in bold. Feel free to click on the link and read through the various topics, questions, and other entries posted on Warren’s Blog.

Sorry for the misunderstanding – hope this helps clear any confusion.

Hi Warren,

Since 2010, when this was written, the SELECT study has in its results of 2011 and especially 2014 practically confirmed the fear that excessive Selenium can PROMOTE prostate cancer. I am concerned about this since I regularly take Total Balance Premium for Men and Cardio Support each of which include higher-than-RDA doses of selenium, let alone together. The SELECT panel recommends that men of age over 55 do not go over the RDA for selenium or increase their risk of devastating prostate cancer. Could you please update your feedback on this, and if necessary the selenium dosage in your products?
