ConsumerLab.com Tests Selenium Supplements -- Finds One with Less than 25% of Listed Amount
White Plains, New York, August 31, 2012 — ConsumerLab.com announced results today of its Product Review of Selenium Supplements. Among the supplements selected by ConsumerLab.com for testing, one was found to contain only 23.7% of its listed amount of selenium and lacked required information about the plant source of an ingredient. Six other products met ConsumerLab.com's quality criteria, having correct label information, lacking lead contamination, and, if tablets, breaking apart properly. Five additional selenium supplements tested through CL's Voluntary Certification Program also passed testing.
ConsumerLab.com tested a variety of selenium supplements, including those with selenium from yeast, selenium from kelp, selenomethionine, Se-methyl-L-selenocysteine, selenite and selenium picolinate. ConsumerLab.com found that higher cost did not mean higher quality among selenium supplements: The cost of an equivalent 200 mcg dose of selenium from the products ranged from just 4 cents to over $1.00 and the two most expensive were those which failed the review.
Selenium may provide a cancer-protective benefit, although apparently only to individuals who are selenium deficient. Selenium deficiency is uncommon in the United States due to significant amounts of selenium available from foods. Certain digestive conditions, however, such as Crohn's disease, short-bowel syndrome and ulcerative colitis, may impair selenium absorption, causing deficiency. Medications that reduce stomach acid might also reduce absorption of selenium. Studies suggest that many people in certain developed countries, including China, New Zealand, Belgium, and Scandinavian countries, do not get enough selenium in their diets. The selenium content of food varies depending on the selenium content of the soil in which it was grown.
