Best Selenium Supplements Identified by ConsumerLab

Best Selenium Supplements -- selenium capsules, tablets, and liquid selenium in a spoon
White Plains, New York, July 10, 2019 — Selenium is an essential mineral important for proper immune and thyroid function but taking a selenium supplement is often not necessary and, in some people, may increase the risk of cancer or diabetes. So who should avoid taking a selenium supplement, who may need one, and which selenium supplements are best? To find out, ConsumerLab recently reviewed the clinical evidence for selenium and purchased, tested, and compared popular selenium supplements sold in the U.S. and Canada, including tablets, capsules and a liquid. The findings are now available online in ConsumerLab's Selenium Supplements Review.

In its product tests and comparisons, ConsumerLab found a 200-mcg dose of selenium can cost anywhere from just 3 cents to $1.39. Although 200 mcg was the most common daily dose provided by products, be aware that it is more than most people need -- nearly four times the daily requirement for adults and far above the daily Upper Tolerable Intake Level (UL) for selenium for children. It is an appropriate dose for treating selenium deficiency. Among the products that were Approved, ConsumerLab selected a Top Pick that provides a highly absorbable form of selenium at low cost.

ConsumerLab's new Selenium Supplements Review includes test results and comparisons for 10 products that were selected for testing by ConsumerLab and for two others that underwent the same testing through CL's voluntary Quality Certification Program. Products covered in the report are: 365 [Whole Foods] Selenium 100 mcg, Allergy Research Group Selenium Solution, GNC Selenium 200 mcg, Life Extension Super Selenium Complex, Mega Food Selenium, Natural Factors Selenium 200 mcg, Nature's Way Selenium 200 mcg, NOW Selenium 200 mcg, Puritan's Pride High Potency Selenium 200 mcg, Spring Valley [Walmart] Selenium 200 mcg, Swanson Ultra SelenoExcell and The Vitamin Shoppe Selenium.

The review also summarizes the clinical evidence for and against selenium supplementation, including how it may decrease the risk of cancer in some people but increase the risk of cancer and diabetes in others. The report explains important differences among forms of selenium, such as selenium from yeast, selenomethionine, Se-methyl-L-selenocysteine, and selenite. It also shows which foods are good sources of selenium. The report discusses the causes and symptoms of selenium deficiency and how much selenium individuals need -- based on age and gender, as well as potential side effects of selenium and its interactions with drugs.
