Product Overview

  • Foundation for Longer Life
  • 200 mcg & Vitamin E
  • Providing the Most Advanced Form of Selenium
  • Dietary Supplement
  • Yeast Free

Selenium is a trace mineral that is essential to optimal health. Few people—including physicians—realize that selenium is available in several different forms. Each form of selenium acts along a different pathway to support healthy cell division. For optimized selenium support, one should supple­ment with all three of the following forms of selenium:

  • Sodium selenite
  • L-selenomethionine
  • Selenium-methyl L-selenocysteine

Life Extension has upgraded Super Selenium Complex with a new selenium blend that combines all three of these unique forms of selenium. A small amount of vitamin E is included because it has been shown to work synergistically with selenium.

Studies suggest selenium deficiency can pose a signifi­cant health risk. For example, the body utilizes selenium to make gluta­thione peroxidase, an endogenous antioxidant enzyme almost as important as SOD (superoxide dismutase).

Selenium also supports normal thyroid and immune function in healthy individuals.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

Take one (1) capsule per day with food, or as recommended by your healthcare practitioner.

Other Ingredients

Rice flour, vegetable cellulose (capsule), l-leucine, dicalcium phosphate.

Unique and from a leader in nutrion research

Posted by NBPT100 on Oct 29, 2013

Selenium is critical trace mineral. Many people are low in in Selenium. As a result of to factory farming practices it is not as abundant in our food. This mineral is very critical for anyone who has low thyroid function (hypothyroid). It is needed for you body to produce thyroid hormone. A study has show that in some cases it was able to lower the antibodies in those with a thyroid autoimmune condition called Hashimotos disease. Leave it to Life Extension to come up with a unique product that combines 3 forms on selenium into one capsule. They have been on the leading edge of nutrition research for years and have an impressive track record of innovative researched based products. I have been using this for a few months and I trust it to be a good choice. I don't know of anything else like it on the market today. This is great protection to make sure your body is getting this important mineral. Do not supplement more than 400 mcg of selenium in a day.

Fantastic product

Posted by 5083968428010857048 on Jun 08, 2013

This is another great product from Life Extension. I have thyroid issues as a result of mercury toxicity and I find this product excellent in helping me to stabilize the Hashimotos. Since I have been using this, zinc, iodine and coconut oil, I have started to reverse the Hashimotos and I am now only borderline on the good side. I was told it was irreversible. I would highly recommend this product.

Great selenium supplement!

Posted by Rosie-Posie on Apr 12, 2013

I take this because I have Hashimoto's thyroiditis and selenium helps reduce the thyroid antibodies. This is the suggested dosage according to some doctors, and this supplement has 3 kinds of selenium so you can't go wrong with it. Also contains vitamin E which helps the absorption of selenium. You can't beat the price on iHerb!

There is no other Selenium product as good as this one!!!

Posted by Reviewer2798647 on Sep 03, 2013

If you are interested in your health, do some research on selenium. You will find that 40-60mcg of good quality Se is enough to top-out the anti-oxidant enzymes. This is where this fantastic Se complex comes in as it provides other forms of Se which are used by the body in other ways, not just the anti-oxidant enzymes (e.g. SeMC form is highly advantageous for cancer prevention/adjunct treatment). It's fairly cost effective at ~$40/year. I wouldn't use any other Se product!!!

This product was recommended on a thyroid forum

Posted by Reviewer1557740 on Nov 11, 2013

It is too early to say whether I have benefitted from this, but I think I may have done. One week ago, I had terrible pain due to having suddenly got a fallen arch on my right foot. As this complaint can be related to low thyroid function, I took this supplement. After two days of wearing shoes with supportive insoles and taking the selenium (amongst other pro-thyroid things), the foot pain had gone! The pain had been so excruciating that I actually went to the emergency department at the local hospital! I was very surprised to have NO pain at all just two days later. I am hoping the selenium contributed to this rapid recovery.
