Customer Ratings & Reviews

Rated 4.8 out of 5 by 37 reviewers.
Rated 5 out of 5 by Harsh smell This has a strong smell, but does not leave a bad taste or after taste. Great product overall. January 1, 2017
Rated 1 out of 5 by Did not work for me Not potent like before when it first came out. :( September 23, 2016
Rated 4 out of 5 by SeMSC Selenium Unfortunately, smell was horrible in the bottle. Maybe, product was defective or maybe selenium has bad smell. I took it with zinc and magnesium once per day. I got increase in appetite. My nails became stronger. September 7, 2016
Rated 5 out of 5 by Sounds necessary I only take this because of what I read about this necessary trace mineral. March 29, 2016
Rated 5 out of 5 by Most folks need Selenium I don't know if it's the Se or the sulfur (since we need both), but I really like this supplement. It is even more important if you also supplement with Iodine. January 24, 2016
Rated 5 out of 5 by part of my daily regiment effective part of my daily supplements regiment. December 28, 2015
Rated 5 out of 5 by Great antioxidant Very good for the immune system, cardiovascular, etc..etc...a must for the body! December 18, 2015
Rated 5 out of 5 by Good antioxidant I use this product for detoxing as well as an antioxidant. October 5, 2015
Rated 5 out of 5 by Great Price for Quality Started taking this product to help with Swansons Kelp as selenium helps with iodine uptake and processing. This is a quality product for the amount of selenium in each dose for such low cost. As a side benefit, the ridges in my nail beds seem to be flattening, and according to my wife my hair feels softer. Selenium is vital to both hair and nail health, so it's quite possible along with the Kelp that I'm getting improvement there as well. Takes about a month or two to get full benefit of both selenium and iodine build-up in the body, but well worth the wait! July 16, 2015
Rated 5 out of 5 by SELECT SELENIUM I like to take 200 mcg. of Selenium once or twice daily in support of my overall Wellness. You can read so much, from Swanson's website to all over the internet, plus in articles and books, about all we derive from Selenium. Over the decades, I always preferred to take my Selenium in the form from yeast. Still do. Swanson had this SeMSC form of Selenium on sale, and after I read their hype about it, it sounded promising, so I thought I'd give it a try. It is just fine. On par with the yeast form I have liked and used for so long. SeMSC Selenium 200 mcg. is a user friendly product as far as I'm concerned. No stinky odor, smallish-to-medium size capsule that is easy to digest with no aftertaste, economical, and effective. Works for me. November 11, 2014
Rated 5 out of 5 by Selenium SeMSC review I am very happy with this form of selenium. I chew it up with my iodine; as the iodine and selenium work together more effectively than either alone. Also, I believe this form of selenium to be more easily absorbed by the body than other forms. Swanson brand SeMSC is high quality and effective. November 28, 2013
Rated 5 out of 5 by great selenium Digests very nicely. great for my needs October 24, 2013
Rated 5 out of 5 by excellent quality Equal to the best at less than half the cost October 6, 2013
Rated 5 out of 5 by GREAT STUFF! GIVES THAT EXTRA EDGE WITH PROSTATE ECT!!! September 11, 2013
Rated 5 out of 5 by Worth it Easy to take, small capsules. I feel better and feel like I am more alert for whatever reason. Thanks Swanson, great product September 4, 2013
Rated 5 out of 5 by Thrilled to find this quality of Selenium for this great price. Helps my thyroid to work more efficiently. Thank you for selling products that I have no doubt in their authenticity. We have been using Swanson's products for years and rely on their quality, as well as knowing I am getting the best prices. July 21, 2013
Rated 5 out of 5 by My husband and I take this everyday. It helps to keep us going. I would recomend this to all. June 5, 2013
Rated 5 out of 5 by Excellent product This is a wonderful product, probably the best source of selenium there is for immune support. I am so glad Swanson carries it, and at such a good price, because it is hard to find anywhere else. I take one almost every day, and give one to my husband. I've also recommended it to a lot of people. This is, for me, a must-have product for sustained good health. January 8, 2013
Rated 5 out of 5 by Healthy and Reasonable Selenium is very important for over all good health but has been depleted from much of our farm land. Swanson makes an affordable - good quality product. I notice when I don't take it. September 19, 2012
Rated 4 out of 5 by Best Choice The SeSMC has become my standard Selenium product as it is broad spectrum and affordable, thanx to Swanson. May 27, 2012
Rated 5 out of 5 by Best form of selenium I probably get enough selenium in my diet, but I can't be sure, so this is my insurance. I only take one every three days. This form is better than selenomethione or selenium yeast (which is actually partly selenomethionine made by the yeast) because selenomethionine can be accidentally incorporated into proteins in place of methione, which isn't good. The probable reason that so many studies have failed to find benefit from supplemental selenium is because most studies have used selenomethionine instead of this form. March 30, 2012
Rated 5 out of 5 by More naturally sourced product than others This is the selenium my family and I use and it seems to work well. I love the fact it is sourced from broccoli, garlic, etc, and has higher bioavailability than other types of selenium. I also use DIM which is sourced from these types of vegetables. I try to choose products like this over others, as even minute amounts of phytonutrients are more preferable. March 22, 2012
Rated 5 out of 5 by Close to natural SeMSC is one of the most natural selenium supplements you can get right now [you can find it in garlic, broccoli or yeast]. March 17, 2012
Rated 5 out of 5 by Good deal A basic necessity, priced right, in a modest sized capsule. March 16, 2012
