Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from Best Choice The SeSMC has become my standard Selenium product as it is broad spectrum and affordable, thanx to Swanson.

Rated 5 out of 5 by from Selenium Works well fo rme.
Date published: 2012-05-11
Rated 5 out of 5 by from 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.
