SeMSC Selenium 4.9 5 21 26
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
great selenium Digests very nicely. great for my needs October 24, 2013
excellent quality Equal to the best at less than half the cost October 6, 2013
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
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
My husband and I take this everyday. It helps to keep us going. I would recomend this to all. June 5, 2013
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
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
Best Choice The SeSMC has become my standard Selenium product as it is broad spectrum and affordable, thanx to Swanson. May 27, 2012
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
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
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
Good deal A basic necessity, priced right, in a modest sized capsule. March 16, 2012
Small but Mighty Love the size and Love the effect. Brazil Nuts are full of Selenium. These tiny power house pills are more convenient to take then Brazils before bed or when travelling. The "kick in" time is short and the effect long lasting. Enjoy this the affects on my sinuses. February 13, 2012
Superior form of Selenium Selenium is an important element and this is a superior form of it at the right dose. Good value too. February 1, 2010
good product if you are unable to take yeast I use SelenoExcell because I prefer yeast based Selenium and I am NOT allergic to yeast. SelenoExcell is also less expensive when it is on sale. I purchased this for my sister who cannot use yeast. Both SelenoExcell and this are biologically effective. If you are not able to use yeast, use this for your selenium. August 20, 2009
Best form Selenium After doing much research. I am going to believe this is the best form of Selenium out there. Being male I worry about heavy metals and my overall well being and this is a vital component. The price that Swanson offers it has amazing too. July 30, 2009
Ultra SeMSC Selenium A good product but to me it has an objectionable odor. I much prefer the Albion Complexed Selenium that doesn't have this odor and is more economical. December 17, 2008
BioAvailable selenium Good science for the selenium. Capsule is small enough to swallow easily. Makes me feel good to get the antioxidents in there. March 27, 2008
Overall health with Coral Calcium Even though there are 73 other minerals in Coral calcium, after taking coral calcium for 3 years, I felt that I needed extra amount of some minerals for my health such as zinc, copper, vanadium, chromium, and selenium. That's why I choose selenium from Swansonvitamins for my daily supplement. With copper and selenium I believe that I got rid of lots of bumps (fat?) and age spots as well as recovering the elasticity of my skin. I will continue to take my selenium with other supplements.
