So far so ggod I have only been using this product for about a month now and so far so good. I get my physical next week with blood work so I am anxious to see how this product has helped or not. May 13, 2014
Great Product! I bought this to increase my iodine intake, and I also heard it helps get rid of water weight. I'm so glad I bought this product! I have lost around 10 lbs in the last 2 months. I take it once a day. It also helps when I feel bloated. Its awesome. April 26, 2014
So far, so good I don't really have a lot of experience with Kelp in general but this seems like a good quality product - as with all of the Swanson products I've tried. I think it's still too early to tell if it's actually doing anything, but so far, so good. I ordered two bottles and will probably reorder when I need to. December 9, 2013
Kelp I have always had trouble with brittle, breaking nails and thin hair. Thanks to Kelp, my fingernails are now strong and beautiful. My hair is getting thicker, Even my hairdresser asked me what I was doing. I love this product and would recommend it to everyone . November 24, 2013
Good Product I have been feeling better and have more energy. November 16, 2013
Easy and effective way to boost iodine intake. October 30, 2013
Great Iodine Blood Level My doctor asked me what I've been taking for iodine because my blood tests always show a great level of it in my body. She said this is unusual in her patients. I take 3 of these a day, one with each meal. October 24, 2013
Razberri ktone awesome I lose 7 lbs over 5 weeks had energy too July 13, 2013
Great Supplement I don't use much salt and this is a good substitute for iodine needed. I have used kelp for years. June 21, 2013
Energy Boost I can get my chores done in the morning and not have to rest in between. May 31, 2013
Iodine help at last I need a specific amount of iodine daily. These are high-quality vitamins however I have to take quite a few each day to reach the needed dosage which is why I put a low rating for the convenience factor. As for value, Swanson's had a terrific sale on these so I bought a year's worth at a tremendous savings. Thank you Swanson's! April 27, 2013
You need this! I read that we don't get enough iodine in our system. Our body needs it to regulate it self. The price is super cheap so why not. April 22, 2013
Out of Date I decided to try Kelp Supplements after hearing so many great benefits. To my surprise, (I received these 2 days ago) I was shocked to see that these supplements were manufactured 2 years ago!!! Most vitamins/supplements have a shelf life of 2 years. Not sure how effective this product will be since it will expire in one month. March 26, 2013
Good Spource Of Iodine Kelp is a great source of iodine. This is a great supplement and a great price to get your daily requirement! March 24, 2013
Great Product Very reasonable price, I take this product to get my iodine in a natural form. Don't want to have to get it from iodized table salt. Quick and safe form of iodine. March 24, 2013
good product I have been doing some research on this type of kelp and I wanted to be certain I would get excellent quality and purity. I feel I am getting pure products from Swanson. Purity is very important to me. I know kelp is good for you so I decided to buy this product. Good health to all! Thank you Swanson! March 12, 2013
Great Product Not sure about everything it does, but I have sure been feeling better and shedding inches! March 2, 2013
Kelp is Wonderful I used to take this product years ago. Started up again last year. Small size tablet is very easy to swallow. I believe Kelp is helping along with a super multivitamin and mineral to balance my body. I used to buy the smaller bottle; this larger one is a much better deal. I'll continue to buy this from Swanson. Great company. February 18, 2013
Good source for iodine This product is a good source for Iodine when used as a supplement. August 14, 2012
great supplement I use this in addition to some of my other thyroid regimin, it really gives a boost to my tired mornings. I am happy with the preparation of the vitamin. It is a great value. June 24, 2011
Great source of Iodine! Inexpensive, Safe and Easy way to stimulate the thyroid! May 11, 2011
Quality and price We been taking for 3 months now it is a quality product. March 21, 2011
Big Kelp Bottle Saves Space This product though similar to many other brands of kelp in potency is good as when I have a bottle of it I have a very long time before i have to reorder. Since I stockpile a bottle or a few months supply of my most used supplements, this one bottle represents most of a years supply. Shelf space is conserved. February 27, 2011
Good I like that I can get iodine from a good plant source with these... they taste pretty terrible but I can take them without too much trouble! October 8, 2009
great value Recently began using and very effective for my purposes. Effective and great value. July 23, 2009
