Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 4.7 out of 5 by 44 reviewers.
Rated 1 out of 5 by not a good one I need to take Kelp, but this doesn't work for me. it is nice that this one does not have the Kelp-ish taste... but it also lacks efficacy, potency, bio-availability, and worth. Icelandic Kelp (Laminaria Digitata), which is also sold here by Swanson, works right for me., despite it's Kelpiness. November 30, 2015
Rated 5 out of 5 by using it for long time my sea vegy for the day: this is my daily dose of green from the sea. October 13, 2015
Rated 5 out of 5 by Bought again! I bought this EXACT item, either singly, or as a 2 bottle deal. This was a second purchase for me. Therefore, I was, and am, very pleased, and feel that it gives me a boost, when I take it periodically. September 29, 2015
Rated 5 out of 5 by Like This product as it stands is great, I just wish for capsules. I have a problem with flat pills to get them down. I love the effect of this item but for my personal use a capsule is better for me to take. September 20, 2015
Rated 5 out of 5 by Swanson's Kelp Kelp is the BEST natural source of Iodine. Period. Always a great price at Swanson! August 26, 2015
Rated 4 out of 5 by Iodine, naturally. Iodine is considered necessary nutrient. Why not get it from a natural source? This is one of the BEST DEALS on Swansons. You get an INSANE number of days' worth of pills for the price at the suggested dosage: For about the cost of a burger and fries at a fast food restaurant, you get 500 DAYS' worth, or 1 year and 135 days. WHAT? Beat that for that price! You wouldn't have to order these again for more than a year! At the current price on Swansons, the cost of a pill-per-day comes to about 1/10th of a penny! As far as potency goes; I believe it's pretty nice for the price; or a little better than average in my opinion. The one thing I do not like is all of the calcium that is in this supplement. I already get more than I probably should without these pills. Final thoughts: If you are looking for one of the greatest deals on Swansons for an iodine supplement, look no further; you found It! :D April 17, 2015
Rated 5 out of 5 by I take this everyday Kelp helps to maintain thyroid health. It's part of my daily vitamin regimen. January 26, 2015
Rated 4 out of 5 by 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
Rated 5 out of 5 by 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
Rated 4 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by Good Product I have been feeling better and have more energy. November 16, 2013
Rated 5 out of 5 by Easy and effective way to boost iodine intake. October 30, 2013
Rated 5 out of 5 by 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
Rated 4 out of 5 Razberri ktone awesome I lose 7 lbs over 5 weeks had energy too July 13, 2013
Rated 5 out of 5 by 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
Rated 5 out of 5 by Energy Boost I can get my chores done in the morning and not have to rest in between. May 31, 2013
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 2 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by Great Product Not sure about everything it does, but I have sure been feeling better and shedding inches! March 2, 2013
Rated 5 out of 5 by 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
