Rated 5 out of 5 by from Works for me. I have been taking Swanson Premium Kelp for a few years now, and it has always worked for me. It's a great product at a great price!

Rated 5 out of 5 by from Good quality - great price I get this for a family member who uses it for Thyroid support and she firmly states this product WORKS. Other places will gouge you for name brands but Swanson quality is equal to, if not better than others at a great price. SOLD!

Rated 1 out of 5 by from 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.

Rated 5 out of 5 by from using it for long time my sea vegy for the day: this is my daily dose of green from the sea.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Swanson's Kelp Kelp is the BEST natural source of Iodine. Period. Always a great price at Swanson!
Date published: 2015-08-26
Rated 4 out of 5 by from 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

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.
Date published: 2014-04-26
Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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 .

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!
