Fucoidan Brown Seaweed Extract 4.8 5 28 42
Seaweed Extract Most people lack the nutrients which come from the sea. I love seaweed soup and fish so also taking this supplement gives me a well rounded base of sea elements in my diet. December 17, 2013
Good product I was pleased to see Swansons offer this product that I was instructed to take. Good price too December 4, 2013
It seems to work I took it for about a month. I am not sure if it is because of this product, I seems to have more energy. I will keep taking it for a while and see. Definately do not have bad effect :-). November 29, 2013
Success! This product has been extremely helpful as a supplement to go along with vegan diet. It is the added boost I needed. September 16, 2013
Fucoidan I really feel better when running. My stride seems to be so much lighter. I'm impressed. Does not upset stomach, or interfere with sleep. August 24, 2013
I love to eat all kind of seaweed(Mozuku, Wakame, Konbu,etc.) since I was young. However, It wasn't easy to buy them as fresh in my town in New England. When I found "Fucoidan Brown Seaweed extract",I bought them right away! It's works very well on my good health. And I sent them to my two sisters live in Japan. They love it too! I'm buying your "Fucoidan" regularly last two years. Thank you for your wonderful product! August 12, 2013
Highly concentration of fucoidan highly concentration of active compound : 45% of Fucoidan per capsule with very good price February 22, 2013
great experience after 6 months I started taking this supplement with expectations of it helping in restoring my shape. I didn't try it alone but rather with more physical activities and I did loose weight like 12lbs. I haven't even started running yet and what I noticed after 6 months is the 2" hip hanging fat slowly started going away to almost none. Be it could be from increased activity but in the past the hip fat would always remain. There are other benefits like increased energy I experienced as well. This compared to Swanson best price and quality deal I have come across and is great service. I only wish they they didn't use gelatin for capsule packaging. December 9, 2012
Fucoidan-Scmoidan! Been taking this stuff for about 7 months and can't really notice a difference at all. No energy boost like some claim, and absolutely no weight loss, despite being active and lifting weights... September 1, 2012
This thing is a real energy booster!!!! also helped with my digestion July 27, 2012
Tried this and it seems to work! My husband and I are on our second bottle of this product. It does seem to work well and we have had no ill side effects. Lots cheaper than the advertized brand and works just as well and is easier to take than the liquid! We are losing weight too! June 28, 2012
Lovely stuff This is a great energizer and gives my husband and I an enhanced sense of wellbeing. June 19, 2012
It's perfect product. I'll order it continually. April 18, 2012
no noticable effect I took for two months. Did not loose any weight. Did nothing for me. April 1, 2012
good purchase i got this for my mom and so far she has liked it quite a bit. i definitely recommend to everyone who is thinking of taking it. April 1, 2012
Fucothin I am a firm believer in the benefits of products from the sea. It is nice to find a brand that is in an affordable price range - love the fact that Swanson allows you to price shop. March 26, 2012
Very effective Great natural supplement to aid in weight loss! Love this stuff, as do one of my daughters and my partner! March 14, 2012
Works better than I thought I tried this and so far I have lost 2 1/2" off my stomach, along with exercise, etc February 15, 2012
Great for energy I bought this product simply to lose weight - I haven't noticed any difference just yet after a month taking it but I do have to say my energy level is much better. January 26, 2012
Very good Product I have been using this product for 3 weeks and I've noticed I'm more alert and I have more energy. January 17, 2012
this product is the best value on the market As a retired Food Scientist I've researched this product and its competitors and found it to be by far the top brand for strength, purity and cost on the market. June 26, 2011
makes me feel like a million bucks April 21, 2011
Excellent! Excellent! I am not quite sure how you're able to offer such an effective product at this quality and cost--yet that's exactly what you've accomplished. Keep up the good work!. March 4, 2011
great price My doctor recommended a similar product, but much more expensive from another company. I am very happy with this product for the price and quality. March 2, 2011
great for memory boost Less than one week after starting this, I noticed that I was able to recall both short term and long term from my memory "bank." I was also able to memorize long sequences of numbers that I had never been capable of doing before. Great product! January 24, 2011
