Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Full Spectrum Bladderwrack is rated 4.4 out of 5 by 10.
Rated 3 out of 5 by from Quality control? I have ordered this about 4 times and every time it looks different (the capsules are a different color or shade). It also works differently. Sometimes great--it gives me energy. Sometimes absolutely nothing at all. I have had this issue with a couple of other Swanson products and am starting to question if there is ANY quality control here.

Rated 1 out of 5 by from Beware This product is not for everyone. If you are sensitive to iodine, beware! I thought I might need an iodine supplement since I started using Himilayan salt but after taking bladder wrack for a few weeks, I began to have issues such as extreme sleepiness during the day, terrible mouth ulcers which I could not control even with Peelu mouth rinse (which is the best product I've ever used for that problem), fatigue and finally, constant headache. I then began to consider what I was doing differently, and realized it was taking Bladder wrack. I immediately ceased taking it and within 48 hours my headaches ceased, my ulcers began to heal and after a few days I began to feel like myself again.

Rated 5 out of 5 by from Great source of Iodine I take this supplement for a natural iodine source. If you haven't already researched, you should do some searches on Dr. Brownstein, Iodine. He has his own youtube channel and goes into great detail on dosage and usage of iodine. He is has researched iodine and performed more human testing than any other doctor in the United States. He also wrote the book on why you cannot live without it. It WILL change your life if you educate yourself.

Rated 5 out of 5 by from Effective This products seems to work very well with the Thyroid Glandular (Thyroxin-Free) I take; I have been very pleased with the results

Rated 5 out of 5 by from Helpful for me. I can definitely tell the difference when I take this and when don't. It helps me with the monthly issues (cramps and such). Also, it's very affordable.

Rated 5 out of 5 by from Fucoidan on a budget I'm taking Swanson Fuicodan, and like it very much. I've rearched it on the internet, and find that Bladderwrack also has Fucoidan in it...probably at a lesser concentration. Because they are so inexpensive, I bought several of these for my friends, and they all feel very good. It is an inexpensive well being supplement that I would recommend to anyone. If you want to explore Fucoidan without spending much money, this is a good way to stick your toe in the water.
