Kelp is so good for you. Rich in tons of nutrients and minerals, especially iodine, which is great for your thyroid.
I think buying real kelp from the health food store and incorporating that into your diet is much healthier than buying tablets, though I can see why supporting your thyroid could help lose weight.
Also, you should try dulse and kombu.... well, all seaweeds are great! :)
Wakame is my favorite!
I take Kelp tablets every day for my Thyroid as it is sluggish and I do notice a difference in my energy levels whist taking it. I used to eat sushi everyday and did not need to supplement, but since moving to the USA I have not had the ease of access to get sushi. Taking kelp is a worth while supplement But if you have access to fresh kelp go for it in that form.
I am not sure that Kelp can "cure" thyroid diseases. That said, I do have autoimmune thyroid problems (which is how I ended up on CC), and have re-started using iodized salt after two years I moved to the US, and sprinkle kelp granules on my meals and perhaps it is delusion but yes, I do feel more energetic since I started using it. As a matter of fact, I also chew kelp as you would do with a snack - I like it better than chips. O_o But I am also a big seafood eater, and only used iodized salt at home, and lived on the coast, so anything maritime hits home with me.
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
