Using Fucus vesiculosus for Weight Loss?

I'm reading a weight loss program that says it's natural. I'm curious and wonder what the side effects of Fucus vesiculosus.

Fucus vesiculosis is also known as Bladderwrack or kelp. It contains iodine, which may stimulate the thyroid. It may be helpful in weight loss when obesity is associated with a thyroid that is underactive due to insufficient iodine. Side effects of excess iodine are related to overstimulation of the thyroid, and include heart palpitations and symptoms of anxiety. I recommend that you consult a health care specialist before undertaking a weight loss program that uses Fucus, as it may exacerbate a thyroid disorder if taken inappropriately.
