Miriam, I would recommend Algin or the alginate I am taking (Genestra Sodium Alginate). I've been taking it a week now, and have noticed an improvement. When I woke up today, I had no pins and needles in my hands. I couldn't believe it, especially as I'd done a lot of computer work yesterday and have a goitre on my wrist. It's rare for me to wake up without numb or tingles in one of my arms at least once in the night.
