I would just like to tell you of the remarkable improvement in my eight year old lab bitch who suffers from under active thyroid. She had blood tests at the vets last year on my insistence as I was sure her thyroid was under active. Her coat was thin and Brillo pad like consistency, her nails were chipping, she had a little pot belly and was generally lethargic. The tests came back and she was very underactive. The vet said the best idea would be to see how she got on and he would then consider medication. I'm not a big fan of big pharma, so I'd tried various remedies and then spotted the seaweed on your website. I put her straight on it and what a difference. Her coat is thick, no bald spots, she's beautiful and shiny, she's more energetic and back to her old self. She is on raw food too, been on it for many years, and she's stopped eating copious amounts of grass. 10*****
