Your pony is highly mercury toxic from the ''sea'' products which have lots of mercury in them-especially chondroitins-from shark cartilage-acting like prostrate cancer in men. Lots of other little heavy metal signs as well.

Thanks. As I said in an earlier thread he is fine now. I am however keen not to put him back on the glucosamine which I took him off of some time ago....I have issues giving herbivores shellfish and I am hoping the herbal alternative will suit him. I ve always found herbal care and particularly homeopathy to be extremely effective where all the animals are concerned, however I was a bit alarmed when I opened my emails to find a statement that my pony was 'Highly Mercury Toxic!!' (Like I say he does seem fine now, thank you all for your advice.
