Elite Science VET is a nutritional supplement for dogs and cats that supports gums, gingiva, and joints. 1-TDC® contains a unique blend of 1-tetradecanol complex, a beneficial ingredient. This helps to maintain and support healthy gum and gingival function. 120 tablets, unopened. It works wonders for my cat with stomatitis, but I bought too many with the help of a friend overseas. I'm selling them to cats and dogs in need.
