Many products for animals are used by humans and vice versa. I've been using DMSO for decades and it's said for animals only. It's for company's protection, I guess...but I have been working with all supplements for going on 30 yrs. Thanks again for the Absorbine tip,.

My neighbor's cat got another year of life from it's cancer, thanks to her giving him Grape Seed Extract. And there are vets that have a line of Grape Seed Ex for animals....how different it is from humans, don't know, if any. It's all bottom line $$$ in the end.
