Turmeric, devil's claw, green lipped mussel, coconut oil. Bromelain too but it has to be given at least an hour before food to get the anti inflammatory effect, otherwise it just digests any protein in the food. It can boost the effects of turmeric though.
Give mine Dorwest Glucosamine & Chondroitin, my 9.5 year, old has been on it for around a year & the 12 & 16.5 year old for around 2 years....maybe longer as I xant remember when I started them on it.
