New Zealand green-lipped mussel is used as a supplement with good results for improving patients with arthritis joint swelling and joint pain. In a study of 31 dogs and another one with 45 dogs with arthritis, when giving the mussel they showed significant improvement.
In another study of 81 dogs with osteoarthritis that were fed the mussel for 50 days showed reduction of a composite arthritic score when compared to dogs fed different diets. When the NZ green-lipped mussel is included in a supplement with deer velvet antler it has a compounding effect and has shown to improve arthritic conditions and reduce joint pain.
According to Dr. P.J. Broadfoot in her book, The Efficacy of Velvet Antler in Veterinary Practice, “..velvet antler when combined with apparent synergists, such as green lipped mussel, thymus, colostrum and others, has helped animals to balance their immune system, recover from joint problems, restore normal skin function, enhance red blood cell production, and improve reproductive activity.”
