Question: I have a horse with a torn DDFT, vet has suggested silica supplement, what do you recommend? Dr. Kellon: I have excellent results using Jiaogulan based supplements in tendon and ligament problems. Even horses with DSLD have responded. Research in humans has shown nitric oxide plays a critical role at all stages of healing. Jiaogulan is a potent stimulator of healing nitric oxide. Our LaminOx product also contains amino acids to support nitric oxide production plus antioxidants, hyaluronate and vitamin support.
