Horse Immune Supplements
A healthy immune system is necessary for your horse to withstand stress in the environment. If your horse is a senior, working hard, travels often, or is recovering, he may benefit from the support of a supplement that promotes immune health. Immune supplements provide antioxidants such as vitamin C, vitamin E, selenium, and grape seed extract to help neutralize the damaging free radicals that are released during times of stress, illness, or heavy activity.
