A 'loading dose' means feeding extra. Feel free to ask us for advice if you think your horse may benefit from a higher daily dose. A loading dose can be beneficial if your horse has recently experienced any of these: Traumatic injury to its joints. Post-operative surgery to joints, ligaments, or cartilage. There is no current use of joint health supplements and you are just beginning Equine Joint Health. Extreme lameness due to arthritis. A normal loading dose is 1 x 30g scoop, twice a day, for 14 days. Following this, drop back to the daily maintenance dose for your horse's weight.
