Pro Bono

Bone remodeling is a process that occurs continuously and is essential to ongoing soundness. It is the process by which damaged or old bone is replaced by new strong bone. Research shows that inadequate intake of Vitamin K is linked to low bone density and increased risk for fractures.

Pro Bono contains a bioavailable source of Vitamin K, which plays a critical role in the function of osteocalcin, known to bind minerals and protein in the bone together. Vitamin K1 is abundant in forage and leafy greens while Vitamin K2 is synthesized by bacteria in the gut. Vitamin K1 levels in fresh pasture are unstable, have low bioavailability, and are depleted quickly when grass is made into hay. In fact, research shows that horses who are removed from Vitamin K rich pastures have a reduction in bone density within 7-10 days.

Pro Bono also contains Vitamin D, which facilitates absorption of calcium and the balance of calcium and phosphorus necessary for proper bone mineralization. The calcium in Pro Bono comes from red marine algae called Lithothamnion, which helps play a role in bone formation and remodeling.

Pro Bono’s bioavailable form of Vitamin K, Vitamin D, collagen, calcium and phosphorus supports healthy bone and cartilage that is both strong and resilient, and benefits many categories of horses; young growing horses, those with limited access to fresh pasture, horses on stall rest, broodmares for fetal development, horses recovering from bone or soft tissue injury, and horses in heavy training.
