How It Works - ASSURE® HOOF
Even when laminitis is not a concern, poor digestion steals vital nutrients from your horse. Those deficiencies can show up in poor hoof quality, lost shoes, slow growth, quarter cracks, sore feet and crumbling hoof walls.
Scientific research supports the theory that we can impact hoof health through nutrition. That’s what we do with ASSURE® HOOF.
ASSURE® HOOF promotes hoof integrity in two ways:
1) Deliver specific vitamins, minerals and other nutrients essential for
hoof health like:
• Biotin
• Pyridoxine
• Copper
• Zinc
• Lysine
• Source of methionine
• High quality protein
2) Through our exclusive GST® technology.
The ASSURE® HOOF SYSTEM
When your horse’s hooves and digestive tract need a healthy kick-start, use ASSURE® HOOF in combination with ASSURE PLUS®. The ASSURE® HOOF SYSTEM maintains healthy microorganisms that aid digestion, and supports sand and debris clearance from the horse’s GI tract.
GST® Technology
Each product in the ASSURE® line is formulated utilizing our exclusive GST® technology. ASSURE®, ASSURE PLUS®, ASSURE® GUARD, and ASSURE® HOOF, are designed to address specific concerns or individual equine dietary needs.
ASSURE® formulas contain patent-pending blends of direct-fed microbials (in other words, healthy and essential bacteria and yeasts that are commonly referred to as probiotics); calcium carbonate; whole blond psyllium husks; vitamins; minerals; and essential amino acids.
What’s more, GST® technology means using the right “delivery system” (like granules or pellets), ensuring that the beneficial nutrients your horse needs actually reach the part of the digestive tract where they will be most useful.
ASSURE® products fit readily into any feeding routine. Coupled with basic, yet important management strategies, The ASSURE SYSTEM® provides an easy and effective way to avoid digestive upsets.
