Buying Guide
Choosing supplements for an older horse involves balancing goals, safety, and palatability. Consider these factors to tailor a plan that aligns with your horse’s needs and your management style.
- Define goals: Prioritize weight maintenance, joint health, hoof integrity, or calmness. Older horses often need a combination approach, so select products that complement one another without duplicating ingredients.
- Key ingredients to look for:
– Weight management and muscle support: high-quality protein sources and essential amino acids.
– Joint health: glucosamine, chondroitin, MSM, hyaluronic acid, and green-lipped mussel.
– Hoof health: biotin, methionine, and zinc.
– Calming support: tryptophan, magnesium, and certain B vitamins, with a non-sedative profile for show readiness. - Form and palatability: Pellets, crumbles, and powders vary in acceptance. For seniors with reduced appetite, choose palatable textures or flavors and gradual introduction strategies.
- Feeding plan and dosing: Follow label directions and adjust gradually if adding a new supplement. Consult a veterinarian for dose adjustments based on weight, activity, and health status.
- Safety and show rules: If competition is a goal, verify that the supplement is labeled show-safe and free from prohibited substances. Avoid products with unnecessary fillers or artificial additives.
