Step 1
Give your horse adequate pasture time. Horses can meet most vitamin requirements through proper nutrition alone. Dark greens contain naturally occurring carotene, as do most hays, carrots and corn. In instances that a horse does not consume sufficient amount of carotene, you can give it an active vitamin A supplement.

Step 2
Provide enough sun. Vitamin D is a nutrient derived from the sun, so make sure that your horse has at least four hours of sunlight each day. For horses in northern climates and for those that do not meet outdoor requirements, you can supplement its diet with a vitamin D concentration.

Step 3
Make sure that your horse forages for fresh food. Moldy clover hay can cause vitamin K deficits, causing problems with blood coagulation. Additionally, horses fed poor quality hay and gray can suffer thiamine deficiencies.
