Daily Maintenance

Northwest Horse Supplement is formulated by professional nutritionists to provide the correct quantities of Micro Minerals and Vitamins needed to balance the diets of Non-Gestating, Non-lactating adult and near adult Northwest Horses.

Performance Horses

Equine Athletes need as near Perfect Nutrition as possible to Rebuild and Retain Bone during demanding Muscular Activity, plus a sufficient overage to replace losses while sweating.


Stallion's nutritional needs are critically specific. For example, Selenium supports Healthy, Well-Formed, Viable sperm and Zinc contributes to Larger Testicle size for Increased Quantity of Sperm.

Halter Horses

Halter Horses must have excellent, fortified nutrition for Strong, Sound Bones and robust Healthy Appearance.


Antioxidants are important for your horse on many levels. Nature supplies antioxidants to protect us from the destructive effects of environmental free radicals. Free radicals are caused by ultra-violet rays from the sun, x-rays, exposure to pesticides, insecticides, herbicides and more.

Trace Minerals
Trace Minerals

Many horse supplements include trace minerals, really just metals with important biological functions. For horses, the most important trace minerals are: Iron, Manganese, Zinc, Copper, Cobalt, Iodine, and Selenium. Trace mineral deficiencies can cause a wide variety of health problems: including, poor hoof and hair condition, bone problems, and blood cell formation issues.

Organic Selenium
Organic Selenium

Selenium (Se) is a trace mineral, an essential nutrient that is an anti-oxidant. It protects the body from oxidative stress. A selenium deficiency may cause white muscle disease, muscular dystrophy, tying up, reproductive problems, and impaired immunity.

Selenized Yeast
Selenized Yeast

Yeast cultures and probiotics have been proven in university and field trials to improve fiber digestibility and nutrient retention when included in equine diets. Improved digestibility means the horse gets more nutrients without increasing feed costs. Fiber digestibility is also critical to maintaining normal gut function, which is of special importance in working horses fed high energy diets and during times when forage quality is poor.
