Yes, horses can eat blueberries! These antioxidant-rich berries are safe for horses and make a nutritious occasional treat. Most horses enjoy the sweet-tart flavor, and blueberries offer genuine health benefits in small amounts.

Are Blueberries Safe for Horses?

Blueberries are completely safe for horses. They contain no toxic compounds and are easily digestible.

What makes blueberries safe:

• No toxic compounds
• Small size reduces choking risk
• Soft texture, easy to chew
• Natural, whole food

Nutritional Benefits

Blueberries are often called a “superfood” for good reason:

Antioxidant Powerhouse

Blueberries contain some of the highest antioxidant levels of any common fruit:

• Anthocyanins: Give blueberries their color; powerful antioxidants
• Vitamin C: Supports immune function
• Vitamin E: Supports muscle health

Other Nutrients

• Fiber: Supports digestive health
• Vitamin K: Supports blood health
• Manganese: Important for metabolism

How Many Blueberries Can Horses Eat?

Blueberries contain moderate sugar, so portion control matters:

• Occasional treat: 1/4 to 1/2 cup
• Regular treating: Small handful (10-20 berries) a few times weekly
• Maximum per day: About 1 cup for average-sized horse

Why moderation matters:

• Sugar content adds up
• Can cause loose manure if overfed
• Should complement, not replace, regular diet

Fresh vs. Frozen Blueberries

Both are safe for horses:

Fresh: Best flavor and texture; horses typically prefer these

Frozen: Safe and convenient; a cooling summer treat. Let thaw slightly for easier chewing, or serve frozen for extended enrichment.

Dried: Safe but more concentrated sugar. Feed smaller amounts than fresh.

Blueberries for Metabolic Horses

While blueberries have health benefits, they contain moderate sugar:

• Horses with EMS, IR, or Cushing’s should have limited amounts
• A few berries may be acceptable—consult your vet
• Consider lower-sugar alternatives like cucumber or celery for regular treating
