How to Support Your Horse’s Immune System Naturally

Your horse’s immune system is the first line of defense against infections, allergies, and fatigue. Just like humans, horses benefit from added nutritional support—especially during times of stress, travel, weather changes, or recovery from illness.

Key Ingredients for Immune Health

• Vitamin C & E: Powerful antioxidants that support cellular repair and immunity.
• Garlic: Naturally antibacterial and anti-inflammatory.
• Omega Fatty Acids: Help reduce inflammation and support skin, coat, and immune function.
• Iron & B Vitamins: Boost energy production and red blood cell health.

Our Recommended Immune Boosters

We stock a range of trusted products from Horse First including B Well, Garlic & More, and Omega D Oil — all ideal for supporting general immune health.

When Should I Supplement for Immunity?

• During seasonal transitions (spring/autumn)
• Before and after travel or competition
• During recovery from illness or injury
• When horses are exposed to new environments or herds

What if my horse is fussy?
