How Long Should You Feed Flower of Sulfur to Your Horse?

Flower of Sulphur, also known as sublimed sulphur, is a natural supplement that contains antibacterial, antifungal, and anti-inflammatory qualities.

It has long been used in horse care to improve hoof health, treat skin issues, and control parasites. 

But how long should you give flower of sulphur to your horse, and what should you consider before adding it to their diet? 

In this detailed guide, we’ll look at the uses of flower of sulphur, its possible advantages and risks, and the suggested duration for feeding it to your horse.

How Long Should You Feed Flower of Sulfur to Horses?

The amount of duration you should feed flower of sulfur depends on why you’re using it – 

1. Short-Term Use (1-2 Weeks)

For temporary issues in your horse, like itchy skin due to seasonal allergies or as a pest repellent, short-term supplementation for 7 to 14 days is recommended.

A typical dosage might range from 1 teaspoon to 1 tablespoon (approximately 5-15 grams) daily, mixed into feed, though this varies widely based on the horse’s size and the source of advice. (Adult Horses (1,000–1,200 lbs): 15–20 grams daily.)

2. Seasonal Use (Spring and Fall)

You might try it during bug-heavy seasons like spring or fall, giving 10-20 grams daily for a few weeks, then stopping when the issue fades.

3. Long-Term Use (Not Recommended)

You shouldn’t keep feeding flower of sulfur to your horses long-term because of toxicity risks. 

Too much inorganic sulfur over time could upset your horse’s stomach, cause colic, or even lead to sulfur poisoning in rare cases.

 

Recommended Dosage for Your Horse

There is no standard dose for sulphur flower; however, here are some recommendations:

• Horses (1,000-1,200 pounds): 15-20 grammes per day.
• Ponies: 10-15 grammes every day.

These are appropriate dosages based on historical habits rather than studies, so proceed with caution. 

Start feeding with a little amount, such as 5 grams, to see how your horse reacts, and do not exceed 20 grams without consulting a vet.

 

Potential Side Effects and Precautions

While flower of sulfur is generally safe, excessive use may lead to the following side effects in your horse:

• Digestive upset – Overuse can cause colic or diarrhoea.
• Sulfur toxicity – Rare but possible with excessive long-term intake.
• Allergic reactions – Monitor for skin irritation or respiratory issues.

Key Takeaways

You might feed flower of sulphur to your horse for 1-2 weeks to treat certain issues, such as skin irritation or pests, using a small monitored dose.

However, prolonged use might require periodic pauses. 

For your horse’s best health, provide excellent forage and consult your vet about proven and effective supplements.
