Garlic is a powerful little plant. It has amazing healing, disease-inhibiting, and natural fly-repelling properties that can improve your horse’s health and quality of life. In fact, garlic is considered one of the most effective natural healing elements we know of. But can a horse eat too much garlic?
It's a great question, and one that's asked often by horse owner's researching or venturing into equine garlic supplementation. In this article, we'll discuss the powerful benefits of garlic for horses and what the right amount to feed is.
Garlic is a versatile equine supplement that's been used for generations. A quick internet search will provide pages of info about its uses and benefits but may also raise questions about safety when feeding garlic to horses.
Since launching new Redmond Rock Crushed with Garlic, our loose mineral salt supplement and natural fly repellant for horses, we’ve heard your questions about how much garlic is proper to feed. You want to provide your horse with the benefits of garlic and do it safely.
So how much garlic is too much? We have some straight answers to help you feel comfortable and confident supplementing your horse with garlic.
Garlic is a potently aromatic... spice? Vegetable? Bulb? However you classify it, garlic, which comes from the onion family, packs a powerful punch. It’s been used for ages to flavor food, but also for medicinal purposes of both humans and animals—and it’s not hard to understand why.
Garlic has impressive health-promoting capabilities and helps support a strong immune system. While more research is needed, here are some of the potential benefits garlic can offer your horse:
While garlic touts a catalog of beneficial qualities, some studies like this one have shown too much of it in horses may be detrimental. Garlic contains N-propyl disulfide. It’s an element which, in high doses, can alter your horse’s red blood cells, causing Heinz body anemia. When the cells become damaged, the body removes them, and over time your horse may develop anemia.
Garlic-induced anemia can happen quickly if your horse is snacking on wild garlic or onions growing in pastures, or slowly, as a result of over-supplementing. Specifically, feeding more than 0.4 grams per kilogram body weight of freeze-dried garlic has been shown to cause Heinz body anemia in horses. That's the equivalent of feeding an 1,100-pound horse 200 or more grams per day, which is just under half a pound. That's a lot of garlic! While this amount could easily be consumed by horses eating garlic in the wild, it's unlikely you'd feed that amount on purpose.
If you suspect your horse is consuming too much garlic, these symptoms of anemia from the Merck Vet Manual may be present:
So how do you avoid garlic toxicity in a horse supplement? Correct dosing is the answer. Proper supplementation can be done safely and will ensure your horse gets all the benefits of garlic without any negative side effects.
According to the National Research Council (2009), an average 1,100-pound horse can conservatively consume 7,500 milligrams, or 7.5 grams, of garlic per day. In these amounts, studies have shown garlic supplementation is very safe and there is no danger of horses developing anemia, even if they consume garlic long term.
Crushed with Garlic is a great choice as a health booster and natural fly repellent for horses. It contains bioidentical garlic oil—the most bioactive, stable, and potent form of garlic. So how does Crushed with Garlic stack up against the NRC’s safety guidelines? The table below shows a breakdown of how much product we recommend you feed your horse daily, how much garlic is in each dose, and the garlic amounts the NRC suggests based on the indicated weights.
As you can see, Redmond Rock Crushed with Garlic contains levels of garlic that fall within the NRC’s safety guidelines. So reap the benefits!
