Re: Garlic supplements for bug control

Hi Meghan,


I'm delighted that the Glanzen Complete is helping his skin -- that's a sign that the inside of his body is doing well, since an unhealthy skin indicates that the internal organs may be suffering nutritionally.

Yes, you can use these insect repellent preparations with Glanzen Complete. But, the active ingredient in garlic, known as allicin, is what causes Heinz Body Anemia and also is what repels insects. So, the garlic needs to be dried or heated to inactivate the allicin. That helps with the anemia risk but may not leave much insect repellent protection.

These bug repellents require more research. So, my suggestion would be to use fly predators instead and add apple cider vinegar to your horse's drinking water -- 1 cup per 10 gallons works nicely. Also give your horse some additional vitamin B1 -- Thiamin, which seems to also lessen the attraction to insects.

All the best,

Hi Dr. Getty
Nova is doing great on the Glanzen Complete...his dandruff is clearing up nicely. I had a quick question, I am pregnant during this years bug season so I don't want to spray Nova with anything for bugs not even the natural stuff that I normally use. So I was wondering what you thought about springtime bug off garlic or cheval international inside out. Both claim to not cause anemia in horses, but I was curious what you thought. We have lots of ticks in this area as well as deer flies so I want to keep him as comfortable as possible. Thank you for your time.
PS would there be any interaction between either of these and the glanzen complete?
