Nutrition Information

Fly Formula™is an oral fly deterring supplement, designed to reduce irritation from flies. When ingested on a daily basis, the pungent aroma of the ingredients passes through the skin to discourage flies.

Garlic granules contain a Sulphur compound, which is secreted through the skin. Insects taste via their feet, and those landing on the horse dislike this Sulphur, and so are less likely to bite the horse. The added Fenugreek seeds potentiate this effect, and along with other aromatic herbs known to be disliked by insects, such as Lemon peel, Peppermint and Rosemary, help to repel unwanted attention. In addition to this, ingredients that optimise skin health, such as Chamomile, Nettle, and Linseed help to soothe any areas affected by pesky flies. The proven probiotic Yea-Sacc® ensures maximum absorption of the desired nutrients.
