Environmental toxic metals are quite common and thankfully, most horses seem to manage them fairly well.
That being said, the toxic metal aluminum is easily the most prevalent and damaging toxic metal affecting the horse’s metabolism. Horses don’t manage aluminum very effectively as they tend to accumulate it and have difficulty processing or removing it from the tissue.
Most aluminum comes from airborne exposures, however it can also be present in:
- Water supplies
- Medications, especially some ulcer medications
- Water and feed containers
- The air, with relatively high airborne levels of aluminum in North America
Fortunately, the fruit acid, Malic Acid, is effective in aiding the elimination of aluminum from the tissues. As a chelating agent, Malic Acid binds to aluminum and removes it from the body.
Malic Acid occurs naturally in fruits such as berries and apples; however, to get adequate amounts to detoxify aluminum, a supplement of Malic Acid is preferred.
A typical dose of Malic Acid is in the 5 to 15 gm range, which is one teaspoon to one tablespoon.
