Grazaid is a palatable blend of broad-spectrum toxin binders, salt, magnesium, live yeast probiotics and yeast derivatives as a nutritional digestive aid and to supplement mineral levels where dietary intakes may be inadequate. Mycotoxins in the hard feed are often undetectable to the human eye and nose but may be present at low levels in grains and grain-based feeds, causing under-performance in horses. Mineral imbalance in pasture can cause dietary problems for horses, especially during spring and autumn when lush pastures can be high in potassium and nitrates.
