Horseradish Nutrition Benefits and Facts

Nutritional summary

Horseradish contains high concentrations of glucosinolates (sulfur-containing compounds), particularly sinigrin, which are well-established precursors to bioactive isothiocyanates .
The sharp, piquant flavor of the root is primarily due to allyl isothiocyanate (AITC), a compound that has demonstrated antioxidant and anti-inflammatory properties in laboratory settings .
Beyond its sulfur compounds, the root provides a combination of ascorbic acid (vitamin C) and flavonoids like quercetin and kaempferol, which contribute to its overall antioxidant profile .
Early research suggests that specific compounds in horseradish, such as iberin, may act as quorum sensing inhibitors (substances that interfere with bacterial communication), though current evidence is insufficient to support therapeutic use .

Interesting fact

Despite its name, horseradish is poisonous to horses and is actually a member of the Brassicaceae family, making it a close relative of mustard and wasabi.
