- The FDA issued a consumer update ahead of Halloween this year, warning that eating two ounces of black licorice a day over two weeks or more could result in irregular heart rhythm or arrhythmia for consumers over 40.
- The warning notes that black licorice contains the compound glycyrrhizin, which may cause potassium levels to fall.
- Licorice root is also sold as a dietary supplement with the glycyrrhizin removed, and is referred to as deglycyrrhizinated licorice.
Confectioners shouldn't necessarily fret about this warning. Black licorice fans represent a special kind of person (and this writer in particular has a special place is his heart for black salt licorice sweets). If you're consuming more than two ounces of black licorice a day at any age, there's probably something strange going on with your lifestyle choices. But do be aware that the FDA is watching for overdose cases.
