Green tea extract protects collagen, an essential part of our teeth: Researchers have found that a specific component of green tea called epigallocatechin gallate (eGCG) helps to protect the surface of our teeth by inhibiting the enzymes that break down collagen. Green tea extract also has antimicrobial properties that help to reduce halitosis (bad breath). For Dr. Heff’s mints, we use a green tea extract that contains no caffeine, so that everyone is able to enjoy its benefits.
Green tea update: There have been recent news reports of rare liver injury caused by high levels of green tea extract catechins (EGCG) in some dietary supplements. Green tea has been shown to have many benefits to our health; however, if it is taken in extremely high dosages there are risks and the European Food Safety Authority (EFSA) has recommended a daily maximum dosage of 800mg EGCG. Our mints include low levels of green tea extract (5.3mg of EGCG per mint) and studies by the University of Illinois Dental School demonstrated that these levels are necessary to repair tooth decay. So we are happy to reassure all our customers that the quantity of green tea in our mints does not pose a meaningful risk to health. In fact, one would need to eat more than 150 mints per day just to reach the EFSA safety limit of 800mg per day.
