<<Disclaimer: Verify this information before applying it to your situation.>> I received a letter from Lichtwer Pharma U.S., Inc. today. They verified that their dietary supplements: Kira (St. John's Wort), Kwai (Garlic) and Ginkai (Ginkgo Biloba) are gluten-free. The Kira box is already labeled gluten free.
