Participants will store the frozen SFR-BSE beverages in their home freezer. On the evening of day 1, participants will collect a baseline overnight void which will be returned to the study team on day 2. Each evening for 3 evenings (days 2-4; between 5pm and 8pm), participants will thaw and consume one SFR-BSE beverage. Beverages may be thawed at room temperature for 1-2 hours, or in a lukewarm (70-80°F) water bath for 20-30 minutes. Participants will record the time of consumption on the intervention diary. AE assessment and buccal cell collections will be conducted on days 3, 4, and 5 (between 8 am and 1 pm) by a study investigator or a trained research coordinator. On the evening of day 4, participants will collect an overnight void which will be returned to the study team on day 5 along with the intervention diary. Blood collection will occur again on day 5 (between 8 am and 1 pm).
