Cinnamon has long been associated with managing blood glucose—my 85-year-old mom swears by it. Advanced Strength CinSulin is cinnamon bark that has been put through a water extraction process that involves heat and pressure, concentrating its active ingredients. In addition, CinSulin is fortified with chromium picolinate and vitamin D₃, both of which have been studied for their use in managing blood sugar. Item 1351728. Warehouses/Costco.com.—Mary Arriola
