What it is
Ceylon cinnamon is lower in coumarin, a liver-toxic compound, than the cheaper Cassia variety sold in most stores. Some trials show modest blood sugar reductions, but results are inconsistent and the actual benefit is small compared to standard treatments. Safe at recommended doses. Not effective enough to replace diabetes medication.

Time of day & tips
Take with the first bite of a meal to blunt blood sugar spikes. Always use Ceylon, not Cassia cinnamon. Avoid if you take diabetes medications without monitoring blood sugar.
