Combine Truvia® natural sweetener, water, cinnamon and ginger in a heavy pot and bring to a simmer. Simmer for 15 minutes, until Truvia® natural sweetener is dissolved and the syrup is deeply spiced. Set aside.
Before serving, add the syrup, lemon juice and cider in a pot and keep warm over low heat (without boiling) until ready to serve. Serve with a cinnamon stick and a slice of lemon, if desired.
