Typically a dose of Blackstrap Molasses is a Tablespoon. It can be taken right off the spoon or added to any amount of water or to coffee (3/4 cup of either water or coffee is a handy ratio). My kids take it right off the spoon. They know it helps so much that they take it without being told. (They take it for leg cramps.)
I hope it is helpful to you!
