In some people who take or consume molasses the molasses can make you sleep.
I sleep much better when I consume a tablespoon of molasses about an hour before bed.
The molasses contains iron along with manganese, copper, calcium and potassium all which are healthy for you and those nutrients and minerals can help your body go to sleep and stay asleep naturally.
Molasses can also help with restless leg syndrome because low iron levels are associated with being a cause of restless leg syndrome.
By increasing your intake of Iron through the molasses the restless leg syndrome may go away.
Increasing your iron content by other way such as taking Iron supplements can also help you sleep and help with the restless leg syndrome.
