Sources of glucose include:
- Refined "glucose powder" is almost pure glucose and is sold as a dietary supplement. It is often available as glucose tablets, which enables "invalids" to get sugars straight into the bloodstream without any digestion.
- Most of the industrial glucose is refined corn syrup, which contains both glucose and a quite large amount of dextrin. The corn syrup is manufactured through the hydrolysis of Corn Starch to yield glucose.
- Pure glucose drinks are good sources of instant energy for sports people
