Dextrose
A common term for D-glucose – a simple sugar (monosaccharide) used by the human body as a primary source of fuel. Glucose is ubiquitous in nature, and is found in a wide range of carbohydrates, from table sugar (sucrose = glucose + fructose) and milk sugar (lactose = glucose + galactose), to cellulose (insoluble fiber), starch and glycogen (all of which are glucose polymers).
Dextrose is often used in pre-/post-workout supplements, energy drinks and electrolyte replacement beverages, as a source of quickly digested/absorbed energy. Dextrose may be referred to as “dextrose monohydrate” on certain supp labels.
