Compare every Dextrose product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Simple glucose sugar for fast energy and post-workout carbs
We rank Dextrose by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Dextrose is a simple sugar that is chemically identical to glucose, which is the main source of energy for the body's cells. It is a fast acting carbohydrate, meaning the body can break it down and use it for fuel very quickly.
It is primarily used to provide a rapid burst of energy. In a fitness context, it is often taken after a workout to replenish glycogen, which are the stored carbohydrates in your muscles that get used up during exercise.
To make this supplement, manufacturers typically start with cornstarch. This starch is treated with enzymes or acids in a process called hydrolysis, which breaks the complex starch chains down into simple dextrose sugar. The resulting liquid is then filtered and dried into a fine white powder.
This ingredient is generally mid range in price. While the raw materials are common, the cost reflects the industrial processing required to refine the starch into a pure, food grade powder.
