Dextrose: What Is It? Is It Good or Bad?


Dextrose is a simple sugar that occurs naturally in many foods such as honey and fruit. The more complex carbohydrates in other foods must be broken down into dextrose in the body before they can be used to provide energy for optimal functioning of the human body and brain.

What Is Dextrose?

1. Properties

Dextrose and glucose are not the same. Dextrose is a monosaccharide glucose that occurs naturally in a very pure form. Because it has a very high glycemic index, dextrose can be absorbed and used very quickly by the body. For this reason, many athletes use dextrose to quickly replace the glycogen stores in the muscles which are depleted during exercise.

2. Functions in Human Body

Dextrose is vital to the human body. In addition to providing a ready source of energy, dextrose also works to increase muscle mass. When dextrose is eaten, insulin levels increase. Increased insulin increases blood flow and delivery of nutrients to cells. Cells that receive adequate nutrition tend to be healthy and function more effectively.

3. Sources

Sources of dextrose can be either natural or artificial.

4. Uses

Dextrose can be used in some food or drinks and to enhance physical performance.

Precautions for Taking Dextrose

While the right amount of dextrose is critical for a healthy body, there are also some precautions you should be aware of when using dextrose.
