Trehalose

Trehalose is a carbohydrate built from two glucose units linked by an alpha,alpha-1,1 glycosidic bond. This disaccharide occurs in mushrooms, algae, insects and some seeds. It is less sweet than sucrose and remains stable in heat and acid, allowing plants and animals to use it as a protective molecule during dehydration and stress.

Explanation

Trehalose’s structure gives it distinctive properties that make it useful beyond being a simple sugar. It is digested more slowly than sucrose or maltose because the bond between its glucose units resists breakdown in the intestine. This slower digestion leads to a gradual release of glucose into the bloodstream, which can help maintain blood sugar without the sharp peaks and crashes associated with more rapidly absorbed sugars. In some endurance formulas, trehalose is combined with faster acting carbohydrates such as glucose or maltodextrin to provide both immediate and sustained energy. Because it is less sweet than table sugar, manufacturers can include larger amounts without making a drink overly sweet or heavy.

Trehalose also has stabilizing properties. It helps prevent proteins and cell membranes from unfolding, so it is used in food preservation, pharmaceuticals and cosmetics to protect sensitive ingredients. In powdered sports drink mixes, trehalose can improve shelf stability by minimizing moisture uptake and maintaining texture. Its ability to hold water and protect cells is what allows certain organisms to survive drying or freezing conditions; the same property can help maintain the quality of beverages and supplements during processing and storage. Although trehalose occurs naturally in foods like mushrooms and honey, most commercial trehalose is produced enzymatically from starch, which allows it to be used consistently in formulated products.

Uses and Practical Notes

In the context of sports nutrition, trehalose shows up in some powders, gels and chews alongside other carbohydrates. A blend of trehalose and faster sugars can support steady energy output during long training sessions. Its mild sweetness and stability make it suitable for products that include vitamins, amino acids or probiotics that need protection from heat or moisture. Trehalose is also used in freeze-dried fruit pieces found in drink mixes because it helps preserve color and flavor. Outside of sports drinks, it appears in baked goods, sauces and even vaccines due to its ability to stabilize proteins and membranes.

A slow-digesting sugar like trehalose is not as common as glucose or sucrose in mainstream sports drinks, but it offers a way to deliver energy over time without making a beverage overly sweet. When paired with more rapidly absorbed carbohydrates, trehalose can contribute to a balanced fuel mix that supports endurance and product stability.
