MALTODEXTRINA
Also known as: Maltodextrin, Food Additive, Carbohydrate Supplement
Overview
Maltodextrin is a polysaccharide derived from starch, commonly from corn, rice, or potato. It is a white, odorless powder used as a food additive to improve texture and shelf life and in sports nutrition for energy supplementation. As a carbohydrate, maltodextrin has a high glycemic index, leading to rapid blood sugar spikes. Research on maltodextrin is extensive in food science and sports nutrition, but more studies are needed to fully understand its health impacts. It is produced from starches and is available in various forms, primarily as a powder. While generally recognized as safe, excessive consumption can lead to health issues like high blood sugar and insulin resistance. Some studies suggest potential benefits in exercise performance through mouth rinses, but the overall effect size is not well-quantified.
Benefits
Maltodextrin primarily provides a rapid energy source due to its high glycemic index, making it useful for athletes needing quick energy boosts. However, the quantified benefits in sports performance are mixed. Some studies suggest that maltodextrin-based mouth rinses may improve exercise performance by stimulating carbohydrate receptors in the mouth. A meta-analysis of 34 randomized controlled trials supports this. Athletes may benefit from its rapid absorption, but caution is advised due to potential blood sugar spikes. Resistant maltodextrin, a distinct form, may improve bowel movements, as shown in a systematic review and meta-analysis, but this benefit does not apply to the commonly used form in sports nutrition.
How it works
Maltodextrin is rapidly absorbed into the bloodstream, causing a quick increase in blood glucose levels. This rapid absorption primarily affects the digestive system and blood sugar regulation. It interacts with carbohydrate receptors in the mouth, potentially influencing exercise performance. The primary biological pathway involves the digestion of the polysaccharide into glucose, which is then used for energy. Its high bioavailability ensures quick energy delivery, making it a popular choice for athletes needing an immediate energy source.
Side effects
Maltodextrin is generally recognized as safe (GRAS) by the FDA, but excessive consumption can lead to adverse effects. Common side effects include rapid blood sugar spikes and potential gastrointestinal discomfort. Uncommon side effects may include effects on gut bacteria balance. Individuals with diabetes or insulin resistance should use it with caution due to its high glycemic index. It may interact with diabetes medications, exacerbating blood sugar control issues. Pregnant women and individuals with chronic health conditions should consult a healthcare provider before use. Excessive intake can contribute to insulin resistance and other metabolic issues. While rare side effects are not well-documented, it's essential to monitor blood sugar levels and overall health when consuming maltodextrin regularly.
Dosage
The minimum effective dose of maltodextrin is not well-established, but it is typically used in amounts of 20-80 grams per serving in sports nutrition. Optimal dosage ranges vary based on individual needs and activity level. There is no specifically defined maximum safe dose, but excessive consumption should be avoided. It is often consumed before or during exercise for energy. Typically, it is used as a powder mixed with water. Due to its high glycemic index, it is rapidly absorbed. No specific cofactors are required for its absorption or utilization. Individuals should monitor their blood sugar levels when using maltodextrin, especially those with diabetes.
FAQs
How much maltodextrin should I take?
The optimal dose varies, but it is often used in amounts of 20-80 grams, depending on individual needs and activity level. Start with a lower dose to assess tolerance.
Is maltodextrin safe for diabetics?
Maltodextrin can cause blood sugar spikes, so caution is advised for individuals with diabetes. Monitor blood glucose levels closely and consult with a healthcare provider.
When should I take maltodextrin?
Typically, it is taken before or during exercise for a rapid energy boost. Timing depends on the specific activity and individual response.
What benefits can I expect from maltodextrin?
You can expect a rapid energy boost due to its high glycemic index. However, be aware of potential negative effects on blood sugar control, especially with frequent use.
Is maltodextrin a complex carbohydrate?
No, maltodextrin is not a complex carbohydrate. It has a high glycemic index, meaning it is rapidly digested and absorbed, leading to quick blood sugar spikes.

- https://www.mdpi.com/2072-6643/16/18/3078 – This study investigated the effects of a mixed carbohydrate supplement containing maltodextrin and fructose on inflammatory markers. The study provides insights into the metabolic responses to carbohydrate supplementation, but specific outcomes related to maltodextrin alone were not detailed, limiting conclusions about its individual effects.
- https://examine.com/research-feed/study/1vGaa0/ – A meta-analysis of 34 randomized controlled trials found that maltodextrin-based mouth rinses may improve exercise performance by stimulating carbohydrate receptors in the mouth. This suggests that even without ingestion, maltodextrin can enhance athletic performance through sensory mechanisms.
