Maltodextrin - maltodextrins are glucose polymers obtained from controlled enzymatic digestion of corn starch or potatoes.

The various glucose units are linked together by characteristic alpha 1-4 glycosidic bonds, which are easily recognized and cut from salivary and pancreatic amylases. The monosaccharides originated from the digestion of maltodextrins, are absorbed by the border of brushes of the enterocyte, through a sympathy with sodium, while they are released basolaterally in the circulatory stream through a specific transporter, also belonging to the family of GLUT (glucose transporter) . The digestion and absorption times of these macromolecules vary according to their complexity; it is no coincidence that an important reference parameter is used, known as DE (dextrose equivalence). This fact correlates with the chemical complexity of maltodextrins, therefore also with the timing and methods of absorption. It is important to consider that low DEs represent maltodextrins with long digestion and absorption times, while high DEs are relatively simple and easily digestible polysaccharides.

The advantages that come from taking maltodextrin supplements, compared to naturally occurring carbohydrates are:

1. Faster digestion times: important for the sportsman, to avoid reduction of blood flow in the muscles and brain;
2. Choice of maltodextrins with a different DE: allows an integration studied based on athletic performance;
3. Polymeric chains of glucose molecules linked together through an alpha 1-4 glycosidic bond, of different lengths, obtained by controlled digestion of corn starch.

The biological role of these molecules can be totally superimposed on that of carbohydrates; therefore, maltodextrins can be effectively used by athletes as:

• Ergogenic help before performance;
• Energy support during the performance;
• Promoter of restoration of post-training glycogen stocks;
• Anabolic stimulator;
• Water-based reintegration adjuvant, when used in iso and hypotonic beverages.

Rationale - Maltodex - ProAction

All the aforementioned applications can be realized thanks to a well studied and tested integrative protocol. On the other hand, excessive or incorrect supplementation results not only in the absence of these results, but above all in the onset of long and short-term side effects. In this regard, the following table summarizes the advantages and risks obtainable respectively with a correct or incorrect supplementary protocol.

PRO		VERSUS
Saturation of muscle glycogen levels		Reactive hypoglycemia before performance
Ergogenic help and support for performance		Decline in cognitive abilities
Restoration of muscle glycogen stocks		Decline in athletic ability
Anti-catabolic effect during performance		Overweight, obesity and associated diseases
Post work-out anabolic effect
Hydro-salt reintegration

In light of the various studies, it is therefore necessary to carefully weigh the supplementary protocol and test it in training before athletic performance.

Maltodextrin and performance improvement: the improvement of athletic performance, following supplementation with maltodextrin and more generally with carbohydrates, seems not to be attributable exclusively to their metabolic-energetic role. Several studies are characterizing the motivational aspect linked to the improvement of athletic performance, which seems to be supported also by a mechanism that sees the participation of the "sweet" receptors allocated in the buccal cavity. This could represent an added value to the energy properties of maltodextrins.

Product Features Maltodex - ProAction

The product in question has maltodextrins with dextrose equivalence equal to 18, thus representing a valid compromise between simple digestion carbohydrates and energy source available for medium-long intervals.

Recommended use by the company - Maltodex - ProAction

Dissolve 53 grams (5 heaped tablespoons) of product in 500 ml of water or any other beverage.

Use in sports - Maltodex - ProAction

The method of use suggested by the company involves the formulation of 10% maltodextrin-based drinks. Several studies, however, found better absorption profiles and greater tolerability for concentrations reduced to 6.4%, ie by diluting the 53 g of maltodextrin in 830 mL of water.

Defining a universal dose that is valid for everyone is impossible, as it inevitably takes into account the nutritional status of the subject, the type of diet, the type of sport, its duration, its intensity and the objective to be achieved.

Generally for endurance sports, exceeding 90 'is recommended to use 30 grams of maltodextrin for every hour of training, while in post-work out recovery, the best stimulus in terms of muscle glycogen resynthesis is obtained with 1 gram of carbohydrates per each kg of body weight

Synergies

Maltodextrin + proteins: in the recovery phase, it could be useful in improving the anabolic window.

Maltodextrin + mineral salts: fundamental for the reintegration of salt water, if formulated in a hypo and isotonic drink.

Maltodextrin + arginine: it strongly enhances glycogen synthesis compared to maltodextrins only;

Maltodextrin + fructose: improves muscle oxidation of ingested carbohydrates compared to the administration of maltodextrin alone;

Maltodextrin + amino acids: before training, it significantly reduces muscle damage, supporting performance and reducing plasma levels of cratinkinase.

Maltodextrin + antioxidants: they can reduce the oxidative damage induced by intense physical exercise.

Maltodex - ProAction side effects

The side effects that may occur following the incorrect administration of maltodextrins can be short or long term.

In the short term, problems can usually occur in the gastrointestinal tract, with abdominal cramps, diarrhea, nausea and vomiting.

The long-term effects, on the other hand, could be compared to those obtainable with excessive nutrition, rich in simple carbohydrates (overweight, obesity and related pathologies).

Precautions for use Maltodex - ProAction

The product is contraindicated in cases of renal or hepatic disease, cardiovascular disease and / or hypertension, during pregnancy, during lactation and under 14 years.
