All about intra-workout supplementation

General Information

The term "intra-workout supplementation" refers to the intake of supplements during training. In addition to pre- and post-workout supplementation, which is taken for the supply of nutrients before and after training, intra-workout supply has also become increasingly important in recent years. Especially during longer training units successful athletes meanwhile resort to Intra-Workout Supplements, which provide a specific supply of key substrates during training. If you too have neglected this phase so far, we recommend to deal with the optimal nutrient supply during training to optimize your training results.

When is an intra-workout supply useful?

In which cases an intra-workout supply becomes especially important depends primarily on the following factors:

  • Pre-Workout supply
  • Training lenght
  • Training intensity
The supply requirement in training is largely dependent on the nutritional supply before training. The longer the last solid meal is ago, the more important intra-workout nutrition becomes. Of course, the immediate pre-workout supply also plays a decisive role here. In situations in which the intake of a solid pre-workout meal and/or pre-workout supplementation is not possible (e.g. during early morning training), a fast intra-workout supply closes decisive supply gaps. Another decisive criterion is the length of the training. In training units which, due to their length, have consumed important key substrates and therefore result in a lack of nutrients towards the end of the unit, the athlete can benefit from a supply of intra-workout supplements. This is especially true for athletes who do cardio training on a bike, treadmill, crosstrainer or other cardio equipment after their strength training. While an intra-workout shake can be regarded as superfluous in a 15-minute cardio session, for example, the nutritional supply in such a case becomes immensely important, as this usually results in a training length of up to two hours (sometimes even longer). Such a long training duration considerably increases the risk of a deficiency supply, which can result in the body having to use the hard-earned muscle protein.

Some of the most proven and popular substrates that are taken during exercise in the form of an intra-workout shake include:
  • BCAAs
  • Creatine
  • EAAs
  • Glutamine
  • Carbohydrates
  • Nitric Oxide (N.O.) Precursors


BCAAs are vital branched-chain amino acids consisting of L-leucine, - L-isoleucine and L-valine. As the above-mentioned representatives are essential amino acids which the human organism cannot synthesize on its own, it is dependent on a supply through nutrition. BCAAs have always had a firm place in sports nutrition, and L-leucine in particular should be emphasized here as the key amino acid of modern sports nutrition. Especially fitness and bodybuilding athletes, who are on a calorie-reduced diet and in this phase place special emphasis on muscle maintenance, increasingly rely on supplementation with BCAAs. But also endurance athletes, like triathletes or runners, rely on a fast BCAA supply, which is possible with a training drink. BCAAs in Total Solution Technology are particularly suitable for this purpose, as they penetrate the blood pool extremely quickly and effectively due to their resorption properties. The especially fast absorption enables the amino acids to reach the extracellular cell tissue after only 10 minutes to fulfil their functionality.


Creatine is known as an organic acid, which exists mainly in meat and fish. As an important component of ATP synthesis, creatine is scientifically proven to increase physical performance. For this reason, creatine is indispensable in modern sports nutrition. The effect of the performance increase occurs during short-term intensive stress in the context of high-speed strength training from a daily consumption of 3g. This underlines the importance of taking creatine not only on training days but also on non-training days. Although the human organism is able to synthesize creatine in the liver, kidneys and pancreas, this amount is usually not sufficient for the needs of an intensively trained athlete. Due to its undoubtedly proven performance-enhancing effect, creatine is therefore used in many all-in-one intra-workout supplements.


EAAs are essential amino acids that the human organism cannot produce on its own. This means that EAAs have to be taken in with food. The amino acids L-phenylalanine, L-tryptophan, L-threonine, L-lysine, L-valine, L-methionine, L-leucine and L-isoleucine are classified as essential. L-arginine and L-histidine are also essential for teenagers and adolescents. However, since these amino acids are no longer essential for adults, they are classified as semi-essential. EAAs play a crucial role in building proteins, which in turn have been shown to help build and maintain muscle mass. Therefore, especially the performance-oriented athlete should rely on a sufficient supply of EAAs. For a targeted intra-workout supply, EAA TST, which, like BCAA TST, convinces with an extremely fast absorption speed, which is made possible by Total Solution Technology.


Glutamine is one of the most important amino acids in the diet of performance-oriented athletes. Glutamine is involved in many bodily functions and also functions as a proteinogenic amino acid as a building block of human protein. Furthermore, glutamine is the amino acid that is most abundantly stored in human muscles. Although glutamine is not essential as an amino acid, under certain circumstances a deficiency can occur. Such a deficiency symptom can occur, for example, in stressful situations (illness, dietary phase, or during high-intensity training). Conventional glutamine, however, has a suboptimal absorption capacity, as about 90% of it is metabolized directly in the liver. Thus, only about 10% of the intake quantity reaches the extracellular muscle tissue. The resorption rate can, however, be significantly increased by sublingual intake, where the glutamine is placed under the tongue where it should remain for as long as possible. Special glutamine compounds, on the other hand, are considered to be extremely bioavailable and are therefore ideal for being absorbed by the body particularly well.


Carbohydrates, along with protein and fat, are among the three macronutrients and are generally known as energy sources. Intra-workout nutrition is particularly well suited to quickly available carbohydrates, which are absorbed into the bloodstream shortly after they are consumed. Maltodextrin fulfils this property and provides energy quickly. Maltodextrin is a combination of monosaccharides, disaccharides and polysaccharides that provide energy quickly and are therefore ideal for use in training. This makes Glucofast ideal for ensuring a fast carbohydrate supply during training. Depending on the length of your training session and your nutritional situation and goals, you can determine how many carbohydrates you want to consume in order to be optimally and individually supplied. The tasteless Glucofast is also ideal for functional combination with amino acids such as BCAAs or EAAs.

Nitric Oxide (N.O.) Precursors

Nitric Oxide precursors are substances that are known as precursors of Nitric Oxide. They also include substrates that are considered synergy substrates of these precursors. Nitric Oxide acts as a messenger substance, which has a key role in vasodilatation. Especially the amino acids citrulline and arginine as well as its biogenic amine, agmatine sulphate, are known and extremely popular in modern sports nutrition in connection with Nitric Oxide.
Beside these single substrates there are also different all-in-one intra-workout supplements available, which are especially adapted to the time window in the training. The substrates listed above play a central role in the composition of these supplements.  The advantage of these complex formulas is that the recipes are put together by an expert hand. This is of particular benefit to athletes who are inexperienced or have little experience in the effective combination of various substances in sports nutrition.

Intra-Workout Supplements in sports

While Intra-Workout Nutrition was given little or no importance a few years ago, it is now an integral part of modern sports nutrition. Beverage mixes enriched with amino acids, carbohydrates and other substrates have long since replaced the pure fluid supply with water. Intra-workout supplements are therefore used in numerous sports, with bodybuilding, fitness and endurance sports being particularly noteworthy. Especially in endurance sports athletes appreciate the fast and uncomplicated absorption of nutritive and building substrates via a training drink which is also easily digestible and does not burden the body. This is a decisive advantage, because the consumption of solid food, e.g. in the form of an energy bar, would be rather counterproductive at this point in time, as energy is needed for digestion, among other things. A large selection of Intra-Workout Supplements also enables the performance-oriented athlete to ensure an individual supply, which thus supports the personal performance in the best possible way.

Use and side effects

Intra-workout supplements should be prepared in good time before the start of the workout, so that you only have to make sure in the gym that you mix your training drink with water or take the supplements. Ideally, you should consume your training drink in sips over the entire training period in order to ensure a constant supply situation.
In spite of an intra-workout supplementation, we generally advise you to take a post-workout shake after training, as a nutritive training supply is not able to replace the post-workout supply.
As a rule, no side effects are to be expected from the use of Intra-Workout Supplements within the scope of the respective consumption recommendation.

* As far as creatine is included, because 3g creatine daily increases the physical performance during high-speed training in the context of short-term intensive physical activity.
