To achieve the effect, an average of 2.0 liters of water must be drunk per day.

Water contributes to the maintenance of normal physical and cognitive functions
Water contributes to the maintenance of the normal regulation of body temperature

Potassium tripotassium citrate monohydrate

Potassium contributes to the normal functioning of the muscles. Helps maintain normal muscle function and plays a role in maintaining strong muscles.
Has a positive effect and normal functioning of the nervous system. And further Potassium contributes to the maintenance of normal blood pressure

Extra information
Through intensive exercise you also lose potassium through sweating. Through Bron you immediately replenish this shortage and the potassium, together with chloride and sodium in Bron, ensures that the moisture balance immediately returns to an arrow.

Sodium and potassium therefore go hand in hand with each other.

This ingredient used is not on the (IOC / WADA) doping list and the health claim is pending European authorization



know as Branched-Chain
Amino Acids

A composition of 3 types of amino acids, namely L-leucine, L-isoleucine and L-valine. The body converts all the proteins you consume into amino acids. In Bron, all those transformed protein chains are in the best ratio of 4: 1: 1. The body constantly fluctuates between muscle building (anabolic) and muscle breakdown (catabolic). BCAAs help keep the body anabolic by being the building blocks of our muscle mass.

BCAAs prevent neurological fatigue by being used as the amino acid Tryptophan, which keeps the brain active.

Proteins contribute to the growth of muscle mass
Proteins, support rapid muscle recovery after training / sport (performance)
stimulates / promotes muscle growth / (fat-free) muscle mass (for sports)

Extra information
You do not have time to eat anything before exercising or during work? During your training you drink Bron Sport and while working you drink Bron Work where the BCAAs ensure that no muscle breakdown takes place. This also ensures that later in the day you get less of an “afternoon dip” where you are inclined to eat.

After an intensive first half hour of training you will notice that you are less focused, the BCAAs in Bron Sport ensure that you stay focused throughout your workout

Maltodextrin: fructose 2: 1

In other words carbohydrates in Bron Endurance

Maltodextrin is a carbohydrate that replenishes energy relatively quickly, but does not cause a peak effect in blood glucose. Ideal just before or during prolonged efforts.

Fructose is absorbed more slowly than other types of sugars.

Maltose consists of two units of glucose. When you add multiple units of glucose (maltose + dextrose), you get maltodextrin. Because we use different energy systems (ATP, anaerobic, aerobic) during exercise, you do not only burn on carbohydrates. This is often a combination of fat and carbohydrates.

Therefore, make sure that you have enough carbohydrates during exercise during exercise that lasts longer than 60-90 minutes.

You don’t need extra carbohydrates for anything up to 60-90 minutes. Then only use Source sport (0 Kcal).

Maltodextrin: Consists of complex polymers. Tastes moderately sweet and is built in the same way as starch, but contains less glucose particles per polymer. This makes it more quickly absorbed by the body
Structure of maltodextrin: 2% free glucose 7% maltose (two linked glucose molecules) 91% longer chains of glucose.
The ideal composition and absorption for the body between maltodextrin and fructose is 2: 1.

In addition to the intensity and duration of the training, the outside temperature is also important when choosing your sports drink. When it is very hot, you lose more moisture. To complement that, it is best to choose a drink with a low carbohydrate concentration. When it is colder, the moisture loss will be less and you will use a little more carbohydrates. You can also let the temperature of the drink depend on the outside temperature. With warm weather you prefer a cool drink, in cold weather prefer a hot drink.

With Bron Endurance you can therefore decide for yourself how strong you want your sports drink.
