Carbohydrates (2:1:1.5) 45 gr.

Since carbohydrates are the main energy source during exercise, the main ingredient of our during sports supplement should be carbohydrates. 02 During contains a mixture of different carbohydrate sources as this enables athletes to absorb and burn more fuel during exercise. Under normal circumstances, glucose uptake is limited to approximately 60 g per hour. The intake of multiple carbohydrate sources, like fructose, elevates carbohydrate absorption in the intestine up to 90 g. per hour. Furthermore, the use of multiple carbohydrate sources makes GI issues to be a thing of the past.
The ratio maltodextrin:glucose:fructose of 2:1:1.5 has been shown to elevate the rate of appearance of systemic glucose/lactate compared to the isocaloric amount of glucose only.

Electrolyte: Sodium (NaCI) 870mg.

Sodium is the main electrolyte lost in sweat and the only electrolyte to enhance performance during exercise. Other electrolytes (potassium, calcium, magnesium) are also lost in sweat, but in minimal quantities. A healthy diet is needed to keep these electrolyte concentrations at desired levels in the body.
The recommendation is to consume a sports drink with 0.5 – 0.7 g/L 59 sodium for shorter than three hours and 0.7 – 1 g/L sodium for exercise sessions lasting longer than three hours. In 02 During, we suggest adding a sodium concentration of 0.7 g/L. To one serving of 49 g, 620 mL of water should be added, so one serving should contain 0.35 g of sodium. It is strongly suggested to add sodium in the form of NaCl. One serving, therefore, contains 870 mg of NaCl salt.


Losing too much fluid through sweat can lead to dehydration, which can affect performance and potentially lead to more serious health problems. It is important for athletes to stay hydrated by drinking fluids before, during, and after activity.

Dehydrating can cause cramping and impaired performance if an athlete is not properly hydrated during their workout. Make sure you mix 02 During with enough water, preferably 600 ml.
