How to use it, by distance
For a 5k, this drink might not be necessary mid-race due to its short duration. However, consuming it 30 minutes before the start can help top off glycogen stores.
Consume 1 serving 30 minutes before the race to ensure glycogen stores are maximized. This can help maintain energy levels throughout the race.
Consume 1 serving 30 minutes before the race. During the race, consider taking a serving at the 10km mark to maintain energy levels and hydration.
Start with a serving 30 minutes before the race. During the marathon, aim for a serving every 45 minutes, starting at the 10km mark. This provides consistent energy and helps maintain hydration levels. Pair with water to manage osmolality and prevent gastrointestinal distress.
The science in short
Ideal for medium-distance events where rapid energy and hydration are crucial.
Isotonic — Designed to match the body's natural fluid osmolality, promoting quick absorption without causing gastrointestinal distress, ideal for maintaining hydration and energy levels during intense efforts.Rapid Energy - Isotonic Sports Drink offers a reliable and cost-effective solution for athletes seeking quick energy and hydration during medium-distance events. Its multi-source carbohydrate blend ensures efficient absorption, while the isotonic formulation supports rapid gastric emptying. However, the need for multiple servings to meet higher carbohydrate demands and the high sugar content may not suit all athletes. Overall, this product is a solid choice for those prioritizing value and performance in short to medium endurance activities.
The 2:1 glucose-to-fructose ratio facilitates dual-pathway carbohydrate absorption via SGLT1 and GLUT5 transporters. This maximizes the rate of carbohydrate oxidation, enhancing endurance performance. The isotonic nature ensures rapid gastric emptying and efficient fluid absorption, critical during high-intensity efforts.
While effective for medium distances, the need for multiple servings can be cumbersome for longer events. The high sugar content may also pose a risk for athletes sensitive to sugar spikes.
Each 20g serving provides 18.7g of carbohydrates, making it a cost-effective option for athletes needing sustained energy.
0.935g per gram — higher than many competitors, offering efficient energy delivery.
Multi-source (2 carbs: Maltodextrin, Fructose). Uses both SGLT1 and GLUT5, supporting up to ~90 g/h.
Maltodextrin — glucose pathway (SGLT1); Fructose — fructose pathway (GLUT5)
Contains 139mg sodium and 50mg potassium per serving, addressing basic electrolyte needs but may require supplementation for heavy sweaters.
2:1 — multi-source blend lifts the absorption ceiling beyond SGLT1's 60 g/h.
3 servings/hr = 56.1g carbs, slightly below 60-90g/hr optimal range.
- Monitor sugar intake if sensitive to high sugar levels.
- Ensure adequate water intake to maintain isotonic conditions.
