Rondos Jelly and Foam Gums by Woolworths has 66 kcal, 15 g carbs, 1.6 g protein and 0.1 g fat per serving (Per 25 g serving).
Woolworths Rondos Jelly and Foam Gums are a high-sugar confectionery product, providing 15 g of carbohydrates per 25 g serving, predominantly from sugars. These brightly colored, ring-shaped gums are designed for quick energy release, making them suitable for endurance athletes needing rapid carbohydrate intake during prolonged exercise. With minimal fat and protein content, they focus on fast-acting energy rather than sustained release or recovery support. Ideal for mid-session fueling, they can help maintain blood glucose levels during high-intensity or extended workouts. However, their high sugar content may not be suitable for all athletes, especially those sensitive to sugar spikes.
- Quick carbohydrate source
- Minimal fat for fast digestion
- Convenient for mid-session fueling

The numbers that matter on a training day
For endurance who it suits
Rondos Jelly and Foam Gums offer a quick and convenient carbohydrate source for endurance athletes needing fast energy. However, their high sugar content may not be suitable for all, particularly those prone to sugar spikes or gastrointestinal distress. They are best used during high-intensity sessions where rapid energy replenishment is needed.
These jelly gums are best suited for endurance athletes such as marathon runners, cyclists, or triathletes who require a quick source of carbohydrates during training or competition. They are particularly useful for those who have trained their gut to handle simple sugars during exercise. Athletes with a high tolerance for sugar intake will benefit most from this product.
Ideal for high-intensity interval training, long-distance cycling, or marathon running where quick energy replenishment is crucial. Not recommended for recovery or low-intensity sessions due to high sugar content.
- High carbohydrate content for quick energy
- Low fat content aids rapid digestion
- Convenient and portable for workouts
- No allergens listed, broad suitability
- High sugar content may cause spikes
- Limited electrolyte contribution
- Not suitable for recovery due to low protein
- Potential for gastrointestinal distress if unaccustomed
- High sugar can contribute to dental erosion
Fuelling science in short
Yes, consume one serving every 30-45 minutes during intense exercise for quick energy. Conveniently portable and non-messy.
High glycemic index due to sugar content, leading to rapid blood glucose spikes. Quick gastric emptying supports fast energy availability.
Contains 3 mg sodium per serving, negligible compared to typical sweat losses of 300-600 mg/hr. Not a significant source of electrolytes.

Pre-race use is not advised due to potential blood sugar volatility and GI distress. During race, they provide quick energy but should be consumed within gut absorption limits. Post-race, they lack necessary nutrients for recovery. Not suitable for carb loading due to high sugar and low complex carb content. Use cautiously in everyday training to avoid excessive sugar intake.
NOT RECOMMENDED for pre-race use because the high sugar content may cause blood sugar volatility and potential gastrointestinal distress if consumed in large quantities.
USE during racing for quick energy. Consume one serving every 30-45 minutes, ensuring not to exceed gut transporter capacity.
NOT RECOMMENDED for recovery because it lacks sufficient protein and complex carbohydrates necessary for effective glycogen replenishment and muscle repair.
- Pair with electrolyte drink for sodium balance
- Combine with protein post-exercise for recovery
- Use alongside complex carbs for sustained energy
For practitioners the evidence
Evidence grade: B — Supported by sports nutrition literature on carbohydrate intake and absorption, but lacks direct RCT evidence specific to this product.
Rondos Jelly and Foam Gums have a high carb density of 58 g per 100 g, but their serving size of 25 g limits their contribution to carb loading. A single serving provides 15 g of carbs, contributing minimally toward a 600-840 g daily target for a 70 kg athlete. Consuming the required number of servings would be impractical due to high sugar content and potential GI distress. Therefore, these gums are unsuitable for effective carb loading.
Upon ingestion, the sugars in Rondos Jelly and Foam Gums are rapidly digested and absorbed in the small intestine. The glucose is absorbed via the SGLT1 transporter, while fructose, if present, would be absorbed via GLUT5. The rapid gastric emptying due to low fat content facilitates quick entry into the bloodstream, leading to a swift insulin response. Any unabsorbed sugars may undergo fermentation in the colon, potentially causing GI discomfort if consumed in excess.
These gums provide a quick carbohydrate source but lack protein and complex carbohydrates necessary for effective post-exercise recovery. Glycogen resynthesis requires 1.0-1.2 g/kg/h of carbs, and muscle protein synthesis needs leucine and total protein intake, neither of which are adequately provided by this product. Without sufficient protein, they fail to support muscle repair or adaptation.
High sugar content can lead to dental erosion due to prolonged exposure and acidic pH. Excessive consumption may cause blood glucose spikes, leading to rebound hypoglycemia. The absence of significant electrolytes makes them unsuitable for rehydration. High sugar intake without gut adaptation may result in gastrointestinal distress.
- Do not use within 90 minutes of race start if unaccustomed to high sugar intake.
- Avoid during recovery as they lack protein and complex carbs necessary for muscle repair.
- Do not use for carb loading due to high sugar content and low complex carb presence.
- High sugar intake may cause rebound hypoglycemia post-exercise.
- Excessive sugar can lead to dental erosion with frequent use.
- Fructose without glucose co-ingestion may exceed GLUT5 capacity, causing GI distress.
- Low sodium content is inadequate for replacing sweat losses in endurance athletes.
