Hydration and endurance · Answer
32Gi is a South African endurance brand and was the official gel and energy-bar supplier to the 2024 Comrades Marathon. Its High Intensity Gel costs R25–R35, but carbohydrate and caffeine per gel are not published on the retailer pages we checked, so it cannot be compared per gram. Biogen, SiS and Maurten publish more detail.
On what we could verify in October 2026, 32Gi competes on brand presence and local availability rather than on published nutrition detail. The retailer pages we reviewed list the 32Gi High Intensity Gel (27 g) as brown rice syrup with salt, but do not give carbohydrate grams or caffeine per gel. That means we cannot calculate Rand per 30 g of carbohydrate for it.
| Gel | Carbs per gel | Price (retailer) | Notes |
|---|---|---|---|
| 32Gi High Intensity, 27 g | not published | R25–R35 | brown rice syrup, flavouring, salt; coffee flavour exists |
| Biogen Elite Carb, 60 g | 45 g | R44.99 (Dis-Chem Living Fit) | maltodextrin and fructose; caffeine not stated |
| Biogen Perform-X, 36 g | 26 g | price not shown | electrolytes; caffeine-free |
| Biogen Liquid, 60 ml | 23 g | R26.99 (Biogen shop) | 29 mg sodium; caffeine-free |
| SiS GO Isotonic, 60 ml | 22 g | R44.90 (Sportsmans Warehouse) | caffeine-free |
| Maurten Gel 100, 40 g | 25 g | R74–R75 | fructose:glucose 0.8:1; 20 mg sodium |
| Maurten Gel 100 CAF 100 | 25 g | R80–R85 | 100 mg caffeine |
Brown rice syrup is a glucose-based carbohydrate, and we saw no fructose in the gel's ingredient list. Glucose-only absorption tops out at roughly 60 g an hour, while glucose-plus-fructose blends allow up to about 90 g an hour (Jeukendrup 2014). That is our inference from the ingredient list, not a claim from 32Gi. If you plan to take more than about 60 g an hour, combine the gel with a glucose-plus-fructose drink such as 32Gi's own race drink, or use a different gel.
