Review summary
Science in Sport Beta Fuel Energy Drink Mix is a carb/electrolyte drink mix (80 g carbs/serving; no caffeine). Dual-source high-carb powder (~80g carbs per labeled serving) — designed for bottle-based race fueling when you want SiS Beta Fuel continuity between gel and drink formats. I'd shortlist it for high carb dose aligns with Beta Fuel gel race plans.
The trade-off is sweetness can fatigue vs Maurten’s milder profile — Maurten Drink Mix 320 is the cleaner compare when that is most of your week. It fits buyers who actually need a carb/electrolyte drink mix (80 g carbs/serving; no caffeine), not a one-product rotation.
