Why Water, Electrolytes & Carbs Matter? The Science Behind Endurance Fueling.

Is plain water really enough during exercise, or could sugary sports drinks be doing more harm than good?


Why Water, Electrolytes & Carbs Matter?
  • Amateur runners: Experienced but lacking comprehensive nutritional planning.
  • Occasional runners: Unfamiliar with nutritional and pacing strategies, often relying only on water or random beverages.

Challenge 2: Insufficient electrolyte replenishment in commercial sports drinks

Most sports drinks in Taiwan still follow outdated electrolyte standards (CNS 12149 N5223, 1987) by the Bureau of Standards, Metrology and Inspection, M.O.E.A., failing to meet modern sports science requirements [12].

Common issues with commercial sports drinks:

  • Electrolyte concentrations are too low to adequately replace sweat losses.
  • Excessive sugar content raises osmotic pressure, reducing hydration efficiency and causing gastrointestinal discomfort.
  • Unpleasant taste lowers consumer acceptance.

Soonli’s Solution: Designed for Real Nutritional Needs and Great Taste

Our product design focuses on sufficient replenishmentoptimal absorption, and great taste, following these principles:

  • Hypotonic formulation to enhance rapid fluid absorption With human blood serum osmolarity around 300±30 mOsm/kg, our products are designed to match optimal hydration needs closely.
  • Multi-carbohydrate blend to improve intestinal fluid absorption Using a 2:1 glucose-to-fructose ratio, scientifically shown to enhance carbohydrate and fluid uptake while reducing gastrointestinal discomfort.
  • Evidence-based electrolyte levels to fully replace exercise-induced losses Electrolyte levels (Na⁺, K⁺, Ca²⁺, Mg²⁺) follow recommendations from the American College of Sports Medicine and Taiwan’s Ministry of Health and Welfare dietary guidelines.
  • Refreshing flavours - Cranberry, Grapefruit and Citrus Lemon

Conclusion: Optimal nutrition isn't just for professionals—you can achieve it too.

Professional athletes have teams to tailor their nutritional strategies, precisely matching fluid and electrolyte losses. However, most recreational athletes underestimate these needs.

We aim to provide more suitable, refreshingly tasty nutritional choices for all exercise enthusiasts. Effective replenishment not only boosts competitive performance but also makes exercise more enjoyable.
