Description

The redesigned EFS formula uses a 2:1 glucose to fructose carbohydrate ratio, helping deliver immediate and sustained fuel while supporting easier digestion during longer efforts. Its isotonic profile is designed for rapid rehydration, helping replace fluids and key electrolytes lost through sweat.

Unlike many standard drink mixes, EFS delivers all five key electrolytes, including sodium, potassium, chloride, calcium and magnesium. This helps support hydration, reduce the risk of cramping and keep your body performing when sessions get hot, long or demanding.

With no artificial flavours, colours or sweeteners, EFS is made for athletes who want a clean, effective and easy-to-use drink mix. It is ideal for training, racing, topping up before an event or staying fuelled during long endurance sessions.

How does it work

EFS works by combining fast and sustained carbohydrate sources with a full electrolyte profile to support endurance performance. The 2:1 glucose to fructose ratio uses multiple transportable carbohydrates, helping the body absorb more fuel during exercise while reducing the risk of stomach discomfort.

Its isotonic formula is designed to support fluid absorption and hydration, while sodium, potassium, chloride, calcium and magnesium help replace what is lost through sweat. This makes EFS useful for maintaining energy, supporting hydration and reducing the risk of cramping during longer or more intense sessions.
