Energy gel delivering 87 kcal per serving, primarily from 22 g fast‑acting carbohydrates, with very low sugar and salt, sold in multiple flavours and pack sizes.
+ Low sugar (0.6 g) across the range – suitable for athletes seeking a sugar‑controlled fuel. + All ingredient doses are fully disclosed, offering clear transparency. + Available in single‑serve, multi‑pack and trial sizes, giving flexibility for training or race day. + Larger packs generally provide better value per serving.
- Contains no protein or fat, so it won’t contribute to recovery nutrition on its own. - Very low in electrolytes; athletes with high sweat rates may need additional salt.
This gel family is positioned as a pure carbohydrate source for endurance sports such as running, cycling and triathlon, with a consistent 87 kcal, 22 g carbohydrate profile per scoop and minimal sugar (0.6 g) and salt (0.01 g). The formulation is identical across flavours, differing only in taste and packaging; all doses are openly listed. While the base gel is sugar‑free and convenient for quick energy, its lack of protein and electrolytes means it should be paired with other recovery or electrolyte products for longer sessions. Larger multi‑packs tend to be more cost‑effective, and trial‑size options let users test flavours before committing.
