SIS GO + Caffeine Gel 60ml


The latest innovation from leaders in sports nutrition Science in Sport.

Smart 1 Gel combines our unique GO-Gel technology to deliver energy with a whole host of extras.

Imagine a caffeine kick helped along with blood that flows easier, down even the smallest capillaries, delivering more nutrients and stimulation to active muscles.

Caffeine to give you that extra stimulation.

Blackcurrant anthocyanins, a potent antioxidant, for improved night vision - great for drivers and night events. High Caffeine levels are often associated with a blurring of vision and these anthocyanins may reduce this.

Citrus Bioflavenoids, another powerful antioxidant, has been shown to improve caffeine absorption, and work synergistically with the other antioxidants.

Together these functional ingredients will improve blood flow, protect against oxidative stress, improve night vision, improve alertness and reduce cramp and muscle strain.

All this functionality crammed into a great tasting berry flavour gel.
