SiS GO + Caffeine contains 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. Also present are citrus bioflavenoids, another powerful antioxidant, which have been shown to improve caffeine absorption, and work synergistically with the other antioxidants.

Excellent product from SIS. Easy to use gel. The structure and texture of these SIS GO + Coffeine is light, very good taste, not sticky.
