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.

Got a big kick out of these gels
The caffeine enriched version is really great on those early morning rides where you don't get the chance for a caffeine boost at your local cafe before the ride. I like to use the caffeine gel after an hour or so on the road to get a mental kick, and just use the regular gels in between. Nutrition and exercise science tells us the caffeine also helps to metabolise and release all our energy reserves. Who's to argue! Seems to work really well.
SiS Go + Caffeine Energy
Excellent product from SIS. Easy to use gel. The structure and texture of these SIS GO + Coffeine is light, very good taste, not sticky.
SiS Gels are one of the best choices for anyone racing. I've tried a lot of brands and many of them are either too sweet or too thick and not really conducive to hard racing when you just want to get a gel down quickly and get on with it. For both shorter and longer rides, these larger volume gels also offer more liquid than any other gel, perfect for 2yr cross/endure races or longer road crits. Regards, Mark
