Ph D Fitness Overview The Clif Shot range is all about energy on the go, designed specifically for the athletes & enthusiasts pushing themselves hard who require a easy simple form of digestible carbohydrate. Clif Shot Bloks are energy chews, little bite size cubes of concentrated energy. 3 Bloks provide the same amount of carbohydrate as 1 Clif Shot Gel. Each Clif Shot Bloks pack contains 6 Bloks (2 servings). They are the perfect quick easily digestible alternative to gels & are a much loved favourite with both triathletes & runners. Not just full of sugar Clif Shot Bloks use a 50/50 ratio of simple to complex carbohydrates which provides both a short term kick & long term sustained energy release. Clif Shot Bloks also contain essential electrolytes to help replenish some of those lost through exercise. Tropical & Orange Clif Shot Bloks also include caffeine which can give that extra boost when concentration is decreasing & fatigue is starting to set in.
