The US-headquartered Clif Bar & Company has moved into the UK market with its Clif® Bar energy bars and Clif Shot Bloks® electrolyte chews (pictured).

Designed to provide sustained energy before, during and after exercise, the products contain a combination of carbohydrates, protein and fibre.

Clif Bars are available in three flavours - chocolate chip, oatmeal raisin walnut and crunchy peanut butter - with a mixture of rolled oats, nuts and soya and various vitamins and minerals.

The Shot Bloks meanwhile, contain both simple and complex carbohydrates, sodium to maintain hydration and potassium to prevent muscle cramping. They are designed to be eaten three at a time at a total of 100 calories.
