Grenade Reload Protein Oat Bar

£1.99 (per bar), grenade.com

A delicious combination of nuts and oats, each 70g bar is presented in two handy 35g portions, making it ideal for an energy boost pre- and post- workout. Eat both at once and you’ll get a sizeable 17g protein and a whopping 7.4g digestion-assisting fibre (and just 2.2g sugar). Slow-release oats also make these a handy option for a grab-and-go breakfast as well as a post-workout snack. The bars are available in three flavours: Billionaires Shortbread, Chocolate Chunk and Blueberry Muffin.
