Science in Sport Protein Bar

£40 (20 bars), scienceinsport.com

Utilising a three-part blend of casein, whey and soy protein, these bars chuck everything at your muscles to kickstart growth. An equal split of 20g protein and 20g carbs aid both repair and energy, and the texture is pleasantly chewy without being too claggy. Chocolate & Peanut or Mint Chocolate are your flavour choices, and there are 219 calories per bar.
