HEALTHSPAN ELITE WHEY PROTEIN ISOLATE

£34.99, healthspan.co.uk

This is the purest whey protein on the market, with 90 per cent protein content (32g per serving), plus 7.5g BCAAs, as well as added vitamins and minerals to aid protein synthesis. The downside is that you have to add your own ‘flavour drops’, making it slightly more faff than conventional shakes; the upside is you’ll be treating your muscles to the very best in post-workout recovery.
