On the question about picking the optimum moment to drink Purition in relation to your exercise regime, there’s really no magic ‘window of opportunity’ that maximises Purition’s effectiveness, because great nutrition is never about quick-fixes, but what gets eaten over a 24-hour time-frame. That said, in an ideal world, we’d advise that you consume your shake at least 1-2 hours before exercise. However, if your preference is to have your Purition shake post-workout, we would recommend waiting until you get back home or from the office when you can prepare it properly and truly enjoy it.
