Claire Harper is the founder of the Greater Manchester-based business, which is the parent company of Muscle Moose and Smartshake. Following a period of rapid growth over the past 18 months, Muscle Moose products are now stocked across the UK, Canada, Europe, Middle East and New Zealand.

Muscle Moose began life as a sports nutrition company, in an industry that has always been and is still very much male dominated, with only one other female co-founder of a sports nutrition company in the UK.


GBEA is a community that really does work to the benefit of everyone involved. Something you don’t realise, even being in business yourself, is just how many incredible British businesses there are and we should be sharing success stories and championing those getting out there and doing it more – and that’s exactly what GBEA does.
