Gwen has helped me to understand the benefits of supplementation and that by tweaking my diet I can maintain the energy levels that I need during my high intensity sessions.  Gwen is an absolute pleasure to work with and even when she makes small changes to my diet I notice huge changes in my energy levels and feel sharper in the ring.

Gwen went out of her way to provide me with the unique advice that I needed for my body to cope with the ongoing high training loads I put it through in my chosen sport. I am not yet at a level of athletic significance, although she was always more than happy to offer her professional assistance, knowledge and guidance whenever I chose to seek it. Gwen has a unique kind-hearted nature and helped me reach an athletic level in less than a year that I thought would take me two or three. And for that I will be always be grateful. Onwards and upwards!

Gwen helped me throughout my professional rugby career in Australia. Not only did she help me lose the extra kilos I was carrying but with her support and advice I was also able to maintain my muscle mass, strength and energy level, which helped me on the field.
