Stephanie Drax

Stephanie is a journalist and a mother to two small tornado-like boys. Like many mums, she would brace herself for the winter months when the inevitable blocked noses and spluttering coughs would start. In 2018, Stephanie began researching ways of cutting colds off at the pass rather than masking the symptoms with medication. A nutritionist, Anna Moore, suggested better gut health as part of the solution, and Stephanie wrote an article about it. Her research led her to Dr Nicholas Larkins, who told her about lactoferrin and its extraordinary properties. He himself had written a paper on it, contributing to the growing scientific research on lactoferrin’s potential therapeutic benefits. Stephanie was sold on its instant anti-viral efficacy and hasn’t looked back since.
