Our Science

At myDNA, we help people understand the secrets of their DNA and what to do with that knowledge.

Our quest is to eradicate guesswork for our customers

Associate Professor Les Sheffield, who has been at the forefront of genetic research since the 1980s, founded myDNA in 2007 with the quest to eradicate guesswork of prescribing medication. Since then, myDNA has diversified as the personalised health and wellness revolution has grown. Our heritage is in the science, and is at the core of what we do every day.

We’re passionate about turning DNA insights into action

With myDNA products, everyone can be their best possible self and live life to the fullest. We give our customers easily understood, relevant and applicable action plans to turn their DNA insights into action. But what we do in the background involves months of work, collaborating with nutrition and fitness experts to develop personalised fitness and meal plans with thousands of combinations and permutations.

Evidence Rating System ensures our recommendations are backed by science

We pride ourselves on giving our customers recommendations based on evidence-based, peer-reviewed research. Our recommendations are based on the rigorous review of all current scientific literature. Our list of references is constantly growing as our team of clinical experts assess and use international research with the strongest evidence.

We have developed an evidence rating system that explains the quality of the relevant DNA insights we provide. This is based on Oxford Centre of Evidence Based Medicine – Level of Evidence, March 2009 (modified by myDNA to apply for genetic tests). Both interpretation and recommendations have been assessed for evidence ratings.

Our team of scientific experts

Our clinical team includes pharmacologists, molecular and clinical geneticists, researchers, genetic counsellors, nutritionists and dietitians. Between them, we have over 120 years of experience, and a wealth of experience.
