Life-changing moments

"An endometriosis client was bedbound by PMS. She had tried everything, including surgery, and finally decided to work with me. Within a few months, she no longer had to take time off work during her period, and a few months later she was even able to exercise during her period."

"“Inflammation down Bloating down Mental clarity My head feels clear, I feel like I’ve got life in my walk again No negative self destructive thoughts Dandruff gone Hair has stopped falling out Energy is creeping back up Fire in my belly feels rampant Holding my head high again I don’t measure or track my food either, and ya girl eats, a lot My cycle was 40–45 days apart with awful PMS symptoms. Sore boobs, bloating, acne, intense cravings, extremely heavy In today’s photo I’m on my period, I’ve experienced no symptoms at all, light flow, I was shocked I came on tbh, and it was 24days between I’m sure there is more that’s happened over the last 4–5 weeks.”"

"Business has accelerated from starting from scratch in May. Looking to scale more now I have worked through over 60% of the education and my broad ability to help clients has highly improved. 2 biggest wins with clients is a client who has severe endo and weightloss issues is almost symptom free and down over 10kg. Another client had nerve issues around the eye and is at risk of going blind, she has check ups every 3 months and they were astounded by what they were seeing, said she’s not at risk of going blind anymore, only thing that changed was diet and supplements."

"Finally got to the point in my life that I am able to increase my income without giving up my time. This is easily the best work life balance that I have had in my entire 15+ years in this industry! Seeing my wife and kids the most, coming home the earliest, not working weekends and we are at the same consistent income as our highest ever months (pre covid) — and without me working 12–14 hour days to do so."

What does an Integrative Nutritional Therapist do?
Plus icon, svg, dark

An Integrative Nutritional Therapist utilises the latest evidence-based research to create an integrative approach to optimising each client’s health and wellbeing.

They design bio-individual nutrition plans, personalise supplementation where appropriate, and interpret functional laboratory data, including blood work, to gain deeper insights, achieve better accuracy and tailor every intervention to the individual.

How is functional medicine different from conventional medicine?
Plus icon, svg, dark

Conventional medicine often waits until a disease is clearly present before intervention begins. Treatment is focused on managing or suppressing a diagnosed condition.

Functional medicine looks upstream. It assesses the early drivers of dysfunction and works to prevent disease from developing in the first place, or restore balance in the body. It uses a whole-systems view of the body, then applies personalised, preventative nutrition and lifestyle interventions to support long-term health rather than only reacting once things have gone wrong.

What will be my scope of practice after completing this certification?

  • Utilise functional blood work from a wellness perspective to guide your reasoning and recommendations
