Why Legacy Nutrition exists
Doing all the right things, and still feeling stuck
Legacy Nutrition started after years of working with women who looked like they were coping, but felt anything but.
Most had already cleaned up their diet, tried supplements, exercised and tried to manage stress. Many were told their blood tests were normal. The fatigue, bloating, cycle problems, anxiety, poor sleep and stubborn weight stayed.
The pattern was clear. It was rarely about effort. Their bodies were overloaded and stuck in survival mode, not in a state that allows repair.
I've been the tired, snappy mum too. I'll tell you straight what's going on, then make it doable around kids, work and real life.
How I work
Regulate first, then restore, then personalise
The order matters. A stressed nervous system slows digestion, disrupts hormones and makes blood sugar harder to control, so I start there. Each stage builds on the last, so progress feels steady instead of fragile.
Regulation
Calm the nervous system, steady blood sugar, improve sleep and lower the stress load.
Restoration
Rebuild digestion, gut health, nutrient status and immune balance, and bring inflammation down.
Recalibration
Personalise hormone, detox and genetic support once your body has the capacity to respond.
Who I work with
Women who are capable, busy and tired of guessing
- PMS, PMDD, PCOS, endometriosis and irregular cycles
- Perimenopause: 3am wake-ups, rage, weight gain and low energy
- Bloating, IBS, reflux, SIBO and food reactions
- Fertility and preconception care for you and your partner
- Fatigue and "normal" bloods when you don't feel normal
My job isn't to push your body harder. It's to help you understand what your symptoms are telling you, and rebuild trust in your body.
The meaning behind Legacy
Harakeke, and the health we pass on
Legacy Nutrition is symbolised by harakeke, the flax plant, which represents whānau in Māori tikanga. The rito, the central shoot, is the child. It's protected by the awhi rito, the parents, while the outer leaves are the tūpuna, the grandparents and ancestors.
The legacy we pass on is shaped not only by our genes, but by our health, habits and the way we show up. Like the unfolding leaves of the harakeke, there's always room for renewal.
Is the way you care for your health aligned with the legacy you want to pass on?
