Don't recognize yourself anymore? 

I help women in their 40s(+) feel more energized, lose weight, sleep well and end the anxiety, irritability and depression!

Hi, I'm Marieke! 

I’m a functional nutritionist  and I help women rebuild energy, calm their nervous system, and support hormones through a root-cause approach to stress, digestion, inflammation, and metabolic health.

For years, I was the woman doing everything “right” while my body kept reacting anyway.​

My own journey through gut dysfunction, hormone imbalance, chronic stress, and repeated mold exposure led me to develop the S.E.N.S.E. Method - a structured approach designed to help women stabilise reactive systems, uncover hidden stressors, and restore balance without overwhelming the body.

Today, I combine functional nutrition, nervous system support, gut healing, detoxification, and hormone education to help women who feel like a stranger in their own body finally understand what’s driving their symptoms - and what to do next.

Because when your body reacts to everything, the answer isn’t to push harder.

It’s to understand what your system has been trying to tell you all along.

Testimonials

Teresa

Before working together, I struggled with uneven energy and confusion about what foods were truly healthy for me. After trying strict diets, functional tests, and even psychotherapy, nothing made a real difference - until now. Working through the protocol has brought steady energy, no more cravings, and greatly reduced bloating and gas.

Marieke helped me clean my diet before conception and during the pregnancy when I was flagged as a risk for gestational diabetes. I managed to control both through diet and could avoid being put on insulin.

I had the chance to know Marieke as a former colleague and understood already by then her untamed passion for healing the body in a natural and holistic way. When I decided to start a check-up with Marieke, I was rapidly impressed by her level of professionalism and the very unique, flexible and tailored approach, which rapidly provided lasting results. I can only highly recommend Marieke for anyone who wants to restore his health in a natural way, by using food and natural remedies.

“I was having migraines several times a month, tired every day by the afternoon, often shakey, I had constantly high anxiety and terrible digestive issues.

Marieke has honestly transformed my life. I know people say that and it sounds phoney, but in this case I mean it. When I have a migraine I can be in bed and useless for days. But since working through the healing protocol I haven’t suffered a single one. For me, that’s incredible, and a massive life upgrade. And since working with Marieke, constipation is no longer an issue for me - which I never thought I’d achieve! I am no longer shaky and tired in the afternoons and my anxiety has come right down. I’m much more aware now of what I put in to my body and how it affects me afterwards, meaning I have naturally become a habitually healthier eater, which feels way more feasible to keep up than a dieting fad."
