When You’re Doing Your Best but Still Don’t Feel Like Yourself
Perhaps your energy crashes halfway through the day. Your digestion has become unpredictable, your weight or appetite has changed, or symptoms that once felt manageable have become harder to ignore.
For many women, several things are happening at once. Perimenopause, stress, sleep, digestive health, nutritional deficiencies, medication and everyday eating habits can all affect how you feel.
You don’t need another restrictive diet or a generic list of foods to avoid. You need time to look at your health properly and work out which changes are relevant to you.
What Can Nutritional Therapy Help You Explore?
Nutritional therapy looks at your symptoms, health history, eating patterns, lifestyle and goals together. The support is personalised, and any testing or supplements are considered only when they are appropriate.
Energy, Brain Fog and Burnout
If you regularly feel exhausted, unfocused or dependent on caffeine and sugar to get through the day, we can examine your meal pattern, nutrient intake, sleep, stress and relevant health factors.
For bloating, constipation, changes in bowel habits or ongoing digestive discomfort, we look beyond a generic elimination diet and identify practical next steps. Medical assessment is recommended where symptoms require it.
Digestion and Gut Health
Sustainable Weight and Appetite Support
If restrictive diets have led to cravings, food noise or repeated weight regain, I offer a more sustainable approach based on nourishment, realistic habits and individual support.
Nutrition cannot prevent hormonal change, but it can support energy, digestion, muscle, cardiovascular health and overall wellbeing through perimenopause and menopause.

Nutrition Advice Is Easy to Find. Knowing What Applies to You Is Harder.
There is no shortage of information about protein, supplements, gut health, blood sugar and hormones. The difficult part is knowing what matters for your body, your health and your daily life.
My role is to help you make sense of that information and turn it into a realistic plan. We begin with a detailed assessment, agree on clear priorities and make changes in manageable stages.
Depending on your needs, support may include:
Reviewing your current diet, symptoms and health history
Creating a personalised nutrition and lifestyle plan
Helping you establish a realistic meal structure
Reviewing existing blood-test results
Considering functional testing where there is a clear reason
Recommending supplements only when appropriate
Providing structured follow-up and adjustments
Nutritional therapy works alongside appropriate medical care and does not replace diagnosis or treatment from your doctor.
Choose the Level of Support You Need
Some people need an individual assessment and personalised plan. Others already understand the basics and need ongoing education, structure and accountability.
Personalised One-to-One Nutritional Therapy
For ongoing symptoms, individual assessment, tailored nutrition advice or functional testing.
Choose from structured six-week, three-month and six-month programmes, with the level of support matched to your needs.
Thrive Together
Monthly online nutrition coaching and accountability for women who want help turning healthy intentions into consistent everyday habits.
Thrive includes a monthly nutrition masterclass, small-group coaching, seasonal meal ideas and practical habit support.
Employee Wellbeing Support
Practical talks, workshops and employee wellbeing support for organisations.
A Clear Starting Point
1. Book a Free Call
Tell me what has been happening, what you have already tried and what you would like to change.
2. Choose the Right Support
I’ll explain whether one-to-one nutritional therapy is appropriate and which programme best fits your needs. There is no obligation to continue.
3. Build a Realistic Plan
If we decide to work together, we’ll turn your priorities into practical changes and review what is working as you progress.
Qualified Guidance with a Practical Approach
I’m Sanna Sumner, a qualified Nutritional Therapist based in Amsterdam.
I hold a Bachelor of Science in Nutritional Therapy from the University of West London and have more than 10 years’ experience supporting clients with nutrition and lifestyle change. I am also a member of BANT, the British Association for Nutrition and Lifestyle Medicine.
My additional training includes functional blood analysis, hormonal testing, nutrigenomics, thyroid health, obesity and disordered eating.
I combine scientific evidence with a practical understanding of busy lives. My aim is not to give you a perfect diet to follow. It is to help you understand what may be affecting your health and make changes that are appropriate, manageable and sustainable.
Consultations are held online, so I work with clients in Amsterdam, across the Netherlands and internationally.
“I would describe it as educating and life-changing.
I feel as though there is still a lot to learn about food but this has really helped me listen more to my body.”
— Lisa, 43

Common Questions
Do you only work with clients in Amsterdam?
No. I am based in Amsterdam, but consultations are held online, so I work with clients across the Netherlands and internationally.
How do I know which programme is right for me?
Book a free 20-minute discovery call and tell me what you would like help with. I’ll explain which option appears most appropriate and whether my approach is a good fit.
Do I need test results before we begin?
No. We start with your symptoms, history, diet and goals. Existing medical results can be reviewed, and further testing is considered only when there is a clear reason.
Can nutritional therapy support me if I take medication?
Often, yes. Nutritional therapy can work alongside medical treatment, but it does not replace your doctor or prescribing clinician. Any relevant medication will be considered when making recommendations.
What is the difference between one-to-one support and Thrive Together?
One-to-one programmes provide an individual assessment and personalised plan, with testing considered where appropriate. Thrive Together provides monthly group education, coaching and accountability. It does not include individual clinical assessment or functional testing.
Is the discovery call a consultation?
No. It is a free 20-minute conversation to understand what you need, answer initial questions and decide whether working together makes sense. Personalised health recommendations are provided only after a full assessment.
Not Sure Where to Begin?
