What is it?

The questionnaire is based on the scientifically grounded KNEV method (Client-Based Nutritional Evaluation), which draws inspiration from the book Signs and Symptoms Analysis from a Functional Perspective by Dicken Weatherby. With one digital assessment, you collect in-depth information about your patient’s diet, lifestyle, and possible nutritional imbalances.

This method is widely used in integrative and functional health settings and helps professionals quickly gain relevant insights. Fully digital and without manual processing.

What does the questionnaire measure?

The questionnaire maps out your patient’s eating habits, supplement use, physical signals, and lifestyle patterns. Responses are automatically analyzed to identify potential nutritional imbalances - such as vitamin deficiencies, digestive issues, or oxidative stress.

You receive a clear, structured report to support your supplement advice or care plan.




Why trust this method?

The questionnaire is built on the well-established KNEV method, which originates from the reference work Signs and Symptoms Analysis from a Functional Perspective by Dicken Weatherby. This approach has been used for years by healthcare professionals across Europe and beyond.

Its interpretation is grounded in clinical experience and nutritional biochemistry, and is regularly updated to support professionals who want to work in an evidence-based and structured way.
