Functional Nutritional Therapist, Nutrigenetic Counsellor and the Founder of EYZHN (ev zin).
Hello! I'm Tamara.
I specialise in uncovering and addressing the root causes of health issues, using the latest insights in nutritional science and genomics. My goal is to help you manage, reverse, or achieve remission of chronic conditions, prevent disease, and optimise your health.
Inspired by the Ancient Greek philosophy of "ευ ζην" (ev zin)—the pursuit of a balanced and fulfilling life—I integrate Functional Medicine principles to empower you with the knowledge and tools to support your body’s natural healing ability.
While my primary focus is supporting women over 30 with gastrointestinal, energy, and thyroid issues, I also work with clients to navigate autoimmune disorders, hormonal health, and challenges related to weight and overall well-being.
If you're ready to begin your journey toward better health, I invite you to schedule a FREE strategy call. I offer virtual consultations worldwide from Hong Kong (GMT +8).
Qualifications & Accreditations
I graduated with distinctions from the Institute for Optimum Nutrition (ION) in London, accredited by the Nutritional Therapy Education Commission (NTEC). I am a Professional Member of the British Association for Nutrition and Lifestyle Medicine (BANT) and hold Nutrigenetic Counsellor (NgC) Register status, adhering to rigorous standards and ethical practices in nutrigenomics for precision nutrition. To ensure I remain at the forefront of these evolving fields, I dedicate a minimum of 30 hours annually to ongoing professional development. Additionally, I hold a BBA and an MSc in General Management, with honours, from Bocconi University in Milan.
Services
Nutritional Therapy embodies the principles of Functional Medicine, leveraging nutritional science and lifestyle medicine to enhance health, prevent diseases, and provide individualised care. It acknowledges that health isn’t an on-off switch but exists on a spectrum, with chronic conditions often developing from the gradual deterioration of various body systems influenced by diet, environment, lifestyle, psychology, biochemistry, and genetics. The goal is to identify these underlying causes and restore function by bolstering the body's innate healing mechanisms.

Irritable Bowel Disease (IBD)
Irritable Bowel Syndrome (IBS)

Client testimonials
Services
Nutritional Genomics encompasses both nutrigenomics and nutrigenetics, exploring how nutrients and the environment influence gene expression, and how gene variations affect nutrient metabolism. Our genes do not dictate our health but reveal our risk factors. This insight enables us to optimise genetic expression with uniquely tailored nutrition and lifestyle adjustments for disease prevention, longevity, and enhanced healthspan.
DNA Core Package

NUTRITIONAL GENOMICS
Frequently asked questions
-
SNPs, or single nucleotide polymorphisms, are variations in the genetic code at specific positions in the genome. Within the 3 billion base pairs of human DNA, SNPs arise approximately once every 300 nucleotides, acting as biological indicators that shape individual traits, and affect gene expression and metabolic functions critical for cellular health. These variations also impact how you respond to environmental factors like diet, lifestyle, supplements, and exercise, contributing to your uniqueness.
-
Genetic testing can help you understand how your genes and surroundings work together to shape your health. While your genes provide the blueprint, epigenetics—how genes are read and activated—determines their expression. By examining specific genetic variations that can collectively impact disease risks, this testing allows early identification of potential health issues. Taking action early helps tailor personalised strategies for better health, improving outcomes, and enhancing the quality of life, especially for those susceptible to certain diseases.
-
I currently collaborate with genetic testing companies that focus on a limited number (35-70) of extensively researched SNPs per report. Every SNP undergoes rigorous validation, often with 'double' or 'triple pass' validation, ensuring each SNP is confirmed at least 2 to 3 times. This meticulous precision distinguishes these companies from larger-scale genetic testing firms that handle vast data points in the thousands or millions, where even a 0.01% error rate can result in numerous discrepancies.

All samples are destroyed after 3 months, ensuring strict confidentiality. Your genetic data is solely used for the tests and never shared or sold to third parties.
We must look at the health of the roots to understand why the leaves look wilted.

Did your blood tests come back "normal," but you still feel unwell? This could be because standard blood tests often compare your results to broad average ranges, which can often miss early signs of imbalance. Functional Medicine uses more precise, optimal ranges that can help detect subtle issues before they escalate. For example, instead of waiting for iron deficiency to turn into anaemia or for insulin resistance to progress to diabetes, you can intervene early to prevent these conditions from worsening.
By identifying patterns in your blood work, Functional Blood Chemistry Analysis (FBCA) can reveal signs of dysfunction—even when your results fall within 'normal' lab ranges—allowing for a proactive approach to address them early.

Frequently asked questions
-
Conventional blood reference ranges are based on averages from the general population, which includes individuals with varying degrees of health issues. Laboratories define "normal" as the values found in roughly 95% of their sample population, with the upper and lower 2.5% considered abnormal. However, these are statistical averages, not true indicators of optimal health. Optimal ranges, on the other hand, are narrower and based solely on data from healthy individuals. This allows practitioners to identify potential imbalances or issues early—long before they develop into more serious conditions.
-
Yes, you can! You can book a single 60-minute consultation here. If you're a new client, please schedule a complimentary 30-minute call or contact me via WhatsApp first, to ensure we’re a good fit before proceeding.
-
The FBCA report is ideal for anyone seeking deeper insights into their health, especially:
Individuals aiming to optimise their well-being by identifying and addressing imbalances before they become serious.
Those experiencing unexplained symptoms or feeling "off" despite normal lab results.
People managing chronic conditions who want closer monitoring of their health.
Anyone looking for a personalised approach to nutrition, lifestyle, and supplementation based on their unique blood markers.
Whether you're focused on preventing future health issues or improving an existing condition, the FBCA report offers valuable information to help guide your wellness priorities.
-
Yes, your blood test results should be no older than 3 months to ensure the most accurate and relevant analysis. If you don’t have recent test results, I can provide guidance on which biomarkers to include before you get tested.
-
Absolutely! You can upload the results from any recent blood tests conducted by your doctor or lab, provided they are no older than 3 months. File types supported include:
documents
PDFs
images
spreadsheets.
-
If you've purchased the FBCA Report Only, your report will be emailed to you within 2 working days of receiving your blood test results. For those who have purchased the FBCA Report + Consultation, you’ll receive your report and health plan within 2 working days of the consultation.
