Ms Tamara Agusta


EYZHN · Nutrition & Genomics
Happy Valley, Hong Kong S.A.R.

About the practitioner
Tamara Agusta is a Nutritional Therapy Practitioner, Nutrigenetic Counsellor, and functional bloodwork specialist. Her practice is built on one idea: most blood tests come back "in range," but a range only shows where you are not where you're heading. Markers drift for years before they cross a line; Tamara reads that trajectory, catching imbalances early and turning complex results into a plan you'll actually follow. Her practice, EYZHN (ev zin), takes its name from the Ancient Greek for "living well" for the Greeks, the good life was a practice, not a body of knowledge, and closing that gap between knowing and doing is where Tamara works. She brings 18 years of international corporate leadership across Milan, Shanghai, and Hong Kong, and applies the same systems thinking to biology that she once applied to businesses. In 2026 she launched SnaqBreak, a science-backed micro-workout app for sedentary workers, built on the same evidence-first principles as her clinical work. Based in Hong Kong, working with clients worldwide. Her flagship service, the Functional Bloodwork Audit, applies optimal ranges and functional analysis to clients' existing lab results, delivered as a written report with a prioritised 3-step action plan.
