01 — Who we are

A science-based approach to prevention

Chigra Bio is a start-up founded by university professors of clinical pharmacy and medical biochemistry and developed in collaboration with practising clinicians, with the aim of providing personalised preventive services that preserve and improve health.

We combine the measurement of biomarker concentrations and, where justified, additional epigenetic testing with multidisciplinary interpretation, and translate the findings into personalised supplementation and nutrition protocols that we monitor, reassess and adjust over time.

Supplementation only when it is clearly indicated. Each recommendation is held to the standard we apply to pharmacotherapy — a defined indication, supporting evidence, an individual dose and duration, a check for interactions and a planned reassessment. When supplementation is not needed, we say so.

02 — The case for prevention

Why prevention, and why now

43M

deaths from non-communicable diseases worldwide in 2021

75%

of all deaths not related to the pandemic

18M

of those deaths occurred before the age of 70

A substantial share of these deaths is linked to modifiable risk factors such as poor diet, physical inactivity, smoking and harmful alcohol use, whose negative effects on health develop gradually, over years. Medicine is exceptionally good at treating established disease, yet it has far fewer structured tools for the long interval before signs and symptoms of disease appear. That interval is where structured, individualised prevention adds value.

Built on P4 medicine

P1

Predictive

Identify risk as early as the data allow.

P2

Preventive

Act on modifiable factors before they disturb the body's balance.

P3

Personalised

Fit every recommendation to the individual's data and context.

P4

Participatory

Engage the client in understanding results, recommendations and follow-up.

03 — Our clinical standard

Supplementation, held to a therapeutic standard

Supplements are often taken on one's own initiative, without a prior assessment of whether their use is justified, the appropriate dose, the duration of supplementation or possible interactions with medicines. That is why, before recommending supplementation, our team works through seven key questions.

  1. 01Do you really need this supplement?
  2. 02Why this supplement, and in which form?
  3. 03Is the dose tailored to you?
  4. 04How long should you take it?
  5. 05Is it safe to combine with the medicines and other supplements you take?
  6. 06How do we know it is really helping you?
  7. 07When should the protocol change or stop?

Four foundations of healthy living

Sleep
Physical activity
Nutrition
Stress & social connection

Irreplaceable foundations of good health. Every protocol we write starts from these four and builds on them.

Chigra Bio does not diagnose, treat or replace medical care, and does not alter prescribed therapy. Clinically significant findings are referred back to the treating physician or to the appropriate specialist.

Programmes

Two programmes, one standard

A biomarker-led or an epigenetic assessment — always with expert interpretation, a personalised protocol and follow-up.

Programme 01

Chigra Panel

A biomarker-led assessment with multidisciplinary interpretation, a personalised protocol and one month of structured follow-up.

Programme 01 · Measurement
33parameters,
one coherent picture

The panel covers carefully selected biochemical and haematological markers that give insight into metabolic and hormonal health, the function of key organs and the overall state of the body, making it possible to recognise potential deviations and create individually tailored recommendations. Recent results from any laboratory, no older than one month, are accepted.

Laboratory of choice

The full list of analyses

All analyses on our list are required. Results must be no older than one month.

04 — Epigenetics in brief

The measurable layer between genes and lifestyle

The DNA sequence remains largely unchanged throughout life. Epigenetic marks, above all DNA methylation at CpG sites, help regulate gene activity and change with age, but also under the influence of lifestyle and environmental factors such as diet, sleep, physical activity, stress and smoking.

Based on DNA methylation patterns, validated algorithms known as epigenetic clocks can estimate biological age from a small blood sample, and some can also estimate the current pace of biological ageing.

Genetic testing

What was inherited

A static result: essentially the same at 30 as at 60.

Epigenetic testing

How one is living

A dynamic result that responds to change and supports retesting.

Programme 02 · The pathway

A closed loop

A single epigenetic result offers a current insight into biological ageing. Its real value comes from following change over time. Repeating the measurement after a period of targeted intervention lets us assess whether changes in lifestyle and supplementation are reflected in markers of biological ageing.

Capillary blood sample and epigenetic analysis.

02

Interpret

Multidisciplinary review in clinical context.

04

Retest

Typically at six months; the protocol is adjusted.

08 — What your patient receives

The protocol – clear to the client, useful to the physician

Every protocol is clearly structured, so that the client understands the recommendations and their physician can review them and assess how they fit with existing therapy.

Supplement protocol

  • Substance and its form
  • Dose and regimen — how much, when, how
  • Duration
  • Rationale for this individual
  • Precautions and interactions with current medicines
  • Date of planned reassessment

Nutrition plan

  • Dietary priorities derived from the findings
  • Practical guidance for everyday meals
  • Food-first sources of key nutrients
  • Adjustments for medicines and conditions

When supplementation is not indicated

We say so clearly and suggest next steps. Our programmes are built on expert assessment, interpretation of results and individual recommendations; supplementation is never assumed in advance and is recommended only when justified.

Shared with the treating physician

The protocol is sent to the client in writing. With the client's consent, we send it directly to the referring clinician.
