THE THINKING BEHIND CELLR
Know why a module appears, what your score measures and where the limits are.
The initial questionnaire takes about 90 seconds. It asks about eligibility, your goals, day-to-day priorities, four simple wellbeing ratings and your routine. You can select several answers wherever more than one applies. It does not ask for diagnoses or a medication history.
All 12 modules are part of the collection. Your sex and conception plans determine which life-stage modules can appear. Pregnancy or uncertain pregnancy status excludes Foundation and every CELLR module. Several modules can have the same relevance: the questionnaire never forces one winner or adds a product automatically.
| Your answer | Contribution to the relevant module |
|---|---|
| A goal you select | +60 points for each selected goal, equally |
| A day-to-day area you select | +25 points |
| A relevant routine or lifestyle priority | +20 points; menopause relevance contributes +60 |
| Rest, energy, focus or movement comfort, rated 0–10 | 2 × (10 − your rating) for Sleep, Recovery, Cognition or Bone & Joint respectively; 0–20 points |
| Planning to conceive | +75 points for the appropriate fertility module |
Contributions are added and capped at 100. Scores of 60–100 are strongest matches; 25–59 are also worth considering; 0–24 are lower priority for now. Each result shows the answers behind it. Equal scores remain equal. Foundation is the common base and is not ranked against the modules.
This is a transparent preference-matching model, not a validated clinical tool, a probability of benefit or a measure of medical need. Choosing multiple modules remains your decision.
My CELLR brings your questionnaire and wearable readings together in a wellbeing tracking index. The latest rest, energy, focus and movement-comfort ratings are averaged and converted to 0–100. This questionnaire component expires after 30 days.
The wearable component uses your average sleep and steps across the past 7 days, compared with your own targets and capped at 100. Each metric needs at least 3 separate days of readings. If both metrics qualify, their goal-attainment scores are averaged. Duplicate dates use the last added value for each metric.
When both questionnaire and wearable components exist, their weights are 60% and 40%. Otherwise only the available component is shown. Missing data is not zero. The score identifies its coverage, and changing inputs or targets changes comparability.
This is not a validated clinical health score, biological age or evidence that a supplement caused a change. Heart rate, HRV, biometrics, lab results and supplement streaks remain separate.
Targeted follow-ups explore your chosen areas in more depth: focus, frequency, effect on daily life and personal importance. Their priority groups are separate from the initial matching scores. Equally important goals stay together. Preconception and preventive questions do not create disease-risk or fertility scores.
Some targeted follow-ups include a complete RAND 36 scale, with original wording, recall periods and response options. These selected scales are reported separately; they are not the full RAND 36 survey. Proprietary CELLR questions are clearly identified and are not presented as validated specialist instruments.
The complete four-item core records general health and physical, mental and activity-limited days over the past 30 days. The original skip rule is preserved. An optional five-item symptoms module is reported as separate item responses.
No combined nine-item clinical score is invented. Unanswered items remain missing. Healthy days are estimated by subtracting the capped sum of physical and mental unhealthy days from 30.
CDC items & modules ↗Scoring & public-domain status ↗All 36 original items are available, producing eight separate scale scores. Higher scores reflect more favourable reported health. Missing items are omitted from each scale’s average, with response coverage shown.
The health-change item stays separate. No overall RAND score or treatment-effect claim is produced.

The table describes relevant assessment instruments, not additional active forms or product endorsements. Full specialist forms require their own permissions and appropriate use. The initial quiz does not inherit their validation.
| Area | Relevant specialist instrument | Context |
|---|---|---|
| Gut Health | Gastrointestinal Symptom Rating Scale (GSRS), 15 items | Digestive focus, symptom frequency and impact; separate wellbeing assessments |
| Cognition | PROMIS Cognitive Function 8a, 8 items | Cognitive focus, frequency and everyday impact; no cognitive diagnosis |
| Recovery | PROMIS Fatigue 8a, 8 items | Energy/fatigue and physical function |
| Longevity | RAND 36-Item Health Survey 1.0, 36 items | General health and function; no biological-age score |
| Sleep | PROMIS Sleep Disturbance 8a, 8 items | Sleep-specific focus, frequency and daytime impact |
| Metabolic | RAND 36 general health; objective measures with clinical interpretation | Nutrition and movement priorities; no metabolic-risk score |
| Cardiovascular | RAND 36 physical function; clinician-interpreted blood pressure and lipids | Physical function; no cardiovascular-risk calculation |
| Bone & Joint | Musculoskeletal Health Questionnaire (MSK-HQ), 14 items | RAND 36 physical function and pain |
| Skin, Hair & Nails | Dermatology Life Quality Index only where clinically appropriate; no combined hair/nail score | General wellbeing; no cosmetic-outcome score |
| Menopause | Menopause Rating Scale (MRS), 11 items | General wellbeing; stage chosen by you |
| Female Fertility | FertiQoL only for the population and use it was validated for; preconception review separately | General wellbeing; no fertility score |
| Male Fertility | FertiQoL only for the population and use it was validated for; semen analysis via a clinician | General wellbeing; no fertility score |
Editable weekly meal ideas and activity plans are general lifestyle tools. They are not therapeutic diets or rehabilitation plans. Adapt them to your needs and check ingredients for allergies.
Manual readings and structured CSV imports work now. Automatic WHOOP and Oura sync requires provider authorisation; Apple Health and Health Connect require a compatible mobile app. Direct connections are not active. Lab results keep their original units and are not automatically interpreted.
Daily check-ins record what you say you have taken. Streaks measure consistency, separately from wellbeing. Repeat baskets restore your chosen routine for review; they do not place an order.
A questionnaire cannot confirm ingredient suitability, identify interactions or establish a need for supplementation. It does not replace qualified advice about persistent or worsening symptoms. CELLR does not claim here to treat disease, reverse ageing or improve lifespan.
All 12 modules can be explored and eligible modules selected. The basket shows prices and billing schedules, but payment, charging and fulfilment are not connected.
