Start here

Q1 required

What name should we use for your report?

First name is fine. This is for your reference only.

Please enter a name.

What we will ask, and why

Start here. Your name, your age, and what you want the report to work on.
About you. Height, weight, and how you sleep, move and work.
Your health and medications. Conditions, prescriptions, anything you buy over the counter, and allergies. This is the section that decides what we can safely recommend.
What you take now. Supplements, any recent blood tests, alcohol and smoking.
What you eat. A short food check, so we only suggest what your diet does not already cover.

We sell nothing: no affiliates, no commission, no products of our own, so the recommendations follow the evidence and nothing else. Your answers stay on your device until you send them at the end, they are used only to build your report, and they are never shared.

Section 3 of 5

Your health and medications

Please read each question carefully: the safety checks we run, and the interactions we look for, depend on exactly what you tell us here. It is never for judgement, and it stays confidential.

Q10 required

Have you ever been diagnosed with any of the following?

Tick all that apply.

Metabolic & Cardiovascular

Type 1 diabetes Type 2 diabetes or pre-diabetes High blood pressure (hypertension) High cholesterol / dyslipidaemia Cardiovascular disease (heart disease, coronary artery disease, history of heart attack) Stroke or TIA (mini-stroke) Atrial fibrillation, atrial flutter, or other arrhythmia Metabolic syndrome Insulin resistance (non-diabetic) NAFLD / non-alcoholic fatty liver disease

Hormonal & Reproductive

PCOS (polycystic ovary syndrome) Hypothyroidism (underactive thyroid) Hyperthyroidism (overactive thyroid) Hashimoto's thyroiditis Endometriosis Fibroids

Autoimmune

Rheumatoid arthritis (RA) Lupus (SLE) Multiple sclerosis (MS) Psoriasis / psoriatic arthritis Crohn's disease or ulcerative colitis (IBD) Coeliac disease Other autoimmune condition

Respiratory

Asthma (diagnosed) COPD (chronic obstructive pulmonary disease)

Gut & Digestive

Irritable bowel syndrome (IBS) SIBO (small intestinal bacterial overgrowth) Acid reflux / GORD Liver disease (other than NAFLD)

Important: liver disease

Liver disease affects how the body processes many supplements, and some compounds are directly hepatotoxic at higher doses. Your report will apply dose-conservative recommendations for this profile, but the appropriate supplement plan depends heavily on the type and severity of your condition. Please review any recommendations with your hepatologist or gastroenterologist before use.

Kidney

Chronic kidney disease (CKD): any stage Recurrent kidney stones Single kidney Other kidney condition

Mental Health

Anxiety disorder (diagnosed) Depression (diagnosed) Bipolar disorder History of mania, hypomania or psychotic episode OCD PTSD Eating disorder (current or history of)

Neurological

ADHD (diagnosed or suspected) Autism Spectrum Disorder / ASD (diagnosed or suspected) Migraine Epilepsy / seizure disorder Parkinson's disease Dementia or Alzheimer's disease

Musculoskeletal

Osteoporosis or osteopenia Osteoarthritis Fibromyalgia Gout

Other

Anaemia (type if known) Haemochromatosis (iron overload) Bleeding disorder (e.g. haemophilia, von Willebrand disease, ITP) Thrombophilia / clotting disorder (e.g. Factor V Leiden, antiphospholipid syndrome) Macular degeneration Tinnitus Caffeine sensitivity / intolerance HIV / AIDS Organ transplant recipient None of the above

Important: antiretroviral interactions

Your report will be generated and may be useful as a general reference, but it does not account for the full range of interactions between supplements and antiretroviral therapy (ART). ART drug interactions are complex and class-specific. Before acting on any recommendation in your report, please review it with your HIV specialist or pharmacist.

Important: immunosuppressant interactions

Several commonly recommended supplements interact with immunosuppressant medications (including tacrolimus, ciclosporin, and mycophenolate). St. John's Wort in particular can reduce blood levels of these drugs sufficiently to trigger organ rejection. Your report will flag known interactions, but it cannot account for every individual protocol. Please review any recommendations with your transplant team before making changes to your supplement routine.

Please select at least one option.

Q9: IBS type

Do you know which type of IBS you have?

Different types respond to different compounds. This helps us tailor your recommendations.

IBS-C (mainly constipation) IBS-D (mainly diarrhoea) IBS-M (mixed: both constipation and diarrhoea) I'm not sure which type

Q10: CKD required

Which stage of chronic kidney disease have you been told you have?

This affects safe doses for several compounds including Vitamin D, Magnesium and Vitamin C. If you are not sure, say so below and we will use the more cautious doses.

Stage 1–2 (mild) Stage 3 (moderate) Stage 4–5 (severe) I don't know my stage

Please select an option. If you do not know your stage, choose the last option.

Q10: Eating disorder follow-up required

If you ticked an eating disorder above, please tell us where you are with it.

This affects whether and how we can responsibly produce a report for you. Your honest answer matters.

Currently in treatment (any active eating-disorder care: GP, dietitian, therapist, inpatient, day-patient) In recovery (treatment completed within the last 12 months) Recovered (no active treatment for 12+ months) Prefer not to say

Not the right fit during active treatment

A personalised supplement plan is not the right tool during active eating-disorder treatment. Recovery work is led by your treatment team and centres on food, not supplements: a list of capsules and powders can become its own preoccupation, and we would rather defer to the people who know you and your care plan.

If you would like support, BEAT (the UK eating-disorder charity) runs a free helpline at 0808 801 0677 and webchat at beateatingdisorders.org.uk. Your GP can also refer you back into treatment at any point.

Please select an option.

Q10a

Please add any useful detail about your diagnosis(es).

How long ago, whether it's currently managed, treatment status, or the specific type.

Q10b

Have you taken a course of antibiotics in the last 3 months?

Yes: completed within the last month Yes: completed 1–3 months ago No I'm not sure

Q11 required

Do you have a personal history of cancer?

No Yes: previous history, treatment completed Yes: currently receiving treatment Prefer not to say

Not suitable during active cancer treatment

During active treatment, supplement decisions need to be made together with your oncology team: many otherwise-helpful compounds can interfere with the mechanism of chemotherapy or radiotherapy, and the right answer depends on your specific regimen and current bloods. We would not feel comfortable producing a report that could undermine your treatment, so we cannot generate one for you right now. We hope to be able to help you again once you are past active treatment.

Please select an option.

Q12 required

Does any of the following apply to you right now?

I am currently pregnant I am currently breastfeeding I am trying to conceive (actively trying or plan to within the next 12 months) None of the above

Not suitable during pregnancy or breastfeeding

This report is not designed for use during pregnancy or breastfeeding. Supplementation during these periods carries specific risks that require oversight from your midwife, GP, or obstetrician, not a general-purpose report. Please speak to your healthcare provider for personalised guidance.

Please select an option.

Q12a

How would you describe your menstrual bleeding?

Heavy periods are a significant driver of iron deficiency. This shapes our recommendations.

Normal Heavy (changing every 1–3 hours, or passing clots) Very heavy (flooding or impacting daily life) Light or irregular No periods / post-menopause / hormonal contraception Prefer not to say

Q13 required

What is your current menopause status?

This significantly affects bone, cardiovascular, hormonal, mood, and sleep recommendations.

Are you currently taking any prescription medications?

Yes No

Please select an option.

Please list all your prescription medications by drug name and dose if known. Include inhalers, patches, injections, and contraceptives.

Please list your medications by name. The interaction checks in your report depend on knowing which medicines you take, not just the type.

Q16 required

Do you currently take any of the following types of medication?

A safety check for specific interactions. Please read each option carefully.

Antidepressant: SSRI (e.g. sertraline, fluoxetine, citalopram) Antidepressant: SNRI (e.g. venlafaxine, duloxetine) Antidepressant: MAOI (e.g. phenelzine, tranylcypromine) Mood stabiliser (e.g. lithium, lamotrigine, valproate) Antipsychotic (e.g. quetiapine, olanzapine, risperidone) Dementia or memory medication (e.g. donepezil, rivastigmine) Anticoagulant / blood thinner (e.g. warfarin, apixaban, rivaroxaban) Aspirin: prescribed daily Thyroid medication (e.g. levothyroxine, liothyronine) Metformin Other diabetes medication (e.g. SGLT2 inhibitors, GLP-1 agonists) Statin (e.g. atorvastatin, simvastatin, rosuvastatin) ACE inhibitor (e.g. lisinopril, ramipril, perindopril) ARB / angiotensin receptor blocker (e.g. losartan, candesartan) Diuretic / water tablet (e.g. furosemide, spironolactone) Beta blocker (e.g. bisoprolol, atenolol, propranolol) Oral contraceptive / hormonal contraception HRT (hormone replacement therapy) Immunosuppressant (e.g. methotrexate, azathioprine, adalimumab) Inhaled corticosteroid (e.g. beclometasone, fluticasone) Oral corticosteroid (e.g. prednisolone) PDE5 inhibitor (e.g. sildenafil, tadalafil) Antiepileptic / anticonvulsant (e.g. carbamazepine, phenytoin) PPI / acid reflux medication (e.g. omeprazole, lansoprazole) None of the above

Please select at least one option.

Do you currently get muscle aches, pain, tenderness or weakness that you think may be related to your cholesterol medication?

This is common and usually not serious. We ask because several supplements share a clearance pathway with statins, and we would rather know your starting point before suggesting any of them.

No Yes, mild or occasional Yes, ongoing or troublesome I'm not sure

Please choose one so we know your starting point.

Q16b required

Do you regularly take any of the following?

Include anything taken at least weekly, even if bought from a health food shop or online.
