Question 1 of 250%
About You
What is your biological sex?
Influences reference daily intakes for iron, calcium, and several hormonal factors.
About You
What is your age group?
Nutrient needs shift significantly across life stages — B12, calcium, and D3 requirements increase with age.
About You
Where do you live?
Latitude directly affects UVB availability and therefore vitamin D synthesis. UK soils are also selenium-poor compared to North America.
Lifestyle
How much direct sunlight do you typically get each day?
Vitamin D3 synthesis requires direct UVB skin exposure. Glass, sunscreen, and cloud cover significantly reduce synthesis.
Lifestyle
What is your skin tone?
Melanin reduces UVB penetration. Darker skin tones require significantly more sun exposure to produce the same amount of vitamin D.
Diet
Which best describes your diet?
Dietary patterns create predictable nutrient gaps — even well-planned diets have known risk areas.
Diet
How often do you eat red meat or organ meats?
Red meat and organ meats are among the most bioavailable sources of iron, zinc, B12, and CoQ10.
Diet
How much dairy do you consume?
Dairy is the primary source of calcium and iodine for many people, especially in the UK.
Diet
How would you describe your vegetable and fruit intake?
Variety and quantity of plant foods significantly affects folate, vitamin C, magnesium, and potassium status.
Diet
How often do you eat processed or ultra-processed foods?
Ultra-processed diets are consistently associated with lower micronutrient density and higher inflammation.
Energy and Fatigue
Which of these do you experience regularly?
Regularly means at least 3 times per week over the past month, not explained by poor sleep alone.

Musculoskeletal Symptoms
Do you experience any of the following?
Muscle and bone symptoms are among the most specific nutrient deficiency signals in clinical literature.
Select all that apply
Mood and Mental Health
Have you noticed any of these in the past month?
Many mood symptoms have well-established nutritional correlates documented in clinical research.

Skin, Hair, and Eyes
Which of these apply to you?
Skin and hair changes are often among the earliest visible signals of nutrient depletion.

Digestive Health
Do you have any ongoing digestive conditions?
Gut health directly affects nutrient absorption. A healthy diet cannot compensate for impaired intestinal absorption.
Digestive Health
Have you taken antibiotics in the past 6 months?
Antibiotics disrupt the gut microbiome, reducing synthesis of vitamin K2, B vitamins, and short-chain fatty acids that support mineral absorption.
Activity Level
How active are you on a typical week?
Training intensity increases requirements for magnesium, electrolytes, B vitamins, and iron through sweat loss and metabolic demand.
Lifestyle
How much alcohol do you typically drink?
Alcohol impairs absorption and increases excretion of magnesium, zinc, B vitamins (especially B1 and folate), and vitamin D.
Lifestyle
Do you smoke, or have you smoked in the past 5 years?
Smoking significantly increases oxidative stress and depletes vitamin C (by up to 40%), vitamin E, folate, and zinc.
Lifestyle
How would you describe your sleep over the past month?
Poor sleep is both a symptom and a driver of deficiency — magnesium, vitamin D, and zinc all affect sleep quality.
Medications
Are you currently taking any of the following?
Many commonly prescribed medications deplete specific nutrients as a documented pharmacological side effect.

Health History
Do you have a diagnosed thyroid condition?
Thyroid disorders create bidirectional relationships with iodine, selenium, zinc, vitamin D, and iron — deficiency can worsen thyroid function and vice versa.
Health History
Have you had any significant illness, surgery, or prolonged infection in the past year?
Major illness and surgery dramatically increase requirements for vitamin C, zinc, protein, and iron during recovery.
Stress and Recovery
How would you describe your stress levels over the past 3 months?
Chronic stress accelerates depletion of magnesium, vitamin C, B vitamins, and zinc through elevated cortisol and urinary excretion.
Supplement History
Are you currently taking any supplements?
Knowing your baseline helps identify remaining gaps and potential interactions or redundancies in your current routine.

Important: These results are generated algorithmically from population-level research (NIH, EFSA, PubMed). They indicate statistical likelihood of deficiency based on your answers — not a diagnosis. Actual deficiency can only be confirmed through clinical blood tests. Share these results with your GP or registered dietitian before changing your supplement routine.
