Formula Used
This calculator uses a weighted screening model. It combines symptom intensity, diet frequency, sunlight exposure, and lifestyle modifiers. The result is normalized to a 0 to 100 score for each vitamin.
Risk Score = ((Symptom Weight + Intake Penalty + Lifestyle Modifier) / Maximum Points) × 100
Symptoms
Symptoms such as fatigue, bone pain, bruising, numbness, dry eyes, mouth sores, and poor night vision receive vitamin-specific weight.
Intake Penalty
Lower weekly intake of fish, dairy, eggs, citrus, legumes, or greens increases the related vitamin risk score.
Lifestyle Modifier
Smoking, alcohol use, pregnancy, digestive issues, low sunlight, and age can raise selected screening scores.

FAQs
1. What does this calculator measure?
It estimates the likelihood of common vitamin shortfalls using symptoms, food frequency, sunlight exposure, digestive concerns, and lifestyle inputs. It is a screening aid only.
2. Does a high score confirm a deficiency?
No. A high score only signals that your pattern looks more consistent with a possible deficiency. Diagnosis requires medical history, examination, and appropriate laboratory testing.
3. Why does diet pattern matter?
Some eating patterns provide fewer natural sources of certain nutrients. For example, strict vegan diets may need more attention to B12 and sometimes vitamin D intake.
4. Why is sunlight included?
Sunlight exposure affects vitamin D production. Lower weekly exposure can raise the vitamin D screening score, especially when symptoms and food intake point the same way.
5. Why are digestive issues weighted?
Digestive problems can reduce absorption of several nutrients. That means a person may still score higher even when food intake looks reasonable on paper.
6. Can I use this for pregnancy?
It can highlight folate-related screening risk, but pregnancy nutrition should always be reviewed with a qualified clinician because nutrient needs and safety decisions are individualized.
7. Which vitamins are included here?
This version screens vitamin D, vitamin B12, vitamin C, vitamin A, folate, and vitamin K using weighted symptom and intake patterns.
8. When should I seek medical help?
Seek medical advice for severe fatigue, numbness, bleeding, persistent mouth sores, major vision changes, pregnancy concerns, or symptoms that continue despite improving diet.
