Is this calculator a substitute for medical advice?

No. This calculator provides estimates based on general formulas. Always consult a qualified healthcare professional for medical decisions and personalized health advice.

How accurate are health calculators?

Health calculators use clinically validated formulas (like Mifflin-St Jeor for BMR). They provide reliable estimates but individual results may vary based on genetics, health conditions, and lifestyle.

Are the health benchmarks applicable to Indians?

Where applicable, we use Asian-specific health benchmarks. For example, our BMI calculator uses both WHO and Asian classification cutoffs, which are more relevant for South Asians.

Is my health data stored anywhere?

No. All health calculations run entirely in your browser. We do not store, transmit, or track any health information you enter.

Can I track my health metrics over time?

You can bookmark your results or save them as screenshots. The calculator provides instant results each time you use it.

Vitamin & Mineral Calculator

Q: Which vitamins are most commonly deficient in India?

Vitamin D (70–80% prevalence), Vitamin B12 (especially vegetarians), Iron (56% women are anemic), and Folic acid. Get Vitamin D from 20 minutes of midday sun, B12 from dairy or supplements if vegetarian.

Q: Should I take a multivitamin supplement?

Not if you eat a balanced diet with variety. Targeted supplementation of Vitamin D (1,000–2,000 IU/day for Indians), B12 (for vegetarians), and Iron (for women with heavy periods) is more effective than multivitamins.

Check your daily vitamin and mineral requirements by age and gender. See recommended dietary allowances (RDA) for essential micronutrients.

How Vitamin & Mineral Calculator is Calculated

This calculator uses the formula: Score = Sun Exposure Base × Skin Tone Multiplier × Age Multiplier. Where Optimal Vitamin D: 40–60 ng/mL ; Deficient: <20 ng/mL ; Insufficient: 20–30 ng/mL. Estimation only. Darker skin produces less vitamin D. Blood test (25-OH) is the gold standard. All calculations run entirely in your browser — no data is transmitted to any server.
