This is a screening tool based on documented symptom patterns and risk factors, not a diagnosis. It points you toward which blood tests are worth requesting — the only way to actually confirm a deficiency.
Which nutrient deficiency do you have? Over the past several guides, we’ve covered six of the most commonly missed nutrient deficiencies one at a time — B12, iron, zinc, magnesium, vitamin D, and protein. This finder brings them together, matching your actual symptom pattern and risk factors against all six at once, visualized on a radar chart, the way a doctor mentally cross-references a full history rather than checking one nutrient in isolation.
How This “Which Nutrient Deficiency Do You Have” Finder Works
Each symptom is weighted based on how strongly and specifically it’s associated with each of the six deficiencies in published clinical literature. The six risk-factor chips add further weight based on well-documented population-level risk — a vegetarian diet, for instance, genuinely raises B12, iron, and zinc risk independent of current symptoms.
When you click “Find My Match,” the tool totals your weighted score for each nutrient and converts it to a percentage of that nutrient’s maximum possible score, so a deficiency with fewer, more specific symptoms isn’t unfairly outscored by one with more symptoms and risk factors listed.
The confidence score reflects how much information you provided — a result based on 2 ticked boxes is inherently less reliable than one based on 12, and the tool says so directly rather than presenting every result with equal false certainty.
The radar chart plots all six percentages at once on a single visual, so you can see your overall pattern shape — a sharp single spike suggests one dominant match, while a wide, spread-out shape suggests several overlapping gaps worth testing together.
Why Symptoms Overlap So Much
Fatigue alone shows up in iron, B12, and magnesium deficiency. Hair thinning shows up in four of the six. This isn’t a flaw in the tool — it’s a genuine feature of how these nutrients work in the body.
Many of these six nutrients support overlapping systems: cellular energy production, immune function, and tissue repair all depend on multiple nutrients working together, not any single one in isolation. A shortfall in almost any of them can produce a similar-feeling fatigue or a similar-looking bout of hair thinning.
It’s also worth knowing that overlapping deficiencies aren’t a coincidence in many cases — a vegetarian diet, for instance, raises risk for B12, iron, and zinc simultaneously, since all three are more abundant and more easily absorbed from animal foods. Someone with several matching nutrients in their results isn’t necessarily wrong about any of them; they may genuinely have more than one gap at once.

What This Tool Can’t Do
It can’t account for medications, other health conditions, or lab-specific reference ranges, all of which can shift how a real result should be interpreted.
It also can’t diagnose anything — its entire purpose is to help you walk into a blood test with a clearer, more specific idea of what’s worth requesting, rather than guessing or requesting every test available.
Our Blood Report Decoder is the natural next step once you actually have test results in hand — it reads 20 markers together and flags real combination patterns, picking up exactly where a symptom-based finder like this one has to stop.
Your Privacy
Working out which nutrient deficiency do you have shouldn’t require handing over personal data. Every calculation happens directly in your browser. Nothing you select is sent to, logged, or stored on any server by Sehatsphere. The optional Save Profile feature stores your answers only on your own device’s browser storage.
The Short Version: Which Nutrient Deficiency Do You Have?
- Add your sex, age, and any relevant risk factors for a more accurate match.
- Tick whatever symptoms apply across all five categories.
- Results show a radar chart, confidence score, ranked matches, and a suggested test order.
- Overlapping symptoms across nutrients are normal — several deficiencies can genuinely coexist.
- This is a screening tool, not a diagnosis — use it to decide what to test, not to skip testing.
Frequently Asked Questions
It’s a screening tool based on documented symptom patterns and known risk factors, not a diagnosis. It’s designed to point you toward which blood tests are worth requesting, not to replace them.
Many nutrients support overlapping body systems, especially energy production and immune function, so fatigue or frequent infections can show up across several different deficiencies rather than pointing to just one.
Yes, and it’s common — iron and B12 deficiency often overlap in vegetarians, for example. This is exactly why the finder shows your top matches rather than a single answer.
No. All matching happens directly in your browser. The optional Save Profile feature stores your answers only on your own device.
It reflects how many symptoms and risk factors you provided. More input generally produces a more reliable pattern match, so a low confidence score means the result should be treated as a rougher estimate.
It visualizes your match percentage across all 6 nutrients at once, so you can see your overall pattern shape rather than just a ranked list — a wide, spread-out shape suggests multiple overlapping gaps, while a sharp single point suggests one dominant match.
Follow the suggested test order for your top matches, read the full guide for each, and take actual test results to a doctor rather than starting supplements based on symptoms alone.
Yes, simply answer based on their symptoms and risk factors instead of your own — the tool doesn’t collect any identifying information either way.
