What does Apple Health dietary manganese measure?
Dietary Manganese stores the amount of manganese recorded as consumed from food or supplements. Each entry contributes to a cumulative intake total. Apple's type definition uses mass units. This page's display unit is mg; a nutrient amount is distinct from the weight of the food or tablet. It is not a blood concentration or a measurement of body stores.
Does this track environmental manganese exposure?
Dietary Manganese records an amount consumed. It does not record inhaled occupational exposure or manganese measured in blood. The fraction absorbed varies with intake and other factors, including iron status. NIH's manganese review explains why a food amount is not an absorbed dose.
What should I check before adding the entries?
| Question | What to inspect |
|---|---|
| Manganese or magnesium? | These are different nutrients with similar names; verify the selected HealthKit type and mg versus mcg. |
| Could the unit explain a large value? | 1 mg equals 1,000 mcg; check the source value before conversion. |
| Can two apps be combined? | Look for the same food or supplement imported twice; preserve provenance. |
| Does a missing day mean no intake? | No. Food may have been consumed without a record, or the nutrient field may be unavailable. |
A source-specific daily sum answers how much was recorded on that reporting day. It does not establish a complete diet. Keep the number of logged days visible and leave unrecorded days missing rather than filling them with zero. A population intake recommendation is a daily dietary planning value, not a normal range for a single sample.
How often are records created?
Recording cadence follows the contributing app or manual log. Entries can represent servings, retrospective meals or an imported daily total. Several records saved together need not mean several doses were consumed simultaneously. Sample start and end times describe the source's interval; they do not independently verify ingestion time.
A late-night entry may simply be delayed logging. Investigate source behavior before assigning a meal time or combining records from different sources.
Is example data available?
The 365-day reporting window contained no raw manganese samples, stored aggregates for this type. Ranges, outliers, logging intervals and empirical nutrient relationships were therefore unavailable. No measured distribution or graph is presented. Missing records do not establish zero intake or deficiency.
The current PulsHealth sync catalog does not include this identifier. A knowledge-base page documents a HealthKit type; it does not establish that the current app synchronizes it. This coverage limitation is separate from what may exist in Apple Health or another food app.
How should I relate this to other health data?
An iron intake log describes another nutrient consumed; it is not a ferritin test or a measure of iron stores. Even complete paired food logs would not allow calculation of manganese absorption. Review dietary records and environmental exposure histories separately.
How can I make future records more useful?
Check that the app actually writes this nutrient to Apple Health, then inspect a known food or supplement entry. Retain serving counts, units and source information. Optional food metadata can help identify a contribution, but does not guarantee a complete meal or identify supplement chemistry. Apple's data-source controls explain how to review contributing apps. If an intake comparison raises a concern, establish logging completeness before interpreting it clinically.
Understanding your records
Recording frequency, source and coverage affect what you can conclude from this data. Read the recording guide.
- One record
- Cumulative recorded nutrient amount in compatible mass units; not a blood concentration or absorbed dose.
- Frequency
- Source logging or import intervals; ingestion cadence is unverified.
- Context
- Check food or supplement items, serving quantities and mass units before combining sources; the log describes recorded intake rather than measured nutrient status.
- Coverage and gaps
- Nutrient availability varies by source food database and export support. No records does not establish zero intake.
- Summaries
- Sum compatible contributions by source and reporting day after checking servings, units and duplicate imports; report logged-day coverage.
- Metadata
- Optional food descriptions cannot recover missing serving details, chemical forms, fortification or absorption.
