Manganese

Minerals EFSANIH ODS / IOM-DRI (NASEM) 1 product in Stacky

What the European Food Safety Authority and the United States National Institutes of Health have published about manganese intake, and what the catalogue records. Reference figures and citations only.

Stacky is an organisational tool, not a medical device. It does not provide medical advice, and nothing on this page says what manganese does. Talk to a doctor or pharmacist before starting, stopping or changing what you take.

Published intake references

Each figure is one authority’s published value, with the kind of figure and the people it applies to as that authority stated them. Where the EU and the US differ, both are shown and neither is averaged or converted. Only a tolerable upper intake level sets a ceiling. A recommended or adequate intake is context, not a limit.

European Union — EFSA

Adequate intake 3 mg adults 18+, both sexes EFSA →
No upper limit established by this authority None established No EFSA UL established for manganese - insufficient data to derive a UL (EFSA NDA Panel, 2023). EFSA instead published a 'safe level of intake'. EFSA →

United States — NIH ODS / IOM

Adequate intake 1.8 mg adult females 19+ NIH ODS / IOM-DRI (NASEM) →
Adequate intake 2.3 mg adult males 19+ NIH ODS / IOM-DRI (NASEM) →
Tolerable upper intake level 11 mg adults 19+, total intake from all sources NIH ODS / IOM-DRI (NASEM) →

“None established” means that authority examined manganese and set no figure. A substance for which Stacky holds no published reference has no row here, and no page.

Products in Stacky’s catalogue containing Manganese

1 product whose label declares manganese, listed by brand and drawn as the app draws them. Amounts are the manufacturer’s printed figures; Stacky has measured nothing and ranks nothing.

How it is recorded

What the app records so it can schedule a dose. None of it is advice.

Forms recorded: Capsule.

Recorded interactions

What a named source says about manganese taken alongside another substance: absorption and nutrient status only. Each row links to its source. A row without one is not published, and neither is one whose source description names a disease or clinical condition: 1 such row for Manganese stays in the app. None of these says whether a combination is good or bad.

RelationshipWhat the source saysSource
Documented relationship with Calcium In one set of studies, supplemental calcium at 500 mg a day slightly decreased manganese bioavailability in healthy adults, with the size of the effect varying by the form of calcium. Several other studies found minimal effects of supplemental calcium on manganese.
Scope the source gave: 500 mg a day of supplemental calcium; effect varied by calcium form, smallest with milk and largest with calcium carbonate and calcium phosphate.

Documented relationship with Magnesium Supplemental magnesium at 200 mg a day slightly decreased manganese bioavailability in healthy adults, either by lowering absorption or by increasing excretion.
Scope the source gave: 200 mg a day of supplemental magnesium.

Indexed studies

Stacky has 5 papers indexed against manganese, and none of them is published here. A study reaches this page only if its own title names Manganese and does not name a disease or clinical condition. None of the 5 passes that rule. They remain in the app. How this list is built →

About this page

Stacky is a supplement tracking app. It renders what you take and what published sources say about it; it does not tell you what to take. Every figure on this page names the authority that published it and links to that authority’s own page.

Not on this page: a dose of our own, a grade, a verdict on whether manganese works, or any statement that it treats, prevents or improves a condition. How these pages are built →

Figures are read from the authorities’ published tables and can go out of date when those tables are revised. If one here is wrong, tell us at support@stacky-app.com and we will check it against the source.
