Phosphorus

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 phosphorus 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 phosphorus 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 550 mg adults 18+, both sexes EFSA →
No upper limit established by this authority None established No EFSA UL established for phosphorus - no adequate data to derive a UL (EFSA NDA Panel, 2005). EFSA →

United States — NIH ODS / IOM

Recommended daily intake (RDA / PRI) 700 mg adults 19+, both sexes NIH ODS / IOM-DRI (NASEM) →
Tolerable upper intake level 3000 mg adults 71+, total intake from all sources (tabulated as 3 g/d) NIH ODS / IOM-DRI (NASEM) →
Tolerable upper intake level 4000 mg adults 19-70, total intake from all sources (tabulated as 4 g/d) NIH ODS / IOM-DRI (NASEM) →

“None established” means that authority examined phosphorus 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 Phosphorus

1 product whose label declares phosphorus, 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.

Times of day suggested in the app: Morning.

Food: the app records phosphorus as taken with food.

Recorded interactions

What a named source says about phosphorus 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. None of these says whether a combination is good or bad.

RelationshipWhat the source saysSource
Documented relationship with Calcium Calcium from foods and supplements binds some of the phosphorus in food and prevents its absorption. The competition runs both ways: net absorption of dietary calcium is reduced to a small extent by phosphorus intake, and the two minerals are co-regulated by vitamin D and parathyroid hormone.

Documented relationship with Vitamin D3 Vitamin D helps maintain adequate serum phosphate concentrations, which is part of how it enables normal bone mineralisation. Vitamin D and parathyroid hormone jointly regulate phosphorus metabolism. NIH ODS

Indexed studies

Stacky has 5 papers indexed against phosphorus, and none of them is published here. A study reaches this page only if its own title names Phosphorus 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 phosphorus 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.
