Vitamin B2
What the European Food Safety Authority and the United States National Institutes of Health have published about vitamin B2 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 vitamin B2 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
United States — NIH ODS / IOM
“None established” means that authority examined vitamin B2 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 Vitamin B2
4 products whose label declares vitamin B2, 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.
Food: the app records vitamin B2 as taken with food.
Recorded interactions
What a named source says about vitamin B2 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: 2 such rows for Vitamin B2 stay in the app. None of these says whether a combination is good or bad.
| Relationship | What the source says | Source |
|---|---|---|
| Increases absorption or status of Vitamin B6 | Converting vitamin B6 to its active coenzyme form, pyridoxal 5'-phosphate, requires FMN, which is made from riboflavin. Low riboflavin status therefore affects how much vitamin B6 is available in its active form. | NIH ODS Checked 6 Aug 2026 |
| Increases absorption or status of Vitamin B9 | Riboflavin is the precursor of FAD, the cofactor for MTHFR, the enzyme that produces the active circulating form of folate. The link is described as strongest in people carrying two copies of the common MTHFR c.677C>T variant, who typically show low folate status. Scope the source gave: effect is largest in people homozygous for the MTHFR c.677C>T variant. |

Indexed studies
Stacky has 5 papers indexed against vitamin B2, and none of them is published here. A study reaches this page only if its own title names Vitamin B2 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 vitamin B2 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.
