For adults 19 and older, the upper limit (UL) of vanadium is 1.8 mg per day, counting all sources together, food and supplements included. No UL is set during pregnancy or lactation. No UL is set for ages 14–18.

RDA = Recommended Dietary Allowance; AI = Adequate Intake, used where there is not enough data for an RDA. UL = Tolerable Upper Intake Level. “Not set” means the tables give no value. Ages under 14 are in the National Academies tables and are not covered here.
What counts toward the limit
This UL covers your total intake: vanadium from food and supplements added together.
Table footnote, as recorded in Ceiling’s data: “UL set for adults only, based on animal data; vanadium supplements should be used with caution.”
How Ceiling uses this
Ceiling adds up every supplement you scan and compares your daily total with this number. Ceiling counts supplements only, so food comes on top of the total it shows. Ceiling is coming soon on iPhone. No account; everything stays on your iPhone.
