Functional compound

Beta-carotene

Beta-carotene is a plant pigment that the body can convert into vitamin A. That makes it a vitamin A precursor, rather than a separate essential vitamin.

What it does, and how

Follow the conversion to vitamin A

Vitamin A activity from beta-carotene is accounted for in retinol activity equivalents, or RAE. The Kale profile already includes vitamin A RAE, so its beta-carotene amount must not be added to that value again.

Where it works in the body

A nutrient can take part in more than one body system. Follow a connection to see how its work fits together with other nutrients.

Source-backed body-system relationships will appear here.

Reference food in our crop catalog

Reference composition

Basis: raw edible food, per 100 g. % DV uses FDA Daily Values for adults and children 4+ where one exists; values above 100% are shown without capping. Reference amounts describe the USDA food, not a UCFarms harvest. “No DV” means there is no applicable Daily Value or conversion.
