RDA

The RDA for copper is 900 micrograms for adults.

Meanwhile, most of us can barely remember what happened on last week’s episode of She-Hulk — when Avatar 2 hits theaters, there could be a lot of confusion if characters start talking about unobtanium, Toruks, RDA, or the Noble Clyde Boudreaux.

Most multivitamins contain 2.4 micrograms, the RDA for adults, but some people may need more, experts say.

The RDA is a tax escape hatch baseball owners enjoy for 15 years in which they can write off the massive salaries they pay their players.

Their RDA expired in 2021 or 2022.
