There are no guidelines on this that I’m aware of, but it seems unlikely that the RDI scales linearly with lean body mass. Some proportion of micronutrient intake goes towards the likes of bones and organs and the brain, which is unchanged by having more muscle mass.
I’m less confident of this than I am of the opposite framing: people with a low caloric intake have to be more careful about eating nutrient-dense food.
Typically, if you are “overweight” you can multiply your age’s RDI by 1.5, and if you are “obese”, you can multiply your age’s RDI 2-3 times, and these numbers are an idea of what your daily recommended amount should be.[3] For example, the RDI for a 30-year-old is 600 IU. If that 30-year-old is overweight, then they should be taking close to 900 IU daily. If that 30-year-old is obese, they require 1200-1,800 IU daily. For an adult, doses up to 4,000 IU are considered safe.[4]
