How many grams of protein does an 87 year old woman need in a day?

dependongon your weight, generaally 1 gram/kg/day is enough

so if you weight 176 pounds=80kg=80g/day is enough but you can eat more but i dont suggest eating more than 2g/kg/day


if you have kidneyproblems eat less like 0.6-0.8g/kg/day (60g/day), etc.
