To help us see what’s in our food when we’re shopping, and how this may contribute to our overall diet, food packaging often provides daily benchmark figures for nutrients. This benchmark – sometimes called the Nutrient Reference Value (NRV) or Reference Intake (RI). If a food label includes the amount of calcium in a serving, it usually shows how this contributes to the benchmark figure. For example, a product containing 200mg calcium in a serving may also state this is 25% of the NRV or RI.
Aside from these benchmark figures, there are also more detailed guidelines in the UK for calcium needs at specific ages and stages in life[7],[8].
