European Vitamin, Mineral and Proximate Dietary Reference Values (DRV, NRV, RDA)

Dietary reference values (DRVs) is an umbrella term for a set of nutrient reference values (NRVs) that includes the average requirement (AR), the population reference intake (PRI), the adequate intake (AI) and the reference intake range for macronutrients (RI). These values guide professionals on the amount of a nutrient needed to maintain health in an otherwise healthy individual or group of people. DRVs also include the tolerable upper intake level (UL), which is the maximum amount of a nutrient that can be consumed safely over a long period of time. 

RDA’s (Recommended Daily Allowance) were an old system and have now changed to NRV’s. The values for RDA and NRV are exactly the same.

Please contact our friendly and knowledgeable technical sales colleagues to help guide you to the best ingredients to allow you to achieve these recommended levels on your products.
