The correct option is Estimated Average Requirement.
The estimated average requirement (EAR) is the number of nutrients that, according to estimates, will satisfy the needs of 50% of people in a given life stage and gender group. For both men and women, balance tests and data on stable isotopes point to an EAR of 5 mg kg per day. It is believed that this threshold, which is higher during teenage growth, is 5.3 mg kg1 day1. A supplement of 35 mg per day is advised since the Mg demand increases during pregnancy due to Mg transfer to the fetus in the final three months. The adequate intake (AI) for newborns is calculated based on the Mg content of breast milk and the progression of solid food ingestion.
