What regulators and scientists say

• EU law requires foods containing it to carry the words “may have an adverse effect on activity and attention in children.”¹
• EFSA set an acceptable daily intake of 0.5 mg per kilogram of body weight per day (March 23, 2015). For a 70 kg (154 lb) adult, that’s about 35 mg a day.²

An acceptable daily intake is, in EFSA’s words, “an estimate of the amount of a substance in food or drinking water that can be consumed daily over a lifetime without presenting an appreciable risk to health.”³
