What regulators and scientists say

• EFSA set an acceptable daily intake of 0.5 mg per kilogram of body weight per day (April 1, 2014). For a 70 kg (154 lb) adult, that’s about 35 mg a day.²
• The FDA lists it as generally recognized as safe (GRAS) for its intended use in food (21 CFR 184.1660).¹

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
