Questions about extracts of rosemary
Is rosemary extract harmful?
In 2018 EFSA estimated intake of E 392 from its use as a food additive: the largest mean was 0.09 mg/kg body weight per day and the largest 95th-percentile value was 0.20 mg/kg body weight per day, both in children aged 3–9; EFSA concluded that these estimates very likely overestimate real intake. The opinion also notes that in 2016 JECFA set a temporary ADI of 0–0.3 mg/kg body weight for rosemary extract, expressed as carnosic acid plus carnosol.
