Is the long lasting caffeine debate coming to end? European Food Safety Authority, has just completed its assessment on safe levels of caffeine from diet in response to a mandate addressing concerns on consumption of caffeine containing foods and their interaction.
The Panel, considering risks from all dietary sources for the first time, concluded that levels up to 400 mg/day are considered safe for the general population.
Moreover, single doses up to 200 mg of caffeine do not raise health concerns, even when assumed before intense physical activity or together with taurine and D-glucurono-γ-lactone in commercial energy drinks. Additionally combination with moderate alcohol consumption (up to legal limit for car drive ability) does not generate extra health alarm.
For pregnant women, however, precaution is confirmed and upper daily intake should not exceed 200 mg/day and for children and adolescents, although available data are insufficient to estimate a safe intake level, levels could be derived from daily dose per kg bw per day for adults.
EFSA looked also at possible interactions with p-synephrine (substance present in some supplements for weight-loss), but judged that more investigation should be performed due to lack of adequate data.
