The European Food Safety Authority (EFSA) has released a Scientific Opinion on the safety of caffeine for public consultation. Caffeine is a common constituent of energy drinks and similar products and concerns have been raised about the safety of high doses.
After reviewing the available scientific data on caffeine the EFSA Opinion concludes that single doses of up to 200mg and daily intakes of up to 400mg do not raise safety concerns for adults. However, single doses of 100mg could affect sleep patterns.
The expert panel concluded that a daily intake of 3mg per kg body weight is safe for children and adolescents. The also found that caffeine is unlikely to interact adversely with other ingredients in energy drinks.
The public consultation on the draft assessment will run until the 15th March and the Scientific Opinion can be found on the EFSA website here.
