The Food Standards Agency (FSA) has introduced urgent new guidelines regarding the consumption of caffeine in food supplements following a tragic incident in the UK where a man passed away due to a caffeine overdose. The FSA, along with Food Standards Scotland, emphasised the potential dangers of highly-concentrated caffeine supplements such as caffeine powder, stating that they can be extremely powerful. Users are advised to strictly adhere to the dosage instructions provided on the label and use precise measuring equipment to avoid miscalculations.
The new guidance follows the case of personal trainer Tom Mansfield from Colwyn Bay, Wales, who tragically lost his life in January 2021 after mistakenly consuming a fatal amount of caffeine powder equivalent to approximately 200 cups of coffee. Mr. Mansfield had attempted to measure a dose of the powder within a range of 60 milligrams to 300 milligrams using a scale with a weighing range of 2 grams to 5,000 grams, resulting in the intake of multiple grams. In response to the incident, a cross-government working group has been examining broader issues related to the sale and usage of caffeine supplements, including initiating additional research.
A survey conducted for the regulatory bodies revealed that less than half of individuals check for dosage instructions on supplements, with 20% admitting they do not read the labels. The research also indicated that numerous consumers have limited knowledge about caffeine in food supplements. While caffeine is commonly utilised by some fitness enthusiasts to enhance performance, the FSA and FSS recommend that caffeine intake from supplements should be accounted for alongside other sources of caffeine like coffee, tea, and energy drinks.
The guidelines stipulate that caffeine consumption of up to 400mg per day is unlikely to cause adverse effects in adults, but pregnant women are advised to limit their daily intake to 200mg. Excessive levels of caffeine can lead to symptoms such as anxiety, sleep disturbances, agitation, palpitations, diarrhoea, and restlessness. Individuals with mental health conditions or underlying health issues like heart disease or high blood pressure may experience exacerbated side effects. Professor Robin May, the FSA’s chief scientific adviser, highlighted the importance of being aware of the caffeine content in supplements to prevent potential risks.
The FSA emphasised the significance of businesses ensuring the safety of food products and complying with labelling requirements to enable consumers to make informed decisions about their dietary choices. The guidance aims to raise awareness about the potency of caffeine supplements and promote responsible usage to prevent adverse health consequences. The agency also reiterated the importance of pregnant women monitoring their caffeine intake and checking labels for any warnings regarding unsuitability.
