☕️Caffeine is one of the most widely used ‘supplements’ not only in sport but in everyday life too. There are a wide variety of foods and drinks that contain probably more caffeine than we realise. Health organisations globally recommend that most people can safely consume up to 300mg caffeine per day, around 3 cups of coffee. For pregnant women, the NHS has set the recommendation to 200mg caffeine per day after studies have found links between caffeine intake and low birth weight.
🏃♀️In an athletic context, caffeine is very useful for reducing perception of fatigue, and allowing exercise to be sustained at optimal intensity and output for longer periods of time.
🏥When consumed in larger amounts it can cause side effects such as tremor, increased anxiety and raised heart rate. There are also anti-doping rules surrounding its use, prohibiting the intake of very large doses that produce urinary caffeine levels of >15ug/ml. Caffeine is be toxic when consumed in exceedingly high doses.
