Many fitness enthusiasts follow a strict regimen that includes everything from daily creatine use to post-workout protein shakes.
And that’s just the supplements; the actual gym routine is equally important.
For many, a workout doesn’t truly begin until they’ve consumed their pre-workout drink, which is usually a caffeine-rich concoction.
In recent years, pre-workout supplements have gained popularity, transitioning from the elite sports domain into mainstream fitness culture, similar to the rise of creatine. However, like many other supplements, they come with potential side effects.
Recently, a doctor addressed the risks associated with caffeine, particularly powdered forms, in a YouTube Shorts video.
Though his videos are not a substitute for professional medical advice, Dr. Sermed Mezher is a respected academic and purveyor of quality scientific content.

The Doctor’s Advisory
Dr. Mezher explained, “It’s quite challenging to consume excessive caffeine through coffee, but powdered forms are an entirely different scenario.”
Dr. Mezher pointed out that many pre-workout supplements now utilize powdered caffeine, dispelling the myth that “more caffeine equals better performance.”
He emphasizes that this is not always true.
In fact, he notes that consuming too much caffeine can lead to serious side effects such as a rapid heart rate, tremors, hallucinations, and even seizures.
Dr. Mezher further elaborated, “To get the same caffeine content from coffee, even with double espressos, one would need to drink around eight cups to hit over a gram.”
“Conversely, with powdered forms, you only need a few scoops.”
Thus, while he acknowledges the benefits of pre-workout supplements, he stresses the importance of consuming them responsibly.

Advantages of Pre-Workout Supplements
Pre-workout supplements can undeniably enhance your performance during challenging gym sessions, making them especially beneficial for those who work out early in the morning or after a long day.
Rob Hobson, a registered sports nutritionist, shared with Men’s Health: “The primary performance benefits come from ingredients like caffeine, which is known to enhance alertness and endurance, along with carbohydrates that provide the necessary fuel for your muscles.”
Overall, taking pre-workouts can optimize strength, improve endurance and focus, and increase energy levels during training.
FSA Guidance
In 2024, the Food Standards Agency (FSA) provided new guidelines regarding food supplements containing caffeine.
According to the FSA, “Caffeine is swiftly absorbed into the bloodstream, and its stimulatory effects may start 15 to 30 minutes after consumption and can last for several hours, potentially leading to side effects such as headaches and nausea.”
The agency recommends that caffeine intakes of up to 400mg per day are generally safe for most individuals.
They issued a warning stating: “High caffeine consumption can cause anxiety, sleeplessness, agitation, heart palpitations, diarrhea, and restlessness. Those with pre-existing mental health conditions may experience worsened symptoms. These adverse effects can be more pronounced in individuals sensitive to caffeine or with underlying health concerns like heart disease or high blood pressure, and may occur at lower doses.”
The FSA also noted that excessive caffeine intake is linked to serious side effects such as rapid heart rate, irregular heart rhythms, and seizures, which have been documented at doses around 1.2 grams (1,200 mg) of caffeine. Fatalities have occurred at caffeine levels exceeding 10-14 grams (10,000-10,400 mg), although even smaller amounts can be dangerous for sensitive individuals. These incidents often arise from incorrect measurement while using pure caffeine.
Therefore, it’s crucial to carefully read product labels and factor in other sources of caffeine, including tea, coffee, and energy drinks.
In conclusion, while pre-workout supplements can offer significant benefits for enhancing gym performance, caution is essential. Monitoring your caffeine intake and understanding the potential side effects can help ensure a safe and effective workout experience. Always consult with a healthcare professional for personalized advice tailored to your health needs.
