A twenty-nine-year-old personal trainer, Mansfield, ordered a 3.5-ounce pouch of caffeine powder, which he planned to use in supplement drinks. However, he made a small mistake while measuring the powder that cost him his life.

Anywhere between 0.002 and 0.01 ounces of caffeine powder is the recommended dosage. Anything beyond that amount of caffeine powder can negatively impact health. Mansfield, on the other hand, consumed over two grams of caffeine. According to a report by the BBC, he drank several ounces of caffeine powder, equivalent to 200 cups of coffee – a fatal amount.

As soon as Mansfield consumed his drink, he complained of chest pain and increased heartbeat. However, his heartbeat did not slow down. Instead only drummed harder. Soon, foam started coming out of his mouth. Seeing his worsening condition, his wife immediately called an ambulance. However, his situation deteriorated with every passing second, and he soon went into cardiac arrest: his heart stopped pumping. Later that day, Mansfield was pronounced dead.

On deeper study, doctors discovered that the caffeine level in Mansfield’s blood was more than 350 mg per litre. On the contrary, usually, the caffeine level in the blood after consuming a single cup of coffee is anywhere between two to four mg per litre.

Unlike caffeine-based beverages, caffeine powder can be more dangerous because they are more potent. In fact, in 2015, the US Food and Drug Administration informed many such companies that sell caffeine powder about the dangers and risks to the consumer because of the consumption of the powder.
