The special review committee didn't get to caffeine until 1978 but they expressed serious concerns about its health risks that include high blood pressure with doses as little as 4 milligrams per kilogram body weight. In 1969, President Nixon ordered the FDA to re-review the substances on the GRAS list. The dose determines the relative safety of anything, as does what that chemical is taken with. No chemical, natural or synthetic, is 100% safe. I've always been wary of the so-called GRAS list. Caffeine was previously classified by the FDA as an additive "Generally Recognized As Safe" (or GRAS) at levels commonly used since 1958. In energy drinks caffeine is regulated as a food additive but its drug status is complicated by the fact that it occurs naturally in foods such as coffee and chocolate. We need to remember that caffeine is a drug, capable of providing us with mental alertness but at higher doses can make us anxious, shaky, and have gastrointestinal problems such as diarrhea. For example, younger (and smaller) people are more sensitive to the effects of caffeine and might also be taking other substances that could make the energy drink deadly. The major problem is that these reports don't list other very important information such as age, weight, pre-existing conditions such as heart disease, or any indication of drugs or dietary supplements that might have contributed to these adverse reactions. This is the question that FDA scientists are trying to assess. Phenylketonuria is rather common in the US, occurring in 1 out of 15,000 people but is three-to-five times more common in Turkey and Scotland.ĭoes this mean that 5-hour Energy caused the reported deaths and hospitalizations? In such individuals, the amino acid gets converted instead to a chemical that can cause seizures, and even mental retardation in developing infants and children. This is why you'll see diet sodas containing the artificial sweetener aspartame listed with a warning for phenylketonurics: aspartame contains phenylalanine. Among all of these components, I'm most concerned about phenylalanine, an amino acid that cannot be adequately broken down by people with a genetic disorder called phenylketonuria. They also contain various combinations of vitamins and amino acids, with some vitamins far exceeding recommended daily values. Is the problem only with the caffeine? What else might be dangerous in these drinks? But if you are a Starbucks fan, a 16-ounce serving (Grande) of their regular brewed coffee ( not espresso-based) there can average 330 milligrams of caffeine but range from 259 to a whopping 564! These are Starbucks' own reported values, levels that led to list this product's caffeine content as "Extreme."īut think about this: that high end for the "Extreme" content of Starbucks is roughly the same as only two small bottles of 5-hour Energy, perhaps telling us how deceivingly potent these "shots" can be. There you'll see that a large McDonald's coffee (16-ounce) has 145 milligrams of caffeine, just a bit less than the same as in a typical regular Rockstar or Monster product. One of the most comprehensive sources for caffeine content of beverages is this database at. Well, it depends on where you get your coffee. bottle (the "extra strength" only contains a bit more at 242 milligrams.). The more concentrated 5-hour Energy doesn't list its caffeine content but Consumer Reports recently determined that it contains 215 milligrams of caffeine per 2 fl. That's about three-to-five times the amount of caffeine in 12-ounce serving of a typical mass-marketed soda. Monster and Rockstar are brightly-labeled beverages that contain 160 to 175 milligrams of caffeine in drink sizes ranging from 5 to 16 fluid ounces. Rockstar was listed in 13 cases, none of which were deaths. Monster drinks were listed in five deaths and about 35 other non-fatal adverse reactions. The non-fatal reports extend back to 2005 and include typical symptoms such as dizziness, anxiety, and nausea all the way to seizures, brain hemorrhages, and heart attacks.
