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. I feel like the Sugar Free Red Bull is pretty much just drinking a chemical cocktail, but I'm okay with that - for now.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. It works for me, but you have to experiment and see what works best for you. But, Monster makes little shots in small black bottles (it's like super concentrated Monster) that are about the size of 5 Hour Energy - I mix one of those with water in one of my water bottles to drink on the bike leg and during difficult training rides. I can't stand regular Red Bull or Monster. For some reason, the Sugar Free Red Bull doesn't upset my stomach, but gives me the kick I need. swim practices, and the rest on my way to work so I don't pass out at my desk. During training, I drink half of one on my way to early a.m. Still, I have a love affair with caffeine, so I drink a Sugar Free Red Bull on race mornings. ![]() Coffee is bad news until I've been up for at least 2 hours, and I've never really been into drinking coffee before any kind of race or game. I have to be really careful with what I eat and drink in the morning or my stomach freaks out. Ï¿½The greater danger for most of us is not that our aim is too high and we miss it, but that it is too low and we reach it.� -Michelangelo Amazing how frequently sucralose is used in today's products, how much of it humans consume, yet there aren't many human studies on it. It wouldn't be the first time that an artificial sweetener is first made available and considered "safe" only to be pulled years later. Research how they came to formulating sucralose in the first place. Research the side effects and safety of artificial sweeteners/sucralose/splenda. There aren't many human studies but there is much money to be made by having the FDA approve them for commercial use. "Sugar free redbull is perfect to settle my stomach."ĭo you know that sugar-free RedBull and many other "sugar free" (low calorie) supplements come with sucralose or other artificial sweeteners? I would not consume sucralose or other artificial sweeteners as I don't believe in their safety.
