5-hour energy may contain more caffeine than advertised, but it is still probably a safe, albeit pricey, alternative to a coffee boost for those who can tolerate caffeine.None of the other ingredients appear to have any effect on energy or alertness except in rare cases of deficiency or nutrient depletion, and there is no scientific basis for the claim that the increased energy will last longer than it would for a similar amount of caffeine consumed in a different beverage. The B vitamins might also help improve concentration and alertness, but these effects have only been researched in the context of daily multivitamin use and the amounts provided in 5-hour energy are much higher than needed. Caffeine reduces sleepiness, enhances alertness and restores cognitive function lost due to lack of sleep. The active ingredient in 5-hour energy is caffeine, plain and simple. Because these compounds occur abundantly in beans, meats and many processed foods, deficiency is uncommon and there is zero evidence that consuming these compounds can improve alertness or cognitive performance unless a person has a severe deficiency. Other stuff: A mixture of several metabolic byproducts and amino acids such as phenylalanine, tyrosine and citicoline (a derivative of choline) which the company calls an “energy blend.” These components are all associated with energy and metabolism in the body.Since this drink contains no sugar, it will not produce a sugar crash common in some other drinks. This ingredient is buried in the ingredient list, so you may not have noticed that before. Sugar substitute:The drink is sweetened with sucralose (otherwise known as Splenda©) to give it a sweet taste.This is even more likely if you already take a multivitamin that contains B vitamins (especially B3 and B6). If you experience hot or tingling skin and/or numbing sensations, you may have overdosed on B-vitamins. All of the B vitamin levels in one 5-hour energy drink are below the maximum daily intake level, but since many students who use energy drinks tend to use more than 1 in a day, you may consume more than the recommended maximum level. Extremely large amounts of B vitamins (8333% of the daily value for one B vitamin): While a few recent studies have suggested that taking a daily multivitamin (with B vitamins, vitamin C and minerals) for 30 days leads to improved concentration and alertness, large amounts of these vitamins are not required to produce an effect.While caffeine is generally safe (even when consumed daily) there is also scientific consensus that it affects your sleep pattern, and may cause you to be more anxious, especially if you already experience anxiety. Plenty of caffeine: Despite the claims on the label, some independent laboratory tests have shown that 5-hour energy contains up to 200mg of caffeine while an average cup of coffee contains just 130mg.What’s in 5-hour energy? Caffeine, B vitamins, a sugar substitute and some other stuff. 5-hour energy, a popular energy drink you may have tried, makes claims that seem too good to be true… Get immediate energy that lasts for 5 hours, without a sugar crash afterwards and with the same amount of caffeine that is in one cup of coffee.
