Does anything boost your energy?

It's not the Caffeine in the drink that's the main incredient. Phenylalanine, Taurine, Glucuronolactone, Malic Acid, Tyrosine, and Citicoline are also present to supposedly boost alertness. The Caffeine is the quickest-acting of the list, and I'm suspect of the Taurine and Phenylalanine as being huge contributors to "energy" per se, but it seems the drink relies on a huge B-vitamin mix and the aforementioned ingredients to promote alertness and awake-ness.

Does it work? Well, it does on me (with qualifications). I grabbed one a couple months ago, skeptical of the stuff but beginning an all-nighter on some stuff at work, so I picked one up as a test. There's no real "energy" boost if what you're looking for is the caffeine burst or jitters, but it certainly helped keep off the 3AM sag from tired-ness being up all night. In fact, if I had to gauge its effects for a time frame of effectiveness, I'd say I was pretty good to go for about six or seven hours into the all-nighter before I started feeling the normal fatigue from being up way too long without sleep. The 5-Hour shot isn't going to give someone any boost above their normal operating condition, but if taken prior to or during a period where fatigue is setting in, the drink helps keep the fuzzy edges from closing in and hampering your alertness-- to a degree. It's not some kind of magical potion, and I'd strongly urge someone to follow the company's suggestion of taking a half-bottle first and saving the rest for later if needed, but I can speak to its efficacy with my own experience. Definitely worth the $3 for the night.

Just bear in mind that while their "energy" name and advertising is all well and good, what you get from it isn't "energy" as much as it is "sustained alertness" and possibly (for some) a bit of flushed skin due to a high dose of Niacin in the drink. It's not a substitute for real energy-producing fuel for the body-- meaning food, particularly the healthy kind. For those who might be experiencing a case of the "blahs" some morning or who feel like they didn't quite get enough sleep the previous evening, it'll help you out (some) in that you'll feel less "blah" and able to operate at your normal level of alertness. It doesn't give you anything that your body isn't already capable of or doesn't already have, so expecting a rush of energy is going to lead to disappointment with this stuff. It works, but not like you'd expect from its advertisements, though I'm sure they have a marketing department who'd love to correct me for my saying so. Use at your own risk, and be sure to read the print on the bottle (even the small stuff) before giving it a glug.

Note: this stuff has a huge shot of B-vitamins, including more than %8,000 higher than the daily recommended value of B-12 in just one shot. It's not something I'd recommend as a regular supplement for a normal, healthy adult (and not at all for children), because it's not meant for that purpose. People who are older or who have B-12 or B-6 deficiencies (not typical or likely if your reaction is "I don't know") might benefit from it, but there are far more reasonable medical avenues to address such things.

Are you suggesting that if a person ate 2000 calories of a balanced diet and burned those 2000 calories he would be thinner than a person who ate 2000 calories of crap and burned those 2000 calories? That's against the law.

No. You're assuming that all calories are equally accessible (which we know isn't true, hence the development of the glycemic index).

If I eat 2000 calories of low GI foods, I'll end up burning off a non-trivial fraction of the calories in processing the food to extract the calories from it, even if I'm doing identical work to the person who ate 2000 calories of high GI foods. So even though we do the exact same things and therefore expend the exact same amount of external work, I actually burn more calories and stay thinner.

Also, over an extended time a diet of just cake is likely to result in some muscle loss and a reduced basal metabolism, I think, compared to a healthy diet.

I think we need a double-blinded, controlled trial.

That "5-Hour" energy drink says it only contains 4 calories, and appears to be mostly vitamins and caffeine. I can't see how that's going to "boost" anyone's energy, but lots of people seem to drink it.

I'd not heard of these. I was always just under the impression that they were all calorie-loaded drinks with excessive levels of caffeine (or similar). Indeed, if there's only 4 calories it's going to do almost nothing to your actual "energy" level, just affect the way your body functions and uses its existing energy.

Does caffeine have any caloric content? ie. does it have any "energy"?

bokonon said:
Caffeine doesn't really boost energy, it just keeps you awake so you can burn more of the energy you already have.

This was equal to my understanding. Not an increase of energy at all, but a modification of your bodily function, changing the way you use that energy.

I'm not opposed to it. Do we also control for different states, say fatigued versus well-rested? I qualified my statements because 1) they're anecdotal and 2) "energy" isn't exactly what you're getting with the drink.
