What is a good vitamin to take for more energy?

The most popular energy boosters are B-12, Royal Jelly (and other bee-based products), L-Carnitine, Ribose, Ginseng, Guarana and Green Tea (both are natural sources of caffeine). For sake of simplicity, I would start with Siberian Ginseng (for mental and physical fatigue) and Royal Jelly as two cost efficient and effective products.

Most all of those are herbal or natural sources and are great for energy. I have used a few of them with great results and I have talked to many people who have gotten benefits from these products as well.

As far as brand is concerned, any answer given here will just be personal opinion (I can give you my opinion if you'd like). There are many higher quality companies out there that are readily available and well priced... just make sure the company has a good rating with either the GMP (Good Manufacturing Practices) or USP (U.S. Pharmacopoeia), as those are the main quality assurance organizations (USP is for the U.S., GMP is for the U.S. and worldwide).

No, I would NOT start with energy drinks at all. Those are mostly sugar and caffeine that add a few herbs because they are buzz words, but the ending result is still a crash after a short time, which makes it worse. I would avoid energy drinks and soda of any sort, but drink extra water instead... it doesn't taste as good, but it helps to keep your energy going longer.

Good luck and I hope I helped!

It really worries me that so many people seek scientific information from non-scientific people. I will bet $1 million dollars that nobody that has responded so far holds a degree in biology or chemistry. Even a bachelors degree. I am more than happy to point you in the right direction, regarding vitamins. Vitamins are necessary to facilitate certain processes in the body. If you are deficient in a vitamin, then that process can be interrupted and illness can occur. But more vitamins do not make the processes occur "better". The process either happens, or it doesn't. Therefore, if you have a specific vitamin deficiency, then supplementation will be beneficial to bring you up to healthy levels. If you don't have a deficiency, taking additional vitamins will not provide any increase in health, energy, or immune function. Common folk lore says that pumping up on Vitamin C will prevent a cold. That is simply false. Not only does it lack any scientific plausibility, but it has actually been proven false. Likewise, people take vitamins every day, because the word "vitamin" has a cultural association that implies "good for you". Therefore, people think that taking vitamin pills is like spinach to Popeye. Not the case. Usually, excess vitamins are simply excreted from the body as waste. But if you take very high doses for extended periods of time, vitamins can be harmful. Vitamin toxicity (hypervitaminosis) is a severe overdose of vitamins can cause serious health problems. Hypervitaminosis A can lead to birth defects, liver problems, osteoporosis, hair loss, etc. Hypervitaminosis D can cause dehydration, vomiting, kidney damage, hypercalcemia, etc. Hypervitaminosis E can lead to high cholesterol.

You're probably thinking, "how do I know if I'm getting enough vitamins?" Well, the fact is, in the developed world vitamin deficiency is extremely unlikely. You tend to see vitamin deficiency in underdeveloped regions of the world, or very specific isolated circumstances in the developed world. Even though most Americans don't have the "healthiest" diet, they are probably still getting plenty of vitamins.

Vitamin supplementation is one of the most common health misconceptions out there. The reason the medical community doesn't speak out about this more often is that vitamins generally aren't harmful, and its possible that someone out there might have a deficiency without them. In other words, minimal risk with a potential for benefit. But generally speaking, 99% of the population should not be wasting their money on these. What you SHOULD do is, eat a banana, then send your bottle of vitamins to malnurished children in Africa.

Many people react that way to the concentrated amount of vitamin C. Some people also feel nauseous from high levels of vitamin B.

Vitamin B - I can fully recommend Berocca daily (not just as a hangover cue !) plop fizz...bounce ! Its high on B and adds in small does of other esential vitiamins. Good health and way better than the energy drinks which tend to be very high in sugar.
