It's remained popular for a reason — Red Bull is still the best energy drink out there. It's a bit more expensive than many competitors, but tastes great and works very well.
Tastes good — consuming too much can be a problem at 110 calories each. Also, people mix this with alcohol and that can be a dangerous combo.
Better price than a lot of competitors and gets the job done.
Taste not as popular as those offered by competitors. 100 calories — a bit high for someone using this for energy to exercise.
Only four calories per serving. Not filling — it's a shot instead of a whole drink. Plenty of flavors to choose from. Concentrated, effective energy boost.
A bit on the expensive side.
Unique among energy boosters — just dump a tube in a bottle of water, mix, and you're ready to go. Just 10 calories per tube. Variety of flavors, too.
Weird, metallic aftertaste. Not as high a boost as a lot of competitors.

Energy drinks are formulated to deliver a boost of energy when you need it most. In most drinks, this is the result of two main ingredients: caffeine and sugar. Caffeine is a central nervous system stimulant that increases alertness, reaction time, and concentration. Sugar gives you a quick burst of energy by raising your blood sugar level.
In addition to caffeine and sugar, energy drinks usually contain other ingredients like ephedrine, taurine, ginseng, and guarana that are meant to increase your wakefulness and endurance.
Popular for a good reason
It’s not a coincidence that Red Bull Energy Drink is the energy drink of choice for many athletes, students, and hard-working professionals. It contains enough caffeine to help you feel more awake and alert, as well as real sugar to provide carbohydrates that replenish energy. We also love that the formula includes B vitamins that can help with carb and protein breakdown and boost metabolism.
Let’s take a look at several key reasons why energy drinks are so popular.
Energy boost: The most obvious benefit from an energy drink is that it makes you feel more awake and alert. This is particularly helpful if you haven’t had much sleep and need to go to work or school. Energy drinks are also helpful if you need an energy boost for a specific project, such as studying for an exam or finishing a presentation.
Specific amount of caffeine: The amount of caffeine in coffee and tea can vary from type to type, so you can never be sure how much you’re getting. With an energy drink, the caffeine amount is printed right on the packaging, which allows you to limit your intake if necessary.
Fast acting: Energy drinks are typically consumed cold, which makes it easier to drink them quickly. Coffee and tea, on the other hand, are usually hot, so you have to sip them, which means it takes more time for the caffeine to work its way through your system.
Variety of flavors: If you’re not a fan of the taste of coffee, energy drinks are an ideal alternative because they come in a wide range of flavors, making it easy to find an option that you like.
If you’ve never had an energy drink before, it’s usually best to start with half a can or bottle and only drink more if you need additional energy.
Limit your intake of other caffeinated beverages like coffee or soda when you drink energy drinks.
For the healthiest option, avoid energy drinks that contain high-fructose corn syrup, which is a highly processed sweetener.
While caffeine is the main ingredient in most energy drinks, you want to be sure it’s a healthy amount because too much caffeine can leave you feeling jittery and agitated. Experts recommend ingesting no more than 400 milligrams of caffeine per day. Avoid any energy drinks that don’t disclose their caffeine content on the label. Look for drinks that contain no more than 300 milligrams of caffeine per 16 ounces.
Sugar is another key ingredient in energy drinks, but too much sugar in your diet can lead to diabetes, obesity, and other health problems. To make sure that an energy drink is as healthy as possible, look for options with no more than 10 grams of sugar per serving.
Energy drinks aren’t regulated by the Food and Drug Administration, so it’s important to understand the other ingredients and supplements that are commonly found in them. Some of the most common energy drink ingredients include:
Ginseng: Ginseng is an herb that is thought to boost energy. However, studies show that it can actually decrease your endurance during exercise. It also lowers blood sugar, so ginseng shouldn’t be consumed if you’re on diabetes medication.
Guarana: Guarana comes from the seeds of the South American guarana plant. It contains twice the caffeine as coffee.
Taurine: Taurine is an amino acid that supposedly speeds up your metabolism and increases athletic performance. You shouldn’t consume more than 3,000 milligrams per day, though.
Carnitine: Carnitine is an amino acid that can boost fat-burning and endurance. You shouldn’t consume more than three grams per day, or you may develop an upset stomach or, in more serious cases, seizures.
Green tea extract: Green tea extract delivers a minimal amount of caffeine. It also contains antioxidants that fight cancer.
Green coffee extract: Green coffee extract delivers caffeine without the coffee flavor.
B vitamins: B vitamins, including B6, B12, niacin, and folic acid, can help boost energy. They are water-soluble, though, so they don’t stay in your system long.
Ginkgo biloba: Ginkgo biloba is derived from the leaves of the Chinese ginkgo tree. It is thought to help boost memory and ward off mental fatigue.
Many people don’t think about the calories that are in the beverages they drink, but a sugar-laden energy drink can pack plenty of calories. Check out the calories in any formula that you’re considering, and stick to those that have 150 calories or less.
When they first hit the market, energy drinks had a reputation for a pretty unpleasant, medicinal taste. These days energy drinks are available in a wide range of flavors, so it’s easy to find one that appeals to you. Some common flavors include berry, orange, lemon-lime, citrus, and tropical punch. Try a few to see which flavor is your favorite.
Most energy drinks come in cans or bottles that contain eight to 16 ounces. However, some energy drinks are smaller in size, containing two ounces or less. These concentrated formulas are meant to be consumed in a few gulps, like a shot, to provide energy as quickly as possible.
Great taste and fewer calories
Unlike other energy drinks with funky medicinal flavors, Monster Energy Drink has a smooth taste that goes down easy for energy fast. And although it contains real sugar, this affordable energy drink boasts only 100 calories per eight ounces, making it a healthier option than many other brands on the market.
Energy drink prices vary based on the size of the cans or bottles and the number of cans or bottles in a pack.
A single 16-ounce energy drink usually costs between $1 and $5. Smaller, two-ounce energy drink shots usually run from $2 to $6.
A 12-pack of 16-ounce energy drinks usually costs between $10 and $28. A 24-pack of 16-ounce energy drinks usually runs from $20 to $40.
A 12-pack of two-ounce energy drink shots usually costs between $12 and $30. A 24-pack of two-ounce energy drink shots usually runs from $28 to $53.
Q. Are energy drinks safe to drink?
A. If you consume energy drinks in moderation, they are usually safe to drink. Try to limit yourself to just one per day. It’s important to keep an energy drink’s caffeine content in mind, and avoid consuming more than 400 milligrams a day if you’re an adult and 100 milligrams a day if you’re a teenager. However, if you have a health condition like high blood pressure or heart disease, you should consult with your doctor before consuming energy drinks.
Q. How long does it take to feel the effects of an energy drink?
A. It depends on how much caffeine the energy drink contains, how much you weigh, and what other foods and beverages you’ve recently consumed. However, it usually takes between 15 and 45 minutes for caffeine to reach peak levels in your bloodstream, so that’s when most people start to feel the energy boost.
Q. Are energy drinks effective for rehydrating during sports or exercise?
A. Unlike sports drinks, energy drinks are not formulated for rehydrating athletes during or after workouts. In fact, because they usually contain large amounts of caffeine, energy drinks are more likely to dehydrate you. If you want to rehydrate after a workout, choose a sports drink that contains electrolytes or just a bottle of water.
