How Long Does Red Bull Last? (Answered)

How Long Does Red Bull Last? (Answered)

It’s always necessary to know the duration of a product’s effects. You may also wonder if the product can live up to your expectations or estimates.

In the USA alone, there are claims that Red Bull has a hold on 24.6% of the consumer market. This means that Red Bull is a major player in the industry, but does this mean you can lean on it during your daily activities?

Red Bull’s ingredients are fully absorbed into your bloodstream and the effects gradually reduce after that time. The half-life of caffeine is approximately 5 hours, meaning that you’ll still have 40mg of caffeine in your system at that time. The ingredients will be completely out of your system after 24 hours.

And if we’re talking about shelf life, then you’d be happy to know that Red Bull can last more than a year. But of course, you’d need to properly store it appropriately for the can to last that long.

Keep reading to learn more about Red Bull’s effects on your body and how long they last.

Red Bull Ingredients

  • Carbonated Water
  • Sucrose
  • Glucose
  • Citric Acid
  • Taurine
  • Sodium Bicarbonate
  • Magnesium Carbonate
  • Caffeine
  • Niacinamide
  • Calcium Pantothenate
  • Pyridoxine HCl

Red Bull uses a preservative called Citric acid. This element is used to give products longer shelf life. In fact, cosmetics products also make use of this. 

On another note, Red Bull didn’t specify what its natural and artificial flavors are. But some brands do the same thing too, so it’s nothing out of the ordinary.

Red Bull Nutritional Information

Aside from the mentioned ingredients, Red Bull contains the following nutrients:

Niacin100% of the recommended daily intake
Vitamin B6250% of the recommended daily intake
Vitamin B1280% of the recommended daily intake

What Does Red Bull Do To Your Body?

Of course, it can energize your body mainly because of its caffeine content. Like most energy drinks, after taking Red Bull, the first ten minutes will cause an increase in your blood pressure. After an hour, you’ll feel the surge of energy at its peak. 

Here’s a video that could explain to you what exactly does energy drinks do to your body.

Other Energy Drinks actually work just the same.

How Does Red Bull Give You Energy?

Caffeine acts as a stimulant that energizes you. Since Red Bull has 80 mg of it, I’d say that’s pretty minimal and won’t cause many side effects.

In addition, Red Bull also has 27 grams of sugar that can serve as fuel as you go through the day’s activities. That’s kind of a hefty amount for me already, but if you regularly do workouts, then you’d be able to burn all that sugar.

Lastly, Red Bull also contains Taurine, which is a nutrient that also improves your mental and physical performance.

While we don’t know precisely how much taurine is in a can of Red Bull, this article states that 3000mg of taurine is still safe.

How Long Does It Take for a Red Bull to Wear Off?

If the peak level is around 60 minutes after intake, Red Bull’s effect wears off four hours after taking it. However, you may not feel the stimulating effects of caffeine by then, but it’s still there. 

If you don’t know already, caffeine has a half-life. This article defines this as half the original amount of the substance left in your body after 5 hours

Therefore, if you drink a can of Red Bull right after 5 hours, right after the peak is gone, you still have 40mg of caffeine left within your system. You don’t have to worry much, though. This would just disappear within the next 5 hours.

How Long Does Red Bull Last Once Open?

Well, even after you open it, it’s still safe to drink for at least two to four days. However, I think you should leave it inside your refrigerator if you won’t be finishing the whole can.

On the other hand, leaving it in an open space might jeopardize its safety, especially if you leave it open without any lid for hours or days. Flies may have gone in and out of the can, for who knows. 

Before you open it, I suggest you check its expiry date indicated on its can too. It’s said that the expiry label will run between twelve to twenty-four months after it was fabricated. This is why you should always check its manufactured date and best before date.

How Many Red Bulls Can You Drink In A Day?

I think one can to two cans is enough. But of course, that will still depend on your tolerance. If you feel like taking one can is too much for your body, don’t think of having anymore.

The FDA doesn’t specify how many cans are safe for a day for energy drinks. However, just by looking at their guidelines regarding caffeine, they say it’s safe to consume only 400mg of it per day.

Having too much caffeine in your body can dehydrate you and make you suffer from caffeine overdose. You can also encounter other side effects such as:

  • Headaches
  • Nervousness
  • Palpitation
  • Hallucination
  • Anxiety
  • Nausea

The calorie content of Red Bull is another thing to check. First off, the recommended daily calorie limit for adults is between 1,600 and 3,000 calories per day.

I guess Red Bull’s 110 calories won’t cause you to gain extra weight. Except when you’re daily meal is over 3000 calories per day. Besides, you can quickly burn 110 calories by swimming and jogging.

Can We Drink Red Bull On An Empty Stomach?

You can, but you shouldn’tDrinking energy drinks on an empty stomach can ruin your metabolism and digestive functions. A shocking finding states that drinking energy drinks on an empty stomach can cause Transient Ischemic Attacks.

This is sometimes called a mini-stroke. Although you can recover from it without any intervention, this could be a warning that you might develop a full stroke in the future. 

Therefore, even if you need that boost, eat a proper meal first. You might also resort to a healthy diet to prevent other health issues such as heart disease, diabetes, and cancer.

Can You Be Addicted to Red Bull?

You can be addicted to anything with additives, especially if it tastes great. As you know, Red Bull’s sweet soda-like taste is appealing for most. 

Red Bull has 27g of sugar, and according to this article, you should only have 30g of sugar on your body daily. Any more than that could lead to sugar crashes which won’t benefit your workout.

This means you should be wary of its sugar content along with the caffeine content. Otherwise, you may experience side effects related to sugar and caffeine.

Alternative Energy Drinks to Red Bull

Like I’ve said, Red Bull isn’t the only energy drink that can give you energy for long hours of gaming. If you want to go for something different, you can consider these: 

Aspire Energy

Just like Red Bull, Aspire energy has 80mg of caffeine too. However, I think this is a better option than Red Bull because it’s sugar-free and calorie-free!

It’s also loaded with vitamin Bs, sodium, and calcium to strengthen your performance. More than that, it also keeps your fluid balance and bone health. I like this energy drink because it claims to be vegan-friendly as well.


You can try this if you’re more of a caffeine person and you sweat a lot. You might have heard that Bang energy has 300mg caffeine. This energy drink is also packed with electrolytes and minerals, which would help keep your body fluids stable.

Moreover, it also has amino acids that’ll increase alertnessfocus, and endurance. While it contains no sugar and few calories, its caffeine content is something you should watch out for. 

REIZE (Top Pick)

In contrast with Bang, REIZE’s caffeine is at 50mg only. While you might think it won’t have any effects on your body, this isn’t so. It has a palpable push that could last just as much as Red Bull.

Moreover, it’s packed with nutrients you cannot find in Red Bull, such as ginseng and inositol. REIZE is also sugar-free with only a few calories. Therefore, you won’t have to worry about having a sugar crash or caffeine overdose.

The Final Say

The energy you’ll get from Red Bull is incredible, especially during the one to four hours after consuming it. I think that’s already enough time for an exercise session. Plus, you can still use some of the energy left for errands.

Therefore, if you have a low tolerance for caffeine, chances are you would feel the side effects much earlier than others who don’t. However, you’re less likely to feel this from Red Bull because its caffeine content is pretty modest.

That said, the side effects may differ for each person. Just in case you face any, consult your doctor right away.
