How Long Does Caffeine Take to Kick in? (Informative) – REIZECLUB

Today more than ever, people crave their daily dose of caffeine. It is probably because of the increasing demands of our day-to-day activities that seemingly needs that sugar-rush kind of feeling of caffeine just to keep going.

This natural chemical comes in the form of coffee, tea, yerba mate, cola, guarana, candies, and a variety of other forms. But the newest source of caffeine in this modern world is energy drinks.

Normally, caffeine fuses in your blood generally between 15 and 45 minutes after ingestion. Once it does, your heart rate and blood pressure rise at that time.

Now, before you go all excited, caffeine is quickly metabolized by your liver and its stimulating effects will not last all day. More importantly, caffeine levels in beverages vary, and so does the speed and duration of its effectiveness in your body.

Find out more about how caffeine works and what it does to your body. This article might cross out those frequently asked questions on your list!

How Does Caffeine Work?

To summarize, caffeine stimulates the central nervous system. Thus, it only takes effect when it reaches your brain is that it gives you increased alertness. Thus it has to reach our brains first and from it, the brain gives signals to our muscles and endocrine system, only then we will feel the effects of caffeine.

To work its magic, it has to stimulate the heart, muscles, and the centers that control blood pressure. As a result, people feel less tired and awake if not energized after consuming it.

Moreover, caffeine is primarily broken down in the liver. Subsequently, it can stay in the blood for about 1.5 to 9.5 hours, contingent on several factors.

What is more, caffeine increases cortisol and adrenaline circulations in the body. Additionally, caffeine performs what we know as sugar-rush by halting adenosine receptors in your brain, which promote sleep.

Does Caffeine Kick in Immediately?

For most individuals, the level of caffeine in their blood kicks in for about an hour and remains there for several hours.

According to scholarly articles, once the caffeine is ingested, it could take 15 minutes to 2 hours to peak in the bloodstream.

Besides that, specific food components in the gut, mainly fibers, can slow the rate at which caffeine peaks in your blood. Likewise, the caffeine content in various products may differ.

How Long Will Caffeine Keep Me Awake?

Mainly, half of the caffeine you consume remains in your body for an estimated six hours. Aside from that, some studies claim that it can take up to 10 hours for caffeine to completely clear in the bloodstream.

Scientists explained a concept called “half-life” to describe how long a substance like caffeine lasts in the body. Simply put, this pertains to the time it accumulates for the substance to be reduced by half.

Moreover, according to the American Food and Drug Administration, caffeine has a half-life of four to six hours. This just means that half of the caffeine content of the food or beverage you consume remains in your body for up to six hours.

However, just like the speed of caffeine’s peak, there is an indefinite answer to how long caffeine can keep you awake. Again, this is because various factors affect how long your body stays stimulated by caffeine.

It’s also important to know that caffeine works differently for each person. Thus, what works for you may not work for another.

Is 200 mg of Caffeine a lot?

The average adult in the United States takes about 200 mg of caffeine per day. This is roughly equivalent to two 5 oz. cups of coffee or four 12 oz. colas. In my opinion, this is a bit much considering I prefer my caffeine in about 50-100 mg.

Based on studies conducted, they proved that caffeine consumption of 200 milligrams has no significant adverse effects in healthy people. In fact, some studies state that many people even have no concerns with consuming 400 mg per day.

But although that may be true, it is a different story for a range of factors, such as pregnancy, drug use, and sleep deprivation. For that reason, it is not recommended that pregnant women consume more than 200 mg of caffeine per day.

In conclusion, according to research, 400mg of caffeine per day or less is an appropriate dose for the general population. More importantly, the American Academy of Pediatrics recommends that kids under the age of 12 avoid consuming caffeine-containing foods or beverages.

As for adolescents aged 12 and up, the recommended caffeine consumption should be limited to no more than 100 mg per day.

How Long Does Caffeine Take to Kick in?

There really isn’t an exact number of how long it takes caffeine to kick in; however, according to surveys and interviewsmost caffeine consumers claim that they feel its effects kick in around 15-20 minutes after ingestion.

In most cases, how fast or slow caffeine kicks in is affected by certain factors, including the amount consumed and frequency of consumption. Additionally, health conditions also determine whether caffeine can immediately stimulate your body.

Although there are some instances that the caffeine levels peak around an hour later for most folks who aren’t regular caffeine users. Meanwhile, other respondents of caffeine-related studies claim that it takes approximately 5-30 minutes.

How Long Does G Fuel Last? (Answered) – REIZECLUB

Whether you’re wondering how long G Fuel will last or if it will go bad, you’re not alone. When it comes to energy drinks, G Fuel is a well-known brand that covers all types of tastes at an affordable price.

Accordingly, G Fuel is expected to do its magic within 10-15 minutes. Moreover, if you consume more than three servings, the effects on your energy and attention might last up to six hours.

Although, I don’t recommend you do this. Drinking in moderation is, of course, always advised.

To learn more about G Fuel, stick around for the rest of this article.

G Fuel Nutrition Facts

Here’s a quick breakdown of what nutrients you’ll be getting from G Fuel.

G Fuel Typical Values ​​per Standard Serving (7g)
Energy 25 calories
Fat (Of which Saturated) 0g (0g)
Carbohydrate(Of which Sugars) 5g (0g)
Sodium 79mg
Caffeine 150mg
Vitamin C 250mg
Vitamin E 15IUInternational Units)
Vitamin B3 (Niacin) 45mg
Vitamin B6 10mg
Vitamin B12 425μg
List of Vitamins and Minerals in a 7g serving of G Fuel.

With that in mind, even though G Fuel is low in calories and sugar, it still contains a significant quantity of caffeine, which may lead to caffeine overdose if used in excess.

G Fuel performs well as an energy drink intended for gamers of all kinds, with just the proper levels of caffeine and other chemicals to keep them at their peak performance, or as what the gamers call it the “zone”.

On the other hand, overdosing on G Fuel might have the opposite effect. Suppose you don’t stay abreast of how much caffeine you’re taking in. In that case, you may end up with a caffeine overdose, given that a regular serving has 150 milligrams.

Ingredients of G Fuel

To compare these products in more depth, I’ll start by giving you a list of all the ingredients included in each serving.

An overview of what each part comprises is provided below. In most cases, it consists of three main parts. For instance:

Energy Complex (1.79g):

Focus Complex (1001 mg):

Antioxidant Complex (26 mg):

  • Pomegranate Fruit Extract
  • Grape Seed Powder
  • Fruit Powders (Pineapple, Apple, Orange, Blueberry, Plum, Raspberry, Strawberry, Watermelon, Lemon, Watermelon, Lime, Melon, Sour Cherry, Papaya, Peach, Grapefruit, Pyrus Communis)

Other Ingredients:

  • Maltodextrin
  • Maleic Acid
  • Silicon Dioxide
  • Acesulfame Potassium
  • Sucralose
  • Natural And Artificial Flavors
  • Fd&c Red #40

How Long Before G FUEL Goes Bad?

G Fuel has a “best before” date of about a couple of years. Technically, its energizing capacities don’t go rotten, but moisture frequently causes the powder to stick beyond the expiry date.

As an energy drink lover like myself, I can attest to the fact that energy drinks may last for at least two years beyond their “stock” date, depending on how they were kept. Also, if stored properly in a low, cold environment, the beverage may survive for years without losing its flavor.

If an energy drink does go stale, it isn’t detrimental as much as it will begin to degrade. Initially, the drink will lose some fizz and will gradually taste bland.

Ever wondered what happens if you only drink energy beverages? You’re in for a treat, this video answers just that.

Is G FUEL Safe to Drink Every Day?

Chiefly, as long as you don’t overdo it and keep your caffeine intake in check, taking G Fuel on a daily basis is safe and even advantageous.

Despite its low-calorie count and absence of sugar, G Fuel has 150mg of caffeine in a single serving. Although, because of the caffeine content, I suggest you consume no more than two servings (14g) of G Fuel per day due to potentially adverse effects.

However, unless you’re planning a full-day activity, consuming two doses of G fuel powder a day may be unnecessary, given that a single serving provides an energy boost that lasts for up to 4 to 6 hours.

In any event, exceeding the FDA’s suggested daily limit of 400mg of caffeine is a terrible idea since it will put you over the maximum.

Hence, please keep in mind that just because you can consume more than two servings of G Fuel a day doesn’t indicate you are ought to. G Fuel should only be used in moderation, keeping your caffeine consumption controlled.

The list of G Fuel's Energy Complex, Focus Complex, and Antioxidant Complex.
This is a list of all the vitamins and minerals found in a tub of G Fuel.

How Long Does G Fuel Last?

Estimated by how many servings are taken at once and the frequency of usage, G fuel’s effects may last between four and six hours.

Between four and six hours is the FDA’s estimate of the half-life of caffeine. So if you drink a caffeinated beverage, half of the stimulant is still in your system six hours later, keeping you awake.

This is why it’s important to note that you should not go overboard on these beverages since they will lead you to have a harsh come down when you’re done with them.

However, various personal factors, such as health and metabolism, might influence how quickly G Fuel begins to work for you, making it a unique experience for each individual.

Does G FUEL Keep You Awake?

If you’re having trouble staying awake when playing video games or studying late at night, G Fuel may be the solution you’ve been looking for.

Even though G Fuel doesn’t provide you energy in the traditional sense, the caffeine it provides keeps you awake and sharp, enabling you to complete your work.

Indeed, the amount of caffeine in an energy drink is the most vital component to consider when evaluating its efficacy. So, consuming more caffeine will keep you up longer!

Still, having said that, don’t overdo it on the caffeine, and know your limits before consuming more than you can manage.

Check out my article on whether G Fuel is bad for you if you were wondering about that…

Energy Drink Alternatives to G Fuel

If you want to spice things up a bit, here are a few alternatives to G fuel that I’ll promise you will enjoy.

Game Fuel

This may come as a bit of a shock, but G Fuel and Game Fuel are two completely different goodseach with their own unique formula and packaging. In contrast to G Fuel, which is best known for its powdered energy drink collection, Game Fuel comes in a can.

Game Fuel has 90mg of caffeine per 16 fl. oz can, less than half the amount of caffeine found in other energy beverages of the same size.

Given that energy typically contains anywhere from 50 to 300mg of caffeine per 16-ounce serving, the caffeine concentration in Game Fuel is relatively modest.

As far as I’m concerned, Game Fuel hits that perfect spot between getting just the proper dose of caffeine and helping you overcome that afternoon lull.

Ghost Gamer

GHOST Gamera nootropic supplement to enhance cognitive performance, is available in the form of a tasty energy drink.

In addition to its well-known and proven components, such as citicoline and tyrosine, this product incorporates Nutrition21’s NOOLVL, a chemical substance tried on pro novel players and proved to be effective in boosting cognitive performance.

Ghost Gamer has 150 mg of natural caffeine per serving, which is considered a moderate quantity. Even though this is a low concentration compared to other potent energy drinks, it should provide you with the attention and sharpness you need throughout the day.

REIZE (10/10)

G Fuel is a great energy drink; However, I believe REIZE is superior.

The powder granules of REIZE energy drink come in a handy 4g sachet, making it easy to carry everywhere. It offers a moderate 50mg of caffeine, is sugar-free, and only has 11 calories per serving.

Additionally, the combination of taurine, ginseng, and B-vitamins in REIZE provides you with an energy surge without the subsequent sugar crash.

If you’re looking for a great deal, REIZE can be delivered to your front door for as little as $1 per drink.

Get your hands on REIZE now, and you’ll see how G Fuel has been outshined by REIZE.

Pouring water on a glass filled with ice and REZIE energy drink powder.
Unlike a tub of G Fuel, a pack of REIZE energy can fit inside your pocket. A pocketful of energy indeed!

Other Energy Drinks You Should Try:


To sum up, it takes roughly 15 minutes for G FUEL’s benefits to take effect from the time it’s consumed.

You should start with a smaller portion or a single serving of G Fuel and just increase the amount if you find it lacking in flavor or energy boost.

If this is your first time around, don’t go overboard and consume two servings in one sitting. This is a recipe for disaster, especially if you are sensitive to caffeine.

My best suggestion is to use G Fuel sensibly, limit your use to no more than one serving per day, and only use it when absolutely necessary.

How Long Does Red Bull Last? (Answered) – REIZECLUB

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?

In short, 80mg of caffeine can last for one to four hours, depending on the individual. That’s about the same caffeine content as the average cup of coffee.

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
  • Natural and artificial flavors
  • Colors

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:

Content Amount
Calorie 110
Carbohydrates 28g
Caffeine 80mg
Niacin 100% of the recommended daily intake
Vitamin B6 250% of the recommended daily intake
Vitamin B12 80% of the recommended daily intake
Pantothenic Acid 50% of the recommended daily intake
Nutritional Information of Red Bull.

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 exactly how much taurine is in a can of Red Bull, this article states that 3000mg of taurine is still safe.

Caffeine energizes you!

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’t. Drinking 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 interventionthis 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 the 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 alertness, focusand 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.

Other Notable Mentions

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.
