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.
