Caffeine is a popular study and exam-prep substance. When used properly, it can aid performance. Further, there are many substances that contain caffeine and sustain unique effects compared to caffeinated coffee or tea.

It is no secret that caffeine helps you study. In fact, it is used as the number one “smart drug” by students everywhere. It is also a reliable standby for many workers to maintain focus and increase productivity during shifts.

Caffeine exists in the category of drugs known as “stimulants.” Unlike stronger substances in the same class, such as amphetamines, caffeine is not heavily regulated. Caffeine affects both your brain and body. When used in moderation, these outcomes support a busy, modern lifestyle. However, high usage over a long period of time can result in adverse side effects.


Studying Energy Drinks

Most people source their caffeine from coffee, pills, or tea. Energy drinks are also a popular method of consumption. Many experts suggest that regular daily use of caffeine is not harmful - 3-4 cups of coffee or tea a day is perfectly fine.

Further, it’s important to realise that everyone reacts uniquely to the drug. That is why it is essential to check the labels of products containing especially high concentrations of caffeine, such as energy drinks. Many of these beverages contain multiple servings of caffeine, which can be overwhelming for those with a low tolerance.

People usually ingest caffeine shortly before they need a mental energy boost. Effects kick in within a short window of time – between 10-45 minutes. Concentrating on mental tasks becomes increasingly easier during this period. The productive boost of caffeine will linger for different periods of time, depending on the amount consumed, as well as factors like consumer body weight, tolerance and more.

Just remember that caffeine does not work well for everyone. Additionally, some individuals find particular manifestations of the substance to be more suitable than others.


How And Why Caffeine Works

Caffeine is a bitter, white crystalline alkaloid which acts as a psychoactive stimulant on the brain. Although studies are yet inconclusive, there is empirical evidence to support caffeine’s improvement on concentration and memory over acute periods. Conversely, there are aspects of caffeine suspected to actually short-circuit short-term memory processes.

The most conclusive data so far suggests that caffeine consumption has the most positive impact on working and long-term memory. However, these data are also contingent on age and ability level. The positive stimulating effects of caffeine seem to provide the most benefits for individuals between the ages of 26-64. The average tolerated positive dose is around 300mg per day.

In addition, the time of day caffeine is consumed also impacts its outcomes on the body. When ingested earlier in the day, it sustains dramatically more positive effects than when consumed in the evening. 


Ingesting Caffeine Before Bed

Caffeine’s stimulant properties result in alterations in brain chemistry. Over time, the substance can be quite addictive. Regular users obtain less significant physiological impacts over time by consuming consistent dosages.

The adverse effects associated with caffeine consumption include increased heart rate and sweating of the palms. Ingesting high levels of caffeine during the day can also impact your ability to sleep. In fact, daytime exhaustion is an indication that your caffeine consumption is likely too high.


Brain Needs Time To Relax And Recharge

Many people use caffeine as a tool during school or work to increase their focus on tasks at hand. The best way to get the most from this stimulant is to ingest a regular serving just before beginning a study session. Between 10-15 minutes is the minimum suggested time. Once this stage has been passed, you will notice that concentrating becomes progressively easier.

Using caffeine after studying, however, is not recommended. After poring over books or documents, your brain needs time to relax and recharge. Caffeine is not an ideal substance for recovery of this sort. Instead, try drinking non-caffeinated tea, exercising, or taking a short nap.


Apart from studying, some people use caffeine during exams as an effective method to bolster performance. Caffeine used in this setting can indeed help you complete tasks with greater focus and precision.

Caffeine is a substance where too much of a good thing can have negative results. Ingesting too many cups of coffee, for instance, may render you shaky, restless and in no shape to take a test.

Relying on caffeine as a backup for lack of adequate preparation is never a good idea. Furthermore, relying on it to keep you awake for your overnight cram session could have exhausting results in the A.M.

Bottom line? Caffeine can be a great aid during both prep and test time. However, it is not a panacea for preparation.


Some people just don’t like coffee, or find that it’s caffeine levels aren’t suitable to them. Luckily, there are plenty of other products available containing varying levels of caffeine. Some report that alternative formulas of caffeine sustain less severe side effects. As research in the area mounts, more all-natural caffeine supplements are becoming popular among the health-conscious. Below, we break down some of the best formulations currently on the market.



Brain-E capsules are guaranteed to crank up cerebral activity for hours. Made from a mixture of choline, white willow bark extract and caffeine, these pills are dynamite in small packages. Dosage is 1-2 capsules. Take 45 minutes before you need to concentrate.


Kola Nut

Kola nuts have long been used in traditional African cultures for ceremonial purposes and as an aphrodisiac. Europeans began to cultivate kola plantations in the mid 1600s. As a natural source of caffeine, these nuts are used to heighten vigilance, treat fever and aid with morning sickness. With no negative side effects, this is a reliable source of energy for the conscious consumer. And yes, kola nuts were even a part of the original recipe for Coca Cola.


Yerba Mate

Yerba mate is a traditional South American brew that is used to stimulate the brain and body. Usually consumed as a beverage in a mate, this tea-like beverage is packed with vitamins. Originating from a tree most commonly found in South America, the Guarani tribes historically used the drug to improve mood, and curb appetite.



Guarana is a natural substance made from the seeds of an Amazonian vine. Traditional Indian tribes used guarana as a hunting aid and considered it a gift from the gods. It is also highly potent with three times more caffeine than coffee. Consumers rely on it today for its potency and because it doesn't cause the jitters.
