Caffeine pills for improved performance -

Each person will have a different tolerance level. There are some risks associated with taking caffeine, particularly at high levels and in people sensitive to the substance. Additionally, too much caffeine can overstimulate the body, causing side effects.

Some adverse effects of caffeine, especially in high doses, include :. The National Center for Complementary and Integrative Health NCCIH notes there is a link between heavy caffeine consumption and issues such as:.

Large amounts of caffeine may also cause serious issues in the heart and blood vessels, including:. Children, teenagers, and young adults should avoid taking caffeine pills. This drug may harm the developing nervous and cardiovascular systems in young people. Taking caffeine regularly and then suddenly discontinuing use may lead to temporary withdrawal symptoms, including :.

A caffeine overdose is possible in people who take very high doses of caffeine. Extremely high amounts of this drug are toxic and can even be fatal. Overdose symptoms include :. Anyone experiencing symptoms of an overdose should seek immediate medical attention.

Caffeine pills allow a person to take their preferred caffeine dose easily. People should follow the dosage instructions on each product and monitor any side effects or symptoms they experience. People sensitive to the effects of caffeine pills may need to lower their dosage or switch to a weaker product.

Do not take more than the recommended dose. Even in people with a high caffeine tolerance, other ingredients in the pills may cause adverse effects.

People should also be aware of any potential interactions between caffeine and prescription and nonprescription drugs. A review notes that varying levels of caffeine can affect the absorption and effectiveness of certain substances, such as selective serotonin reuptake inhibitors and iron-rich food or supplements.

MedlinePlus states that people should contact a healthcare professional before consuming caffeine if they take certain prescription medications, such as:. Even if product labels claim their pills derive from natural ingredients, they can still pose a risk when taken with other medications.

People should speak with a healthcare professional before using any supplements. According to the FDA, adults can generally consume up to mg of caffeine , or around 4—5 cups of coffee, per day without experiencing dangerous or negative side effects.

However, some people may be more sensitive to caffeine than others. Additionally, people who are trying to conceive, are pregnant , or are breastfeeding should contact a healthcare professional to discuss how much caffeine they can consume each day.

The FDA also warns that caffeine dietary supplements can be dangerous. Small amounts of pure or concentrated caffeine powder can lead to serious side effects and even death. For example, half a cup of highly concentrated caffeine powder contains similar amounts of caffeine to 20 cups of coffee.

One teaspoon of pure caffeine powder is equal to 28 cups of coffee. People should ensure that they carefully measure the amount of a supplement they consume and avoid pure or highly concentrated caffeine products that have the potential to cause harm.

Consuming too much caffeine can lead to serious side effects. The FDA has linked two deaths to pure and highly concentrated caffeine products in the United States. People should remember that natural or herbal caffeine alternatives are not risk-free.

They could still trigger potentially harmful drug interactions in people with health conditions or people who take prescription medications. Discuss these with a doctor before taking any caffeine supplements or alternatives.

In addition, the FDA does not regulate these products. Buyers should make sure they choose products that have gone through independent laboratory testing to verify their purity and safety.

Two potential alternatives to caffeine that can increase alertness are ginseng and maca. Ginseng is an herb that people have used for over 2, years for various reasons, including as a stimulant.

However, the NCCIH states that many studies investigating the effects of ginseng are of low quality, and more research is needed. Maca may also be beneficial for people who are sensitive to caffeine or for those who are looking for an alternative.

A study from suggests that maca may reduce tiredness. However, this research only investigated the effects of maca on people who have gone through menopause. In a animal study , maca improved physical fatigue in mice by strengthening muscle structures.

However, these results have not been replicated in humans. As an alternative to drugs, people may benefit from the following to help them feel more awake and alert:. A person can consider discussing caffeine pills with a doctor if they are intending to take these on a regular basis.

If a person develops any of the following side effects after taking caffeine pills, they should seek medical attention:. Most people can safely consume up to mg of caffeine per day. Caffeine pills may be healthier than getting caffeine from other sources, such as energy drinks, as they may not contain sugar or other added ingredients.

It is also easier to know how much caffeine a person has consumed. Supplements will list the dose per serving on the product label. However, a person should discuss taking caffeine pills with a doctor before starting. Caffeine pills can interact with medication and cause side effects.

If a person needs caffeine pills to boost their energy, they can also discuss other ways to improve fatigue with a doctor, such as exercise and drinking water, which may be healthier than taking caffeine pills. Additionally, people taking caffeine pills should limit the caffeine they consume from other sources, such as tea and coffee.

People will react differently to varying doses of caffeine. As such, the most effective caffeine pill for one person may not be effective for another. It will also depend on what effect a person would like to get from a caffeine pill. Some caffeine pills claim to aid concentration, while others aim to provide people with a boost of energy.

To find the most effective caffeine pill for them, a person should consider how high they would like each dose to be and the purpose they would like the pill to serve. Caffeine pills allow people to take measured doses of the stimulant in a simple form, which may provide energy and a boost in alertness and mental performance.

Other ingredients could help enhance the effects of caffeine or provide additional benefits to the body. However, it is vital to use caffeine wisely and follow the instructions on the label.

Before trying supplements, people should consult a doctor, particularly when taking other prescription medications. People sensitive to caffeine may want to avoid caffeine pills and try alternatives, such as drinking more water or going for a brisk walk.

It is important to note that the meta-analysis did not test the full set of relationships involving PWM variables; it focused on the postulated correlations between prototypes, willingness and intentions and thus corroborated the postulated processes of the social reactive path.

Most importantly the meta-analysis revealed that although willingness and intention are sometimes highly correlated they also act as independent predictors of risk behavior. Willingness explained an additional 4. The postulated correlations between variables in the reasoned pathway have been tested in several other PWM-related studies e.

Astonishingly, however, there is a dearth of empirical analyses of the full set of PWM variables using, e. Neuroenhancement research e. The PWM is a comprehensive psychological theory of behavior that integrates all these variables.

The PWM postulates two interacting pathways of behavioral regulation: the reasoned action path, in which attitudes and norms predict intention the most proximal predictor of behavior and the social reactive path, which integrates information from prototypes, attitudes, and norms to form another proximal predictor of behavior, i.

The PWM thus represents an integrative psychological framework for the study of NE behavior. Use of drugs for NE carries health risks Schermer et al. A third group received no information about prevalence and served as a control group condition C.

We investigated use of caffeine pills specifically. Caffeine is available in over-the-counter products and in higher doses as a prescription drug.

Our second research question was based on the assumption that university students would have some sort of subjective perception of the prevalence of NE in their peer group and that this perception would shape their thinking about NE.

We explored whether experimentally manipulating information about the prevalence of use of caffeine pills for NE amongst peers high prevalence; low prevalence; no prevalence information would influence the behavioral determinants specified in the PWM attitude, subjective norm, user prototype, willingness, and intention and the associations between these variables and willingness or intention to engage in the target behavior.

This study was conducted online as a factorial survey experiment Jasso, The Questback EFS The questionnaire was presented in German i. The access link was distributed via Facebook and email thus creating a convenience sample drawn from the target population, university students in Germany.

Data collection started in March and ended 3 weeks later in April The study was carried out in accordance with the recommendations of the ethical committee of the University of Potsdam February All participants gave written, informed consent in accordance with the Declaration of Helsinki.

Four hundred and thirty-six university students clicked on the link giving access to our survey. Of these Forty-nine students did not consent to having their data saved and analyzed on the last page, so the responses of participants One year-old participant did not provide information about gender.

When they clicked through to the second page of the online questionnaire participants were randomly assigned to one of the three experimental conditions. Participants in condition A fivefold overestimation of prevalence; Franke et al.

The descriptive facet of this PWM variable was captured using three statements see Hammer and Vogel, to which participants responded using a six-point, i. Higher values represented a more positive attitude toward use of caffeine pills for NE. The mean score from these five items was used for statistical analyses.

Participants were asked to imagine what a typical user of caffeine pills — perhaps a fellow student from their university — might be like see Gibbons et al. Participants were asked to read two hypothetical scenarios and rate their willingness to use NE in each see Gibbons et al.

You have the option of taking caffeine pills to dispel your fatigue and thus revise more effectively. Participants were asked to provide their age and gender, and state whether they were currently enrolled as a university student.

Participants were also asked whether they thought there was anything suspicious, wrong, or strange about the questionnaire, and in particular if they thought they had been manipulated by the ways in which we gave or asked for information earlier in the questionnaire.

The last page of the questionnaire provided full information about the goals and procedure for the study. This included a statement of the actual estimated prevalence of use of caffeine pills for NE among university students i.

Participants had to tick response boxes to indicate that they had read and understood this information and consented to the confidential storage and analysis of their data for scientific use by the Division of Sport and Exercise Psychology of the University of Potsdam. SPSS Structural equation modeling SEM with Amos A SEM multigroup moderation approach Byrne, was used to investigate experimentally induced alterations in the relative predictive power of PWM predictors of willingness and intention Lowry and Gaskin, These tests were carried out with a program created by Gaskin which calculates z -scores based on critical ratio tests of the multigroup model and unstandardized estimates.

Information from the second question of the manipulation check was evaluated qualitatively. Previous research suggests that male and female students may differ in their use of caffeine for NE Franke et al. We therefore concluded that in spite of the randomization error under-representation of men in condition B the randomization process was successful overall.

The group mean responses to the question about what percentage of university students in Germany used caffeine pills for NE on at least one occasion were as follows: group A fivefold overestimate of prevalence, i.

This finding is illustrated in Figure 1. Thirty-one participants Descriptive statistics for all variables are summarized in Table 1. The low variance inflation factor of 1. The structural model with regression weights for relationships between variables bootstrapped CI s in Table 2 and determination coefficients for variables is displayed in Figure 2A.

TABLE 2. FIGURE 2. The Prototype Willingness Model Gibbons et al. for paths and the illustration of experimental effects B. We therefore concluded that provision of experimentally manipulated information about peer behavior did not produce group mean differences in any of the investigated variables.

This means that in our sample provision of information about prevalence of use of caffeine pills for NE decreased the predictive value of attitude to use of caffeine for NE on willingness to do so.

Testing predictions derived from a theory of behavior minimizes the risk of reporting random effects and overestimating relationships; it is thus a suitable strategy for uncovering the psychological mechanisms underlying behavior and behavior change Zelli et al.

On the basis of this result and previous findings on the effects of peer pressure Sattler et al. Interestingly, in this investigation attitude was a much weaker predictor of intention than in other investigations of problematic consumption behavior e.

The most likely explanation for this is that we chose to measure a very specific intention, i. In particular, we recommend research into the conceptual relationship between willingness and intention empirical data from many studies based on the PWM suggest that the two constructs are fairly highly correlated, c.

Todd et al. We think that willingness to engage in a given behavior may be much more sensitive to changes in motivational predictors e. A fundamental assumption of the PWM is that willingness is the basis of socially reactive, i.

Structural equation modeling modeling enabled us to estimate correlations between the PWM variable past behavior and the residual variance in willingness and intention with respect to the relevant behavior. These unidentified variables have a considerable impact on willingness and intention to use specific neuroenhancers and perhaps NE more generally.

Candidates for these thus far unidentified variables might be found in the psychological roots of NE behavior and perhaps in the goals at which NE is directed. The PWM variable past behavior was linked to social norm and attitude but had almost no relationship with user prototype.

In the terminology of the PWM the basis for socially reactive use of caffeine pills to improve academic performance seems to be the strong influence of attitude on willingness; user prototype appears to play little role in socially reactive NE in this instance.

This may be due to our choice of example neuroenhancer, namely caffeine pills. If we assume that university students are better educated than the general population we might expect them to be more resistant to social influences and generally less prone to unplanned, socially reactive behavior and hence that user prototype would be a stronger predictor of NE behavior in other samples and in relation to other substances.

We suggest that receiving new information about peer prevalence might weaken the association between attitude to a given behavior and willingness to engage in it. This finding reinforces our main contention, shared by other authors Wolff and Brand, ; Wolff et al. The limitations of this research should be acknowledged.

First of all, psychological theories such as the PWM are intended to predict behavior. We have neither predicted a temporal relationship e. We experimentally manipulated one variable information about prevalence and were thus able to make causal inferences related to this manipulation providing information about prevalence reduced the influence of attitude to NE on willingness to engage in it.

We are, however, unable to draw conclusions about the validity of theoretical assumptions about the causal relationships between other variables e. Longitudinal studies are needed to draw conclusions about the consequences of changes in motivational determinants.

Another limitation of our study is that our analyses were based on data from an ad hoc sample of university students which may not have been representative of the population. Although, we are optimistic that our findings are valid further studies are needed to corroborate our findings and interpretation.

We hope that future research will be theoretically informed, seeking to address research questions derived from and relevant to psychological theory.

By taking this kind of approach we have shown that information about the prevalence of a behavior amongst peers — in this case use of NE to improve academic performance — might have a deterrent effect via attitude to NE and willingness to engage in NE. The approach described in this study might be particularly useful for the designers of public health campaigns.
