The following sections explore the benefits – such as reduced depression, improved metabolic processes, increased exercise performance, reduced headaches, increased alertness, improved cognitive function, reduced pain, increased focus, and reduced incidences of constipation – and side effects – such as increased anxiety, cardiovascular issues, increased headaches, gastrointestinal upset or issues, and more – of caffeine supplement consumption.Cognitive levels of learning benefits

2Caffeine supplements may boost metabolism. A 2007 study involved 31 male and female subjects and caffeine’s effect on their metabolic function.Cognitive levels of learning it was found that caffeine increased energy expenditure in the subjects in the study by almost 5%. However, researchers also noted that weight maintenance and weight loss should also involve a healthy diet and physical activity ( 3 ).Cognitive levels of learning

An older study also showed similar results. 9 athletes participated in the study and performed cycling until exhaustion once without taking caffeine and once after caffeine consumption.Cognitive levels of learning it was shown by biological markers that lipid metabolism was greater in the caffeine trial. The athletes also performed better in the caffeine-induced trial ( 5 ).Cognitive levels of learning

4 caffeine supplements and consumption may reduce headaches. One study determined the effectiveness of combining acetaminophen, aspirin, and caffeine when it came to relieving migraine headache pain.Cognitive levels of learning pain intensity was reduced in participants 1-6 hours after the combined consumption. Researchers concluded that this combination may aid in reducing headaches and serve as a treatment for migraines ( 7 ).Cognitive levels of learning

An older 1993 study went even further, exploring caffeine and its effects on sleep-deprived individuals. 50 males participated in the study. After 49 hours without sleep, the subjects received caffeine.Cognitive levels of learning it was found that the caffeine reduced sleep deprivation changes, including fatigue, vigor, and confusion, even bringing them back to normal resting levels.Cognitive levels of learning researchers concluded that caffeine had the potential to increase alertness and even mood in sleep-deprived individuals ( 10 ).

The cognitive tests performed in the study included scanning visual vigilance, 4-choice visual reaction time, a matching-to-sample working memory task, and a repeated acquisition test of motor learning and memory.Cognitive levels of learning in the initial stages of the study, researchers saw participants mood and performance decline with sleep deprivation. Yet, when 200-300 mg of caffeine was supplemented, participants had improved visual vigilance, reaction time, self-reported fatigue, and alertness.Cognitive levels of learning

A 2008 study compared 50 mg of caffeine with or without 100g of L-theanine on cognitive function and mood. Participants’ performance measurements were taken at baseline, 60 minutes, and 90 minutes.Cognitive levels of learning alertness and accuracy in attention-switching tasks improved in the caffeine group, while it also improved in the caffeine and L-theanine group, along with a reduced susceptibility to distraction ( 14 ).Cognitive levels of learning

7Caffeine supplements may increase and improve memory function and processes. One study involved 95 young and healthy adults. 0, 200, and 400 mg of caffeine were given to the participants.Cognitive levels of learning researchers found that the 200 mg group had better performance on some tasks. Caffeine also decreased boredom and increased participants’ moods.Cognitive levels of learning they concluded that moderate to high caffeine consumption was associated with better recall ( 16 ).

A 2008 study also explored the effects of caffeine consumption on the verbal, motor, and perceptual memory.Cognitive levels of learning A verbal task, recall, and recognition for words, a word list, and a finger tapping task were used as measurements. It was found that caffeine greatly decreased motor learning ability, but it improved memory retention when it came to recall and recognition of words ( 18 ).Cognitive levels of learning

A 2008 study also showed similar results. Researchers explored the use of caffeine and aspirin on pain perception and pain levels. Aspirin, caffeine, or a placebo were consumed by participants prior to exercise.Cognitive levels of learning the caffeine group had significantly more reps and sets. It was concluded by researchers that caffeine not only improved performance, but also decreased pain perception and fatigue ( 21 ).Cognitive levels of learning

Another study also supported these claims. 99 participants were involved in this specific study by answering questionnaires. 63% of the women claimed that coffee (caffeine) increased the desire to defecate.Cognitive levels of learning further, researchers found drinking coffee stimulated a motor response in the distal colon in healthy individuals ( 29 ). Side effects

Can caffeine kill you?Cognitive levels of learning having a few cups of coffee or other caffeinated drinks a day is considered perfectly safe. But drinking too much or lots in a short space of time is risky.Cognitive levels of learning you can overdose on caffeine and it is possible to die if you ingest too much – however, the scenario is very, very unlikely. Up to 400mg of caffeine per day appears to be safe for most healthy adults.Cognitive levels of learning

The recommended safe dosage of caffeine is no more than 400 milligrams per day. Most caffeine pills contain about 100-200 milligrams of caffeine, which equates to that of one cup of coffee.Cognitive levels of learning always make sure to read the labels and instructions on the packaging thoroughly before consuming any new supplement. Overdosing on caffeine pills is entirely possible, as outlined above in the side effects section of this article.Cognitive levels of learning

I n turn, this may help with weight loss or weight maintenance. However, researchers do caution that a healthy lifestyle is essential for maintaining a healthy weight.Cognitive levels of learning other studies have proven caffeine to improve exercise performance, reduce headaches (yet, in some incidences, it may increase headaches, especially at possibly higher dosages), improve alertness and focus, and increase memory retention and cognitive function.Cognitive levels of learning in addition, caffeine may stimulate sections of the gastrointestinal tract, helping to relieve constipation.

Higher doses of 600 mg or more are often associated with increased side effects.Cognitive levels of learning side effects are also more likely to occur in individuals that do not regularly consume caffeine. It’s also recommended that those with anxiety disorders avoid or limit their caffeine intake, as this may make such conditions worse.Cognitive levels of learning individuals with gastrointestinal issues or who are prone to acid reflux may also choose to avoid caffeine consumption, since such individuals may have a higher sensitivity to associated side effects.Cognitive levels of learning
