Caffeine is a natural stimulant found in coffee, tea, and also many nutritional supplements. There is robust scientific evidence demonstrating that caffeine ingestion serves as effective ergogenic acid for aerobic and anaerobic exercise performance.

Caffeine ingested orally is quickly absorbed into the bloodstream and peaks within 30 to 60 minutes. Caffeine mechanistically affects the central nervous system, primarily by antagonism of adenosine receptors, which results in enhanced mood, reduced perception of pain, increased attention, energy, alterness, and mental performance.

At the skeletal muscle level, caffeine ingestion promotes enhanced sodium/potassium pump activity, greater calcium release from the sarcoplasmic reticulum, and increased fat oxidation/glycogen sparing. That, really helpful to reduce body fat with proper diet and exercise.

Overall, it has been recommended that a dosage of ~3 to 6 mg/kg of body weight of caffeine ingested 30 to 60 minutes prior to exercise will increase work capacity, time to exhaustion, and reduced perceived effort during endurance exercise.

Benefits of Caffeine Tablets

Caffeine is a highly popular stimulant. A 2014 study estimates that 85% of the United States population consumes at least one caffeinated beverage daily. Popular forms include coffee, tea, cola, or other soft drinks.

Caffeine may be a useful substance as a fast-working natural stimulant. A 2019 study notes that this drug’s most well-known benefits include improved mood, physical performance, and brain function.

  • increase energy
  • increase alertness, focus, and attention
  • reduce feelings of fatigue or sleepiness
  • reduce headaches
  • reduce perceptions of pain and fatigue
  • boost metabolism
  • improve memory

Importantly, these effects are temporary and only last as long as the caffeine remains in the body.

The Food and Drug Administration (FDA) notes that caffeine consumption of up to 400 milligrams (mg) a day is generally not associated with negative effects in healthy adults.

However, some people are more sensitive to caffeine than others, and each individual will have a different tolerance level.

Risks and side effects

Caffeine pills cause no side effects when taken as directed, which means caffeine pills are as safe as any other supplement.

  • Restlessness and shakiness
  • Insomnia
  • Headaches
  • Dizziness
  • Fast heart rate

How long will caffeine stay in my system?

Caffeine will stay in your system for as long as a few hours, but the exact amount will depend on how much caffeine you took.

If you stick to the script and take only as directed, the caffeine should clear your system in 4 or 5 hours. If you overdid it, you could be in for a long sleepless night.


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.

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 medicines.

People sensitive to caffeine may want to avoid caffeine pills and try alternatives, such as drinking more water or going for a brisk walk.
