Top 25+ Caffeine Health Benefits


Caffeine is the most widely used substance on the planet. Are there health benefits from caffeine or is most of the world just poisoning themselves?

We’ve dug through our archives and put together a list of some of the possible caffeine health benefits according to different studies that have been conducted over the years.

25 Possible Caffeine Health Benefits

  1. In Japan, researchers have shown that caffeine increases memory. Also, a newer study out of Johns Hopkins University showed that a 200mg caffeine pill helped boost memory consolidation.
  2. Caffeine mixed with carbs replenishes muscle glycogen concentrations faster after exercise.
  3. Caffeine detoxes the liver and cleanses the colon when taken as a caffeine enema.
  4. Caffeine helps keep you alert while driving during periods of sleep restriction. Here’s the research
  5. Caffeine can stimulate hair growth on balding men and women.
  6. Caffeine relieves post-workout muscle pain by up to 48%.
  7. Caffeine relieves pain associated with sleep loss better than analgesics.  The study.
  8. Caffeine may protect against Parkinson’s disease. Research shows that those who consume coffee are at less risk of developing Parkison’s disease and it even reduces the risk of those genetically more likely to develop the condition. Here’s the study.
  9. Caffeine helps ward off Alzheimer’s.
  10. Caffeine increases stamina during exercise.
  11. Caffeine through coffee protects against eyelid spasm.
  12. Caffeine may protect against Cataracts.
  13. Caffeine may prevent skin cancer. A new study out of Rutgers University found that caffeine prevented skin cancer in hairless mice. Another study showed that caffeinated coffee drinkers have less risk of developing melanoma.
  14. People who consume caffeine have a lower risk of suicide. Src.
  15. Caffeine may reduce fatty liver in those with non-alcohol related fatty liver disease. This study comes out of Duke University.
  16. Caffeine is shown to reduce liver fibrosis risk in patients with hepatitis C. As little as 100 mg per day is believed to have protective benefits. Src.
  17. Caffeine consuming men showed increased semen volume and significantly less sperm DNA fragmentation than non-caffeine consuming men. Src.
  18. Men who consume 250-375mg of caffeine per day have a much lower risk of developing ED (erectile dysfunction). Reduced risk was even observed among men consuming as little as 85mg of caffeine daily. This research was conducted by The University of Texas Medical School. Src.
  19. Caffeine may prevent ringing in the ears (tinnitus) in women: A study recently published in The American Journal of Medicine followed a group of 65,085 nurses since 1991. The women who consumed the most caffeine had the lowest incidences of tinnitus reported. Src.
  20. Caffeine Reduces Kidney Stone Risk. In a large 217,883 person study, those that consumed caffeine from any source had less kidney stone formation than those that did not consume caffeine. The researchers believe that this is because caffeine makes urine more dilute. Src. Caffeine has also been shown to reduce the mortality rate in those with chronic kidney disease. Caffeine appears to have a protective effect on the progression of the disease. Here’s the study.
  21. Caffeine improves reaction time and logical reasoning during times when sleep isn’t possible or restricted. See the study here.
  22. Caffeine helps those with asthma. A study published in the U.S. National Library of Medicine concluded that caffeine seems to open airways and help asthmatics breathe easier similarly to theophylline a drug currently used and one that’s a close cousin to caffeine. The study.
  23. Reduces driver error: A recent study conducted by the Australian Department of Defence found that caffeine consumption improves driving performance and reduces driver error. Caffeinated gum was used in the study on soldiers that had been sleep-deprived for 50 hours.
  24. Caffeine may prevent weight gain: Research out of Germany showed that weight loss study participants who drank 2-4 cups of caffeinated coffee a day were more likely to be successful at keeping the weight off than those who did not consume caffeine. The study.
  25. Caffeine reduces chronic inflammation. Researchers from Stanford University found that caffeine blocks the expression of a gene responsible for low-grade chronic inflammation as we age. This inflammation eventually leads to high blood pressure, hardening of the arteries, and heart disease. Caffeine seems to help reduce this age-related inflammation in those that are regular consumers of the drug.

There can be negative health consequences from consuming too much caffeine, so don’t go too crazy.

Also, some of the benefits of caffeine have only been researched within the context of caffeinated coffee.

Here are some further health benefits when the caffeine is consumed via coffee.

It is also interesting that these benefits didn’t carry over to those that drank decaffeinated coffee.

Caffeinated Coffee Health Benefits

  1. Caffeinated coffee cuts mouth and throat cancer risk by 50%.
  2. Coffee can reduce the risk of stroke as much as 22%.
  3. Shown to reduce the risk of several types of cancer.
  4. Heart rhythm disturbance hospitalizations decrease with coffee drinkers.
  5. Coffee decreases the risk of type 2 diabetes.
  6. Caffeinated Coffee may help with weight loss. Research out of Melbourne, Australia found that study participants reported decreased appetite when drinking regular coffee as opposed to decaf or caffeine tablets as part of an ongoing study.
  7. People who drink at least 4 coffees or teas have lower blood pressure according to a new study out of Paris. Tea drinkers had the most blood pressure benefit, while coffee drinkers had just slightly less.
  8. Research out of Greece shows that Greek boiled coffee may increase longevity and heart health.
  9. Those who drink coffee after a heart attack are less likely to die from the incident. Research shows that heart attack victims who consume more than 2 cups of coffee daily have the least risk of mortality from the heart attack.

While this list might seem like a green light for caffeine consumption, it does come with a few caveats. In most cases, the caffeine health benefits were realized by those who consumed moderate coffee/caffeine amounts. Also in some of the studies above, the caffeine was concentrated and applied directly to the body area being researched, i.e. cataracts and baldness etc.. Therefore, dietary caffeine would not produce the same results.

Recently the British Medical Journal published a study that reviewed 201 studies concerning coffee and caffeine. The researchers concluded that based on all evidence to date, the health benefits of consuming coffee outweigh any risk involved.

We can conclude that caffeine consumed via natural sources is probably the best since many of the health benefits of caffeine are probably largely due to the high antioxidant levels found in regular coffee and tea.

    guards against Parkinson’s however it will give you the “jitters” if you intake too much talk about irony huh?

  • Tien Duong

    I think claudia means the peer-reviewed articles that the information is based off of. I’m curious to the primary sources too. Can you link them please?

  • Ted

    The peer reviewed studies are linked too next to or within each benefit. In some cases they point to internal links to some of our more robust pages on the subject but those pages contain links to the studies.


    i think an optimum consumption of caffeine per day, say a cup is beneficial to health especially in decreasing CVS diseases.

  • If you want your daily caffeine fix without the (some say) unpleasant after-odor of coffee, you can get it from Sprayable Energy – the revolutionary new topical caffeine spray from Sprayable Inc. Read more here –

    “Men who consume 250-375mg of caffeine per day have a much lower risk of developing ED.”
    Consume that all at once or can be on different times of the day?

  • Ted

    The study just looked at general caffeine consumption habits and then compared it to non-caffeine consumers

  • my name is jeff

    wait, are the effects of caffeine different if you intake it from coffee or is it the same as intaking it from anything else.

  • Ted

    In some cases, yes. If you are consuming caffeine in products that have a lot of sugar or preservatives then those other ingredients would have a negative effect on health.

  • Faizan Khuram

    caffiene used in Cold Drink name Sting ” is good to drink it regularly or harmful????

  • bolvark

    The effects of the caffeine would be the same.
    BUT the effects of the non caffeine components are quite different due to being different components.

  • bolvark

    basically its saying if your options are
    A: driving with no sleep
    B: driving with no sleep and caffeine
    go with option B

  • bolvark

    Increase in the time required to become pregnant
    0.83 @ 300-700mg/day, 0.65 at >700 (M or F!)
    since when did males get bad pregnant?
    just saying this is worded pretty
    also what unit of time are we talking day months weeks years?
    and im pretty sure thats with a set rate of making out?
    cause i think a better way to increase fertillity might be to roll the dice more?

  • bolvark

    actually most of the page on here are about the negatives and to be cautious
    in all its pretty balanced.

  • bolvark

    Considering how notoriously unreliable ADHD meds are and how sever and common their side effects can be i can see using caffeine as an alternative.
    Caffeine has been know to increase focus.
    The hyperactivity often doesnt have to do with excess energy but with the inability to focus on what other want them to focus on, which creates the impression of both excess energy and last of focus.
    Thu tbh adhd has become a sort of cesspit catch all of child mental diagnoses.

  • bolvark

    would absorbing caffine in ones rectum, much akin to absorbing alcohol in the same manner, help with cancer in that area?


    Assuming you actually might have meant what you said . . . suffice it to say I’m laughing at you and not with you.

  • Judith

    Can’t believe no one replied that caffeine is put in medicine to treat headaches from aspirin to several prescriptions. Constricts the blood vessels in the brain. Often headache is caused by their expansion. (Or it’s the opposite, caffeine expands restricted blood vessels. I can never remember which!!) Whichever way it goes a cup of coffee with your aspirin has been known to avoid a migraine onset.
