Caffeine is America’s most popular drug, as about 90 percent of the public consumes caffeine in some form, every day. For example, about 54 percent of adults drink coffee daily.

What is Caffeine?

Caffeine is an addictive stimulant (a drug that increases physiological and nervous system activity) that is made from either natural or commercial sources. Natural sources include around 60 plant sources like coffee beans, cacao seeds, tea leaves, kola nuts, and more. Commercial sources include energy shots/drinks, soft drinks, and caffeinated alcoholic beverages.

How Much is Too Much?

Moderate amounts of caffeine are not harmful, but it affects everyone differently. According to dietary guidelines, it is okay to drink three to five cups of coffee a day, but stay away from adding cream, milk, or sugar if you do this. The numbers also depend on your weight, gender, and how sensitive you are to caffeine. Since coffee is the most caffeinated and most popular drink in the United States, it is the most studied substance.

People with certain illnesses, such as heart disease or anxiety problems, should try to avoid too much caffeine, because it might cause complications or worsen their condition. Caffeine overdose is dangerous, so be sure to monitor your caffeine intake and find out how much you’re drinking daily.

How to Get Energy Without Caffeine

If you want an alternative to your caffeinated drink of choice, try some of these options for a natural source of energy.

  • Make sure you’re drinking enough water. Dehydration can cause fatigue or a lack of energy, so adding more water to your diet can help to fuel your day.
  • Maintain a healthy, balanced diet. Follow the plate method to make sure you get enough protein, which helps improve concentration and can improve energy levels.
  • Take B12 vitamins. About 40% of the population is deficient in B12. This vitamin can significantly improve your energy and mental clarity, and can even help you sleep better.

Caffeine can be healthy, but too much of a good thing can sometimes cause more harm than good. Be sure to keep your caffeine levels in check to prevent the common symptoms, such as sleeplessness.
