Everything you need to know about caffeine

Caffeine is a compound. It is considered a drug, although it is freely available and unregulated. Caffeine occurs naturally in many plants, including coffee and cocoa beans, as well as tea leaves. It is also used in over-the-counter (OTC) and prescription drugs.

While the origins of caffeine’s medicinal use are not fully understood, research suggests that the practice of drinking coffee and tea on a regular basis is relatively recent from a historical perspective. The use of coffee became widespread in the 15th and 16th centuries and in Europe in the 18th and 19th centuries.

As for tea, it became popular during the Ming Dynasty in China (14th to 17th centuries) and in England in the 18th century.

The medicinal use of caffeine predates its modern use as a stimulant. This article will discuss what caffeine is, its potential benefits, side effects, and safety concerns.

What is caffeine?

In its most basic form, caffeine is a chemical compound.Its scientific name is 1,3,7-Trimethylpurine-2,6-dione. Caffeine occurs naturally in more than 60 plants. It is often added to other substances, such as medicines, beverages, and foods (such as energy drinks and snacks).

What does caffeine do

Caffeine is a stimulant. It acts on the central nervous system. Its role as a stimulant is why you feel alert and energized when you consume caffeine.

Although caffeine is probably most commonly used to increase alertness, it does have other effects on the body. These effects are often less than ideal and serve as a reminder that caffeine is a drug.

In addition to increasing alertness, caffeine:

  • Being a diuretic, this means that it makes your body excrete more water and salt; this is why you often need to urinate when drinking caffeinated beverages like coffee and tea.
  • Causes more acid to be released in the stomach, which can give you heartburn.
  • Increase your blood pressure.

Dosing recommendations are tricky because some people are more sensitive to caffeine than others. Also, some people metabolize caffeine faster, which means they may feel the effects of caffeine sooner, so it doesn’t take much to get started. In general, the FDA recommends no more than 400 mg of caffeine per day, which is roughly equivalent to four out of five cups of coffee.

It’s important to remember that small doses of caffeine can still contain high concentrations. For example, one teaspoon of pure caffeine contains the same amount as 28 cups of coffee; this can be toxic. Pure and highly concentrated caffeine products are a health risk.
