According to a report by PharmEasy, roughly 80% of adults in the US take in caffeine every day. But what path does the invigorating drink take from a small grain to a fragrant mug?

This exciting journey begins when the coffee beans just begin their journey on the plantations under the bright sun of Brazil, Colombia, etc. The beans are carefully harvested, taking into account their ripeness and quality, before they move on to the next stage. After that, they go through a processing process that includes drying, removing the outer shells and the magic of roasting begins.

When choosing a brewing method, consider taste preferences, time, and convenience.

Caffeine, as a psychoactive substance, has a range of impacts on the neurological system, stimulating wakefulness and reducing fatigue.

It is also able to increase the production of gastric juice and cause a diuretic effect, stimulating urination. In addition, caffeine can affect liver function, which affects the processing of medications and other substances. Moderate intake of caffeine is usually safe, but it may cause stomach discomfort in some people.

Additionally, it can narrow blood vessels, thereby alleviating skin swelling and inflammation. Several studies imply that caffeine may foster hair growth and mitigate hair loss.

It is important to consult your doctor or pharmacist about any changes in your caffeine intake. It is also important to find other alternative beverages to mitigate the potential negative effects of caffeine-drug interactions.

The Body’s Response to Caffeine Overdose

In some cases, more serious complications may occur, such as seizures or cardiac arrest. The maximum daily dose of caffeine for most adults is 400 mg. However, for some people, even lower doses may cause negative side effects. Some people can consume up to 1000 mg of caffeine which is too much for whole-body health.
