How long does it take to digest coffee? (3 factors)

In this brief guide, we will answer the question,’ How long does it take to digest coffee?’. Coffee digestion is a common concern for frequent consumers. This owes to the high acidic and caffeine content in the beverage. We will consider the variable factors that impact the digestion of coffee in the human body.

How long does it take to digest coffee?

Coffee is known and consumed for its stimulating properties. Besides caffeine, it has Chlorogenic acid, Quinic acid, and antioxidants. Coffee is consumed worldwide as an early morning beverage. 

Caffeine has an average half-life of 5 hours; for half of the uptaken caffeine to metabolize, it takes about 5 hours.

Let us discuss the amount of caffeine for somebody who consumed a cup of coffee. One cup holds 95 mg of caffeine, of which 47.5 mg of caffeine would be left, in a person’s body in five hours.

The optimum level of caffeine presence starts after fifteen and lasts till 45 minutes of consumption.

According to a source, 200 mg of caffeine is 99 % absorbed in 42- 39 minutes into the bloodstream.

The effect of caffeine can take 10 hours to flush out of the body.

In 45 minutes, 99% of all the caffeine is absorbed into the bloodstream.

However, some effect of consumption lasts for about a day.

Caffeine can have a lasting impact on bodily functions even after a day has passed. This fact especially holds for people with caffeine sensitivity. 

Coffee is an acidic beverage that is heavy on the stomach. Acidic foods can cause Digestive problems like ulcers and heartburn.

The effect and the rate of absorption depend on the individual as well. The body mass, the sensitivity to caffeine, dosage, and age; contribute to and impact the digestion process.

Coffee with ingredients

There are other ingredients that you may or may not choose to add to your coffee; sugar, cream, milk e.t.c.

The digestion of coffee is also faster if; consumed without milk or sugar.

When coffee is mixed with milk, the fermentation of coffee is retarded. 

The coffee and milk interact with each other and, in turn, affect the digestion in the body. The milk is hard to digest when it reacts with the astringence of the coffee.

A  dominant compound in coffee is called careine. Careine is released into the stomach and attacks the lining. It has the same effect that alkali does on the stomach membrane.

Even though coffee is supposed to increase metabolism, the additional ingredients can cause the digestion of coffee itself longer. If you take sugar or milk along with coffee, it can cause more harm than good to you. 

How does coffee digest?

When we drink coffee, it goes through our digestive system to metabolize it. The absorbable compounds enter the bloodstream, which then travels to multiple organs of the body; e.g., the brain. The metabolites then enter the liver to metabolize. 

The liver then follows multi-step processes to get rid of the coffee from the system. In subsequent procedures, the products become more and more water-soluble to allow for excretion to occur. 

The liver detoxification process occurs in two steps;

the first phase relies on B vitamins; the second phase on amino acids. 

These two phases together make the digestion of coffee possible, however subjective. Your diet and overall well-being determine how your liver responds to the caffeine detoxification process. The two phases must be balanced, to digest coffee in a healthy way.

The size of caffeine dose, interaction with other drugs also impact caffeine absorption.

The half-life of caffeine in pregnant women is around 8 hours. 

Hormonal Birth Control also slows down the effect of caffeine metabolism.

Regular smokers have a shorter half-life; 3 hours.

Certain physiological factors come into play when it comes to the digestion of coffee; such as the use of oral contraceptives, smoking, and pregnancy. The metabolism is also subjective to tolerance and sensitivity to the coffee compounds.

Pregnant women experience a slower metabolization of caffeine, which means that it stays longer in the body. The slow metabolization of caffeine is usually accompanied by symptoms such as agitation and heart palpitation.

The safe limit of caffeine is 400-500 mg per day.
