Most energy drinks have preservatives as ingredients so as to elongate the shelf life. Before reaching for an energy drink to consume, ensure that it is well within its shelf life and also check if it is open or its still closed.

What is the shelf life of an opened energy drink?

An opened energy drink can has a far much less shelf life as compared to an unopened one. Most companies usually recommend drinking any opened energy drink within 5 to 7 days after it has been opened.

How do energy drinks affect the body?

When you consume energy drinks, the caffeine enters into the blood within some 10 to 20 minutes of taking the drink. This triggers a rise in the heart rate and also raises the blood pressure.

In the coming 15 to 45 minutes, the caffeine levels keep increasing in the blood until they peak. This results in the person who has consumed the energy drink feeling more alert, focused and having a higher level of concentration.

The caffeine blocks a chemical known as adenosine temporarily and this results in an energy boost as it allows other molecules in the brain that help you to feel good such as dopamine to be readily released. This helps you in being more attentive and also feel better about yourself.

All of the caffeine is usually absorbed into the body within 15 to 30 mins of taking the energy drink. By this time most of the sugar contained in the energy drink would have already been absorbed into the body and into the bloodstream.

The effects of caffeine usually wear off anywhere between 1 to 2 hours and the caffeine effects start to wear off and a sugar crash can also occur. You will feel your energy levels begin to drop and you might start feeling tired.

It takes about 5 to 6 hours for the amount of caffeine in your bloodstream to be reduced to 50 percent which is known as the half-life.

It takes an average of 12 hours for caffeine to be completely eliminated from the body of most individuals however this also depends on certain factors such as:

Age

The speed and efficiency of caffeine elimination from the body increases with age and its more for adults. As mentioned earlier, the half-life of caffeine is about 5 to 6 hours in adults in comparison to younger people like infants where it averages a good 80 hours.

Genetics

Genetics play a lot of roles in how our body metabolizes caffeine among other things. Studies have shown that people with some genes tend to break down caffeine much faster and some have been reported to break it down 40 times faster than other people.

This goes to show that some people may have faster metabolism and erection of caffeine while for others it might take much longer.

Body Height/Weight/Fat

A person’s height, weight and body fat can also affect the speed in which caffeine is metabolized by the body. It has been shown by studies that a person that tall and heavy is more likely to clear 100 mg of caffeine much quicker than a person that’s short and light.

As a rule of thumb, the greater the caffeine dosage taken relative to a person’s body since the slower it takes for the person to break it down, the converse is true. As known, people with high body fat generally have a greater rate of metabolism and will therefore break down caffeine much faster.
