What is the fastest way to get caffeine out of your system?

One of the fastest ways to get caffeine out of your system is by taking activated carbon to bind to the caffeine molecules and remove it out with stool. You can as well take plenty of water to flush caffeine out. This is because caffeine is a diuretic and as you drink lots of water, you will urinate a lot and get rid of it. 

There are also some other ways that can be used to get caffeine out of your system such as, avoiding consumption of caffeine and waiting for the caffeine to clear naturally. We will look at these ways in depth briefly.

How much caffeine is too much?

The amount of caffeine that you can consume is largely dependent on a lot of factors such as your health condition, age, genetics, weight and your liver’s ability to process it. Caffeine is not safe for everybody and there are specific persons that need to avoid it. For example, the below category of people should steer clear of caffeine

  • Young children
  • People that are on anti-anxiety meds
  • Pregnant and breastfeeding women
  • People that have heart diseases or a High blood pressure

For healthy persons,  caffeine is safe if taken in moderation. Below are some of the boundaries that you should adhere to:

  • For healthy adults, it is recommended not to consume more than 400 mg of caffeine in a day. That is the equivalent to about four 8-ounce cups of brewed coffee 
  • For teens, they should limit their caffeine intake to less than 100 mg per day which is about an 8 ounce coffee cup. 

What are some ways to clear caffeine out of your system?

Use of activated carbon to bind to the caffeine and remove it

Activated carbon is a great way to get caffeine out of your system quickly. Activated carbon is available as tablets over the counter in most pharmacies and requires no doctor’s prescription.

It usually has a porous texture with very little holes and does not get absorbed into the intestines. Even after swallowing activated carbon, it remains unchanged.

As a result of these features, activated charcoal is able to bind to a wide variety of toxins through absorption and is effective in removal of such toxins through the stool prevention absorption in the body system.

Caffeine can be effective in binding the caffeine molecules and helping in depleting the extra serum caffeine.

Hydrating with water to flush out the caffeine

Taking plenty of water to hydrate can also help to eliminate excess caffeine from the system. If you have just a mild caffeine overdose then oral hydration should suffice.

Hydrating with water is important as it assists in the detoxification process. Although there is scarce research on the topic, some studies do show that drinking enough water can help in flushing out the caffeine out of the system much faster.

Stop consumption of coffee

This is really a no brainer. Caffeine consumption can be really addictive and it makes sense as it helps in boosting mental alertness and boosting your energy levels.

Caffeine can have effects on sleeping patterns because it influences the functioning of adenosine which is a neuromodulator in the Central Nervous System (CNS)

Adenosine leads to effects such as drowsiness by lowering any neural activity,dilating blood vessels and triggering sleep. Caffeine works by binding with the receptors of adenosine and therefore prevents them from functioning.

If you happen to have side effects of too much caffeine such as difficulties in sleeping, it is important that you steer clear of taking caffeine.

Wait it out to clear out of the system

Caffeine’s stimulatory effects usually peak within the first forty five minutes after ingesting caffeine and they can last for about 3 to 5 hours.

It can take even ten hours for it to completely be flushed from your system. If it happens to affect your sleep then avoid consuming it 6 to 8 hours before going to bed.
