Before you know the consequences of consuming an energy drink, you need to understand the drink’s nutritional value. On the first note, the energy drinks contain synthetic caffeine, your only reason for gulping them!

They can have about 200 mg of caffeine per pack. And another list of substances that are supposed to revamp your energy levels is B vitamins and herbs such as guarana and ginseng, etc., which are natural or plant-based caffeine.

How Do Energy Drinks Affect Our Body Within The Next 24 Hours After Consumption?

To know how long energy drinks last in our body, it’s essential to understand the breakdown right after these juices enter our mouth. The caffeine from the energy drink enters the bloodstream right within 10 minutes of consumption.

The levels of caffeine within the bloodstream go to peak within the next 15-45 minutes after consumption. Consequently, an individual will experience better concentration and will feel more alert. 

All caffeine in an energy drink is absorbed within around 50 minutes after its consumption. As a consequence, your liver starts absorbing more sugar within the bloodstream. 

And, it just needs an hour approximately to confront some of the vanishing caffeine from the body. It further leads to sugar crashes in your body. Tiredness will set in, and the energy levels will feel low.

To achieve an almost 50% reduction in the levels of caffeine in the bloodstream, it will take around 5-6 hours. This procedure is also known as the ‘half life’ of the energy drink. 

Therefore, it takes an average of 12 hours for your body to entirely subside the effect of caffeine contained within the energy drinks. So, an ideal answer on how long energy drinks last is approximately 12 hours. 

You must also note that the period can even double if you’re taking birth control pills or pregnant. This is because it slows down the rate of eliminating caffeine from the body. 

Different Time Stages On How Your Body Experiences Energy After Consuming Energy Drink

10 Minutes It needs around 10 minutes for the caffeine within the energy drink to enter the bloodstream. After 10 minutes, your blood heart rate and blood pressure begin to boom.
15 – 45 Minutes The stimulant starts impacting your energy levels within 15-45 minutes of consumption of an energy drink. In addition, the caffeine levels peak in these intervals improving both your alertness and concentration.
30 – 50 Minutes During 30-50 minutes, the caffeine gets entirely absorbed within the body. Your liver also begins to respond while absorbing more sugar within the bloodstream.
1 Hour During 1 hour, caffeine starts dying, and your body begins to face a sugar crash to make you feel drained and low on energy levels. However, the effect of caffeine is still there, and it hasn’t gone completely. 
As mentioned earlier, the process is even slow in case of pregnancy or other diseases such as liver damage, etc.
5 – 6 Hours This is when caffeine enters the half-life stage, as we’ve already discussed. Almost 50% of the caffeine from the bloodstream has vanished by now.
12 Hours It is the time when the caffeine entirely vanishes from the bloodstream. However, the process and speed are generally based on age, activity, etc.
12 – 24 Hours It is the period when you confront caffeine withdrawal symptoms which are often headaches, irritation, constipation, etc.
7 – 12 Days If you’re habitual of consuming caffeine daily, then 7-12 days is when your body becomes tolerant to the regular dosage. But unfortunately, it means that you’ll get used to the caffeine, and the body also doesn’t respond to the effects of energy drinks much by this period.
