You might be surprised to learn that energy drinks are not always a great choice for people who have diabetes. There are many reasons why energy drinks may not be right for you, but the main one is sugar content. Drinking sugar-free energy drinks with caffeine in moderation might actually help keep your blood sugar levels steady as they provide an energy boost without causing a spike in blood sugar levels like regular energy drinks do.

In this Diabetic & Me article you will learn about:

  • Is caffeine safe for a diabetic?
  • Can a diabetic drink Red Bull or Monster?
  • Do energy drinks spike blood sugar levels?
  • What are other drinks a diabetic can consume?

I never drink energy drinks as I'm too sensitive to caffeine and to be honest I don't like them at all. I received questions about this topic from my blog readers and therefore decided to write a little blog post about it. To cover this blog post I asked some of my diabetic friends to test sugar-free energy drinks. In this blog post, I will list some of their favorite diabetic-friendly energy drink options and review what makes them so amazing.

How much caffeine is safe for diabetes?

It's only natural that life is hard and we need all the help we can get. Our bodies are always running on fuel, which sometimes gets depleted faster than it should. And when that happens, hormones like norepinephrine have a negative effect on the brain by depleting energy levels among other things. We need to feel superhuman from time to time in order to achieve our goals. That requires enough energy to think outside of one's comfort zone and use multiple cognitive processing centers simultaneously. 

Consuming caffeine is not a problem for people with diabetes as long as it is consumed in moderation. The FDA created a guideline that an average adult should not exceed 400 milligrams of caffeine per day.

Since I am very sensitive to caffeine I always test first how much my body can take. Start with lower intakes of a caffeinated drink like coffee, Cola Zero, green tea, or others. I recommend you also test where your limit is and make sure you don't feel any negative sides from your caffeine consumption.

Test your blood sugar levels with a blood glucose meter every day when you are consuming energy drinks with caffeine. One way that energy drinks might cause a spike in blood sugar levels is if the energy drink contains sugar. If your energy drink doesn't contain sugar but still makes you feel bad, causes high blood sugar levers or high blood pressure, then stop drinking energy drinks altogether.

Consuming energy drinks with sugar will lead to blood sugar spikes, but energy drinks without added sugars are safe and can even provide an energy boost for those who have diabetes when they are feeling low on energy.

Are sugar-free energy drinks safe for diabetics?

This question is difficult to answer because energy drinks provide energy and a sugar-free energy drink might contain other ingredients that could be harmful to those with diabetes. That being said, energy drinks in moderation have been found safe enough by the FDA approval process to not list them as unsafe for consumption on the market.

Most sugar-free drinks still contain artificial sweeteners that are not always the best option for people with diabetes. They don't cause blood sugar spikes but might be harmful to your body. The issue is that most sugar-free energy drinks contain artificial sweeteners, which are not always that healthy.

However, energy drinks like Red Bull and Monster Energy contain sugar in the form of high fructose, corn syrup, or sucrose. These sugars are very bad for your body because they will cause blood sugar spikes that can lead to many health problems related to diabetes. The best option is a sugar-free energy drink if you want to drink one.

Which energy drink is best for diabetics?

There are many reasons why regular energy drinks may not be right for you, but the main one is the high sugar content. Therefore sugar-free energy drinks are a great option for diabetics.

The energy drink that got favorited by my friends is the one from Red Bull that contains 0% sugar. Down the line they found Monster Energy drink and C4 Smart Energy drink also very enjoyable.

It also helped them greatly because when their energy levels were low and they needed an energy boost to get through the day. The downside of these energy drinks is that you should only consume it in moderation. 400mg caffeine per day is the maximum according to the FDA guideline.

The best thing to happen to energy drinks since Red Bull. With no sugar, Red Bull Sugar-Free is a nutrition all-star. Active ingredients like caffeine and taurine stimulate the central nervous system for an explosive high or low dose of blissful buzz while only 5 tasty calories per can keep things needlessly complicated.

Is taurine bad for diabetics?

The substances taurine and glucuronolactone (precursor of taurine) are standard ingredients of energy drinks. Taurine plays a role in metabolism, but how it works is not yet fully understood. It is clear that it stimulates the absorption of fats from food.

Taurine is also obtained with the daily diet, about 58 mg. It can vary from 17 mg to 1000 mg. There are some indications that taurine has a beneficial effect in diabetes mellitus type 1 and 2. This has been shown in particular in studies with rats and never insufficiently large clinical studies [1-2]. In conclusion, there is currently no evidence that regularly drinking light version of energy drinks containing taurine and caffeine is unfavorable for people with diabetes mellitus.

Do sugar-free energy drinks spike blood sugar levels?

It depends. Sugar-free energy drinks without artificial sweeteners don't do a thing but energy drinks with sugar content spike blood sugar levels. In order to avoid an energy drink-induced blood sugar spike, be sure to read your labels carefully and consume them in moderation, as you would treat any other food or beverage that contains sugar.

People with diabetes should know that energy drinks can affect their glucose levels due to the high level of caffeine and sugar found in many energy drink formulations. And while natural sugars present in some energy drinks don't raise blood glucose levels, there are still plenty of other sugars out there which will lead to spikes if you have diabetes.

Can a diabetic drink Red Bull or Monster Energy?

The answer is no, energy drinks with sugar content will raise blood sugar levels. Sugar-free energy drinks without artificial sweeteners are safe to consume for diabetics. So if you choose the sugar-free versions of Red Bull or Monster Energy you are fine.

Always test your blood sugar levels once after you consume a sugar-free energy drink to make sure it doesn't affect your blood sugar level negatively. It's important you reduce your sugar intake to avoid high blood sugar levels.

What other drinks can diabetics consume?

Diabetics can drink sugar-free diet drinks, sugar-free sodas, sugar-free coffee, sugar-free tea, sugar-free hot cocoa, coconut milk, coconut water, and sugar-free energy drinks. But above all, the best drink is plain water.

During the summer times, you can always use mint, lime, or adding aloe vera pulp to your water to give it more taste. Making a homemade iced tea is a great substitute for your regular drinking water.

Avoid drinking sparkling water and stick to flat water, alcoholic beverages, and drinks with high sugar and caffeine content.

If you have a low blood sugar level you can drink drinks with sugar content to regulate your blood sugar.


We hope this article has helped you learn about energy drinks for diabetics. It is important to be aware of what energy drink may work best with your body and lifestyle, as some can have dangerous side effects on a diabetic's health. Be sure to do your research before making any purchases or consuming energy drinks so that you know they are safe!
