Best energy drink for your heart (get good cardio)

Perhaps you’ve been a long-time fan of energy drinks but you’re somewhat concerned about their effect on heart health. If you have any medical conditions or are on medication, there’s a high possibility that you’ll have to completely cut out energy drinks from your life.

But what if I told you that the caffeine in energy drinks isn’t so bad? What if I told you that moderate amounts of caffeine could protect your heart instead?

Several studies have reported that low to moderate doses of caffeine in a day won’t have a negative impact on your heart and could even be beneficial to your health.

If you’re keen to know how energy drinks affect your heart or how the caffeine in energy drinks can help your heart, you’re in the right place…

What do energy drinks contain?

Energy drinks usually contain similar ingredients like caffeine, B vitamins, and sugar that could affect your heart.


Most energy drinks are chock-full with caffeine. After all, caffeine is the main ingredient that reduces fatigue and gives us a good jolt of energyOpens in a new tab. to go on our day without feeling tired.

Besides, caffeine is also great for boostingOpens in a new tab. your physical performance and improving your brain function, which explains why many athletes like to drink a can of energy drink before they play, train or compete.

Energy drinks contain different amounts of caffeine, varying from one brand to another. Even though most people can enjoy a certain degree of caffeine without any after-effects, if you have a sensitivity to caffeine you’ll probably experience a few adverse effects.

That said, too much caffeine can also cause negative effectsOpens in a new tab. like headaches, heart palpitations and dizziness.

If you’re wondering if this means you can’t consume any energy drink at all if you have heart-related problems or are sensitive to caffeine, I’ll get to that in a minute.


Guarana is a Brazilian plant that naturally contains caffeine in its seeds. It’s often included as one of the ingredients in some energy drinks.

However, typically the caffeine from guarana isn’t added to the total caffeine count, so you’ll have to watch out for that. You could end up ingesting more caffeine than you might like.

1g of guaranaOpens in a new tab. is similar to 40mg of caffeine, which is more than a cup of coffee.

That’s a lot of caffeine.

So, pay attention to the labels on your energy drinks before purchasing them to check if they contain any guarana.

A few brands of energy drinks that do contain guarana are Monster and Rockstar.


Sugar is included in many energy drinks to amplify their energy-boosting effects and taste. However, nowadays sugar-free alternatives are available almost everywhere.

A moderate amount of sugar is alright, but consuming an excessive amount might backfire afterward, as it could lead to a sugar-crashOpens in a new tab. and leave you feeling sluggish.

Watch your sugar intake for a healthy heart.

Can you get a heart attack from energy drinks?

Whether or not energy drinks can cause heart problems depends on you as an individual. I’d advise limiting your energy drink intake to no more than one per day and consult your physician for further guidance.

Energy drinks have been linked to increases in heart rateOpens in a new tab. and blood pressure, as well as causing disturbances to heart activity.

In 2019Opens in a new tab., a 26-year-old healthy man from Texas nearly died from a heart attack caused by energy drinks. However, this mostly stemmed from the fact that he consumed energy drinks excessively every day, drinking around 8 – 10 cans in a day.

That’s more than 400mg of caffeine per day!

A 2016Opens in a new tab. study reported that energy drinks could raise blood pressure and increase heart rate, which could lead to the risk of strokes and heart attacks. Another studyOpens in a new tab. showed that energy drinks could affect the heart rate in even young adults.

Energy drinks when consumed in excessive quantities can be harmful and should therefore be consumed wisely.

If you have any underlying health issues, you should control your consumption of energy drinks. It may be hard to abstain from beverages that you like, but in the end, it’s up to you to care for your own wellbeing.

Can energy drinks harm your heart?

Generally, energy drinks aren’t harmful to your heart, unless you have them in excessive quantities. Since energy drinks contain large amounts of caffeine and sometimes sugar, drinking too many energy drinks could lead to caffeine overdose and sugar crash.

If you experience side effects after having any energy drink, it’s most likely because your body is responding to the caffeine. This could probably indicate that you may be sensitive or allergic to caffeine or other ingredients in energy drinks.

With that said, energy drinks aren’t beverages you should be consuming too frequently. Plain water is always the best drink for your health.

To stay safe, just follow the FDA’s daily caffeine intake recommendation (no more than 400mg per day) and you’ll spare yourself any undesirable effects.

Remember to take into account caffeine from other sources which can add up to your total caffeine intake without you realizing it.

Is it ok to drink energy drinks if I have high blood pressure?

If you have high blood pressure, it’s best to first discuss whether it’s safe to consume energy drinks with your doctor. Although it varies for different people, it’s generally okay to drink energy drinks in moderate amounts.

Limiting your energy drink intake and exercising caution should keep you safe from any dangerous adverse effects.

Caffeine has been known to temporarily raiseOpens in a new tab. blood pressure. Though, other research suggests that moderate consumptionOpens in a new tab. of caffeine is unlikely to have a long-term significant effect on your blood pressure or heart.

If you have high blood pressure or any heart-related diseases, I suggest that you go for energy drinks that have minimal amounts of caffeine and sugar.

I’ve also covered the best energy drinks for high blood pressure, which you can read here.

Can caffeine affect your heart?

Caffeine can affect your heart if taken in excessive amounts. For most people, a moderate amount of caffeine doesn’t result in any concerning side effects.

But it becomes a different story if you go overboard with your daily caffeine intake.

According to the FDA, 400mg of caffeine daily should be the limit for healthy adults. If you’re pregnant, breastfeeding, or have any underlying medical conditions, you should first discuss with your doctor if you can take caffeine and if you need to limit your caffeine intake.

For most people, consuming less than 400mg of caffeine per day usually doesn’t lead to any harmful side effects.

But when you consume more than that, it may cause symptomsOpens in a new tab. like:

  • Diarrhea
  • Dizziness
  • Headaches
  • Insomnia
  • Irritability
  • Breathing troubles
  • Confusion
  • Chest pain
  • Heart palpitations

In a few cases, some people might experience an increase in blood pressure, but this usually only lasts around about fourOpens in a new tab. hours.

Caffeine can also affect you considerably if you have caffeine sensitivityOpens in a new tab.. Not to be confused with caffeine allergy, those who are sensitive to caffeine will experience negative effects even after consuming small amounts of it.

When you’re sensitive to caffeine, your body can’t metabolize caffeine the same way regular people do and your symptoms might last for a few hours.

Unlike coffee or tea, several brands of energy drinks can contain up to 300mg of caffeine per can.

Thus, if you want to avoid unfavorable effects, especially if you’re caffeine sensitive, check the ingredients label on the can before making your energy drink purchase.

Caffeine can have a negative impact on your heart.

Can caffeine be beneficial for my heart?

Consumed in moderate amounts, caffeine can be good for your health.

Caffeine can be beneficial to your heart if it’s consumed in moderate quantities. In contrast to many older studies, recent reportsOpens in a new tab. found that moderate amounts of caffeine could have neutral to beneficial effects on blood pressure, cardiovascular diseases and diabetes.

A 2018 study found that caffeine could trigger a proteinOpens in a new tab. called p27 that may have benefits for the heart. When an optimum dose was given to elderly mice, their heart healthOpens in a new tab. improved and their cardiovascular system functioned like younger mice.

However, the benefits of caffeine on the heart is still being explored.

Various studies have reported that there’s a possibility that moderate caffeine consumption could lower the risk of heart diseasesOpens in a new tab. and stroke.Opens in a new tab.

Overall, if you practice controlled daily intake of caffeine, your heart might benefit from the caffeine and experience no side effects at all.

However, even it’s alright to consume caffeine in moderate amounts, your body’s response to caffeine should be the deciding factor in how much caffeine you have per day.

How does sugar affect my heart?

Too much sugar can negatively affect your health and increase the risk of heart diseases. Even though sugar in energy drinks can help boost your energy levels, it won’t last long and will often leave you feeling tired and in a bad mood.

Excessive consumption of sugarOpens in a new tab. can lead to obesity, inflammation, high blood sugar and blood pressure levels, which puts you at risk of heart diseases.

One 2014Opens in a new tab. study found that people who got 17% – 21% of their daily calories from sugar had a higher risk of dying from cardiovascular diseases by 38% compared to those who consumed 8% of added sugar.

A high-sugar diet could also lead to health issuesOpens in a new tab. like:

  • Tooth decay
  • Acne
  • Weight gain/obesity
  • Diabetes
  • High blood pressure
  • Cancer
  • Aging skin

To maintain the wellbeing of your heart and body, I’d suggest following the American Heart Association’sOpens in a new tab. daily recommended sugar intake:

Men150 calories/ 36g
Women100 calories/ 25g

I’m not saying sugar is completely bad. Sugar can be beneficial as fuel to your body in certain amounts, but cutting sugar out completely from your diet won’t be detrimental to your health in any way.

This is why I’d recommend going for sugar-free energy drinks to control your sugar intake.

Is Red Bull bad for my heart?

Small to moderate amounts of Red Bull isn’t bad for your heart. But when you consume Red Bull excessively, you might experience adverse effects like jitters and increased heart rate.

Before you decide whether Red Bull is good for your heart or not, you’ll need to take a look at the main ingredients:

Calories110 calories

In my opinion, Red Bull contains a moderate amount of caffeine that shouldn’t give you too many heart troubles, though this of course depends on your tolerance.

That said, Red Bull does contain high levels of sugar and calories, which would expose you to health risks including heart diseases.

The conclusion?

Stick to one to two cans of Red Bull per day to stay on the safe side and you should be fine.

If you’re still uncertain, do some research and check with your doctor before putting anything into your body.

If you want to learn more about Red Bull, I’ve covered absolutely everything you need to know in another article that you can find here.

Caring for your mental healthOpens in a new tab. also helps protect your heart. So, watch a funny video or gather with your family and friends and have a good laugh.

Best energy drinks for your heart

MatchaBar Hustle Unsweetened Energy Drink

From the name alone, you know that MatchaBar Hustle Unsweetened is entirely sugar-free, so you’re guaranteed to be free from experiencing sugar crashes later on. MatchaBar Hustle Unsweetened energy drink is also great for you if you’re a fan of matcha flavors.

However, MatchaBar Hustle Unsweetened does contain 120mg of caffeine that originates naturally from green tea. Depending on your tolerance, this amount of caffeine might be a little too much for you.

Personally, I prefer to have between 50 and 100mg of caffeine per serve. Any more than that and I often find it a little overwhelming. 

Bing Energy Drink

Bing comes in a variety of flavors.
