Four cans of NOS energy drinks in different flavors.

A quick answer: based on the daily recommended caffeine and sugar intake, it is safe to consume 1 to 2 cans of NOS per day. This number will allow you to enjoy other food and beverages without risking caffeine or sugar overdose.

NOS, as you probably know, is a high-performance energy drink. It comes in six awesome flavors which are packed with B-Vitamins, taurine, and caffeine.

But if you are keen on drinking NOS every day, you should probably ask yourself, how many cans are safe to consume per day?

If you want to delve more into the details, keep reading!

Here, I’ll share with you the reasons behind the safe estimate given by credible sources. I will also answer some of the questions you might have about the effects of drinking too much NOS energy drink.

How strong is NOS Energy Drink?

Nutrition facts of NOS energy drink.

NOS is considered an average to moderately strong energy drink based on its caffeine content at 160 mg.

Other energy drinks in the market have a caffeine content that ranges from around 80 mg like Red Bull to 200 mg like 5-Hour Energy.

So in my judgment, the caffeine level of NOS is pretty much agreeable.

Red Bull8.4 fl. oz80
Amp16 fl. oz142 mg
Monster16 fl. oz160 mg
Rockstar16 fl. oz160 mg
NOS16 fl. oz160 mg
Full Throttle16 fl. oz160 mg
5-Hour Energy1.93 fl. oz200 mg

Based on my experience, NOS really delivers its promise of giving you an energy boost and enhancing your mental sharpness.

You will begin to feel the effect of this energy drink just after 15 to 30 minutes of finishing a can.

After that, I realized the effect usually wears off after a good 4 to 5 hours. The hours may vary depending on your day-to-day task and sensitivity to caffeine.

If you want to feel the quickest energy boost possible, I recommend trying the NOS Original flavor variant. Based on my experience, this NOS variant demonstrated the quickest boost on the body.

However, before you explore the energy drinks I listed above, I strongly advise that you test or build your caffeine tolerance first before going straight to high-powered drinks.

This way you’ll get a clear picture of how your body reacts to consuming a certain level of caffeine.

Now, let’s move on and discuss the central question.

How many cans of NOS energy drink is too much?

More than two cans of NOS Energy drink a day is already too much and considered risky, based on the daily recommendations of sugar and caffeine intake proposed by the Food and Drug Administration.

According to the FDA, 400 mg of caffeine is the recommended limit per day.

Based on this, simple math will let you know that if you drink two cans of NOS containing 160 mg of caffeine you will be consuming around 320 mg of caffeine a day.

Drinking a third can of NOS will then give you 480 mg which exceeds the caffeine limit.

So, more than two cans per day will be very risky especially if you’re sensitive to caffeine.

Plus, drinking more than two cans per day will also make you more prone to some of the reported side effects of caffeine overdose such as:

  • very fast or irregular heartbeat
  • shakiness
  • feeling sick or vomiting
  • confusion
  • panic attacks
  • chest pain
  • vomiting

Certainly, the safest way to avoid all of these serious complications is just to enjoy at most two drinks per day.

Does NOS Energy Drink make you fat?

Is NOS the culprit for your weight gain?

Energy drinks such as NOS increases the amount of sugar and calorie content of your body. However, it does not necessarily make you fat if consumed in healthy intervals and paired with regular exercise.

Sugar is one of the primary ingredients in energy drinks because it helps increase the energy in your body. Most energy drinks use sugar varieties such as high fructose corn syrup, acesulfame potassium, and sucralose.

A can of NOS contains 54 mg of sugar per 16 fl. oz can. (about 2 serving)

If you’re worried that this might be too high, you’re right! This is way above the limit set by professionals for a healthy sugar diet which is:

  • 24 grams of sugar, female
  • 36 grams of sugar, male

The sugar found in NOS is a bit excessive compared to the formulation of other energy drinks. See the table for your reference.

Energy DrinksSizeSugar Level
Red Bull8.4 fl. oz27 grams
Amp16 fl. oz29 grams
Monster16 fl. oz54 grams
Rockstar16 fl. oz24 grams
NOS16 fl. oz54 grams
Full Throttle16 fl. oz29 grams
5-Hour Energy1.93 fl. oz20 grams

So the bottom line here is, drinking NOS increases your chance to get fat because of high sugar content. But it can be avoided if you consume it occasionally and drink it to prepare your body for heavy workouts.

What does NOS Energy Drink do to your heart?

Be mindful of the effects of energy drinks on the heart.

Energy drinks, such as NOS, may cause an increase in blood pressure and heart rate. Depending on the amount of caffeine content and other stimulants, it may also cause a strain in the heart and blood vessels.

While energy drinks do a good job in improving physical performance and brain function, some studies have found connections between energy drinks and some heart complications.

According to the National Institute of Health, there are more than 200,000 cases in the US where a patient visits the emergency room because of excess energy drink consumption.

Energy drinks often come with a high concentration of caffeine. Bang, Monster, and Reign Total Body Fuel are some examples of energy drinks with “high caffeine content.”

Drinking too many of these energy drinks can increase your risk of heart attack, stroke and other dangerous heart problems.

It’s not only the caffeine that makes energy drinks bad for the heart but the combination of ingredients in it.

So, drinking NOS in moderation, exercise, and balanced diet are the keys preventing heart issues.

In my experience, as long as NOS is consumed in healthy intervals, it is unlikely that it will harm your heart.

What does NOS Energy Drink do to your kidney?

Good or bad for your kidneys?

Moderate intake of NOS Energy Drink is not harmful to your kidney. It only becomes dangerous when consumed more than the recommended amount and combined with alcoholic beverages.

Based on the research of a health journal, daily energy drink consumption may trigger acute kidney injury, especially when ingested with liquor.

This is because when you consume an energy drink, your body delays the effect of alcohol which will make you feel sober even when, in reality, you’re actually drunk.

The end result is that you will have consumed more alcohol than your body can actually handle. This will spike your blood sugar, heart rate, and worse, cause renal failure.

To get a better grasp about the dangers of mixing alcohol and energy drinks, see this article from CDC website.

Remember, our kidney’s main function is to filter the substances inside the body and get rid of body waste in the form of urine. You wouldn’t want to abuse it.

My takeaway here is the saying, “the dose makes up the poison.”

When consumed moderately, an energy drink can actually help you improve your performance and concentration.

However, keep in mind that it should not be abused to the point where you compromise your organs.

Can NOS Energy Drink kill you?

NOS Energy Drink, depending on your consumption, may be harmful to your health. However, the instances where energy drink overdose can be life-threatening is very rare.

It is believed by experts that as long as you closely monitor the caffeine and sugar level, it should be safe to consume NOS, as well as other brands of energy drinks.

My additional note here is that depending on your health status, consider other pre-existing conditions you might have—for instance, high blood pressure, allergies, or a history of diabetes.

Considering pre-existing health conditions are important, because chances are, your body might react differently if you consumed NOS regularly.
