Redline Energy Drink Review (Truth revealed)

Redline Xtreme is one of the most potent energy drinks in the market right now. I’ve sampled a lot of energy drinks in my time and the caffeine content usually ranges from 50-250 mg only.

But lo and behold, I discovered that Redline Xtreme has 316 mg of caffeine! That’s very high. In comparison, Red Bull only has 80mg of caffeine per 250mL can. On the bright side, Redline does not have any sugar or calories and it comes in seven different flavors.

Just looking at the caffeine, Redline definitely gives a strong energy boost. Much stronger than what I usually prefer, actually.

But nevertheless, I had to try Redline just once to see if it really is as strong as it claims. In my opinion, even though I really dig the tangy aftertaste of Redline, I am not an avid caffeine fanatic, and such a large volume of caffeine in a single can gives me the jitters I even had trouble sleeping the following night.

So, therefore, I won’t recommend this for people with low caffeine tolerance or those with medical conditions.

But if you’re interested in knowing more about Redline, I suggest you keep on reading my review!

Caffeine Content In Redline Xtreme

There is 316mg of caffeine in a single serving of Redline Xtreme.

Due to the high caffeine content of Redline Xtreme, I’d only recommend it for those who have high caffeine tolerance and are in good physical condition.

According to the FDA, the recommended limit for adults is only up to 400mg per day. Excessive consumption may result in the following health issues:

  • Anxiety
  • Dehydration
  • Insomnia
  • Restlessness
  • Dizziness
  • Headaches
  • High Blood Pressure
  • Irregular Heart Rate
  • Addiction

Caffeine, in general, is a stimulant that can offer some health benefits. However, do moderate your consumption! Especially if you are a beginner at caffeinated drinks or you have a low caffeine tolerance.

Here are some of its benefits!

  • Boosted Energy
  • Improved Physical Performance
  • Increased Focus
  • Improved Reaction Time
  • Lowered Risk for Type 2 Diabetes.

Sugar Content In Redline Xtreme

If you are looking for a product that does not contain added sugar, then you’d enjoy Redline Xtreme.

You will consume no extra sugar while drinking Redline Xtreme. It’s also great for controlling sugar intake since Redline Xtreme won’t affect it as much with drinking.

Although it doesn’t contain any sugars, it does, in fact, contain sucralose, which is a highly concentrated sweetener that gives the drink a surprisingly sweet taste while being calorie-free too.

Reduce sugar intake in your diet to improve your health in the following ways:

  • Higher energy levels
  • Boosted immune system
  • Better Sleep
  • Weight Loss
  • Improved Gut Health

According to the AHA, a woman’s sugar intake should be no more than 24g (6 teaspoons) per day and should be no more than 36g (9 teaspoons) for men.

You may experience the following health problems if you consume sugar above the recommended amount:

  • Obesity
  • Diabetes
  • Risk of Heart Disease
  • Risk of Cancer
  • Acne
  • Tooth Decay
  • Skin Ageing
  • Low Energy

While zero-sugar energy drinks can be great for those on a diet or are diabetics, I’d still say that Redline’s caffeine content can pose some negative effects.

In fact, some studies suggest that diabetics should keep their caffeine intake to no more than 200mg a day since copious amounts can affect their blood sugar levels.

Calories In Redline Xtreme

There are no calories in Redline Xtreme.

According to the NHS, women require approximately 2000 calories per day, whereas men require up to 2500 calories per day. However, many factors, including age and lifestyle, can affect this.

Since Redline is calorie-free, you won’t need to worry about your diet or gaining weight. But again, because of its high caffeine content, I think Redline would be better for those who regularly do heavy workouts daily.

In general, it’s ideal to maintain a proper diet and exercise to be healthy! Energy drinks are just there to give us a helpful boost and we shouldn’t rely too much on them.

Vitamin C

Your body needs vitamin C to function properly. As your body cannot produce the nutrient naturally, you get it from your diet.

It’s also known as ascorbic acid and has several antioxidant properties and various health benefits such as:

  • Reduced risk of chronic diseases
  • Managed High Blood Pressure
  • Lowered risks of heart disease
  • Iron deficiency prevention
  • Boosted immunity
  • Improved memory


L-Tyrosine is another mineral included in Redline and they’re known for improving concentration and cognitive abilities.

Hence, you may have encountered L-Tyrosine in supplement form before. Aside from enhancing your mental performance, it also helps in the production of protein in your body and boosts nerve function.

Energy drinks like Redline Xtreme usually contain them since they increase attention and focus.

5-Hydroxy-L-Tryptophan (5-HTP)

Redline Drinks also contain the chemical compound 5-hydroxytryptophan (5-HTP) that can be converted to serotonin in the body and is often used to treat depression. Other reports have also stated that the compound can be effective in treating insomnia and anxiety.

5-HTP is a chemical byproduct of a protein building block. 5-HTP works in the brain and central nervous system by increasing the production of the chemical hormone serotonin.

Serotonin can affect sleep, appetite, temperature, sexual behavior, and pain sensation. Another name for serotonin is the “feel-good” hormone, as it helps in improving mood and building satisfaction.

Is Redline Xtreme Good For You?

If you have a high caffeine tolerance and regularly do strenuous activities, then Redline can provide a good energy boost for you.

However, even if you are caffeine tolerant, I don’t really recommend making a habit of drinking Redline regularly since it might lead to caffeine dependence or overdose.

If you are thinking of trying Redline, you should consume half a serving first and see if its effects on you are manageable.

Lastly, limit yourself to one bottle of Redline a day only! Going beyond that can cause adverse effects.

What Happens When You Drink Redline Xtreme?

Due to the amount of caffeine in Redline Xtreme, I felt more energized while completing complex tasks such as doing my maths homework and working out, so it is best to consume it during periods that require large amounts of concentration and energy.

In my experience, the caffeine boost kicked in around 15 minutes after I first started drinking. Then, I felt my heart rate increase and I became more alert.

The boost hit its peak around the 1-hour mark and I felt very buzzed and restless. It did help me accomplish my tasks, but I didn’t really like the accompanying crash after about 4 hours.

I also had a bit of trouble sleeping that night and I felt a bit lethargic in the morning. But then again, it’s probably because I don’t usually consume such highly-caffeinated drinks and Redline’s caffeine was such a surprise to my system.

In my opinion, there are other energy drink brands out there that can give you a substantial energy boost without the pesky crash symptoms.

If you do want to try Redline, you should take it in the morning so the caffeine won’t mess up your body clock at night.

Can You Drink Redline Xtreme Every Day?

No, Redline Xtreme shouldn’t be consumed regularly.

Drinking energy drinks only occasionally or on special occasions is the best way to reap the benefits. Regularly consuming them will make your body accustomed to them and induce caffeine tolerance.

316mg of caffeine is a very high amount for daily consumption. It would be best if you didn’t have this much caffeine every day, no matter how high your tolerance is.

Caffeine can cause you to become addicted to energy drinks, which can harm your health in several ways:

  • Fatigue
  • Low energy
  • Decreased alertness
  • Drowsiness
  • Bad mood
  • Difficulty concentrating
  • Irritability
  • Feeling foggy

Side Effects Of Redline Xtreme

You would not experience any side effects if you could limit your consumption.

It is recommended not to drink Redline Xtreme excessively as excessive consumption may result in these side effects:

  • Nervousness
  • Restlessness
  • Trouble sleeping
  • Caffeine overdose
  • Stomach irritation
  • Muscles twitches
  • Increased heart rate

Flavors Of Redline Xtreme

Seven different flavors of Redline Xtreme are available. Here is a list of those flavors.

  • Blue Razz
  • Cotton Candy
  • Sour Heads
  • Star Blast
  • Triple Berry
  • Lime
  • Watermelon

Blue Razz is my favorite out of all the Redline flavors I tried. It’s very fruity and sweet and the blueberry aftertaste is very pleasant.

All the flavors in general are very sweet due to the Sucralose added, but there was no terrible sweetener aftertaste that I often encountered in other zero-sugar energy drinks.

One flavor that I disliked was the cotton candy one; It tasted like one of those cough syrups given to children. It was sweet and had a sort of semi-umami aftertaste. I’d also like to mention that cotton candy, in particular, packed a punch even though all of the flavors have the same caffeine content. Jitters and sweating were exceptionally prominent with this one.

Final Thoughts

Redline was definitely not kidding about its strong caffeine content. In my opinion, the drink does its job and the flavors are nice, but at the end of the day, it isn’t for everyone.

As I said earlier, I’d recommend Redline for those who are used to high caffeine content and are in good health. But even then, it’s not ideal to get used to drinking such a high amount every day and I’d caution you against drinking Redline often.

It’s important to moderate your consumption of any caffeinated product. Start small and take it easy since the side effects may overwhelm you. If you do experience sever caffeine symptoms, consult a medical professional immediately!
