Ingredients in Relentless Energy Drink
Now that we’ve seen what nutrients you can get from Relentless Energy, let’s now get into the specifics and see the list of ingredients that goes into making this beverage:
- Carbonated Water
- Sucrose
- Acid (Citric Acid)
- Flavour Enhancer (Erythritol)
- Taurine (0.4%)
- Acidity Regulator (Sodium Citrate)
- Preservatives (Potassium Sorbate, Sodium Benzoate)

Flavour Enhancer (Erythritol)
The flavour enhancer, Erythritol, is sugar alcohol usually used as an alternative to sugars.
In comparison to sugar, Erythritol has zero calories to give while regular sugar gives 4 calories per gram.
Although this flavour enhancer is fairly new to the list of sugar alcohols, it’s definitely safe to intake since it was approved by the World Health Organization (WHO).
There are a few benefits you can get from Erythritol which are as follows:
- Unaffected Blood Sugar or Insulin Levels
- Reduced Risks of Heart Disease
However, overconsumption may lead to different side-effects such as:
- Digestive Problems
- Diarrhea
- Bloating
- Cramps
- Gas
The amount of Erythritol you can intake is a gram per kilogram of your body weight. So, it’s best to keep that in mind while drinking this beverage for your safety.
Taurine in Relentless Energy Drink
Taurine is an amino sulfonic acid that is found mostly in our brain, eyes, heart, and platelets in our blood.
Our bodies can produce their own Taurine. However, some can’t which leads them into relying on supplements to get this nutrient.
Taurine can work wonders in your body and it’s limited to this list:
- Supported Nerve Growth
- Lowered Blood Pressure
- Calmed Down Nervous System
- Prevented Heart Failure
- Boosted Energy
- Better Athletic Performance
Despite the tiny amount of this ingredient in energy drinks, there are a few cases where unwanted effects may occur, usually on people with epilepsy or adrenocortical insufficiency:
- Lower Body Temperature
- Higher Levels of Potassium
- Nausea
- Dizziness
- Headaches
- Difficulty Walking
Preservatives (Potassium Sorbate, Sodium Benzoate)
Sodium Benzoate and Potassium Sorbate are two preservatives used in Relentless. Both have the role of preventing molds from growing, spoilage, and preserve the product’s freshness. It’s said to be the most common combination of preservatives.
Sweetener (Sucralose)
Sucralose is an artificial sweetener used as an alternative to regular sugar.
When it comes to its taste profile, Sucralose is said to be 400-700 times sweeter than sugar. Moreover, it doesn’t have a bitter aftertaste like the other artificial sweeteners.
This sweetener also brings good effects to one’s health when the right amount is consumed.
Sucralose benefits include:
- Caloric Intake Control
- Doesn’t Promote Tooth Decay
Sucralose may also have undesirable effects:
- Risks of Diabetes
- Higher Risks of Crohn’s Disease and Irritable Bowel Syndrome
- Links to Leaky Gut
- Possible Production of Toxic and Carcinogenic Compounds in High Temperatures
- Weight Gain
Guarana Seed Extract
Guarana is a source of caffeine that helps revitalise one’s central nervous system, muscles, and heart. It also contains other stimulants like theophylline and theobromine.
This ingredient is a well-known energy supplement due to its high caffeine content. Unlike coffee’s 2% amount of caffeine, guarana has 3.6-5.8% of caffeine by weight, which is needed in an energy drink like Relentless.
If you consume the correct amount, guarana seed extract can give you many health benefits:
- Reduced Fatigue
- Improved Memory
- Weight Loss
- Treated Constipation and Diarrhea
- Improved Heart Health
- Improved Skin Appearance
- Included Antibacterial Properties
- Protection Against Age-Related Eye Disorders
Although, since this ingredient has caffeine, it will give you a few bad effects if not consumed in the right amount:
- Heart Palpitations
- Insomnia
- Headaches
- Seizures
- Anxiety
- Nervousness
- Upset Stomach
- Shakiness
The Vitamins in Relentless Energy
Relentless is packed with the four vitamins Niacin (Vitamin B3), Pantothenic Acid (Vitamin B5), Vitamin B6, and Vitamin B12 that aid your health.
Although all of them are B-Vitamins, they all have their own functions for the body.
Niacin or Vitamin B3 is utilised in your body to turn food into energy. It also plays a role in helping your nervous system, digestive system, and skin stay healthy.
Next is Pantothenic Acid, otherwise known as Vitamin B5. It’s important for one’s body to use its carbohydrates, proteins, and lipids properly in order to convert what you consume into energy.
The third one, Vitamin B6, is crucial for developing the brain and maintaining both the nervous and immune systems.
Lastly, Vitamin B12 helps maintain your body’s red blood cell formation. Moreover, cell metabolism, nerve function, and DNA production are the other purposes of this Vitamin. It plays an important role in our genetic formation.
B-Vitamins, in general, gives a lot of good outcomes to our health, and this includes the aid and promotion of:
- Red Blood Cells Growth
- Energy Levels
- Good Eyesight
- Healthy Brain Function
- Good Digestion and Appetite
- Healthy Cells and Nerve Function
- Cardiovascular Health
- Muscle Tone
However, it’s important to note that while vitamins can do good to our bodies, they can also give symptoms once you overdose:
- Skin Problems
- Bad Eyesight
- Abdominal Cramps
- Nausea
- Vomiting
- Increased Urination
- Diarrhea
How Much Caffeine is in Relentless Energy Drink?
In a 500ml serving, there’s 160mg of caffeine in Relentless Energy.
Although, even with the bigger serving, Relentless is far from the caffeine limit the EFSA suggested.
According to the EFSA, an average adult can consume up to 400mg of caffeine a day for physically healthy adults who do high-intensity workouts.
Despite having that limit, you have to keep in mind that we all have different levels of caffeine tolerance. So, it’s best to see first if you’re even capable of taking 160mg of caffeine.
If you’re new to the world of caffeinated drinks, I suggest you watch this video about caffeine:
How Much Sugar is in Relentless Energy Drink?
Relentless Energy has 24g of sugar per 500ml.
The National Health Service UK (NHS) has recommended that an adult shouldn’t have more than 30g of sugar in 24 hours.
If you’re going to drink the 500ml can with 24g of sugar, I suggest that you should only drink one can a day.
Moreover, you shouldn’t only worry about the sugar amount, but also how sugar can affect your health. The EFSA suggests that continuous consumption of sugar can increase the risks of dental problems, increase weight, and cholesterol.
Is Relentless Energy Drink Bad For You?
In my opinion, I don’t think Relentless Energy Drink is bad for you as long as you drink it in moderation.
Depending on what size you choose to drink, Relentless can be harmless. However, be mindful of its contents and of your caffeine tolerance.

To summarize, you’ll be energized and your overall performance will improve. Although, be careful since it can give you a sugar crash after drinking.
Can You Drink Relentless Energy Drink Every Day?
If you’re someone who has no pre-medical conditions related to caffeine, it’s safe for you to drink Relentless Energy Drink every day.
The larger can is still safe to drink once a day. Despite this, I’d recommend you to limit yourself to drink one can of Relentless Energy drink in order to avoid a negative impact on your health. There’ll be consequences if you drink excessive amounts of sugar and caffeine, so it’s best to keep a safe amount.
Keep track of the amount you’re drinking daily. Although the caffeine in this drink is below what NHS recommended, I strongly urge you to consult a medical professional first and to take their advice.

The energy drink is refreshing, especially with its fruity and tropical flavors. With the amount of sugar, the energy drink also has a sweet and strong taste to power through your day.
The general flavours of Relentless are tropical and unique, so if this is what you enjoy, then I suggest you grab a can and drink in moderation.
Does Relentless Energy Drink Actually Work?
To cut to the chase: Yes, Relentless Energy Drink does work with its 500ml serving!
If you’re going to use Relentless to boost your energy for a workout, the 160mg of caffeine in the larger can is enough for you to get that kick.
Either to boost your physical performance or to lose weight, you will need 100-200mg of caffeine before you do that, which is what Relentless has.
To add up, B-Vitamins can aid with building muscles for men and energy levels for women and vice versa. Vitamin B12 can also help with your athletic performance because of its nutrient support.
Do any energy drinks really work?
Energy drinks can provide a temporary boost in alertness and energy due to their caffeine content. Caffeine is a stimulant that enhances cognitive function and combats fatigue. Additionally, energy drinks might contain other ingredients like B-vitamins and amino acids that contribute to the perceived effects.
However, the effectiveness varies among individuals. While energy drinks can offer short-term benefits, they are not a substitute for healthy lifestyle habits. Relying solely on energy drinks for sustained energy can lead to dependency and potential health risks. Moderation and a holistic approach to well-being are important when considering the efficacy of energy drinks.
Do energy drinks actually provide energy?
Energy drinks do provide a temporary energy boost due to their caffeine content. Caffeine stimulates the central nervous system, enhancing alertness and reducing feelings of fatigue. This often results in a perceived increase in energy and improved cognitive function.
However, this energy boost is short-lived and can be accompanied by side effects like jitters and increased heart rate. Relying solely on energy drinks for sustained energy is not a healthy approach. Balanced nutrition, hydration, regular physical activity, and sufficient sleep are essential for long-term energy and overall well-being.
