How Many Relentless Can You Drink In a Day? (Detailed)

So you’ve started drinking Relentless and loved what the brand offers you. You’re energized, the drink is delicious, and the additional vitamins don’t hurt either.

But you’ve started drinking more and more, and now you’re worried that Relentless might eventually take its toll on you.

I recommend not exceeding more than one 500ml (16 fl. oz) can per day. Its high caffeine and sugar content make it unhealthy to be consumed more than once in a single day.

But then again, there are more factors to consider, so read on to know more details about the Relentless Energy drink!

Nutritional facts of Relentless Energy drink

How Much Caffeine is Relentless?

Relentless contains 160mg of caffeine in its regular 500ml (16 fl. oz) can.

The FDA advises people to not go above the 400mg of caffeine limit per day, so assuming you intake caffeine from other sources aside from Relentless, you can exceed the limit very easily.

The 160mg present in Relentless places the drink among some of the most highly caffeinated energy drinks. This high amount means you will see the results of the drink almost immediately after consumption.

An increase in alertness and a significant adrenaline rush should be expected. It will enable you to carry out strenuous tasks with minimal difficulty.

If you’ve had little to no intake of caffeine in the past, you might want to consider only gradually increasing the dose per day until you’re sure you can take Relentless, to be absolutely safe and to avoid any side effects.

How Much Sugar is in Relentless

Unlike other energy drink brands like Xyience, Moose Juice, and Bang, Relentless isn’t sugar-free.

Each 500ml (16 fl oz) can have 25g of sugar.

People with prior heart and other health conditions should consult with their doctor before drinking Relentless.

The American Heart Association (AHA) recommends women to have no more than 24g and men 36g of sugar per day.

If you’re a woman, Relentless will fulfil 100% of your daily sugar intake limit and for men, this amount is more than 70%.

This might cause health issues if you’re drinking Relentless frequently.

How Many Calories are in Relentless?

Relentless contains 108 calories per 500ml (16 fl.oz) drink.

The NHS declared that the maximum calorie intake for women is 2,000 a day and 2,500 per day for men.

While this amount doesn’t contribute to the daily limit as much as it does with sugar, it can still hinder if you’re on a calorie-restricted diet.

People who are looking to lose weight can consider other calorie and sugar-free energy drinks to add to their diets.

What are the Health Benefits of Relentless?

The main benefits of Relentless are its ability to make you significantly more alert, mentally and physically.

If the energy boost caffeine in Relentless is the reason you’re having the drink in the first place, other ingredients can also play a role in your welfare.

Relentless comes with several B-Vitamins, these include:

These Vitamins aid your body in burning fat into energy and maintaining the body’s red blood cells, these play a crucial role in transferring oxygen within the body, their deficiency could result in anaemia.

What are the Health Risks of Relentless?

If you have two or more Relentless drinks within a 24 hour period, you’re likely to suffer from the following caffeine overdose symptoms.

  • Hallucinations
  • Vomiting
  • Trouble breathing
  • Chest pain
  • Irregular or fast heartbeat
  • Uncontrollable muscle movements
  • Convulsions

If you have had prior health conditions or are a heart patient I would not advise you to have Relentless.

A caffeine overdose can cause high blood pressure and seizures, these can be fatal if you have a weak heart or suffer from any other disease.

What Should You Do If You Experience Relentless’ Side Effects?

If you notice that you’re suffering from one of the symptoms given above, immediately stop all consumption of any more caffeine.

Some common caffeinated products include chocolate, coffee, and tea. In comparison, these three products have relatively less caffeine in them.

Here are a few tips if you’re experiencing some side effects!

Drink plenty of water

The extra caffeine means your body will be working overtime to get it out of your system as soon as possible, this will result in you urinating a lot, to avoid adding dehydration to the list of problems, you should drink as much water as you can.

Take a walk

If you feel packed with a lot of pent-up energy, take a walk and try to rid yourself of some of it. Immediately stop if you feel your heart rate rising.

Replenish nutrients

If you’re urinating a lot, you’re also losing important nutrients. Drinks like Gatorade are specially made for this purpose, it would benefit you to have one.

But if symptoms persist, consult a medical professional immediately.

Can Everyone Drink Relentless?

Relentless is not for everyone, it is only suitable for healthy adults.

Teenagers and children are suggested not to have Relentless because the recommended daily intake of caffeine for teenagers is only 100g per day, Relentless contains a significantly larger amount of caffeine than this recommended limit.

Pregnant women should also avoid Relentless because drinking large amounts of caffeine can cause low birth weight or in extreme cases, miscarriage.

Breastfeeding women are also required to stay away from large quantities of caffeine to avoid affecting the child’s well-being.

If you’re someone who has prior heart conditions, you should consult a medical professional before consuming Relentless.

It can be used before a workout to boost your abilities or even taken after an afternoon nap to stop you from feeling sluggish.

When Can You Drink the Next Can of Relentless?
