      Advantages

      Disadvantages

      A great pick me up and cheaper than it's rivals.

      I will start this with I am a confirmed caffeine addict and drink so much every day it is unbelievable. Relentless is a caffeine drink to Rival the leader Red Bull.

      When I first saw it in the shops I remember thinking it looked great with fantastic styling and at the time it was the same price as a can of Red Bull but I got twice as much.

      At the moment this is sold at Tesco for £1 a can which is cheaper than some but more expensive than the own labels which sell for around 90p a liter. I would personally rather pay a little more for Relentless as I have found it to have a unique taste I can not pinpoint it but there is a more fruity flavour to go with the full on chemical hit I normally tend to get from these drinks.

      In conclusion I would recommend this to anyone wanting a quick pick me up weather you are going on a night out or just need to stay awake for work or an assignment.

        Disadvantages

        I prefer monster energy drinks, but it's personal opinion

        I love energy drinks, not just for the energy but for the taste. I'm a big fan of red bull but find it ever so expensive for such a small can. My favourite energy drinks are the supermarket 'own brand' versions such as tesco's red rooster, and 'kick'. They only cost about £1 for a litre bottle, and they have a cheap taste that I have grown fond of.

        Relentless is a premium energy drink, it's expensive but better value than red bull as it comes in a rather large 500ml can (the can's aren't as handy as bottles because you have to drink the whole thing in one go, which can be too much caffeine sometimes). I'd never buy a can of this on it's own (too expensive) but I tried one as part of a meal deal and I have to say I was disappointed, I'm a big fan of the 'monster' energy drinks, particularly 'ripper' (the one that tastes more like fruit juice) and compared to that Relentless was clearly an inferior product.

        It is of course completely subjective, but I found that relentless tasted very artifical (and for an expensive product that's not acceptable), it is also very gassy compared to monster, I even prefer the can design of monster.

        Personally I prefer monster, but both have a good caffeine kick.

        Advantages

        Disadvantages

        Better than Red Bull, the energy effect is longer lasting

        Relentless is a great tasting energy drink from the makers of Coca-Cola.

        It comes in tall brown cans, cans that look a little masculine and different from the norm.

        Relentless tastes great. It has a really refreshing taste that's sweet but not as sweet as Red Bull. It tastes a little like Monster but I prefer the taste of Relentless. The tall can can be a little bit of a problem though. If I drink the whole can it leaves me feeling somewhat bloated and very windy. This bloating effect can be a little uncomfortable so I usually transfer mine into a plastic drinking bottle and sip it freely. I think these 500ml cans are on the large side and smaller 250ml cans (or bottles) would be better.

        The drink gives me an energy boost, although it takes longer to kick in compared to Red Bull. Red Bull works almost straight away whilst Relentless needs a little time to kick in. However, when this drink kicks in it KICKS IN. This leaves me going for hours. It's great for sipping at work as it helps me to concentrate on what I am doing and it stops me from flagging halfway through my shift. The drink leaves a pleasant aftertaste in my mouth after drinking and it helps to quench my thirst. It tastes better chilled as opposed to room temperature.

        You can also drink this drink with food. It really helps to refresh your mouth and it washes your food down well. This drink costs around £1.30 per 500ml can. Not too bad in value really. Try it!

        Advantages

        Disadvantages

        Another good energy drink alternative

        In the last few years the UK seems to have succumbed to the US's drinking habits and seen the introduction to American styles, such as I live in a small city where there are approximately 6 coffee shops, just the Costa/Nero style ones, not even the original British ones that were existingly there. We have also seen a huge rise of the number of different energy drinks that we find in our local shops shelves. A few years a go you might not necessarily have even a red bull on the shelf however now it's a shock to not see Rock star, Relentless, Monster and the others with the different flavors and types they come with.


        As with the increase of them comes the competition, as Red bull started to get more popular in the UK i think that Relentless was one of the first companies to see the niche that they had in the market here and that they were practically unrivaled across here. This was when they first started to sell their beverages here a few years ago. The relentless canned drink in my opinion is much better than the traditional Red bull. For starters it is regularly on promotions such as £2 for 2 and other mix and match deals meaning you can get it for the price of something like a coke. Relentless also has a much sweeter flavor, the actual aroma and taste are quite distinct but hard to pin point, it has a somewhat fruity flavor that is liked by most. Relentless also does have a variety of flavors meaning that their is a chance that you're going to at least like one.


        I would definitely recommend this beverage to anyone who drinks their energy drinks regularly as this is one of the nicer ones that are available, definitely tastes better than original Red bull. It can also be a cheap alternative to some as Red bull is much more expensive than the other and no better in terms of contents.

        Disadvantages

        An energy drink by Relentless

        I am not a big fan of energy drinks, as I don't think they are very good for you, however sometimes during the week I just get those moments where I am practically nodding off at my desk or days that I am so busy that if I don't have an energy drink I will not last the full day. I used to be a fan of Red Bull but then it was just too sweet for me which is why nowadays when I need a pick me up, I purchase Relentless as I think their drinks taste a lot better and I just like the overall image of the brand and they are very popular.

        PACKAGING

        The cans of Relentless are very tall and are a brown colour with a metallic look to them. They have the logo going down the side of the can and then on the reverse they have all of the nutritional information and the list of ingredients. It's a really nice design and it definitely stands out bold on the shelf as they logo is very gothic looking and unique from other modern day looking packaging. In a typical can you get 500ml which is more than enough.

        RELENTLESS

        Before drinking Relentless, I made sure that I checked out the nutritional information first as I don't like taking in too much sugar. In a typical 100ml of a can this contains 46 calories, 10.4g of sugars, 0g of fat, 0g of saturates and 0g of fibre. As you can see it does contain quite a lot of sugar but this is expected as being an energy drink it is almost inevitable that sugar is what is going to give you the energy. It isn't healthy to drink this regularly but it is alright the odd time.

        This drink got me through late nights at university but I have seen people become addicted to it and drinking it all of the time, that is definitely not good. As soon as you open the can you can smell the sweetness of the drink, to drink this it does taste sweet but in a right balance not overly sweet and it has a sugary taste with a bit of fizz to it and it really is quite nice to drink with food or just on its own, it is nice but it hardly quenches my thirst.

        The drink doesn't perk me up right away but after about an hour or so, sometimes less, I can feel this taking effect and it does actually make me feel a lot more energetic. Relentless is best consumed in the day but not too late at night or you will never feel ready to go to bed as it'll make you feel really awake. I only take this when at work when I need energy to keep my mind going and it usually does the job just fine which is why I still keep buying it.

        I'd recommend Relentless to anyone who likes a sweet drink, or energy drinks. It's really nice to drink and if you get tired easily it definitely will give you that bit of a boost you need to help you through the day or night. It is fine to drink the odd time but more than one a day might just be too much to take in.

        INGREDIENTS: Carbonated Water, Sugar, Citric Acid, Taurine (0.4%), Glucuronolactone (0.24%), Acidity Regulator (E331), Colour (Caramel E150d), Flavourings, Caffeine, Preservatives (E202), Inositol, Vitamins (Niacin, Pantothenic Acid, B6, B12), Guarana.

        COST

        If I have tempted you to try Relentless or if you need some energy today then you can buy a 500ml can of Relentless at Tesco for £1.35. Or, if you are near Asda Relentless is currently on rollback for £1 which is a bit better at the minute.

          Advantages

          Disadvantages

          .

          I would say that I am quite a regular drinker of Energy Drinks but it is usually either Asda's or Tesco's own make that I go for. The price of them are good and I feel that they taste just as good as the brand named ones but now and again I reach for a larger can and the 2 larger cans about are this brand and the brand Monster.

          The Relentless brand comes in a few different flavours thesedays. There is the Original one and a few that have Fruit Juices mixed through them. I think I have tried all of them, but think that the Original one is the best one as it is more the flavour that I associate with an Energy Drink and I have found a few of the Fruit ones to taste perhaps that bit Sour in a sense. That's just my view though.

          The tins look ok. The remind me of a tin of Lager with the gold coloured bit at the top and the darker colour on the body of the tin. Depending on the flavour these come in different colours but they all have the kind of Gothic style writing on the side of them.

          The only size this comes in is a 500ml tin. This sounds alright, but it can be a lot of Energy drink to drink at a time. I could see myself on the odd occassion drinking 2 tins of 250ml cans perhaps back to back, but at least the other can stays cool in the fridge, I prefer a drink like this to stay cold, so sipping at this amount isn't going to keep it all that cold.

          You don't get this in a diet form and per 100ml this has 44 calories, so not that great for you.

          This is fizzy enough but doesn't seem to be overly fizzy and I find that if I take a while to drink this tin then it will pretty much be flat by the time I have finished with it.

          This is a good enough Energy drink and if you are looking for a big wake up then this big tin should do the job.

          Advantages

          Disadvantages

          Gives you the kick when its needed

          As stated on the can "Relentless is an energy drink that helps give you the stamina focus and drive you need when you need it". I can vouch for this; it really does give you a kick.

          Relentless is one of the more popular brands of energy drink, along with Red Bull. It comes in a 500ml can, the same sort of size as a can of lager. It costs £1.75 from my local Costcutter, but can often be found on offer in supermarkets for 2 for £2. Comparing this to Red Bull shows that relentless is great value for money, as Red Bull comes in a smaller can, and often costs the same.

          I first started drinking Relentless regularly when my daughter was very young, the sleepless nights were tiring me out and I needed something to give me a kick at around tea time to see me through the rest of the day. Having tried other brands of stimulant drinks, Relentless has shown to be the most effective.

          There is a warning on the can, not suitable for children, pregnant women and those sensitive to caffeine. It contains 58% of the recommended daily allowance of sugar for a typical adult, so very high in sugar content. Not good for your teeth!

          I would recommend this to anyone needing a pick me up, just be careful not to get too addicted to this highly addictive drink! The price does seem quite expensive but not compared to others on the market if you can find it on offer.

            Advantages

            Disadvantages

            excellent drink

            Relentless is my favourite brand of energy drinks. They have a good range of flavours including a new sugar free option, Libertus, which is really tasty, even without the sugar.

            To start with the designs of the cans are eye catching, futuristic, and really draw you to the brand. The design is obviously well thought out. The artwork is very detailed and attractive.

            The price of the drinks can vary from shop to shop. There are often offers for 99p a can, but they can go up to about £1.59. It isnt the cheapest of the drinks but it is still worth it.

            The cans are of a decent size, much bigger than a lot of more expensive energy drinks. They last for a long time and are very refreshing. The caffiene content is also higher than a lot of rival drinks, so it will keep you going for longer.

            The drinks also work well as a mixer with Jager, JD and Vodka.

            A definite favourite :)

            Advantages

            Disadvantages

            A nice drink with an energy kick if you can afford it!

            My husband and I are regular drinkers of energy drinks (me less so at the moment though because I'm pregnant and so cutting down on my caffeine intake) and Relentless is one we particularly like. Neither of us drink alcohol at home so for my husband, a can of Relentless at the end of a day at work is like having a can of beer; he enjoys it for the taste.

            Relentless has been around for a number of years and is one of the many drinks produced by Coca Cola. This isn't obvious when looking at the can; there is no Coca Cola branding on the can, just the name in the small print on the can. The design of the can is very funky with the name of the drink written in a gothic style of font and emits rather a rock and roll feel, leading the customer to feel that they are perhaps living a little bit of a rock and roll lifestyle, yeah!

            The can is about the size of a can of lager and holds 500ml of the drink which is a mixed fruit flavour. The flavour is not unlike that of Red Bull but is more syrupy. When poured out of the can, the drink is a dark yellow with a slightly luminous glow to it which can be a little disconcerting so I tend to keep it in the can so I can't see what it looks like! It is fizzy and refreshing to drink. Although it is syrupy, I don't find it so much so that it's sickly. Personal tastes differ of course!

            It is an energy drink and contains 32mg of caffeine per 100ml of drink and there is a warning on the can to say that pregnant women should consume this as part of a balanced diet. I tend to have only half a can now and again so I don't overdo it on the caffeine. It does provide that hit too, gives the caffeine boost needed so don't drink it before bedtime!

            The one downside of this is the price. There are often deals of 2 for £2 in supermarkets but normally a can costs around £1.35. At our Vue cinema a can costs £2.05 which I find extortionate!

            There are many different flavours of Relentless which have different names such as Inferno and Libertus. Libertus is a new sugar free version which just seems to have appeared in the shops recently. Orange, tropical fruit and berry flavours are available and all very nice! The tropical one is quite nice as it's made up largely of fruit juice.

            It recommends on the can that it is best enjoyed ice cold and I'd agree as once it's been left to sit and get to room temperature, it can have that cat pee smell that some energy drinks seem to give off!!!! Yuck!

            Advantages

            Disadvantages

            Good alternative to Red Bull, more for your money and tastes ok!

            In my opinion Relentless is a pretty sold competitor to Red Bull and I have no gripes with choosing Relentless over Red Bull sometimes. It comes in various flavours much like Monster but tastes alot better. I have tried the original flavour and the "Juiced Energy" flavour which comes in a light green can. The Juiced Energy flavour actually tastes quite fruity and its not a bad taste over all. I'd describe it as a slightly fizzy somewhat citrusy / limey drink.

            Compared to Red Bull you definitley get more for your money where Relentless is concerned and their motif which is across their cans states "No Half Measure" and it couldn't be truer. You get quite a generouus portion for the amount you pay. It also states on the Juiced Energy can that it is 50% juice... although I guarantee the drink is probably still bad for you especially as its made by Coca Cola!

            Relentless, funnily enough is one of the only energy drinks at the moment that does actually seem to get me buzzing and awake... especially after downing a whole can. It can make you a bit twitchy at times and if you are not used to it can even cause heart palpatations according to my friend so its definitley not for the caffeine weak people out there.

            This also goes well with Vodka and ice on a night out and you get alot more than you would mixing it with Red Bull.

            Overall a good alternative to Red Bull.

            Advantages

            Disadvantages

            big can, big kick!

            For an energy drink that's twice the size of Red Bull and the same price you can only laugh at the brand's key tag line - "No half measures". It's almost like a big slap in the face to the competition, but for an energy drink that appeals to extreme sports fanatics, and people with a passion for their craft that's not a bad attitude to take.

            Sure some people will laugh at the size of the can, but you can get 24oz can's of this kind of stuff in America (ROCKSTAR energy drinks for example) so we've still got a long way to go before we catch them up! Personally I feel 24oz's would probably make me achieve some sort of zen like state of super energy, so I think that a single can of Relentless should be enough for now.

            The can is nicely designed and you won't find many drinks these days with huge pulsating heads on their cans. As for whether you can drink a whole double sized energy drink that's another story. I tried, got half way through and failed and that probably means that I'm just not hardcore enough.

            This is a sports drink for groups of professionals, it's the perfect size to share and pass around and it's got the street cred to go with it. It'll also work well with relentless jobs that require constant energy: Truckers and Bouncers up and down the country should take note!

            You might feel that £1.49 is a bit pricey for a can, even though its double the size of a Red Bull can! But you can save yourself a few £££'s if you purchase in bulk, therefore my quest took me to an online source http://www.energyshack.co.uk where you can purchase this stuff and get it delivered straight to your door, saving time and petrol, as it's much easier to stock up on this stuff.

            Disadvantages

            No Half Measures Of Sugar

            This is a review on Relentless, an energy drink manufactured by Coca-Cola Drinks.

            Relentless can be found in almost any supermarket, petrol station or news agents and is sold in a 500ml can. The can is brown in colour with a design in the background and the word Relentless in white written up the can. The slogan 'No Half Measures' is written at the bottom of the can.

            The drink itself is not that far from Red Bull yet for me I find Relentless less medicinal in taste when compared to Red Bull. Relentless is an opaque browny-red drink with a sharp yet refreshing taste which is definately best served cold. The only down side of the taste is that I find it to be a tad too carbonated and if drank quickly will inflict the consumer with bouts of gas, not good if on the way to an interview or to meet your partners parents for the first time.

            The other side to the drink is what is in it. As for most energy drinks, Relentless contains no fats and only a trace of salt but blows the chart with 10.4g of sugar per 100ml concluding in 52g of sugar in the whole can. It also contains 46kCal per 100g which can be expected for an energy drink but can be quite bad for you if you are drinking a few of these a week.

            Ingredients

            Carbonated Water, Sugar, Citric Acid, Taurine (0.4%), Glucuronolactone (0.24%), Acidity Regulator (E331), Colours (Caramel E150d, E104), Flavourings, Preservatives (E202, E211), Caffeine, Inositol, Vitamins (Niacin, Pantothenic Acid, B6, B12), Guarana.

            As mentioned before, Relentless can be purchased in almost any store where drinks are for sale and the prices are as varied as the stored you find them in. If buying from a supermarket you will be looking at paying around £1.25 a can but expect anything up to £1.80 at a petrol station.

            Advantages

            Disadvantages

            I would recommend Relentless over any other stimulant drink: it tastes nice and works!

            Relentless is just one amongst the many, many energy/stimulant drinks out on the market today. However, I would say its only true contender is Red Bull, and only then purely because of Red Bull's hard marketing campaigns. Relentless is different, preferring to mainly sponsor UK sports events and festivals such as Relentless NASS festival and Relentless Boardmasters.

            Relentless is my drink of choice when I require energy. I love the taste and it seems to be the only stimulant drink which works on me any more. (I'm a student, we need a lot of this kind of thing during exams and essays).
            Relentless is not the cheapest drink on the market but, as I said, I feel it is the best value for money. The 500ml cans will last you a while because they contain so much caffeine: 32mg/100ml. Even so, in places you can get a 4-pack of Relentless for £3.95. Not bad at all considering you can pay up to £2 for a single can.

            I like the packaging as well, and the way unknowing people judge me because it sort of looks like lager!

            The only reason I'm giving Relentless 4 stars instead of 5 is because it does tend to mess up my sleeping patterns and is highly addictive.

              Quite a nice tasting energy drink which comes in a large can

              I've tried pretty much all energy drinks out in the UK, and being a student I spend a decent few pounds on buying these drinks for the weekend or when I've got a crazy assignment in for the next day as it keeps me sharp and well, I like the taste. They are also brilliant after the gym, to top up the energy and wake you up a little (NOT during the exercise).

              Price

              Relentless has to be one of the better energy drinks I've tried in a long time, not only is it one of the few drinks that comes in a 500ml can, but is also great value for money with all considered; Red Bull costs £1.30 for an average can of 250ml, see the massive difference, of course not forget Tesco Kick or Red Devil, but I found they don't have the same effect or "strength" as Relentless, or variety of flavours for that matter.

              Effect

              After drinking the whole can of Relentless over a 10 minute period, I usually get a "high" and can concentrate on things better and am really alert, hence it's great for doing assignments, but unfortunately it only lasts for a few minutes to an hour before you have a "crash" and being to feel tired and your concentration levels go way off. I found that drinking a lot of water (3-5 glasses) will restore you original state, or you can crack open another can and get the same effect for another few minutes. But there is a down side to it, since the drink is caffeine rich, it has a bladder "weakening" effect and may course you to go to the toilet much more often or worst (last episode of InBetweeners Season 2 for better explanation).

              Taste

              First time I tried Relentless Origin, I found that it strongly resembled the Tesco Kick taste, the so called Mixed Fruit taste, however wasn't as strong as Relentless. Relentless also comes in different flavours so you have a little bit of variety.

              Health Risks/Effects

              Like the warning on the can says, this drink is high in caffeine and contains Taurine, so if you're sensitive to either of them, avoid. Also because of the high caffeine levels young children should not really drink this, and the drink is sometimes not sold to under 16's, I in fact got asked how old I was once or twice before I was sold it. Also pregnant women should avoid it. Like I said above, consumption in large amounts will have a negative effect on your bladder by weakening it, meaning you have to go a lot more often or if you consume the drink one after another, your stomach will not be pleased.

              Conclusion

              Overall, this drink tastes pretty good and does what it is meant to by giving you a sort alert level, however the crash which will eventually come is the exact opposite. The price is quite good too, I buy a 4 pack for about £4 in Tesco on a monthly basis and keep it in the fridge for when I need it, individual cans cost around £1.30 to £1.60 depending on the flavour in Tesco. Apart from the slight health issues with continuous consumption, this drink is great.

                Disadvantages

                Only The Original Is Worth Drinking

                In my opinion, Relentless is the tastiest of all the energy drinks. I have tried quite a few differents ones - Lucozade, Monster, Mountain Dew, Red Bull, Red Rooster, Boost, and to be perfectly honest I feel that they all taste the same, bland, tasteless, not really something I'd drink just as a drink.

                I find that Relentless has a much sweeter taste than the others, and is much easier to drink. The original and flavoured versions are actually quite nice to drink. Its also quite good to use as a mixer, maybe unhealthy, but it's a lot tastier than using coke or pepsi (which I hate anyway). And it kind of does it's job, I felt a lot more alert afterwards and I felt much more awake, but not as if I had any more energy.

                Despite the original versions of Relentless being nice, the shot is a bit of a let down - I didn't really feel any kind of energy rush whatsoever, maybe the same as with the normal relentless - a bit more awake, but not particularly different.

                As well as the shot, there is also the 50% juice version, which is absolutely disgusting, it's a lot like if you water down actual juice, it's not fizzy, not tasty, and doesn't do anything by the way of increasing your energy.

                The brand relentless also sponsors a lot of extreme events, and they have a lot of festivals, which I think is kind of cool as well.

                So, I would definitely recommend the original or flavoured versions of this drink, they are the tastiest versions of energy drinks you can find, but I would say stay clear of the juiced version.
