- Contains some effective fat burners
- If the doses are right, then it will definitely increase fat loss

- No dose information given whatsoever
- No idea how much caffeine we get
- Phenylalanine a potential 'filler'
Phen24 contains some excellent fat burning ingredients. There are plenty of positive Phen24 reviews out there too. But we can’t possibly recommend a fat burner to our readers when we don’t know the exact ingredient servings. There are some ingredients in Phen24 that don’t really contribute to greater fat loss, enhanced athletic performance, or better recovery. These could make up most of the formula. There are better fat burners on the market today for sure.
Our Phen24 Review
Phen24 is a natural fat burner. It is sold exclusively online. You’ve probably seen this stuff advertised on some of the major bodybuilding forums. If you’ve spent any time reading amateur bodybuilding and fitness blogs, we guarantee that you’ve seen Phen24 banner ads. Phen24 seems to be particularly popular in the US; from what we can tell, the vast majority of sales come from the UK. It is a UK-made product after all!
So what does Phen24 claim to do exactly? Who is it for?
The idea behind Phen24 is simple – “weight loss is a 24-hour process”. The Phen24 formula is split into two parts; a day formula and a night formula. According to the official website, Phen24 supports round-the-clock weight loss by enhancing your diet, training, and sleep.
This makes perfect sense. It is during sleep that we recover, it’s during sleep that your muscles grow, and it is during the early hours of the morning when your growth hormone levels spike (meaning the greatest possible period of fat loss).
The website claims that Phen24 delivers the following benefits:
- Increased metabolism
- Increased energy levels
- Greater caloric expenditure at rest
- Reduced food cravings in the evening
- Enhanced sleep quality
This is a fantastic list of benefits. Assuming that Phen24 can actually do all of this, then it will be an extremely effective fat burning supplement.
But we don’t make assumptions.
Does Phen24 really work?
Is it safe? Will it cause side effects?
How does Phen24 compare to the best fat burners on sale today?
In our detailed Phen24 review we answer all of these questions and more. Check out the review below and if you have any questions, let us know in the comments section. Have you used Phen24? Did it work for you? Share your experiences with other readers in the comments!
Let’s take a look at the Phen24 formula to see what this fat loss supplement can really do. Here is the Phen24 ingredients list as it is shown on the website:
The first thing most of you will notice is the lack of dosing information here. Phen24 is a proprietary blend. We’ve searched everywhere online, and we cannot find any reliable details about the formula.
We are not told how much of each ingredient is used in Phen24.
Worse still, we aren’t even told a total serving size for the formula!
This is highly unusual – even low quality fat burners tell us a total blend size.
There could be any amount of any of the ingredients in Phen24 – so long as it fits in the capsule that is.
This is a MASSIVE problem!
Phen24 contains some great natural fat burners, but it also contains ingredients that don’t do much for weight loss.
Even worse, Phen24 contains caffeine. How much caffeine is a complete mystery.
We cannot even begin to guess how much caffeine is in Phen24 because we don’t have a total blend serving size. There could be an enormous, potentially lethal dose of caffeine in each serving of Phen24 for all we know.
Is this likely? No.
But it is possible. That’s enough to put us off this fat burner completely.
Let’s go through these points in more detail.
Main Weakness – Proprietary Blend
We can’t stand it when manufacturers hide their formulas behind proprietary blends.
There is no good reason to keep your ingredient servings a secret.
Formula theft doesn’t happen. There is nothing mysterious about the ingredients in Phen24 – we know how they work and how they should be dosed for optimal results.
In other words, there’s no special intellectual property to steal.
Most other supplement manufacturers clearly realise this; they all disclose their formulas in full on their websites and their bottles.
So why doesn’t Phen24?
Do the manufacturers think someone will steal their amazing formula? That’s doubtful.
Do they have something to hide? Probably.
Manufacturers routinely use proprietary blends so that they can stuff their formulas with ‘filler’ ingredients. In other words, they bulk out their formulas with the cheapest, least effective ingredients and they prevent anyone from noticing by hiding the serving sizes.
Formula stuffing keeps costs down and profits up.
But you get left with a fat burner that is 90% useless rubbish and about 10% effective ingredients.
We don’t know for certain that Phen24 is doing this. It might be that the guys behind Phen24 are genuinely afraid of formula theft. But even if that is the case, we don’t care. We’re not here to make allowances for the naivety or cowardice of supplement manufacturers.
Other fat burners use their generous serving sizes as a big selling point. Some brands are actually proud of their formulas – they can’t wait for you to see the massive doses of their potent ingredients.
Phen24 isn’t so keen for you to see its serving sizes.
Think about that before you buy!
Major Weakness – Ineffective Ingredients
Phen24 contains some ingredients that don’t actually contribute to greater weight loss, better sleep quality, or enhanced athletic performance.
In fact, some of the ingredients don’t really do anything at all!
For example, Phen24 Day contains an unknown quantity of phenylalanine.
Phenylalanine is a non-essential amino acid. This means that you don’t need to consume any phenylalanine; your body can make it as and when it needs to.
Phenylalanine is a proteinogenic amino acid. This means that it is incorporated into larger proteins, which are then used to make new muscle tissue. However, unlike Leucine, Isoleucine or Valine, it is not known to stimulate protein synthesis directly in any meaningful way.
Phenylalanine’s role in the body is not properly understood. It is converted into other useful amino acids – such as Tyrosine – but there doesn’t seem to be any major direct effects from phenylalanine supplementation. It has been said to be an antidepressant, a treatment for skin disorders, and a pain reliever. No evidence exists for any of these claims (source).
One thing seems clear to us; there is no good clinical evidence showing that phenylalanine promotes weight loss in any way, shape, or form. It is just a non-essential amino acid found in many plant and animal foods.
Phen24 Day could be 99% phenylalanine for all we know. That is not the kind of gamble we’re willing to take; certainly not for £49.99!
The same problem can be seen with the Phen24 Night formula too. The Phen24 Night formula contains ingredients which might be great for overall health and performance, but they don’t do a thing for sleep quality or for fat metabolism.
For example, look at Ascorbic Acid (Vitamin C).
Supplementing with Vitamin C is a great way to promote overall good health and immune system function.
If you’re training hard and dieting, you are at an increased risk of getting sick. Supplementing with Vitamin C could be said to be an effective way to optimize your training – you can’t train properly if you’re sick!
But this is still not something we want to get from a fat burner, especially not one that could be 95% Vitamin C, and especially one that costs £49.99 per month!
Vitamin C does not have any direct effect on fat metabolism, athletic performance, or sleep quality.
You can make a case for it being an indirect fat burner, but then we could say the same for just about every substance in every fat burner currently on the market.
When we are buying premium fat burners or weight loss supplements like Phen24, we only want ingredients that actually help us achieve our goals. That is, we only want substances that will do the benefits listed on the product’s website.
We don’t want substances that the manufacturer thinks might be useful or vaguely beneficial for your health.
Again, Phen24 could be 95% Vitamin C for all we know. Pehn24 could effectively be a very expensive Vitamin C supplement. This is not acceptable for a weight loss supplement which claims to be professional quality.
Pricing – How Much Is Phen24?
Phen24 is massively over-priced in our opinion.
A single bottle costs £49.99.
That works out at £1.66 per day for a full month’s supply of Phen24.
Now, that is not too expensive for a high quality fat burner. But it is too expensive for Phen24.
£1.66 per day is the same price as other fat burners on the market right now. But these products offer total formula transparency; they actually tell you how much of each ingredient you get per serving!
On top of that, there are fat burners on offer for the same price which don’t contain any potential filler ingredients whatsoever.
The cost of Phen24 does come down a lot when you buy multiple bottles.
Buying 2 boxes will get you a third for free. A 2+1 box deal costs £99.99, or just £1.11 per day.
If you buy 3 boxes of Phen24, you get another 2 boxes for free! This deal costs £149.99.
So £149.99 for 5 boxes works out at £30 per box, or £1 per day.
This is considerably cheaper than most fat burners on the market today. However, we think there is a good reason for this; Phen24 is probably mostly ‘filler’ ingredients!
Phen24 Side Effects – What Are The Risks?
In our opinion Phen24 poses unreasonable side effect risks. We DO NOT recommend using this fat burner. It doesn’t matter how experienced you are with weight loss supplements, or supplements in general.
Knowing what we know about the formula (or rather what we don’t know), we think using Phen24 comes with far greater risks than potential rewards.
The main danger is the fact that we have absolutely no idea how much caffeine Phen24 contains.
Phen24 Day actually contains two different sources of caffeine.
It contains regular, pure caffeine. We don’t know how much caffeine, but we know that it contains some.
It also contains Guarana Extract. Guarana is used for its caffeine content. We don’t know why manufacturers use Guarana instead of caffeine. We’re only interested in the caffeine! The rest of the guarana is just useless plant material!
We definitely wouldn’t use both caffeine and Guarana – that would be like using EGCG and powdered green tea. JUST GIVE US THE USEFUL STUFF & KEEP THE PLANT MATTER!
In any case, we have two different lots of caffeine in Phen24 Day, and we have no clue how much we get of either one.
We don’t need to tell you why this is a problem.
Caffeine is an incredibly powerful stimulant. Consuming large amounts of caffeine produces side effects in pretty much everybody.
It doesn’t matter how good your tolerance is, or how much caffeine you’re used to consuming. If you consume over a certain amount of caffeine, you will experience side effects.
For most people, 150mg in a single serving is more than enough to cause significant side effects. For some context, your average single shot of espresso contains about 80mg of caffeine. Most people experience noticeable adverse effects from 2 shots of espresso consumed in quick succession.
More than 250mg in a single serving will cause serious side effects in almost everybody.
Anything more than 300mg over the course of a day is also going to cause significant side effects in practically everybody. These side effects will include:
- Elevated heart rate
- Heart palpitations
We have absolutely no idea how much caffeine is in each serving of Phen24.
It could be 1mg.
It could be 1g – an absurdly dangerous amount to consume.
We doubt Phen24 contains that much caffeine, but the point is that we don’t know for sure. Any kind of uncertainty is not a good thing when we’re talking about adverse effects and health risks.
For us, it is unreasonable for Phen24 to ask us to take this kind of risk. We don’t care what Phen24’s manufacturer says. We only care about what we know.
You need to carefully calculate your existing caffeine intake before using Phen24. Pre-workouts, coffee, tea; it all counts. Work our how much you’re currently consuming and decide if you can realistically afford to add in any extra caffeine from supplements.
You also need to think about whether or not you are comfortable taking a completely unknown quantity of caffeine. We think this is an extremely bad idea.
We do not consider Phen24 a safe fat burner.
Not at all.
If you want a weight loss supplement that you don’t have to be constantly worried about, look for a fat burner that lists each ingredient’s serving size on the label.
Please remember the following facts while reading our supplement reviews:
- We are not doctors
- This is not medical advice
All we are doing here is highlighting the most obvious risk factors according to our research and experience. We are not being exhaustive – there are other side effect risks with Phen24, but we have focused on the most serious here. We don’t know you or your medical circumstances. If you have any concerns whatsoever, talk to your regular GP before you use any fat burners.
You must always do your own research and get proper medical advice from a qualified professional before using any weight loss supplements. We do not think Phen24 is safe. Not even close.
If you experience any side effects while using Phen24, please cease use immediately and seek medical attention.
Phen24 Review Summary – Is It A Good Weight Loss Stack?
Phen24 is one of the top selling weight loss supplements in the UK. It has been for many years now. Despite being a little old, Phen24 remains one of the most talked-about and widely-used fat burners in the UK, EU, USA, Australia, and Canada.
We have absolutely no idea how it managed to get so popular in the first place.
The Phen24 formula is absolutely terrible.
It isn’t that the ingredients are bad.
It’s that we aren’t given any information whatsoever regarding the doses. We don’t know what the total serving size is, let alone the individual ingredient serving sizes.
We advise our readers to avoid supplements when they use proprietary blends – when manufacturers just give you a total serving size and not the individual ingredient servings. Phen24 doesn’t even give you a total serving value, so we can’t even put an upper limit on what the doses might be!
This is totally unacceptable. Prop blends always mean you’re being ripped off, and Phen24 is even worse than a standard proprietary blend!
The fact that Phen24 contains a completely unknown amount of caffeine means there are serious side effect risks to using this fat burner.
This is such a shame. There are some great natural fat burners in Phen24. If Phen24 contained just these ingredients – and told us how much – then it would probably be a good weight loss stack.
As it stands, we cannot recommend Phen24 to anybody. We actually can’t advise you strongly enough to stay away from Phen24, at least until the manufacturer decides to reveal the full formula specs.
If you want some help shedding excess fat in time for a fight, a bodybuilding contest, or a powerlifting meet, then use a professional, high-quality fat burner with a transparent formula. Phen24 stinks of scam to us!
How To Take Phen24
According to the manufacturer’s instructions, you should take 1 capsule of Phen24 Day with your breakfast. You should then take 2 capsules of Phen24 Night with your evening meal and 1-2 glasses of water.
Where To Buy Phen24
Phen24 is sold exclusively through the official online stores. Visit Phen24(dot)co.uk to learn more. Be careful when buying Phen24 from anywhere else. These are likely people who have bought Phen24 from the online store and are re-selling it at an inflated price. As far as we know, third parties are not licensed to sell Phen24.
Phen24 or Instant Knockout – Which Is Best?
In our opinion, this is a no-brainer. Phen24 is a similar price to Instant Knockout. Yet Instant Knockout has a fully transparent formula. Unlike Phen24, it contains no waste, no fillers, and no potentially dangerous stimulant doses – just good servings of proven, effective fat burners. It blows Phen24 out the water.
