What Is Phen24?

Billed as “your 24-hour weight loss solution,” Phen24 is an all-natural supplement that is designed to promote weight loss and fat burning around the clock. Unlike the vast majority of weight-loss supplements on the market today, it consists of two products-a daytime version and a nighttime version — which means that it has two unique formulas. A single 30-day supply includes daytime and nighttime formulas, so there is no need to buy separate products. Three pills — one daytime pill and two nighttime pills — must be taken daily. This review examines various aspects of this supplement, including its active ingredients, its ease of use, its effectiveness, its affordability and more.

The name of this supplement reflects the fact that its daytime formula contains Phenylalanine, an essential amino acid that helps to suppress the appetite and, in turn, assists in weight loss. The “24” in the name, of course, refers to the fact that this supplement works 24 hours per day. Most weight-loss supplements only work by day. Overnight, the body may store fat, which negates the positive benefits of daytime supplement usage. This supplement aims to solve this by providing a nighttime supplement as well. The manufacturer states that because it works around the clock, this supplement is more effective than traditional weight-loss and fat-burning supplements.

On the company’s website, the manufacturer acknowledges that a single pill cannot create a “dream body.” As indicated in the instructions, this supplement works best when it is combined with regular exercise and a healthy diet.



Phen24 is produced by Wolfson Berg Limited. This company has a positive reputation in the industry. It is best known for relying solely on 100-percent pharmaceutical-grade ingredients, which does not mean that these pills contain synthetic ingredients. On the contrary, this supplement consists of natural ingredients that are not known to cause any serious, negative side effects.

Consumers who are interested in trying this supplement can rest assured that the manufacturer of this product has a good reputation. A quick online search revealed no negative comments or reports about Wolfson Berg Limited, which suggests that this product should be of excellent quality.


How Phen24 Works?

As a 24-hour weight-loss solution, this supplement works around the clock to maintain ongoing fat burning and weight loss. Supplements that only work during the day are often less effective due to the fact that while sleeping, the body metabolizes carbohydrates less effectively. To make matters worse, insulin production increases, and more fat is stored. At the same time, levels of cortisol, a stress hormone that is known to trigger increased levels of fat in the body, increase dramatically.

All of this means that overnight, whatever positive benefits that were derived from the daytime supplement are largely canceled out. This supplement is different because it includes a nighttime formula that is specifically designed to counteract the negative effects that sleep can have on the metabolism. This helps to prevent an increase in levels of the hunger hormone ghrelin, which causes people to feel hungry throughout the day.

By day, this supplement provides these benefits:

  • Increased energy;
  • Increased metabolism;
  • Increased calorie burning.

By night, this supplement provides these benefits:

  • Improved sleep;
  • Increased nighttime metabolism;
  • Reduced nighttime cravings.

The positive benefits of the daytime formula dovetail well with the positive benefits of the nighttime formula. This is why the two must be taken consistently. If only one or the other is used, the positive benefits of each are reduced. Therefore, those who want to enjoy the best results from this supplement must commit themselves to taking the supplement once in the morning and once in the evening.

Per the manufacturer, one daytime pill should be taken each morning with breakfast. Two nighttime pills should be taken 15 minutes before the evening meal along with one to two eight-ounce glasses of water.


Ingredients of Phen24

Because this supplement includes daytime and nighttime formulas, there are two separate lists of ingredients. First, let’s look at the ingredients that are found in the daytime formula and their purported effects:

Caffeine – In addition to increasing focus and alertness and reducing fatigue, caffeine is believed to stimulate a process called thermogenesis, which boosts internal body temperatures and, in turn, stimulates the metabolism and reduces appetite.

Guarana Extract – This plant contains one of the highest concentrations of caffeine, with anywhere from 3.6 to 5.8 percent per serving. Coffee contains around 2 percent of caffeine. This additional boost is believed to bolster exercise-related fat loss.

Cayenne Powder – Spicy foods have been shown to increase body temperature, which causes the body to use more energy to stay cool. Studies have shown that using ingredients like Cayenne Pepper daily may boost metabolism by 25 percent.

Phenylalanine – Phenylalanine is an essential amino acid, which means that it can’t be produced by the body. It stimulates the release of cholecystokinin, an intestinal hormone that triggers a feeling of fullness and satiety.

Iodine – Added to salt for decades, iodine is best known for improving thyroid functioning. Because it bolsters functioning of this important organ, it may increase metabolism too.

Manganese – Manganese also boosts thyroid function. At the same time, it helps to regulate the body’s ability to metabolize carbohydrates and fats. Because it regulates blood sugar, it may help ward off cravings too.

Zinc Citrate – In conjunction with vitamins A and E, Zinc Citrate works to produce hormone that are secreted by the thyroid. It assists in digestion too, ensuring that less food is stored as fat.

Copper Sulphate – This ingredient assists in oxidative reactions that work to convert fats into energy.

There are more ingredients in the nighttime formula. They are:

Glucomannan – Billed as Phen24’s “key ingredient,” Glucomannan, a dietary fiber, helps extend feelings of fullness. It does this by absorbing water. As a result, cravings are supposed to be reduced.

Chromium Picolinate – This ingredient is used in the nighttime formula because it helps to move glucose around the body. Glucose helps to turn macronutrients into energy, so it helps burn fat, build muscle and effectively metabolize carbohydrates.

Biotin – This ingredient, which is best known for promoting healthy hair and nails, also helps to prevent fat storage in the body.

Choline Bitartrate – It’s easy to see why this ingredient is included, as it performs a laundry list of functions. These include regulating cholesterol, regulating gallbladder, kidney and liver functioning, fighting fatigue and controlling fat storage.

Molybdenum – Molybdenum assists in energy production through the use of broken-down macronutrients. It also promotes strong, healthy muscles, aids in digestion and regulates heart health.

Pantothenic Acid – Also known as Vitamin B5, Pantothenic Acid helps to metabolize toxins out of the body and is a key component in metabolizing food into energy.

Thiamine – Also known as Vitamin B1, Thiamine helps to effectively convert food into energy.

Pyridoxine HCL – Also known as Vitamin B6, this ingredient is involved in more than 100 crucial enzyme reactions in the body.

Green Tea Extract – Because it contains Caffeine, Green Tea Extract helps to boost thermogenesis. It also enhances the effectiveness of fat-burning hormones.

Ascorbic Acid – A form of Vitamin C, Ascorbic Acid aids in muscle recovery, which comes in handy when you have a lot of extra energy for exercising during the day.

Griffonia Extract – This ingredient is included to ensure a restful night’s sleep. It aids in healthy sleep by helping to create 5-HTP, which produces feelings of relaxation and calmness.

Hops Extract – Hops have long been used to naturally treat insomnia. Hops Extract therefore aids in sleep, and it has the added bonus of reducing fat—
especially around the midsection.



One of the main advantages of this supplement is the fact that it promotes healthy weight loss not just during the day but overnight as well. No other product on the market right now offers a solution that covers 24 hours of the day, so this is a major selling point. As long as this product is used as directed, it prompts the body to burn calories and fat more quickly and efficiently. When combined with a healthy diet and regular exercise, it gives the body the boost that it needs to drop pounds effectively.

Another advantage of this supplement is the fact that it contains no major stimulants. While the daytime formula contains caffeine, it is in low enough doses to provide a bit of a boost without making you feel wired or on edge. There is no worry about being too revved up to get a good night’s sleep, either, because the daytime pill is taken first thing in the morning. The nighttime formula contains ingredients that make you relaxed and ready for bed, so this supplement won’t affect the sleep cycle—
at least not negatively.

This product is backed up by a generous money-back guarantee. You have 67 days from the date of receipt to return any unused portions for a full refund. Therefore, there is no real risk in giving this supplement a try. The worst-case scenario is that it doesn’t work well enough, and then a refund is issued.



The manufacturer of Phen24 does not list any major certificates or certifications on the company website. This is not to say that no certificates or certifications have been issued, however. Because it is still relatively new to the market, enough time may not have passed for such credentials to have been awarded. The company does hold SSL security certificates for online sales processing, which is reassuring. These certificates can easily be confirmed through any standard web browser. They do expire, however, so consumers should do their own research before completing purchases through the website.



Testimonials and other reviews regarding this supplement have been overwhelmingly positive. To flesh out this professional review, a handful of testimonials from actual customers are provided below.

Every time I’ve tried losing weight, my efforts have been ruined due to nighttime binge-eating. For some reason, my natural tendency is to want to eat a lot after the sun goes down. By day, I would adhere to a strict diet and get plenty of exercise. When evening struck, though, I’d head right for the fridge — and all of my effort would go down the drain. When I heard about Phen24, I was intrigued because it addresses nighttime cravings as well. I figured it wouldn’t hurt to try, so I ordered a one-month supply. Even before the month was over, I’d seen a major improvement. I went ahead and ordered more, and I am happy to say that I’ve lost 15 pounds since starting on this product a few months ago.

– Michele T., Los Angeles, CA

Through the years, I’ve tried every supplement under the sun to try and lose those last few stubborn pounds. None of them worked. If anything, they made matters worse. The most aggravating thing was taking supplements that were loaded with stimulants. While they helped me lose weight, they also made me an insomniac. My experience with Phen24 has been mostly positive simply because it doesn’t interfere with my sleep cycle. If anything, it seems to help me sleep better. However, I haven’t lost quite as much weight as I had hoped to by this point. I understand that my diet and exercise matter too, so I will continue to be strict about them and see how it goes.

– Nancy C., Miami, FL

A few years back, I finally had a moment of clarity and realized that I needed to get serious about diet and exercise if I wanted to avoid becoming morbidly obese. In the beginning, the weight loss was quite dramatic. I was thrilled. Things tapered off over time, though, and I still had a lot more weight to lose. A friend recommended Phen24, so I decided to give it a whirl. For me, it’s been nothing short of amazing. My workouts seems to give me even better results, and I am sleeping more soundly than ever. I never feel wired or overly hungry. Its effects seem pretty subtle at first, but when I look at my weight loss progress, it definitely spiked when I started taking this supplement. I can’t recommend it highly enough.

– Chad A., Philadelphia, PA


Awards & Media Coverage

Unlike many weight-loss supplements, which are often endorsed by major celebrities and featured on popular television shows, this supplement thus far doesn’t appear to have received much media coverage or any awards. Based on the positive reviews that are out there, however, it probably won’t be too long before the media gets wind of this product and starts featuring it regularly. Given its uniqueness, it is sure to win awards before too long as well.


Money-back Guarantee

This product is backed up by a very generous money-back guarantee. Those who order an initial supply of Phen24 and aren’t happy with it can easily send back the unused portion for a full refund minus shipping charges.

Most supplements today are backed up by 30-day money-back guarantees. This supplement offers a very generous 60-day money-back guarantee, but it’s actually 67 days according to the website. Upon receipt of the product, customers have 67 days to return it to the manufacturer. As long as it is received within the 67-day window, a full refund will be issued minus shipping costs. Because the product is shipped to the customer for free, the customer only has to pay for the cost to ship the unused portion back to the manufacturer. In most cases, this cost will be minimal, so the most that someone stands to lose by trying Phen24 is maybe $10 to $20.

After this product has gained more recognition, the manufacturer could very well decide to offer an even more generous guarantee or discounted pricing. It would certainly help to give this supplement a competitive edge — especially when combined with the money-back guarantee.



A very generous shipping policy is offered with Phen24. First, the manufacturer ships orders very quickly. If an order is placed on a business day, it typically ships that very day. Major shipping carriers are used, so orders usually arrive at customers’ homes within a few days. Of course, this depends on the customer’s location. Since this product is shipped worldwide, international customers may have to wait a bit longer.

Free shipping is provided on all orders, which is very generous. However, one drawback to this is the fact that customers can’t opt for faster shipping. Therefore, when ordering a new supply, it is important to make sure to order it early enough. Otherwise, the replenishment may not arrive before the previous supply runs out.

The fact that this supplement is shipped worldwide is nice. What’s even nicer is that international customers don’t pay for shipping, either. This definitely gives this product a significant edge over competing products, as most supplements are only shipped for free within the United States.

In the event that the product is unsatisfactory, the customer must pay to ship it back to the manufacturer. Upon receipt, the manufacturer issues a full refund. However, they will not refund the cost of shipping the product back, so that is one expense that must be absorbed by the customer. This is something that may come as a surprise to some customers, who may be angry about having to pay to ship back something that didn’t work for them. When compared with similar products, though, this is still a fairly good deal.


Customer Support

It’s important to research about a manufacturer’s level of customer support before buying products from them. Customer support for Phen24 is fairly middle of the road. The company does offer live chat on its main website, which is useful in many ways. However, many folks prefer dealing with issues over the phone. There is a toll-free number available for customer support, so there is a way to resolve issues over the phone. This is surprising, as some supplement companies do not have 24/7 telephone support.

There is also a contact form available on the website. This would be a nice option for times when customers have questions that aren’t urgent. Similarly, there is a customer support page on the website.

One way in which Phen24 excels in terms of customer care is through its exceptional return policy, which offers a much longer window than most competitors. The website also includes a fairly detailed FAQ, and it seems to cover the most common concerns that customers run across while using Phen24. The contact form is maybe used for these returns and the FAQ page looks like a fresh one.


Safe & Secure Checkout

When it comes to actually purchasing this supplement, the news is all positive. The checkout process is as safe and streamlined as can be. Adding products to the shopping cart is easy, and navigating through the checkout process is intuitive. Every step of the way, transactions are protected by SSL, or secure socket layer, encryption. This means that in the event that someone tried to hack into the computer or server during such a transaction, they would be unable to get any sensitive financial information. That’s because SSL 248-bit encryption, which is what is used in this instance, takes such information and jumbles it up before sending it. Therefore, even if it is intercepted somehow, it will be useless to whoever gets it.

No complaints have been filed against the company for issues regarding security. The BBB hasn’t received or published any reports regarding insecure payment processing, so it appears that consumers can safely provide their financial information in order to buy Phen24. However, it is still important for customers to check their credit card and bank statements often. The sooner suspicious activity is detected and handled, the better the outcome is likely to be.

The checkout process is fast and secure, and email confirmations are sent. That way, customers know that their orders have been received and processed and that they will be receiving their supply of this supplement in short order. Another way in which consumers are protected financially is through the 60-day money-back guarantee, which applies to all orders.



For the purposes of this review, we will consider the list price of this supplement. The manufacturer describes it as the “retail price.” Discounts are offered on bulk orders, but better deals may be had elsewhere.

A single box of Phen24, which includes enough daytime and nighttime supplements for 30 full days and nights, retails at $64.99. At first glance, this may seem steep. However, you’re essentially getting two types of pills for the price of one. Also, suppliers may offer discounts off of list, or retail, price.

When purchasing two bottles of this supplement, which equals a two-month supply, customers are charged a list price of $129.99. This represents a bit of a discount off of the list price for a single bottle. Again, however, it is often possible to find two bottles sold for a lower price.

Finally, when two boxes of this supplement are ordered, three additional boxes are included for free. This means that it’s possible to get a five-month supply when buying just two months’ worth. In this case, the list price for buying two boxes plus three free extras is $194.99. This price is often discounted, however, so it can actually be fairly affordable to buy an entire five-month supply of this supplement. When comparing the price of this product to that of others, it’s important to remember that this supplement works 24/7 while most others only work during the day. Therefore, it may actually be more competitively priced than many others.


  • Works around the clock, so it is possible to keep burning calories and fat even while asleep.
  • All-natural ingredients facilitate healthy weight loss when combined with regular exercise and a healthy diet.
  • Generous money-back guarantee.
  • Delivers many positive benefits, including reduced nighttime cravings, improved sleep, improved energy, faster metabolism and more.


  • Three pills must be taken each day — one in the morning, and then two at night — which may be cumbersome for some.
  • Social media websites were not extensively used by this merchant.
  • Pills come in blister packets that are often difficult to open, which can be frustrating.
  • Because both types of pills must be taken for this supplement to be effective, people who would rather not take supplements at certain times of day may be disappointed.


Summary: Phen24 is a fat burning weight-loss product supplement that is sold in boxes that contain both daytime and nighttime supplements. For this reason, it is designed to facilitate weight loss and fat burning not just by day but by night too. In addition to promoting weight loss overnight, this product contains no stimulants and is designed to facilitate better sleep as well. Both its daytime and nighttime formulas contain all-natural ingredients.
