Phen24 Review: Does It Really Work Around the Clock?

Phen24 Reviews, Results, Benefits and Side Effects

Phen24 is a unique new weight loss supplement system that’s been raising quite a few eyebrows lately. The thing that makes these weight loss pills so different from nearly every other product available on the market is the fact that it’s split into two different components: one supplement is designed for daytime use, and the other is for designed to be taken at night.

The purpose for including two different types of supplements is so you can attack your weight loss around the clock, day and night, 24 hours a day – hence the name Phen24. Phen24 claims to be able to quickly and easily help you lose weight and feel better, especially when combined with a sensible diet and regular exercise.

Phen24 is manufactured by Wolfson Berg Ltd., a company specializing in dietary supplements with over thirty years’ experience and clinical research behind them. Primarily focused in the research, development, and distribution of high quality nutraceuticals, the company oversees over 100 supplement brands to consumers around the world.

The main benefits of using daytime Phen24 pills is that they produce quick weight loss by revving up your metabolism, increasing energy levels, suppressing the appetite, and enhancing how your body processes food overall. This is especially true when taken along with regular exercise and a healthy diet – but I think we all probably know that by now.

The nighttime pills encourage a deeper, more restful sleep, which is not only vital for weight loss, but for good fitness overall. It’s no secret that getting proper sleep is a crucial necessity for maintaining health and wellness. Because the Phen24 nighttime formula helps to speed up some of your body’s normal nighttime processes, your overall weight loss efforts get magnified as a result.

Also, all ingredients used in Phen24 are 100% natural and have been scientifically proven to encourage healthy weight loss.


How Does Phen24 Work?

Phen24 works by triggering the body’s enzymes and internal processes that regulate fat loss around the clock. Research shows that poor or inadequate sleep may play a major part in weight gain and cravings. (1) By enhancing both daytime and nighttime metabolic activity with a blend of natural components linked to energy levels and weight loss, Phen24’s formula is scientifically designed to give you the best bang for your buck when it comes to your weight loss results.

Taking the daytime pill increases your metabolism and improves energy levels, helping you feel motivated to exercise and just get through the day without the urge to snack constantly. Taking the nighttime pill produces a feeling of relaxation and encourages deep sleep, while also increasing your metabolism and reducing any cravings you might have for midnight snacks.

Together, these two supplements combine to help get your body primed, energized, and ready to burn fat over the course of 24 hours.

The driving principle behind Phen24 is the idea that successful weight loss is best achieved over a full 24 hour period, since even while you’re sleeping you’re burning calories. Phen24’s nighttime pills increase that process by helping burn those calories in a quicker and more efficient way, allowing you to experience greater weight loss results in a shorter period of time.


As stated, this product comes with both daytime and nighttime supplements in order to target the body’s metabolic processes differently. Not surprisingly, the ingredients found in each of them are completely different.

One thing’s for certain though, it’s obvious that Phen24 has put far more emphasis in the design and amount of ingredients found in the night pills compared to the day pills. That said, I’m not implying that the day pills are any less effective, just that the company understands the importance of nighttime weight loss, and the general lack of solutions for nighttime weight loss products in the diet supplement industry.

The Day supplement ingredients include:

Guarana seeds on white background.

Guarana extract

Guarana is one of the highest plant-based sources of caffeine, which is a powerful effect on metabolic rate (see caffeine, below). Guarana is commonly found in diet pills, energy drinks, and workout supplements. This supplement has been shown to especially improve exercise-related fat loss. (2)

Cayenne pepper and powder on white background.

Cayenne powder

Consuming spicy foods can increase your body’s core temperature, encouraging weight loss. Cayenne can help to significantly increase your metabolic rate. Cayenne is also good for improving digestion and reducing high blood pressure.

Chemical formula for caffeine on white background.Caffeine

Caffeine has long been known for its ability to reduce fatigue, as well as encouraging  thermogenesis, which is the process that involves increasing your body’s core temperature, thereby burning fat and calories, and helping you lose weight. (3)

Copper sulfate crystals on white background.Copper Sulphate

Copper sulphate is a mineral that’ used for fat oxidation, which is the process that converts fat into energy.


Other Daytime Formula Ingredients Include:

  • Phenylalanine – Phenylalanine is an essential amino acid that can help decrease your appetite and prevent overeating.
  • Iodine – Iodine has been shown to help stimulate the secretion of thyroid hormones, which leads to an increase in metabolic function. (4)
  • Manganese – Manganese enables the body to more efficiently metabolize fats and carbs, and can also help to decrease cravings for junk food. It’s also an excellent nutrient for increasing calcium absorption.
  • Zinc citrate – Zinc citrate is able to stimulate thyroid function, and together with vitamin B6, zinc can also help increase the production of pancreatic enzymes, which are used to break down food.

The Night supplement ingredients include:

Fresh and dried green tea leaves on white background.

Green Tea Extract

Green tea is a potent antioxidant that has been used for thousands of years to promote good health, and has been shown to enhance weight loss by boosting the production of fat burning hormones. (5)

Griffonia plant on white background.Griffonia Extract 

Griffonia is an African plant whose seeds are used to create 5-HTP, a substance that enhances mood and produces a calming sensation believed to improve sleep quality. Because poor sleeping habits and fatigue can give rise to food cravings, getting a good night’s sleep is vital for any weight loss program to be effective.

Hops plant on white background.

Hops Extract

Besides being an important ingredient in brewing beer, hops also turns out to be an excellent sleep aid which can help you to fall asleep faster and more soundly. Not only that, it’s studies show that consuming hops reduces fat, especially in the abdominal area. (6)

Chemical composition of glucomannan on white background.


Glucomannan is amazingly effective at suppressing your appetite. This plant fiber expands in the stomach, helping you to feel fuller for longer, leading to a decrease in cravings and the desire to overeat. Studies show that it helps reduce both fat and body weight. (7)


Other Nighttime Formula Ingredients Include:

  • Chromium picolinate – Chromium picolinate is often found in bodybuilding and fat burning supplements. It helps move glucose out of the bloodstream and into your cells, where it can be more efficiently utilized. Research indicates that chromium supplementation can cause a significant decrease in body weight. (8)
  • Biotin – Most people associate biotin with growing healthy hair and nails, but it can also assist certain enzymes that are responsible for breaking down fat and carbs in the body.
  • Choline bitartrate – Choline attacks your weight loss and health from several angles, not only controlling fat storage, energy levels, and cholesterol, but maintaining the health of your liver, kidneys, and gallbladder as well.
  • Molybdenum (sodium molybdate) –Molybdenum helps with the body’s cell production, producing cells more quickly and efficiently, by using broken-down macronutrients to create energy. This type of energy is great for boosting your day and workouts, but also aids with digestion, regulates your heartbeat, and promotes the healthy function of muscles.
  • Pantothenic Acid (Vitamin B5) – Another one you probably thought was just good for your hair. Pantothenic acid also aids the liver with removing toxins and helps your body convert food into energy.
  • Thiamine (Vitamin B1) – Vitamin B1 is another nutrient that aids with metabolizing food; in fact, all B vitamins work in a similar way.
  • Pyridoxine HCl (Vitamin B6) – Considered by many to be the king of the B vitamins, Pyridoxine HCl is linked to over 100 enzyme processes within the body, and plays an especially vital part when it comes to the metabolic function of the body.
  • Ascorbic Acid (Vitamin C) – Besides being an excellent booster of the immune system, Vitamin C is works to increase metabolic rate as well. Its also able to help with your body’s recovery after workout.

Directions for use: Take one day pill every morning with breakfast. Take two night pills every evening  with a full glass of water before dinner. It’s recommended that these supplements be combined with a healthy diet and exercise routine for best results, both for weight loss and improved overall health.

The main takeaway here is that with its all-natural metabolism-increasing and weight loss-inducing ingredients, Phen24 is formulated to work every minute of every day non-stop, allowing your body to take full advantage of its fat burning benefits in order to experience the quickest results possible.

Potential Side Effects

Although the Phen24 website does not specifically indicate any side effects associated with use of the product, there is a caution against its use by women who are pregnant or nursing, and those under the age of 18. Additionally, people with diabetes, endocrine or autoimmune disorders, cancer, enlarged prostate, liver or kidney conditions, and those using anti-depressants are advised not take Phen24.

While doing research for this Phen25 review, I found that some users reported some side effects associated with the nighttime formula. These range from dizziness and headaches to diarrhea. There is always the possibility when taking any supplement that you could have an allergy with one or more of the ingredients. Talking with your physician prior to taking any new supplement is always a good idea.

User Reviews

While researching for this Phen24 review I came across a decent amount of customer feedback and testimonials. In general, users rate Phen24 as an effective product, with many reporting significant results for the weight loss product. Keeping in mind that this supplement is designed to enhance your current diet and exercise efforts, as well as improve sleep quality, the general consensus is that Phen24 is indeed highly effective at boosting the metabolism, burning fat, and helping you to quickly get trim and lose weight.

However, I did come across some negative reviews as well, from people questioning the effectiveness of the supplement. Unfortunately, they didn’t provide much detail regarding their opinions, although some indicated that the research studies were not convincing enough. For those who are interested in learning more about the clinical research supporting the ingredients used in Phen24, you can visit their main website for a list of the current scientific literature.

Where to Buy Phen24

The only reliable way to purchase Phen24 is through their official website. Please exercise extreme caution when buying Phen24 from places like Amazon or eBay, if not avoiding it altogether. Unfortunately, there is a huge problem with the internet being flooded with foreign-produced counterfeit knockoffs, which cannot be trusted to be safe or effective – it is simply not worth the risk.

As far as the price goes, taking into account that you’re two supplements in one package, the cost of a high-quality product like Phen24 is quite reasonable. One package containing both the day and night formulas goes for $74.99. Luckily, though, the more you buy, the more you save. If you purchase two packages you’ll get on FREE, and if you opt for three boxes, you’ll get two boxes FREE plus a FREE bottle of Advana Cleanse, a natural detox supplement that can help you lose even more weight.

Additionally, they offer free worldwide shipping and you are 100% protected by a 67-day money-back guarantee. If you’re not happy with the results you get, just send the unused portion back for a full refund, you’ll only pay for the return shipping.

Final Verdict: Pros and Cons


  • Using Phen24 can deliver visible, long-term weight loss that’s easier to maintain than any fad diet ever would be.
  • Targets weight loss in two different ways, with separate supplements for day and night.
  • Although certainly not cheap, for the results you get the pills are reasonably priced.
  • It’s formulated with all-natural ingredients that are proven to be effective. No artificial fillers or additives.
  • These pills work to enhance exercise and diet plans to make them more effective and work more quickly.
  • FREE shipping worldwide.
  • 67-day money-back guarantee. If it doesn’t work, your money gets refunded.

One of key highlights I found from using Phen24 is that not only does it do a great job to suppress your appetite, it also decreases your cravings for unhealthy junk foods. As many of you know, without those incessant cravings, it is far easier to stick to a healthier diet.

On top of that, the benefits of getting some solid, high-quality sleep simply cannot be overstated, and many of you may not even realize that it’s a problem. But you’ll definitely notice once your overall physical, mental, and emotional health all dramatically improve as a result!


  • Without a doubt, this product offers some great benefits – but even so, nothing is perfect. The best results (as we all know) are achieved by combining Phen24 with an exercise and diet plan. Remember – no product, including this one, is a magic wand for weight loss.
  • Phen24 is also not recommended for any person under the age of 18, so it should not be used by teenagers or children who are obese. It is also not intended for women who are pregnant or nursing. If this is you, you’ll need to find an alternative for the time being.
  • If you are overweight due to an underlying medical condition, Phen24 will probably not be effective in helping you lose weight. You should talk with your doctor to determine how best to initiate a weight loss plan.
  • Finally, because the formulas are proprietary, the manufacturer’s website does not offer exact quantities of the natural ingredients used in their product. In my experience, most people don’t mind as long as it works, but for a nutrition junkie and supplement reviewer like me, it’s a minor irritation.

Remember: no two people are alike, and everyone’s body is different, as well as our motivations for losing weight. Phen24 is an amazing tool, but it can only do so much for a person who’s committed to unhealthy lifestyle choices.
