You may remember our PhenQ review. When I found out the same company also makes Phen24, I was curious about how it worked.

Phen24 claims to support the body’s weight loss process 24/7 with its unique day and night pill formulas.

Our fitness experts dug deep to see if it was a legitimate weight loss supplement. We spent a lot of time researching their ingredients and looking at reviews.

Let's now go through our Phen24 review.

What is Phen24?

Phen24 is a two-part weight loss supplement, where you get separate Phen24 pills that you take during the day and a different set of pills taken as a night fat burner.

The day pill and night pill have different fat-burning ingredients that support your metabolism to help you lose weight 24 hours per day. We'll talk about the details as we go along this Phen24 review.

How Does Phen24 Work?

Phen24 works day and night to support your metabolism and increase your chances of losing weight.

Sounds simple as that’s basically how fat burners work.

I’m going to talk more about the natural ingredients later in this Phen24 review, but first, let’s discuss how Phen24 works in helping you lose weight faster.

During the day, you tend to move a lot whether you’re exercising or not. The activity causes your metabolic rate to increase and need more calories to keep up.

Your metabolism works differently throughout the day and night. It makes sense to take different pills to address the varied needs of your body.

If your body doesn’t get those calories through food, it will start using stored fat to fuel your energy levels.

The Phen24 day pills increase your metabolic rate and cause thermogenesis (a process that increases body heat) in response to weight gain.

It creates a fat-burning action that can help you burn fat and lose weight faster.

On the other hand, the night capsules has an entirely different effect on your body. Because your metabolic rate slows down while you’re sleeping, you don’t necessarily want it to mess up your body while you snooze.

The night pills focus on decreasing cortisol levels, promoting calmness, and reducing sugar cravings (late snacking is a difficult habit for a lot of us!).

What Are The Ingredients in Phen24?

The Phen24 ingredients are different in the day capsules and night pills, but I think it’s important to understand each ingredient in this dietary supplement to ensure if it will work for you.

I did some research and let's see how each ingredient work in this Phen24 review.

Phen24 Day Formula

Supplement Facts of Phen 24 for day time
  • Zinc: Phen24 says that zinc citrate is excellent for boosting the body's metabolism, but it can also support digestion and nerve function [1]. This essential mineral is vital to add to your diet when using Phen24.
  • Manganese: Manganese does a lot of work for the body, including energy production and regulating brain activity [2]. Your body naturally produces and stores a small amount of manganese, but a healthy diet will ensure that you get the full benefits.
  • Copper: Why on earth would you want to consume a heavy metal? Your body needs a tiny amount to aid with energy and collagen production and iron absorption [3].
  • Iodine: Iodine can help promote thyroid function. It doesn’t seem necessary in a supplement since most people get enough iodine in their diets [4].
  • Caffeine: A strong cup of coffee is one way to boost energy levels, but this Phen24 has caffeine to help get your day going. This ingredient is a natural fat burner, thus can improve physical performance and help you lose weight.
  • Guarana Extract: Guarana extract is derived from a Brazilian plant that contains caffeine. Commonly seen in energy drinks and other stimulants, guarana extract is a great supplement that can reduce fatigue, improve focus, prevent mood swings, and boost metabolic rate by 3-11% over 12 hours [5].
  • L-Phenylalanine: L-Phenylalanine is an essential amino acid, so you need to ensure that you are getting enough in your diet. L-Phenylalanine acts as an appetite suppressant in Phen24, but I didn’t find any studies that strongly support this notion.
  • Cayenne Powder: Commonly used in fat burners, cayenne powder can help increase body heat and act as a natural fat burner for your weight loss journey.

Phen24 Night Formula

Supplement Facts of Phen24 for night time
  • Ascorbic Acid: The main reason why the night capsules included vitamin C was that it supports and repairs muscles, but I couldn’t find any studies to support this. Vitamin C may also boost the immune system and manage blood circulation and blood pressure.
  • Calcium D-Pantothenate: This ingredient is part of Vitamin B5 [6] and Phen24 claims it helps with memory and increases stamina, although I couldn’t find much research to support those claims about pantothenic acid.
  • Pyridoxine HCL: It’s also known as Vitamin B6. Phen24 says it converts food into fuel to prevent it from being stored as fat. Vitamin B6 also supports protein metabolism and is vital for the nervous system [7].
  • Chromium: Chromium picolinate is often in fat loss pills. It doesn’t do much to help you in losing weight, but research shows that it acts as an appetite suppressant [8].
  • Thiamine HCL: Thiamine is more well-known as Vitamin B1. It has a vital role in metabolism as it helps turn food into energy [9].
  • D-Biotin: There are eight different versions of biotin, but D-biotin has full vitamin power. It supports metabolizing fats, protein, and carbohydrates.
  • Molybdenum: Molybdenum is an essential mineral. Since you only need small amounts of it, your diet should get enough of it. It does have significant benefits, like removing dangerous toxins from your body [10].
  • Glucomannan: Studies support that glucomannan can make you feel fuller, thus working as an appetite suppressant. It can help you lose weight, especially when paired with a calorie-deficit diet [11].
  • Green Tea Extract: Green tea extract has many research studies to back up its health benefits. When it comes to metabolism, green tea extract has been clinically proven to boost the metabolism and burn fat [12].
  • Hops Extract: If you suffer from sleep deprivation, then hops extract may help. Early studies suggest that hops extract can help improve sleep cycle and quality [13].

Phen24 Benefits

The recommended way to burn more calories and avoid weight gain is to exercise more, eat a healthy and balanced diet, consume more dietary fiber, and get plenty of rest.

Products like Phen24 act as a booster to help you achieve your weight loss goals.

As I review Phen24 or any other dietary supplement, I want to reiterate that it is not a magical solution that doesn’t require any work on your end even if it's considered as one of the best weight loss products in the market today. You still have to avoid junk food and get off the couch to see the best results.

Here’s a list of some of our recommended fat burners for men.

On that note, there are many ways Phen24 can help you lose weight faster, but in this Phen24 review, I narrowed it down to these 3:

1. Adjusts To Your Level Of Metabolic Activity

Your metabolism is more active during the day. While you’re sleeping, your body goes into Resting Metabolic Rate (RMR). It slows down and starts working on other body functions like digestion and blood circulation.

Phen24 adjusts to that, while most diet supplements don't.

The day pill has more active ingredients (i.e. cayenne powder) while the night pill focuses on calming down your body while still working on the metabolism, making your body burn more calories consistently throughout the day.

2. Aids In Weight Loss

Phen24 works every hour to help you lose weight.

It’s always working to boost and support your metabolism regardless if you are in the middle of a work-out or a deep sleep.

The ingredients in the both pills are there to give that extra effort to support both weight and fat loss.

3. Promotes Healthy Sleep

People often overlook sleep as a way to lose weight fast.

The truth is that you need to rest so your body can repair and restore your body, thus sleep and rest is just as important as your diet and active lifestyle.

The night fat loss pill has ingredients to promote healthy sleep through stimulating calmness, which can help you fall asleep while giving you the best results.

Metabolisms can be tricky. Sometimes when you do all the right things, you still don’t feel positive slimming results. That’s why we formulated a new system that heightens the thermogenesis process according to your sleep and wake cycle so that you can wake up feeling slimmer with more noticeable energy.

Side Effects


I couldn’t find a lot of reports of negative side effects.

Based on my research on the ingredients, it would be hard to get any side effects since it’s an all-natural supplement.

I could only see getting side effects from the caffeine. If you’re sensitive to it or consume caffeine from other sources, it may lead to jitters or some form of crash.

The company offers a 60-day money-back guarantee, so if you experience any adverse effects while using Phen24, you can contact them to get a refund.

Phen24 Reviews

Based on the reviews I read, people who use Phen24 achieved positive results when combined with a healthy diet and exercise routine. They were able to lose weight and burn fat and some even consider it as the best supplement they've used to lose excess weight.

Here are some Phen24 reviews I found:

Is Phen24 FDA Approved?

The FDA has not approved Phen24. Dietary supplements, unlike prescription medications, don’t need approval from the FDA for safety and effectiveness.

I always highly recommended investigating each ingredient to see if it has beneficial ingredients.

Who Should Not Take Phen24?

People should not take Phen24 if they are:

  • Pregnant or nursing
  • Under the age of eighteen
  • Taking anti-depressants
  • Diabetic
  • Diagnosed with autoimmune disorders, cancer, liver disease, or kidney disease

Phen24 is suitable for most people, but you should consult with a health professional if it is a good option for you.

How Long Will One Box Last?

One box lasts for 30 days. It has 30 of the Phen24 day pills and 60 of the Phen24 night pills. You take one day pill with your breakfast, and two night pills fifteen minutes before your evening meal.

How Long Does It Take To Start Seeing Results?

Every person is different, so it will vary on how long it takes to see results. It can take time for your body to readjust to a new fat loss pill.

Most people should see results within two months of taking Phen24 pills, but you could see a difference within the first month.

Where Can You Buy Phen24?

You can buy Phen24 directly from their official website. It’s not possible to buy it anywhere else, but that’s a good thing. It ensures that you receive the genuine product and not a knock-off.

Is There A Money-Back Guarantee?

There is a 60-day money-back guarantee from the brand's official website. You have to return any unused product (even empty bottles) to them, and then they will issue a full refund minus the cost of shipping.

Is Phen24 Vegan/Vegetarian?

Yes, both the day and night pill are 100% vegan and vegetarian. It is considered as one of the best and most effective weight loss pills in the vegan community. If you have any dietary restrictions as a vegan or vegetarian, you may take Phen24 as it won't mess up your diet.

Should You Buy Phen24?

phenq before and after

Based on our Phen24 review, the day and night fat loss pills seem to be an effective metabolism booster. The natural ingredients are backed up by science to help you with weight loss all day every day.

However, having to take separate pills for day and night may be an extra strain in an already busy day and a possible cause of confusion. And there's a way to achieve the same, even better results with just one bottle instead of two separate ones.

If you’re looking to keep things simple and achieve the significant weight loss benefits, we’d suggest sticking to the old proven way of adding PhenQ to your diet and exercise plan.

It will give you an extra push in the right direction, especially if you are working hard in the gym and are mindful of your food intake. You can purchase it directly on their website here.
