Struggling with weight problems is already stressful enough on its own, so choosing the right fat burner should be a breeze, but it often turns into just another nightmare.

Deciding what products are legit and which ones are a scam is a challenge, so we decided to review probably one of the most debated weight loss products on the market.

Phen375 has been around for some time, and you probably heard some rumors about it. That's why we will focus on facts in this Phen375 review to help you decide whether this is the right supplement for you.

What Is Phen375?


Phen375 is a dietary supplement designed to help those struggling with excess weight. Its potent formulation burns fat faster by speeding up metabolism, boosting energy, and suppressing appetite.

According to the manufacturer and some satisfied customers' positive reviews, Phen375 is one of the most efficient weight loss supplements and fat burners in pill form on the market.

Thanks to the stimulating effect, you'll be able to exercise longer, which can help you build muscle mass and burn more fat.

It's designed specifically for those who want to get rid of excess fat quickly and "effortlessly" but, is this even possible?

Despite some warnings and not-so-great reviews, people are still drawn to this product that promises a great way to lose weight  in a short time, and thanks to the "money back guarantee" policy of the company, folks are willing to give it a chance.

But, how does Phen375 work, and is it safe? Let's take a close look at the ingredients and see what a single pill contains and what you get from it.

Ingredients List

pure ingredients

Don't skip reading the fine print on your dietary supplements, especially diet pills. Many weight loss supplements out there have been known for containing some dodgy ingredients, so make sure to check what you get.

1. Caffeine Powder

Like many other fat burners, Phen375 also relies on caffeine for its proven efficiency in fat loss.

This powerful stimulant is known to be highly effective in appetite suppression and athletic performance enhancement. In conjunction with other ingredients, caffeine powder speeds up metabolic rate, which helps lose weight and burn fat faster.

This ingredient also boosts endurance and stimulates the central nervous system making you more energized and alert.

2. L-Carnitine

Being one of the essential amino acids, L-carnitine helps your body convert fat into energy by stimulating protein production.

Some research supports the claim that L-carnitine effectively promotes weight loss, but others claim that it doesn't have a significant impact on weight loss in healthy individuals.

3. Coleus Forskohlii Root

This plant has been used in Ayurvedic medicine for conditions such as asthma, and over the past few years, it has become a popular ingredient in weight loss supplements.

Although some studies have confirmed its fat-burning effects, there's still no definite conclusion on its effectiveness in weight loss [1].

Active ingredients in forskohlii stimulate the production of cells that may promote fat burning. As a plus, no serious side effects have been linked to this natural ingredient.

4. Cayenne Pepper

It's okay to be a little skeptical about the effectiveness of the ingredients such as cayenne pepper in weight loss supplements, but according to the International Journal of Obesity, an active ingredient of cayenne pepper, called capsaicin, is somewhat effective in appetite suppression.

Capsaicin increases your body temperature and boosts metabolism, making it burn calories faster [2].

It also plays a role in sleep regulation, which makes it great for achieving energy balance.

5. Citrus Aurantium

Also known as bitter orange, citrus Aurantium is used in many fat burners for metabolism regulation and fat mobilization.

However, citrus Aurantium extract also contains an ingredient similar to the main component of the plant called ephedra, which acts as an energy booster but has also been linked to heart problems and blood pressure increase. [3]

You'd think that all-natural ingredients are safe, but that's not always the case.

6. Calcium Carbonate

This affordable ingredient has been associated with improved metabolic rate, which is why it's commonly found in various weight loss supplements [4].

Calcium stored in fat cells plays an essential role in how fat is stored and processed in the body, so there is good evidence to back up the claim that a high calcium diet can promote weight loss.

Another reason for throwing calcium in the mix is to help you digest the other ingredients of Phen375.

7. Dendrobium Nobile Extract

This orchid-like plant originates from Asia and has a long history of use in traditional Chinese medicine. It has recently been found in many pre workout supplements as a stimulant that regulates energy levels and boosts athletic performance.

The use of Dendrobium nobile extract in workout and weight loss supplements has been on the rise lately despite the lack of comprehensive studies that confirm its effectiveness.

Pros and Cons

Some of the ingredients in Phen375 can:

  • speed up your metabolic rate,
  • keeping your energy levels high throughout the day,
  • removing excess fat (and even helping you gain muscle mass)

but let's see what its downsides are.

Are There Any Side Effects?


Adding any dietary supplements, especially weight loss pills, should be taken with a dose of caution, especially if you are sensitive to some of the ingredients.

Although it's rare, some people reported mild side effects when using Phen375, such as:

  • insomnia
  • jitters
  • headache
  • heart rate and blood pressure increase
  • upset stomach
  • nausea, and dizziness

So maybe it's best to consult your doctor before making any major changes to your regular dietary supplements and your diet plan.

Also, allergy-prone folks should carefully check the ingredients list.

But when you think about it, every time we buy some over-the-counter medicines, we don't even bother to read ingredient lists and warnings because we are not planning to overuse them. Side effects must be listed even on some food types, but that doesn't make them unsafe, especially when consumed in moderation.

  • Effective fat burner and appetite suppressant
  • Boosts energy levels and promotes endurance
  • Comes with a diet and exercise plan
  • A bit expensive
  • Some side effects were reported
  • Complicated refund policy

Where to Buy Phen375


The only way to avoid wasting your money is to purchase Phen375 from the official website or by clicking on affiliate links.

According to the manufacturer, there's no wholesale program for Phen375, so you won't be able to buy it at your local store, like Walmart, Amazon, eBay, and similar websites.

Watch out for fake products with the same or similar names offered on some websites and online stores.

In case you change your mind after purchasing this product, there's a 60-day money-back guarantee, but keep reading to find out exactly how that works.

How to Take Phen375?

One bottle of Phen375 contains 30 pills, which will have you covered for one month. Taking a single pill in the morning with plenty of water should help control your appetite and curb food cravings, making it easier for you to keep up with your healthy meal plan.

Fat in our body acts as storage for toxins, so when the fat burning process begins, you can expect toxins to be released. That's why it's essential to drink a lot of water (2-3 liters per day) while taking these pills.

But it's not as simple as it sounds. The manufacturer recommends exercise and reducing your calorie intake to around 500 calories per day to see results.

If you don't notice any change within 30 days, you can rely on their 60-day money-back guarantee policy. But there's a catch.

You'll be eligible for a refund only if you follow their instructions to the T, which means downloading their recommended diet and exercise plan, taking Phen375 and keeping a weight loss diary, and recording your final weight after 30 days.

It seems like too much work, so probably this is where some potential customers get turned off and decide to go for easier solutions.

Phen375 Reviews from Users

It's hard to deny the benefits of Phen375 when you look at the photos of satisfied users and hear their success stories, but if that were so compelling, you wouldn't be reading this review, right?

Each user is different and has a unique story, so it's natural to get mixed reviews from time to time. Some people swear by it, others have mixed feelings and so-so results, while others didn't have anything nice to say about this supplement.

One customer claims: "I started at 130 lbs, which is pretty heavy for my frame. I thought it would take forever to get to my goal of 105lbs, but I did it in just 40 days. I feel great and I look much better now."


Is Phen375 FDA-Approved?

The FDA is not the right agency when it comes to dietary supplements approval since they only approve medicines. Phen375, like other supplements, is not FDA-approved. However, it holds a good manufacturing practice certificate. It is produced in the FDA certified facilities, which means that they can check the ingredients and production process to determine if the product is made in accordance with standards [5].

Is Phen375 Safe?

Despite some mild side effects, no serious cases have been reported yet.

It's okay to be worried about possible unwanted effects because no weight loss pill is completely risk-free.

You probably heard that controversial chemicals and illegal substances have been found in some dietary supplements in the past, but fortunately, that's not the case with Phen375. It's a safe non-GMO product free from harmful substances.

As we mentioned above, when a healthy person takes Phen375 in moderation and according to instructions, only minor side effects may occur.

Does Phen375 Contain Phentermine?

The short answer is - no, it doesn't. Phen375 was developed as a safe alternative to Phentermine, which used to be considered one of the most effective weight-loss ingredients on the market. Nowadays, slimming drugs that contain Phentermine require a prescription, while Phen375 doesn't. It's an herbal alternative to prescription diet products that contain Phentermine.

Who Can Take and Who Should Avoid Using Phen375?

It seems that Phen375 works equally well for both men and women. Anyone who doesn't have a pre-existing serious medical condition can safely enjoy the benefits of Phen375.

Since it's non-GMO and doesn't contain any animal products, this supplement is also a good choice for vegans and vegetarians.

To achieve the best results, you should follow a low-calorie diet and exercise regularly, so you should not start the Phen375 weight loss program if you have health problems that make dieting and exercise risky or dangerous.

If you have a health condition and take medication that would interact with Phen375's ingredients, it's best to talk to your doctor first.

Also, anyone under the age of 18, pregnant, or breastfeeding women should not take this product.

Do You Need to Diet With Phen375?

Keep in mind that any weight loss supplement has minimal effect on its own, so diet adjustment is necessary for best weight loss results. Phen375 has you covered as it conveniently comes with a diet plan and exercise videos that you can download from their official website.

Phen375 is not a magic weight loss pill, but with a proper low-calorie diet and workout routine, it can help your body to burn fat faster and lose weight as a result.

Phen375 advert reads, "Let Phen375 assist you in your weight loss journey" - and, according to several testimonials, that's precisely what it does.

Does Phen375 Really Work?

As you would assume, achieving visible weight loss results requires much more than just swallowing a pill - a strict diet, workout, and abundance of dedication and motivation.

Judging by numerous positive reviews and testimonials on the company's official website, this seems to be a reliable and effective fat burner, when taken properly, that can assist you in reaching your weight goals as a part of your healthy diet and active lifestyle.

But your overall health condition, diet and nutrition, and physical activity are what, more than anything determines if this Phen375 pill will be effective for you or not.

Should You Buy Phen375?

"On average Phen375 users could expect to lose 5 to 10 pounds per month along with a low calorie diet and low to moderate exercise.", the manufacturer claims. But will Phen375 work for you as well?

Although Phen375 seems to come with many benefits, such as appetite suppression, higher energy levels, and fat burning effects, you shouldn't be disappointed with this product as long as you don't have unrealistic expectations.

The question is, are you ready to change your habits and lifestyle and follow the steps of the Phen375 diet and exercise program? I guess that this is the point where most folks lose motivation rather than losing weight.

Taking diet pills alone is easy, but getting the results you want is a whole different ball game. So, if you're ready to take the plunge, this product might be worth trying.
