Customer Reviews, Ingredients, Side Effects, Prices and Where To Buy It

Phen375 Overview

Phen375 is a flagship product of the world-renowned supplement company called RDK Global. It is a pharmaceutical grade weight loss supplement derived from the weight loss promoting drug called phentermine.

This supplement mimics the power of the phentermine drug whose main benefit is to suppress or reduce your appetite. Nonetheless, Phen375 is much more than an appetite reducer.

It is a complex of natural active ingredients that have a synergistic action and allow weight loss without rebound effect.


Why should you choose

In this review of the supplement Phen375. Here we explain what the Phen375, how it works, what ingredients contains, their side effects, reviews of real customers, prices, and the best places to buy it (last update 2018).

Getting The Most From Phen375

Phen375 offers a few ways to target weight loss, It suppresses your hunger and burns your fat levels. By speeding up your metabolism and enhancing your energy levels, Phen375 keeps you active throughout your daily tasks.

  1. Suppresses your appetite
  2. Improves fat burning
  3. Better energy throughout the day!

Through suppressing your hunger, which is what Phen375 was originally designed to do. You eat less and in turn burn more calories than you consume over time. This process has been proven time and time again to be the best way a user can lose weight in the long term.

How Does Phen375 Work?

Phen375 acts by stimulating metabolism, reducing appetite, promoting the oxidation of stored fats and, most of all, helping decrease the body’s ability to store fat.

1. Stimulates the oxidation of fats at the cellular level

Thanks to its components, Phen375 facilitates the entry of fatty acids into cells so that they can be used and converted into energy. In this way, fats stored in excess may oxidize and body weight may decrease. This applies primarily to those who have difficulty reducing fat in problem areas such as hips, waist, and thighs.

2. Facilitates the maintenance of muscle mass or lean mass

This is a fundamental effect since most people who start a treatment for weight loss, lose weight not only at the expense of fat but, above all, by the loss of muscle mass. This is counterproductive since the muscle is more active and spends more calories to maintain itself. Within the total caloric expenditure of a person, muscle mass contributes a large part. This is why many fat burners do not work in the long term.

3. Rise the levels of energy

Thanks to its components, Phen375 boosts AMP cell levels. This is a substance that is directly related to the levels of energy and vitality. This is a very important effect considering that many people start diets low in calories, with a low density of nutrients which leads them to feel fatigued and apathetic much of the day. This is not only the effect of the lack of essential nutrients but also as a consequence of hormonal and humoral changes.

4. Increases thermogenesis

This means that it increases the heat it expels through the burning of the ingested nutrients. This can represent up to more than 200 extra calories burned per day. Thermogenesis induced by food is a factor that can be altered among other causes by the temperature of food, as well as by certain substances such as capsaicin and caffeine.

5. Reduce hunger signals

Thanks to its anhydrous caffeine powder content, Phen375 enhances the sensation of satiety and boosts fat burning. It is known that caffeine acts by stimulating fat metabolism and anhydrous caffeine powder possesses these benefits without the commonly associated adverse effects.


According to a research at Columbia University, a person would have to walk 40 hours weekly to lose the same amount of weight as taking 7 dosages of Phen375:

  • The researchers found it is 100 % safe.
  • Produced, manufactured, and distributed in the United States
  • Many diet tablets are made in unhygienic laboratories by unlicensed chemists in India, China, and other 3rd world countries, Phen is made in the US so it undergoes United States law.
  • FDA Certified Laboratory
  • Unlike other diet pills, Phen 375 is made in an environment accepted by the Food and Medicine Administration (FDA).

Each Serving of Phen375 (1 Capsule) Contains:​

It is important to consider the chemical composition of the supplements for weight loss. It is not only the ingredients but the amount to which they are added.

This amino acid helps with the function of the brain and heart, helps with muscle movement and is important for the production of energy.

Caffeine powder anhydrous (Capsicum Frutescens)

This version does not contain water, unlike the caffeine stimulant that is commonly used in supplements. This version is typically more powerful and can help increase mental focus and raise energy levels. Caffeine has also been shown in some studies to suppress appetite and increase metabolism.

Cayenne (Capsicum) 10M HU / G

Also called capsicum annuum, this spicy fruit is used in all kinds of food dishes, as well as over the counter diet products. It contains a compound called capsaicin, which can help reduce inflammation, promote satiety and promote weight loss.

Citrus Aurantium Extract (Standardized to Synephrine 10%)

Also called bitter orange, it is a citrus plant native to Southeast Asia. It contains a chemical called synephrine, which has been shown to increase heart rate and raise blood pressure.

How To Take Phen375

You only need to take one tablet of Phen375 per day, together with water. This is a formula of 800 milligrams, so it is supposed to be powerful. Keep in mind that you are told to eat a variety of healthy foods (well-balanced diet) while you are taking this diet product.

In addition, it is advisable to reduce your daily caloric intake by 500 calories to help improve the results of weight loss. Finally, it is considered taking the Phen375 tablets for at least 30 days to see solid results.

Reducing your daily caloric intake by 500 calories per day will help you lose weight, especially if you have not had dietary treatment before, if you are a sedentary person or if your intake of sugar and/or fat is usually high. This deficit of calories will cause your body to use stored fat as an energy source, which leads to weight reduction.

If you are under 18, or you are pregnant or breastfeeding a child, you should not use Phen375. Also, if you have a pre-existing health problem and take a prescription medication, you should talk to a doctor before taking this weight loss formula. After all, it could cause health problems or interact with the medication you are taking.

Are There Side Effects?

There are some side effects of Phen375 that should be considered. According to the reviews, some users have experienced the following reactions:

  • Headache
  • Stomachache
  • Dizziness
  • Changes in stools
  • Accelerated heartbeat (tachycardia)
  • Anxiety
  • Nervousness
  • Nausea
  • Elevation of blood pressure
  • Abdominal cramps

We also consider the ingredients of Phen375 tablets.

After all, certain substances have been linked to adverse reactions. Like other weight loss products that are sold online, Phen375 contains a combination of Citrus Aurantium (bitter orange) and caffeine (a stimulant).

When taken together, these ingredients can cause side effects and health problems, mainly related to the cardiovascular system and nervous system.

You should talk to your doctor before taking a product that contains this combination of ingredients, just to be sure.

Is It A Scam?

Phen375 is considered a scam by some people. However, its ingredients have proven efficacy, especially in people with a history of chronic diet.

The extreme reduction of calories in a constant way generates a metabolic adaptation that leads the person to stagnate in the weight.

On the other hand, the metabolism is damaged with a very low basal metabolic rate. The Phen375 supplement contributes to recover your metabolism thanks to the effects mentioned above.

There are many stories of individuals buying Phen375 supplement from Amazon and receiving fake tablets instead of the genuine ones!

You will not be getting money back assurance, you will not be getting the normal consumer support and as I currently mentioned you risk of not getting an original product.

I tried and failed with many other products. I lost 93 pounds with Phen375. My starting weight was 293 pounds, and my goal was to reach 200 pounds. I reached my goal in 6 months, and I couldn't keep my desired weight through a lifestyle and exercise healthier. Thanks, Phen375!
I am very shocked by the criticism of this product. I have used it for 2 days, and I see a complete difference in my appetite. Without nerves. I've been drinking more water and helped me. As small meals, 4 to 6 times a day and I can say that I have no hunger as I normally have. Will review it again next week.
Yes, these pills work, there is nothing hidden and no invention. It suppresses my appetite and causes me not to eat running rampant during the day. I am making a smoothie diet and increasing my consumption of water. I loved this product, and so, definitely, I recommended them to my friends. I've been taking it about 2.5 weeks.
When my friend suggested Phen375, I was a little hesitant. It simply sounded to great to be real and I ‘d never ordered diet tablets off the internet. She insisted I obtain a week’s supply and let me tell you. It works !!! I’ve been taking Phen for 6 weeks now and have actually lost over 25 pounds!

Overall Review:

Phen375 is a supplement that permits the loss of fat in the context of a treatment for reducing body weight. It does not always produce the same effects since obesity and overweight are entities of very complex origin and treatment.

However, it is one of the few supplements on the market that addresses the different difficulties for which weight loss does not occur. It helps by changing the metabolism, acting on lean mass and reducing appetite, that is, it is a complex with multiple benefits.
