And every week you see the addition of dozens of new products, all claiming to help you lose weight, speed your metabolism, and help your overall health.

Phen375 is one such product gaining popularity lately, but does it actually shrink your waist…or just your wallet? Let’s take a closer look…

Brand Overview

Appetite suppressing pills

It took a bit of searching, but we found that Phen375 is manufactured and distributed by RDK Global, based out of Texas. They have been in business since 2006 manufacturing various weight loss and pain relief supplements.

It appears as though most (if not all) of their products are FDA-approved, created in labs across the US and Europe, though they primarily operate out of their Dallas, Texas facility.

RDK Global is a small company, with roughly only 50 employees providing customer service and support, and Phen375 is the main weight loss product that RDK Global promotes and sells.

Products and Claims

According to the Phen375 website, Phen375 will produce the following results:

  • Fast, easy weight loss! Maximum-strength ingredients to help you get the body you want
  • Lose up to 20 lbs per month! (Lose 2-5 lbs per week) At less than $3.80/day, a slimmer you is just around the corner!
  • Boost your energy & metabolism! Feel faster, quicker, and stronger

Phen375 apparently is mostly an appetite suppressant, as described on the Phen375 website:

Phentemine 375 has been designed to help suppress appetite as well as increase the body’s metabolic rate. The most common reason that dieting is not successful is the inability to control the appetite and maintaining a slow metabolic rate.

Appetite control is essential to long term weight loss. Meals should never be skipped- rather, they should be controlled. Skipping meals actually forces your body to go into a starvation mode. It slows down the metabolic rate to preserve itself and makes the fat burning process harder. Ideally, you want to reduce calories, while also increasing meals. Phen375 significantly aids you in controlling your appetite, which makes the process easier to accomplish.

Rapid weight loss is accomplished or occurs when your body requires calories that are not present in the body. The body has to first break down fat into practical energy. However, fat is where the body stores toxin. Once the fat burning process begins, it also releases toxins.

The best way to flush these toxins is to consume a healthy amount of water – Phen375 is designed to naturally help increase water intake, to ensure that these toxins are flushed from the body.



These are the ingredients and claims, according to the Phen375 website:

  • Calcium Carbonate 36% GRAIN
  • Chromium(PIKOLINATE) 12%
  • L-Carnitine(L-TARTRATE) 68% – Mimics the Human Chorionic Gonadotropin (HCG) that transport fatty acids through to your metabolism. HCG aids in the release of stored body fat, into the bloodstream for energy; making your body burn existing fat easier. Because it is easier to burn fat, your body does not need to burn away muscle therefore eliminating the problem of muscle deterioration often suffered by dieters.
  • Citrus Aurantium(Fruit) extract {Standardized for 10% synephrine}
  • Caffeine Powder Anhydrous(Capsicum frutescens)
  • Cayenne(CAPSICUM) 10M HU/G
  • Dendrobium Nobile Extract (from orchids)
  • Coleus Forskolii Root PE(10% Forskolin)
  • Sympathomimetic Amine (Citrus Aurantium) – A natural stimulant that helps you constantly burn fat by increasing your metabolism. This is how we super charge your metabolism.
  • 1,3,7-Trimethylxanthine (Caffeine) – Helps to trick your brain in to believing you are full which means your body has to burn more fat to get the energy it needs. Also, by reducing hunger you eat less, allowing you to easily reduce your food intake.
  • Capsaicin-1.12 – Included at a powerful 12 to 1 concentration which helps ensure the other active ingredients are carried throughout your body by increasing blood flow in smaller or restricted flow vessels very common in fatty tissue. Capsaicin also increases your body’s temperature allowing you to burn up to 270 calories more per day than you normally would, this process is called thermogenic burn as the body increases temperature it requires more energy to burn thus eliminating fat effortlessly.

It should be noted here that we could not find an exact list of ingredients or an image of the Nutritional Information label on the website. It was not made clear if these were the only ingredients or just a portion of them.

Regimen Recommendations and Suggested Usage

A person deciding what to purchase online

We would love to show you the Regimen Recommendations and Suggested Usage according to the Phen375 website…except for the fact that there aren’t any to be found on the Phen375 website.

The site urges you (repeatedly) to order NOW, also giving you the incentive to receive a “free diet pill plan” and “cellulite reduction report” (no idea as to what that is, nor is there any explanation), but there is no mention on any page as to instructions for taking the Phen375 product.


The Phen375 website kindly provides an entire tab to “Testimonials and Success Stories,” which includes about a dozen client reviews (“testimonials”) including before/after photos with each. There is also a “Video Gallery” at the bottom of the page that includes 4 client testimonials. There is no area to simply enter a “Review” though, and therefore, there are no negative reviews listed.

Outside the Phen375 website, reviews were not as overwhelmingly positive. On sites that seemed paid to promote the product, reviews were glowing. Major selling points included increased energy and significantly reduced appetite…and, as a result, weight loss.

Some were gracious enough to include minor drawbacks, including mild dizziness, inconsistency in sleep patterns, slight loose stool every now and then, and higher blood pressure levels… though none of these were severe enough to discount the effectiveness of the product.

However, on open sites with everyday users posting reviews, most claimed the product simply did not work at all. There were no major complaints other than the fact that there was absolutely no weight loss shown.

Overall Rating

A stop sign in the field

There were several red flags that came about while researching Phen375. First of all, the “About Us” at bottom of the home page on the website just redirects you to the top of the main page again.

We tried several different computers, but it appears that it is linked on a loop. So, does this mean that there is no info about the company? Then why have an “About Us” link at all?

Another red flag…the name itself. None of the listed ingredients included anything “phen” related.

So that leads us to think that this company was obviously looking to capitalize on the documented weight loss results of the famed “fen-phen” diet pill that contained phentermine and fenfluramine, removed from the market several years ago (due to the fatal pulmonary hypertension and heart valve problems it was said to cause).

Phentermine was found to be the safer of the two, and decidedly effective on its own. So is this why RDK Global has so named the product?

And lastly, the lack of unbiased reviews included on the site, as well as the fact that there was no Nutritional Information as it appears on the bottle listed anywhere on the site, were both slightly troubling. It just took a little too much effort to find out the necessary info on Phen375…and that’s usually not a good sign.

Our rating: 1.5 (out of 5)

Be skeptical!
