Phen375 Reviews, Ingredients and Ratings: Worth Buying or Not?

Phen375 is a hugely popular weight management supplement all over the world, and our review will start by discussing the various differences in composition and marketing methods, considering the fact that in the US testimonials seem to be the foundation of this supplement’s promotion strategy. Obviously, the main part of the article will be dedicated to a documented analysis of the eight components of “Phen375”, because the customer actually pays for the pills, not for testimonials.

Tampering with the human metabolism in order to achieve the desired shape is an appealing proposition, even for individuals with an adequate weight. It can be perceived as one more manifestation of mankind’s dominion over nature, “human nature” this time. Maybe this is the reason why weight loss dietary supplements are so popular, aside from contemporary culture of attractiveness. Yet, the supplements’ very status (from both a medical and commercial point of view) are shrouded in uncertainty.

In this review, we will try to dispel some of the uncertainty surrounding “Phen375”, a supplement designed in the wake of the legal banishment of phentermine, a popular weight loss drug, which proved to have serious side effects but, considering that it was practically an amphetamine, surprise shouldn’t have occurred at its inclusion in the controlled substances category. Based on the conclusions we will draw as to the credibility of the company manufacturing the supplement, the legitimacy of the claimed effects, and relevant existing reviews from other historically objective reviewers, we will provide you with an unbiased advice on whether you should include “Phen375” in your weight loss action plan.

Phen375 – Official Presentations

The contextual history of this supplement actually begins way back in 1959, when phentermine, a drug prescribed for short-term use and short-term weight loss hit the market. Most people nowadays are familiar with the widely practiced abuse of prescription drugs characteristic of that era.

Phentermine has traits that make it similar to amphetamine. In the present day is a controlled substance, only to be used in cases of severe obesity for no more than 12 weeks at a time, due to its likely addictive nature. Although its side effects in the short run are negligible, they nonetheless exist and a prolonged use may lead to various afflictions of the heart, lungs, stomach, and the central nervous system. The drug was available over the counter for almost forty years, finally being banned in 1997 and, naturally, it had acquired a huge popularity over that time for its efficiency as an appetite suppressant and energy booster. Nevertheless, the aforementioned risks sound awful enough, with the interdiction being entirely justified.

In the wake of that change, dietary supplements’ manufacturers rose up to fill the void in the weight loss products segment. Since then, “phen”- seems to be on its way to becoming an established English language prefix, with Phen375 claiming similar slimming benefits since 2009. With the aid of high-quality ingredients and with no prescription needed. As trivia information, we should also mention that the usual prescribed dosage of phentermine is 37.5 mg.

Phen375 claims to deliver the speediest weight loss in the business, and its popularity and demand for in many regions of the world (though we will only discuss the US, Australia, and Europe) backs up that claim. It may well have been a stand-out product when it was first launched – due to it being both a fat burner and an appetite suppressant – yet in the landscape of 2017, it is merely one member of an extensive pack.

Phen375 Claims and Testimonials

The first thing that catches a reviewer’s eye when exploring the official website is the overuse of testimonials, one can simply not escape them, a practice whose best days are certainly behind us. Their presence hinders every page of the website, and there is a dedicated “testimonials” page to boot. This amounts to conspicuous overselling of the product. They could just have started with the 60-day money-back guarantee and assurances of domestic manufacturing in FDA-approved facilities, like most supplement manufacturers and marketers do. phen375-testimonials-884x1207 The second noteworthy feature in the case of Phen375 involves the supplement’s recipe – the American version features eight ingredients (calcium carbonate, chromium, L-carnitine, caffeine powder, capsicum, orchid extract, citrus extract, and Indian coleus root extract), while the European supplement can do without the last two. This aspect leaves a big question mark over role these two ingredients have in the overall mixture, in addition to why have they been left out, while declaring no change in the product’s effects. Furthermore, the role of the two contentious ingredients is never officially elaborated on, which sparks further unresolved curiosity on the part of the reviewer. Besides the active ingredients, Phen375 also comes with its own diet plan.

The purported weight loss sequence seems straightforward enough. It starts from the universally acknowledged truth that the established three-meals-a-day is still the way to go and one should never skip meals, but rather watch the meal’s content. The active ingredients in the supplement start the process of burning down the existing fat in the body. With a careful intake of water, the toxins which are unleashed from said fat will be flushed out gradually. The credibility of this plan is enhanced by the fact that it does not totally remove exercise from the weight loss equation, as other such supplements do. All the claims discussed so far have a decent degree of plausibility, but waters do become murky when turning our attention to what should be the manufacturing company.

Although the official website clearly advertises that the product is made in the USA, the “Contact Us” information lists only a Distribution Center located in Dallas, Texas. The terms of use, privacy and return policies do not shed more light on what or who actually makes and sells the supplement. The credibility is further dented when considering the affiliate program, which translates into a suffocating presence across the web, with the same testimonial-inspired promoting techniques.

phen375-reviews-testimonials-884x384 Leafing through dozens of testimonials and “objective reviews”, we have encountered what can only be deemed as the “best case scenario” one can realistically expect from a diet involving supplementation with Phen375. phen375-review-testimonials

Where to Buy Phen375?

phen375-bottle30 “scientifically researched”, “GMP certified” Phen375 tablets cost $65.95 (with an additional $15.95 for shipping), presumably a month’s stock, though nowhere on the official website is there an indication of how many pills per day one should take. Naturally, there are other deals – $131.90 for three packs or 90 tablets (plus the aforementioned $15.95) and $263.80 (plus $15.95) for 180 tablets.

From the testimonials in affiliate websites, we have concluded that the weight loss results of Phen375 become a palpable reality after at least 12 weeks of using the supplement, in conjunction with the respective diet plan.

The Australian official website dedicated to Phen375 takes a different approach where, in addition to the information we have presented thus far, it commends the product’s qualities in relation to some certified weight loss drugs and other supplements. Phentermine is known by the name of Metermine in Australia and, apparently, can still be bought over the counter. Obviously, Phen375 comes out in a positive light by comparison, as it does not have an addictive potential or the serious side effects of phentermine. There are several similar such instances with other prescription drugs or dietary supplements, through which the product comes out as the best possible option for people desperately seeking to lose weight.

Things become interesting when one tries to actually place an order of Phen375 through the website. A company called RDK Global has the rights to manufacture and distribute the supplement in Australia. Nevertheless, it is stated that the tablets are made in the United States, and are delivered from there to Australia and other parts of the world. Anyway, the connection to the US-based official website is never denied (although never implied) and several outbound links from the Australian point to the American version. The Australian website also contains a section dedicated to another weight loss dietary supplement – PhenQ. Though not much space is dedicated to its promotion, it is still odd for a competing product to be present on the official website of another.

PhenQ is a supplement promising about the same results as Phen375, however, it has different ingredients, in the US is sold by a company called Wolfson Berg Ltd. The phonetical likeness is pretty much where the connection ends, seemingly. The only logical explanation of this state of facts is that RDK Global is an Australian vendor that deals in many dietary supplements, an aspect that, for us, is a further dent in Phen375s overall trustworthiness. In this section, we have established the relationship between phentermine, a dangerous yet long-lived weight loss drug, and Phen375, a dietary supplement with many question signs hanging above its promotional techniques and manufacturing/parent company. So far it is not a supplement which deserves much praise or expectations. Let us see if its combination of ingredients can modify this rather poor first impression.

Sizing Up Phen375 Ingredients

In the official presentation, there are six featured ingredients, common to both the US and European versions of the product, from where we conclude that they are the most important. That being said, no dosages are mentioned with the exception that one tablet of Phen375 weighs 800 mg.


L-Carnitine is supposed to fulfill the important function of transforming the stored fat in the body into an active source of energy. One of two isomers of carnitine to be found in the metabolism of plants and animals, L-carnitine acts as a vehicle for transporting vital fatty acids in the mitochondria of eukaryotic organisms.[1]

Humans get their necessary intake of carnitine from meat, and a chronic deficiency may lead to numerous metabolic conditions, which can be successfully treated with supplementation. A dosage of around 200 mg per day is sufficient and can be easily assimilated from an omnivorous diet, although chronic carnitine deficiency is mostly attributed to genetic defects, rather than radical vegetarian diets.[2] A dosage between 1 and 2 grams per day has shown to help with certain cardiovascular conditions like peripheral artery disease, and also in cases of thyroid problems, although no definitive studies exist on the issue. L-carnitine supplementation has been a craze among athletes ever since it became available over-the-counter and some sports federations have imposed bans against it. With these arguments, a case can be made for the validity of the Phen375 claims, though it is a slim case because we lack conclusive information about the dosage.

Caffeine Powder is used in the supplement for preventing cravings and, although not specifically mentioned to provide the extra energy the organism loses because of the reduced nutritional input. Like carnitine, it is an ingredient common to most weight loss products.

From the scientific point of view, caffeine could be considered as a weight loss agent because it stimulates an extra flow of urine, but besides the energetic input (evident only at very large dosages), by itself, caffeine is not that potent. A cocktail of caffeine and ephedrine, however, has shown incredible properties with some diet plans for a short period. Nevertheless, the side effects of the caffeine-ephedrine combination are very dangerous in the long run, significantly altering heart rate and blood pressure. Caffeine does increase the rate of thermogenesis (heat production by the body) and may act as a minor appetite suppressant, though not in a manner that would produce visible results

Caffeine Powder


Capsicum (or chili pepper extract) is used in the supplement for its body temperature increasing capabilities which, in the theory of Phen375 should result in the burning of excess calories. Weight loss from capsicum supplementation is an old wives’ tale as is the host of other conditions chili pepper has been used for across the ages and is still being used to this day. According to, capsicum is only effective to treat pain in certain areas resulting from rheumatoid arthritis, diabetes, and a few other conditions, but only when applied to the skin in the affected area.
Dendrobium Nobile – this substance, extracted from orchids (there are hundreds of subspecies with the dendrobium designation) is purported to smoothen the digestive process and has been frequently used in Chinese traditional medicine (and more sparsely all over South Asia) for millennia. Scientific studies involving dendrobium variations have been few and less than successful, although it does help with abnormally low salivation – one of the several symptoms associated with the autoimmune condition Sjögren’s syndrome. It is not yet known if this effect stays the same in the case of healthy individuals and, if it would, then we all know that increased salivation leads to increased appetite, thus undermining the original intent of the supplement.

Dendrobium Nobile

Calcium Carbonate

Calcium Carbonate is a frequently encountered item on the labels of weight loss supplements. The official pitch for Phen375 does not actually mention how might this substance contribute to the overall action of the product. The chief medicinal use of calcium carbonate is to reduce the severity of heartburn and symptoms of indigestion by alleviating high levels of stomach acidity, a possible result of a lower intake of food when dieting.
Chromium(12% Pikolinate) – the last ingredient common to US and EU markets, chromium is an element needed in trace amounts for human survival. There are some tests involving chromium pikolinate[3] which have yielded modest weight loss benefits in humans (about one pound of body mass per month, when taking chromium orally three times a day), but other than that, it is used to keep sugar levels in check for people with diabetes.

Chromium (Pikolinate)

As mentioned earlier, the US-version of Phen375 boasts two extra ingredients than the EU-version, and the situation is unclear on what happens in other parts of the world, although Australia receives the US type. The two extras are:

Forskolin Extract

Forskolin (Coleus Forskolii Root, 10% concentration) claimed to increase AMP levels in cells. Again, forskolin is a common sight on the labels such supplements. A puzzling aspect in the case of Phen375 concerns the fact that there are no referrals to scientific studies involving one or more of its ingredients when the marketing of most other products abounds in them.[4]

There are some scientific studies[5] regarding the positive effects of forskolin; the aforementioned AMP levels translate into a better functioning of the cell in relation to hormonal signals. From the weight loss perspective, 250 mg of 10 percent forskolin twice a day has shown some promise in men, in laboratory conditions, over a 12-week period. If the dosages were known, then Phen375 could have attained some bragging rights from the inclusion of 10% forskolin in its recipe. Instead, these effects stand squarely in the realm of speculation.

Citrus Aurantium (bitter orange extract) is supposed to increase the rate at which the metabolism burns fat. All the parts of the bitter orange, even the peel, have been used in medicine recipes since ancient times, in the parts where the fruit has been grown.

The only scientifically proven benefit of the bitter orange, however, is the oil made from the peel which has been shown improve certain skin conditions. Despite its widespread use in the popular treatment of a host of gastrointestinal conditions, evidence remains limited as to its actual effectiveness. There have been two experiments involving the citrus aurantium and caffeine combination, practically “fishing” for weight loss effects, with one experiment wielding modest results and the other concluding that the particular combination is worthless.

Citrus Aurantium

First of all, reported (though rarely) side effects include increased heart rate and blood pressure, so be on the lookout for those. As it is crucial that you do not skip meals, it is recommended to devise a routine featuring four to six moderately portioned meals per day, and taking a Phen375 pill early in the morning about half an hour before your first meal, and a second pill right after your second meal, about mid-day. With this routine, plenty of exercise, and lots of water, you can expect to lose about ten pounds in the first month, and more than thirty pounds in a four-month period. That being said, if you abandon this regimen, the chances are that the lost weight will come back. We believe that this facts report speaks for itself as to the feasibility of Phen375.

Our Verdict on Phen375

Frankly, finding positive points in the case of “Phen375” is a tall order. Regarded review websites in the niche of weight loss supplements just could not find any. Even affiliates state that the pill can best be construed as a synthetic concoction, rather than a natural one. The lack of reliable information regarding the manufacturing company, a subject we have dealt with at length, along with the different components for different parts of the world does not add to its credibility. Further adding insult to injury, the lack of information regarding the quantities simply will not do. Not to mention that there is no presented scientific backing, and upon further inquiry, the claims in the case of each component are sketchy at best.
