Phentramine-RX 50 Review 

Despite their best efforts during every workout, many people simply fail to achieve their body goals. In most cases, the real reason for this is a bad diet plan. It is something many take for granted and it usually backfires in the worst possible way.

Phentramine-RX 50 Readers: Noom weight loss app is offering our readers a 14-day trial for a limited time. Click here for this special offer.

No matter what your goal may be, whether it's building muscle or losing weight, you still need the right nutrients and a good eating plan. Today, we will review a product from Desirable Body that could make things easier, helping you lose weight in a more profound way.

Phentramine-RX 50 contains a formula made up of active compounds that help you burn fat, control your appetite, and increase your basal metabolic rate. Its name is similar to the prescription pill Phentermine, but Phentramine-RX 50 is available over the counter. Besides its fat burning properties, it is also designed to enhance focus and improve energy levels, which is always a great thing to have when trying to lose weight.

Claims like these always sound appealing but how true are they really? We are going to carefully inspect Phentramine-RX 50, summarize the results and give you all the necessary information about this product. Just read on!

How Phentramine-RX 50 Works

Phentramine-RX 50 works in various different ways, providing a powerful combination of ingredients that are linked to increased metabolism levels, fat burning, and appetite suppression. Phentramine-RX 50 especially targets the basal metabolism rate, speeding it up and allowing the user to receive greater benefits from his diet and exercise program.

These properties should help you burn fat with ease. No annoying cravings, no shortage of energy, and no lack of results.

Phentramine-RX 50 Ingredients

Unfortunately, Phentramine-RX 50 is another diet pill that offers a proprietary blend of ingredients.

Supplement companies use proprietary blends to combine different ingredients, providing no clear indication of the dose of each ingredient. This increases the risk of side effects and inefficiency, as we don’t know the exact dosages.

Here is the list of ingredients found in Phentramine-RX 50:

  1. Caffeine – Is a very well researched ingredient that is found in many popular weight loss supplements today. One thing's for sure, Caffeine will increase your energy expenditure instantly, kick-starting your whole body into being more active. Caffeine can also potentially reduce the feeling of hunger and desire to eat (1). The only thing to keep in mind is that a higher dose of caffeine combined with other weight loss stimulants could result in side effects such as anxiety, insomnia, nausea, increased blood pressure, and other problems (2).
  2. Naringin – Is the predominant flavonoid in grapefruits, which is what provides a better taste. Naringin might be the healthiest ingredient on this list! Having anti-carcinogenic and antioxidant abilities, this ingredient plays a key role in the prevention of inflammation and diseases (3). Naringin is also known for its ability to enhance the effects of other compounds found in dietary supplements (4).
  3. L-Tyrosine – Is an essential amino acid that is believed to increase the production of thyroid hormones, which have a direct correlation to weight loss and appetite (5). In the case of Phentramine-RX 50, the manufacturers are strictly targeting the production of thyroxin, which might lead to an increase in the metabolic rate. However, studies have not found any significant impact on weight loss or diet(6).
  4. Vitamin B6 (Pyridoxine) – Is a water-soluble nutrient that is part of the B vitamin family. All B vitamins, including Pyridoxine, help support adrenal function, help maintain a healthy nervous system, and are necessary for key metabolic processes (7). Vitamin B6 is included in this fat burning formula since it acts as a coenzyme in the breakdown and utilization of carbohydrates, fats, and proteins. This process is believed to increase the metabolic rate by again enhancing the thyroid hormone function (8).
  5. Acai Berry – Is a natural ingredient that is extracted from palm trees of South and Central America. Acai Berry has a wide range of health benefits (9). The most valuable one includes the ability to reduce any risk of cardiovascular disease by enhancing certain conditions and removing risk factors. Risk factors include high cholesterol levels, obesity, stress, insomnia. Acai Berry has virtually no side effects (10).
  6. L-Tryptophan – Another essential amino acid that our body cannot produce on its own. In the body, L-Tryptophan is converted into serotonin and is generally used to improve mood, well-being, and energy expenditure. However, there is very little evidence to support these claims (11).

Ingredients Summary

Phentramine-RX 50 relies on several stimulants in order to produce any desired weight loss effect. The main problem is the lack of proof that would confirm that mixing all these ingredients together is both safe and effective. However, there are some quality ingredients in Phentramine-RX 50, such as Naringin and Acai Berry, that have extraordinary health benefits. Although there is limited scientific research on their role in weight loss, this is an average concoction of ingredients.

Phentramine-RX 50 Side Effects

There have been some noticeable side effects linked to Phentramine-RX 50, which the company hides. In the first place, you would purchase this dietary supplement for its well-rounded properties that would help with weight loss. Instead, however, it appears that some of the side effects experienced resembled caffeine overexposure.

Caffeine can leave you feeling a bit anxious and shaky. Another thing that appeared was jitteriness. Jitters are not considered to be harmful, although they can be disconcerting for those who have never experienced them.
The good news is that there are many customers who have not reported any of these side effects at all, so this may well only be the case for caffeine-sensitive individuals.

Related to Phentramine-RX 50: Phentaslim Review (New 2020) - Why we rate it as #1


After looking at the facts, we can only say that Phentramine-RX 50 is a supplement of rather questionable quality. It features a few truly mediocre ingredients among a couple of useful ones. In the end, this product will most likely fail to deliver the promised results. In our opinion, Phentramine-RX 50 needs a lot of improvement.

With no money back guarantee, the decision is clear. If you’re looking for an effective diet pill, look elsewhere since Phentramine-RX 50 is most likely not the solution.
