review of Phenaprin

PhenAprin is a diet pill manufactured in the USA for SutraHealth. The company markets its product exclusively via Amazon.

When you see an over-the-counter (OTC) diet pill with a name that begins with “Phen,” you are looking at a supplement that’s designed to attract people seeking Phentermine or a safer alternative.


Effective Appetite Control: PhenAprin is designed to help reduce hunger cravings and suppress appetite, which can lead to a lower calorie intake and aid in weight loss efforts.
Energy Boosting Capabilities:
 Besides appetite suppression, PhenAprin contains ingredients that help boost energy levels. This can be particularly beneficial for maintaining physical activity levels and improving overall energy throughout the day.
Metabolism Enhancement: PhenAprin is formulated to not only suppress appetite but also to enhance metabolic rate. A faster metabolism can increase the body’s ability to burn fat, contributing to weight loss.
Mood Enhancement: Some ingredients in PhenAprin may have mood-enhancing properties, which can be helpful when dealing with the stress and mood swings often associated with dieting and weight loss regimens.


Side Effects: PhenAprin can cause side effects in some users. Common issues might include jitteriness, insomnia, increased heart rate, headaches, and gastrointestinal disturbances such as nausea or constipation.
Amazon Diet Pill: Some of the diet pills and supplements have questionable efficacy.


PhenAprin is a appetite suppressant that is presented as as natural Alternative to Phentermine. In my opinion PhenQ is better weight loss product as it offers fat burning, fat blocking and appetite control. Read more on PhenQ

Phentermine is a popular prescription appetite suppressant that can present dangerous side effects and has the potential to cause addiction.

Phentermine pills are white with distinctive blue flecks running through them. PhenAprin shares this design.

This review provides a science-based evaluation of PhenAprin and its key ingredients. I am going to take a look at the benefits they may provide along with any side effects their use may entail. I will also take a look at the experiences being shared in PhenAtrim customer reviews. If you want to know the pros and cons of using PhenAprin diet pills, you have come to the right place.

Product Description: What Is PhenAprin?

PhenAprin is primarily marketed on its ability to boost energy levels and metabolism. As you would expect for a diet pill that mimics Phentermine, PhenAprin is also designed to control hunger cravings.

Most OTC diet pills are designed to provide the same three benefits. Some of the best options can do considerably more. However, if PhenAprin does what it’s supposed to do, its ability to control hunger will make it easier to follow a low-calorie diet without having to worry unduly about hunger and all the misery it brings.

By boosting energy levels and metabolism, the supplement may also prevent diet-related fatigue and raise the metabolic rate sufficiently to help its users burn more calories per day than they could by diet and exercise alone, helping them lose weight more quickly.

Who Is Phenaprin For?

The choice of name and tablet design makes it pretty clear that PhenAprin is intended to be enticing to people who are interested in using Phentermine or want to find a more acceptable alternative.

Like the prescription pill that obviously inspired its creation, PhenAprin is primarily for people who are interested in losing weight and need something to speed up the process while also helping them deal with common obstacles like weariness and hunger.

PhenAprin Ingredient Profile

Each (1-tablet) serving of PhenAprin provides the following six ingredients:

  • L-Phenylalanine (230 mg)
  • L-Carnitine (85 mg)
  • Taurine (75 mg)
  • Theobromine (70 mg)
  • Caffeine Anhydrous (70 mg)
  • 7-Keto DHEA (10 mg)

The pills also contain a surprisingly large number of additional, non-active, ingredients that help bind them together, provide color, and even assist with flavor:

  • Dicalcium phosphate
  • Microcrystalline cellulose
  • Stearic acid
  • FD&C Blue #1
  • Croscarmellose sodium Magnesium stearate
  • Silicon dioxide

That’s already a lot of extras but there is one more: Blue Sugar Spheres.

This ingredient appears to be some form of sweetener. It contains sugar, sugar syrup powder, and polyvinylpyrrolidone.

None of these inclusions give me a warm, rosy feeling. There are a lot of chemicals involved. However, FD&C #1 is the ingredient choice I find most concerning because some experts have raised concerns about its toxicity and potential to cause cancer.

An FDA health advisory notice from 2003 is equally concerning. The FDA issued it after tube-fed patients in hospitals died are a result of being fed food tinted with FD&C Blue #1.

Despite the concerns, FD&C Blue #1 continues to be on the FDA’s list of approved food additives.

PhenAprin Ingredient Analysis

All six of the key ingredients have science-backed abilities in various areas relating to weight management. However, there are many alternative options, such as green tea and cayenne pepper extract, that have far superior credentials as diet pill ingredients.

But let’s put a cap on the cynicism for now and examine the benefits each of the six PhenAprin ingredients brings to the table.

L-Phenylalanine (230 mg)

L-phenylalanine is an essential amino acid that plays a role in various bodily functions, particularly in the production of neurotransmitters like dopamine and norepinephrine. These neurotransmitters are important for mood regulation and can potentially influence eating behaviors.

Limited research suggests supplements that increase levels of L-Phenylalanine in the body may have the potential to reduce food intake by stimulating the release of cholecystokinin. Although its role in reducing hunger requires further study, there are strong indications cholecystokinin may be a satiety hormone.

L-Carnitine (85 mg)

L-carnitine is an amino acid that’s a key ingredient in many sports supplements and, to a lesser extent, in diet pills as well.

One of the many things L-Carnitine does is aid the transport of fatty acids from the blood into the mitochondria, where the cells can use them for energy.

By helping the body burn fatty acids more efficiently, L-carnitine may help limit the amount of excess fatty acids the body stores as fat.

Regardless of the dynamics involved, some research suggests supplements that provide L-carnitine can be useful for reducing body weight and BMI (body mass index).

Taurine (75 mg)

Taurine is a common inclusion in diet pills and energy drinks. It’s an amino sulfonic acid that serves several roles in the body, particularly in cardiovascular function, electrolyte balance, and central nervous system functioning.

In the context of weight loss supplements, taurine is valued primarily for its potential to enhance physical performance and energy levels. It may help reduce fatigue and improve endurance, which can be beneficial for people engaging in regular exercise as part of a weight loss program. 

Theobromine (70 mg)

Theobromine is a mild stimulant that occurs naturally in chocolate. It appears to have mood-boosting capabilities and is often associated with the “feel good” effect many people experience due to eating chocolate.

As a stimulant, theobromine is milder than caffeine but may still provide a modest energy boost. Additionally, theobromine possesses vasodilatory effects, which can improve blood flow to the muscles, potentially enhancing exercise performance. 

Overall, theobromine’s benefits are modest at best. It’s not by any means a power ingredient but it’s gentle on the body and unlikely to cause side effects.

Caffeine Anhydrous (70 mg)

More popular than theobromine, caffeine is one of the most commonly used stimulants in the world. The dose PhenAprin provides matches the caffeine hit you would get from a single shot of espresso.

That’s enough to provide benefits such as higher energy levels and sharper mental focus but not high enough to cause side effects for the average person.

Research shows caffeine also supports improvements in fat burning by increasing thermogenesis. This is a natural process that boosts metabolism by causing the body to become warmer and lose extra energy as heat.

7-Keto DHEA (10 mg)

Also known as 7-Keto or 7-oxo-dehydroepiandrosterone, 7-Keto-DHEA is a supplement that is believed to have potential benefits for metabolism and weight loss. It is a derivative of dehydroepiandrosterone (DHEA), a hormone produced naturally in the body.

Unlike DHEA, 7-Keto-DHEA does not actively interact with sex hormones and does not increase their levels in the blood when taken as an oral supplement. However, the truth is this ingredient has questionable value as a diet pill inclusion.

The results of a systematic review exploring the impact of 7-Keto-DHEA on body weight do little to enhance the ingredient’s reputation because the clinical studies available were giving mixed results, stressing the need for further, in-depth investigation.

PhenAprin Dosage and Potency Evaluation

As is often the case with dietary supplements, new users are advised to proceed with caution. SutraHealth suggests beginning with just one tablet per day, taken in the morning with food.

If no ill effects become apparent during the first week, the dose ups to one tablet, two times per day from day eight onward. The label on the bottle does not specify the best time to take the second pill but I would recommend taking it with lunch. Due to the presence of stimulants in the formulation, taking it too late in the day may have the potential to interfere with sleep.

As far as product potency goes, the doses per tablet are okay. Even when taking two tablets each day, the caffeine content is still quite low in comparison to many similar supplements. Unless you are hypersensitive to it, caffeine-related side effects should not be an issue.

PhenAprin Safety and Side Effects

Several of the ingredients in PhenAprin have the potential to cause side effects, particularly digestive disturbances. Although caffeine is often associated with side effects such as jitters, nausea, headaches, and high blood pressure, it only affects people in this way if they are unusually sensitive to it or consume it in overly high doses.

L-phenylalanine can cause nervousness and anxiety, heart palpitations, and jitteriness. Again though, adverse effects such as these are more typical with very high doses. However, it can interact with some medications, including antidepressants, and has the potential to aggravate certain medical conditions.

7-Keto DHEA is another potential bad boy. It may cause oily skin, acne, insomnia, heart palpitations, and sleep disturbances. Although it does not convert to active sex hormones like the body’s natural DHEA is prone to do, 7-Keto DHEA still can affect the endocrine system, disrupting normal hormonal balance.

Individually, in the doses provided, none of the ingredients are likely to cause too many problems. Collectively, it’s hard to say because so many of them have the potential to cause similar issues such as heart palpitations and digestive disturbances.

With this in mind, If you are considering using PhenApin for weight loss, I suggest you discuss your intentions with a medical professional first. This is especially important if you have existing health issues or would need to use PhenAprin alongside medication.

PhenAprin Consumer Insights

Customer reviews are plentiful but a pretty mixed bag with some people praising the supplement’s ability to control hunger and promote weight loss, while others say it did nothing for them at all. However, it’s worth noting most of the negative reviews mention a variety of side effects including headaches, mood swings, and even weight gain.

PhenAprin Usage Costs and Value for Money

PhenAprin costs just under $40 per bottle. That’s not overly expensive but looking at the formula and reading about customer experiences, I question its ability to provide good value for money and, like most diet pills that are exclusive to Amazon, there is no opportunity for a refund because there is no money-back guarantee.

PhenAprin Review Conclusion

PhenAprim is a gimmicky diet pill that’s designed to be a dead ringer for Phentermine tablets. However, the flecks of blue in the pills are made possible by a controversial ingredient that may have the potential to present serious health risks. Its presence is reason enough to steer clear of PhenAprin and choose an alternative diet pill instead.

As for the formula, the key ingredients have merit but, except for caffeine, none of them have abilities that are strong enough to make them stand out in a crowd.

Customer reviews suggest PhenAprin may work for some people but is equally likely to provide nothing more than disappointment, accompanied by a risk of unpleasant side effects. I hate to end this review on a sour note but, if you are considering taking a chance on PhenAprin, my advice is don’t do it. There are several safer, more powerful options you could take a chance on instead and all of them have money-back guarantees.
