Potential Benefits of Taking this Dietary Supplement

Before listing the possible benefits associated with taking this dietary supplement, it is important to point out that although PhenObestin 37.5 is marketed as a non-prescription phentermine alternative, the reality is that it is not truly an alternative. Currently, there are no over the counter (OTC) weight loss pills that have been approved as a prescription-free alternative to phentermine and related diet drugs that have been FDA-approved to treat obesity.

Regarding the claims of PhenObestin’s benefits, they are as follows:

  • Appetite suppression
  • Hunger control
  • Fat burning
  • Enhanced mood
  • Improved blood circulation
  • Sustained energy

PhenObestin 37.5 Ingredients List

When this PhenObestin 37.5 review was written, the white with blue spec tablet contained:

  • Phenylethylamine HCl
  • Thobromine Anhydrous
  • Yohimbine HCl 99%
  • Methylsynephrine HCl
  • N-Methyl-B-Phenylethylamine HCL
  • Synephrine HCL, and Caffeine Anhydrous

As you may have noticed based on the above list of ingredients, PhenObestin 37.5 contains only stimulants. As such, it is not out of the realm of possibilities that it will increase mental alertness and boost metabolism levels, which could help prevent fatigue and assist a user in getting the most out of there workouts.

For instance, there have been clinical studies that have suggested that caffeine can help stimulate metabolic rate and lead to greater oxidation of fat.

That said, there is no clinical evidence that proves taking PhenObesting 37.5 will lead to weight loss, with aid in long-term weight management efforts or that it is safe to take.

Stimulant Overload

What is alarming about the above list of ingredients is the fact that every single one of them is a stimulant. This automatically raises a lot of red flags and calls the safety of this product into question. The simple reason being, multiple stimulants increases the potential occurrence of adverse side effects, especially for individuals with certain medical conditions, individuals who may be taking certain medications, and for anyone who has sensitivity to stimulants.

Some common side effects associated with stimulants include, but are not necessarily limited to:

  • Rapid heartbeat
  • Jitters
  • Sleeplessness
  • Anxiety
  • Headache
  • Stomach upset
  • Mood changes
  • High blood pressure

Considering PhenObestin 37.5 contains so many stimulant ingredients, this diet pill may not be the best choice for individuals who are sensitive to stimulants as the risk of potential unwanted side effects may outweigh any possible benefits. Since this is the case, it would be wise for these individuals to avoid this product altogether.

Also, keep in mind if this is an OTC weight management aid that interests you, and you do not have a problem with stimulants, it would still be in your best interest to avoid ingesting other stimulant products (e.g. cola, coffee, caffeinated tea, energy drinks, etc.) while taking it to reduce the risk of adverse effects.

Finally, if you have been diagnosed or are being treated for a medical condition or you are pregnant, nursing a baby or planning on becoming pregnant, you should first speak with your healthcare provider before taking PhenObestin 37.5. Never make the assumption that a dietary supplement isn’t dangerous simply because it can be purchased without a doctor’s approval or because a manufacturer claims the formula is safe.

Update – January 2020: PhenObestin 37.5 has likely been discontinued. The product is no longer sold online by the manufacturer or on Amazon. Although it isn’t available for purchase, if you were hoping to find a non-prescription diet pill that offers support with mental alertness, energy enhancement, metabolism boosting, and hunger control, there are other OTC weight management aids that you can investigate and try.  

Phen Caps

The official product site states that Phen Caps is “the official alternative to Phentermine.” It has been designed for individuals who would like to experience the weight loss benefits of prescription drugs but who do not want the harsh side effects that go along with it.

According to the official site for Phen Caps, the product states that Phen Caps are meant for a person who is not able to obtain a prescription for weight loss medication; who cannot bear the side effects of these medications; who require some extra assistance when their weight loss drugs wear off; and for those who are taking diet medications and would like an extra boost.

When this review was written, a 30-day supply of Phen Caps (60 capsules) cost $49.95 plus shipping and came with a 30-day 100% money-back guarantee.

The ingredients in the Phen Caps formula are not anything revolutionary or special. In fact, these ingredients can be found in many other non-prescription Phentermine alternative diet supplements on the weight loss market. That being said, the ingredients are: Phenylethylamine (PEA), Caffeine, Theobromine, Caralluma fimbriata, Synephrine, Methylsynephrine, L-Carnitine, Red Raspberry Ketones, Crateagus spp. Extract.

While a few brief details are provided for each of these ingredients on the official site, what is disappointing is that no citations to studies were included to backup any of the claims that were made. Like so many other diet pill product website, the one for Phen Caps goes so far as to provide pictures and product information, but doesn’t provide any solid proof to authenticate the information it has provided.

Something else that is concerning is that while the manufacturer claims Phen Caps has “no side effects”, this is not true. While it may not produce the same risk of side effects as prescription weight loss pills, it still carries a risk of adverse effects, especially since it contains both caffeine and synephrine. The FDA has cautioned that synephrine, a stimulant found in bitter orange, can increase the risk of adverse cardiovascular effects, such as high blood pressure, fainting, heart attack, and stroke, and that this risk is amplified when synephrine is combined with caffeine.

Moreover, this product contains multiple stimulants, which increases the risk of insomnia, jitters, anxiety, mood swings, upset stomach, headache, etc, especially in individuals who have sensitivities to these substances.

Additionally, it is also troubling that the official site claims that Phen Caps may be right for those who are currently taking other weight loss medications. This implies that you can take Phen Caps simultaneously with your prescription diet drugs, which might not actually be safe. Definitely speak with your healthcare provider before taking this product, and especially before combining it with any medication (weight loss or other) or supplement.
