Best Natural Phentermine Over the Counter Alternatives to Buy Online 2023

The anti-obesity medication Phentermine is not available to buy, it has to be prescribed to obese individuals by their doctor or healthcare professional. Because of this a market for phentermine over-the-counter alternatives was created. This article details the best products to purchase in terms of weight loss results and safety.

OTC Phentermine alternatives can have a profound effect on your weight loss journey. Make sure you buy the right natural diet supplement.

A lot of overweight men and women are seeking diet pills to help them to lose weight. For some of them, Phentermine may be one of the options available.

Others may be keen to use the weight loss drug but are unable to obtain it via prescription. There are other options, of course, and some of them are much better. However, a number of people see Phentermine as the most effective weight loss pill in existence.

Perhaps this is understandable. The weight loss drug has been around for a long time. It was developed in the 1950s, so it’s probably older than most people who want to use it and a lot of them may have grown up hearing its name.

You may be surprised to learn, the USA is one of the few countries that sanction the use of this particular weight loss drug. Canada and Australia are two more, but in the UK and many other countries Phentermine is unavailable because advisory bodies consider it an overly risky option for weight loss.

One way or another, a lot of overweight or obese people are seeking natural alternatives to Phentermine diet pills. Some cannot get hold of the prescription weight loss medication, others simply don’t want the risk of potential side effects.

We’ve evaluated the most popular Phentermine over the counter brands to see which of them work best and offer the most value for money.

Here are our five top natural substitutes available in store, over counter or online for 2023.

What Is Phentermine and How Does it Help Weight Loss?

Phentermine is an amphetamine drug and a Schedule IV controlled substance in the US.

It works for weight loss by stimulating the central nervous system, causing a stress response known as fight or flight. This affects the body in many ways, not all of them good.

A few of the changes Phentermine induces are faster heart rate, higher blood pressure, and suppression of appetite. There are no prizes for guessing it’s the drug’s ability to control appetite that makes it beneficial.

Like the drug speed (amphetamine sulfate), Phentermine may also make some people more active, causing them to burn extra calories as they are dashing about. 

However, the most important Phentermine benefit is hunger suppression. By controlling your appetite, it helps you to avoid strong cravings that could cause you to overeat.

Some people who use Phentermine report such a powerful loss of hunger, they often forget to eat. Needless to say, such a strong reaction to the drug is far from being healthy and has the potential to cause harm.

Some Generic Phentermine Brands – Comprehensive List

Of the following brands and generic versions Adipex (and Adipex-P) is the most common, popular and widely sold real Phentermine diet pills in the United States, Canada, UK and Australia as well as many other European countries.

Duromine is most popular in Australia and New Zealand.

  • Acxion
  • Adipex
  • Adipex-P
  • Atti-Plex P
  • Duromine
  • Fastin
  • Ionamin
  • Lomaira
  • Phentercot
  • Phentride
  • Pro-Fast
  • Suprenza

Phentermine Diet Pills: A Look at the Risks

Like most prescription medications, Phentermine can cause side effects. Some of them are so severe the governing bodies in many countries consider it too dangerous for their citizens to use.

Because it’s an amphetamine, Phentermine also poses a risk of addiction. That’s one of the reasons why it’s only suitable for short-term usage.

Some people who use Phentermine to tackle their obesity experience no side effects at all. You could call this luck or put it down to personal genetics. Either way, when you begin using the medication for the first time, there is no way to predict the way your body will respond.

Common Phentermine side effects may include:

  • Dry mouth
  • Headaches
  • Nausea
  • Dizziness
  • Vision difficulties
  • Irritability
  • Nervousness
  • Mood swings
  • Uncontrollable anger
  • High blood pressure
  • Uncontrolled muscle movements

Although all of these side effects can be unpleasant, they pale to insignificance compared to some of the more dangerous threats Phentermine may pose including psychosis, heart attacks, and strokes.

Phentermine can also cause dangerous reactions if it’s used alongside certain other drugs including duloxetine and other SSRIs and MAO inhibitors. There are many things doctors need to consider before prescribing Phentermine. 

How Do Natural Alternatives Compare to Phentermine?

Although many of the weight loss supplements that work like Phentermine leave a lot to be desired, some of the options, such as PhenQ, PhenGold, and Phen24 work incredibly well. Our evaluation of all the most popular options suggests these are the three that work best. [source]

However, Prime Shred and Leanbean are excellent Phentermine substitutes as well. They may not be marketed as natural Phentermine alternatives or have a “Phen” in their names but they both offer a comparable level of weight loss support.

Some Prime Shred and Leanbean users report levels of weight loss that are even better than the prescription drug generally provides.

One of the main differences between Phentermine and the alternatives is the method of action. Phentermine mainly controls hunger. The weight loss supplements you can replace it with do a lot of other things too, such as increasing metabolism and act as appetite suppressants to help you to burn extra calories and fat.

The top natural products you can use instead of Phentermine also offer another advantage over and above their ability to help you to lose weight – none of them share the drug’s potential to endanger health.

How We Ranked the Top Phentermine Over the Counter Alternatives

When we were evaluating all the possible good OTC Phentermine alternatives we looked at several different factors. Our main concentration was on the quality of the products, not the manufacturers’ claims.

During our ranking process, we were mainly looking at five important areas.

1. Ingredients for Weight Loss

Many natural ingredients can support weight loss. Some of them provide support in more than one area. Capsicum is a good example, it suppresses hunger and boosts metabolism as well.

To even have a chance to be in the running, a weight loss supplement needed to have ingredients with scientifically proven value. We also required them to be provided in doses similar to those used in (successful) clinical trials.

Supplements that did not have full ingredient disclosure, such as the ones using proprietary blends, went straight to the bottom of the pile.

We also wanted to see effective combinations of weight loss ingredients. Ingredients that have a good synergy, not ones that clash or impair the overall capabilities of the formulation.

One thing we did not want to see was the overuse of stimulants. We had to reject a lot of diet pills for doing that.

Although stimulants like caffeine can be valuable supplement ingredients, when you include them in overly high doses or use too many of them, it can make the people who use the supplement feel jittery and ill. Moderation is the key and that’s what we like to see.

2. Realistic Claims for Losing Weight

The manufacturers who produce all the most credible weight loss supplements let their customers know the type and range of benefits they can expect. They don’t make a lot of unrealistic claims of fantastic weight losses of 20 or more pounds a week.

Nor do they try to mislead anyone into believing weight loss is possible without a low calorie diet and exercise.

3. Good Customer Reviews for OTC Diet Pills

When we were looking for other diet pills or the best supplements to use instead of Phentermine pills, we spent a lot of time reading customer reviews.

Admittedly some of the options did not have any customer reviews. That meant there was a lack of feedback about their ability to work. We moved them to the bottom of the pile as well.

We wanted to see good reviews and plenty of them, written by people explaining the way the appetite suppressants helped them. Comments like “Great!” and “Really Works” aren’t informative. We wanted to know how much weight was lost and how quickly it went.

Comments about product potency, ability to control hunger, and provide energy and other benefits were very helpful. So were comments about side effects. When we saw any of them… bottom of the pile.

4. Reasonable Pricing

Some manufacturers of natural weight loss supplements make their weight management products ridiculously expensive. Nobody should be expected to pay $100 or more per month for phentermine alternatives.

We set the top bar at $80 because supplements of that price level should not be beyond the budget of the average person who is struggling to lose weight.

All five of the Phentermine over the counter alternatives we chose cost less than this.

Our five natural over the counter Phentermine diet pills also come from manufacturers who allow their customers to make additional savings by taking advantage of discounts and/or special deals such as buying two bottles to get a third one free.

We would never rank a product on something like that but it’s always nice to see.

5. Money-Back Guarantee

Money-back guarantees are important. We like to see them and would never recommend any product that does not have one. It builds trust with new customers and keeps things fair by giving customers a chance to ask for a refund if they feel the product has let them down.

We don’t expect any of our top 5 Phentermine alternatives will let anyone down. If we did, they wouldn’t be here, but we still require them to have money-back guarantees.

Best Phentermine Alternative Supplements – Concluding Thoughts

Phentermine is a prescription appetite suppressant that works for most people who can obtain it. Unfortunately, it can be addictive and has the potential to cause severe side effects.

The best natural alternatives are a different matter. Due to the use of carefully selected ingredients, they can help you to lose weight like Phentermine, or better, without posing any of the risks.

However, regardless of whether you are using Phentermine or an alternative drug or natural supplement, the role of diet pills is only supportive. Even the best diet pills will only assist the effort you are already making with diet and exercise.

Diet pills work, but you need to put in some effort too. Forget any ideas you may have about finding a magic weight loss pill.

Finding a diet pill that works like Phentermine can be challenging. A lot of the options that appear very promising are not up to the task. Many diet pills are made to look more promising than they are due to clever marketing hype.

The five options we provide in this article are capable of providing unparalleled levels of weight loss support. When you use them correctly and put in a little effort. They can help you to get where you need to be more quickly than you could on your own.

They are excellent options for anyone who needs a good Phentermine alternative or simply wants to lose weight faster. All of them have worked for thousands of other people. They can do the same for you and offer excellent value for money. Each of them also has a money-back guarantee. So you can buy them and try them with nothing to lose.

Phentermine FAQ’s

Can anyone buy real Phentermine over the counter or online?

No, your body weight status has to be considered very overweight or obese. Your BMI (body mass index) should be over 27. It is only available via doctor’s prescription.

Do natural alternatives to Phentermine work as well as the prescription medication?

Some of the over counter (OTC) diet pills and natural weight loss pills are just as effective at helping men and women to lose weight and prevent future weight gain. Not only can natural diet pills provide appetite suppression but also burn body fat, reduce body fat and help boost metabolism.

Is Adipex the same as Phentermine and can I get it over-the-counter?

Adipex (and Adipex-P) is a brand name. So is Ionamin and Duromine. Adipex is not available over the counter. There are natural alternatives that are available to buy over the counter without prescription such as PhenQ, PhenGold and Phen24.
