Best Phentermine Over the Counter Alternative Review and Rating Criteria

Creating a comprehensive review of over-the-counter alternatives to phentermine requires careful consideration of various factors. Here are five criteria that we have used to evaluate and rate the OTC Phentermine alternatives and diet pills.

Efficacy: This is perhaps the most crucial factor. Does the Phentermine over the counter alternative product demonstrate a significant effect on weight loss in clinical trials or scientific studies? Remember that individual results can vary based on factors like lifestyle and genetics.
Safety: Evaluate the safety profile of each product. Are there any reported side effects, and if so, how severe are they? Is the product safe for long-term use? It's also important to consider whether the product has any contraindications or potential interactions with other substances.
Ingredients: What active ingredients does the over the counter Phentermine alternative contain, and what is known about these ingredients? Are they backed by scientific research? Are the ingredients natural or synthetic, and does this matter for the intended audience of your blog?
Ease of Use: How is the product administered, and how often? Is it easy to incorporate into daily routines? This can greatly impact a person's adherence to the product.
Price and Availability: Is the product reasonably priced and easily accessible for your readers? Consider factors like whether a prescription is needed, the cost per dose, and where the product can be purchased.

While Phentermine over-the-counter alternatives can aid weight loss, they should not replace a balanced diet and regular exercise. It's also important to consult a healthcare provider before starting any new supplement regimen.

What Is Phentermine and How Does It Work?

Phentermine (HCL) is a prescription-only diet pill that has been used to help people with obesity manage their weight loss for the past fifty years. It works by reducing appetite and increasing energy levels which, in turn, leads to reduced calorie intake and increased physical activity.

Phentermine is a central nervous system stimulant. It works by activating certain neurotransmitters in the brain, such as dopamine and norepinephrine. These chemicals are responsible for controlling appetite, energy levels, and other metabolic processes.

The active ingredient in Phentermine is phentermine hydrochloride. A form of amphetamine, it's a Schedule iv Controlled substance with a potential for addiction and abuse. Consequently, it's only available with a doctor's prescription.

Phentermine can be dangerous if misused and it comes with a long list of side effects. It's not suitable for everyone and its use requires strict medical supervision.

The Phentermine (Adipex) dosage is typically 37.5 mg

Phentermine Brand Names

Here are the most common and widely prescribed phentermine brands.

Adipex (United States)
Adipex-P (37.5 mg)
Duromine (Australia)
Atti-Plex P
Fastin
Ionamin
Lomaira
Phentercot
Phentride

Phentermine Eligibility and Suitability

The use of Phentermine is restricted to people who are medically eligible and deemed suitable. People who suffer from certain medical conditions, such as high blood pressure, may be ineligible for a prescription even if they meet the necessary criteria.

People who are using certain other medications may also be unable to get a prescription due to the risk of unfavorable interactions.

In general, candidates for Phentermine must:

Be over 18 years old
Have a body mass index (BMI) of 30 or higher
Have tried other weight loss methods in the past without success
Be assessed by their doctor as suitable for this type of treatment

People who are overweight but not obese (BMI 27-29) may also be eligible for a Phentermine prescription but only if they have medical conditions, such as type 2 diabetes, that may become worse due to their overweight condition.

If you meet these criteria, your doctor may prescribe Phentermine as part of an intensive lifestyle change program that includes a healthy diet and regular exercise.

However, Phentermine is only a short-term obesity treatment with a maximum prescription availability of 12 weeks. Natural diet pills do not have such restrictions. That's one of the reasons they are so popular.

Phentermine Side Effects and Dangers

Phentermine is a powerful prescription drug that can cause some dangerous side effects if used inappropriately. The most common side effects include:

Increased blood pressure and heart rate
Dizziness
Drowsiness
Headaches
Insomnia
Dry mouth
Nausea
Allergic reactions

More serious side effects can include chest pain, heart palpitations, heart attacks, and strokes. The drug also has the potential to be addictive.

It's side effects such as these that help fuel the demand for natural phentermine alternatives. Many people who are using dietary supplements like PhenQ are doing so due to bad experiences with prescription Phentermine.

Other users have simply heard of the risks prescription Phentermine pills can present and have decided to play it safe and use Phentermine substitutes instead.

What Other Diet Pills Work like Phentermine?

Here are some examples of other prescription and over-the-counter diet pills that work similarly to Phentermine as appetite suppressants:

Benzphetamine (brand name Didrex) - a prescription stimulant drug that suppresses appetite by acting on dopamine and norepinephrine.
Diethylpropion (brand name Tenuate) - a prescription appetite suppressant that stimulates the release of norepinephrine.
Phendimetrazine (brands Bontril, Melfiat) - a prescription weight loss medication that acts as a sympathomimetic amine to reduce appetite.
Orlistat (brand name Xenical) - a prescription drug that reduces fat absorption in the gut to promote weight loss.
Lorcaserin (brand name Belviq) - a prescription serotonin 2C receptor agonist that acts on appetite centers in the brain.
Naltrexone/bupropion (brand name Contrave) - a combination prescription drug that impacts appetite regulation.
Over-the-counter options like glucomannan, Garcinia cambogia, green tea extract, cayenne pepper, and African mango extracts may also help curb appetite.

What to Look For in Natural Phentermine Alternatives

OTC Phentermine alternatives need to meet the following criteria:

Provide natural ingredients that are clinically shown to aid weight loss
Have no known side effects
Suppress appetite and cravings
Boost energy and focus for workouts
Be manufactured in an FDA-registered and/or GMP-certified facility
Have plenty of positive customer reviews and testimonials

Although it would be unfair to judge any brand of weight loss pills on their returns policies, it's true to say all the best OTC Phentermine alternatives have money-back guarantees.

With certain options, you may need to buy two or more bottles to get the guarantee, but the option is still there.

Ingredients to Seek Out

Many natural ingredients have associations with weight loss. However, not all of them have been proven to be effective in clinical trials. If the science is not there to support their abilities, it's not worth taking the risk. Especially when there are so many ingredients that do have credible scientific credentials.

Ingredients to look out for include:

Nopal

Nopal (Caralluma fimbriata) is a cactus that's widely found in Mexico. It contains high levels of fiber and has been shown to reduce appetite, increase fat burning, and reduce blood cholesterol levels.

However, nopal tends to get the most attention for its powerful abilities as an appetite suppressant.

Research shows overweight men and women who took nopal supplements for 60 days felt less hunger. Data from the study also shows nopal supplementation also resulted in decreases in waist circumference. [1]

Chromium Picolinate

Chromium picolinate provides the mineral chromium in a form that's very easy for the body to process and digest. It's one of the most popular ingredients in OTC weight loss pills and Phentermine alternative brands.

Chromium helps regulate insulin and blood sugar levels. Its ability to do this can help prevent rapid fluctuations in blood sugar that may potentially trigger cravings for sugar and carbs.

Some research suggests Chromium Picolinate may further support appetite control by increasing satiety. [2]

Caffeine Anhydrous

Caffeine anhydrous is a form of caffeine derived from coffee beans. It's fast-acting, making it perfect for those who need to feel energized quickly before hitting the gym or working out at home.

Caffeine can also help reduce feelings of fatigue and mental fog, which can be especially beneficial during low-calorie dieting phases when energy levels are likely to dip.

One of the more versatile ingredients of OTC Phentermine alternatives, caffeine also offers modest value as an appetite suppressant. However, research suggests this popular stimulant has far greater value as a metabolism booster and fat burner. [3]

Guarana

Guarana is a climbing plant native to the Amazon rainforest. Its berries are a potent source of caffeine. However, it releases caffeine into the body slowly. So, although the benefits are not so quick to appear in comparison to Caffeine Anhydrous, they will hang around a lot longer.

L-Choline

L-Choline is a nutrient found in eggs, fish, and dairy products. Studies show supplements that increase levels of L-Choline in the body can provide rapid fat loss. [4]

Glucomannan

Glucomannan is a dietary fiber extracted from the root of the konjac plant. It's often used as a natural appetite suppressant because it expands in the stomach and creates a full feeling that makes it easier to eat less at meal times and avoid between-meal snacking.

The European Food Safety Authority (EFSA) has examined data from all the most important clinical trials and confirms Glucomannan's value as an appetite suppressant and natural aid to weight loss. [5]

Green Tea Extract

Green tea is one of the most popular diet pill ingredients. Research shows the antioxidants it provides aid the weight loss process by increasing metabolism via thermogenesis. By doing this, the antioxidants in Green Tea Extract increase energy expenditure encouraging the body to start breaking down body fat and burning it as fuel. [6]

Cayenne Pepper

Most of the best alternatives to Phentermine diet pills include cayenne in their formulations. It's very popular. That's not surprising, research shows the capsaicin cayenne provides can help you lose weight in several ways. There's a mountain of research that supports using cayenne both as an appetite suppressant and a thermogenic fat burner.

A study available to read online in Bioscience Reports reveals dietary capsaicin further supports fat loss by enhancing lipolysis, activating brown adipose tissue (BAT), and encouraging favorable changes in the gut microbiome.

In addition to doing all these things, capsaicin activates fat-burning enzymes and inhibits adipogenesis (fat storage), helping to prevent further weight gain [7]

Bitter Orange

Bitter Orange Extract (Citrus Aurantium) is a citrus fruit that provides several powerful fat-burning stimulants, most notably synephrine.

Research shows synephrine enhances fat oxidation during exercise. However, the level of benefit it offers to sedentary individuals continues to be unclear. [8]

Green Coffee Bean Extract

Green Coffee Bean Extract comes from coffee beans that are still in their raw state and maintain their natural abundance of chlorogenic acid.

Chlorogenic acid increases metabolism. It also controls blood sugar and insulin in a similar way to Chromium. Research shows chlorogenic acid can significantly reduce visceral fat (belly fat). [9]

L-Carnitine

L-Carnitine is an amino acid that plays an important role in fatty acid oxidation and aids energy production at the cellular level. In addition to doing these things, it also influences mood for the better, offering value to people suffering from depression. [10, 11]

Garcinia Cambogia

Garcinia Cambogia is a tropical fruit. Its rind provides hydroxycitric acid (HCA), which offers value both as an appetite suppressant and as a fat burner.

Research is highly supportive of using Garcinia Cambogia extracts to target abdominal fat. [12]

Things to Watch Out For When Considering Phentermine Alternatives OTC

Although you will not need to worry about such things if you choose any of the natural supplements we recommend on this page, there are a few additional factors to consider if you decide to go off in search of other Phentermine over the counter brands to use instead.

Here are three things to avoid when choosing a Phentermine over the counter brand:

#1 - Proprietary Blends That Hide Ingredient Inclusion Rates

Although ingredient suppliers often use proprietary blends to make it harder for competitors to copy their supplement science, when diet pill manufacturers combine all their diet pill ingredients into a proprietary blend, it's a cause for concern.

Companies that do this often do so to make it impossible for customers to discover vital ingredients are not present in sufficient amounts. The same tactic allows them to disguise the fact cheaper ingredients are running the show.

It's quite common for manufacturers to load their diet pills with caffeine and/or other stimulants to boost metabolism and reduce body weight. Although people taking stimulant-heavy options may find they are burning fat faster, they may also be hit with jitters, nausea, anxiety, and other side effects.

When manufacturers are open about the ingredients they are using and their weights and measures, it helps show their integrity. More importantly, it provides potential users with a starting point should they decide to investigate the ingredients and the things they can do.

#2 - Products with unknown or untested ingredients

The diet pill market is often flooded with products that contain ingredients no one has ever heard about. Such ingredients are mostly untested and may be dangerous. With so many proven ingredients to choose from, such as Cayenne, Nopal, and Green Tea, there is no need to take a risk on untested ingredients, yet a surprisingly large number of supplement manufacturers do.

#3 - Companies with Auto-Billing or Hidden Terms and Conditions

When selecting a diet pill, it's wise to check out the company behind the product before you buy. It's especially important to read their terms and conditions page.

Companies that use auto-billing (or similar practices) are often unreliable and/or unscrupulous. Too many people learn this lesson the hard way.

More often than not, site visitors are presented with the offer of a free trial with nothing but a small charge for postage to pay.

Although such offers initially look good, the terms and conditions page generally makes it clear the trial period is only a few weeks. To avoid being charged for the pills they got on via the trial and prevent future additional charges and shipments, customers need to contact the company in question and cancel the auto-ship agreement.

Most people never read the terms and conditions and sites that favor this type of underhand tactic do not encourage people to do so. Customers only realize when they see fees being applied to their cards.

Reputable manufacturers that sell Phentermine weight loss pills or substitutes never resort to such practices.

How to Save Money When Buying Phentermine Alternatives?

All the top Phentermine substitutes cost less than $100 a month to use. Unless you are on a really tight budget, that's not going to break the bank.

However, in all cases, it's possible to reduce usage costs by taking advantage of money-saving deals that allow you to get three bottles of pills for the price of two or five bottles for the cost of three.

If you are very overweight and anticipating a long weight loss journey, it makes good sense to choose the offers that provide the maximum savings.

Phentermine Over the Counter FAQs

Here are some of the most frequently asked questions and concerns about Phentermine diet pills.

Can you buy authentic Phentermine over the counter?

You cannot buy branded Phentermine, such as Adipex or a generic version over the counter unless you have a valid prescription. Phentermine is a controlled substance and an anorectic similar to an amphetamine which means that a licensed doctor will only prescribe if he or she feels your are in danger from weight related complications.

What does over the counter phentermine mean?

Over the counter means buying a non-prescription and non pharmaceutical product without a doctor's approval or knowledge from a pharmacy or drug store counter. So "over the counter Phentermine" usually means a natural alternative that works in a similar way but is not a drug class but naturally formulated.

Is it possible to buy legitimate and real Phentermine online?

Some online pharmacies offer this service but only to customers who provide valid prescriptions from registered licensed physicians or doctors.

How safe is Phentermine?

Phentermine is generally considered safe when used as prescribed under the guidance of a healthcare professional. However, it may cause side effects such as increased heart rate, high blood pressure, and insomnia. It is important to follow the dosage guidelines and discuss any concerns you may have with your doctor.

How do natural alternatives differ from phentermine?

Unlike phentermine, natural alternatives do not require a prescription. They are made from natural ingredients and tend to have milder effects. Phentermine works by suppressing appetite and increasing energy levels.

Natural alternatives generally do these things too and also provide a range of additional weight loss benefits that help your body burn fat more efficiently.

Can natural appetite suppressants be used as a long-term solution for weight loss?

Unlike Phentermine diet pills, there is no limit as to how long you can continue using natural alternatives. They provide ongoing weight loss support, helping you to burn stored fat until you reach your weight loss goal.

Do Phentermine alternative supplements interact with medications?

Natural alternatives may have potential interactions with certain medications. It is crucial to inform your healthcare provider about any supplements you are taking, as they can advise you about potential interactions and may be able to modify your treatment if necessary.

Can I take natural diet pills if I have a medical condition?

If you have an underlying medical condition, it is important to seek professional medical advice before taking natural appetite suppressants or any other type of supplement. Some ingredients may interact with certain conditions or medications. Your doctor will be able to provide appropriate guidance.

Can Phentermine diet pills or natural alternatives help with emotional eating?

Phentermine and some natural alternatives may help reduce cravings and control appetite, which can be beneficial for managing emotional eating.

However, it is important to address the underlying emotional triggers and develop healthier coping mechanisms. It's best to focus on the core problem instead of only managing its symptom.

Is it safe to use natural weight loss pills during pregnancy?

Although it may be safe to do so, it's unwise to use dietary supplements or weight loss supplements while pregnant without obtaining prior medical approval.
