5 Best Over The Counter Alternatives To Phentermine!

the 5 best over the counter alternatives to Phentermine and Adipex

Here is everything you need to help you choose the best over the counter Phentermine diet pills for quick weight loss results.

There is no doubt that prescription diet pills like Phentermine and Adipex are the strongest options available when it comes to the best solutions that can help you lose weight fast.

But the reality is there are way too many challenges you are going to face when it finally comes down to actually getting your hands on real Phentermine diet pills.

First off you need to be classified as clinically obese with serious health challenges in order to get a prescription from your doctor.

And if you are someone who can’t get a prescription, buying Phentermine online comes along with way too many risks, both legally and to your health.

This is why most people nowadays are choosing an over the counter alternative to Phentermine instead.

In this guide, I am going to give you 3 of my personal top picks for the best alternatives to Phentermine that you can buy over the conter without a prescription.

Do OTC Alternatives Really Work?

Prescription Phentermine HCL works via two different pathways to help you lose weight:

  1. Appetite suppression for overall caloric control
  2. Increasing your metabolic rate to facilitate greater fat burning

The formulations that top manufacturers of over the counter alternatives are using in their products today enable you to get similar benefits without the high price tag and without all of the risks involved.

Avoiding the negative side effects is what seals the deal for most people to go ahead with an otc product.

So let’s take a look at the top weight loss pills on the market today…

Top 3 OTC Phentermine Alternatives

The best alternatives to Phentermine that I have found to date are Phentramin-D, PhenQ and FenFast 375.

These carefully selected diet pills have been determined to be the most effective by their relation to reproducing the effectiveness of the original prescription.

Although a non-prescription supplement is not going to be as effective as a classified drug will, the products that are showcased here are the closest thing to Phentermine you are going to get in an over the counter supplement.

1. Phentramin-D

Over The Counter Phentermine

What Is Phentramin-D?

Phentramin-D is a groundbreaking nutraceutical product that is hands down the absolute best over the counter Phentermine alternative on the market today.

It has been precision formulated by Lazarus Labs with 100% synthetic ingredients that target fat loss in similar pathways to the original prescription.

The truth is, this is as close as you are going to get to the “real deal” from a legal over the counter supplement.

What Makes It So Effective?

Phentramin-D is different because unlike just about every other diet pill on the market today, it is not an herbal product, but a powerful nutraceutical compound.

What that means is you get the weight loss support to wipe out uncontrollable hunger while at the same time giving your metabolism the boost it needs from 100% synthetic pharmaceutical-grade ingredients.

And everybody knows with the right tools, you can easily overcome your weight-stall and finally see the numbers drop on the scale.

You can trust that you are getting the absolute highest quality over the counter supplement on the market, because Lazarus Labs is the industry leader when it comes to producing completely safe and effective non-prescription solutions.

2. PhenQ

Phentermine Alternative Over The Counter

What Is PhenQ?

PhenQ, otherwise known as In-Phentermine-Q, is currently the second leading Phentermine substitute that you can buy over the counter.

Unlike Phentramin-D though, PhenQ is comprised of 100% herbal ingredients and boasts tackling weight loss from a total of five different pathways.

What that gives you is one of the most complete all-natural fat loss formulas that doesn’t require a prescription.

What Makes It So Effective?

What makes PhenQ superior to other over the counter alternatives to Phentermine?

Well to start out with, because this is an herbal product you may find similar ingredients in other fat loss supplements.

But it’s the proprietary blend of these ingredients, and the quality of ingredients, that creates a powerful synergistic effect and ultimately makes the difference.

PhenQ is manufactured by BAUER Group using the highest standards in quality pharmaceutical preparations, both in the US and UK, in FDA and GMP approved facilities.

In addition, PhenQ contains a “secret ingredient” called a-Lacys Reset®, which has been shown in clinical studies to decrease both body weight and body fat levels – and has even been shown to increase muscle mass too!

PhenQ Ingredients:

  • Calcium Carbonate
  • Caffeine Anhydrous
  • L-Carnitine Furmarate
  • Nopal
  • Magnesium Stearate
  • Capsicum Extract
  • Sipernat 225
  • Niacin Powder
  • Piperine Extract
  • Chromium Picolinate

PhenQ Main Advantages:

  • Accelerate your metabolism and increase thermogenesis for an increase in metabolic rate and even greater fat loss
  • Curb your appetite for complete calorie control and the ability to stick to a structured weight loss program
  • Boost your energy levels and overall mood throughout the day for better performance whether you are at the office or the gym


If you prefer an all-natural Phentermine substitute over a product that contains synthetic ingredients, and need the weight loss support of several different diet pills, then PhenQ is the right choice for you.

The addition of a-Lacys Reset® in the formula to further accelerate your metabolism and shift your body to burn more fat quickly is a total game changer.

3. Phen24

The best non prescription phentermine alternative

What Is Phen24?

Phen24 is the only over the counter Phentermine alternative that combines both a daytime and nighttime formula for 24/7 fat loss.

This is one of the rare fat loss solutions on the market that has been able to successfully implement a combination of a separate AM and PM fat loss formula.

What Makes It So Effective?

The key to Phen24’s effectiveness is its ability to keep your metabolism cranked throughout the evening, while at the same time quelling your hunger and helping you to get a good night’s sleep.

Most other supplements only give you a metabolic advantage during the first half of the day.

And because most products contain stimulants, taking a supplement too late is going to wreak havok on your sleep.

Phen24 gives you one of the most complete fat loss systems available, providing metabolism boosting benefits around the clock.

Phen24 Day Ingredients

  • Caffeine
  • Guarana Extract
  • Cayenne Powder
  • Phenylalanine
  • Iodine
  • Manganese
  • Zinc Citrate
  • Copper Sulphate

Phen24 Night Ingredients

  • Glucomannan
  • Chromium Picolinate
  • Biotin
  • Choline Bitartrate
  • Molybdenum (Sodium Molybdate)
  • Pantothenic Acid (Vitamin B5)
  • Thiamine (Vitamin B1)
  • Pyridoxine HCl (Vitamin B6)
  • Green Tea Extract
  • Ascorbic Acid (Vitamin C)
  • Griffonia Extract
  • Hops Extract

Phen24 Day Main Advantages

  • Helps to boost your metabolism to enhance calorie burn and weight loss
  • Boosts energy levels to fuel daily exercise, further boosting your metabolic rate
  • Burns more calories, helping to make shedding weight a seamless process

Phen24 Night Main Advantages

4. FenFast 375

Top Over The Counter Adipex Alternative Diet Pills

What Is FenFast 375?

FenFast 375 is the best selling product from Intechra Health and similar to Phentramin-D, it is comprised of 100% synthetic ingredients for superior fat loss.

This pill was also specifically formulated to give dieters a healthier over the counter option to prescriptions like Phentermine and Adipex.

The main difference is that it is missing a couple of key ingredients, giving Phentramin-D a serious advantage and clearly leaving it the superior of the two.

The difference in formulation also reflects on the price of this diet pill, making it a more affordable alternative for anyone who is on a budget.

What Makes It So Effective?

FenFast 375 does have its own advantages though, specifically, a unique blend of scientifically-researched ingredients that includes the amino acid L-Theanine.

The problem with a lot of fat burners on the market that contain stimulants to boost metabolism is the “jittery” feeling that they can often cause.

L-Theanine has the ability to counteract any over-stimulation that may occur when combined with stimulants such as caffeine, providing you with a smooth and steady release of energy.

So you get all of the energizing effects without any of the jitters.

FenFast 375 Ingredients:

  • Beta Phenylethylamine HCl (PEA)
  • 1,3,7 Trimethylxanthine
  • Hordenine HCl
  • L-Theanine

FenFast 375 Main Advantages:

  • Provides hunger crushing appetite suppression for total control over your cravings and therefore control over your daily calorie intake
  • Contains scientifically-researched thermogenic ingredients for a boost in metabolism and an increase in fat burning effects
  • Not only provides metabolic enhancement, but also an immediate energizing effect along with improved concentration, focus and mood support


If you prefer a synthetic fat loss formula but cannot afford the higher price tag of a superior product like Phentramin-D, this is the optimal choice for you.

Don’t let the low-price deter you though; this is still one of the top substitutes for Phentermine and has a long list of happy customers who have successfully lost weight with it.

5. PhenBlue

PhenBlue legal Phentermine alternative diet pills

What Is PhenBlue?

PhenBlue is another one of Intechra Health’s top over the counter alternatives to Phentermine and other prescription diet pills.

But unlike FenFast 375, this is an all-natural formula that contains science-based clinically researched ingredients.

PhenBlue is unique in this class of supplements though, because it is the only product that contains a fat binder inaddition to thermogenics and metabolism boosters.

What Makes It So Effective?

PhenBlue shows its strength by providing a 360 degree approach to fat loss and achieving overall health.

The main difference between this product and others in this category is the addition of NeOpuntia®, which has been shown in clinical studies to diminish fat absorption from dietary fat that you eat.

This gives you all the benefits of a fat burner with the addition of a fat binder for enhanced fat reduction.

Add to that all of the energy and focus enhancing benefits and you’ll see why this has become such a popular safe alternative to prescriptions.

PhenBlue Ingredients

  • NeOpuntia® (Prickly Pear)
  • Caffeine Anhydrous (150mg)
  • Organic Green Tea (Matcha)
  • Theobromine

PhenBlue Main Advantages

  • Contains NeOpuntia® to help reduce overall calorie consumption by binding with fats from food
  • Helps to enhance energy, focus and concentration to help you get the most out of every day
  • Helps to boost thermogenesis to optimize metabolic rate and create the best fat burning potential


If you’re looking for a budget-priced alternative to weight loss prescriptions and prefer an all-natural formula that contains a fat binder, this is a great choice for you. You’ll get all of the advantages of a thermogenic fat burner plus the added benefit of an agent to help reduce overall dietary fat intake.

The Benefits of Taking A Non-Prescription Phentermine Alternative

You may be thinking that there is no way that an over the counter weight loss supplement is going to produce the same results as prescription Phentermine diet pills.

Well, you are absolutely correct in your assumption, and that is actually a good thing when it comes to your health.

You see, although Phentermine and Adipex are extremely powerful and can help you to lose a lot of fat in a short amount of time, they are also extremely dangerous and come with a whole host of negative side effects.

That’s the reason why they are limited only for short term use and only for those with a serious health risk when prescribed by your doctor.

And if any of the Phentermine alternatives that are listed above could product the exact same level of results then guess what: they would come with the exact same side effects and put your health at risk.

And that is exactly the main advantage that they give you: fast and effective weight loss without all of the risk that is involved with taking a prescription medication.

And you can take them for longer periods of time before cycling off, which gives you the benefit of a longer and steadier weight loss which will all add up over time.

So keep all of this in mind if you are still on the fence about buying an over the counter Phentermine and Adipex alternative.
