Phentermine diet pills are prescription weight-loss medication, which makes them inaccessible to people who can't get the prescription.

Luckily, there are plenty of over-the-counter phentermine alternatives, many of which I’ve used and tested myself or had my clients use, and in this article, I outlined those that consistently performed best over the years.

I’ve consulted with my dietitian and a few of my fitness colleagues, and I’ve compiled all of my past and present data here so you can see how phentermine alternatives stack up against this prescription weight-loss medication.

Let’s dive in.

Pros

  • Suppresses appetite with science-backed ingredients

Cons

  • PhenQ is only available for purchase through the official website.

PhenQ has a clinically tested fat-burning formula with piperine and alpha-lacy reset, which, according to a study in the National Library of Medicine, makes it quite effective at targeting fat reserves [1].

Piperine, which comes from black pepper extract, is known for aiding fat and carbohydrate metabolism, ultimately leading to better utilization of fuel and improving exercise output and fat loss [2].

My clients have consistently reported reduced cravings in between meals and a significantly increased rate of fat loss, which is why I always feel free and confident to recommend why I regard it as one of the best weight-loss supplements on the market.

PhenGold has Rhodiola Rosea and L-tyrosine, which according to a PubMed study, can improve focus and concentration, which should ultimately make the workouts easier to complete [3].

It also has green coffee beans, which contain natural antioxidants in the form of polyphenol compounds, which should be able to aid in recovery after strenuous workouts [4].

Most of my clients have been able to stay off snacks and meals for close to 8 hours after using PhenGold, and they also reported being able to do more reps and sets at the gym.

Pros and Cons

Pros

  • Improves mental focus
  • Prevents food cravings at night
  • Reduces stress levels

Cons

  • The daytime capsule contains stimulants that may be addictive

Phen24 is another natural phentermine alternative, but it is a specific weight loss supplement because you get separate Phen24 pills for the day and a different set that you take for the night.

Phen24 Day formula contains minerals and Guarana extract, which has been shown to increase metabolic rate by 3-11% over 12 hour period [5].

The night formula also contains many fat-burning ingredients, such as Green tea extract and Glucomannan, which some studies show can make you feel fuller and help you lose weight [6].

It helped me with weight loss, eliminating insomnia and snoring problems. I no longer struggled with insomnia-related fatigue.

  • Results in dietary issues during the initial stages of usage

Primeshred weight loss pills contain ingredients such as L-tyrosine, DMAE, and Rhodiola Rosea, which should be able to strengthen mind-muscle connection and alertness during the day [7].

With these benefits, you should be able to stay driven and produce more intense strength output to get the most out of your exercise routine [8].

Primeshred helped me lose a noticeable amount of fat within two months - up to 15 pounds compared to the initial body weight.

It also contains some thermogenic ingredients such as White Willow and caffeine anhydrous [10].

After using it for a few weeks, some of my clients noticed reduced appetite, which helped them limit their calorie intake. One of them lost about 10 lbs in two months which is a considerable reduction in fat as he managed to preserve all of his muscle mass.

As an alternative, Capsiplex Trim is recommended. This supplement, tailored for women, focuses on fat shredding, metabolism boosting, craving reduction, training effectiveness, and enhanced focus.

How We Tested Best Over the Counter Phentermine Alternatives

Here's how we chose the best over-the-counter Phentermine alternatives.

Effectiveness

We conducted a side-by-side comparison of the products, evaluating their effectiveness in curbing appetite, boosting metabolism, and promoting weight loss. The comparative analysis allowed us to identify standout products that consistently delivered results.

Ingredient Evaluation

We scrutinized the ingredients used in these supplements, analyzing their scientific basis and potential impact on weight loss. Our evaluation included a review of scientific research and clinical studies supporting these ingredients.

Price Comparison

We assessed the cost-effectiveness of each product, taking into consideration the price per serving and the duration for which a single purchase would last. This price comparison allowed us to identify products that offer value for money.

Feedback Collection

Throughout the testing process, we continuously collected feedback from our team members who were using the products. This ongoing dialogue provided valuable insights into any changes in appetite, energy levels, and overall well-being.

Long-Term Observations

To assess the sustainability of weight loss results, we extended our testing period beyond the initial weeks. This allowed us to evaluate the long-term impact of these supplements and whether users could maintain their weight loss.

Consultation with Experts

Periodic consultations with healthcare experts were conducted to ensure that our assessments were in line with the latest health and safety guidelines. These consultations helped us refine our recommendations and safety precautions.

Buyer's Guide

Factors to consider when buying natural phentermine alternatives are ingredient quality, manufacturer's reputation, and price.

Ingredients Quality

You need to be mindful of the quality of the weight-loss ingredients that you put in your body at all times.

My advice is to opt for vegan-friendly supplements with 100% natural ingredients since they give the best results with little to no side effects, especially for people with conditions like high blood pressure.

Most Phentermine alternates contain high doses of caffeine and stimulants, so check the amount if you are sensitive, as it may cause jitters [11].

Also, stay away from proprietary blends because transparency about the ingredients is the top priority when determining if the supplement is a good fit or not.

Natural vs. Synthetic Ingredients

Supplements featuring natural ingredients often leverage the power of plants, herbs, and other organic sources to aid in weight loss. These ingredients can be appealing to individuals seeking a more holistic approach to their health.

Natural alternatives typically have a lower risk of adverse side effects and may offer additional health benefits beyond weight loss.

For example, products containing natural appetite suppressants like glucomannan, green tea extract, or cayenne pepper can provide effective weight management without the potential drawbacks associated with synthetic ingredients.

While synthetic alternatives can be effective in reducing appetite and boosting metabolism, they may carry a higher risk of side effects.

Manufacturer's Reputation

A good phentermine alternative is more likely to be produced by a long-standing brand that transparently shares all information about its products.

If some OTC diet pills have no customer reviews or if they just hit the market with some “too good to be true” claims, I’d highly advise you to avoid them.

Value for Money

Supplement pills on money

To determine the value for money, compare the price of the product to the amounts of the weight loss ingredients.

You should also calculate the price per serving and then see how many servings you get in one packaging.

That should give you a ballpark of what you need to spend on the supplement monthly, which is the actual value of the product.

In general, diet pills that are more expensive tend to contain more potent ingredients, but this is not always the case.

You should also take into account things like brand reputation, ingredient sourcing, and whether the products have any additives or fillers.

Brands that offer money-back guarantees essentially give you one layer of security if you end up not loving the product, so that’s another small factor to consider.

Third-Party Testing

It's important to opt for products that have undergone third-party testing.

This means that a third-party testing lab has analyzed the ingredients, manufacturing, and production of the product. This should be an assurance that the product is safe and of standard quality.

Through third-party testing, you protect yourself from consuming banned weight loss ingredients, and it confirms that a supplement is free of contaminants like heavy metals and bacteria.

When choosing a supplement, make sure to check for a third-party certification stamp on the labels.

Where Can I Get Phentermine Alternatives To Lose Weight?

You can get Phentermine alternatives to lose weight from natural supplement companies.

Rather than basing the ingredients on controlled medical ingredients, these companies have focused on achieving similar results to promote weight loss with completely natural herbs, minerals, and amino acids.

The main aim of these products is to naturally boost your metabolic rate and suppress appetite cravings that would otherwise lead to snacking.

And the best thing is that you don’t need any kind of prescription from your doctor to start taking these supplements.

FAQs

Are Phentermine Over-The-Counter Substitutes Scams?

No, Phentermine over-the-counter substitutes aren't scams when purchased from reputable manufacturers like the ones we listed above and are able to provide legitimate results. However, the market crops up with scams every day, which is why it's advisable to do thorough background research beforehand and check customer reviews as we've done above.

Who Can Take Phentermine Over-The-Counter Alternatives?

Any adult keen on losing weight fast can take phentermine alternatives. People with cardiovascular diseases and pregnant or nursing women shouldn’t use these top phentermine alternatives.

What Is the Closest Alternative to Phentermine?

The closest over-the-counter alternative to Phentermine is PhenQ. It works by mimicking all the benefits you can get from the real phentermine but with no side effects.

Are Phentermine Over-The-Counter Alternatives Addictive?

No, Phentermine over-the-counter alternatives are not addictive because the ingredients used to make these products are natural and don't contain addictive substances. Even caffeine present in these products is included in low enough doses to not cause dependence in most people.

Our Verdict on the Best Over the Counter Phentermine Alternative

During the time we tested various over-the-counter phentermine alternatives, one product consistently stood out, and that was PhenQ. My clients have experienced remarkable results with it, and I can personally vouch for its effectiveness.

PhenQ offers a well-balanced blend of science-backed ingredients designed to curb food cravings and boost thermogenesis, ultimately leading to efficient and sustainable weight loss. It not only supports your weight-loss journey but also enhances your mood and energy levels.

While all six OTC phentermine alternatives are safe options, PhenQ has proven time and again to be a reliable choice.
