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 with my clients, 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.
Our Top Products (September 2023)
1 - PhenQ (Editor's Choice)
We reviewed PhenQ and found it to be the number one among our natural phentermine alternatives because I’ve consistently had the best results with my clients who integrated this product into their weight-loss regimen.
It has a clinically tested fat-burning formula with piperine and alpha-lacy reset, which 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].
Piperine, one of the main components of pepper, has been shown to have diverse biological activities, including anti-inflammatory, antioxidant, anti-atherosclerotic anti-obesity effects and blood lipid improvement in a variety of cell types and animal models.
- Jisu Kim, Physical Activity & Performance Institute
A proprietary complex called alpha-lacy reset contains alpha-lipoic acid, cysteine, and magnesium, which are combined to neutralize free radicals and help the body increase metabolism and, consequently, fat burning [3].
It also contains good amounts of caffeine and other stimulants, but none of them have given my clients any jitters or sleep problems so far.
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 is a very effective weight loss pill that claims to help elevate mood and improve mental focus. Users have reported increased energy to take on more tasks throughout the day and stay motivated.
The blend of vitamins fights hunger pangs and cravings, hence helping you shed weight more efficiently.
It contains Rhodiola Rosea and L-tyrosine, which were studied for their ability to improve focus and concentration, which should ultimately make the workouts easier to complete [4].
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 [5].

3 - Phen24
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.
These two sets of OTC diet pills have different fat-burning ingredients, which are combined to facilitate healthy weight loss over 24 hours.
Phen24 Day formula contains minerals such as zinc, manganese, and copper, primarily included to boost metabolism and increase muscle growth [6]. It also contains Guarana extract, which has been shown to increase metabolic rate by 3-11% over 12 hour period [7].
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 [8].
Although it is among very good natural OTC phentermine alternatives, in addition to significant weight loss, most of my clients primarily report eliminating insomnia and snoring problems, making them sleep better.
This pill has helped improve their sleeping patterns, and they no longer struggle with insomnia-related fatigue.

- Copper : 1mg
- Iodine : 150 mcg

4 - Leanbean
LeanBean is an all-natural, vegan-friendly fat burner specifically designed to promote healthy weight loss in women.
This particular one can enable users to lose weight quickly, primarily by increasing fat metabolism.
My dietician informed me that by combining that with its ability to keep you fuller for hours, you are likely to notice significant weight loss within a short period.
According to testimonials on its official site, Leanbean improves digestion from a few days into its usage.
Leanbean also claims to help regulate blood sugar and blood pressure levels.
Most of my female clients I recommend this product were able to lose weight more quickly and they routinely experience increased energy and reduced fatigue.

Primeshred weight loss pills also contain ingredients included to trigger thermogenesis, which causes the system to burn calories to increase body temperature [9].
It contains ingredients such as L-tyrosine, DMAE, and Rhodiola Rosea, which should be able to strengthen mind-muscle connection and alertness during the day [10].
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 [11].
Primeshred helped a few of my clients who managed to lose a noticeable amount of fat within two months, ranging from 8 to 15 pounds compared to the initial body weight.
In terms of fat loss, Primeshred scores an 8 out of 10 based on average weight loss among my clients.

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.

What Factors to Consider When Buying Natural Phentermine Alternatives?
Factors to consider when buying Natural Phentermine Alternatives are ingredients 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 [14].
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.
Manufacturer's Reputation
While there are emerging scam manufacturers, others have upheld a reputation for manufacturing effective supplements for years.
A good phentermine alternative is more likely 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
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 the account things like brand reputation, ingredients sourcing, and if the products have any additives and 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.
