Now that we have discussed the best phentermine alternatives on the market, we will be discussing the ranking factors that help us decide on the top phentermine alternatives from the market.
Why Should You Use Natural Phentermine Alternatives Over Prescription?
Many who are looking for a weight-loss solution that is both safe and effective often turn to Phentermine. Millions of people have used Phentermine worldwide to help them lose weight quickly. Still, it also has some severe side effects that can be dangerous, especially if taken over an extended period. That's why many people have started using natural phentermine alternatives, with minimal side effects and no prescription required.
Safe & Effective
Natural phentermine alternatives are great because they provide a safe and effective solution for those struggling to lose weight. These supplements do not have the same harsh side effects as prescription Phentermine, making them more suitable for long-term use.
Sustainable Weight Loss
Natural phentermine alternatives are also effective for promoting sustainable weight loss. Take Garcinia Cambogia extract as an example; it helps block fat storage in the body while at the same time suppressing appetite so that you can finally reach your ideal body composition without having to starve yourself to achieve results.
Increase Metabolism & Energy Levels
Many natural phentermine alternatives also help increase metabolism and energy levels so you can burn more calories throughout the day and get better results from exercising or dieting. This increased metabolism can also help boost overall health, leading to increased well-being and greater chances of success when trying to lose weight naturally.
Another great reason natural phentermine alternatives should be chosen over prescription drugs is their affordability compared to prescription drugs – which may put a hefty dent in your pocketbook without guaranteeing results!
Natural supplements are much more budget-friendly than taking multiple expensive prescriptions per month, enduring any costly operations or plastic surgery treatments associated with losing weight fast, or simply not being happy with one's looks as far as physical shape/appearance goes.
The Factors Considered Before Choosing The Best Phentermine Alternatives
Below we have discussed in detail the factors our research and editorial team considered before choosing the best phentermine alternatives from the market.
The one thing we were the most skeptical about was the company of the over-the-counter phentermine supplement. Therefore, we chose only those weight loss supplements on the market whose company was reputed and known in the market for its products.
We did not want to share information about companies and their OTC phentermine alternatives that were a scam.
For this list of the best phentermine alternatives, only those weight loss supplement companies are chosen whose advertisement is honest and transparent. The ad must be realistic and not flashy.
The OTC Phentermine alternative companies that show that you could burn fat and lose weight after taking weight loss pills for just a few days or intend to treat, cure, or prevent any health issue related to weight gain are not at all preferred.
We need to know the ingredients used to make the best phentermine alternatives. We look for weight loss supplements that use high-quality, highly potent, and natural ingredients.
It is a preferred advantage if the chosen weight loss supplement uses scientifically tested and proven natural ingredients for healthy weight loss, like green tea extract, amino acids, natural appetite suppressants, etc.
The characteristics of the phentermine substitutes are one of the top factors we look forward to before curating this list of the best phentermine alternatives. These characteristics only decide the formulation and how Phentermine works on the human body.
The phentermine over-the-counter diet pills that are naturally made and use an additive-free formulation are preferred over many phentermine diet pills that use artificial ingredients and stimulants.
Only those phentermine alternatives were permitted entry into this list with an adequate dosage of natural ingredients in their formula. If the dosage of components is significantly less or more to provide health benefits to the human body, then that phentermine alternative is removed from the list immediately.
In this list, we have chosen those natural phentermine alternatives that provide a healthy dosage of natural ingredients, so the supplement is effective when consumed.
Several customer reviews and testimonials have mentioned that taking the 100% naturally-made formula of any weight loss supplement from this list has provided no significant adverse side effects or allergic reactions to their health. Thus, considered safe for consumption by individuals.
Pricing is one such factor that is most looked upon by the users of weight loss supplements. The users prefer Phentermine over-the-counter supplements available at an affordable rate. Still, we do not prioritize pricing the over-the-counter phentermine alternative.
We choose top Phentermine alternatives whose features and formulation are at par with others, which are affordable but with a not-so-effective formula.
Users prefer phentermine alternatives by companies that offer a secure 100% satisfaction money-back guarantee on their purchases. Therefore, in this list, we have mentioned only those dietary supplements by companies that accept returns and provide refunds in case the user is unsatisfied with the product.
The reviews and testimonials by users provide us with clear insight into the formulation of the phentermine over-the-counter diet pills, as these reviews by users mentioned online are unedited and unfiltered. Therefore, we look at many reviews regarding choosing the best phentermine alternatives from the market.
The Scientific Evidence-Backing Ingredients In Phentermine Alternatives
In this section, we'll look at scientific evidence backing up some of the ingredients found in popular Phentermine alternatives so you can make an informed decision.
We will discuss how these ingredients help boost metabolism and suppress appetite so you can lose excess body fat safely and effectively.
Green Tea Extract
Green tea extract (GTE) is an abbreviation of the scientific term ‘Camellia Sinensis Extract.' It's derived from Camellia Sinensis leaves and typically includes high concentrations of catechins – powerful antioxidants that are thought to offer numerous health benefits. Catechins are mainly concentrated in green tea because they comprise most of its active ingredients.
The presence of catechins in green tea has been linked with improved metabolism – which can lead to increased fat-burning potential and ultimately result in weight loss or maintenance. The antioxidant properties have also been attributed to reducing inflammation levels – as low-level inflammation has been linked to an increased risk for obesity.
Moreover, studies suggest that green tea can reduce body fat by directly blocking its accumulation through anti-obesity mechanisms such as reduced glucose absorption or decreased triglyceride levels.
Several studies have tested the effects of green tea extract on weight loss. For instance, one study published in 2015 involving 60 participants revealed that those who consumed a capsule containing both caffeine and GTE had a nearly 500% greater reduction in body mass than those who drank only caffeine without GTE after ten weeks.
Garcinia cambogia is a small tropical fruit native to South Asia that resembles a pumpkin. Its rind contains hydroxycitric acid (HCA), which has been found to have numerous beneficial effects on health. HCA is responsible for most of the health benefits associated with garcinia cambogia.
Based on research conducted by scientists worldwide, it appears there are several potential mechanisms involved in garcinia cambogia's ability to promote weight loss:
Extracts from garcinia cambogia can reduce ghrelin levels, a hormone associated with hunger and food craving. This helps suppress the appetite and makes people feel fuller for longer after eating.
Blocks Fat Production
The hydroxycitric acid present in the rind of garcinia cambogia may block the action of an enzyme called citrate lyase, which plays a vital role in lipid (fat) synthesis within cells. In other words, HCA blocks your body's ability to create fat from carbohydrates consumed during meals.
Several studies indicate that garcinia cambogia may effectively promote long-term weight loss in specific populations. One study published in the journal “Complementary Therapies in Medicine” showed that overweight adults who took G.cambogia–containing supplements lost significantly more weight than those who took placebo pills.
The cayenne pepper is a red-hot chili pepper of the capsicum family and is also often called ‘chili pepper.' It originated in South and Central America but can now be found worldwide as part of various cuisines.
There are many potential benefits associated with taking cayenne pepper in aiding with weight loss; it is believed that the heat from the spice helps boost metabolism by raising your body's core temperature slightly for a short period after consumption, leading to a more significant calorie burn than would typically occur during restful periods.
A study conducted in 2016 found that subjects who consumed capsules containing 3 mg of cayenne per day experienced reduced appetite levels demonstrating that this spice might have tangible effects on fat deposits in the body when included as part of an overall healthy diet plan over extended periods (six months).
Vitamin B6, also known as pyridoxine, is part of the family of compounds known as the vitamin B complex. This group of nutrients helps support a healthy nervous system and cognitive function. It is also a cofactor in many metabolic processes, including energy production, protein metabolism, and immune system support.
Research has found that Vitamin B6 can be essential in maintaining a healthy body weight. Studies have correlated higher dietary intake with lower body fat percentages in overweight children and more nutritional lipid profiles in obese adults.
Additionally, taking Vitamin B6 supplements facilitates satiety during mealtime and potentially decreases caloric consumption.
Glucomannan (gummi-gutta) is considered an indigestible dietary fiber because it doesn't get absorbed into the bloodstream like other forms of fiber and passes through the body instead. As with all nutritional fibers, glucomannan helps promote digestion and increase fullness after meals.
The leading theory behind using glucomannan to help with weight loss is that it may help reduce appetite by making people feel fuller faster, so they end up eating less than they would without taking glucomannan.
That being said, some studies have indicated that glucomannan may also be effective at helping reduce cholesterol levels and blood sugar levels as well.
This can be beneficial if you are trying to lose weight and have existing health conditions.
A study published in Scientific Reports found that taking a combination of two supplements (one containing 4 grams of glucomannan) significantly decreased hunger levels among test subjects who were overweight or obese after two weeks compared with those who just took a placebo supplement (Krattai et al., 2015).
The stimulant effect of guarana has been shown to increase metabolism, reduce appetite and decrease fat absorption in animal studies. A few human studies have been conducted on how guarana can help with weight loss because it affects metabolic rates and energy production.
In one randomized, double-blind clinical trial comparing the effects of green tea extract (containing both caffeine and epigallocatechin gallate or EGCG) to guarana (containing just caffeine), researchers found significant reductions in body fat mass with both treatments.
The authors suggested this because guarana could boost metabolic activity while reducing food intake due to its appetite-suppressing effects.
Hops contain compounds such as humulone and lupulin that have anti-inflammatory properties and may help reduce body fat. Some studies suggest that hops can improve overall metabolic health by reducing fasting glucose and insulin levels. In addition, hops are a valuable source of dietary fiber that helps reduce appetite and makes it easier for your body to absorb food and other nutrients more efficiently.
In a double-blinded study published in The Journal of International Medical Research, participants were given 250 mg of dry extract of hops per day for 12 weeks alongside their regular diet.
At the end of the study period, researchers observed that the average waist circumference was decreased by 3 cm compared to baseline measurements. In contrast, total body fat had significantly reduced by 8% compared to baseline measurements.
Griffonia simplicifolia is a small shrub reaching up to twelve feet (3.6 meters) in height. The plant has green leaves with white flowers that bloom from April through June and typically produce brown fruits in August and September. Leaves, roots, and seeds are used in traditional African medicine for their alleged healing properties.
Though it's become popular among some people looking to lose weight, there have been few scientific studies on the ability of Griffonia simplicifolia extract containing 5-HTP or tryptophan to help people lose weight or otherwise improve physical health outcomes positively related to obesity or excess body weight.
In one randomized, double-blind, placebo-controlled clinical trial conducted on 30 adult men between 18 and 50, participants ingested 500 mg of dry Griffonia berries daily for eight weeks.
After the study, researchers noted that none of the participants experienced any significant changes in body weight during the experiment.
Caffeine is believed to increase your metabolic rate, allowing the body to burn more calories throughout the day. Studies show that taking large amounts of caffeine in supplement form can increase your metabolic rate by 3 – 11%.
Caffeine may be able to suppress your appetite, leading to eating less and ultimately resulting in weight loss. One study showed that participants who took high doses of caffeine decreased their calorie intake by 8% compared to those who didn't take any caffeine.
When we feel tired or sluggish, it can lead to poor food choices or skipping workouts. Caffeine can help boost vigor so you have the motivation to get up and move your body. When taken before exercise, research shows that caffeine may enhance performance and burn fat while aiding weight loss.
Green Coffee Bean Extract
The primary active component in GCBE is chlorogenic acid, an antioxidant-rich molecule in much higher concentrations within green coffee beans than in regular brown ones.
In addition to being high in antioxidants and other beneficial plant compounds, chlorogenic acid has been credited with helping slow down glucose absorption following meals, which keeps your blood sugar levels stable and boosts your metabolism over time.
In 2012, a study was published in the journal Diabetes Metabolic Syndrome and Obesity revealing a powerful metabolic effect when participants took green coffee bean extract for eight weeks.
At the end of this period, those taking green coffee bean extract had lost an average of 17 percent of their body fat compared to those taking the placebo, which only saw a 3 percent decrease in body fat percentage.
FAQs About Phentermine and Supplementation
Q: What Is Phentermine?
A: Phentermine hydrochloride (HCL) is an anorectic medication used for weight loss and as an adjunct to lifestyle modification that helps reduce body weight without compromising safety or efficacy. It works by stimulating the release of norepinephrine and dopamine in the brain, which creates feelings of satiety (fullness).
Because of its appetite suppression effect, Phentermine has been prescribed for obese patients since 1959. The US Food and Drug Administration (FDA) approved Phentermine as an over-the-counter supplement in 2012.
Q: How Long Does Phentermine Last In My System?
A: The length of time that Phentermine stays in your system depends on several factors, including age, gender, health status, diet, and other medications you are currently taking.
Q: Is Phentermine A Controlled Substance?
A: There are no federal restrictions on prescribing or possessing Phentermine except in certain jurisdictions where it may be classified as a controlled substance due to potential abuse. While this is true for most states in the United States, Canada also ranks Phentermine under its Controlled Drugs and Substances Act (CDSA). Europe's European Council also lists it as a doping agent banned from professional sports competitions.
Q: Can Phentermine Cause Side Effects?
A: Many people experience mild side effects when taking Phentermine. These symptoms usually go away after a couple of weeks. If you experience any side effects, talk to your doctor about what you can do to minimize them.
Q: What Is Phentermine Used For?
A: Phentermine is used as a prescription medication to treat obesity. This drug works by stimulating the brain's appetite center so that you feel less hungry. When you eat less food, you naturally burn off more calories.
Q: Who Should Not Take Phentermine?
A: People who are sensitive to caffeine should avoid this product. Also, those who suffer from heart disease, high blood pressure, diabetes, thyroid disorders, glaucoma, urinary tract infections, or mental illness should not take Phentermine.
Q: Why Is Phentermine A Schedule IV Controlled Substance?
A: Phentermine is classified as a Schedule IV controlled substance because it has the potential for abuse and addiction when used in high doses for extended periods. As such, there are strict regulations on how it can be prescribed and dispensed.
To obtain Phentermine legally and safely, you must have a valid prescription from your doctor or healthcare provider.
Q: Can You Buy Phentermine Online?
A: It is illegal to purchase medication without a valid prescription including Phentermine. Some sellers offer fake or unregulated versions of the drug for sale on the internet, but these products often contain ingredients that can be dangerous or even deadly. It is never worth risking your health by buying from questionable sources.
Prescription versions of Phentermine can be bought from licensed pharmacies if you have a valid prescription from your doctor. Ensure you only purchase your medication from reputable, verified sources requiring appropriate dispensing documentation. Never buy anything from questionable websites or vendors who claim drugs are available over the counter or without a prescription.
Q: Is It Safe To Buy Phentermine Online?
A: Generally, it's not safe to buy any medication without a doctor's prescription because there may be severe health risks associated with taking drugs that are not medically authorized.
Additionally, many counterfeit versions of this drug are available on the market and don't necessarily contain what they say they do. Therefore, even if a site appears legitimate, there could still be bogus products sold from these sites.

For these reasons, it's vital that anyone who takes Phentermine follow their doctor's instructions carefully and not exceed recommended dosage amounts under any circumstances.
