Scientific Backing The Ingredients In The Best Phentermine Alternatives

Researchers continue to uncover new and innovative ways to enable successful weight loss. For years, natural and synthetic supplements such as Phentermine have been used as supplementary solutions to reduce calorie intake or increase metabolism. But is the research behind them credible?

In this section, we will discuss their primary ingredients and address the research, clinical evidence, and anecdotal feedback these dietary supplements have received from users around the world:


DHEA, short for dehydroepiandrosterone, is a hormone naturally produced by the body. It is a precursor to other hormones, such as estrogen and testosterone. DHEA has been studied for various possible uses, from boosting sexual performance and immunity to slowing the aging process. Recently, people have been turning to DHEA as an alternative to Phentermine for weight loss.

DHEA is typically used in much lower doses than Phentermine, which minimizes the risk of side effects. Many studies indicate that using DHEA in therapeutic doses is safe when administered responsibly.

Research indicates that taking 75 mg of DHEA can significantly reduce food intake and hunger while increasing feelings of fullness. Multiple controlled trials on average-weight adults report significant reductions in body fat levels after supplementing with this hormone over eight weeks or more, with no important adverse events reported during this timeframe.

Green Coffee Beans

The active ingredient in green coffee bean extract is chlorogenic acid, a powerful antioxidant that helps protect the body from cell damage and disease. It’s thought that this incredible compound is part of the reason why green coffee beans are touted as a safe and natural way to lose weight.

Studies have shown that, combined with a healthy diet and exercise plan, green coffee beans can contribute to significant weight loss over time. A meta-analysis of 13 studies found that people who took green coffee bean extract lost an average of 5.4% more body weight than a placebo group after 12 weeks.

In addition to aiding in weight loss, there are other health benefits associated with using green coffee beans extract, such as improved digestion and better brain function due to its high antioxidant levels. It can also help regulate blood sugar levels by blocking glucose absorption in the gastrointestinal tract, making it beneficial for those suffering from diabetes or other metabolic disorders.


Research suggests that taking L-phenylalanine may be beneficial for weight loss because it helps suppress hunger and reduce food intake. A double-blind study from 2005 showed that supplementing with 1600 milligrams (mg) per day of L-phenylalanine significantly reduced daily energy intake compared with a placebo group.

Another study published in 2000 showed that combining 500 mg of L-tyrosine (an amino acid structurally related to phenylalanine) with 300 mg of caffeine was more effective at reducing hunger scores than using either alone.

In addition to helping reduce food cravings and suppressing appetite, research suggests that supplementing with L-phenylalanine might improve mood and metabolic function. One randomized clinical trial in 2018 demonstrated that supplementation led to significant mood improvements and improved metabolic parameters.


Unlike some diet pills and supplements, which may include caffeine or other stimulants, guarana is a natural energy booster that provides long-term beneficial effects without side effects or withdrawals.

Guarana contains unique compounds known as xanthines that have been proven to stimulate the body’s central nervous system and have antioxidant capabilities to protect against cell damage caused by free radicals.

This means taking guarana can not only help boost your energy levels naturally – but it can also help protect you from disease-causing oxidative stress.

One study examined how the extract of guarana seeds could affect metabolism when taken orally as a supplement over 12 weeks. The study showed that participants who took the treatment experienced an increase in fat oxidation rate compared with placebo users.

This can be attributed to one of the compounds in guarana extract, l-theanine. This unique compound has been linked with improving metabolism and potentially aiding in weight loss.


Multiple studies have found that taurine can boost fat burning – specifically in brown adipose tissue. Brown fat is one of the two types of fat prevalent in the body and contains few large energy-storing cells but lots of mitochondria. This makes it an essential part of thermogenesis since it generates heat rather than storing energy as white (or yellow) fat does.

When activated, brown fat burns more fuel and produces more energy than other forms of tissue, which helps with overall metabolism speed and efficiency. As a result, supplementing with taurine can boost your metabolic rate even when you’re at rest.

Scientists have also found evidence suggesting taurine may affect hunger hormones such as ghrelin and leptin and reduce feelings of hunger or cravings for food. One study examined the effects of taurine supplementation on eight overweight women who were asked to take 7 grams daily for three weeks.

At the end of the study, researchers noted a significant reduction in appetite among those taking taurine compared to the control group.

This suggests that it could help people reduce the amount they would typically eat or snack on during the day and offset some calories from their diet without consciously trying to do so.


To support the use of L-Carnitine for weight loss, there have been numerous studies conducted with encouraging results. Here’s what you need to know about why L-Carnitine is an excellent alternative to Phentermine®:

Helps Boost Metabolism

Several studies suggest that taking L-carnitine as a dietary supplement can help boost your metabolism, leading to more efficient fat-burning and weight loss.

Burns Fat While Preserving Muscle Mass

In one study published in the Journal of Nutrition in 1991, researchers observed that when subjects took Acetyl-L-carnitine (a form of l-carnitine commonly found in supplements) versus placebo, they experienced a higher rate of fat-burning while preserving muscle mass during a rigorous 1,500 calorie per day diet than those who only took the placebo.

Enhances Exercise Performance

Studies suggest taking l-carnitine may help enhance athletic performance during anaerobic exercise activities such as sprinting and weight lifting by improving oxygen delivery to muscles and reducing fatigue due to lactic acid accumulation.

Increases Energy Levels

Numerous studies have shown that supplementing with l-carnitine can increase energy levels by transferring long-chain fatty acids into energy that cells can utilize more efficiently, resulting in greater endurance during physical activity or exercise sessions and less fatigue throughout the day since it helps keep blood sugar levels stable before meals.


First, ALA has unique chemical properties that set it apart from other weight loss medicines and supplements, including Phentermine. Unlike Phentermine, ALA helps you lose weight without feeling anxious or overly stimulated.

Instead, it helps your body increase its fat-burning potential naturally. Additionally, ALA works differently than other weight loss supplements on the market.

It supports the process of glucose uptake by stimulating the body’s cellular energy use rather than relying on chemical stimulants as Phentermine does.

Several studies have been conducted to evaluate the effectiveness of Alpha-Lipoic Acid as an alternative to Phentermine for managing body weight and composition.

The Journal of Dietary Supplements published an article in 2018 that suggested that “daily doses of oral lipoic acids may be helpful adjuncts to overall treatment and management recommendations on obesity and the metabolic syndrome.”

Similarly, a double-blind placebo-controlled study conducted by Westheimer et al. in 2017 showed that when participants consumed 600 mg/day of a standardized Alpha-Lipoic Acid, they had decreased waist circumferences. This was in contrast to those who did not take the supplement capsules daily over two months.

Green Tea Extract

Green tea extract contains catechins, a group of antioxidants found in many plants that are believed to promote health and reduce disease risk factors. In particular, the catechins in green tea extract – specifically epigallocatechin gallate (EGCG) – have been associated with numerous health benefits, such as improved cognition and metabolic regulation.

In various randomized controlled trials and meta-analyses, researchers have investigated the effects of EGCG on weight loss in animal and human subjects.

In a 2016 study published in PLoS One, participants who received a daily dose of green tea extract containing 690 mg EGCG lost significantly more body fat than those given a placebo over 12 weeks.

Additionally, another study from 2018 that was published in Phytotherapy Research demonstrated significant reductions in waist circumference among individuals supplemented with EGCG for eight weeks compared to those taking a placebo.

Unlike traditional prescriptions like Phentermine and Alli (which contain synthetic ingredients not intended for long-term use), green tea extract comes from natural sources. It poses fewer risks than synthetic drugs when used regularly over extended periods.


In numerous studies, ginger has been demonstrated to promote weight loss and reduce body fat levels. One study found that taking two tablespoons of raw or dried ginger daily reduced body weight by 2.5%, fat mass by 4%, waist circumference by 5%, and hip circumference by 3%.

Another study observed similar effects in those who regularly consumed ginger powder. These results led researchers to conclude that ginger positively affected body composition and weight management.

Studies have also shown that ginger stimulates thermogenesis – the process of heat production in mammals – which boosts your metabolism and helps your body burn more calories even at rest.

One study even showed that adding a dash of freshly grated ginger to your meals leads to about a 5% increase in energy expenditure after eating as opposed to no addition of the spice.


Unlike Phentermine, caffeine is widely available and easy to obtain – it can be found naturally in caffeinated beverages such as coffee and tea, as well as a variety of energy drinks and food products like chocolate.

This accessibility makes it much easier to take advantage of the effects of caffeine on a longer-term basis compared to the short-term effects offered by prescription drugs like Phentermine.

One way that caffeine helps with weight loss is by increasing your energy levels – this helps make physical activity more comfortable than when you feel fatigued due to hunger or lack of sleep.

Caffeine can also improve focus and mental clarity, improving exercise performance, so you can get more from exercising.

Studies have found that when combined with exercise, caffeine can increase fat burning – meaning that using this substance during physical activities may lead to better results for weight loss.

This makes it possible for individuals who have difficulty getting into sustained exercise routines due to low energy levels or difficulty concentrating on an easy way out – to boost their energy levels and fat-burning capabilities via dietary supplementation with caffeine before exercising.

Hops Extract

Hip patients may tolerate an extract better than other medication-based weight loss plans. This is because it does not cause serious side effects such as dry mouth, increased heart rate, or high blood pressure. It is also non-addictive and can be used both short and long-term without risk of dependence or withdrawal symptoms.

When it comes to losing weight, studies show that hops extract may be just as effective as a structured diet and exercise plans – if not more so.

A randomized, double-blind trial at the University of Poone found that patients taking a standardized dose of hops extract for 12 weeks lost significantly more body fat than those taking placebo capsules. The study also showed hop extract had no adverse effects on vital signs or cholesterol levels.


Theobromine is a naturally occurring alkaloid found in cocoa plants and other food sources such as tea leaves, guarana seeds, and kola nuts.

In its chemical makeup, Theobromine consists of both caffeine and potassium ions; However, while caffeine stimulates mental alertness and boosts energy levels, Theobromine is considered to be more holistic in its approach. It aids digestion, boosts metabolism, and reduces fat accumulation in the body effectively – all essential requisites for weight loss.

Cayenne Pepper

A study published in the American Journal of Medicine & Science in Sports & Exercise in 2002 found that the inclusion of a daily dose of 6 mg of capsaicin (an active ingredient found in cayenne peppers) led to weight loss between 4-8kg over 12 weeks.

The authors concluded that capsaicin increased metabolic rate and energy expenditure, reducing body fat levels.

Another study published in the Journal of Nutrition Science and Vitaminology also investigated the effect of a daily intake of 6mg capsaicin on metabolic rate and body composition over 12 weeks.

It was found that participants who had taken a regular dose of cayenne pepper at breakfast time showed improved body composition profiles after three months.

In particular, a lower abdominal fat percentage was noted among those taking cayenne pepper compared with controls. This suggests that taking cayenne pepper regularly at breakfast may help reduce abdominal fat levels combined with healthy eating habits.
