How We Ranked Best Phentermine Alternative Supplements For 2021?

There are hundreds of phentermine alternative supplements available in the market, and all claim to be effective, natural, and safe for weight loss. However, many of these claims are invalid.

We know that it is puzzling for you to choose the right supplement; therefore, with thorough research, our team has formulated a list of the top phentermine alternative pills based on the following ranking factors.

Scientifically Proven Ingredients

Numerous studies have been carried to test the beneficial ingredients for weight loss, suppressing appetite, burning fat, and maintaining a good physique. However, some false companies add artificial ingredients that are ineffective and offer a placebo effect. We rank the phentermine supplements that include science-backed components.

Effective Dosages

A supplement can work best if its ingredients are added in optimum dosages. The pills with low dosages cannot perform efficiently. For example, many companies add more than ten beneficial ingredients in clinically ineffective dosages. So, we rank the phentermine alternative supplements that contain clinically effective dosages of science-backed ingredients.

Honest Advertised Benefits

Many manufacturers make false claims; they market their supplements with unrealistic benefits, such as losing 30 pounds within a week, which is impossible. Even phentermine itself cannot help you lose 30lbs in a week. Also, the best supplement can help in reducing weight in conjunction with a healthy diet and exercise.

Manufacturer Transparency

We include the companies and manufacturers in our list that are transparent in disclosing all the ingredients, the dosages, customer reviews, and all the information related to the supplement. If the manufacturer does not mention the components or the dosages, they might be using low-quality ingredients.

Company Reputation

Some companies have had a reputation for producing efficient and high-quality supplements for decades. Meanwhile, some new companies are scams. We rank the companies with a positive record of making the best phentermine supplements.

Refund Policy

Many companies on this list offer zero-risk purchases with a money-back guarantee and return policy. If a particular supplement does not help you reduce weight, you must have a chance of getting a refund. Thus, we like the companies that offer a money-back guarantee to their customers.

Price Of The Product

We add phentermine alternative supplements in different price ranges, but all offer good value for the money spent. We believe that the phentermine alternative supplements should be affordable and pocket-friendly for you. Thus, from our list, you will get the top phentermine alternative supplements in your budget whether you want to spend fewer dollars or hundred dollars.

Doctors Formulated Supplements

Expert doctors and health professionals formulate the best phentermine supplement. They use their knowledge and clinical experience in creating effective and safe formulas. We, therefore, prefer the formulas made by a medical advisory board containing doctors and professionals.

Lab Testing

The best supplement-producing companies invest in lab testing and third-party verification of their supplements. Lab tests ensure that the formulas are effective, safe, and potent to use. Also, lab testing is vital as many false companies use artificial ingredients that are unsafe to consume.

We use these essential factors to rank products in our best phentermine alternative supplements list.

What Is Phentermine?

Phentermine is an FDA-approved prescription medicine for weight loss. It gained utmost popularity in the 1990s.

Many people consume phentermine with other medications to quickly and safely lose weight.

Some of the most famous phentermine brand names are Suprenza, Adipex – p, and Lomaira. One other weight loss drug named Qsymia also contains phentermine as a critical ingredient.

So, what are you thinking? With phentermine, is the weight loss journey so accessible?

No, phentermine is not for everyone to lose a few vanity pounds.

It is a prescription medicine and is not available over the counter to be purchased by anyone. It is only for those patients who are obese or have a BMI of 30 or suffer from weight-related diseases.

According to the American Academy of Family Physicians, phentermine is used by those who have 20 percent or more weight above their ideal body weight.

How Does Phentermine Work?

Phentermine (you can find under the brand names: Ionamin, Adipex, and Suprenza) helps in weight loss by suppressing appetite, reducing your craving for food, ultimately helping you eat less. By maintaining a caloric deficit diet, it helps you in losing weight rapidly. But it is only approved for short-term use.

Moreover, phentermine targets neurotransmitters in your brain to reduce appetite. According to history, phentermine raises serotonin, norepinephrine, and dopamine levels. Usually, these hormones release after eating. By increasing the levels of neurotransmitters, phentermine trick your body to believe that you have already eaten food.

Who Should Consume Phentermine Alternative Supplements?

Probably you think if you do not come in the category of patients in line for a prescription of phentermine, are there any other alternatives? Yes, phentermine alternatives are advertised to those who want to kick start their weight loss goals.

You can consume phentermine alternative supplements if:

  • You are trying to lose weight.
  • You are trying to break a frustrating plateau.
  • You are trying to hit the target weight.
  • You want to look the best.

Does Phentermine Alternative Supplements Pose Side Effects?

Mainly, healthy adults do not experience any adverse effects due to phentermine alternative supplements. According to the FDA, the supplements must contain generally recognized as safe (GRAS) ingredients. These ingredients are safe to use by healthy adults.

However, some people may experience minor side effects such as diarrhea, nausea, constipation, and headache.

Also, other people experience dry mouth, dizziness, irritability, insomnia, and anxiety from consuming phentermine.

Note that you must consult your doctor before consuming any phentermine alternative supplement to avoid side effects.

Dosage Of Phentermine Alternative Supplements

According to research, phentermine works at a dose of around 27.5 mg. More specifically, it is linked to 13.9lb weight loss at this dose within 13 weeks.

On the other hand, phentermine alternative supplements do not contain phentermine; instead, they have additional weight loss ingredients. Thus, follow the recommended dosage instructions mentioned on the packaging of the supplement you use.

Most supplements are taken as one or two capsules per day or one to two scoops of powdered formula.

Also, check the caffeine amount in the supplement. Most supplements contain around 200 mg to 300 mg of caffeine, equaling three cups of coffee. The average coffee cup is rich in 80 mg to 120 mg of caffeine.

Benefits Of Phentermine

Phentermine is an FDA-approved prescription medicine that is linked to various benefits. Most people consume it for weight loss, but it also offers other benefits.

According to the studies, phentermine can offer the following benefits:

  • Weight loss.
  • Control blood sugar levels.
  • Helpful for eating disorders.
  • Control cholesterol levels.
  • Decrease waist circumference.
  • Improve insulin sensitivity.

How Much Weight Can One Lose By Consuming Phentermine?

Most individuals lose around 5% to 10 % of their body weight by phentermine supplements.

Participants lost around 13.9lbs over 13 weeks on phentermine in a review study.

Although phentermine alternative supplements are not as powerful as phentermine, they help lose weight in conjunction with diet modification and exercise.

Some supplement companies claim that consumers lost around 30lbs to 60lbs of weight with their phentermine alternative supplement. These claims may be unrealistic, but you can enhance weight loss by consuming phentermine alternatives combining it with other medications such as topiramate that reduces hunger.

What Do Clinical Trials Suggest Regarding Phentermine?

Many pieces of research and clinical studies prove the beneficial effects of phentermine.

Researchers concluded that individuals lost around 10% of their body weight over 12 weeks of phentermine consumption. A similar study further suggests that participants lost around 13.9lbs by consuming 27.5 mg of phentermine for 13 weeks.

A study shows that the combination of phentermine and topiramate maximizes the weight loss benefits. One supplement that combines these ingredients is Qsmyla and is recommended by many doctors.

In one study, researchers found that phentermine and topiramate decreased waist circumference, decreased blood pressure, improved lipid profile, especially triglycerides and high-density lipoproteins, improved insulin sensitivity, and decreased the progression to type 2 diabetes. The same study also found that these ingredients pose side effects such as dry mouth, paresthesia, constipation, dysgeusia, and insomnia.

Doctors also prescribe phentermine supplements to people with eating disorders. A 12-week study suggests that a combination of phentermine and topiramate substantially reduces weight, body mass index, and binge eating in people with binge eating disorder (BED). In another study, researchers concluded that participants decreased binge eating days from 16.2 to 4.2 after 28 days of phentermine and topiramate consumption.

Remember that whether you are consuming phentermine or phentermine alternatives, you will get more benefits if you follow lifestyle changes and a healthy diet. As per science, the best ways of losing weight include:

Eat a balanced diet; that means choosing low-calorie and nutrient-dense food. Select foods that are rich in fiber, minerals, and vitamins.

Perform daily exercise. Experts suggest that 150 minutes of moderate aerobic activity per week keeps you healthy and helps to lose weight.

Make lifestyle and behavioral changes. Monitor your food intake, perform an exercise, and breathe in the fresh air.

Phentermine intake is not recommended if you have hyperthyroidism, heart disease, or a nursing mother.

How Do Phentermine Alternative Supplements Work?

Phentermine alternative supplements do not contain phentermine and are not chemically similar. Only a similar property is to help lose weight.

Phentermine alternative diet pills are rich in scientifically proven ingredients for weight loss. Some supplements contain caffeine or green tea extract (Java Burn has it). At the same time, others include Oleuropein and capsaicin.

Also, a few phentermine alternatives contain appetite suppressants to reduce hunger and food cravings.

We consume caffeine in tea or coffee regularly, but we don’t know its weight loss benefits. There is a reason why phentermine alternatives contain caffeine. It is a proven ingredient to boost metabolism, burn calories even at rest and lose weight. Some of the best phentermine alternative supplements add around 200mg of caffeine or more which equals two cups of coffee.

In a systematic review of 2019, researchers analyzed the relation between caffeine and weight loss with the help of randomized controlled trials. Researchers concluded that caffeine consumers had reduced weight, decreased BMI, and fats. The participants lost around 17% to 28% more weight than the placebo group. Also, on doubling the dose of caffeine, the effects of weight loss doubled.

Did you notice above that phentermine alternative supplements also contain capsaicin as the main ingredient?

Capsaicin is an active ingredient derived from cayenne pepper and is linked to excellent weight loss. A 2017 study suggests that capsaicin is linked to anti-obesity effects and doctors recommend this ingredient to obese individuals.

Additionally, in a 2018 study, researchers found that capsaicinoid supplements raised metabolism and thermogenesis and boosted calorie burning and fats, thus helping lose weight.

Nowadays, green tea is a popular beverage that people use to lose weight. There are numerous benefits green tea extract offers, so it is added in many supplements targeting weight loss. Green tea extract helps shed weight by fat oxidation, increasing energy expenditure, reducing lipogenesis, and decreasing carbohydrates absorption and digestion.

Phentermine works by suppressing appetite. Like phentermine, another best way of appetite suppression is the consumption of fiber supplements. Fiber absorbs water in the stomach, giving the feeling of fullness. Thus many experts recommend taking fiber for weight loss. In a 2019 study, researchers suggest that fiber makes it easy to follow a calorie-restricted diet, helping to lose weight quickly.
