Workout crazes come and go. Diet fads run their course. One thing that has never gone out of style is the desire to lose weight. For decades people have fought to shed excess pounds, reduce their waistline, and see a lower number on the scale. 

That’s why, 70 years ago, scientists created Phentermine to help solve all these problems. This drug is designed to induce quick weight loss but, like many medications, comes with the risk of harmful side effects. 

For this reason, many people are seeking out safer alternatives to help them lose weight. Numerous companies are working to fill this need by producing natural supplements to replace the use of Phentermine. In this article, we will share some of our favorite recommendations for supplemental alternatives to Phentermine.

What is Phentermine

Phentermine is a prescription grade appetite suppressant used to decrease hunger and increase metabolism. It has been prescribed since the 1950's to individuals who are considered medically obese. While it has proven to be an effective method for weight loss, Phentermine can be accompanied by potentially dangerous side effects. For this reason, it must be prescribed by a doctor and is only approved for short term use.

Side effects of Phentermine range from mild issues such as dry mouth, nausea, irritability, and trouble sleeping to more dangerous reactions like heart complications or psychological disturbances (1). 

Unfortunately, there are no approved alternative medications or over the counter drugs to take in place of Phentermine. Note, products claiming to be Phentermine clones should be avoided; they are not regulated and there is no guarantee they will be effective or even safe. Additionally, obtaining Phentermine, or any product labeled as such, without a prescription is considered illegal.

Natural Phentermine Alternatives

Rather than take your chances with risky and hard-to-get medications like Phentermine, we suggest using an all-natural, legal supplement as a replacement. Many nutritional companies produce safe alternatives using vitamins, minerals, and other natural ingredients to help you shed excess weight and reach your fitness goals. 

In this article, you’ll find three of the top all-natural supplements on the market. Each product was designed to give you the powerful metabolism-boosting, appetite-suppressing results you’ve been looking for. We’ve done the research, and these supplements come from trusted companies who utilize safe, effective ingredients so you can feel confident using their products.

PhenQ: Best Calorie Burner

Wolfson Brands (UK) Ltd, a trusted nutrition company, has been producing health supplements for over 10 years. They designed PhenQ to address weight loss needs across the board. Advertising itself as being five supplements in one, PhenQ offers weight loss support on all fronts—burning fat, decreasing fat production, suppressing appetite, boosting energy, and improving mood.

Using powerful thermogenic ingredients, PhenQ’s formula fires up the metabolism, helping the body to utilize calories and fat stores in order to curb cravings and maintain energy levels. To increase these results even further, PhenQ implements their effective, trademarked, secret compound 𝛼-Lacys Reset.

Containing naturally occurring antioxidants, 𝛼-Lacys Reset is backed by research showing it is highly effective at accelerating your metabolism and promoting thermogenesis—enabling your body to burn fat quickly and achieve your fitness goals. 

Using PhenQ is simple, just take one capsule every morning at breakfast then another capsule during lunch. Wolfson Brands recommends taking PhenQ by 3:00pm so the caffeine doesn’t affect your sleep.

A single bottle of PhenQ is $69.95 on their website. However, you can receive discounts when the product is bought in bulk. The company lists their most popular option as buying 2 bottles and getting one free.
