Our fitness experts decided to spend time doing thorough research and creating this Phen375 review to answer one of the most commonly asked questions about almost every popular fat burner, including this one:

Does Phen375 work? Is it an effective weight loss supplement or just another fat burning Internet scam?

We'd be happy to share our findings with you to help you resolve this dilemma in case you’ve been caught in it.

Here’s what you must know before deciding whether this fat burner would be right for you.

What Is Phen375?


Phen 375 is a fat-burning supplement you can buy without a prescription.

It helps your body speed up metabolism, lose weight, burn stored fat, reduce appetite and calorie intake.

It will make you look slimmer and feel healthier, happier, and more energized.

This product has over 250,000 satisfied users claim these diet pills with natural ingredients can do wonders for your figure in combination with a healthy diet and exercise.

Phen375 Ingredients


Now, let’s see the main active ingredients Phen375 fat burner formula for the US market includes, and what fat-burning results and other benefits they may provide.

(Note: The EU formula differs as it doesn’t contain Coleus Forskohlii Root and Dendrobium Nobile Extract.)


Phen375 formula consists of 68% L-Carnitine, an essential amino acid that helps your body create protein and turn stored fat into energy [1].

It’s also commonly used in weight loss supplements to speed up metabolism, fat burning, and recovery from exercise stress [2], and to reduce muscle pain and fatigue [3].

Check out the best l-carnitine supplements on the market.

Caffeine Powder Anhydrous

white pills and white powder

This powerful stimulant of the central nervous system helps to keep you mentally alert and more energized throughout the day.

Plus, it improves your athletic performance and endurance. [4]

It also suppresses appetite, increases your metabolic rate, and stimulates thermogenesis that makes you shred body fat for energy [5].

This helps you lose weight faster, especially when combined with other ingredients like Citrus Aurantium [6].

Coleus Forskohlii Root

The 10% of Forskolin, an active compound from the plant found in this diet pill, can improve your blood flow, mental performance, and libido.

It also helps L-Carnitine release the stored fat from your fat cells, promoting weight loss. [7]

But, it won’t work without a sensible diet and workouts.

Citrus Aurantium

citrus aurantium

Similarly effective in losing weight, this is one of the best thermogenic substitutes for controversial and aggressive Ephedra. [8]

Containing 10% of Synephrine, it safely and effectively boosts metabolism, weight loss and sports performance, specially when combined with stimulants like caffeine. [9]

Plus, it may increase your energy levels and suppress food cravings.

Cayenne Pepper

Thanks to the thermogenic properties of Capsaicin from Cayenne Pepper, this dietary pill can relieve muscle pain, reduce hunger and “bad cholesterol” levels, plus improve metabolic rate and efficiency, which results in losing weight, among many other health benefits. [10] [11] It's a known appetite suppressant in many fat burners and weight loss pill products in the market.

Dendrobium Nobile Extract

Dendrobium Nobile Extract

This extract derived from orchids improves immunity, digestion, stamina, and physical performance.

It also further enhances the energizing and weight loss effects of L-Carnitine, caffeine, and Capsaicin.

This anti-inflammatory herb [12] is also commonly used in Chinese medicine and as a pre-workout supplement [13].

Chromium Picolinate

Besides many other health benefits, when taken in small daily doses, this vital mineral aids in keeping your blood glucose balanced, blocking appetite (especially fat and sugar cravings), increasing lean muscle mass, reducing fat storage, and promoting weight loss. [14]

Calcium Carbonate

Now you may think: "Chalk in supplements can help me lose body weight? Really?"

Actually, it mainly acts as a bulking agent in such pills, but some studies also show that Calcium plays an important role in increasing fat breakdown and decreasing fat absorption. [15] [16]

Pros and Cons

  • Claims to reduce appetite, increase metabolic rate and energy levels to enhance fat loss effectively
  • Said to be 100% safe, produced in FDA-compliant labs using scientifically-proven, natural ingredients of high quality
  • Comes with a free customizable diet plan and exercise routine to help increase your muscle mass
  • Provides 60-day money-back guarantee
  • Higher price and the shipping isn’t free as for many other similar products
  • Although the product’s low in stimulants, they’re still powerful, so a sensitive customer should first consult a doctor to avoid experiencing potential adverse effects.

Any Side Effects?

To my knowledge, there have been no side effects caused by the use of Phen375 reported so far, which indicates that you should be safe if you don’t exceed the recommended dosage.

However, just like other weight loss supplements containing stimulants, including those naturally-sourced ones, some sensitive individuals who use Phen375 might experience potential mild side effects like:

  • Allergic reactions to some herbal ingredients
  • Headaches
  • Upset stomach and cramps
  • Nausea
  • Dizziness
  • Increased pulse rate and blood pressure
  • Jitters
  • Nervousness
  • Insomnia.

These adverse effects are rare, and most are due to the overuse of caffeine, so you can easily avoid them if you closely monitor your total caffeine daily intake. Otherwise, you can opt for a caffeine free fat burner.

“Caffeine is found in many beverages, including coffee, tea, energy drinks and colas, and in products containing cocoa or chocolate.”
