PhenQ Review

Looking for a natural way to drop those excess pounds? PhenQ is growing popular as a supplement because it claims to tackle weight management in five ways.

Does it live up to the hype, though? Our PhenQ review covers how this fat burner works, from its ingredients, benefits, possible side effects, real user feedback, and much more. Let’s get the ball rolling!

What Is PhenQ?

PhenQ is a fat-burning supplement that aims to help men and women manage their weight. It combines natural ingredients, such as herbal extracts and vitamins, in a convenient pill form to promote weight loss.

How Does PhenQ Work?

PhenQ stands out thanks to its five-in-one approach to weight loss. It’s time to break down how it works!

Fat Burning

PhenQ helps blast body fat through its ingredients. For example, alpha-lipoic acid can rev up energy production, keep your body from storing extra fat, and encourage fat burning [1].

Aside from stimulating your muscles and nervous system, caffeine also speeds up your metabolic rate as you exercise, so your body can transform fat to energy [2].

Appetite Suppression

PhenQ features a-Lacy’s Reset that comes with cysteine, which may crush those cravings. It suppresses ghrelin (a.k.a. the “hunger hormone”) from being released by the stomach. So, cysteine is known to curb the appetite within 45 minutes [3].

Better yet, capsaicin may help you stick to a diet of low-calorie foods by making you feel full longer [4].

Blocking Fat Production

Some PhenQ ingredients can help your body from producing new fat. For instance, nopal was shown to prevent extra fat gain in mice that ate a high-fat diet. What’s more, nopal nurtures friendly bacteria to limit species that might cause weight gain [5].

Energy Boost

PhenQ also packs ingredients that may energize your body. As an example, L-carnitine moves fatty acids into mitochondria (the energy-producing hub of cells) to crank up more energy.

Moreover, piperine encourages fat loss by making your muscle cells absorb more fat, allowing L-carnitine to work better. Of course, caffeine both boosts perceived energy and increases its production in your muscle cells [6] [7] [8].

Mood Enhancement

Some PhenQ ingredients may help improve your mood. For instance, caffeine can boost your levels of dopamine (a.k.a. the “happy hormone”) [2].

Additionally, nopal could assist in uplifting your mood by balancing your intestinal bacteria and supporting neurotransmitter production [5].

How To Take PhenQ: Dosages and Timelines

What is the recommended dosage for PhenQ? The maker of PhenQ suggests taking two pills a day, one during breakfast time and another during lunch. To avoid disrupting your sleep at night, don’t take PhenQ in the evening as the caffeine might stimulate you.

It’s a good idea to take PhenQ diet pills for at least 60 days for sustainable, long-term results in losing weight. Research suggests that most people can break bad habits and strengthen new ones after around 66 days [9].

PhenQ Ingredients Breakdown

What’s inside the multi-action formula of PhenQ? Here’s a closer look at each ingredient!

A-Lacy’s Reset

As the star ingredient of PhenQ, a-Lacy’s Reset combines cysteine amino acid that delays your hunger and alpha-lipoic acid, which helps your body churn out more energy [3] [1].

This patented blend is supposed to increase metabolism by triggering thermogenesis, where your body’s temperature is slightly raised to burn fat.

Nopal

Nopal cactus is a Mexican cactus species that may prevent weight gain by relieving intestinal inflammation and limiting fat absorption.

Research suggests that intestinal inflammation might increase your body fat [10]. Thankfully, a trial shows that mice who were given nopal had less inflamed colons [5].

Another study suggested that nopal cactus can increase fat loss through feces. The participants who took nopal lost 15% of the fat they ate, compared to less than 5% in those who didn’t [11].

Caffeine

As a popular stimulant, caffeine revs up thermogenesis, leading to extra fat burning by boosting your cells’ energy production [8].

By raising noradrenaline (the “fight-or-flight hormone”) and dopamine (the “feel-good hormone”) levels in your brain, caffeine gives you more motivation to work out [8].

L-Carnitine Fumarate

While your body can make carnitine from other vital amino acids, carnitine levels drop with age. Thankfully, supplements like L-carnitine fumarate can encourage weight loss.

Carnitine helps transport free fatty acids to the mitochondria, also called the “power plant” of the cells. This can help you lose weight by increasing fat-burning and amping up your energy levels while you work out [6].

Chromium Picolinate

Chromium can help regulate your blood sugar levels, especially if you’re prone to type 2 diabetes or metabolic syndrome [12]. By boosting insulin function, this helps make your muscle cells absorb more sugar to create more energy.

Chromium may also increase protein synthesis, which could lead to greater muscle mass. Additionally, it might lessen your cravings for fatty foods [13].

Capsimax Powder

Capsimax is a concentrated form of red chili pepper extract. Capsaicin, which produces heat in capsicum extract, may suppress your appetite [4].

What’s more, a study shows that volunteers who took capsicum ate fewer calories than those who didn’t. Within six weeks, those who consumed capsicum reduced their waist-to-hip ratio [4].

Possible Side Effects

Is PhenQ safe? Yes, it is generally considered safe for most healthy adults. However, some users may experience mild side effects, such as:

  • Digestive issues

Talk to your doctor first before taking PhenQ if you fall under any of these groups:

Who Is PhenQ Best For?

PhenQ is ideal for healthy adults who are struggling to lose weight because of a slow metabolism, food cravings, or a lack of energy. It’s also a great choice for folks who want to try natural alternatives to prescription weight loss meds, such as Ozempic for weight loss.
