How Does PhenQ PM Work?

The PhenQ PM brand website is considerate enough to offer clients vital information they need before they start using the supplement. The website explains how the supplement works based on the duration of consumption:

In The First 24 Hours

Upon taking PhenQ PM, the all-natural ingredients in the capsules will prime your body for fat-burning sleep. This can help you tackle resting calories even while you rest.

In 2 Weeks

As your body becomes more adept at utilizing the three stages of fat-burning, you may see some positive changes in your body and overall well-being. These can include reduced cravings, increased energy levels, and feeling lighter.

By consistently using PhenQ PM, you can help your body continue to burn fat even while you sleep. This can lead to significant weight loss and improved overall health in the long term. As you continue taking PhenQ PM, you can lose weight and feel confident in your appearance. 

Who Should Use PhenQ PM?

Nighttime fat-burning supplements like PhenQ PM may be appropriate for supporting healthy fat loss and deep sleep. These supplements boost the body’s natural fat-burning processes during the night, making it easier to shed excess pounds and achieve weight loss goals.

However, it is important to speak with a healthcare professional to ensure that a nighttime fat-burning supplement is appropriate for your individual needs and health status. PhenQ weight loss pills may be a helpful addition to a weight loss plan for those seeking a natural, supportive option.

Regardless, people under 18, pregnant or breastfeeding women, and people suffering or predisposed to certain diseases are discouraged from using fat burners.

PhenQ PM Ingredients 

The PhenQ diet pills nutritional fact sheet is difficult to find on the site, but the good thing is that it still explains what the individual ingredients do for the human body. Its active ingredients consist of vitamins, minerals, and natural amino acids. The formula comprises all-naturally sourced soy, dairy, gluten, and preservative-free ingredients, but the fine print identifies synthetic food dye and anti-caking agents.

Here is the ingredient list in the PhenQ PM dietary supplement that claims to help with reducing night sugar cravings and fat accumulation while boosting metabolism.


L-arginine is an amino acid that may have several potential benefits for weight loss, including its ability to boost human growth hormone[1] levels in the body. Growth hormone has been shown to reduce obesity by acting on two enzymes that control the breakdown of stored triglycerides[2] — lipolysis and fat accumulation — lipogenesis. These enzymes are lipoprotein lipase and hormone-sensitive lipase.

In addition to its effects on these enzymes, L-arginine may boost the body’s metabolism, increase fat burning during exercise, reduce waist[3] circumference, and increase muscle mass.

L-Lysine HCL

This is an essential amino acid that helps with carnitine synthesis.[4] When you start taking PhenQ PM, the carnitine[5] aids in transforming fat into energy, which can result in a healthy reduction of excess weight and fat, leading to an increase in energy.


The third amino acid in the PhenQ PM formula is L-theanine. This amino acid is particularly helpful in reducing stress-related[6] habits like snacking, and it also promotes deep sleep. Stress can be a major obstacle in weight loss efforts because it can lead to late-night snacking and other unhealthy behaviors.

L-theanine may help ease the brain into a relaxed alpha state,[7] similar to meditation, which can prime it for deep sleep and fat burning. This can be especially beneficial for those using a fat burner like PhenQ PM as a deep sleep remedy, as it is an important component of the fat-burning process. 


5-HTP,[8] a precursor of the hormone serotonin, may help fend off cravings and binges. Serotonin is often referred to as the feel-good hormone because it is involved in mood and stress management.

By supporting the production of serotonin, 5-HTP may help to regulate appetite and cravings, leading to more positive weight loss results. For these reasons, 5-HTP may be effective in reducing body weight in combination with exercise and a healthy diet.


Chromium is a mineral that may have potential benefits for supporting healthy blood sugar levels[9] and the natural fat-burning process. When blood sugar levels are stable, it can be easier to resist cravings and late-night snacking. Chromium may also help to enhance fat metabolism,[10] which can help the body burn fat more efficiently for energy.


Biotin, called vitamin B7, is important in metabolism[11] and purportedly supports the fat-burning stages during sleep. By boosting the body’s metabolism, biotin may help the fat incinerators burn calories while asleep. Biotin is often included in formulating the best diet pills as it may help support healthy weight loss.

Please note that the biotin research cited on the company website was from a study done 16 years ago; the fact that biotin was studied in combination with chromium may make conclusions about biotin in burning fat irrelevant.


Molybdenum[12] is a trace mineral important in only four enzymes,[13] one of which supports liver detoxification function. The brand claims that it clears out cortisol build-up. Cortisol is a stress hormone linked to weight gain and obesity, but there seems to be no scientific evidence that supplementing it increases cortisol clearance.

Vitamin C

Vitamin C is on the PhenQ PM ingredients list with potent immune-boosting properties.[14] It also serves as an anti-inflammatory. 

Vitamin B1

Vitamin B1 — thiamine — is a common ingredient in most fat-burning formulas that helps with the conversion of carbs and lipids to energy[15] while you are at rest. With increased energy levels, you get through strenuous workouts where you hasten the natural fat-melting process as you gain mass to reach a healthy weight.

Vitamin B6

B6, also called pyridoxine, is a mild diuretic, leading to reducing water weight,[16] and it also acts as an anti-inflammatory.[17] The company website purports that B6 deficiency may lead to increased sugar cravings, but this is only indirectly indicated in the reference article[18] cited to support this.

Vitamin B5

Vitamin B5 — pantothenic acid — activates lipoprotein lipase,[19] an enzyme that helps to burn fat cells. It may also help to reduce hunger and cravings when dieting, working alongside other B vitamins to support stress management and promote restful, fat-burning deep sleep.


Last but not least PhenQ PM’s natural ingredient is choline,[20] a trace mineral. Choline aids in the effective metabolization of lipids, which may aid in the prevention of diseases like fatty liver and excessive blood fat levels. 

A higher level of satiety brought on by this effective fat metabolism may also result in lower calorie intake and total weight loss.

PhenQ PM Reviews: What Do Real Users Say?

There are many nighttime fat burner reviews online on various sites such as the brand’s websites, Amazon, and Trustpilot.

When analyzing if the pills or powder used as a nighttime fat burner drink are potent, always go with unbiased information, typically on third-party sites. Most brands sieve the negative comments on their website and only display the good remarks.

I’ve been on every diet in the world and I haven’t lost any weight. PhenQ PM is actually working. But the best part is, it has given me more energy. I take fewer naps. And I don’t eat as much sugar or crave as much sugar.

Linda E.

When we switched gears and looked at TrustPilot’s PhenQ reviews, we only found general ones that spoke about the company. The story here is different, as most comments are on poor customer service and late or missing deliveries, and one comment about PhenQ PM was that it did not work.

Purchase three bottles of the diet supplement PhenQ… Total waste of money. It claims to curb appetite. Speed up metabolism. Provide energy for easier weight loss. Quicker weight loss. Did not. I repeat did not curb my appetite. As a matter of fact, 20 minutes after taking the pills. I’m famished completely starving with my stomach growling and everything useless pill. A waste of money does not recommend it great if it worked for you. It did not work for me and this is my experience with every weight loss supplement I have ever purchased. It’s a trap.


Final Thought

To be named the best nighttime fat burner, the product should have a list of natural ingredients, be allergen-free, and offer tangible evidence for all its claims. Herein are problems: there are synthetic ingredients listed in the fine print of PhenQ, but no actual label can be found for the PM product before purchasing. The evidence cited in the sources is often either outdated or irrelevant. No doubt these are all useful ingredients, but it may be a stretch that they do all the things claimed.

As seen in what real users say about the makers of these nighttime fat burner pills, their customer service, delivery, and effectiveness are greatly questioned. The good news is that you have three alternatives if this brand is unsatisfactory. But remember, read reviews about those supplements as well and consult a registered dietitian. Supplements related to burning fat should be suspect till proven otherwise.
