PhenQ says that, with them, “Getting the body you want is just a click away.”

This is quite impressive, but before I start clicking away to skinniness, I want to know:

Do PhenQ ingredients work?

So let’s take a closer look at one of the ingredients in PhenQ – α-Lacys Reset. This ingredient is said to help weight-loss in 5 different ways. The website focuses mainly on appetite suppression and fat blocking – this just isn’t enough for me, especially after considering the amount of ingredients in each capsule.

So what’s the deal here?

Find out more by reading these 5 facts you NEED to know about PhenQ.

Let’s plunge right in.

What is PhenQ?

To open with, PhenQ diet pills is boasted as a pharmaceutical-grade supplement for weight-loss. It is manufactured by ERGO Group Limited. According to the official website, this product helps elevate mood, boost energy levels, burn off stored fat, suppress appetite and block the production of fat. To use it, you must take one tablet with breakfast and one with lunch. You are encouraged to avoid taking this product after 3 pm, because it can interrupt sleep habits. It contains:

  • A-Lacys Reset
  • Capsimax Powder
  • Calcium Carbonate
  • Chromium Picolinate
  • Caffeine

PhenQ also contains Nopal (prickly pear cactus) and l-carnitine fumarate. Unfortunately, the actual amount of each ingredient is not disclosed. [1]

From what we gathered, Phen was released in 2015. This product is available directly from the official website, and a few customer testimonials are posted on the site. There is also a 60-day money-back guarantee presented but read on…

Insufficient Amounts – “A Consideration?”

First of all, PhenQ ingredients may not be added in adequate amounts. According to our Research Editor, “Although the official website does present the formula used in the tablets, the actual amount of each is not revealed. Naturally, this is a problem, because if slight amounts are used, then the supplement will likely be ineffective.” [2]

One user stated, “It doesn’t seem to help with weight-loss at all. Been taking it with diet and exercise, but no change so far.”

“The website doesn’t say how much of each ingredient is used. This is a problem for me,” mentioned another customer.

We did find PhenQ reviews that were a bit more positive.

“PhenQ helps suppress appetite in order to eat less and in take less calories to avoid excessive weight gain,” said a dieter. [3]

PhenQ Customer Testimonials

PhenQ Reviews – “Positive and Negative”

We found some customer complaints posted online for PhenQ. One user said, “Too big to swallow. Has not helped with weight-loss at this time, even though these are being taken with a healthy diet and exercise.”

“PhenQ does not work as claimed! It’s bogus. A lot of hype!” commented another customer.

While complaints are rare, we did locate some PhenQ reviews where customers shared their positive experiences. [4]

“Been taking PhenQ for a week now and have definitely lost my appetite. Weigh in this morning and lost 5lbs.,” reported a customer.

“I have been taking it for 1 week and the first thing I noticed was my loss of appetite. This product works so far I have lost 4 pounds and have more energy,” stated another.

According to our research, if there is some facet of a weight-loss supplement or diet program that is very concerning or burdensome (insufficient ingredient amounts, too many customer complaints, low Amazon rating) the likelihood of long-term success is quite small. This means if PhenQ does cause a lot of unhappy users, this could be a serious issue.

Any Solid Science?

We at DietSpotlight like to see some solid clinical research that backs up the weight-loss product’s claims. As for PhenQ results, there are some clinical studies presented on the company website. These studies pertain to the ingredients used. However, these are not very convincing, because we do not know how much of each is needed for actual weight-loss results, and we don’t know how much of each is used in PhenQ. [5]

The Bottom Line – Does PhenQ Work?

Now the moment you’ve been waiting for: our bottom line on PhenQ diet pills. First of all, we appreciate that this formula is sold with a 60-day money-back guarantee and there are some customer testimonials presented on the main website. Then again, we have some concerns because we do not know how much of each ingredient is used in this product. Also, we are a bit reluctant because of the customer complaints we found on the web.

If you’d like to get rid of some serious pounds, then we encourage you to choose a product that contains clinically tested ingredients for weight-loss, sells at an affordable price and is backed by plenty of encouraging user reviews.

Among the best products we’ve seen this year is our product called Dietspotlight Burn. The supplement uses a proprietary blend of four ingredients. All clinically-tested with results often found in publications such as the Journal of Medicine.

Also, we’re so confident that you’ll love our supplement that we’re offering a Special Trial Offer, which is a good sign.

PhenQ is a heavily marketed diet pill available all over the internet. The ingredients are listed on the official website, but we had to look elsewhere to find an actual label with amounts included in the formula. There are a few clinical references offered, but they include research into mood and exercise.

We thoroughly investigated PhenQ ingredients in order to provide you with the important facts and details.

α-Lacys Reset

α-Lacys Reset is an ingredient that contains both cysteine and alpha-lipoic acid. It has been around since 2013, and was developed by Nutraceuticals International Group.

What is it Supposed to Do?

The purpose of α-Lacys Reset is to accelerate the metabolism and elevate thermogenesis. This way the body burns off more calories at a faster pace. This in turn may lead to weight-loss and fat reduction.

Clinical Research

According to some research, “The volunteers involved in one weight-loss study lost 3.44% of their bodyweight and also showed a 3.8% increase in muscle mass.” However, this study was conducted by the company behind this ingredient. Therefore more research is needed to determine just how effective α-Lacys Reset is for weight reduction.

Clinical testing is a crucial factor to consider when it comes to selecting a diet supplement or weight-loss pill. You may want to take a look at a product like Dietspotlight Burn. This formula contains ingredients that are backed by real research.

Capsimax Powder

Capsimax powder basically comes from red-hot chili peppers. It’s often referred to as capsicum extract. While this ingredient has been used in a number of traditional medicines over the years, it’s also found in various over-the-counter weight-loss supplements.

What is it Supposed to Do?

Capsimax contains a key chemical called capsaicin. This component is supposed to help break down body fat, support a healthy metabolism and allow fat cells to be utilized as energy. It may also elevate your core temperature (boost thermogenesis).

Clinical Research

“A 2013 publication of PLoS One included a study in which participants consumed 2.6 milligrams of capsaicin once every 36 hours over a period of 144 hours. Researchers found that consuming capsaicin led to higher fat oxidation after meals and counteracted the slowdown in metabolism that usually occurs on a calorie-restricted diet. The capsaicin supplement also did not have any negative effects on blood pressure, and while the study showed great promise for capsaicin as a metabolism booster and fat burner, further research is needed.” [1]

Calcium Carbonate

Calcium carbonate is essentially a chemical compound that is found in limestone, shellfish, coral and marble. It’s often used in dietary supplements to help treat or prevent calcium deficiency. This is an important mineral for bone density and strength, as well as healthy muscle and heart function.

What is it Supposed to Do?

Often calcium carbonate is used in diet supplements and weight-loss products to help reduce fat storage. It’s often combined with other key ingredients to aid with weight reduction. [2]

Clinical Research

“A study in 2000 at the Osteoporosis Research Center of Creighton University looked at 780 women who participated in double-blind, placebo-controlled studies of calcium supplements. In four years, the women who took 1,000 mg of calcium a day weighed, on average, 3.5 lbs. less than women who did not take the calcium. Researchers concluded that the calcium was responsible for 3 percent of the body weight variance, or about 0.1 pounds.”

We are all about limiting the risk of side effects when it comes to trying new weight loss products. One supplement we’ve been noticing in particular, Dietspotlight Burn, has four-salient ingredients proven in studies to burn fat, boost energy levels and ignite the metabolism.

PhenQ Scientific Abstracts:


At the 12th week and at the 14th week there had been no significant changes in variables between the groups. There had been no raise in lean mass in the calcium group by the 12th week in comparison to baseline and placebo group at the 24th week in comparison to the 12th week. There had been a noticeable reduction of insulin concentration in the calcium group at the 12th week when compared to baseline (p < 0.05). The diastolic blood pressure had a substantial reduction at the 24th week in comparison to the 12th in either groups (p = 0.013-0.009). In conclusion, the results had indicated that 24 weeks of treatments with 1000 mg ca/d didn’t display any effects on weight, insulin resistance, blood pressure, and body composition. [1]


Measurements of strength had been improved for all groups (p<0.05), with no notable time x treatment interactions. No substantial main effects were observed for peak power. As for total power, a time x sprint interaction had been noticed (p<0.05), with no substantial interactions between the groups. A time x treatment interaction had been noticed for serum CRN values (p<0.05) which pointed out a raise in all groups with the exception of PLA. Participants had noted mild gastrointestinal discomfort with caffeine anhydrous/creatine mixture with no side effects in the other groups. It had thus been suggested that neither creatine by itself or in combination with caffeine anhydrous or coffee had a noticeable effect on performance when compared to placebo. [2]

L-Carnitine Fumurate

Bone volume and total volume ratio, osteoblast surface/bone surface, bone perimeter, and osteoblast number/bone surface had all been measured. Bone volume and total volume ratio as well as all osteoblast-based indexes had been a lot higher in LC and Iso-V LC than in Hypo mice at the given time points, and Iso-V-LC at the completion of treatment reached levels studied in controls. In conclusion, Iso-V-LC and LC accelerated the recovery of normal bone volume/total volume levels following a hypocalcemic diet. [3]

Capsicum Extract

Within an effective 20.5% negative energy balance, ingestion of 2.56 mg capsaicin per meal promotes negative energy balance by successfully counteracting any negative effect of reduction in elements of energy use. In addition, the ingestion of 2.56 mg capsaicin per meal had aided fat oxidation in negative energy balance and doesn’t raise blood pressure by any substantial amount.


Niacin, being available in the form of 3 options (immediate release, extended release, and long acting) is significantly different with respect for their efficacy and safety profiles. Immediate release is known to have adverse flushing, elevated blood glucose and gastrointestinal symptoms. The long acting variety can be taken once per day and is associated with substantially decreased flushing; however its metabolism does raise the risks of hepatotoxic effects. Extended release niacin, which is also suggested to be taken daily, has an absorption rate somewhere between the other formulas. It is associated with fewer flushings and gastrointestinal symptoms and doesn’t raise the hepatotoxic risk. [4]

  • Christina Murphy

    I took it the last two days (as directed) and I’ve never felt more horrible: Nausea, EXCRUCIATING HEADACHE, and I couldn’t sleep. Sure, I had a loss of appetite…..because I felt like I was literally DYING. Never taking this again

    • Leana

      Your so right headaches, nausea, anxiety I felt like I was also dying and it lasts till the next day. I’ll try one a day but if I feel like that again I’m done.

    • Jenn

      Are you used to drinking coffee?? Maybe that’s why you have the headaches..

  • Jeannine

    I am now on the second bottle and I dont see any difference.

    • Victoria (Editor)

      Hi Jeannie. We’re sorry you didn’t achieve any results with this product; you might have reached a plateau. If that’s the case, you might want to look into products that help with speeding up your metabolism and suppressing appetite. Have you checked out Dietspotlight Burn?

  • Stomach has been hurting
    Charlotte Butler (Verified User)

    started taking it yesterday 11/10-16 my stomach has been hurting, since then, will not take anymore, just not for me

  • So far so good!
    Lena (Verified User)

    I’ve been using PhenQ for 2 days now and so far I’ve completely lost my appetite which is good because before I could eat the house down, and it’s helped me get rid of whatever I eat.. If you catch my drift. So far so good!

  • I wonder if it's effective

    I wonder whether it’s effective because we are encouraged by Phenq to go on a 5:2 diet anyway and take it at the same time so how is the pill making me lose weight when the 5:2 diet is being done at the same time. I can lose weight with 5:2 easily if it stick to it. I expected Phenq to increase the weight loss with the diet. I lost 1.5kg last week & started taking the tablet from Tuesday. on the wkend I had a dinner on and lunch, I put 0.8 kgs while still taking the pill. means that the diet works but the pill is not doing much

  • Horrible side effects
    Denise (Verified User)

    I’ve been using Phenq for two days now. It’s horrible, I sweat all the time. My heart rate is up, I feel dizzy, I don’t sleep. This is not a good product!

    • Your Name

      You should start by just using one it’s takes a while for some people to get use to it .

      • Natasha

        ive ordered my first bottle last Thursday but your dizziness is probably cos you need to exercise it out your body needs it and your heart rate is up cos your burning fat

  • No change in energy or mood.
    Becca (Verified User)

    I’ve been taking PhenQ for a few days and I don’t feel any sort of energy or mood boost. Actually the opposite. I have this dull headache behind my eyes and I’m grumpy. This could also be because I’m trying to cut out the sugar in my diet too. Going to keep taking it until I have used the whole bottle. Not going to bother with returning it. Will follow up if I notice any difference or see results.

    • Victoria (Editor)

      Hi Becca! If you’re looking for products that can assist you with more energy throughout the day, you might want to consider products with caffeine and energy-boosting ingredients. Have you checked out Dietspotlight Burn?

  • 2nd day,so far it's good.
    Jenn (Verified User)

    This is my second day using it. Been using the restroom alot. But it might be because im drinking lots of green tea as well. I do sweat alot. But the appetite is gone. Been drinking lots of water. No headaches. No stomache pains.
