PhenQ contains a trademarked mixture called a-Lacys Reset, as well as a whole host of ingredients that are proven to have positive effects on weight loss. We really like that this supplement has a money-back guarantee, and that the company seem to be reputable. Shipping is free worldwide too, which is always a nice little bonus.


  • Looks reasonably safe
  • Company will not rip you off or sign you up to dodgy billing agreements
  • 60-day money-back guarantee


  • Somewhat expensive for one month’s supply when paying full retail price
  • Not many customer reviews to support claims
PhenQ contains some interesting and unusual ingredients for weight loss, but will the results work in the way that the advertising describes? Furthermore, is it actually safe?

We take an in-depth look into PhenQ to find out more.

PhenQ Overview

What you need to know about PhenQ

PhenQ appears to have been reformulated in the last few years. The principle ingredient used to be calcium carbonate, but is not a trademarked ingredient called a-Lacys Reset. The other ingredients are ones that tend to have some positive effects.

What are the side effects of PhenQ?

According to the product website, there won’t be any. But there is always a risk of side effects with ingredients such as caffeine and capsicum. Nothing too major though; potentially headaches, nausea, excessive sweating, jitters, etc.

How much does PhenQ cost?

One bottle of 60 capsules (1 month’s supply) costs £45.95. The website states that the usual retail price is £53.95, so the lower price may not be a lasting one.

Buy two bottles and get one free (3 month’s supply) for £91.90. Full retail price is listed as £161.85.

Buy three bottles and get two free (5 month’s supply) for £129.95. This option comes with a free bottle of another supplement called Advana Cleanse, (retail price is listed as £269.75).

PhenQ Key Features

PhenQ is following a diet pill tradition by using “Phen” as part of the name and popping the words “In Phentermine Q” on the label. “Phen” is in reference to Phentermine – a notorious but powerful prescription drug that has helped people lose weight, but is known for side effects, including a link to strokes and heart attacks. These days, Phentermine is not so easily available and possibly, for this reason, there are numerous weight loss supplements on the market such as PhenQ which pay homage to the Phentermine name.

A “Phen” diet pill usually contains a lot of stimulants. However, PhenQ does not follow this trend and in fact, it is unlike any diet pill we have ever seen. The only stimulant ingredient is caffeine, containing around the equivalent of a cup and a half of coffee.

PhenQ Key Points

  • Each bottle contains 60 capsules (30 daily servings)
  • Free worldwide shipping
  • Manufactured by Ergo Health Group

Other ingredients include amino acids and vitamins, which may help with fat burning and increasing muscle mass. There are also some servings of weight loss ingredients such as capsaicin extract, which is believed to work as a natural thermogenic (fat burner), a natural cactus extract called Nopal, and chromium picolinate.

How to Take PhenQ

  • Take one PhenQ pill with your breakfast and one with your lunch every day for two months in order to achieve the desired result
  • If you need to lose a lot of weight, it is recommended to take the supplement for three months
  • Do not exceed the recommended dosage

PhenQ is manufactured by Ergo Group Ltd, an investment group based in Dubai. The group invests in sectors including health, wellness, technology, and energy. PhenQ is manufactured in FDA approved facilities, however, there is no further information as to whether PhenQ is made in the UK or the USA.

Although PhenQ comes from a Dubai-based company, there are offices in the UK and USA that deal with shipping and customer services in both countries. The company also ship internationally, and the product website is available in many different language versions.

PhenQ Concerns

  • There can be side effects to taking calcium carbonate
  • Many people consider calcium carbonate to be a filler ingredient

We have covered an Ergo supplement in a previous review. This was Garcinia Cambogia Extra, which we were impressed with.

What does PhenQ claim to do?

According to the advertising, there are six key features about PhenQ that will give you the “slim sexy body you’ve always wanted”:

  • Unique new slimming product designed to give you better results than others
  • Burn stored fat and reveal your hidden dream body
  • Suppress your appetite to eat less and cut calories
  • Block fat production to stop weight gain
  • Improve your mood and energy levels for hassle-free weight loss
  • High quality formula produced in the US and UK in GMP and FDA approved facilities


PhenQ makes losing weight straightforward, simple, and saves you spending on several products!

The supplement comes with a full 60-day money-back guarantee so:

you can purchase with absolute confidence. Simply return any unused PhenQ in its original packaging within 67 days of receiving your order and we’ll give you a full refund, excluding any shipping charges.

Does PhenQ work?

It may well do. We don’t have that much information about the branded ingredient a-Lacys Reset yet. But caffeine and capsicum extract in particular are decent ingredients. We think that you could expect to see some results with PhenQ.

phentatrim bottle
The most popular appetite suppressant in 2021 is Phentatrim.

Its ingredients are scientifically proven to aid weight loss and you are covered by a full 60-day money-back guarantee from a trusted company, making Phentatrim a very popular choice in the diet world.

Phentatrim is the best thing to hit the supplement market in a long time, with thousands of customers already seeing the benefits. That’s why it's our editor's top pick.

PhenQ Ingredients

PhenQ is a multi-purpose weight loss supplement. Serving size is equal to one capsule.

a-Lacys Reset

This is a trademarked formula that is said to speed up the metabolism and increase thermogenesis for accelerated fat burning. Although PhenQ call it their “secret ingredient”, we found some information online stating that it is a combination of ALA (Alpha Lipoic Acid) and cysteine.

Capsimax Powder

At high levels, capsaicin, the compound in chilli peppers which is the cause for the fiery effect, can be an effective thermogenic. Some evidence suggests that capsicum can increase body temperature and metabolism for 30 minutes after eating. Also included in this mix is piperine, caffeine and niacin (vitamin B3).

Chromium Picolinate

Natural trace mineral which means that your body requires very little. In addition, chromium plays a role in the regulating of blood sugar and insulin. Chromium Picolinate may help prevent sugar cravings, and it is being investigated as a treatment for diabetes.


Same as the caffeine in the coffee you drink but in powdered form making it more suitable for supplements. Can increase the metabolism and as a result, lead to weight loss although effects can wear off as you get accustomed to use. Amount here equivalent to about one and a half cups of instant coffee.


This cactus fruit extract is a source of the mineral manganese. Early research suggests it may affect blood sugar levels and may be effective for diabetes treatment.

L Carnitine Fumarate

A stable form of amino acid L Carnitine which is present in meat, nuts, and some veggies, and it is important for muscle building and combating fatigue. L Carnitine is often taken by bodybuilders for this reason.

PhenQ Side Effects

Potential may include:

  • Constipation
  • Nausea/vomiting
  • Gas
  • Mental confusion
  • Headaches
  • Thirst
  • Jitteriness
  • Anxiety
  • Itchiness
Not suitable for individuals under 18. Avoid if you are pregnant or breastfeeding. Seek advice from your doctor before taking if you are taking prescription medication or suffer from an underlying health condition.

PhenQ Customer Feedback

There is very little independent feedback for PhenQ, despite the high number of customer reviews on the product website. Unsurprisingly, all of these are extremely positive.

Here is a typical example from a customer, who has reported a loss of 7lbs:

I always hated having my picture taken – I used to try and hide behind other people in photos. I had to hold my stomach in all the time, and every time I sat down I’d have to cover it with my arms so people couldn’t see it. Now I don’t have anything to hide, and I love having my picture taken!

We could only find one Independent customer review, however, this was not as favourable. This lady had issues with the size of the capsules and the lack of effects. She reported:

Too big to swallow. Has not helped in weight loss at this time even though these are being taken with a healthy diet and exercise.

PhenQ Money-Back Guarantee

PhenQ does come with a guarantee if you buy directly from the official website, and it looks good.

Here is what the company have to say about it:

We offer a 60 day money back guarantee, so you have nothing to lose but your weight. Simply return any unused PhenQ in its original packaging within 67 days of receiving your order and we’ll give you a full refund, excluding any shipping charges.

You can send return products to a warehouse facility in your own country. Details are obtainable from the customer service department, and you can chat with customer services via live chat on the website.

Where To Buy PhenQ

PhenQ is available directly from the product website, and it is available to UK and to US customers.

One bottle of 60 capsules (1 month’s supply) costs £45.95.

You can buy two bottles and get one free (3 months supply) for £91.90.

Or buy three bottles and get two free (5 month’s supply) for £129.95. This option also comes with a free bottle of another supplement called Advana Cleanse.

Watchdog Verdict

Altogether, there are some good points about PhenQ. For example, this supplement has a money-back guarantee, and we like that the company seems to have a good reputation.

We’d like to know a bit more about a-Lacys Reset, the trademarked ingredient, but the other ingredients on the list look pretty decent.

PhenQ is definitely one of the better options available on the market.

38 comments on 'PhenQ'

  1. This definitely gave me jitters. Could not stick with it because felt dizzy and very unpleasant overall. I did have an additional charge on my purchase and they would not return my money, so not sure how reliable that is.

  2. I disagree with your assessment. I am v active and play lots of tennis. I was improving on PhenQ and tried Phentaslim after reading one of your recommendations (I purchased 4 bottles and abandoned after 1st bottle). Weight loss was significantly reversed and I have had to revert to PhenQ. No non-prescription weight loss aid is perfect and all require some discipline (exercise and reduced calories) to achieve benefits. My experience is that PhenQ’s appetite suppression is much better than Phentaslim.

  3. The PhenQ order has arrived.My question is Should I be taking PHEN Q (increased metabolism) combined with 1 daily Ramace tablet for slightly elevated blood pressure (137 / 80}

  4. Great article Jane! I think that it’s true to inform yourself about a fat reducer product, especially on side effects. At this purpose I’ve created a site called where you can find some fat reducer products and the reviews of people that have tested the products.
    Check it out:

  5. The PhenQ smells and “taste” kind of odd. Like white crayon Or something. And I haven’t seen any result. The only thing i seemed to get was a soar throat when eating them. That stopped as soon as I stopped using them. I

  6. Excellent site you’ve got here.. It’s hard to find
    quality writing like yours nowadays. I really appreciate people like you!
    Take care!!

  7. I don’t know whether it’s just me or if everyone else experiencing
    issues with your site. It seems like some of the written text in your content are running off the screen. Can someone
    else please comment and let me know if this is happening to them as well?
    This may be a issue with my web browser because I’ve had
    this happen before. Thanks

  8. I’ve been taking phen q for about a week now and have noticed my bloating is gone. I haven’t weighed in yet. Was wanting to at the one month Mark. Its really helped with appetite control and I’m a big coffee drinker so the caffine has never bothered me. In fact since taking them I stopped drinking coffee and started having caffeine headaches from the lack of it but the pills did help since it has a little in thing I have noticed is to make sure you eat when you take it. I got horribly sick when I took it on an empty stomach. Yes the pills taste gross…out it in your mouth and immediately drink and there is no problem. I actually sleep better at night. When my morning dose wears off I can feel it but it’s not too bad, at night though I sleep like the dead which is amazing because I could only sleep for 4 hours before now averaging at 7 hours straight a night.the cost was high but they had a promo code that took off 30 dollars when I bought them. I ordered two bottles of the pills and a bottle of detox. When I received it they sent a letter saying they were out of the detox and instead of my two bottles of pills when I opened my box there were 6 bottles of pills as an apology for not having the detox.

    1. It seems a bit odd for a company to send 4 bottles of pills for free in regards for an item that is not available, worth a couple of hundred dollars. A kind of warning sign are companys that compensate customers with products worth more then the thing u ordered. Could mean they know the pills are rubbish, and does not cost them anything, but from a customer point of view it seems very nice and they gain customers trust

  9. Total waste of money. Took for 1 month. No weight loss, no inch loss, chalky giant horse sized tablets that taste aweful and acidic in your mouth plus they are really expensive. I bought to help me curb my appitite but really didn’t help there either. I’m quite resilient to caffeine so was spared the side effects others have suffered.
    No money back from company – guarantee worthless.

  10. Waste of money. Tried Phenq for 3 weeks and did not lose any weight. Stopped taking the product. The money back guarantee, of course, is only if you bought the product for at least 60 days. DO NOT BUY.

  11. Tried for a month, no weight loss. Returned my product but they wouldn’t refund me my money. Got anxiety, headaches and my blood pressure went up. total waste of money. The web site is false and they are promoting false advertisement. Do not buy this product!!

  12. I am a man, initially weighing in at 107.5 kgs and 6 ft tall. I have been taking PhenQ for nearly 2 weeks. I don’t exercise other than walking on a Construction Site and drink plenty of water. Breakfast is a protein shake and lunch is a big salad with Tuna or last nights leftovers, with fruit in between. Dinner is normal including a beer or 2 some nights or wine. I have lost 2 kgs in 2 weeks and am happy so far. I will continue posting. Last weighed in at 105.3 kgs

  13. I have been taking PhenQ for second day. A lot of side effects. I feel really dizzy, headaches, my blood pressure is so high. I took only 1 pill a day. Half for each time but it still makes me sick. I think Im gonna just go for normal low carb diet. These pills should not be sold at all. I hope I am gonna get refund cause I paid 120 USD.

  14. I have been taking PhenQ for nearly 2wks, not lost any weight yet and been on a striked diet. Tablets are big and taste discusting if not swallowed on first attempt. Not had any side affects and haven’t surpressed my appetite so I wouldn’t personally recommend waste of money ?

    1. Julie, try eating whatever food for that particular meal, chew it up and before you swallow put the tablet in between. You are right, they taste awful. Keep trying, I’m on your side. Cheers

  15. I have been using this product for a month. No weight loss, extreme itchiness, mental confusion, headaches and heart palpitations. Very disappointing.

  16. I have been using this product for over a month and have experienced zero weight loss. I don’t think this product is worth the money

  17. No side effects
    Did give me energy and curves my appetite
    Almost finished my first bottle, and doing exercise and diet. NO weight loss yet
    Don’t know If I will finish my other two bottles

  18. First week diet was strict and was on 1100 calories and exercise every night 2nd week no weight loss at all with phenq 3rd still no weight loss sorry but this has acted as a diuretic causing headaches and anxiety total waste of money.

  19. On have been taking phenq for a week now and have definitely lost my appetite. Weigh in this morning and lost 5lbs. Down side can’t sleep and awful headache.

  20. Very good review. Lots of helpful indicator values. One tiny mistake I noticed is that you mentioned elevated calcium level as hypocalcaemia, which actually means decreased calc level. Other than that very helpful.

  21. I have been taking it for 1 week and the first thing I noticed was my loss of appetite. I am a man and have never paid any attention to this diet stuff I always just thought eat sensible exercise lots . As I have gotten older work responsibilities and hours have increased and time to exercise has decreased. This product works so far I have lost 4 ponds and have more energy.

  22. Thank you for posting this review on PhenQ. I’ve been using it for the past week and have experienced several of the side effects you mention. Nausea, constipation and anxiety being the most prevalent. I’m committed to my weight-loss and resolute to moving forward with the old-fashioned ways. Side note: this is my second week of being on a vegan diet and I’ve had the best weight-loss of my life and thought, PhenQ would assist me with this, but the side-effects are not worth it. I would caution anyone, who is interested in this product or any similar product for weight-loss. Best of luck!
