PhenQ Review - 9 Things You Need to Know

PhenQ says it’s got the power of multiple weight loss supplements and that users will naturally shed pounds. When we looked for evidence supporting these bold claims, we found solid research on some of its ingredients.

However, when it came to its formula, we came up short. Our research team found that PhenQ only contains 25mg of its main ingredient, while science says you need 1800mg per day. In addition to that, there were some lukewarm online reviews.

We dug up dirt on PhenQ, researched its ingredients, compared them to clinical trials, and read user remarks. Here, we summed up all the information to give you the facts on these diet pills.

PhenQ can be purchased through their Official Site.

PhenQ Video Review


What Is PhenQ?

PhenQ isn’t just another dietary supplement. It stands out as an advanced formula crafted to optimize weight loss through multiple avenues, ensuring that users get the best results. Through a combination of natural ingredients, PhenQ addresses the key challenges that individuals face on their weight loss journey.

The company claims that PhenQ works by:

1. Suppressing Appetite: It effectively diminishes the urge to snack frequently, with a significant reduction in sugar and carb cravings.
2. Boosting Metabolism: PhenQ elevates the body’s metabolic activities, ensuring that fat is burned more efficiently.
3. Providing Natural Energy: By transforming stored fat into fuel, it guarantees that users remain vibrant and active throughout the day.
4. Accelerating Fat Breakdown: It doesn’t just stop at boosting metabolism. PhenQ goes further to break down fat at an enhanced rate.
5. Hindering Fat Accumulation: With PhenQ, the body becomes less inclined to store excess fat, ensuring that gains made in weight loss are maintained.

The trio of primary ingredients, which includes ALA, peppers, and a globally-renowned stimulant, synergizes to deliver these impressive results. Furthermore, PhenQ’s ability to uplift the user’s mood acts as an added bonus. This means that motivation levels remain elevated, making the weight loss journey smoother and more enjoyable.

For adults over 18 years who are looking to shed some extra pounds, PhenQ proves to be a reliable partner. Whether you’re pushing yourself in the gym or streamlining your diet, PhenQ enhances your efforts. Its proficiency in regulating sugar and carbohydrate cravings makes it particularly beneficial for those battling eating disorders.

  • Obesity Reviews – “Alpha-lipoic acid treatment showed small, yet significant short-term weight loss compared with placebo.”
  • Appetite – A chemical found in Capsimax is capsaicinoids. According to the journal, “daily consumption of capsaicinoids may contribute to weight management through reductions in energy intake.”
  • European Journal of Clinical Nutrition –“Consumption of caffeinated beverages might support weight loss maintenance.”

PhenQ Ingredients

PhenQ ingredients include:

  • Calcium 230mg
  • Chromium 80mcg
  • L-Carnitine fumarate 150mg
  • Caffeine anhydrous 100mg
  • Nopal cactus fiber 20mg
  • Capsimax Plus Blend (Caffeine anhydrous, capsicum fruit extract, niacin, black pepper fruit extract-50%piperine) 50mg
  • α-LACYS RESET (combination of alpha-lipoic acid and L-cysteine) 25mg

Caffeine Anhydrous

According to the Journal of Basic Clinical Physiology and Pharmacology, “Caffeine improves weight maintenance through thermogenesis, fat oxidation, and EI [energy intake].” So, caffeine increases the number of calories the body burns and helps reduce the number of calories consumed—a win-win situation.

A 2019 review of research by the Cochrane Database came up with the same results. “Overall, the current meta-analysis demonstrated that caffeine intake might promote weight, BMI, and body fat reduction.”

A-Lacys Reset

A-Lacys Reset is a patented formula containing alpha-lipoic acid and cysteine. Alpha-lipoic acid is an antioxidant found in foods, including spinach, potatoes, and broccoli.

In a study involving rodents and humans, the International Journal of Obesity concluded, “l-cysteine reduced hunger in humans and decreased food intake in rats and obese mice.”


According to the journal Comprehensive Reviews in Food Science and Food Safetypiperine has been shown to “enhance the bioavailability of nutritional and botanical compounds.”

Advances in Experimental Medicine and Biology also share that piperine may have other health benefits, including anti-inflammatory effects and defense against some chronic health conditions.

Chromium Picolinate

Chromium is a trace mineral and is involved in “the metabolism and storage of carbohydrate, fat, and protein in the body,” says the NIH Office of Dietary Supplements.

At doses of 400mcg/day for at least 12 weeks, “chromium supplementation was associated with some improvements in body composition in subjects with obesity/overweight,” according to Clinical Obesity.

Bottom Line

What Users Are Saying

“So far so good, been taking for 2 weeks now, down 4 pounds. I’m not snacking after dinner, I’m cutting down on sugar intake- drinking more water and do 4-5 gym classes a week.”

“I bought 3 bottles in June 2023. Took 2/day for 2 months and saw 0 results; as far as weight loss. I have a moderate exercise routine (1 hour) 3-4 times a week. I bought these pills to move past my plateau to lose a few additional pounds. I could not return the product under the money- back guarantee because it was past the 67 days when I emptied the second bottle. I ordered the night burners but did not take them at 4 pills/ night. Don’t waste your money!”

“Taking the day and pm pills for over 6 weeks now have not noticed any weight loss at all a slight decrease in cravings but not much I have been eating healthy for. Few months now I have an Underdesk peddling machine and exercise bands at my desk that I use daily I eat some boneless skinless baked chicken breast or thighs for breakfast and a salad for lunch I try to stop there sometimes if I am Still hungry at dinner time I will have a couple bites of chicken and that’s it. I drink plenty of water my calorie intake is very low but my body does not lose any lbs I have been at The same weight since I started no weight gain or loss just staying at the same weight pills have not helped me I am so discouraged I will finish the bottles I still have and most likely not buy anymore I am trying to see if my body just needs to get used to the pills I know it’s harder to lose than to gain the weight so I’m still hanging in there hoping for some lbs to fall off.”

  • Dissapointing .. no results after 1.5 bottles...
    Andi (Verified Purchase)

    I am into my second bottle of PhenQ…. no change whatso ever.(
    I am active and Consume very little carbs, no meat, or milk. My energy levels have not changed, I have noticed that my calorie general burn per day has increased slightly although I have just smashed my ribs so could be a healing side effect.
    Really Disappointed so far, I realise everyone is different but I am half way through my 3 bottles .

  • Not effective
    Julie Lightfoot

    I have been taking PhenQ for 3 weeks but haven’t lost any weight at all, even though I have been exercising. I have no side effects, and feel no different, I’m really disappointed…

  • 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 Purchase)

    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 Purchase)

    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 Purchase)

    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

        • Dr. KnowsBetter

          It’s “cos” she is not used to caffeine.
          Denise… Don’t pay attention to comments like this as this level of ignorance is actually dangerous. If you are uncomfortable due to the increased heart rate, reduce or stop taking it. By NO MEANS should you exercise in this state.

    • Gada

      That’s what happened to me when I talk with them online they said no problem with that product

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

    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 Purchase)

    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.

  • No results after three weeks
    Vicente Sánchez (Verified Purchase)

    I have been taking two pills a day for three weeks and nothing.

    • Steph guest

      Same here, I exercise a lot and eat right and not 1 gram lost. Always hungry too, really disappointed

  • Akesa (Verified Purchase)

    All the comments are like 1 day, 2 days, 1 week. Blah blah blah. Surely you don’t expect it to work in that time, do you? If you have no ounce of patience, then perhaps you shouldn’t use it. I lost 11kgs in 1.5 months in Phenq. Get out and walk, exercise. Yes, I had nausea and headaches, but it only only lasted up to 2 weeks and then was gone.

    • Karmela

      Like ur comment girl I’m looking forward And excited to use the product u hope it will arrives as soon as possible. Patience patience with the help of phenq there will be a new me

    • amanda jane cooper

      i have just ordered my 1st 3 bottles i am a bit sceptical thank you for your review i just hope i do as well as you and your family as money is short and i am worried i have just wasted a lot of it buying this product

  • Alecia (Verified Purchase)

    Ok, so I started taking phenq because of my sister. She showed thirty pounds lost in one month taking it. I started to try it, at first I drank coffee in the morning and took a phenq. Yes, I felt jittery, anxious, and I also forgot to eat durring the day, from being too busy. It gave me extreme energy like crazy. So, this was from two days taking it, which I took it completely wrong, but I all ready noticed water weight gone. Ok, so I cut back from taking two a day to only one a day no coffee at all. I drank lots of water ate breakfast and lunch. After a week I lost five pounds. I bumped my phenq up to two pills a day. I ate breakfast and then took a pill, ate lunch and then took another pill, and this is at 6am for first pill and 11am for lunch for the 2nd pill. I started to notice inches shrinking around my stomach, arms, butt, and thighs. I turned my dad onto this and he took it just like me and started dropping inches also. Now we didn’t notice pounds going down, but clothes started to fit again going from a size 14-16 to a size 10 is amazing results for me. My sister went from size 22 to a size 16-18. She is now having another baby, so she had to discontinue taking phenq, but she will continue taking phenq once she has the baby. My dad went from a size 44 to a 38 he hasn’t taken it long enough only 3 weeks, but he hasn’t seen that size in a long time. Im continuing to take phenq and my waist is 30 and my hips are 39 inches which my waist was 35 and hips were 45 so yes phenq has helped me a lot. Remember to drink lots of water, eat a good meal before taking it, don’t drink any coffee , and you won’t have your jitterieness, headaches, but you will have crazy amount of energy, and you will want to move around more so than ever. Good luck!!!
