Some people may be cautious about dietary supplements, especially if they've had mixed experiences with products from the same company.

As a fitness coach, I've seen many clients benefit from supplements like PhenQ and Phen24. Curious about their effectiveness, I've consulted with nutritionists and analyzed their promised results.

So, what benefits do they offer, and can they help you achieve your weight loss goals?

Keep reading and find out which dietary supplement is best tailored for your lifestyle.

What Are PhenQ and Phen24?

PhenQ and Phen24 are fat burner supplements that aim to lower bodyweight through thermogenesis. ​PhenQ works by delivering five benefits that maximize fat-burning. It reduces stored body fat, suppresses the appetite, stops fat production, increases energy, and boosts mental focus. On the other hand, Phen24 speeds up your metabolism and activates thermogenesis in your body, even while you're asleep.

Phen24 night pills are taken before your last meal.

​They claim it can help you with fat loss every hour. It has a similar composition to other nighttime fat burners.


PhenQ and Phen24: Similarities

PhenQ bottle

Both PhenQ and Phen24 serve as alternatives to Phentermine, offering similar benefits according to my research.

In my research and from feedback within our team, we consistently found that when used correctly, they rarely cause any side effects. This aligns with the occasional symptoms, such as nausea, upset stomach, or headaches, that I had initially come across.

However, take note that PhenQ may not be a good choice if you're breastfeeding or pregnant.

Let’s discuss how these fat burners work to help you lose weight.

Suppresses Appetite

Both formulas contain natural fat-burning ingredients that can suppress your appetite, decreasing your food intake in general. It can help you eat appropriate serving sizes and reduce those late snacks, which helps dieting and achieve a caloric deficit. Phen24 in particular contains L-phenylalanine, which reduces ghrelin, a hunger hormone.

Meanwhile, PhenQ has the Nopal cactus fiber. It binds to dietary fat, reducing absorption, and helping reduce your caloric intake daily. It applies whether you're trying to achieve ketosis or undertaking vegetarians diet.

PhenQ and the Phen24 formula both have chromium picolinate, an essential mineral for lipid metabolisms.

A double-blind study from the Journal of Psychiatric Practice involving 113 patients showed that chromium picolinate was effective in reducing cravings and improving focus [1].

Increases Metabolism

Increases Metabolism

The natural ingredients in both PhenQ and Phen24 can boost your metabolism, which may lead to an increase in body heat. More body heat equals more calories burned, which helps obese people shred more fat.

PhenQ and the Phen24 day formula both have several ingredients to support the metabolism, including capsicum, cayenne pepper, and caffeine. These help with weight reduction and weight management through fat metabolism. With nutrients like vitamin B3, you will have a more balanced diet as a result.

The night Phen24 weight loss pills affect your metabolism differently, and I’ll cover that in the next section.

Boosts Energy Levels

Any good diet pills will also give you an increase in energy levels. It would be best if you had more energy to burn through calories and aid your weight loss journey.

Both products have green tea extract to support energy and help your body get through tough workouts. In a randomized, double-blind, placebo-controlled study, six overweight men were given 300 mg EGCG/d for two days and were found to have lost weight [2].

However, note that caffeine in the supplements could make you feel jittery or unable to sleep at night, especially when you're sensitive to this ingredient.

If you're unsure whether you have caffeine sensitivity, ask your doctor for advice. It applies whether you're one of the vegans or carnivores.

"Green tea has many health benefits from helping you burn more fat, to breaking down harmful plaques in your blood vessels and even potentially staving off diseases such as dementia." -Dr. Michael Mosely

Increases Metabolic Rate

Both supplements can help you with losing weight by increasing satiety. As mentioned earlier, dietary fat burner supplements increase your metabolic rate and reduce hunger cravings.

They aren’t magic pills, though. You still have to put in the work to burn fat tissue. It would be best if you have a calorie-reduced diet, exercise, and get plenty of rest to lose those extra pounds.

Weight loss pills may give you that extra push to lose weight faster. But it’s meant to supplement your diet, not replace it. It means you need to get most of your essential nutrient needs from red meats and other food items. These include calcium carbonate, iodine, copper, niacin, amino acid, and zinc.

After all, iodine could help with thyroid function while calcium supports a healthy heart. These human health benefits are too good to pass up.

PhenQ and Phen24: Differences

The main difference between PhenQ and Phen24 is that the former is designed for people looking to consume fewer calories to avoid weight gain while maintaining muscle mass. On the other hand, Phen24 is for individuals looking to boost their metabolism, even during the night.

We discuss it in more detail below.


As I mentioned earlier, the evening Phen24 pills work differently than the day version and PhenQ. Your metabolism goes into a resting mode while you sleep. The nightly Phen24 pills adjust to that.

Like other quality dietary supplements, both products help support your metabolic rate, but not in a way that increases energy. Instead, they increase calmness, making it easier to sleep, get rest, and maintain blood sugar levels [3].


PhenQ contains a unique formula called a-Lacys Reset. It’s a scientifically-proven formula that helps to increase your metabolic rate and burn calories faster.

It has several ingredients that Phen24 doesn’t have in its formula, including nopal, l-carnitine, and capsimax powder. The capsimax blend has black pepper, caffeine, and niacin, which also contains piperine that enhances fat cell reduction.

Based on industry trends and observations, it's evident that PhenQ has a more established presence than Phen24. It has garnered a substantial and loyal user base. So, if you prioritize products with a proven track record, PhenQ would be suitable.

Over the years, numerous clients have included PhenQ in their daily routines. That's Sarah's case, in particular. She gained a significant energy boost and told me how her once-persistent cravings seemed just to fade away, all thanks to PhenQ.

People also report in these reviews that they had no side effects and had a great work out performance overall.

Do PhenQ and Phen24 Have Side Effects?

Yes, PhenQ and Phen24 may have side effects such as nausea, nervousness, upset stomach, and an elevated heart rate. These events can vary among individuals.

PhenQ vs Phen24: Which Is Better For Weight Loss?

PhenQ and the day Phen24 supplements help reduce your appetite, increase your metabolic rate, boost energy, and ultimately support weight loss.

The big difference is the night Phen24 supplements. Having that extra work while you sleep is a unique benefit that I haven’t seen anywhere else.

Although some users find it a hassle to take 2 pills, and because of this, Phen24 ends up pricier, too.

PhenQ, however, contains the a-Lacys reset, which is quite an interesting blend of scientifically proven weight loss and fat burning ingredients.

I don’t think you can go wrong with PhenQ or Phen24. But if you compare them head to head, PhenQ may give you better results without taking a separate pill in the morning and another at night.

If you try out either one, let us know which one you think is best! We would love to learn and support your weight loss goals and results.
