1.1. PhenQ

Those who want to shed pounds and tone up can use the fat-burner supplement PhenQ. It’s made up of all-natural ingredients that a Wolfson Brands team of experts hand-picked and created into soft capsules.

Key primary advantages of PhenQ include aiding in fat burning, curbing fat buildup, reducing appetite, boosting energy, and regulating mood. To achieve them all at once, PhenQ stimulates the fat-blasting thermogenesis in your body.

Furthermore, there is a strong indication of customer feedback for this product. More than 400 people reviewed it online, and more than half gave it five stars.

1.2. Instant Knockout

A similar fat-burning supplement called Instant Knockout uses the well-known equation “faster metabolism = less fat storage.” Indeed, its natural ingredients are designed to speed up metabolism and promote fat loss.

As far as we can tell from its official website, gymnastic athletes are advised to use the product. Greg Jackson, an MMA coach, emphasizes the product’s advantages in assisting with lean and ripped bodybuilding.

Having said that, most people can benefit from Instant Knockout. To achieve overall better health, everyone should generally improve their metabolism and fat levels.

In summary, both supplements support fat loss. However, while PhenQ stimulates thermogenesis, Instant Knockout improves metabolism to achieve that goal.

2.1. PhenQ

PhenQ is all about kickstarting the natural mechanism of your thermogenesis to burn fat. Therefore, the ingredients must have been chosen to serve that goal. Let’s see if it’s true.

  • Calcium Carbonate: The body’s lipolysis and thermogenesis can be slightly elevated by calcium [1]. This could therefore raise metabolism, encouraging our bodies to start burning fat.
  • Capsicum Extract: This substance has been proven to positively affect obesity. It reduces excess energy in fat cells and increases thermogenesis.
  • Piperine Extract: This compound is extracted from Black Pepper. According to a study, it can prevent the body from producing new fat cells [2] and may be used to treat obesity.
  • A-Lacy Reset: a-Lacys Reset is a clever pairing of alpha-lipoic acid and cystine. The effectiveness of Alpha-lipoic acid has been recognized in obesity treatment [3].
  • L-Carnitine Tartrate: This amino acid occurs naturally and helps people feel more energized by delivering fatty acids deep inside the mitochondria, where they can be burned and used as fuel to power the body.
  • Nopal: Because nopal has high fiber content, it helps your body break down and excrete fat. That controls your appetite and helps you lose weight.
  • Chromium Picolinate: Chromium can increase lean body mass and reduce body fat, according to various studies. However, this substance is insignificant in controlling weight loss [4]. 
  • Caffeine Anhydrous: Caffeine consumption may help people lose weight, lower their BMI, and burn more body fat, per a meta-analysis [5].

2.2. Instant Knockout

Here are Instant Knockout ingredients:

  • Vitamin B6: Weight loss specialists have discovered that this vitamin is very advantageous for various bodily processes required for weight loss. It breaks down proteins, carbohydrates, and fats.
  • Vitamin B12: A higher intake of vitamin B12 lowers the risk of obesity [6] and weight gain. Vitamin B12 also prevents megaloblastic anemia, a blood disorder causing bad mood.
  • Zinc: This chemical is another efficient therapy for fat-burning. Zinc deficiency is responsible for many problems related to instant weight gain.
  • GTF Chromium: This substance regulates the activity of insulin and aids in metabolism. To some extent, it can also support weight loss but slightly.
  • Green Tea Extract: Green tea includes many antioxidants and a lighter amount of caffeine. When these two compounds enter the body, it burns calories fast [7].
  • Green Coffee Extract: A study has shown that people can attain weight loss with green coffee extract [8]. However, no studies have been found to back its robust effectiveness in burning fat.
  • Cayenne Powder: Cayenne powder is a spicy food that can help boost metabolism and burn calories. Besides, it makes you feel less craving unhealthy food.
  • Glucomannan: This substance contains a lot of fibers. When it is absorbed into the body, it soaks up in the digestive tract, taking up space in your stomach and promoting longer fullness.
  • Caffeine Anhydrous: A consistent caffeine intake can promote body fat reduction and athletic performance.
  • Black Pepper Extract: As explained above, this ingredient aids in prohibiting the production of fat cells. It’s spicy food, so it may stimulate the metabolism to burn fat and calories.

Suggested Dosage


3.1. PhenQ

The recommended dosage for PhenQ is one pill twice per day. A bottle contains 60 capsules, so you should have a one-month supply with just one bottle.

Take one before your breakfast in the morning and the next one with your lunch daily. Additionally, drink a full glass of water with the capsule to gain the best result. Also, since PhenQ includes caffeine, don’t take it after 3 pm or else you can barely sleep at night.

3.2. Instant Knockout

Instant Knockout requires taking more capsules than PhenQ. You must take one pill four times per day to have the best result with this fat burner.

Take one in the morning, one before lunch, one in the mid-afternoon, and another one with the evening meal.

This supplement contains caffeine; therefore, you may experience difficulty going to sleep at night. The dosage is also cumbersome with 4-time taking per day for a bottle of 120 capsules. That means you also have a one-month supply with one bottle.


Side Effects

Side Effects

PhenQ Vs Instant Knockout: Side Effects

4.1. PhenQ

PhenQ is a safe fat burner supplement, meaning it shouldn’t generate any severe side effects. However, whatever supplement you will take, it’s best to seek medical advice on it or do your research about the ingredients.

Because PhenQ also provides Nopal, you may experience at least any of these minor side effects: diarrhea, headaches, and bloating.

That said, the overall ingredients in PhenQ make this supplement usable for everyone. It burns fat effectively in a good timely manner without causing severe adverse reactions.

4.2. Instant Knockout

Like PhenQ, Instant Knockout provides all-natural ingredients that are backed by science to be safe. Needless to say, humans need them to have better health. However, 300mg of caffeine in its formula may be a serious concern for most people.

Typically, Instant Knockout is designed rather for athletes and bodybuilders. That means they would need high energy levels from their caffeine consumption to focus on heavy physical activities. If you’re not one of them, you may experience anxiety, stomach upset, insomnia, and slight digestive issues.


How Much They Cost
