To lose weight, you have to change your dietary routine and daily habits. For some people, that might not be enough to reach their long-term goals. 

This is where certain weight loss supplements come into play. A fat-burning supplement usually claims to block fat production and boost your overall progress on a healthy diet. While this might seem too good to be true, many dietary capsules can improve your weight loss journey over time. 

PhenQ and Instant Knockout are prime examples of these supplements, but which one should you choose? Keep reading to find out.

Learn More

PhenQ is designed to support your body in burning stubborn fat. This popular fat-burner supplement is made of natural ingredients, like capsicum and nopal, to help you lose weight. You can also take it to reduce those dreaded hunger cravings on a diet.

Some benefits of PhenQ include less fat production, reduced hunger, and improved energy levels. The creators of these weight loss pills state that exercise and healthy eating are necessary for them to work. 

All you need to do is take one capsule with breakfast and another with lunch. You shouldn’t take any in the evening since it contains caffeine and might disrupt your sleep.

Instant Knockout Cut is a fat-burner supplement that can help people lose body fat and gain lean muscle. This product focuses on boosting energy levels, improving metabolism, and preventing excess body fat. 

The supplement was originally made for MMA fighters and other professional fighters, but anyone can use it. The creators believe that regular exercise can also enhance your results over time, so it’s worth going for walks or long-distance runs

You have to take 4 capsules a day; one in the morning before breakfast, one 30 minutes before eating lunch, one in mid-afternoon, and the final one 30 minutes before your last meal.

Ingredients

Both of the supplements have a range of ingredients that can support weight loss, fuel your muscles, and boost your overall mood. It’s important to study the label of each supplement to ensure it suits your preferences. 

PhenQ ingredients 

  • Capsicum extract: Research suggests that capsicum can help decrease your body fat percentage by boosting your metabolism. A fast metabolic rate means you’re constantly burning calories. 
  • L-carnitine fumarate: This chemical may increase how many calories you burn through exercise. Going for more regular walks or runs during the day could boost your weight loss results. 
  • Caffeine anhydrous: With this being the same form of caffeine in Instant Knockout, it can keep you focused and improve your exercise performance. 
  • Nopal: Natural cactus fiber can reduce your appetite on a healthy diet. The high fiber content slows down digestion in the stomach, which stops you from eating too many calories. 
  • Chromium picolinate: This form of chromium can increase your resting energy expenditure, meaning you burn more calories at rest. Over time, you will lose excess fat, especially if you exercise regularly. 
  • Calcium carbonate: A chemical compound that supports muscle growth and bone strength. You should choose a supplement containing this ingredient if you want to stay strong while losing weight. 
  • Lacys reset: The patented formula comprises alpha-lipoic acid, magnesium, and cysteine. These ingredients support weight loss, boost your energy, and curb your appetite. 
  • Magnesium stearate: This is a type of salt derived from stearic acid. It can only improve the quality and consistency of common weight loss pills. 
  • Niacin powder: An ingredient that may reduce fat cells by boosting your metabolic rate and improving energy production. However, it may cause more side effects in some people. 
  • Piperine extract: Studies have proven that piperine reduces LDL “bad” cholesterol and triglycerides in your body

Instant Knockout Cut ingredients 

  • Black pepper extract: This ingredient contains piperine, a compound that encourages your metabolism to burn more calories. It can also lower the number of lipids in your bloodstream. 
  • Green tea extract: Evidence suggests that green tea increases thermogenesis to stimulate metabolism. Since it is also high in antioxidants, it will support heart and brain health. 
  • Cayenne powder: Natural cayenne may reduce your hunger cravings because it helps your metabolism to use more energy from body fat. In turn, you will consume fewer calories and lose weight. 
  • Vitamin B6: This vitamin encourages your body to absorb more amino acids. These acids fuel muscle growth and ensure a speedy recovery after intense weight training. 
  • Caffeine anhydrous: Any type of caffeine increases energy, which can boost your exercise performance. The increased alertness keeps you focused on losing weight and building muscle. 
  • Glucomannan: Another ingredient that curbs your appetite on a diet. It slows down digestion by adding bulk to your stools. This can also help treat constipation and stomach cramps. 
  • Vitamin D3: Studies prove that vitamin D3 reduces the accumulation of new fat cells in the body. This could prevent weight gain and help you burn more stubborn body fat over time. 
  • Vitamin B12: This vitamin supports the production of red blood cells, which naturally pumps your muscles with oxygen. You need B12 to keep your muscles strong after recovery. 

How Do These Products Work? 

PhenQ is a fat-burner supplement that can help you lose weight faster. By taking the capsules, you’re essentially fueling your body with powerful compounds. 

For example, the lacys reset blend uses alpha-lipoic acid, magnesium, and cysteine to promote fat loss over time. A study found that those who consumed alpha-lipoic acid lost 1.27 kilograms or around 2.8 pounds more compared to those who didn’t take it. This shows that PhenQ has the potential to reduce belly fat

Instant Knockout Cut focuses on weight loss and muscle growth. Ingredients like black pepper and vitamin B6 may slow down fat production while fueling muscle recovery. Research suggests that black pepper could reduce common side effects of delayed onset muscle soreness (DOMS).

Other components like caffeine and vitamin B12 give you energy. You can lift weights at the gym without feeling fatigued or weak. This supplement allows you to lose fat and maintain muscle on your fitness journey. 

What Is the Key Difference Between PhenQ and Instant Knockout? 

A key difference between these fat burners is that PhenQ was created for weight loss, while Instant Knockout Cut is more suitable for muscle growth

PhenQ contains several fat-burning ingredients, like chromium picolinate and the Lacys reset blend, that focus on reducing fat cells. On their official website, they state that this supplement supports natural energy and eliminates stored body fat. 

On the other hand, Instant Knockout Cut drives muscle growth. Vitamin B6 and B12 feed your muscles energy to help them recover after strength training. People who want to tone their bodies may choose this supplement over PhenQ. 

Possible Side Effects of PhenQ and Instant Knockout

Both of these fat-burner supplements may cause side effects like:

  • Nausea
  • Bloating
  • Headaches
  • Stomach cramps

Due to the caffeine content, you might also experience anxiety symptoms, insomnia, and a faster heart rate if you’re sensitive to stimulants. 

Side effects are not common with these fat burners, but it’s important to stop taking them if you don’t feel well. Also, talk to a medical professional if you notice rare symptoms like a rash or shortness of breath. 

Pricing

At the time of writing this review, these are the prices of the two weight loss supplements:

  • PhenQ: $69.99 for 1 bottle, which contains 60 pills
  • Instant Knockout Cut: $65 for a 1-month supply, which is a bottle of 120 capsules

What’s great is that both PhenQ and Instant Knockout offer bundles and deals when buying multiple products.

How We Tested the Products  

When examining the two products, we focused on the quality, effectiveness, price, and brand reputation of each supplement.

Quality 

We believe that PhenQ and Instant Knockout Cut are high-quality supplements that contain natural and safe ingredients. They meet pharmaceutical standards and do not have hidden preservatives that could damage your health.

Just be aware that PhenQ has third-party testing, and Instant Knockout does not. 

Effectiveness 

PhenQ and Instant Knockout Cut are effective when paired with a healthy routine. These fat burners only work if you exercise and eat at a calorie deficit. Everyone has unique results, so you might notice more physical differences compared to other people. 

Price 

Our team understands that some people have a budget. Buying an expensive weight loss supplement isn’t very sustainable. PhenQ and Instant Knockout have a hefty price tag when it comes to the dietary supplement market.

Instant Knockout Cut is $65, and PhenQ is $69.99. You should choose a fat-burner pill that suits your specific needs.  

Brand reputation 

We studied each brand to learn more about its mission. PhenQ focuses on a “well-researched formula” to help customers meet their long-term goals. Instant Knockout understands that “nutrition and weight management” are factors of success. Overall, both brands are transparent and reputable. 

FAQs

Are Instant Knockout and PhenQ FDA-approved?

No, these fat burners have not been approved by the FDA. This organization cannot provide approval to weight loss supplements because they don’t have the authority to study a product’s safety and effectiveness.

Where can you buy PhenQ?

You can purchase it on the manufacturer’s website.

Is Instant Knockout safe to use?

Yes, Instant Knockout is a safe dietary supplement. It contains natural ingredients that won’t harm your body during weight loss and muscle growth. If you experience any side effects, stop taking the supplement immediately and speak to a medical professional.

Is PhenQ safe to use?

PhenQ is a safe dietary supplement that shouldn’t cause any side effects. The manufacturer has stated that it contains natural ingredients to boost the fat-burning process. However, if you do experience side effects, stop taking the supplement.

A Word From Our Nutritionist

It’s important to remember that a fat-burner pill won’t directly burn body fat, so you have to get regular exercise, follow a low-calorie diet, and drink plenty of water to see real results.

For those who are seeking muscle growth, consume adequate amounts of protein throughout the day. Aim to get 100 grams of protein daily to burn fat and grow lean muscle. You can also take other supplements that contain creatine, beta-alanine, calcium, magnesium, and vitamin B3.

If you have a medical condition or are currently pregnant, speak to a medical professional before taking new weight loss supplements.

The final verdict: PhenQ or Instant Knockout?

We believe PhenQ is a more effective weight loss supplement simply because it is specifically meant for weight loss, while Instant Knockout is designed to tone and build muscle.

Whichever supplement you choose, keep in mind that to achieve your goals, you have to follow a low-calorie diet, exercise regularly, and drink plenty of water.
