What ingredients do these supplements contain, and how are they effective at aiding weight loss? Let’s find out.
One of the main ingredients in instant knockout is caffeine. It can help to boost your energy levels and maintain your weight due to its actions at promoting thermogenesis.
Thermogenesis is the energy that is dissipated as your body produces heat, and more thermogenesis will cause you to burn more calories.
To cancel out the crash that can occur after having caffeine, Instant Knockout contains l-theanine. This helps to stop the jitters setting in and has been found to encourage relaxation. It helps ensure you are well rested, meaning you have more energy the next day to, for example, work out.
Instant Knockout also contains vitamin D3, which has been found to be great for protecting bones, particularly of those who frequently exercise. Studies have also found that it can help you to lose weight due to its links to Body Mass Index.
The main active ingredient in Hydroxycut is C. canephora robusta extract, also known as Robusta coffee.
These premium coffee beans aren’t roasted, and therefore contain a lot of chlorogenic acid, which has been found to promote weight loss.
The hydroxycut website speaks about a study that found taking Robusta coffee for 60 days can lead to an average weight loss of 10.95lbs.
Hydroxycut also contains thiamine, which supports body cells in converting carbohydrates to energy. It helps to keep your metabolism functioning properly, so the stored energy in the food you eat is used up. This all aids in weight loss.
Another ingredient in Hydroxycut is folic acid. This ensures the proper metabolism of protein, to enable your body to keep a sustained insulin level. A stable insulin level helps your body to burn fat instead of storing it, which therefore increases weight loss.
There is no winner when it comes to ingredients.
Both supplements contain completely natural ingredients that have been shown to aid in weight loss.

Safety and Potential Side Effects
Are these weight loss supplements safe? Let’s learn about their side effects and how they compare.
Instant Knockout is not FDA approved and therefore you might experience some side effects. However, the FDA does regulate the product.
Some side effects people have reported include troubles sleeping, which could be due to the natural stimulants in the supplement. People have also said they had an upset stomach, nausea, vomiting, and headaches.
It is advised to take Instant Knockout before eating, and to reduce your daily dosage if you do experience any side effects.
Like Instant Knockout, Hydroxycut is also not FDA approved. In fact, back in 2009 the FDA released a consumer warning on all of the Hydroxycut supplements, and the products were recalled by the company.
Whilst the issues were said to be resolved, since 2009 there have been cases of people experiencing liver failure and other serious issues which have been linked to Hydroxycut.
In 2011, there was a case of someone suffering from ischemic colitis, a condition where there is reduced blood flow to the colon, because of taking Hydroxycut.
Some of the more general side effects people have experienced include nausea, jitteriness, diarrhoea, and troubles sleeping.
Instant Knockdown is the winner in this area.
Whilst neither product is FDA approved, Hydroxycut has been linked to some very severe illnesses in the past, whereas the side effects of Instant Knockout appear to be milder.
Let’s see what results customers have experienced from using these weight loss supplements.
There were numerous positive reviews on Instant Knockout, with people saying it helped them to see changes in their body after finishing one bottle.
There were also many reviews saying how it helped to boost their energy levels.
One customer reported losing about 2kg every month by taking Instant Knockout.
However, there were quite a lot of negative reviews of people saying they didn’t see any changes from using the supplement.
One of the main comments from customers was that Hydroxycut is great for boosting energy. With the caffeine it contains, people said it stopped them from feeling lethargic and enabled them to feel more motivated at the gym.
Some customers also said it curbed their appetite, helping them to consume fewer calories throughout the day.
However, there were some reports of customers saying it didn’t work for them, and some even advised against this product for people who have any heart issues.
Some people said this supplement was like a laxative pill and not very pleasant, with others saying they had major headaches and felt very nauseous after taking it.
This is a tough one to call, but Instant Knockout just takes the win.
Whilst there wasn’t a wealth of reviews on Instant Knockout, and Hydroxycut actually had more positive reviews than Instant Knockout, the negative reviews of Hydroxycut are what weighs it down due to people experiencing many negative side effects.
Manufacturing and Brand
A good indicator of how good a supplement will be is how reliable and trustworthy their manufacturers are.
Instant Knockout is manufactured by Roar Ambition, who aim to create the best fat burner possible using natural ingredients that have scientific evidence backing their ability to lose fat and gain muscle.
Roar Ambition makes Instant Knockout in the USA and the UK, in facilities that follow Goods Management Practice. Also, whilst the product itself is not FDA approved, the facilities in which it is made are.
Furthermore, Roar Ambition assures that they use only top quality, completely natural ingredients in their products.
Hydroxycut is manufactured by Muscletech, who are based in New York and Canada.
The company undergoes thorough research and development for their products to ensure they only use effective, top-quality ingredients.
However, there is no information about whether the manufacturing facilities are GMP certified.
Furthermore, as mentioned earlier, the statement released by the FDA telling people not to use the supplement, and the product recall that occurred, doesn’t put huge confidence in the manufacturers.
Instant Knockout is the clear winner here.
Its manufacturing facilities are FDA and GMP approved, whereas those of Hydroxycut are not.
Price and Value for Money
How much are these weight loss supplements? Which is cheaper? Let’s look.
For one bottle, which is a month’s supply, of Instant Knockout it will cost you $59.00.
If you subscribe, meaning you automatically get sent a new bottle every month, then you will save 10% on every bottle.
Furthermore, if you buy 3 bottles in one order, then you get an extra bottle for free!
Instant Knockout has a 14-day return policy for people in the UK and 30-day return policy for people in the USA.
There are a few different versions of Hydroxycut you can get, including gummies and drink mix.
Each product is about $19.99, which will last you about 15 days if you follow the recommended dosage. So, for a month’s supply you will be paying about $40.
Hydroxycut offers free shipping for orders above $19.99, and they have a 30-day return policy.
This is a very close call, however Hydroxycut just about wins.
Hydroxycut takes the lead with how a one month’s supply costs about $20 less than Instant Knockout.
However, the fact that the Hydroxycut only supplies bottles for 15 days’ worth of supplement means that it could potentially be more hassle having to constantly reorder bottles and having to find a place to store them all.
Instant Knockout has the advantage of each bottle being a full month’s supply, and the fact they offer a subscription service is great for people who don’t want the hassle of remembering to reorder the supplement every month.

The issues Hydroxycut have had in the past with an FDA warning on their supplements and a product recall is a major concern and makes us doubt the safety of the supplement.
Whilst Hydroxycut is cheaper, the subscription service offered by Instant Knockout can be very beneficial, and you get a full month’s supply in every bottle compared to only 15 days’ worth in a bottle of Hydroxycut.
Instant Knockout has had great reviews from customers, and whilst it is not FDA approved, the FDA do regulate the product which gives confidence in the supplement’s effectiveness and safety.
