Who is Instant Knockout Complete For?

The meal replacement shake was originally designed for fighting sports such as boxing or MMA. Both sports rely on gaining and losing weight before fights, and a meal replacement shake is an ideal product for that.

But Instant Knockout Complete can suit just about anyone. It uses a plant-based approach to ensure that the product is vegan friendly and doesn’t contain any ingredients that are in any way dangerous or unsafe.

If you are looking to lose weight, maintain your current weight easily, or even gain weight, then Instant Knockout Complete is the ideal supplement for you.

Instant Knockout Complete Key Ingredients

The ingredients list for Instant Knockout Complete is refreshingly short, focusing on quality rather than quantity. All ingredients are natural and can be found in many healthy vegan diets. There are several protein sources, fiber sources, and healthy fats.

Plant-Based Protein

There are three different plant-based protein sources contained within Instant Knockout Complete. The majority of the protein comes from pea and soya, both of which are often used in vegan protein powders due to their quality protein content and amino acid profiles.

Organic brown rice concentrate is another excellent plant-based protein source, which contains the three branched-chain amino acids (leucine, isoleucine, valine). There is also protein that comes from chia seeds, which we will discuss later.

The different protein sources combine well to provide a complete amino acid profile for the meal replacement shake, meaning that you are getting optimal protein in each serving.

Golden Flax Seed

Flax seed is very popular in health and fitness circles due to its omega 3 fatty acid content and fiber content. Omega 3 fatty acids have been associated with improved heart health, reduced risk of colon cancer, and improved mood. Fiber is also beneficial, with high-fiber diets leading to better weight management, appetite control, and reduced risk of heart disease, to name just a few benefits.

Chia Seed

Chia seeds, like flax seeds, are popular for the micronutrients they contain. Chia seeds are a great source of omega 3 fatty acids, calcium, manganese, and dietary fiber. They also contain protein. Chia seeds are particularly popular in vegan diets due to their protein content and omega 3 and calcium content.

MCT Oils

MCT stands for medium-chain triglycerides. These are healthy fats that provide numerous benefits. They can raise your metabolism slightly and help with weight loss (when replacing regular oils).

They are also being looked at for their ability to help your body to prioritize burning fats for fuel over carbohydrates. This can help you burn more fat during a workout than when using regular fats.

Oat Flour

Instant Knockout Complete uses oat flour for its carbohydrate source. This is because oat flour has a very low GI score, just 37. This means that instead of a short burst of energy followed by a crash, you get a long sustained energy increase, helping you to focus and avoid crashing.

Oat flour is also an excellent source of fiber, which can help increase satiety (feeling full after a meal) and help you avoid snacking.

Benefits of Instant Knockout Complete

There are many benefits to using Instant Knockout Complete, both health-related and practical. Here is a selection of six benefits:

Only 400 calories per serving

Whether you are trying to lose weight, maintain a healthy weight, or gain weight, it is essential to have some control over the calories you are consuming. Having a supplement that offers an exact calorie total is incredibly helpful at creating control.

400 calories is a great calorie total; it is high enough to sustain you while containing enough healthy fats, protein, and carbohydrates. While helping you to save calories. A typical breakfast can have around 500 calories, with many breakfasts reaching 600 or even 800!

There are lower-calorie meal replacement shakes out there, often around 200 calories, but unless you are on an ultra-low calorie diet, this will not be enough to sustain you.

Fantastic source of fiber

Fiber has many health benefits, reduced risk of cardiovascular disease being the most celebrated. From a weight-loss perspective, fiber is great at increasing satiety, meaning that you will feel full after a high-fiber meal.

Instant Knockout Complete contains 45% of your recommended intake, making it a lot easier to hit your daily target.

Vegan friendly

There are many meal replacement shakes out there, but many of them use whey protein or other dairy products. This makes them unsuitable for vegans, who are (in some ways) most in need of high protein meal choices.

Instant Knockout Complete has been very careful in its ingredient selection, meaning that it is vegan-friendly. This does not mean that non-vegans should avoid it, though, still benefit from plant-based protein sources.

High protein content

The protein content of Instant Knockout Complete is surprisingly high. A typical meal replacement shake contains around 20 grams per serving, a good one will have 25 grams. Instant Knockout Complete includes 35 grams of plant-based protein per serving.

For a standard 2,000 calorie diet, this represents 70% of your recommended protein intake. However, most fitness experts agree that the recommended protein intake is too low. Either way, 35 grams of protein per serving will make it a lot easier to hit your protein target for the day.


One of the most significant selling points of meal replacement shakes is how convenient they are. Compare the steps required to mix one meal replacement shake (see next section) to the steps needed to make a regular high-protein breakfast or lunch.

No eggs are cracked, no vegetables cut, no meat grilled. Just the addition of powder to water, yet the meal replacement shake is healthier than most breakfast or lunches available!

Storage is easy. No chance of a missed expiry date. Washing up is simple, just run the shaker under some hot water and scrub clean in seconds. No recipe books required.

FDA approved facility

Instant Knockout Complete is made in FDA-approved facilities, meaning that you can rest assured that what you are consuming is safe, legal, and well looked after.


How to Take Instant Knockout Complete

One serving is two 50 gram scoops (total 100 grams). Add the two scoops to water, milk, or a vegan milk alternative. Use a shaker, put the lid on tightly, and shake like crazy. Once you’ve done that, you can either pour it into a glass or drink straight from the shaker. Simple!


Pricing on Instant Knockout Complete

There are three options for purchasing Instant Knockout Complete. You can either purchase one pouch, which contains 14 meals, for $65, purchase two pouches for $130, or three pouches (42 meals) for $195.

There is no difference in price per pouch when you buy two or three instead of one however, there is free shipping for the two larger orders, which makes them greater value for money.


What About Shipping With Instant Knockout Complete?

There is free shipping to the US and UK for the two larger orders. For the smallest order (one pouch) there is a shipping fee. For that fee you get tracked USPS priority shipping which should arrive within 2-4 days.



Instant Knockout Complete is a great addition to the meal replacement shake industry, offering a very high protein product made from all-natural ingredients at a reasonable price. It will suit both men and women and is perfect for vegans, particularly vegans looking to lose weight.

As a meal replacement shake, it tastes great, mixes well, and has a wonderful consistency. The light vanilla taste combines well with milk, vegan milk, or water, and is neutral enough not to get overpowering over time.
