  • Fiber: 15g
  • Micronutrients: 26 essential vitamins and minerals

One of the most important aspects of Instant Knockout fat burner is its micronutrient content. Micronutrients refer to the vitamins and minerals contained within the shake. It contains 26 essential vitamins and minerals that work together to facilitate numerous processes in the body. This includes fat burning as well as immune and metabolic functions.

Having such a wide variety of micronutrients allows the body to perform at an optimal level when following a meal replacement plan.


Instant Knockout Complete is made from natural ingredients that are plant-based, vegan-friendly, and gluten-free. The main ingredients are:

  • Plant-based Protein: This ingredient is a blend of pea and soy protein isolate, which are high-quality sources of protein that contain all nine essential amino acids. Protein is important for your muscle growth and repair, as well as your appetite control and metabolism. Instant Knockout Complete provides you with 35 grams of protein per serving.
  • MCT: This ingredient is a type of fat that comes from coconut oil. MCT stands for medium-chain triglycerides, which are fats that are easily digested and absorbed by your body. MCT can help you burn fat faster by increasing your metabolic rate and fat oxidation. They can also help you reduce your body weight by suppressing your appetite and enhancing your satiety. Instant Knockout Complete provides you with 10 grams of MCT per serving. (1)
  • Golden Flaxseed: This ingredient is a seed that is rich in omega-3 fatty acids, fiber, lignans, and antioxidants. Omega-3 fatty acids are beneficial for your heart health, brain function, and inflammation. Fiber can help you lower your cholesterol, blood sugar, and weight by improving your digestion and reducing your hunger. Lignans are phytoestrogens that can help balance your hormones and protect you from certain cancers. Antioxidants can help you fight off free radicals and prevent cellular damage. Instant Knockout Complete provides you with 5 grams of golden flaxseed per serving. (2)
  • Chia Seed: This ingredient is another seed that is rich in omega-3 fatty acids, dietary fiber, protein, calcium, and other nutrients. Chia seeds can help you hydrate yourself by absorbing water and forming a gel-like substance in your stomach. They can also help you feel full longer by slowing down the digestion of carbohydrates. Instant Knockout Complete provides you with 5 grams of chia seed per serving.
  • Oat Flour: This ingredient is a type of carbohydrate that comes from ground oats. Oat flour is a low-glycemic index (GI) carb, which means it does not spike your blood sugar and insulin levels as much as high-GI carbs, such as white bread. Oat flour can help you sustain your energy levels, as well as your mood and cognitive performance. It can also help you lower your cholesterol and blood pressure by providing you with soluble fiber. Instant Knockout Complete provides you with 40 grams of oat flour per serving.
  • Organic Brown Rice: This ingredient is another type of carbohydrate that comes from whole grain rice. Brown rice is a complex carb, which means it contains more fiber, vitamins, minerals, and phytochemicals than refined carbs, such as white rice. Brown rice can help you regulate your blood sugar and insulin levels, as well as your appetite and weight. It can also help you prevent constipation by providing you with insoluble fiber. Instant Knockout Complete provides you with 10 grams of organic brown rice per serving. (3)

These are the main ingredients that Instant Knockout Complete uses to give you a complete and balanced meal that can support your fat loss, muscle gain, and overall health. You can also find other natural ingredients in this product, such as cocoa powder, natural flavors, stevia leaf extract, and more.

The potent thermogenic and metabolic boosting ingredients like green tea extract and cayenne pepper provide a noticeable energy boost while assisting with appetite control and fat loss. Users state they no longer experience the usual midday slumps and frequently comment on having more sustained energy levels throughout the day.

The all-natural formula is also praised for lack of unwanted side effects. While some mild jitters or increased caffeine sensitivity may occur for sensitive individuals, most report no issues with caffeine content. This sets it apart from other popular fat burners on the market which tend to cause more jitteriness or other side effects in some people. The transparent labeling of ingredients and dosage amounts also builds trust with customers that there are no hidden stimulants or fillers in the proprietary blend.

Browsing through hundreds of verified purchase reviews on retailer sites reveals a high level of customer satisfaction. A majority seem to achieve visible fat loss results within 4-6 weeks when combining Instant Knockout Complete with a healthy diet and exercise routine. Many state they reached their weight loss goals faster than anticipated. Repeat purchases and positive word-of-mouth also attest to its effectiveness as a top thermogenic supplement for both men and women striving to shred body fat and maintain a lean physique.

Here is what some satisfied customers had to say. A customer named Trey says “Tried instant knockout. One thing I like are the ingredients. All natural. Didn’t feel any true side effects besides having a ton of energy at night. Don’t recommend taking the last dose late in the evening. 5PM tops. Instant knockout made me sweat in the gym a lot more than usual. Probably the first fat burner I’ve taken that allowed me to see my abs. You must clean your diet up slightly and workout while taking the product. This isn’t going to help you lose weight if you’re eating high cholesterol foods with no exercise. I rate 4 stars and hope amazon continues to sell this product.”

Another customer named Michel says “This is my second time using this to drop the dreaded winter weight gain. Worked great last time so I expect similar results. I learned last time to drink a lot of water with it. When I say a lot I mean 16-24 oz. each dose, this avoids any upset stomach and keeps you hydrated. Eat right snd do at least moderate exercise and this will work.”

Dmitriy, another happy customer also says “Using system cut + complete almost 2 months. Also, as the bonus for purchase, I received a Hunter Test t-booster. Just one word – AWESOME! The only cons is that premium quality is quite expensive) but with the special offers affordable. Highly recommended!”

While most of the customers are happy with Instant Knockout Complete meals shake supplement, there are some people report not having adequate weight loss without exercise.

Erin is one such customer and here is what he says. “I think the hunger suppressant works or it was my mind set to eat less to lose weight that controlled it, but target belly fat and lose fat weight I haven’t noticed as I took them because my job is long hours of not moving, the actual fat loss would probably be due to the exercise it recommends, so if your wanting these to lose belly fat without putting in the work I’d save my money and just will power yourself to eat a lil less and skip that snack or trade the chips for a fruit bowl or something, probably get the same results”

Bottom Line

Instant Knockout Complete Meal Shake is an effective option for a meal replacement shake that can help with weight loss and body transformation goals. The unique formula provides a complete balanced macronutrient and micronutrient profile to support not just weight loss but overall health and wellness.

While meal replacement shakes alone will not guarantee results, Instant Knockout Complete Meal Shake takes out the guesswork of counting calories and macros, allowing you to focus your energy on consistently following the diet plan and putting in the work in the gym. Replacing one or two meals per day with this shake gives your body the fuel it needs while sticking to a calorie deficit.

However, no shake or supplement can do the work for you. For best results and sustainable transformation, exercise is imperative. Incorporate both cardio and strength training into your routine to burn calories, build muscle, and sculpt your physique. Consistency is also key – don’t give up after a week if you don’t see dramatic changes on the scale. Stick with the program and steady progress will come.

If you’re ready to commit to better nutrition, more activity, and putting in the effort to reach your goals, then Instant Knockout Complete can be a helpful addition to support your journey. Just remember – no shake is magic on its own. Achieving a fit physique requires dedication in both the kitchen and gym. With Instant Knockout Complete Meal Shake fueling your efforts combined with hard work, you’ll be on the fast track to knockout results.
