Instant Knockout Ingredients

Green Tea Extract

Green tea extract contains caffeine and catechins to aid with energy expenditure, which in turn helps you lose weight. The high concentration of these two polyphenol antioxidants found only in green teas can help support a healthy metabolism by speeding up your body’s natural ability burn fat stores for fuel.

In 2017, green tea extract supplementation was found to increase brown fat activity and help individuals lose weight.

The caffeine in green teas is combined with catechins which work together synergistically increasing norepinephrine production for greater energy expenditure through the oxidation of fats by this process known as “fat burning” or thermogenesis (the body’s natural heat generating machinery).

Cayenne Pepper Seeds

Cayenne and chili peppers contain antioxidants, vitamins that help with weight loss.
Capsaicin has been known to activate the sympathetic nervous system (which helps regulate metabolism), increase energy expenditure by increasing your rate at which calories are burned off in cold-thermogenesis via brown fat cells or white adipose tissue; reduce cravings for salty/sweet food because capsaicanics also reduces appetite while improving satiety.

It can even improve exercise performance among people who work out regularly since it speeds up physical recovery time after intense workout.


Glucomannan is a water-soluble fiber from the tuber or root of an elephant yam, which grows in tropical areas around Asia. The plant has been used for centuries as food and medicine but it’s most well known as supplement that can help people lose weight when taken regularly over time. However, studies show inconsistent results about whether this works on average to reduce someone’s BMI (body mass index).

Caffeine Anhydrous

Caffeine anhydrous is a highly concentrated powder made from the dehydration of caffeine-containing plants that has been shown to help reduce weight, fat mass and BMI. Caffiene can also improve mood as well decrease pain during workouts for those who consume it before exercise or meals (approximately 0 – 4 hours).

Vitamin B6

Vitamin B6 is a water-soluble vitamin that helps to regulate metabolism in the body. It also assisting with biosynthesis of amino acids and other nutrients, which means it’s necessary for many different aspects about your health.

Vitamin B12

This vitamin is necessary for carbohydrate and fat metabolism within the cell. It’s also required for some amino acids, so it has an effect on your muscle mass as well.

GTF Chromium

Chromium is an essential trace mineral and it’s the biologically active component of glucose tolerance factor (GTF), which enhances our ability to use insulin in a healthy way. A few animal studies have found that supplementation with GTF extracted from yeast can improve weight loss while improving body composition as well.


Zinc is a mineral that helps regulate metabolism, endocrine function and the production of testosterone to promote muscle growth. A study found that intake of supplement containing zinc with magnesium increased serum insulin-like Growth Factor 1 (IGF1), which caused an increase in your natural hormone levels for optimal strength development.

Minerals are essential parts our bodies because they provide stability to cells through their antioxidant properties while regulating different metabolic processes like energy storage or food digestibility without harmful side effects.


Piperine is an alkaloid found in black pepper extract. Studies show that it can inhibit the creation of new fat cells, leading to weight loss and lower cholesterol levels for those who are overweight or have diabetes; one animal study even showed how piperine prevented obesity-induced metabolic syndrome by decreasing body fat mass while increasing blood lipids.

Green Coffee Bean

Green coffee bean extract is a natural weight loss supplement that comes from unroasted and higher chlorogenic acid levels in comparison to roasted beans. A meta-analysis found supplementation with green extracts for more than 4 weeks significantly reduced BMI, body weight; greater effects have been shown among those weighing 25kg or less per square meter of height.

Side Effects, Safety, and Dosage

The max dosage for Instant Knockout is 4 capsules per day.

Take one capsule before breakfast, lunchtime and after dinner for best results. If you have trouble sleeping in the evening then take your second dose of Instant Knockout at least three hours prior to bedtime so it’s not interfering with sleep patterns any more than necessary.

It’s important to have a few hours between your last dose and when you go bed. You will want some time for sleep, so it’s best if the Instant Knockout doesn’t come right before bedtime or after an afternoon nap.

The supplement contains green coffee bean extract as well as caffeine from other sources like green tea leaves; all of which can cause drowsiness in those who consume them.

Caffeine anhydrous is a highly concentrated form of caffeine. You may react differently to it than natural forms, which can be especially dangerous if you have any history or conditions that are related to heart problems.

Caffeine is a very common stimulant, and the FDA recommends limiting its intake to 400mg daily (an equivalent of 3 or 4 cups coffee). This product contains multiple forms of caffeine so it may be easy for you to exceed this limit.

Excess caffeine can lead to restlessness, nausea and agitation. In some cases it has been known that rapid intake of over 1,000 mg or higher has caused seizures and even death.

Instant Knockout contains multiple stimulants, so it’s best not to take this supplement with other products that also have caffeine. If you do decide on having some coffee or tea while taking your supplements make sure they don’t both contain any form of espresso in order for the effects of those drinks won’t cancel each other out and cause an unsafe intake level.

Glucomannan has been associated with side effects like increased belching, bloating and other uncomfortable digestive issues. This supplement should not be taken by pregnant women or nursing mothers as it may lead to negative consequences for baby.

There are a lot of things that you should know about this supplement before using it. Be sure to consult your doctor and find out if it’s right for you, especially in light health conditions or medications currently taking.
