9 Instant Knockout Ingredients:
Let's look at the ingredients in Instant Knockout and the studies to back the effectiveness of them below.
1. Vitamin D3 - 45mcg
Vitamin D has been shown in recent studies to have a positive effect in lowering blood pressure and inflammation, as well as in modulating processes such as cell growth, immune and neuromuscular function, and glucose metabolism, which is a good thing as it has been suggested that having a Vitamin D deficiency can result in hypertension and other adverse cardiovascular events, resulting in poor athletic performance.1
Vitamin D deficiency can also lead to a loss in bone density, which can contribute to osteoporosis and fractures. For anyone serious about working out and transforming their body, Vitamin D can be essential to your success.
2. Vitamin B6 - 5mg
Vitamin B6 is commonly found in foods such as poultry, fish, potatoes, chickpeas, and bananas. It is often used in supplements to support normal brain development, maintain the nervous system, and keep the immune system healthy.
Vitamin B6 is also used by the body to aid in turning your food into fuel to keep your weight management on the right track. Studies show that Vitamin B6 can increase dopamine levels, keep you mentally focused, and improve energy levels to crush your next workout.2
By maintaining healthy Vitamin B6 levels, you can increase your serotonin and, as a result, improve your will to exercise and eat right. People with kidney diseases or food absorption issues tend to be Vitamin B6 deficient.
3. Vitamin B12 - 10mcg
Vitamin B12 is a helpful nutrient that can keep your blood and nerve cells healthy while also helping your metabolism regulate by producing energy from your food intake. Vitamin B12 also can increase your energy, concentration, and mood, which are all factors that can impact your weight loss.
A Vitamin B12 deficiency can cause tiredness, weakness, numbness, and anemia. Not only this, but research indicates that you can prevent weight gain with long-term use of Vitamin B12, which makes the inclusion of it in Instant Knockout quite beneficial.3
4. Caffeine - 300mg
Caffeine is one of the world's most common go-to ingredients when you need a natural boost in energy. Most people need to realize that caffeine's benefits go much deeper than waking you up in the morning and motivating you through a workout.
Studies show that caffeine promotes weight, BMI, and body fat reduction, as well as aid with aerobic exercise, power output, running capacity, and many more benefits, which shows the versatility and functionality of caffeine.4
The inclusion of caffeine in Instant Knockout helps give you more energy and aid in weight management. Due to the inclusion of caffeine in Instant Knockout, we don't recommend taking it late at night, as it can result in difficulty falling asleep.
5. L-Theanine - 100mg
In most cases, L-Theanine is typically used in supplements as a cognitive compound to relax and sharpen your focus, mainly when the supplement contains a significant dose of stimulants like caffeine.
Not only can it help to calm and relax the mind, but it can also help with increasing sleep quality, resulting in better rest periods and more energy to smash your goals. You may also experience indirect health and fitness benefits of L-theanine which will result in procuring a leaner and more cut physique.
Its direct benefits for weight loss are L-Theanine's ability to suppress appetite, reduce fat accumulation, and improve sleep-related fat loss.5
6. Green Tea Extract - 500mg
Green tea is one of the most common forms of tea consumed worldwide. Green tea extract is renowned as a great source of antioxidants and has a broad range of health benefits.
Green tea has been credited for its fat oxidation and energy expenditure properties and is packed with bioactive polyphenols called Catechins. It also promotes heart, liver, brain, and skin health.
This diverse ingredient helps your weight management in a couple of different ways. It can help regulate the hormones that enhance thermogenesis. It has also been shown in studies to make your body more effective at burning calories, resulting in better weight loss.6
If you tend to eat too many carbs, studies have also shown that green tea extract can assist in starch digestion, helping you to beat the bloat.
7. Cayenne Pepper - 100mg
Cayenne pepper is a natural herb that can improve your weight loss ability as this pepper can curb your appetite, speed up your metabolism, and increase the number of calories burned. The main ingredient in cayenne pepper is called capsaicin, which research has shown benefits thermogenesis.
When you eat a spicy pepper or take a supplement with capsaicin, it causes your body's core temperature to rise and forces your body to go into cooldown mode. This change in your body causes more calories to be burned.
Cayenne pepper has also been shown in studies to enhance fat oxidation and increase energy expenditure.7
8. Black Pepper Extract - 10mg
Black pepper extract, also known as Piperine, is a bioactive chemical that can help with weight management by activating your metabolism, aiding digestion, and elevating thermogenesis.8
Black pepper extract is high in antioxidants, which studies have found can prevent or delay the damage that free radicals can cause. It also contains anti-inflammatory properties that can reduce joint swelling and blood markers of inflammation.
Thanks to its multi-purpose benefits, it's a key ingredient in the Instant Knockout formulation.
9. Glucomannan - 1800mg
Glucomannan is an extract of a simple root from the Konjac plant. This incredible root can work wonders if you're looking to manage your weight in a natural way.9 Glucomannan is a natural fiber and a complex carbohydrate that absorbs water in your stomach and fills you up when consumed.
When it fills you up, it helps to keep you satiated throughout the day, meaning you will snack less and eat fewer calories. It also works with the stomach and intestines to treat constipation and slow the absorption of sugar and cholesterol.
This, combined with the other ingredients in the Instant Knockout formula, means you're tackling your weight management from all angles and making it that much easier to achieve your goals.
Benefits of Instant Knockout:
Below we covered the benefits of using Instant Knockout besides just aiding the weight loss process.
1. Boosts Fat Loss
Instant Knockout fat burner contains many high-quality ingredients that help burn fat, control weight gain, and improve thermogenesis. As thermogenesis improves, your body has to work harder to keep it cool, resulting in burning more calories.
Ultimately weight loss comes down to burning more calories than you're taking in. However, Instant Knockout can make this much more manageable.
2. Enhances Energy Levels
When your body burns fats, more energy is released to fuel the body throughout the day. Instant Knockout keeps you energized, especially when in a caloric deficit.
You can also experience better focus, mental alertness, and clarity, which makes it easier to stay on track and motivated to achieve your goals.
3. Reduce Appetite
The main ingredient Glucomannan is a highly effective appetite suppressant due to the fact that it swells to 50 times its original size in the stomach and takes quite a while to break down.
Meaning that you will feel fuller for a more extended amount of time. This is especially helpful if you're on a lower-calorie diet.
When you feel full, you are also less likely to cheat on your diet.
Side Effects Of Instant Knockout
One of the best benefits that you will find with Instant Knockout is that it is considered by many as one of the safest fat loss supplements on the market right now. This can be attributed to Instant Knockout using all-natural ingredients, which gives the consumers the confidence that they are taking a safe supplement.
It does contain 300 mg of caffeine, which may cause jitteriness if you are caffeine-sensitive. So if you're planning to take Instant Knockout daily, then you should skip other forms of stimulants and avoid taking it late at night.
Instant Knockout does contain soy and may have slight traces of gluten. It also contains ingredients from coconut, wheat, and soy.
The facility that it is manufactured in also processes milk, soy, sesame, egg, peanuts, tree nuts, fish/crustaceans/shellfish oils products. So if you have any allergens to any of these factors, then we recommend consulting with your doctor first to see if Instant Knockout is safe for you.
