Leanbean and Instant Knockout are both popular choices among fat burners that are suitable for women. While they both target the same audience, their overarching goals couldn't be more different. Not to mention the fact that Instant Knockout is just as suitable for men as well.
Let's analyze the compositions and proposed benefits of Leanbean and Instant Knockout to define their differences. This will also help us figure out which one is the better option for you.

What is Leanbean?
Leanbean claims the title of ultimate fat burner for women or is at least a pretender to the throne. According to their official website, the primary objective of this supplement is to give women a healthier and more active lifestyle.
How it works
Leanbean presents a multi-layered plan to help women lead healthy lives. From what we understand, the first step in achieving this goal is to reduce fat concentration by boosting fat oxidation and regulating metabolism. The ingredients listed for these benefits include Chloride, Turmeric, and Choline.
The next step is to suppress hunger and cravings for sugar-filled foods with Glucomannan. Leanbean's reasoning is that snacks, especially sugary ones, add the most destructive and easily disregarded calories into our system, so they strive to help you control your craving.
The final step of its proposed plan has two steps. One, increase energy levels and stamina with minerals like Chromium and Zinc, and two — reduce the symptoms of fatigue with Vitamin B6, B12, and Caffeine.
If this supplement works as advertised, regular intake should allow you to lose weight quickly, develop healthy eating habits, and stay more active with a proper workout routine.
What is Instant Knockout?
The first major point to understand about Instant Knockout is that, unlike Leanbean, it is not just for women. Instead, it positions itself as the ideal fat-burning supplement for anyone looking to achieve a well-toned body — man or woman, young (18+) or old.
Proposed Benefits
While Instant Knockout advertises a number of benefits, most of them revolve around the idea of getting in better shape. It claims to boost your body's natural fat-burning capabilities by enhancing Lipolysis and thermogenesis.
It also claims to augment your stamina & energy levels and reduce post-workout fatigue. This way, you'll be able to build muscle faster by working out harder and for longer periods.
Composition
Instant Knockout's list of ingredients includes popular fat-burning components like Green tea extract and Caffeine, alongside energy boosters such as L-Theanine and Cayenne pepper. Another significant ingredient of this supplement is Glucomannan which is a hunger-suppressing dietary fiber.
Shared ingredients
Leanbean and Instant Knockout have four ingredients in common, including:
Glucomannan
Glucomannan helps your weight loss efforts in a number of ways, but its most effective role is as a hunger suppressant. Regular Glucomannan intake makes you feel fuller with less food, and the feeling of being sated is prolonged when you consume it.
Studies also suggest that it can reduce the amount of protein and fat absorbed by our bodies which slows down weight gain due to your diet.
Vitamin B6
This ingredient primarily helps maintain a healthy metabolism. Vitamin B6 and its derivatives are essential components in over a hundred enzymes required in protein metabolization.
Regular Vitamin B6 intake is also linked with higher dopamine and serotonin levels. While this doesn't provide any weight-loss benefits directly, it does keep you motivated and focused on your workouts.
Vitamin B12
Vitamin B12 deficiency can lead to chronic fatigue that doesn't go away no matter how much you rest. Taking B12 supplements can counteract this fatigue — allowing you to be fully active again. Some studies also suggest that B12 consumption can boost energy levels if paired with a nutritious diet.
Piperine
While Piperine doesn't have any direct benefits of its own, it can increase the bioavailability and effectiveness of the other ingredients by 30% or more.
Leanbean unique ingredients
Leanbean contains 12 ingredients, 8 of which are unique to this supplement. The most notable ones being:
Choline
According to a 2014 study by Elsawy et al., regular Choline consumption can quickly reduce excess body mass, especially in athletes.
Chromium
Chromium is a hunger suppressant that makes you feel fuller. But, unlike Glucomannan which achieves this effect by taking up space in your stomach, Chromium amplifies the CCK signals from your brain — causing your brain to signal to your body that it doesn’t need food. Though it is important to note that more research is needed to confirm this interaction.
Chloride
Chloride ensures proper digestion by maintaining normal pH levels in your stomach. This allows your body to absorb more nutrients from food and stay in good shape.
Zinc
Zinc promotes a healthy energy-yielding metabolism, which increases your energy levels and allows you to stay more active. Studies also suggest that regular Zinc intake can reduce the risk of obesity and diabetes.
Green Coffee
Multiple animal studies show a direct correlation between Green Coffee extract and weight loss. The extent of these benefits on humans is not fully understood yet, but researchers believe that it is effective and so it’s worth considering.
Instant Knockout unique ingredients list
Instant Knock includes five unique ingredients in its formula. The ones that help you get toned are:
Green Tea Extract
Green Tea on its own is a popular drink for weight loss, and the main reason for this is its ability to boost fat oxidation. It achieves this by increasing your body's energy expenditure, signaling your body to convert more fat into usable energy.
A 2011 study by Kim et al. also showed how regular Green Tea extract intake could increase body temperature via thermogenesis — augmenting fat metabolism.
Vitamin D3
Studies show a direct correlation between regular Vitamin D3 intake and lower body mass index for women. These results were also observed after just 12 weeks of use. It also lowers the risk of high blood pressure and keeps your overall cardiovascular health in check.
Caffeine
Caffeine has a bigger effect on your weight loss efforts than you might think. It can boost thermogenesis, which allows you to shed extra weight much faster with the right workout routines.
Speaking of workouts, regular Caffeine intake also boosts your energy levels and increases your muscle strength. With these benefits, you can drastically increase the intensity and duration of your exercises and resistance training.
Dosage
The recommended dose for Leanbean is six capsules a day. According to its official website, you should take these capsules two at a time, three times a day.
Instant Knockout, on the other hand, requires you to take four capsules in one day. You have to put an equal duration between each capsule. The times recommended by Instant Knockout's website are 8 am, 11 am, 2 pm, and 5 pm.
Side effects
Both Leanbean and Instant Knockout report zero side effects, mostly due to their natural components.
While their lists of ingredients don't include any obviously problematic substances, you should still pay attention to how your body reacts once you start using either of them.
For instance, you shouldn't take more than the recommended amount of dosage as the high Caffeine content of these supplements will cause issues like jitters, nausea, and headaches.
Also, if you have a major illness or if you're pregnant, consult a doctor before considering these fat-burning supplements. Naturally, allergies and sensitivities to any of the ingredients in these two supplements are important to consider.
