Why you should trust us

Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

We extensively test each health service or product we review. We try our best to give you, our readers, an unbiased exploration of at-home health options, free of marketing jargon or gimmicks. We evaluate products and services based on their adherence to quality, the latest medical evidence and health standards, and a simple question: would we buy the product or service ourselves if it weren’t part of our job, and would we recommend it to family and friends?

Additionally, like all health-related content on this website, this review was thoroughly vetted by one or more members of our Medical Review Board for accuracy.

What is Leanbean?

Leanbean is a fat-burning supplement designed specifically for women. It’s manufactured by Ultimate Life Ltd., a well-reputed, UK-based company known for its popular weight-loss products. Leanbean contains all-natural ingredients, including glucomannan, choline, green coffee extract, turmeric, and B vitamins.

Leanbean approaches weight loss for women based on evidence that women have a tougher time avoiding cravings than men do. Thus, its primary ingredients focus on appetite suppression and boosted energy without harmful stimulants. Additionally, it contains natural thermogenics and minerals that boost metabolism, fat-burning capabilities, and energy.

Each serving of Leanbean is two capsules, which you take 30 minutes before meals with at least 1-2 glasses of water, three times daily.

How Leanbean works

Leanbean combines several natural ingredients aimed at appetite suppression, metabolism-boosting, and efficient, healthy digestion. Below, we’ll examine the science behind each ingredient and the scientific studies that demonstrate its potential uses and effects.

Ingredient amounts listed below are per serving (two capsules).

Glucomannan (1000 mg)

Glucomannan, derived from the root of the konjac plant, is a water-soluble fiber supplement. Many studies have been conducted on glucomannan's effectiveness in weight loss for obese individuals, with varied results. For instance, this study in 2013 determined that over eight weeks, subjects taking glucomannan showed no significant weight loss compared with those given a placebo.

However, this systematic review and meta-analysis of randomized controlled trials concluded that glucomannan consumption significantly reduced weight in obese adults and showed promise for supplementation as a practical approach to weight loss. Glucomannan works as an appetite suppressant by swelling in the stomach when combined with water, giving the sensation of fullness. Note that all studies showing the effectiveness of glucomannan for weight loss are within the context of an energy-restricted diet.

Choline (27.5 mg)

Choline is an essential nutrient obtained from the diet, as human production is generally insufficient. Deficiencies in choline are rare but can lead to nonalcoholic fatty liver disease and muscle damage. Choline is naturally found in organ meats, egg yolks, dairy products, legumes, vegetables, pasta, and rice.

Leanbean cites this study to demonstrate choline's positive effects on normal lipid metabolism, liver function maintenance, and homocysteine metabolism. However, we found this study even more compelling in showing evidence that choline supplementation can encourage rapid body mass reduction in athletes.

Chromium picolinate (11.7 mcg)

Chromium picolinate is a chemical compound often found in supplements for its potential in treating type 2 diabetes and promoting weight loss. This 2013 meta-analysis of randomized controlled trials of chromium supplementation on overweight and obese subjects showed some evidence of a relatively small reduction in body weight. However, the researchers ultimately concluded that there was not enough evidence to firmly support the idea that chromium picolinate would significantly affect overweight or obese patients.

Vitamins B6 and B12 (566.67 mcg and 0.8 mcg)

B vitamins are essential for brain function, heart health, and energy production. Vitamin B12 deficiencies, in particular, can arise in vegans, vegetarians, older individuals, and people struggling with digestive issues.

B vitamins are credited with several benefits related to weight management and cognition. While this study employed rats as its trial subjects, it did produce evidence supporting B vitamin supplementation as effective in reducing body weight gain and plasma levels of lipids by improving metabolism-related enzyme activities.

Additionally, conclusions in this 2020 clinical review support evidence that supplementing individuals with B vitamins is likely to result in health benefits in the areas of mental and physical fatigue, as well as cognitive and psychological functions.

Chloride (3.33 mg)

Potassium chloride is used in treating hypokalemia (low potassium) as an electrolyte replenisher. Studies have shown its potential for reducing body mass index (BMI) in combination with lifestyle modification. However, further trials are needed to determine if an increase in dietary potassium might improve weight outcomes in the treatment of obesity.

Zinc (3.67 mg)

Zinc is an essential trace element required for the function of enzymes, DNA and RNA metabolism, and gene expression. Studies have shown that zinc supplementation, alongside a restricted-calorie diet, has favorable effects in suppressing appetite and may effectively treat obesity.

Green coffee (16.67 mg)

Green coffee extract (GCE) is derived from unroasted coffee beans. It is a common ingredient in weight-loss products but lacks sufficient clinical evidence to support its effectiveness or safety for this use. Its inclusion in weight-loss products has garnished controversy for several years following the fallout from an episode on the Dr. Oz Show that led to a proponent of GCE being fined $9 million by the Federal Trade Commission for making unsubstantiated claims regarding GCE products.

With that said, studies on the impacts and benefits of GCE are conflicting and largely conclude insufficient evidence of claims for weight loss.

A 2010 systematic review and meta-analysis of randomized clinical trials on the use of green coffee extract as a weight-loss supplement concluded that the results were promising but that the studies were all of poor methodological quality. More rigorous trials were needed to assess the efficacy and safety of GCE as a weight loss supplement.

However, a more recent analysis from 2020 showed that GCE supplementation improved fasting blood glucose, serum levels of insulin, and total cholesterol.

Turmeric (16.67 mg)

While not specifically targeting weight loss, turmeric supplements have proven effective in addressing many health issues.

Turmeric is a spice derived from the rhizome of a plant within the ginger family native to the Indian subcontinent and Southeast Asia. It has been used for centuries in cuisine and Ayurvedic medicine. The antioxidant curcumin derived from turmeric has undergone extensive studies for its many health benefits, including reducing inflammation and improving insulin sensitivity and elevated blood pressure.

Garcinia cambogia (33.33 mg)

Garcinia cambogia is a tropical fruit native to South Asia and Southeast Asia. It has been promoted as an effective appetite suppressant in several dietary supplements. However, side effects from some of these products (including liver toxicity and gastrointestinal issues) have led to their withdrawal from the market.

In a systematic review and meta-analysis of randomized trials on the effectiveness of Garcinia cambogia as a weight-loss supplement, evidence suggests that Garcinia extracts generate short-term weight loss. However, the magnitude of the effect is negligible.

Acai berry (6.67 mg)

Acai berries are the fruit of a palm tree native to South America. While no independent studies have been published that substantiate claims that acai promotes rapid weight loss, an uncontrolled pilot study showed that its consumption reduced levels of selected markers of metabolic disease risk in overweight adults.

Piperine (1.67 mg)

Piperine, an extract from black pepper, plays the role of aiding in the absorption of other vital nutrients in Leanbean, essentially boosting them.

Is Leanbean effective?

In our experience, Leanbean boosted energy and reduced cravings and the tendency to overeat. It benefited our already-active lifestyles, giving us energy for longer workouts and curbing the desire for unhealthy snacks.

However, the ingredients that Leanbean promotes as scientifically proven fat burners are more complicated. Some of these ingredients have shown promise for their weight-loss abilities, but most of them lack enough solid scientific evidence to show efficacy in reducing weight in overweight or obese individuals.

Ultimately, Leanbean may effectively deliver weight loss when used with lifestyle changes, including regular exercise and a healthy diet, but taking the capsules alone is likely to have a minimal effect.

Is Leanbean safe?

Leanbean's ingredients are all-natural, and few users have reported significant side effects. However, it’s always advisable to talk with your doctor before adding a new supplement.

Some ingredients, such as Garcinia cambogia, can cause gastrointestinal distress above the recommended dosage, so consuming no more than six capsules daily is essential. Pregnant and nursing women, in particular, should consult with their physician before use, and we recommend the same for anyone who has a history of allergic reactions to food or nutritional supplements.

Is Leanbean a good value?

Leanbean is comparably priced with many of its weight management and fat-burning competitors. When compared with other brands, its price point falls in the mid-range. For example, it is more expensive than Hum Skinny Bird ($40/month) but cheaper than Bio-X4 ($99/month).

How we evaluate health products and services

At Innerbody Research, we customize our evaluation criteria depending on the type and nature of the health-related service or product. But in general for health products and services, we have five broad areas that we explore in our evaluations, including:

Quality: How well does the company deliver its core service(s) to the customer? For testing services, does the company adhere to the latest and most advanced testing technologies and achieve a very high degree of accuracy? For non-testing telemedical or teletherapy services, is the quality of the service high enough that we would recommend it to loved ones without hesitation? If not, why not? For health products, does the product or device meet a high level of safety? Is it manufactured with high-quality standards? Has it -- or have its ingredients – been subjected to studies that confirm effectiveness?

User-friendly: How intuitive and convenient is the service or product? Does the device, program, app, or website achieve a good degree of user-friendliness for its customers?

Value: Are you getting your money’s worth? Are there any hidden costs or charges? Does the company offer discounts?

Privacy: If health data is stored, will your data be stored securely? Are payments secure? Does a company market your information?

Customer support: Particularly in situations where ‘one size fits all’ doesn’t make sense, how well does the company help make the service or product ideal for you or address your individual needs?
