Forever Lean Review

Forever Lean is a product manufactured by the US company ‘Forever Living’, who claim that their product can block absorption of calories from both fat and carbohydrates, as well as regulating blood sugar levels. Although there are only 3 main ingredients, they are all supported by some relevant clinical evidence, indicating that they may be safe to consume and could potentially contribute towards weight loss. The company seem reputable and the official website is very informative in terms of explaining how Forever Lean works, although information on manufacturing standards and side effects is limited, and they don’t appear to offer a money-back guarantee or diet plan.

Claimed weight loss benefits

Out of the 5 key areas of weight loss, Forever Living claim that their product, ‘Forever Lean’ has the potential to target 2 of these areas: fat burning and carbohydrate blocking, although they also say that their product may also have potential metabolism boosting properties. Although the Forever Lean capsules only contain 3 main ingredients, the formula is said to ‘block the absorption of calories’ from fat, carbohydrates and, temporarily, sugar. Furthermore, they state that some ingredients can regulate the levels of blood glucose in the body in order to improve and maintain a normal metabolism.

How Forever Lean Works

woman wondering how diet pill works 538

Forever Living provide detailed information on how their product promotes weight loss. Some ingredients claim to bind fat/reduce fat absorption, while others are said to block the body from absorbing carbohydrates and their calories. It’s said that the majority of these ingredients are binders which attach themselves to specific enzymes and molecules, a method which will be discussed in greater detail later in the article.They say that because of this, Forever Lean is also believed to regulate blood sugar levels and reduce the amount of calories that are absorbed from sugar, and this is said to encourage the body to maintain a healthier metabolism.


Chromium is a common ingredient found in weight loss products, and is said to reduce fat absorption and regulating metabolism because it’s said to act as a ‘glucose tolerance factor’. It’s believed that chromium stimulates insulin, and this allegedly causes it to transport glucose to different bodily cells and provides them with energy. A rise in energy in the cells is said to encourage and improve the breakdown of fat and glucose, which may then regulate blood sugar levels and promote/maintain a healthy metabolism, as well as reducing fat absorption.

Indian fig extract (opuntia ficus-indica (prickly pear))

Otherwise known as ‘opuntia ficus-indica’ or the ‘prickly pear’, Indian fig extract is said to be a fat binder which works at reducing fat absorption in Forever Lean. This ingredient is believed to achieve the title of ‘fat binder’ because it supposedly attaches itself to some of the fat molecules in the digestive tract. The act of binding together bits of fat makes the molecules increase in size until they’re too large to pass through the small intestine to be absorbed into the body, and it is therefore said to be forced to exit the body instead. This essentially takes bits of fat, makes them insoluble and removes them, and this process could possibly aid in reducing the amount of fat absorbed into the body.

White kidney beans

White kidney beans are used in weight loss supplements due to their claims of blocking carbohydrates. The extracts found in such products are formed from the leftover ‘husks’ when the seeds are removed from the bean pods. Carbohydrates are larger molecules which need to be broken down in order to be absorbed into the body. Traditionally, ‘amylase’ is a natural chemical found predominantly in saliva, and its role is to help break down and digest carbohydrates. However, white kidney beans are said to attach themselves to this and block the amylase so that it doesn’t break down the carbohydrates which would then be absorbed into the body.

Similarly to how the fat binders work, the white kidney bean extract has now formed a large insoluble molecule that can’t be absorbed into the body, and is therefore said to be forced to exit the body elsewhere.

Key Forever Lean Ingredients

molecular 538

Unlike many weight loss supplements that contain large blends of ingredients, Forever Lean is only made up of 3 main ingredients which are all natural: chromium, white kidney bean extract and Indian fig extract, which is also known as ‘opuntia ficus-indica’ or ‘prickly pear’. Nonetheless, these ingredients are supported by relevant clinical evidence in terms of potential weight loss properties and Forever Living take pride in promoting them as being kosher, as well as having an ‘Islamic Seal of Approval’.


Chromium is a mineral classed as an ‘essential trace element’ because the body requires it in small amounts. In medicine, chromium is said to increase insulin levels which is said to improve/regulate blood sugar levels as well as increasing levels of serotonin in the body, and this is why it’s used as an ingredient in anti-depressants. In addition, others use chromium to reduce bad (LDL) cholesterol and raise good (HDL) cholesterol, while others use it to treat polycystic ovary syndrome.

Indian fig extract (opuntia ficus-indica (prickly pear))

Indian fig is also known as ‘opuntia ficus-indica’ or ‘prickly pear’ and is made from the cactus plant, and is said to be part of a Mexican diet. The juice from this plant is said to be used as an ingredient in jelly and sweets. Extracts of this plant can also be used for medicinal purposes; as well as allegedly fighting viral infectons, there are also claims of it treating high cholesterol, type-2 diabetes, obesity, hangovers, colitis, diarrhoea and BPH.

White kidney bean extract

White kidney beans, otherwise known as ‘Phaseolus vulgaris’, are used in weight loss products because they’re known as ‘starch blockers’, meaning that they potentially prevent carbohydrates from being absorbed into the body. White kidney beans are taken out of their bean pods in the form of seeds, and an extract is taken from the remaining ‘husks’ which is used in medicine to treat high cholesterol, obesity, urinary tract infections, kidney/bladder stones, diabetes and lung cancer.

Clinical Studies

Clinical Researcher 538

Before any new treatment such as a product, ingredient or drug is made available for public consumption, it’s important that it undergoes a series of tests and examinations so that customers are aware of its safety and potential effectiveness. Often, a randomised, double-blind and placebo-controlled format will be used to obtain clearer, more fair results. It seems that as product as a whole, Forever Lean has not been clinically studied at all. While this may reduce the validity of the claims made by its manufacturer, we can still gain an idea of how the product performs overall by exploring studies on the individual ingredients instead.


One 3 month study explored the effects that chromium had on a sample of 76 ‘normal’ subjects who received either 200mg of chromium each day or a placebo. The study looked specifically at changes in glucose, insulin and lipid variables. Out of the 76 candidates, 20 of them partook in a glucose challenge to monitor their blood sugar levels. This involved the subjects receiving serum glucose concentrations of at least 100mg (1g of glucose per kilogram of body weight) 90 minutes after the challenge. After the 3 months, results showed that although there wasn’t a huge change in levels of insulin, body weight or lipids, there was a significant drop in glucose levels. This may indicate that chromium may indirectly affect weight loss through regulating blood sugar levels, but more evidence is required.

A second study used a sample of 83 premenopausal women who were put on a regulated diet and instructed to consume a supplement containing chromium picolinate or placebo. This diet was assigned in order to allow the women to adapt to meal patterns and allow for initial measurements. Each woman was randomly given the chromium picolinate supplement, picolinic acid or a placebo, and these were to be taken before breakfast for a total of 12 weeks. Each weekday morning throughout the study, the women underwent a weigh-in before breakfast to monitor their body weights.

After the 12 weeks, results showed that although there was a change in body weight and fat mass, it may not have been completely down to the chromium picolinate supplement alone. While it may have influenced the results, they implied that it may need to be combined with other ingredients and an exercise regime, but further evidence may be needed.

Indian fig extract (opuntia ficus-indica (prickly pear))

Using a sample of 20 healthy volunteers, this study examined the effects of Indian fig / prickly pear over 45 days. The participants were randomly assigned either the Indian fig supplement or a placebo, and they were instructed to consume 2 tablets, 3 times a day alongside their main meals which were provided and 35% of daily energy came from fat. Measurements were taken through 2 faeces samples before and after the study, and results showed a significant increase in ‘faecal fat excretion’ in the volunteers consuming the Indian fig / prickly pear.

A second study observed the effect that Indian fig / prickly pear has on glucose and lipid metabolism using a sample of 24 non-diabetic male volunteers but who had hyperlipidaemia, a condition referring to an abnormal excess of fat or lipid in the blood. The age range of the sample was 37-55 years old, all of whom were non-obese. The participants were divided into groups determined by their conditions; the first group suffered from ‘primary isolated hypercholesterolemia’ while the second group suffered from ‘combined hyperlipidaemia’.

The groups had an initial 8-week ‘pre-running’ phase followed by a diet including a daily consumption of 250g of prickly pear edible pulp for a further 8 weeks. Results showed that the Indian fig / prickly pear caused a 12% reduction in total cholesterol, a 15% reduction in low-density lipoprotein-cholesterol, a 12% decrease in triglycerides and an 11% decrease in blood glucose, amongst others, but body weight remained unchanged, which means that more evidence is needed.

White kidney bean extract

Using a sample of 25 healthy subjects, the following study assessed white kidney bean extract and its ability to block the chemical known as ‘amylase’, which is responsible for the breakdown of carbohydrates into the body. Over 4 weeks, the participants were assigned either 1000mg of white kidney bean extract or a placebo, and these came in the form of 2 pills a day which were instructed to be taken before breakfast and dinner. In addition, the subjects all had their diet, exercise regime and ‘behavioural intervention’ monitored.

Appropriate measurements were taken and results showed that although both groups saw a reduction in body weight and waist measurements, the white kidney bean group saw an average loss of 6lbs in body weight and 2.2inches reduced from their waistline. Comparably, the placebo group lost an average of 4.7lbs and saw a 2.1inch waistline reduction. Furthermore, participants consuming high-carb diets with the white kidney bean extract reduced their body weight by 8.7lbs on average and their waistline by 3.3inches on average, while the high-carb placebo group only saw an average loss of 1.7lbs and 1.3inches.

Forever Lean Side Effects

Woman With Stomach Ache 538

No mention of potential safety risks/side effects can be found on the Forever Living website or its Forever Lean page. This is surprising because although this product’s formula is small and the ingredients are natural, there are still a number of precautions. They clearly state that their statements haven’t been evaluated by the FDA, but all dietary supplements are said to have safety risks. People may react differently to certain ingredients, especially if they have any type of medical condition or are using medication, and a greater insight into this can be gained by looking at each ingredient individually in terms of their alleged safety.


It’s said that chromium is likely to be safe when consumed by adults in doses of up to 1000mcg for up to 6 months, and it’s said to be possibly safe for even longer. For children, chromium should be safe when consumed in small doses for a short time. However, side effects such as skin irritation, headaches, dizziness, nausea, changes in mood and impaired thinking and judgement and co-ordination have all been reported in the past. More severe side effects that have been reported include liver and kidney damage and blood disorders, although it was never proved that chromium was the definite cause.

The following study examined the safety and effectiveness of chromium, concluding that it was recommended when taken in higher doses of 70mg per day. The researchers claimed that the chromium didn’t appear to cause any type of disease. However, they said that results depended on the dosage.

Indian fig extract (opuntia ficus-indica (prickly pear))

As Indian fig / prickly pear is commonly eaten in Mexican cuisine, it’s said to be likely to be safe when consumed as food. Furthermore, parts of the plant are believed to be possibly safe when used in medicine. However, there have been reports of side effects including mild diarrhoea, nausea, bloating and headaches. Furthermore, the following study reviewed this ingredient by examining 5 studies upon it; here, they found that several participants reported side effects including gastric intolerance and flu symptoms.

White kidney bean extract

It’s believed that oral consumption of white kidney beans by adults for roughly 2-3 months is possibly safe, although excessive consumption of the fresh raw husks are said to be possibly unsafeas they contain chemicals. It’s said that consuming too much of them can cause vomiting, stomach upset and diarrhoea. However, the FDA claim that this ingredient is generally safe when consumed as a food, and cooking is said to destroy the dangerous chemicals.

How to Use

Woman With Pills 538

Forever Living attach a PDF document containing product information including the product’s usage instructions; Forever Lean comes in the form of capsules which are said to be ingested with water ‘immediately before meals or snacks’. The directions of use aren’t strict as they say the product can be used as much or as little as different consumers require. However, they say that customers must ingest 1 capsule in each dose, and they can be taken up to 4 times a day. Each bottle contains 120 capsules, which means that 1 bottle should last for roughly 30 days.

As said before, there’s no mention of side effects or safety precautions regarding Forever Lean on the official website. There’s no comment on groups of people that shouldn’t use this product, although the Amazon retailer warns that it’s not suitable for those under the age of 14.

Due to the fact that it allegedly affects levels of blood sugar, it may be advised that those with conditions such as diabetes avoid it or at least consults their doctor beforehand. As there’s a lack of information, any customer with concerns regarding the product should consult a doctor before, especially if they’re using any medication of have any medical condition.

Who Makes It?

Forever Lean is manufactured by the company ‘Forever Living’. This company is based in the USA, which is evident from their contact details displayed on their contact page. Here, they specify that the company is based in Arizona, and they appear to ship only to the US. Their contact page contains details such as a postal address, a phone number, an email address, and customer care open hours so consumers know when they can contact them.

The company seem reputable with a large selection of products, ranging from similar weight management products/diet pills to oils, skincare products, drinks and merchandise, amongst others. This company also boasts about how their products are kosher, have an Islamic seal of approval or are certified by the ‘International Aloe Science Council’. However, although Forever Living seem highly credited with a fairly reputable history throughout their large range of products, they do fail to mention any manufacturing standards and/or they don’t seem to offer a money-back guarantee.

Nonetheless, an internet search leads to zero signs of the company being involved in scams regarding auto-billing systems, and customer reviews appear to be neutral/balanced, which may improve their image and their credibility.

Where to Buy Forever Lean


Forever Lean is perhaps more predominantly available to purchase directly from the official Forever Living site, where 1 bottle containing 120 capsules for £23.25, and this is said to last for an average of 30 days. The company doesn’t discuss delivery in great detail, and they say that due to ‘high volume’ at the end of the month, shipping times may vary. Although they’re a US-based country, they do state that Forever Lean isn’t available to be shipped to California.

The lack of information implies that Forever Lean isn’t available to purchase internationally from the UK directly from the official Forever Living website, and this may be problematic. However, the same product is available to purchase online from, where it’s sold by a UK-based seller. Here, the product is slightly more costly at £35.99 for the same 1 bottle containing 120 capsules. However, customers with an Amazon Prime membership qualify for free next day delivery to the UK. The Amazon retailer, however, claims that this product contains 100% pure aloe vera, and they offer a 60-day money back guarantee which doesn’t add up with Forever Living’s official page. Therefore, it may be advised that UK customers contact the company to discover all their options.
