This last week, I decided that now was the time to find out more about Alli. We dug through the ingredients, side effects, customer service reports and even clinical studies. Then, we looked around the web for reviews on the product. Finally, we refined and condensed to give you the bottom line.

Alli Readers: Click here to find out why we're giving away samples of our product, Leptigen.

What is Alli?

First off, Alli is a lipase inhibitor. [1] The active ingredient is orlistat. [2] If you take one pill with each meal, it supposedly reduces the amount of fat absorbed and blocks about 25% of the fat you eat. [3] That equates to about 100 calories a day. The bottle is small and there is an easy carry container in some starter kits.

Alli is made by GlaxoSmithKline, which was founded in 2000. You can purchase supplement at local grocery stores and through trusted retailers. We like that the product is FDA-approved [4] and there are reports of weight-loss, but read on…

Alli Side Effects – “Worth It?”

The first negative relating to Alli side effects was the intensity. “If you take the medication regularly you can expect less fat to be absorbed, but there’s a catch,” said our Research Editor. “If you eat too much fat, you may have to deal with gastrointestinal issues.” [5]

“I have experienced one accident with a BM,” one user said. “I really have to watch what I eat or I will pay for it later.”

Another offered, “I have had a rough time with not being able to be too far from a rest room.”

Not all users had the same problems. Some, as a matter of fact, ate high fat meals and experienced no side effects. “I decided I would eat a fatty meal to test the effectiveness so I got a fast food combo, came home, took a pill, then ate. Nothing happened. No side effects, nothing,” according to one user.

“I found that the only side effect was my systolic and diastolic levels were reduced,” commented another. [6]

Cost – “A Bit High”

Another issue we found dieters did not like about Alli ingredients was the cost. “This has absolutely no effect on me whatsoever and I have the most sensitive stomach of all the people I know. Waste of $60,” said a customer.

“Not as much weight as I’d like to have lost for a $150 cost, at this point, four months in,” was one experience.

There are some dieters who felt the money was well spent, “You will see faster results such as lowered ldl cholesterol [7] if you include exercise and vitamins. Worth the price.”

We’ve found that over the years there’s been a consistent connection between small things, like side effects and a lesser chance of long-term results. If Alli causes adverse reactions, that could be enough to scare dieters away.

The Science – “Any Clinical Proof?”

Unlike many other weight-loss solutions on the market, Alli is clinically proven to work. However, at the maximum amount of fat grams you will reduce calories by about 100. The real key is eating a healthy diet and exercising while using the supplement. [8]. There’s also the chances of negative side effects affecting the functionality of the bowel system and intestines. [9] At DietSpotlight, we think science should do more than prove you have to cut fat or suffer the consequences.

The Bottom Line – Does Alli Work?

Are we running out to the store right this minute for Alli? Well, we certainly like the fact that the FDA has approved the medication and there’s no doubt it can block up to 100 calories a day, but we’re hesitant about recommending it because of the risk of side effects. Bowel leakage [10] is an extremely embarrassing situation and we’re not sure it’s worth it when there are clinically proven options with no adverse reactions.

If you want to get off that extra fat, we suggest going with a product that’s been tested and proven to help you reach your goals without risking the embarrassment of some gastrointestinal side effects.

Among the best products we’ve seen this year is our supplement called Leptigen. This formula contains four ingredients. All clinically-tested with results often seen in publications such as the Journal of Medicine and the journal Obesity.

Plus, we’re so confident that you’ll love our supplement that we’re offering a Special Trial Offer, which is a good sign.

Previous Alli Review (Updated September 20, 2012):

Alli - What You Should Know

Alli is a diet supplement that endeavors to assist with weight loss. This product was developed and manufactured by the major pharmaceutical company GlaxoSmithKline. The Alli diet pill is stated to be FDA approved and is commonly available without a doctor's prescription. The official Alli website addresses the supplement as an "anti-obesity wonder drug." It additionally discusses the "65 percent" of American adults that are currently overweight. Alli diet pills can be purchased through the official website for $44.99 for a 60 capsule starter container. Alli is claimed to be more effective when taken in conjunction with a healthy diet and regular exercise regimen. Alongside a healthy diet and exercise, Hydroxycut is a thermogenic for men and women to boost the metabolism, increase energy levels and assist with weight loss.

The key active ingredient found in Alli supplements is called Xenical (or Orlistat), which is generally a prescription weight loss drug. This diet pill aims to minimize the body's fat absorption or block a good 25 percent of fat that's consumed. Some potential side effects that can occur are vitamin deficiency, "loose stool" and excessive gas (flatulence). Alli can be purchased in most common drugstores and superstores across the US. This diet supplement is claimed to alter the process of triglycerides being broken down inside the body by obstructing an enzyme, which is found in the pancreas. This process prevents fat absorption. The Alli Diet Pill is marketed toward both men and women who are suffering from obesity and other individuals who are borderline obese.

List of Ingredients in Alli

Orlistat 60mg, FD&C Blue 2, Edible Ink, Gelatin, Iron Oxide, microcystalline cellulose, Povidone, Sodium Lauryl Sulfate, sodium starch glycolate, Talc and Titanium Dioxide.

Product Features

Alli is a weight loss supplement that comes in capsule form available over the counter in pharmacies and drugstores around the United States. This "wonder drug" is claimed to cut fat absorption by 25% so that the user absorbs fewer calories from what he/she eats. A key active component of the Alli diet pill is Xenical, which is also known as Orlistat. Alli is intended for adult women and men and is directed to be taken daily with water. This diet product sells for $44.99 via the official website. Like many other weight reduction supplements, a healthy diet and routine exercise are encouraged. Flat Tummy Tea is another alternative that can be mixed in a glass to increase energy and burn more calories for weight loss.


  • Alli is available to men and women that suffer from weight issues.
  • Alli diet pills do not require a doctor's prescription.
  • Alli is approved by the FDA.
  • Alli Diet Pills can be easily and conveniently purchased via the official website.


  • Consumer testimonials are absent from the official Alli website.
  • The official Alli website fails to offer a 100% money-back guarantee.
  • Some individuals may be allergic to certain ingredients found in Alli Diet Pills.
  • Alli does not offer free trial samples on the official website.
  • No before and after photos are provided on the Alli website.
  • May cause digestion discomfort. (See reader comments.)
  • Taking Alli Diet Pills can potentially result in a vitamin deficiency.

Our Conclusion on Alli

It should be noted, Stacker 2 is also a fat burner with few natural ingredients that can easily be taken on the go for weight loss. On the bright side, the Alli diet supplement is approved by the FDA. Since many other diet supplements, programs and pills aren't FDA approved, some consumers may find this approval reassuring. However, some dieters would likely be more interested in Alli supplements if the official website posted some consumer feedback, a money-back guarantee or at least a few before and after photos. Be sure to consult your doctor before taking Alli diet pills. This way you can learn more about potential side effects and about other diet supplements currently available. Before you close out of this review, you might want to consider Phentabz as an alternate source as it is a fat burner that contains DMAA, caffeine and synephrine used to burn off fat.

Alli User Tips:

7 Top User Tips

Over the years, we’ve found that Alli users want to share their experiences. After consulting thousands of user reviews and comments, we’ve collected some tips to help you learn more about this product.

“This product holds you accountable for what you eat. If you think you are going to eat the same, then this isn’t for you.” Amira


“It works, but don’t wear your nice underwear. A panty liner may help.” Ellen

Alli Scientific Abstracts:


Orlistat has been shown to have weight-loss effects by suppressing absorption of consumed dietary fat (by ∼30%). Following one and two year double-blind, placebo-controlled trials, the safety, and efficacy were determined with adverse effects being mostly gastrointestinal. Because orlistat has fat absorption capabilities, it is also able to suppress absorption of fat-soluble vitamins. It was because of this finding that it was suggested that vitamin consumption is recommended while taking orlistat. The research concluded that orlistat, through the absorption of fat, delivers a new treatment for weight-loss and weight management. Further studies are suggested during post marketing surveillance to establish orlistat’s safety and benefits in the long-term. Orlistat is a useful tool for weight-loss in obese patients who can make alterations to their diets, exercise, and behavior. [1]

Orlistat has shown to be a useful adjunctive treatment for triggering weight-loss as well as improving serum lipid levels, blood pressure and glycemic control in obese individuals with type 2 diabetes already taking metformin. [2]


Data on the effects of orally ingested gelatin shows that gelatin strengthens fingernails as well as improving nail defects. The data prompts a discussion regarding the action gelatin has on nails most likely occurring via the metabolism of amino acids oor what appears to be the specific dynamic action of gelatin. [3]

Sodium Lauryl Sulfate

Sodium lauryl sulfate delivered total protection of viruses in cutaneous-infected animals. Sodium lauryl sulfate completely prevented cutaneous lesions on mice that were pretreated with a sodium lauryl sulfate polymer formula. Intravaginal pretreatment with sodium lauryl sulfate within a buffered solution had protected against HSV-2 infection. It was concluded that sodium lauryl sulfate might be a useful tool as a microbicide in preventing sexually transmitted disease such as HSV, HIV, among other sexually transmitted disease-causing pathogens. [4]

Titanium Dioxide

Titanium dioxide nanoparticles were found to trigger pathological lesions of the kidney, spleen, liver, and brain when exposed intravenously. The data suggested that the significant effects could be caused by extremely high doses of titanium dioxide nanoparticles. Although titanium dioxide nanoparticles are being produced and used at a more rapid rate, there is a significant lack of epidemiological data backing it. Titanium dioxide nanoparticles have been studied thoroughly. However, the evidence is lacking regarding the possible health effects to backup risk assessment and management. [5]

Alli Side Effects:

In the world of weight-loss products, the words “natural” and “herbal” are often thought to also mean safe. Unfortunately, for every formula comes the potential for issues. Though Alli side effects are not guaranteed, that doesn’t exist for some that use its supplements.


Gas is a feeling of expelling air from the gastrointestinal distress through the anal cavity. Other symptoms that can be experienced along with this one may include cramps, swelling, tightness in the abdomen, and sharp pains.

What causes gas?

Gas occurs to everyone, even if it isn’t noticeable. However, it can become uncomfortable or more frequent, especially if some individuals start consuming more high fiber foods [1]. Other reasons include swallowed air, health conditions, food intolerances, especially in herbal supplements, sweeteners, and constipation.


Bloating is usually connected to other symptoms, like gassiness and abdominal discomfort. It can also cause the appearance of weight gain.

What causes bloating?

Overeating, fatty foods, and simply eating too fast are the three most common reasons for the onset of bloating. When it happens temporarily, it should not be of concern, but it is important to seek medical attention if it is related to other, more severe symptoms or lasts for an extended period.


Diarrhea is a condition in which fecal matter is loose, watery, and can occur more frequently than usual. Although it is normal for this to last a couple days, it can be considered an issue if it lasts any longer. Cramps, pain, a lack of bowel control, and an increased need to make a bowel movement may also occur with this symptom.

What causes diarrhea?

Some causes of diarrhea may include bacteria, viruses, medicines, herbs, food intolerances, small intestinal diseases, and issues with the colon.

Bowel Leakage

According to the National Association for Continence, bowel leakage can be characterized by having trouble holding a bowel movement, having liquid stools leak from the anus, and finding streaks of fecal matter in underwear [2]. Although it does affect both men and women, it usually occurs to the older population.

What causes bowel leakage?

Diarrhea, constipation, aging, childbirth, medication, and more are some causes of bowel leakage. Other, more severe issues may also cause the onset of this symptom.

Alli side effects are not felt by all its consumers, but there have been reports gas, bloating, diarrhea, and bowel leakage, just to name a few. To protect yourself from potential problems, it is always the best idea to consult with your physician before taking any supplement, especially if you’re taking prescription medications, are under 18, have a medical condition of any kind or are pregnant or nursing.



Alli has been around for quite some time, but we’ve heard rumblings from dieters wanting to learn more about Alli side effects. (Feel free to read our full Alli review.) We chose to look hard at the ingredients and clinical research. We also read hundreds of dieter comments to see what was really happening with regular use. That information was condensed to give you the bottom line.

What You Need to Know

First off, Alli is an over-the-counter version of Xenical, a prescription weight-loss medication. You take the pill three times daily, one before each meal. It is supposed to reduce fat absorption by 25%, based on clinical studies, so this could lead to increased weight-loss. You can find a small take-along case so you have Alli when you need it.

The product, offered up by GlaxoSmithKline, is an over-the-counter variety of Xenical or orlistat. The ingredient has been clinically tested and approved by the Food and Drug Administration, quite the positive. It’s available for sale online and in many stores. We like that some dieters have reported weight-loss and the FDA has given it a thumb up, but read on…

Constipation – Surprising Issue

The first issue we found interesting about Alli side effects was reports of constipation. “Alli is associated with loose stools,” says our Research Editor. “We found it quite surprising that dieters claimed to suffer from difficulty using the bathroom.”

“I have been taking Alli for about 2 weeks now, and my side effects seem to be the opposite of everyone elses. I makes me very constipated. Has anyone else experienced this?,” says one user.

“I have been on and off Alli for the last few months. It made me constipated – I NEVER suffer from constipation,” offers up another.


The most common Alli side effect is diarrhea. This is associated with the way Alli works. It traps fat and pushes it out through the intestine. “I got so tired of ruining my underpants and rushing everywhere because I had to hit the bathroom whenever I was standing for a while that I had to stop taking this stuff,” reports one dieter.

Accidents are common, as claimed by another user, “I made the mistake of eating Chinese food and had a MAJOR accident at work the following morning! I WAS MORTIFIED TO SAY THE LEAST!!”

It’s with research behind us that we suggest a connection between adverse reactions, like diarrhea, and lesser chances of long-term success. If Alli side effects cause problems with dieters, that’s not exactly a benefit.

The Science

There is clinical research backing Alli weight-loss claims – there has to be because the FDA approved the drug. The benefits, however, may not be worth the Alli side effects. It is recommended that you eat no more than 45 grams of fat each day. That adds up to 405 calories. Twenty-five percent is about 101. At that rate it would take 34 days to lose a single pound. At DietSpotlight we want science to set a product apart from other solutions. Alli just doesn’t fall into that category.

The Bottom Line

We were intrigued by Alli side effects and with a little research we found what we needed. We like that some users report weight-loss while on the medication and it has been approved by the FDA, but we can’t recommend a product that only equates to the dieter losing one pound a month. We’re also concerned by the frequent reports of diarrhea and leaky bowels that cause “accidents” when least expected.

If weight-loss is at the top of your priority list, we suggest going with a supplement that doesn’t come with harmful side effects, but does come with clinically proven ingredients.

Among the best supplements we’ve come across this year is Leptigen. We like the proprietary blend of four ingredients clinically proven to help speed up metabolism and boost fat loss. We didn’t find a single report of adverse side effects, but we did find numerous dieters talking about great results.

Also, the makers of Leptigen are confident enough in the formula to offer a Special Trial Offer, impressive.

Alli is an over-the-counter version of Orlistat, which was originally offered as a prescription medication. It is clinically proven to bind to some of the fat you consume and flush it out of the body when you have a bowel movement. Eating excessive fat, more than 15g in a meal, can result in side effects.

Alli Ingredients and Supplement Facts

Serving Size: 1 Capsule
Serving Per Container: 120
Amount per Serving % DV
Orlistat 60mg *

Other Ingredients: Edible ink, gelatin, iron oxide, microcrystalline cellulose, povidone, sodium lauryl sulfate, sodium starch glycolate, talc, titanium dioxide

We really researched Alli ingredients in order to give you the important specifics you need.


To start with, Orlistat is commonly sold under brand names such as Alli (over-the-counter version) or Xenical. [1] It is a prescription drug for weight-loss. It’s typically taken with doctor-approved exercise and a reduced-calorie diet plan.

What is it Supposed to Do?

Orlistat essentially prevents some of the fat you consume from being absorbed by the body. Instead, the excess fat is flushed out through the digestive tract. While this treatment for obesity is FDA approved, it can lead to some side effects like stomach pains, oily or fatty stools, gas, and spotting in your undergarments.

Clinical Research

According to the Mayo Clinic, “People who ate a calorie-restricted diet, exercised regularly and took Alli (Orlistat) lost an average of 5.5 pounds (2.5 kilograms) more in one year than did people who only dieted and exercised.” [2]

FD&C Blue No. 2

FD&C Blue No. 2 is an inactive ingredient found in various pharmaceuticals, dietary supplements, cosmetics and manufactured foods. It is regulated by the FDA, and is considered harmless.

What is it Supposed to Do?

The only purpose of FD&C Blue No. 2 is to function as a colorant. This is why it is often used in tablets and capsules.

Clinical Research

There is no clinical data that supports FD&C Blue No. 2 as an active ingredient for fat loss or weight reduction. However, this substance has been researched, and is considered safe as a colorant.

Edible Ink

Edible ink is often used in the manufacture of capsules, tablets, confectionary products and other foods. It is considered safe for consumption, but does not serve as an active ingredient.

What is it Supposed to Do?

The only real purpose of edible ink is to provide color to pharmaceutical capsules, dietary supplements, pastries, candy, cakes, cookies and other foods. It is often printed on edible paper made from rice.

Clinical Research

There is no published clinical research that supports edible ink as an effective weight-loss ingredient. On the other hand, this ink has been deemed safe by the Food and Drug Administration for consumption as a food coloring.

How Does Alli Compare?

I have lost weight 5 times with Alli. This last time I have taken it for 18 mths straight, and I’ve lost 35 lbs and have gone from a sz 14 to an 8! I’m 5’1″ and now weigh 135 and only need to lose 10 more. It is slow but steady! I feel so much healthier. The less you weigh, the less you eat and the less you are hungry. I have hypothyroidism too so I know it works. I just turned 50 and couldn’t be happier with my body and life! I will take it forever if I need to! All I crave is salads & veggies now. I love Alli!


I have tried Alli twice, the first time after a year of bad health, went from 159 to128. This time I started at 149 and I am down to 137, less then 10 pounds to go. I am 53 years old and about 5’2″, I don’t experience horrible side effects because for the most part I eat low fat, in addition I walk 2 to 4 miles six days a week. Taking the Alli gives me that extra motivation I need and I too will take it forever if possible

Donna King

Great Article. Thanks for the info. Does anyone know where I can find a blank “2011 IRS 940” to fill out?


DO NOT TAKE THIS PILL!!!!! I experienced extreme hair thinning after using this pill for a little over 6 months. Definitely, definitely not worth it- I regret it every day! It is better to be a lil heavier, but with a gorgeous head of hair than thinner with dull, limp, thin hair. Normally, I don’t review stuff- but I feel like everyone needs to be warned… Do as u wish, but NOT worth it. (if u do take it- make SURE you take vitamins every day)


been on this years ago when it was not A over the counter.came across this and needed to comment on this statement.any change in diet can make you lose hair.its not this pill.your body will adjust to your diet,it takes time,I follow a lchf diet lost a lot of hair,wore hats for almost a year,till my body adjusted and vitamins started working.you need to do what you need to do,get healthy,exercise,talk to your Dr. I found what works for me,it was not this,but it was my fault I didn’t take my health serious at the time.im down 130 lbs in a yr. it’s possible.dont give up.if this is affordable and works for you.do it,everybody is different.



Did your hair grow back?

Nye Stevens

I have been taking Alli for about two years and I have no complaints other than it is expensive and hard to find discounts. Costco the best. I am 70 years old and still have a full head of hair. Alli makes the fat pass through you and that of course appears in the toilet. That’s the point. Otherwise it goes to your waistline. Most of these websites are trying to get you to switch from Alli to some other and much less effective treatment.


I understand i have been taking it for a year now i was 330lb now 287 i love it

Your Name

Do u work out while taking it?


hhhhhmmmmmm, Have just started using Alli, but have had no Bm movements, and think I may have had over the recommended fat allowance. Although not much over. Very concerned about the hair loss people are talking about. Is it very common. Any way only early days, so fingers crossed!good luck to every one elsesmile


I’ve been taking alli for about 2 weeks now and I haven’t had any bad toilet trips, I’ve just had really bad gas really smelly ones. Can anyone recommend anything for this?


Yes, Alli DID work. I lost a lot of weight gradually over 2 years. However, the last year or so I have purchased Alli, Orlistat, Xenical etc at great cost. It now has no effect whatsoever. I am assuming the ingredients have changed since a major re-call a few years ago. Such a shame, as was the only “safe” diet pill on the market.


I have been using Alli for several months now. This last bottle seems to have no effect. I opened one of the capsules and it is chunks of white stuff, instead of powder. It is like there is no Orlistat in them.
Sorry if this seems crass, but when the stuff is working, my BM’s float. Has anyone else gotten bad bottles??


Im 222lbs. I started Alli yesterday. 3 tablets with my meals which were moderatly fatty. Today i had pretty much the same semi unhealthy things but all Ive got is rumbly gurgling sounds in my belly and no urge for the toilet. Is this normal? Shall I wait a few more days…?

Stephen (Editor)

Hey, Alicia. Give a few days to see if there’s any change on that front. While you should eat healthily we can’t say if it because of your meal choices. Do you feel constipated?

Your Name

How much weight you lost? And how long it took you?


This page deserves more traffic. I saw it on 12 place in google search results. You should do some search engine optimization, if you need help, search in google: Oldome’s tips outsource the work


ive been taking for about a week now and I know I don’t eat a lot of fat during the day so the pills haven’t really done anything but last night I had prociiutto cheese pizza and It took almost 7 hours for me to finally go to the bathroom?? Shouldn’t the pill have worked quicker on such a fatty dinner??


But did you have an oily discharge?

Hi Christy,
It depends on how fast your metabolism is.


Your e-mail ad site says buy Alli, but when you go there, you don’t offer Alli. What the hey!


I have used Alli in the past and it really helped me lose weight and inches but now I cannot find it in ANY pharmacy store or discount stores such as Walgreen, WalMart, etc. Can anyone tell me where I can purchase more Alli??? Thanks in advance.


I found it at CVS behind the front counter (near the Nicorette). You have to ask the cashier to get it for you.

Your Namecathy ballenger

I have never tried the product. I am researching it. That is how I came across this site. The only place I have seen it on the shelves is Target.

HI Linda,
You can purchase more Alli through the official website. You’ll get 60 capsules.

Your Name

Walmart should have it in their pharmacy section with the protein bars and weight shakes.


you can find them at walmart but everything is online now

Maria Martinez

Hello, I thought this was a awesome blog. Thank you for sharing.


I been taking Alli or Xenical for past 12 years. When I started, I weighted 346 lbs. It took five years to lose 100 lbs. Currently weigh 228 lbs. Never put the weight back on. Never experienced any side effects until recently in past six months been losing my hair rapidly. Never thought it had anything to do with Alli until reading these blogs. It allows me to lose about 3 extra pounds per month when I am dieting. I did have embarrassing moments over the years from large unaware stains on seat of my pants. I stay with dark pants as much as possible. Learned how to avoid this after many years of use. Just ran out of Alli and will try to go without it for first time in 12 years to see what happen. Does hair grow back if you stop using it.

James Johnson

Hi, I thought this was a nice blog. Apreciate you sharing.


if i took 2 alli 3 times a day instead of 1 would it be ok

Hi Liz,
We recommend to follow the instructions that it says on the bottle. Taking it too often could negatively affect your body.

Your Name

what colour is the powder inside pls. I brought alli online 2years ago and lost much weight.i brought them again but this time they are not working

Candace (Editor)

This company actually addresses this problem on their official site and claim they have made no changes to the formula since 2007 and have maintained it’s original efficacy. Oddly several dieters say otherwise.

irene stohm

what if i took 4 instead of 3 by mistake

Hi Irene,
Taking an extra one by accident just once should not give you serious side effects but I would double check with your physician just in case.


Looking for info on taking Alli after bariatric surgery, Roux-en-Y gastric bypass. Has anyone tried this? I think extra vitamin supplements would offset the possible effects of malabsorption.


Take your vitimins people!!
