Isagenix Consumer Experience Survey
Researched reputable sources for real user opinions.

Isagenix was founded in April of 2002, and is a multi-level marketing business that aims to sign individuals up to be brand ambassadors. Based out of Chandler, AZ, they sell nutritional products such as protein shakes, weight loss supplements, diet snacks, and meals. When calling into their support line, I was routed through three different systems to simply talk to one person about some general questions. This was a long process to simply talk to someone real, so I would try to get your questions answered in one shot versus having to call in multiple times. When they try to sell customers on becoming millionaires by selling their product, I already have a gut feeling that this is too good to be true.* To see the Isagenix program reviewed by the Better Business Bureau click here for more insight.

Do Dieters Lose Weight on the Isagenix Diet?

When dealing with multi-level marketing platforms, it can be hard to get a straight answer because it’s difficult to distinguish between who was a rep trying to make their way up the pyramid, and who was a genuine customer with feedback. The Isagenix website is only going to post fabulous reviews, so I searched other outlets for raw feedback.*There was a more negative outcome with customer reviews on the internet, when compared to the actual website. Some people said it was a complete waste of money, while there were only a select few who saw results. Once again, it is hard to distinguish who is a rep and who is not. There is no real scientific evidence behind the actual products themselves on the website, more or less there is information on how to use their products.

We have found some reviews available outside the official or distributor sites:

“Please don’t waste your money on this product! I was super excited when I heard about this product, and how well it supposedly worked. I followed the directions to make my first shake, and the taste was terrible! It doesn’t taste like chocolate at all. It is very chalky and has a texture like cake batter. Over the next week I tried adding peanut butter and fruit, but nothing made it taste better. Also, it didn’t keep me feeling full either, each day that I took the shake, I would end up with a bad headache every afternoon.” Jessica

“I got this because the review looked good. I have tried other mixes and couldn’t use them because of their content and me having a bad reaction. I bought this and tried it for almost 60 day which is what most nutritionist would suggest for something to truly have a chance to work as it should. First let me say that is taste horrible. I tried to add fruit to the mix and all and I still had a hard time drinking. Also it didn’t mix well no matter what temp water I used. I wish I could return after this epic fail. I didn’t have a weight loss success and it was not satisfying to my appetite at all. Would not recommend to anyone. Not worth the money at all.” Denise Dameron

As far as scientific backing and clinical trials, the company does not make it easy to find out the real details behind the science of their product. There is no tab on their website talking about the development of the product. They provided the only clinical study I could find in small print on their 22-page booklet on how to take their product:

All of the descriptions are vague and full of fluff. The transparency is not there, when taking a deeper dive into what you will be consuming. Good reviews can simply be purchased, which has me thinking that this mega company has invested their money in trying to pull popularity through reviews on their website.

Is The Isagenix Diet Easy To Follow?

No, it is not easy to follow.* There are many different products that Isagenix offers, but the most popular package to buy is the 30-day Cleansing and Fat Burning System. You are required to replace one normal meal with one Isalean shake, accompanied with a 400-600 calorie diet to start out on the “shake days.”* On the cleanse days, they were unclear whether or not you could eat. I am assuming you cannot, so you are required to take four cleanse servings along with four snacks for the day. In the 30-day system you are allowed 26 “Shake Days” and four “Cleanse Days.”* Because this program promotes intermittent fasting, you may feel light-headed, and it can do long-term damage to your metabolism.


You can purchase Isagenix on multiple different sites such as Amazon, the Isagenix site, and Ebay. I believe this company is just another multi-level marketing company that offers nutritional supplements with little to no benefits for your overall health. I would call them a multi-level marketing scam myself, because of the inaccurate reviews on their website versus the rest of the internet. The cost of the 30-day system is $350.00, which is over-the-top expensive, when there are red flags present. I do not feel that this diet program is worth the investment or the time!*

  • Michelle Louise Jara

    The lady did do her research. Perhaps you are an ambassador. As a personal trainer, a professional in the business, I can assure you any weight you lose on this program you will NOT keep off. Eating a well balanced meal and exercising 4 days a week (with a physical fitness program designed to target your specific goals and problem areas) you will have continued life success with fitness. In addition, a great diet to try is the ZONE diet or weight watchers. They allow you to eat a variety of foods that are tasty and you do not have to supplement at all.

  • Lisa V

    Isagenix must pay all of these people that write these extensive testimonials protecting the brand. The fact is that the shakes are disgusting, and for anyone to try and convince people otherwise is deceptive and dishonest.

  • Taraveah

    There are a lot of products that are going to do the very same thing and cost a whole lot less. I would do a lot of research before investing that much money. In addition, based on most of the comments, it isn’t the shake that is making the difference, rather clean eating. While the shake has a lot of stellar ingredients, it also has a lot of sugar (fructose) and sodium in it.

  • Patty Slocumb

    Isagenix is amazing. It is saving my life! It’s about supplementing a healthy way of living. It’s a lifestyle and NOT a diet. If you can’t give up eating like crap and you can’t begin working out to take care of your body…don’t blame somebody else. If you are looking for a miracle diet that does all the work for you while you sit on your backside then of course it won’t work! Take charge of your life and don’t expect something or someone else to do it for you.

  • Rebecca Cagle

    I use Isagenix. It is the only thing I could find that helped me. Before I started using it I felt nutritionally starved even though I was eating a good diet. It is real nutrition without toxic ingredients. The 30 day system only costs $269 not $350 as stated above. I use a maintenance plan of Isagenix products and it costs me about $185 per month. That money just comes out of my food budget replacing other foods I had been eating. Isagenix is the best thing I do for my overall health. I got my life back using Isagenix. I have energy and feel great! Isagenix is a godsend! I highly recommend it!

    • Michelle Louise Jara

      A great 30 day system that cost nothing is to simply just eliminate sweets from your body. As a personal trainer I can assure you these fad diets are extremely damaging to your metabolism. Once you stop…you are done for.

  • Chris

    I have been using Isagenix since November 1 and have dropped 40 lbs and 2 pants sizes. I think a lot of the people that post negativity on here just do it for the fun or sparring part of it. Am I really hungry some days, sure. Do I eat better and eat less, yes. Do I cheat at times like I am going to in about and hour, yes. The shakes took a bit of getting used to but are otherwise pretty good. I mix fruit in mine and peanut butter powder to add flavor. I also have more energy, I have been sleeping better and my hips and knees feel great. I don’t outwardly market this (maybe I should) but I have been having a lot of people come to me inquiring because of my results. It works for me and I feel great. I would suggest if starting that you partner up with someone. My wife and I are doing it together and try to hold each other accountable. That has made it a lot easier. Once you get past the first 2 weeks it is pretty easy. Also makes packing a lunch easier and less time consuming.

  • Michelle

    I haven’t used this program in years. However while I was on it I quit drinking coffee and smoking without even realizing it until days later. This product works great. Also those of you that were still hungry that normal it takes most people 3-5 days to get used to eating less plus if your the type to eat a lot of processed and junk food then yes you’ll feel like your starving to death. It does get easier though. I honestly felt great using this product more energy and yes I did loose weight too.

  • Darryl F. Stewardson

    Your review is completely one sided, you have not interviewed one person who loves it and has positive results. further you did not conclude with any of the scientific studies it’s just your opinion, which is lacking at best!

  • Gwen James Ryans

    Ive used Isagenix 2 times now! and I love it… I’m currently on a Nine day cleanse and on day 7, I was 136lbs to start and now currently sitting at 124lbs with 2 days to go… Ive always lost weight and maintained the weight loss after, yes you will get light headaches first few days if your a coffee drinker, Not from the shake itself! lol as you can not drink coffee as this is a cleanse, adding fruit and PB to your shake wont help you loose weight either there not meant for that, the shake is designed to help you loose weight and feel full longer, if your adding fruit and PB of course you’ll end up hungry! the surger in the fruit alone will trigger hunger!
    the Dutch chocolate is my favorite, I don’t like the vanilla I bought both flavors and mixed one scoop of both added ice and water to the blender and it was yummy, thick like a shake..
    people complaining about this Isagenix cleanse, are people that have a taste for junk food, or course its not going to taste like a Mc D’s shake! its a cleanse
    I found it very easy to follow, 2 shake days to start, that’s 3 shakes a day and then 2 cleanse days ( no food) then 3 shake days, the 2 days no food.. then your done… how hard is that…lol
    bottom line it works! did for me.. you just have to have willpower and follow it properly , no adding anything…

  • cjus2473

    you are correct – I mix the vanilla/strawberry (I cannot eat chocolate) and it’s fine…I find that people who hate the taste think it should taste like a Wendy’s chocolate freeze…it does not…but it is not bad…the program works if you stay with it…i find people who get off the program and eat like they used to (that was me and I finally made the decision that a pint of Ben and Jerry’s during stressful times was not the answer), bitch and say the program does not work. But then I have a step-mother who does not eat sweats, has never liked junk food, rarely eats meat and has been a normal weight all her life…so she feels everyone should eat healthy…it is a matter of choice….but you are very correct…you will lose the weight if you follow the rules

  • cjus2473

    Wow – this is biased…I went on the program 1 year ago…if you stay on it, the worst you will do is learn to eat correctly…the rest is up to you. The shakes are good…I have one for breakfast and dinner, with 2 snacks which consist of 150 calories each; i have a dinner that is between 400 and 600 calories…you cannot have sugar – you can have stivia; you can only eat fish, chicken and turkey; the only fruit you can have on the strict 30 days is green apples – Granny Smith; the cleanse days are not that difficult but not my favorite – they consist of drinking 4x a day – you are not supposed to eat during the cleanse days. You eat the program for 30 days, and during that time, you have 4 days of cleanse back to back…in one month i lost almost 40 inches all over and 11 pounds and kept losing…if you go back to eating the way you did before, you will gain it back – no matter what program you go on. What did this program do for me…well, you learn to eat healthy food. Does Ezekiel bread taste like Mrs Bairds – no; is it more expensive – yes. But I found I did not grocery shop as often as I did prior to the plan; my backaches, joint pain, acid re-flux went away – I tested this to see if it was the program and if I consume any regular sugar, cookies, cake, etc. my acid re-flux will come back in a flash. My blood pressure went back to normal in 3 months, my cholesterol dropped to normal. So the take away is – if you don’t want to spend the money – and it is expensive – around $250-$325 for the 30 days package and you make your own meals, they just give up dairy, sugar, packaged food, processed flood, fast food, meat and eat “clean”…limit your intake to 1200 calories and if you exercise, half the amount of calories you burn per day and add that to the 1200 calories and you will lose weight. I frankly sleep better, have more energy – and I am 68 years old. So like anything else – you need to maintain to keep the weight off. I have tried Jenny Craig, Atkins, Weight Watchers (which is now going to shakes) and found that Weight Watchers is the next best thing. You really don’t have to exercise with Isogenics but it helps. You will loose visceral fat and inches. I do not sell the program; my friend does and got me started. I am not a sales person and the folks I work with could not afford to do the program. But I have never been pressured, and really don’t know what the person who wrote this article is talking about. You just need to monitor yourself and not get in to the trap of comparing yourself with others as there are a lot of 40 and under folks who have 20 pounds to lose and seem to do it in weeks…then there are others who have lost 100 and more pounds and they are inspiring. You will also find that you don’t appear to have the excess skin doing this when losing a lot of weight. So hope this helps

  • Mike Perry

    The shakes taste HORRIBLE!!! For the cost of the program yiu would expect it to taste decent.

    • Darryl F. Stewardson

      That’s your opinion, I and hundreds of thousands think the opposite. They taste amazing and are real food and work.

    • Patty Slocumb

      I LOVE the shakes!! The vanilla is awesome by itself and you can tweak it to taste like a ton of different flavors!

  • Lucy Caves

    My friend convinced me i HAVE to try it. She is a distributor. I felt bad to say “no”. So I caved in and purchased at a “special” friend’s price (not so friendly for my pocket). Anyways, I felt like i was starving, shakes tasted horrible and I simply didn’t have it in me to tell her it is a HORRIBLE product why is she selling it???Now, every time we are in a company of other people I have to walk away when she tries to convince other people to try. I think she has been brainwashed by the promises she can make money with it. Would not recommend this. Sorry Brinda :O

  • Roxy

    I was invited to the group of people on Facebook (closed group) and they have tried talking me into how “wonderful” this product is. People that buy into this bullshit need to check their heads. How can you believe a product that entrusts people with no medical or health background to sell “nutritional” supplements and shakes. They have no idea what they are talking about. This business model is disgusting and most of the reviews you find online are posted by distributors. I am not lying when I say there are tens of thousands of them. Just the site I was invited to had over 5000 distributors and they all fight over who will bring more customers as this is an MLM type of company. The more people you recruit the more you get paid. Would never trust to buy this sort of product. Plus I have heard it tastes gross too.

    • Darryl F. Stewardson

      Wrong! There are tons of medical and health people on the scientific board product development and representing it. The business model is far from disgusting, if you had half a brain you’d realize that but you’ve decided to trash rather than try.

  • Mary Cole

    I am never going a day without these products. I have tried just about every weight loss product/scheme out there with no lasting results to speak of. I started Isagenix August of 2013 and at 55 I feel better than I have in 20 years. For me this is not a diet but a beautiful lifestyle, for me weight loss stopped being the main thing long before the end of my first 30 days on these products. While I can’t say Isagenix will cure or prevent illness I can say,, before I couldn’t sleep now I do, before I had severe joint pain and now I don’t, before I was exhausted and bitter, now I have more energy than day and I’m joyful again. These products are free of GMOs and artificial sweeteners pure and natural. It is very difficult to get the equivalent in nutrients from our food sources now, they have been so genetically altered with GMOs and pesticides. And as far as costs, well this is my health care and we all now how expense being sick costs, I have also save a small fortune giving up diet sodas, expensive coffees and Rx drugs I needed to sleep, hormone balance and pain management.

  • Brooke

    I have been doing Isagenix since August. I have found two things to be very true 1) if you stop using the product you gain your weight back fast and more than you originally had and 2)the corporation itself is a glorified pyramid scheme set up to make you spend money. Whenever I tried to change or alter my autoship, Isagenix website would not allow me to do so. I couldn’t even delete my OWN credit card information! This morning I received a shipment I did not authorize. I called Isagenix and cancelled my membership. This was the ONLY way I could alter my account. Also, the so-called sponsors are trained to cater to the members who are SELLING the product, not just those of us who want to try and lose weight without having to push a product on someone else. It is like a cult.

    • Angela

      Brook sorry you had a bad experience, not all teams are built to just push the product. Many of us are actually there to be a support system for people like you who want to lose weight. Also the fact is that with many systems that people use to lose weight they will gain their weight back in no time and even then some. Isagenix should be used as a tool to learn a new healthy life style to not go back to old habits of eating. I do hope you found a system that can support you on your journey to health and happiness. Sincerely Angela

  • momofsix

    Hi, I just started this two days ago. So far so good…however this is pricey and doesn’t have the best flavor. Do comparable products exist?

    • Darryl F. Stewardson

      You are replacing meals so you don’t add it to your food costs, it’s in replacement of. It pays for itself.

      • Taraveah

        pfft. Not at a cost of $300

    • Patty Slocumb

      Try the vanilla and add a few blueberries or cinnamon or whatever you love. Adding a little fresh fruit will not harm the results and will help keep you motivated. With just a little bit of tweaking you can make it any flavor you love. Don’t give up 🙂

    • Taraveah

      Yes, there are tons of comparable products. It just takes some time and research, but they are most definitely available and some much, much better.

  • Nancy Griffin

    I have done diet after diet after diet.. the reason that I tried this one was due to my arthritis that was causing so much inflammation that I was taking meds and injections all the time and still in pain. What a great decision I made! I’m off all my meds, I’ve lost 30 lbs and average 150 per month. It may seem expensive to some but per meal it is not bad at all plus I eliminated nsaids and steroids which is amazing!

  • Margit Willems

    Hi everyone, just like Carol, I too am with Isagenix and want to correct a few misconceptions about the products. First and foremost, Isagenix is a meal replacement. Anyone who has read up on Isagenix is familiar that the product(s) are sold under three different categories–weight loss, healthy aging, and high performance. Therefore, it is important to look at what your goals are. IsaLean, the product that is pretty much the backbone of all three, is a great high quality meal replacement that gives you the nutrients your body needs on a per meal basis. While I originally started out with Isagenix to find out if the products are an option for me to use as a breakfast replacement–breakfast has always been a challenge for me, I actually started to lose weight. Hence, I continued with Isagenix and lost over the period of three months 20 pounds and two dress sizes, without the strict plan as described above. I replaced one meal a day, used the fiber snacks for when I needed a quick pick-up in the afternoon, but ate regular, healthful meals for lunch and dinner. As for gaining the weight if you stop really depends on your overall eating habits. I was off of the product for several months due to an emergency in Europe and didn’t have any problems. I recently went back on Isagenix not so much to lose the last few pounds I want to release, but because of a) the high quality of the product, b) the ease to eat a nutrition meal when I am out and about, and c) to help manage stress. I also want to add, I have lactose and gluten intolerance without any reactions–even the regular shakes. Yes, there are cheaper shakes etc out there, but the taste and quality are not the same. For less than $3.00 a meal, I know what I get .

    • Judy Nolan Gallagher

      When you continued did you still just do the breakfast replacement or did you go to the full 30 day cleanse?

  • Carol

    I too am with Isagenix. In my first 30 days, I lost 12 lbs and 26 inches..lost the weight and inches in the places that I wanted to release. No other “diet” has done this for me and I feel better now than I have felt in over a year. My ability to handle the stressers in my life are much much more easily handled. It is not expensive if you look at the amount of junk food and convenience food that people eat everyday. Heck for one value meal at McDonalds most wouldn’t bat an eye to spend $6 or $7 a meal…we are a lot less than that per meal and WE are putting GOOD nutrirition in our body..not a bunch of grease that is going to build up around our heart.

  • Scott Gee

    Geesh – just download the free app Lose it!, eat real food, slowly lose weight, and enjoy life. And there is absolutely nothing “cleansing” about Isagenix or any other diet. Eat less and your body “cleanses” itself, lol

    • Deanna Eiting

      Scott , as a RN and health coach I felt compelled to comment. While it is true eating real food is of the upmost importance, the availability of said “real food” is difficult. Its generally blasted with pesticides, herbicides and other cides. If you werent raised on an organic farm then you must cleanse the body. Colon, liver, and cellular detoxification IS necessary. Due to the fact that our environment has radically changed we are all toxic. Our cells are the building blocks of our bodies and they too get overloaded. Just look at the average american. When the cells and liver and colon are overloaded with toxins they get locked away in our fat cells and thus the fat cells expand! YOU Can not just eat better these days and hope for better health. The MDS and research team at Isagenix have painstakingly shown this to be true. Let it be known I am not currently a distributor. I have been looking for a solution or supplementalbregimen for my clients that gives them superior nutraceuticals to augment a healthy lifestyle. I have read numerous studies and will becomee my own guinea pig with Isagenix soon. And as far as cost.. as an RN who also worked for an insurance company I assure you that the cost in the long run far outweighs a couple hundred bucks of supplements monthly. Dont be fooled to think it wont happen to you (general public ).. 2/3 of americans have chronic disease that will with a high degree of statistical probability give them serious problems. Not every nutraceutical company is in this game for greed! Some really want to help people live better lives. And if they can make a good living helping others qchieve the same then more power to them. In fact, robert Kiyosaki and donald trump both agree that MLMS beat the hell out of working for corporate america. JUST A THOUGHT!

    • Darryl F. Stewardson

      It is real food.

    • Taraveah

      So true Scott Grim. Darryl F. Stewardson must be a distributor. Good for him, but I have gone through the ingredients of this shake and while there are a lot of good ingredients there is also a lot of sodium and sugar (fructose), and calories!

  • Fran Tellor

    I have been on the Isagenix diet plan for about 3 weeks and have lost about 15 pounds and 22 inches. I lost 8 inches in my abdomen- the bad fat that is really bad for my health. It isn’t as expensive as your review states. I paid less than $300 for a 30 day supply and it is the first diet that I could actually see the major decrease in the area I needed most. I’ve also learned to avoid carbs and no longer crave them or want them. I was a sweets junkie before. I have not been hungry at all on this diet and I have lots of energy. It is a cleansing diet, so because the toxins are out of my system I feel better and my skin looks healthier.

    • Elizabeth

      Fran Tellor: I am going to order my 30 day supply this weekend, have you continued to still lose the weight? How effective is it 4 months later?

      • Ashley Laws Fletcher

        Hi Elizabeth! Have you ordered your pack yet? If not, I’d be glad to help you. I have been doing Isagenix since mid-July and continue to lose weight, but I am still doing the shakes 2x/day.

  • Cindy

    I absolutely LOVE this product! It is the only diet program that has worked for me n I have kept off the weight while stuck in bed recovering from surgeries! I only have been doing 1-3 shakes a week. I lost my goal weight plus inches I never thought I would lose. The price is not $500 for a 30 day program so where they got there info….
    I take the active ageless vitamins n am super pleased w my health results!
    Its like any other. Product out there. But this one by far is the best!
