24 Day Challenge Review - Does This Weight-Loss System Actually Work? Are steep price and dieter complaints deal breakers?

Editor's Review: 3.5 / 5.0
24 Day Challenge Review

A diet product’s worth depends on whether it actually helps people lose weight. Let’s find out if the 24-Day Challenge really works. There has been plenty of discussion about this program for weight-loss, so we decided to write a detailed review, focusing closely on the side effects, ingredients, scientific research and customer service quality. We also sorted through countless user comments from all over the web. At this point we compacted all of the facts and feedback we found to give you the bottom line.

EDITOR'S TIP: Combine 24 Day Challenge with a proven fat burner such as Leptigen for better results.

What You Need To Know

First off, the 24-Day Challenge is a “comprehensive supplementation and nutrition program” that is suitable for people of all body types. The primary purpose of this challenge is to help you jumpstart your body so you can reach your weight-loss goals. This involves six different elements and a daily guide. These include Herbal Cleanse, AdvoCare Fiber, OmegaPlex, AdvoCare Spark, meal replacement shakes and MNS 3, C or E.

AdvoCare was founded back in 1993 and the 24-Day Challenge was released around 2013. The official website has some customer testimonials, as well as a helpful FAQ section to assist dieters, but read on…

Steep Price Tag – “Pay What?”

The first issue we came up with regarding the 24-Day Challenge results was the total cost. “The actual price of the 24-Day Challenge supplement bundle is not presented on the website at all. However, we did find it on distributor websites such as Amazon and it’s offered at $189 (plus $7.49 for shipping),” says our Research Editor.

One dieter stated, “I could have achieved my goals (like I have done many times before) without shelling out $200+.”

Another user offered, “Did not help at all! What a waste of money.”

The price tag didn’t seem to be a problem for others. As one buyer says, “Money well spent.”

Some dieters looked at it from a different side of things, “It is worth the investment in yourself.”

Others felt simply, “Overall a good price and a good program.”

Scroll below for one of the best products we’ve seen over the last year.

Dieter Complaints – “Not What Was Expected!”

There are many complaints posted online for the 24-Day Challenge. One customer commented, “I did not lose any weight. I did have more energy, but I also had headaches.”

According to another dieter, “Followed all the instructions. only lost 5 pound total.”

Where there are negative comments there are positive ones. A dieter who tried the challenge said, “It really worked well. I had lots of energy.”

Another buyer claimed, “No feeling of hunger. Doing well on this diet.”

Our research has proven that if there is a certain facet of a diet program or weight-loss pill that is very bothersome ( high cost, pills that make your jittery) the actual likelihood of fat loss for the long run is minimal. So, if the 24-Day Challenge does result in too many dieter complaints, this could be a major concern.

The Science – “Proven Effective?”

While there is “science” mentioned on the official website, we did not find any actual clinical studies. The website talks about “safe and effective ingredients,” but does not elaborate on how they are used for weight reduction. We at DietSpotlight need to see documented scientific research that supports the weight-loss product and in this case we weren’t successful.

The Bottom Line – Does the 24-Day Challenge Work?

So, are we ready to start losing weight with this one? First of all, it’s nice to see that this company has been around for many years. On the other hand, we would not recommend spending nearly $200 on the 24-Day Challenge supplements. There is really no evidence that this program works and there are plenty of customer complaints that say it doesn’t. Also, this diet program requires you to take a lot of pills every day.

If you really want to get started dropping more pounds of fat, then we suggest you go with a weight-loss program or diet supplement that is backed by real science and won’t break your bank account.

Among the best products we’ve seen in 2016 is one called Leptigen. This supplement uses a proprietary combination of four ingredients, which have been proven in published clinical studies to kick-start metabolism and encourage fat loss. Moreover, we haven’t found any customer complaints of harmful adverse effects and user comments posted online reveal people are seeing solid results.

Plus, we love the idea of Leptigen offering a Special Trial Offer, which is a good sign of confidence in the product.

List of Ingredients

Not applicable.

Product Features

The 24 Day Challenge begins with a cleanse/detox that lasts for the first 10 days of the program. The Max phase is the second phase of the program, and it lasts from days 11 to 24. The first phase is designed to detoxify the body to help increase absorbency, and a sugar free energy drink. The challenge uses a cleanse similar to 7 Day Detox. Basically, this can help you get rid of cravings and increase energy levels to combat the fatigue associated with detoxification. The Special K Challenge also requires you diet from a selection of foods and products. The second phase is designed to help you start the momentum, so you can increase energy levels to affect calories out, while steering the appetite away from cravings for sweets, and high carbs, to affect calories in. You will get more of the energy drink, as well as a meal replacement shakes. Some shakes may be protein shakes like Herbalife 24 Rebuild Strength. If you get the “plus plan” there are additional products to help feed lean muscle so you don’t lose it while you’re burning fat. There are forms and documents on the website that will help you, such as meal planning, etc. to help you stay accountable and support. There are several different pricing points, depending on how involved in selling the product to others you are—it is possible to sell enough to make enough income to cover the cost of your own supply.

The 24 Day Challenge seems solid, but many things people try to sell you do seem that way at first.

Without taking a closer look at the products themselves to see how they work and what their ingredients are, we cannot really comment on how effective they would be. This combined with the fact that they are trying to get you to start selling the product is a bit of a turn off for some people.

24 Day Challenge Ingredients:

We dug deep into the 24 Day Challenge ingredients to give you the details you need.

Advocare Spark

Advocare Spark contains Vitamin A, Vitamin B12, and Vitamin E. Other natural ingredients are added and vary depending on flavor. This product is used throughout the entire program.

What is it Supposed to Do?

Advocare Spark is supposed to enhance mental energy and focus.

Clinical Research

According to a study published in Nutrition Reviews, “Folate is a water-soluble B-vitamin and enzymatic cofactor that is necessary for the synthesis of purine and thymidine nucleotides and for the synthesis of methionine from homocysteine. Impairment of folate-mediated one-carbon metabolic pathways can result from B-vitamin deficiencies and/or single nucleotide polymorphisms, and increases risk for pathologies, including cancer and cardiovascular disease, and developmental anomalies including neural tube defects.”

Clinical research is an important part of the equation when it comes to choosing a diet supplement. You may want to take a look at a product like Leptigen, which is formulated with clinically tested ingredients.

Herbal Cleanse

This is used during the first phase of the program – days 1 through 10. It includes Herbal Cleanse, Probiotic Restore, and Advocare Fiber.

Clinical Research

According to a study published in The Lancet, “Lactobacillus GG [one of the most common probiotics] was effective in prevention of early atopic disease in children at high risk. Thus, gut microflora might be a hitherto unexplored source of natural immunomodulators and probiotics, for prevention of atopic disease.”

Advocare Fiber

This product is rich in fiber and provides 10 grams per serving.

What is it Supposed to Do?

It is supposed to support intestinal function and enhance nutrient absorption, while also providing a feeling of fullness that may help curb the appetite.

Clinical Research

According to a study published in Nutrition Reviews, “Individuals with high intakes of dietary fiber appear to be at significantly lower risk for developing coronary heart disease, stroke, hypertension, diabetes, obesity, and certain gastrointestinal diseases. Increasing fiber intake lowers blood pressure and serum cholesterol levels. Increased intake of soluble fiber improves glycemia and insulin sensitivity in non-diabetic and diabetic individuals. Fiber supplementation in obese individuals significantly enhances weight loss.”


This is also used during the cleanse phase of the diet, for the first 10 days. It is blend of omega 3 fatty acids.

What is it Supposed to Do?

Omega 3 fatty acids are essential for nerve, heart, muscle, skin, bone, and immune health.

    Are you kidding me…I assume that the people who are complaining didn’t do it correctly..I have coached about 25 people now and everyone of them have had great results with no side effects..

    Tell us your thoughts about 24 Day Challenge.I started the challenge 8 weeks ago and continue on the product. I have lost 48lbs. in 8 weeks and I eat what I want for lunch everyday after the challenge. I have tons of energy now. This is a very good product.

    I am going to starting the 24 day challenge I take Topamax for migraines
    I read that people were getting headaches from stuff that’s a concern to me should I take this product to my doctor first

    I LOVED ADVOCARE 24 DAY CHALLENGE. I lost a total of 20 pounds. I had so much energy and felt amazing. I am really wanting to do another challenge, however I have read some concerns about the high amounts of niacin. From what I have read, niacin is healthy for you in small amounts but can harm your liver and cause skin reactions in high amounts. However, the product did was it was advertised to do and was well worth the money. You must be willing to also follow the diet of complex carbs, fruits, veggies, and proteins. If I choose to get the challenge again, I will purchase an extra box of shakes so that I can use them if i do not have time to make a meal.



    If you follow a diet of complex carbs, fruit (limited), veggies, and lean proteins, and you exercise… why do you need to take all the supplemental crap? A healthy, low sugar diet and exercise = weight loss

    I started my 24 Day Challenge 4 days ago, and let me tell you that I feel great! I saw 5 friends of mine lose some weight and I was like wow these are not TV people or somebody trying to sell you a product. My wife and I are doing it and look forward to a healthier lifestyle. I see people complaining about the price, the way I see it is you blow $200 dollars on a weekend going out to eat and maybe drinking some drinks. If you can spend $200 on yourself to live a better lifestyle then dont even do the challenge. Also if $200 breaks your bank you need to worry about finding a better job,career ect. I will keep you posted on how the results are, one thing I can say its not easy. I was used to eating junk food alot.

    Are you allowed to “cheat” every now and then without big consequences? Are you allowed to have a glass of wine?


    Your Name

    you should limit your alcohol and sugar consumption while doing the Challenge. If you’re serious about getting results you shouldn’t “cheat”. You won’t be very successful if you cheat. It’s only 24 days…after that stick with moderation. As with any diet/nutrition plan, you get what you put in and you MUST exercise in addition to changing your eating habits. Good luck!

    I use to lose weight so easy then I turned 40. Ugh. I kept gaining little byuttle and none of my old trucks were working. I got the challenge from a friend and lost 13 lbs in 14 days. All my friends were asking what I was doing, of coarse. They wanted it also so I joined and became an accidental distributor.

    Since the beginning I’ve learned so much about this 22 yr company. The scientist and teams that develope their products. Athletes can safely use the performance line with testing positive for anything. That’s why Drew brees, Jason whiten, Richard froning and many more professionals use this. A company can pay anyone to say they use and like a product. These are non paid endorsers. They can use anything and chose Advocare. Great stuff!!


  • 9

    I have completed the 24 Day Challenge and are still enjoying many of the Advocare products. I have lost 20 lbs and have never felt better. I highly recommend the Challenge and the Company. While you do have an opportunity to offer the products to others or join for a discount memebership, it is not the main focus.


  • 10

    I was thinking about taking this product with my husband but I am a type 1 diabetic will this harm me if I did the challenge.



    I would consult your doctor for sure. I know people that are diabetics and did the challenge. The best advise would be from your doctors.

    I take medications will this effect me?



    Worked great. I am on med also

    I take siezure meds, Mobic for arthritis
    and thyroid med and nexium. Would that be a problem for me to take the 24 day



    My son (age 17, 6’5″ #202 now) has epilepsy and has been on it for 20 days now with no issues. He is down 13 pounds and has had no ill effects from the challenge.


  • 12

    I love what AdvoCare challenge has done for me. Any lifestyle change that improves your quality of life is a good thing. YES!


  • 13

    I’m doing the 24 day challenge right now. I’m not a distributor or anything like that. I was recommended by a friend who lost 12 lbs and his wife lost 9. I’m a full time college student and a part time waiter…so I gained about 30 pounds. I’m currently on day 4. All I know is that Ive had more energy than I have had in 4 months. I weighed this morning and I’m down 8 pounds. I don’t know how hard it will be to maintain the weight loss after I’m done with 24 days but I do know that I wouldn’t say that this isn’t meant to be a diet. It’s teaching me what to choose and how to eat throughout the day. It’s a lifestyle change. Hopefully I can stick with it. Good Luck to you and finding your own way to lose weight.



    I’m going to be starting the program in the next week or so. I’ve been told and read that you can continue using the product. Find an adviser/coach to help you through it, if you don’t already. But also from what I read you should have one. Good luck.

    I chose Advocare 24 day challenge for my weight lost, I lost 14 pounds, 6 1/2 inches around my waist and 3 inches from each thigh, I did not reach my complete goal of 30 lbs weight loss in 24 days, that’d just be unrealistic. I did however find a company that basically became a family, they aren’t focused on selling products and making money off of you. They’re focused on helping you reach your goal and feel better just like they did. I have witnessed many people say they want to lose weight, an Advocare team member start speaking with them about the program, the person says they’re not interested and the team member stops speaking about the program, why? Because they aren’t trying to push it on anyone.

    Advocare products are great, I love them. Since I did my challenge back in February, I have continued using the products, my energy levels are through the roof but most importantly to me: I feel great, I don’t feel bloated, I get off work everyday with tons of energy that I WANT to go burn at the gym. Another outstanding fact about Advocare is the fact the products are tested for banned-substances, products are sent to a lab to be tested for over 200 banned substance products, when they’re proven to contain zero banned substances, they become an “Informed Choice” products – its very reassuring to know I am not putting anything illegal or harmful in my body, only replacing the nutrients it needs.



  • 15

    I too am an Advocare distributor. I do not push products on people but when I get compliments regarding my weightloss, I share my story and say that Advocare might also be a program to help them get healthier and/or lose weight. One of the reasons I chose Advocare was because they are very transparent when it comes to the ingredients in their products; the website is bursting with information if you just look at it. Plus Advocare is quick to say that the success of their products depends on proper diet and eating choices. I also liked that Advocare distributors and advisors were very supportive of others that used the products whether you decide to sell them or not.



    Can we purchase and have shipped to Canada?



    Tell us your thoughts about 24 Day Challenge. you can call the company directly and order to have shipped to you. As far as signing up as a distributor, I believe that is in the works. I am on my 3rd 24 Day Challenge and LOVE IT!! I hope this helps.


  • 16

    All of the complete ingredient lists are easily accessible for every product in the 24 Day Challenge. You can go to any distributor’s page where it is sold and see a comprehensive ingredient list and nutritional information sticker. The products are all completely money back guaranteed. I am a distributor but just wanted to give you the correct info so that the right information is going out to people who may be interested. I am not trying to sell anything to you now or anyone else as I am not giving my distributor info. Hope this helps.


    Your Name

    The products are not completely money back guaranteed. I bought to big canisters of rehydrate instead of spark and they would not refund the money, they would only exchange. Luckily, I wanted an exchange anyway, but that was pretty lame and could have been a very costly mistake. [actually, the mistake was a dropdown box on their website]
