A diet product’s worth depends on whether it helps people lose weight. Let’s find out if the Advocare 24-Day Challenge works. Our in-depth review focused on the side effects, ingredients, scientific research and customer service quality. Furthermore, we sorted through hundreds of user comments from all over the web. Then we condensed and refined to give you the info you need.
What is the Advocare 24-Day Challenge?
First off, the Advocare 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 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. Individual supplements and the kit are sold on the official website. We found some customer testimonials and some products contain natural ingredients, but read on…
Steep Price – “Too Expensive?”
The first issue was Advocare 24-Day Challenge cost. “The actual price of the bundle is not listed on the website at all,” said our Research Editor. “However, we did find it on distributor websites such as Amazon, and it’s offered at $189 (plus $7.49 for shipping).”
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.”
One commented, “It is worth the investment in yourself.”
24-Day Challenge Reviews – “Positive or Negative?”
There are many complaints posted online about the Advocare 24-Day Challenge ingredients. 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 said, “No feeling of hunger. Doing well on this diet.”
Our research has proven that if there is an individual facet of a diet program that is bothersome, like negative customer comments, the likelihood of weight-loss for the long run is minimal because the client won’t stick around.  So, if Advocare 24-Day Challenge reviews are right and use 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 for 24 Day Challenge Advocare, 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. There is support for meal replacements as a means of reducing caloric intake.  We at DietSpotlight need to see documented scientific research that supports the weight-loss product, and in this case, we weren’t successful at linking branded Advocare products to proof, but there are tested ingredients shown to have positive effects on weight and metabolism.

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 feel comfortable recommending spending nearly $200 for Advocare 24-Day Challenge results that may not happen. There is no evidence that this program works or that it’s better than a traditional meal replacements program. 
If you want to get started dropping that weight today, we suggest you go with a weight-loss program or diet supplement that is backed by real science that won’t break your bank account.
Among the best products we’ve seen this year is one called Dietspotlight Burn. This supplement uses a combination of four ingredients with clinical research behind them showing they can help with metabolism and fat loss, so you lose the weight you want to lose. Plus, users are talking all over the web about the amazing changes they noticed.
They’re so confident that you’ll love Dietspotlight Burn that they’re offering a Special Trial Offer, which is a nice touch.

24-Day Challenge: What You Should Know
The 24 Day Challenge is a certain regimen to help people reach their weight loss goals in 24 days. This is a normal range for a challenge as some last a few days, like the 14 Day Açai Berry Cleanse, to a few weeks. It comes from the company, Avocare, who has been producing nutrition and health supplements for 17 years. Read this review to learn more about this program and its products to help you determine whether or not you want to use this to help you reach your weight loss goals.

List of Ingredients
Product Features of the 24-Day Challenge?
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.
Advantages of the 24-Day Challenge
- 24-Day Challenge helps to address burning calories while also taking in fewer overall.
Disadvantages of the 24-Day Challenge
- 24-Day Challenge seems to be focused on offering a MLM sales scheme as much as they are selling a product.
- We do not see the ingredient lists for any of these products.
- We do not know if there is a money back guarantee for these products.
- These products claim to be endorsed by celebrities, but we do not see any proof outside of the YouTube promo video.
- There are no free trials of this product.
The 24 Day Challenge seems solid, but many things people try to sell you do seem that way at first. Products promising weight loss over days should always be scrutinized, sort of like 7 Day Weight Loss Pill. 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. Aside from this product, you might be interested on one that is similar called 17 Day Diet which is a diet plan that focuses on dropping 10 pounds in the first 17 days.
The 24-Day Challenge is a weight-loss plan from Advocare. The first phase is a cleanse and the second is to fuel the body. There are multiple supplements in the line, including Herbal Cleanse System, OmegaPlex, Advocare Spark, MNS and Meal Replacement Shake. Complimentary products include Catalyst, ThermoPlus, Carb-Ease Plus and a series of workouts.

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.”

Advocare 24-Day Challenge Scientific Abstracts:
Arctium lappa (burdock) has been a traditional medicinal tool for hypertension, hepatitis, gout, and inflammatory disorders. Studies have shown that burdock roots contain anti-inflammatory, hepatoprotective, antiproliferative, and free radical scavenging activities. These hydroethanolic extracts were found to possess the strongest free radical scavenging activities. The dichloromethane extracts (from lappa root) had displayed antiproliferative traits against MCF-7, K562, and 786-0 human cancer cell lines. 
The potential for anti-cancer effects of ginger is very well documented and is due to the functional ingredients like school, gingerols, and parasols. These are all considered valuable elements that can prevent a broad range of cancers. It had been concluded for ginger, but some clarity is still needed to claim the correct efficacy. 
Studies based on the data which is available appear to be for beetroot as a powerful dietary source of health promoting agents as well as being a treatment for an array of pathological disorders. Beetroot’s immense anti-inflammatory, antioxidant and vascular-protective effects have been a demonstrated in detail by several in vivo and in-vitro studies using both human subjects and animals. In human trials, beetroot supplements have been said to decrease blood pressure, attenuate inflammation, avert oxidative stress, preserve endothelial functions and restore cerebrovascular hemodynamics. Several studies have also reported beetroot’s beneficial athletic performance capabilities. 
Verbal memory (VM) and visual memory (VsM) performance factors were better alongside larger concentrations of choline consumption in multivariable-adjusted models for verbal memory (average modification in neuropsychological factor per 1-unit change in choline = 0.60; 95% CI: 0.29, 0.91; P < 0.01). Isolated choline consumption was inversely related to –log-transformed white-matter hyperintensity (the average difference in log white-matter hyperintensity per 1-unit change in choline = −0.05; 95% CI: −0.10, −0.01; P = 0.02). It had been concluded that higher amounts of choline intake were related to improved cognitive performance while increased remote choline intake was associated with little to no white matter hyperintensity. 
There have been several in vitro studies involving multiple cell types which have shown beneficial effects when glycine is added. Glycine has also increased the health conditions of isolated perfused or stored organs. In vivo tests in animals have experimented with glycine as a protector molecule. At high amounts, glycine may cause toxic effects; there need to be more studies investigating the safe range of dosages of the amino acid as well as testing the pathways of administration.
