LeptiLean Review - Does This Weight-Loss Supplement Really Work? Are side effects and ineffectiveness deal breakers?

Editor's Review: 3.5 / 5.0
LeptiLean Review

LeptiLean company employees, have you ever taken your own product? We decided to take a closer look at ingredients, side effects, clinical research and customer support. Additionally, we examined hundreds of customer comments and reviews. Then, we summarized and refined to give you the info you need.

EDITOR'S TIP: Substitute LeptiLean with a proven fat burner such as Leptigen for better results.

What is LeptiLean?

First off, LeptiLean is a weight-management supplement containing gum Arabic, guar gum, locust bean gum, pomegranate extract, blue algae, beta-carotene, naringin, N-Oleoyl-PE, egcg and cat’s claw. The recommended serving is two capsules per day, a minimum of 45 minutes before a meal, supposedly helping you lose weight. One of the benefits is the product doesn’t contain stimulants.

There’s no mention of when LeptiLean was first introduced, but the makers, Advocare, have been in business since 1993. You can purchase the supplement through the official website and trusted retailers. We like the longevity of the operation and the low price, but read on…

Side Effects – “Not Good?”

The first concern was the occurrence of LeptiLean side effects. “When a supplement contains some natural ingredients, one expects to feel better,” said our Research Editor. “But, if customers start talking about adverse reactions, this could become concerning.”

“It gives me heartburn. Was not having problems before,” stated a customer.

“I never finished the bottle though due to it making me a little too jittery,” reported another.

The effects some customers experienced weren’t necessarily negative. “A product that suppresses appetite successfully and doesn’t make you jittery,” commented a consumer.

Ineffectiveness – “Not Seeing Results?”

According to customer reviews on the web, LeptiLean ingredients didn’t help users lose the weight. “Absolutely did not feel any difference,” said a user.

“It worked ok for about 2 weeks, then I was hungry all the time and couldn’t stay awake,” reported a dieter.

“Didn’t work at all. I took the whole bottle as recommended and no results,” said another.

While some customers didn’t notice results, others reported seeing some changes in their weight. “I take 2 LeptiLean 45 minutes before dinner and it suppresses my hunger so I do not over eat,” commented a user.

“I’ve only been taking this product 3 days and I’ve lost weight,” said another.

We’re research countless supplements and have found that all it takes is something problematic, like a formula not producing results, could limit the chances of long-term success. If LeptiLean doesn’t help you lose weight, there are concerns.

The Science – “Any Studies?”

After taking a closer look at the official website, we found the company offered products details, but doesn’t offer clinical research showing the supplement helps with weight-loss. We did find studies about ecgc, the active ingredient in green tea, but the finding don’t relate to this formula. At DietSpotlight, science-based facts are imperative. We become hesitant about it if there’s none.

The Bottom Line – Does LeptiLean Work?

Before you place your order, hear our final thoughts on LeptiLean. Well, we like that we found some favorable customer comments and it includes a few natural ingredients, but we’re skeptical about this one because there’s no research showing the supplement helps you lose weight. We’re also concerned because customers are reporting the product doesn’t work and they’ve experienced negative side effects.

If you want to lose those extra pounds, we suggest going with a supplement containing some clinically-tested ingredients, shown to work and no mention of adverse reactions.

Among the best supplements we’ve researched in 2016 is one called Leptigen. The product contains some clinically-tested ingredients and has been shown to accelerate metabolism and ignite fat loss – keys to you losing weight. Customers are seeing great results and no one is talking about negative side effects.

Also, the company behind Leptigen is so confident in their supplement, they’re offering customers a Special Trial Offer, a great decision.

What You Should Know

Leptilean is a weight loss supplement by Advocare that supports a feeling of fullness while boosting metabolism to increase weight loss. There are many products on the market making these claims and the ingredient list always tells the true story. We do know from a quick look at the ingredient list that EGCG is the only proven weight loss ingredient in the supplement. That is a negative from the start.

The official website for Leptilean from Advocare sells the product directly for $45.95 per 30-day supply. We found customer service contact information, but there are no testimonials listed in the product description.

List of Ingredients

Vitamin A, Biotin, LeptiCore, Naringin Extract, PhosphoLean, N-Oleoyl-PE and EGCG and Cat’s Claw Bark.

Product Features

LeptiCore is not described in detail on the Leptilean website, but we found an official website for the ingredient. According to that product description, Leptilean supports healthy leptin levels with plant polysaccharides, beta-carotene and algae. This is the ingredient that reduces hunger, according to the LeptiCore website. Several clinical studies are listed to support LeptiCore claims, but all of the studies support leptin not LeptiCore.

Naringin is found in grapefruits. This substance is what causes grapefruits to have a bitter flavor. It is listed as a common sweetener not a weight loss product. PhosphoLean is another branded ingredient with a brief explanation on the official website. PhosphoLean is the source of EGCG. EGCG is proven to increase metabolism, but we have no idea how much EGCG the ingredient supplies. Cat’s claw is used as a natural immune booster. We found no evidence that this ingredient will boost weight loss or metabolism.

The ingredient list for Leptilean lacks support from clinically proven ingredients. We like the fact that Advocare includes a source of EGCG, but why that source is a branded ingredient and not green tea we have no idea. There is no evidence that this product will increase leptin levels, reduce appetite or boost metabolism enough to spark weight loss.

  • All ingredients are found on the official website.
  • EGCG is proven to boost metabolism.
  • The price is comparable to other fat burners and appetite suppressants.


  • Only one ingredient is proven to have an effect on weight loss.
  • Two ingredients are branded with specific ingredients never revealed.


Leptilean is just a letdown from all sides. The ingredient list does not support weight loss claims. LeptiCore uses leptin research to support ingredient effects and no testimonials are available on any site related to this product. Dieters would likely see a better benefit from taking a green tea supplement every day and drinking strong coffee.

    I’m concerned about it giving me extreme heartburn. Was not having problems before. I do like the results but have to stop using it I’m actually about to finish first bottle and realized this could be my problem



    I am glad I saw your post, I get extreme indigestion/heartburn as well. I can’t eat anything and have actually had to throw up to get the “fullness” feeling out of my throat.

    LeptiLean is one of my favorite Advocare products. I take 2 LeptiLean 45 minutes before and it suppresses my hunger so I do not over eat at dinner and it keeps me feeling full all evening so I do NO late night snacking anymore. Advocare has been amazing for me with their supplements, light exercising and eating healthier I have taken off 80 pounds in 7 months. Nothing has worked for me like Advocare totally amazing.



    Kelli ok so you take 2 pills at once ?
