Gaia Herbs Diet Slim Review - Does This Weight Loss Product Actually Work? Are fad diet ingredients and customer complaints deal breakers?

Editor's Review: 3.5 / 5.0

gaia-herbs-diet-slim-product-imageAs you may know, there has been a lot of buzz about Gaia Herbs Diet Slim, so we took the time to create a detailed review, examining the ingredients, side effects, clinical studies and level of customer service. We additionally took a close look at dozens of user comments and dieter reviews posted online. Finally, we condensed the facts and feedback we found in order to give you the info you need.

EDITOR'S TIP: Substitute Gaia Herbs Diet Slim with a proven fat burner such as Leptigen for better results.

What You Need To Know

Gaia Herbs Diet Slim is intended to promote healthy body weight. More specifically, this supplement boosts energy levels and supports healthy thermogenic response, which means more calories are burned. You simply take one capsule three times a day, in between meals. The important ingredients used in this supplement include; Yohimbe, Turmeric, Green Tea, Ginger, Coleus Forskohlii, Bladderwrack and Black Elderberry. There is no special diet plan recommended with Gaia Herbs Diet Slim capsules.

This weight loss supplement was released in 2012. It contains antioxidants to help reduce damage from free radicals. This product is 100 percent vegan and it’s fine for people of all body types, but read on…

Fad Diet Ingredients

“We immediately noticed that Gaia Herbs Diet Slim uses Turmeric and Ginger to help boost the metabolism. However, like many natural herbs used in today’s diet pills, these ingredients have not been proven to aid with weight loss,” says our research editor.

One customer stated, “Diet Slim did not do a thing for me.”

According to another user, “It didn’t work at all for me. Don’t waste your time with this product. If I could have given NO STARS as my rating I would’ve.”

Customer Complaints – Not Good!

It’s always important to check out dieter reviews and user comments posted online, and unfortunately we found some complaints about Gaia Herbs Diet Slim. In fact, one user said, “Maybe it was just me and being sensitive to the ingredients, but it made my heart race and made me anxious….Stopped taking right away and tossed it into the trash.”

Another customer complained, “Directions are to take on empty stomach, but that tears mine up.”

After doing plenty of research, we have come to the conclusion that if there is one facet of a weight loss pill or diet product that is quite problematic (too many user complaints, fad diet ingredients, high cost) the probability of long-term weight loss results is pretty low. Therefore if Gaia Herbs Diet Slim does result in a lot of user complaints, this could be a serious dilemma.

The Science

No real science is provided to support Gaia Herbs Diet Slim as an effective weight loss aid. While the company website emphasizes that this product is vegan and the ingredients are natural, there is no proof that it actually assists with weight reduction. Here at DietSpotlight we must see published clinical research that supports the diet product and its ingredients or we simply see a red flag.

The Bottom Line

We appreciate that Gaia Herbs Diet Slim is made with natural ingredients and provides some antioxidant protection. On the other hand, we would not recommend this supplement for long-term weight management. After all, it contains fad weight loss ingredients that are not backed by any clinical trial evidence. Furthermore, we found numerous user complaints that Gaia Herbs Diet Slim does nothing at all.

If you need to melt off the pounds at a faster pace, we recommend you select a weight loss formula that does not use fad diet ingredients, is backed by science and sells for a reasonable price.

One of the top fat-loss products we’ve seen in 2015 is Leptigen. This diet supplement uses a proprietary blend of four ingredients, which have been shown in documented scientific studies to help ignite metabolism and encourage fat loss. Moreover, we can’t find any complaints of negative side effects and dieter comments found online express people are seeing excellent results.

Also, the makers of Leptigen are so confident in their product they’re offering a special trial offer, which is a good sign.

Gaia Herbs Diet Slim claims to force the body into fat metabolization mode instead of fat storage mode. This is the aim of all fat burners, but few contain proven ingredients that work as claimed. We found the Gaia Herbs Diet Slim for sale on a trusted third-party website. All ingredients are listed on the website and several carry the threat of negative side effects.

List of Ingredients

Garcinia Fruit Rind, Green Tea Leaf, Coleus Root, Turmeric Rhizome, Elder Berry, Yohimbe Bark, Bitter Orange Peel, Gymnema Leaf, Bladderwrack Fronds, Ginger Rhizome.

Product Features

Garcinia fruit rind is garcinia cambogia. This ingredient was considered safe for use in fat burning supplements until reports of liver damage hit the Food and Drug Administration. The FDA suggested that the Hydroxycut company pull products with the offending ingredient from the shelves of vitamin stores and online shops. When the products were reintroduced, they no longer contained garcinia cambogia.

Green tea leaf is a good weight loss ingredient. There are many clinical trials supporting weight loss and other health benefits related to green tea. Yohimbe bark is a stimulant. Stimulants are commonly used to increase how many calories the body burns, or metabolism. Bitter orange peel is a second stimulant. Combining stimulants can lead to dangerous side effects, including racing heart and hypertension.

Bladderwrack is a diuretic. Dieters should never take a diuretic to lose weight. This could cause dehydration, potassium loss and cramping. With extended use, diuretics have been linked to death.

There is a warning associated with Gaia Herbs Diet Slim. Dieters with high blood pressure, bipolar disorder and various diseases should not take this supplement. Dieter with kidney disease should never take a diuretic because it increases the stress on the kidneys.

Gaia Herbs Diet Slim sells for less than $20 a bottle. This price is lower than the average diet pill. Just because the price is lower does not mean the dieter should jump on the supplement.

  • Ingredients are listed online.
  • The price is lower than other fat burners.


  • The supplement contains a diuretic.
  • The fat burning ingredient, garcinia cambogia, may cause liver damage.
  • Not enough green tea in one serving.


Gaia Herbs Diet Slim is just another supplement making extraordinary claims. The ingredient list contains a couple good ingredients, like green tea, but that is not enough to promote healthy weight loss. The price is lower than average, which could drive the dieter to take a chance on Gaia Herbs. Diet pills are not something to chance as some ingredients can cause negative side effects. We suggest choosing a diet pill with testimonials, before pictures, after pictures and clinical evidence.
