Slenderiiz Review – Is This Weight Loss Supplement Effective?

Ingredient Analysis

Analyzing the ingredients of a supplement is a key step that can help you safely establish how effective the formulation would work.

Slenderiiz Supplement Facts

1. Slenderiiz™ Day Drops

White Kidney Bean Extract

White kidney bean extract (WKBE) is a bioactive compound derived from white kidney beans. It may aid in weight loss by reducing carbohydrate absorption in the body.

Animal studies published in the Nutrients journal have demonstrated significant reductions in body weight or reduced weight gain following WKBE administration. 

In the study, mice subjected to a high-fat diet were divided into two groups, some were supplemented with WKBE while others received the control. The WKBE group gained significantly less weight compared to the control group.

We approve of this ingredient.

Cacao Bean Extract

Cacao bean extract is claimed to have the potential to increase feelings of fullness, reduce cravings, and boost metabolism.

A study in the Nutrients journal reported that consumption of cocoa bean extract powder containing 80 mg of flavonoids for 4 weeks by obese subjects showed a reduction in body weight, waist circumference, glycemia, and triglyceride. 

Slenderiiz contains 85.2 mg of cacao bean extract which is more than the required daily dosage to promote weight loss and thus may work.

We approve of this ingredient.

According to Dr. Olivia Harris, Clinical Nutritionist and Weight Loss Specialist "White kidney bean extract has demonstrated its potential to support weight loss by inhibiting carbohydrate absorption, while cacao bean extract may help control hunger and boost metabolism, making it a powerful addition to any weight management strategy."

Biotin

Biotin is vitamin B7 and works to improve the working of enzymes in various body functions and maintains the proper working of cells. Biotin sources include; avocados, beef liver, eggs, nuts, seeds, and sweet potatoes. 

While studies in the Journal of Medicinal Food agree that biotin supplementation can be helpful in the treatment of dyslipidemia, there is no clear evidence to prove that biotin can cause weight loss.

We disapprove of this ingredient.

L-Theanine

L-theanine found in tea is a non-protein amino acid that can aid weight loss by increasing metabolism and energy expenditure.

According to a 2021 study published in the Diabetes Journal, L-theanine was found to enhance adaptive thermogenesis and induce the browning of white adipose tissue which could help combat diet-induced obesity.

The required amount of L-theanine that can promote significant weight loss is 200-400 mg daily. Slenderiiz night drops only contain 100mg.

We disapprove of this ingredient.

L-Glutamine

Like L-theanine, L-glutamine is an amino acid with the potential to promote short-term weight loss. It’s claimed to reduce inflammation, alter gut microbiome, improve insulin sensitivity, and support weight management. 

A randomized controlled trial published in the European Journal of Clinical Nutrition subjected obese and overweight female patients to glutamine supplementation. Body weight and waist circumference significantly declined.

L-glutamine dosage of around 30 grams per day may boost weight loss. These drops contain only 25 mg of L-glutamine thus may not promote significant weight loss.

We disapprove of this ingredient.

Acerola Fruit Extract

Acerola fruit extract can aid weight loss as it contains polyphenolic compounds and fiber that may regulate blood sugar and reduce inflammation. It is also a rich source of vitamin C.

The Dias study published in the International Journal of Molecular Sciences showed that consumption of acerola juice in obese mice can prevent further weight gain and dyslipidemia when the test animals were fed a hypercaloric diet (to increase body fat in a short period of time). 

Consumption of acerola juice has been confirmed to lower triglyceride levels and inflammation in adipose tissues. While there are no scientific studies that have determined the specific dosage of acerola fruit to promote weight loss, the general guidelines are to consume about 500 to 1000 mg per day similar to the recommended daily intake of vitamin C.

Slenderiiz Night Drops contains only 5 mg of acerola fruit extract which may not be as effective for weight loss.

We disapprove of this ingredient.

Concerns Over Clinical Evidence

Although the manufacturer Ariix makes strong claims about Slenderiiz’s effectiveness, there is a lack of independent, scientifically validated evidence to support these assertions. The company disclosed that consumer trials were funded by a third party, with results described as “insane.” However, when asked about the credibility of this company-sponsored research, responses shifted toward anecdotal testimonials and business success rather than unbiased scientific data. This raises doubts about the reliability and validity of their claims.

Slenderiiz drops reviews and complaints about the product’s ingredients reveal that the quantities used are often far below those shown to be effective in clinical studies, and some ingredients lack any credible evidence for weight loss at all. This discrepancy between ingredient dosages and the amounts required for proven effectiveness casts further doubt on the supplement's ability to deliver the promised results.

We Tried Slenderiiz

To get a firsthand perspective of how this supplement works, I tried Slenderiiz Day & Night Drops myself. The daily recommended dose is to take 0.7 ml (15 day drops) before breakfast, lunch, and dinner. 

As for the night drops, I was only required to take it once which was 2 hours before bedtime. 2 ml or 45 drops is the required dosage. 

I would not recommend this product based on the following factors:

• Mixability – unfortunately, this product is not taken with food or drink. The drops should be placed under the tongue and allowed to dissolve before swallowing. 
• Taste – while the taste is not that unpleasant, you have to bear with it for 10 minutes before taking any drink to cleanse your palette. So if you don’t like the taste, there’s no other way around as you have to wait until it dissolves.  
• Effectiveness – going by the ingredients, we can agree that this product may not be as effective for weight loss since most of the ingredients are below the required dosage.
• Convenience – while Slenderiiz is easy to use, it may not be convenient if you are on a busy schedule, especially with the day drops which I was required to take three times during the day.

Consider exploring the Golo Release review as well. This product also claims to boost metabolism and promote weight loss, but does it truly live up to its promises?

Overall, this product is pretty decent, but there are best weight-loss supplements that have more effective ingredients at the right dosage.

For that reason, I’d rate Slenderiiz 5/10.

Side Effects & Safety

Although Slenderiiz drops are all-natural, they can still cause mild side effects. Ingredients such as green coffee bean extract and green tea leaf extract have caffeine content that could cause side effects in people with caffeine sensitivity. In these individuals, symptoms like headaches, anxiety, and jitters may be experienced.

Additionally, users may experience side effects such as nausea, stomach discomfort, and diarrhea because of ingredients like cordyceps and guarana seed extract. While these symptoms may disappear after getting used to the supplement, it could force one to quit before experiencing its full benefits.  

Other than that, L-theanine may cause:  

• Headaches
• Dizziness
• Irritability

While L-glutamine may cause:

• Headaches
• Back pain
• Constipation

As for users with existing medical conditions, before taking Slenderiiz, they should consult their healthcare provider to ensure this supplement is safe for them. Pregnant and breastfeeding women should also consult with their doctors to ensure this product does not have medical implications for them.

The U.S. Food and Drug Administration (FDA) has issued warnings about weight loss products, including those marketed as dietary supplements, due to the potential presence of hidden ingredients that can pose serious health risks. It’s important to approach such products with caution and consult healthcare professionals before use.

Real Customer Reviews

Ariix sells its products mainly on its official website making it difficult to get customer reviews from other platforms. Luckily we found some customer reviews on eBay where the product garnered a 5-star rating based on 15 reviews. Some of the reviews here are:

Love this product! After trying so many ways to drop weight at 70 years old, these drops have finally done their part as they are homeopathic. I’m very satisfied with my results. I’ve been taking this product for 6 months now.

However, when looking at Amazon, the slenderiiz reviews show that the product has a low rating of 2.6 out of 5 stars with some people complaining about undesirable taste and adverse effects. A few users also reported side effects such as nausea and an intense alcohol taste. One user stated, “It made me really sick and tasted like pure alcohol.” These bad reviews indicate some of the challenges encountered by the customers about the product more so about its taste and potential for causing discomfort.

On Trustpilot however, things are different. While the customers have not faulted the products, they are not impressed by the company’s business ethics. One example is Leslie who rated the company 2/5 and says,

Poor customer service! Been a customer for 2 years and products are OK but expensive. I have had a major problem with their auto delivery system. Website is poor and does not function properly. Almost impossible to make contact with their customer service. No response to 3 emails I have sent and I am now out of pocket by over £100 and have products I did not want or order. In summary, poor website and appalling customer service.

Looking at these reviews, we can say while the product may be decent and worth a try for those who are interested in homeopathic weight loss solutions, the hustle with customer care is not worth it. Some customers even claimed that Ariix is a pyramid scheme that’s out there to scam unknowing users out of their hard-earned money.

The amounts of active components in the drops are several times less than those that were proven effective in clinical studies. Weight loss success can be attributed to calorie restriction and increased activity and not the drops. Some users complained that they did not get any appetite-suppressing effects nor did they lose weight, particularly if they did not adhere to the strict regime of the low-calorie diet.

Weight loss in the Slenderiiz drops users is nearly always associated with a severe low-energy diet (typically 1,250 kcal/day). Experts believe that this kind of calorie-reduced diet alone can result in dramatic weight loss, independent of the presence of supplements. Any reduction in weight is therefore probably a result of the diet rather than the drops.

Whether this is true we cannot ascertain, but what we do know is that there are superior weight loss supplements on the market that offer better results. That too, from brands with professional business ethics.

Where to Find the Best Value

The best place to buy Slenderiiz is the official website. While you can purchase from third-party retailers such as eBay, buying directly from the Ariix official website ensures you get the authentic product.

On the official website, Slenderiiz Day & Night Drops go for a whopping $157.99 which is quite pricey for a weight loss supplement. For comparison, a product like KetoFuse, often considered one of the best supplements for weight loss, costs only $54.00, nearly a third of the price of Slenderiiz.

If you consider purchasing the whole package in the Slenderiiz weight loss program the price will be even higher. For instance, the Clinical Trial Weight Loss Program costs $465.99. 

Slenderiiz vs. KetoFuse

If we compare the ingredients of Slenderiiz and KetoFuse, KetoFuse takes the lead with its superior formula. KetoFuse contains superior weight-loss-boosting ingredients such as raspberry ketones, African mango, grape seed extract, and green tea extract.—all in effective, research-based levels. For example, KetoFuse contains 300 mg of African mango, an established dose for supporting weight loss, while Slenderiiz ingredient levels fall short of these maximum levels.

Beyond ingredient purity, KetoFuse offers clearer disclosure of individual dosages, as contrasted with Slenderiiz that resorts to vague "proprietary blends." Although Slenderiiz itself markets with such credentials as "clinically tested" and "all-natural" ingredients that may suppress hunger and boost metabolism, solid scientific substantiation is limited mostly to anecdotal accounts and promotional literature.

The second significant discrepancy is in terms of pricing: Slenderiiz is nearly three times more expensive than KetoFuse. With KetoFuse offering a superior-balanced formula at one-third the cost, it is better value and effectiveness for customers seeking a quality weight-loss supplement.
