In a world saturated with weight loss promises, few programs are as aggressively marketed—and as critically flawed—as Slenderiiz. Developed by ARIIX, now part of the Partner.Co conglomerate, Slenderiiz is sold as a “natural” and “scientifically backed” weight management system. It includes two main products, Slenderiix and Xceler8, both homeopathic drops marketed to boost metabolism, suppress appetite, and burn fat. Together, they’re called ‘Slenderiiz Skinny Drops’…because ‘skinny’ sells, I guess.
This Slenderiiz Skinny Drops review will take a look at the products and the promises that are the Slenderiiz program.
If this sounds too good to be true—it probably is. The effectiveness of these products is questionable at best, the claims behind them are unsubstantiated, and the way they’re sold through a multi-level marketing (MLM) model raises serious red flags.
Let’s break down what Slenderiiz is, what it claims to do, what it actually contains, and why the MLM structure it’s built on poses ethical and financial concerns.
What Is Slenderiiz?
Slenderiiz is a branded weight loss system sold through a network of independent distributors. At its core are two liquid supplements:
Slenderiix: A homeopathic formula marketed to “flush fat and toxins,” “curb appetite,” and “signal your hypothalamus to mobilize fat.”
Xceler8: A companion drop designed to “boost metabolism,” “increase nutrient absorption,” and “enhance the effects of Slenderiix.”
These are often sold in bundles alongside a 1,250-calorie meal plan and suggested exercises.
The marketing claims sound impressive—some even say Slenderiiz is the “only healthy and natural weight management system of its kind.”
But the evidence tells a very different story.
Slenderix Ingredient Breakdown: The Homeopathic Illusion
Slenderiix contains a variety of highly diluted homeopathic ingredients, including:
Ammonium Bromatum (12X) – Traditionally used in homeopathy for respiratory issues.
Avena Sativa (6X) – From oats; thought to support the nervous system.
Calcarea Carbonica (6X) – Derived from oyster shells; often claimed to suppress appetite.
Fucus Vesiculosus (6X) – A seaweed rich in iodine, used for thyroid function.
Nux Vomica, Ignatia Amara, Graphites, and others.
All of these ingredients are diluted to the point where there may be no measurable amount of the original substance left—a hallmark of homeopathy.
This is important: homeopathy is not supported by modern science. I usually call it ‘the air guitar of medicine,’ because the ‘treatments’ are basically water. Systematic reviews, including from the UK’s National Health Service and Australia’s National Health and Medical Research Council, have concluded that homeopathy is no more effective than a placebo. In other words, Slenderiix relies on ingredients that are unlikely to do anything physiologically meaningful.
The primary ingredient Xceler8 is vitamin B12, which is readily available in food. There is also a ‘proprietary blend’ of different adaptogens and other plant ingredients, none of which have any evidence it terms of aiding weight loss. Proprietary blends are a way for companies to hide the amounts of ingredients in products, and honestly, I think they should be illegal. They’re not only shady, they’re also potentially dangerous. You need to know how much of exactly what is in something you put into your body.
Xceler8 is described as a blend that “enhances energy, supports digestion, and improves sleep”—yet again, without clear evidence or transparency.
What Does the Science Say about Slenderiiz?
Nothing. The science says nothing. Do you know why? Because Slenderiiz has no scientific evidence to support its claims. This isn’t shocking; I see it all the time.
I went looking for Slenderiiz research, and all I found was a PDF review of one horribly done study using Slenderiiz products. No control group. Not peer reviewed or published in a reputable journal. So many confounders. The layperson may look at this and think it means something. I can tell you right now, it doesn’t.
The NIH has this at the top of its description of Slenderiiz:
Disclaimer: This homeopathic product has not been evaluated by the Food and Drug Administration for safety or efficacy. FDA is not aware of scientific evidence to support homeopathy as effective.
The UK’s Advertising Standards Authority (ASA) investigated Slenderiiz in 2014. The company provided a self-funded study that claimed participants lost weight using the program, but the ASA ruled the claims misleading. The primary issue? The weight loss could easily be attributed to the restrictive 1,250-calorie diet—not the products themselves. This is a common marketing ploy that I’ve seen a lot with weight loss supplements. There’s something so disgusting and off-putting about a company whose site is called ‘Slender and Skinny.’ Is this what we’re aiming for now?
The ASA concluded the evidence was “not sufficiently robust to support the claims” and banned the company from making such claims in UK advertising.
The U.S. Food and Drug Administration (FDA) has also taken action against similar homeopathic and weight-loss supplements for unproven claims. While Slenderiiz itself hasn’t been specifically cited, it’s in a category that the FDA scrutinizes closely—especially when bold claims are made without clinical backing.
The Red Flags of MLMs
Slenderiiz isn’t just a product—it’s a ‘business opportunity.’ ARIIX (and now Partner.Co) uses a multi-level marketing structure. That means individual “brand partners” sell products to earn commissions, but more importantly, they recruit others to do the same—building downlines and earning overrides from their team’s sales.
This structure is eerily similar to pyramid schemes in practice, if not always in legal definition.
Some issues with MLMs include:
Exaggerated Income Claims: Distributors are often sold the dream of financial freedom. In reality, less than 1% make significant money. Many lose money after buying inventory, attending conferences, and paying for training.
Recruitment Pressure: The system rewards building a team more than selling the product. This leads to aggressive, sometimes exploitative recruiting—especially among friends, family, and online communities.
Health Misinformation: Reps with no scientific or medical training promote health products and make bold claims not approved by regulatory bodies.
Emotional Manipulation: Testimonials are used to inspire trust, even when those outcomes are rare, unverified, or driven by placebo and calorie restriction.
The FTC and other agencies have warned the public about MLMs in the wellness space, specifically calling out the risk of deceptive health claims and financial loss.
I wrote more about MLMs, their tactics, and their salespeople here.
Here’s a social media post from ‘Doctor’ Kristal Vance, a chiropractor who sells Slenderiiz:
Slenderiiz marketing is especially rampant on platforms like Instagram, TikTok, and Facebook. Distributors often post personal “before and after” photos, list benefits like “increased energy,” “better sleep,” or “fat melting,” and use hashtags like #skinnydrops or #naturalweightloss.
Here are a few real examples of marketing claims seen on social media or company blogs:
“Slenderiiz flushes toxins and stubborn belly fat from your system—naturally!”
“The Slenderiiz skinny drops suppress your appetite and help you burn more calories, even at rest.”
“I lost 15 pounds in 30 days thanks to Slenderiiz and clean eating.”
None of these statements are supported by independent research. Worse, they may target vulnerable people—those struggling with self-image, disordered eating, or medical conditions—offering false hope.
Homeopathy and Health Buzzwords: A Dangerous Combination
The Slenderiiz brand, like many wellness MLMs, leans heavily on buzzwords that sound scientific but are often meaningless:
“Detox”: Your body already detoxifies itself using your liver and kidneys. No homeopathic drop can “flush toxins.”
“Boost metabolism”: A vague term often misused. No evidence shows Slenderiiz can elevate resting metabolic rate.
“Natural”: Arsenic is natural too. “Natural” doesn’t mean safe or effective.
“Clinically tested”: A favorite phrase, often used even when the studies are unpublished, self-funded, or poorly designed.
These words prey on consumers’ desire for safe, effective solutions—without delivering the results promised.
Slenderiiz features a doctor in its marketing. In my opinion, a trustworthy MD would not be selling homeopathic weight loss drugs.
Regulatory Oversight: Are Agencies Doing Enough?
While the ASA in the UK has taken action against Slenderiiz claims, similar products often slip through regulatory cracks elsewhere.
The FDA does not approve dietary supplements before they go to market. Companies are responsible for ensuring safety and labeling.
The FTC does act against fraudulent or misleading marketing—but only when there’s overwhelming evidence or high levels of consumer harm.
NSF and other certifications touted by ARIIX apply to product quality and safety, not effectiveness.
Consumers are left navigating a market full of lofty promises, minimal oversight, and inconsistent accountability.
Final Thoughts: Slenderiiz Review
Slenderiiz markets itself as a cutting-edge, all-natural weight management system. But beneath the shiny branding and influencer testimonials is a system built on homeopathy, misleading health claims, and an MLM structure that benefits the few at the expense of the many.
Here are some red flags to watch for:
Over-the-top weight loss promises
Lack of published, peer-reviewed evidence
Distributors using emotional language and unregulated testimonials
Heavy focus on recruiting others rather than the product itself
If you’re trying to lose weight or improve your health, consider talking to a registered dietitian, a licensed healthcare provider, or a certified fitness professional. Focus on sustainable nutrition, physical activity, sleep, and stress management—not ‘miracle drops.’
