SkinnyFit Greens Review (2024): Get the Skinny on This Probably-Overpromising Powder

SkinnyFit Skinny Greens is a popular greens powder supplement containing a superfood blend, adaptogen blend, gut health blend, and weight loss blend, each consisting of various fruit and vegetable powders, fibers, extracts, and more. 

The brand makes a lot of promises regarding this supplement (and its other products), so we decided to test it for ourselves and find out if any of the claims are true. We fact-checked the entire supplement facts label for our SkinnyFit Greens review—let’s find out if it can actually help you lose weight, boost your mood, or increase your energy.

Product Reviews Written by Subject Matter Experts

Greens powders claim to do a lot of things, like help you manage your weight or even blood sugar or cholesterol. The problem is, such claims are almost always unsubstantiated and impossible to corroborate without clinical research. What’s a shopper to do? Read GGR’s expert-written, in-depth product reviews, of course! Our reviews, like this SkinnyFit Greens review, are informed by hands-on product testing (and tasting), hours of reading scientific literature, and collaboration with registered dietitians and Ph.D.-level nutrition experts.

A Quick Look at SkinnyFit Greens Powder

Skinny Greens is a “green juice superfood powder” from SkinnyFit, a maker of various dietary supplements. Other popular items from the brand include SkinnyFit Super Youth Collagen Peptides and “Skinny Gummies.”

SkinnyFit claims that Skinny Greens delivers a potent dose of antioxidants, supports immune system health, promotes improved gut health, and increases energy levels.

Before You Buy

• This product—like a lot of greens powders—is marketed with a lot of unsubstantiated claims. There is no proof that greens powders can induce weight loss, and there’s little evidence to support their efficacy in general. When shopping for greens powders, take these claims with a grain of salt (and know that losing weight requires a controlled caloric deficit achieved through exercise and a nutritious diet).  

• There is no information on the label of this product regarding micronutrient content. Because there is no way to tell how much vitamin A, B, C, D, E, or K (not to mention minerals) is included, it’s imperative to check the labels on your other supplements, such as a multivitamin, to make sure you’re not already reaching the defined tolerable upper limits¹.

Is SkinnyFit Daily Greens Powder Worth It?

Skinny Greens powder could be a good option for some people. Here’s a look at who might be a good match for this supplement.

Experience Using SkinnyFit Greens

GGR staff writer and product tester Lauren Strong tried SkinnyFit Skinny Greens, testing it out in both a shaker bottle and in a glass stirred with a spoon. Overall, she thought it was OK in terms of taste and texture, and that it’s nice to see a greens supplement with not just greens, but also adaptogens and ingredients for gut health.

Price Per Serving

Skinny Greens costs about $3 per serving for a one-time purchase made on the SkinnyFit website. That’s on the high end, up there with Athletic Greens and Supergreen Tonik. Many of our top picks for greens powders cost less than $2 per serving.

Formulation

SkinnyFit Skinny Greens has a formula made up of four parts. 

• The Wholesome Superfood Blend consists of a variety of whole-food-sourced powders from green leafy vegetables, cruciferous veggies, and grasses.   
• The Healthy Gut Probiotic Blend contains fiber from inulin powder; bromelain, a protein-digesting enzyme found in pineapples; a digestive enzyme blend of amylase, lactose, cellulase, protease, and lipase; and a probiotic blend of 10 bacterial strains totaling 500 million CFUs.  
• There’s a Mood-Boosting Adaptogen Blend containing coconut water powder, turmeric root extract, ashwagandha root powder, American ginseng root extract, and rhodiola root powder.  
• Finally, the Slimming Greens Blend contains glucomannan root, green tea leaf extract, and apple cider vinegar.

This all looks benign enough on the surface, but let’s take a closer look at some of the blends and ingredients. 

Firstly, all of these ingredients are present as proprietary blends, which means it’s impossible for anyone to know how much of each ingredient is present in the powder. So while the superfood blend, for instance, boasts a list of healthy veggies that’s nine items long, we have no idea how much wheat grass powder is in the blend compared to how much spinach powder. 

We only know that the blend itself totals 3.405 grams, which, truth be told, is unlikely to be an impactful amount. It’s tough to say, because there aren’t yet any clinically recommended dosing guidelines for concentrated fruit and vegetable powders like there are for, say, creatine. While there’s minimal evidence supporting concentrated food powders for anti-inflammatory purposes² and reducing markers of disease³, research is lacking overall and convoluting the ingredients in a proprietary blend makes it even harder to judge the quality of such supplements. 

What we do have guidelines for is probiotic intake. In 2014, the International Scientific Association for Probiotics and Prebiotics⁴ published a position statement declaring that the minimum effective dose of probiotics—and the minimum for a product to even be called a probiotic supplement—is 1 billion CFUs (colony-forming units). Research shows⁵ that an effective dose of probiotics in healthy individuals ranges from 5 to 20 billion CFUs.

Some research even suggests that the most effective dose is 100 billion CFUs or more⁶. 

The effective dose depends heavily on the strain of probiotic and what, exactly, “effective” means—different strains confer different health benefits and efficacy is all relative to the condition or symptom at hand. Regardless, the CFU count in SkinnyFit Skinny Greens’ “gut-renewing probiotic blend” totals just 500 million CFUs, which is far below the minimum recommended dose.

OK, let’s move onto the adaptogen blend. There’s a growing body of evidence⁷ supporting adaptogens for stress relief, focus, cognitive function, and general health and wellness. Once again, though, the effects of adaptogens are dose-dependent, and SkinnyFit doesn’t provide any information on how much of each adaptogen is in the blend. We only know that the entire blend totals 670 milligrams. However, by looking at the suggested effective doses of individual adaptogens and comparing those amounts to the blend’s total, we can infer that there is unlikely to be an effective dose of any of them. 

Case in point: The effective dose of ashwagandha is between 240 to 600 milligrams⁸. The effective dose of ginseng root extract is thought to be 200 milligrams⁹. The effective dose of turmeric (not curcumin¹⁰, turmeric’s bioactive compound) supported by clinical studies is 100 to 1,500 milligrams per day¹¹, depending on the condition one is trying to treat. And the estimated effective dose of rhodiola root extract is 200 to 600 milligrams¹² per day. 

If you take the minimums for all four ingredients (240 + 200 + 100 + 200)—and we’re not even including the coconut water powder here—you have 740 milligrams, which is already more than the blend’s total amount of 670 milligrams. 

Although the formula seems severely underdosed, registered dietitian Bob Iafelice, Ph.D., says everything is not always as it seems with greens powders. 

“As part of a multifaceted green drink, [the dosages] may not be as important because you’re getting health benefits from such a wide range of plant phytochemicals,” Iafelice explains. For example, “some of the greens and/or adaptogens may help gut health,” making it so that “a few hundred million CFUs may suffice.”

RELATED: Best Ashwagandha Supplements

Finally, let’s talk about the “Slimming Greens Blend.” Right off the bat, I have to tell you that there is absolutely no evidence that greens powders support weight loss, and consumers should be wary of any powder or pill that promises such a thing. 

The blend includes glucomannan root, apple cider vinegar, and green tea leaf extract. The former is a water-soluble fiber that may have multiple health benefits, like all soluble fibers. 

Can it work as a weight loss supplement? Maybe—in a randomized controlled trial¹³, participants who supplemented with glucomannan lost more weight than other participants. It’s important to note that the participants were also on an energy-restricted diet putting them in a caloric deficit, which also contributes to weight loss.  

Additionally, the effective dose is considered 2 to 4 grams of glucomannan per day¹⁴, and SkinnyFit greens doesn’t even contain a full gram of the “slimming blend,” meaning there’s far less than a gram of glucomannan in this powder.

As for apple cider vinegar (ACV)¹⁵ and green tea leaf extract¹⁶, there’s limited evidence that either could help with weight loss in combination with a caloric deficit. I’m not one to make assumptions, but based on what we know about the other proprietary blends in SkinnyFit greens, it’s unlikely that there’s an effective dosage of either ingredient to confer benefits.  

Taste and Solubility 

On the upside, our product tester Lauren Strong says that SkinnyFit Skinny Greens powder has great solubility. “It mixes fine in a shaker bottle or in a glass with a spoon,” she says. 

As for taste, Lauren says, “Eh. It’s a greens powder! It’s not the worst, but the tartness of the green apple flavor makes this kind of a weird experience.” 

“I sort of puckered a little while testing the first time,” she continues. “I’ve since watered this mix down a bit more—14 ounces is the recommended amount of water but I put a splash more. To be fair, my first test was in an 8-ounce juice cup.”

Side Effects

Lauren herself didn’t experience any side effects after taking SkinnyFit Skinny Greens, but there are some unfavorable reviews on Amazon mentioning adverse effects. Stomach pain and various forms of gastrointestinal discomfort were noted. 

People who are taking blood thinners, particularly warfarin and drugs with the same mechanism of action, should check with their doctor before using SkinnyFit Greens or any greens powder. Concentrated vegetable supplements are typically high in vitamin K, and vitamin K interacts with warfarin. The label on this product doesn’t disclose the amount of vitamin K, so it’s imperative to talk with your healthcare provider before taking it.

Third-Party Testing 

Skinny Greens is not third-party tested by an independent laboratory. Third-party testing is important because it ensures that products are free from things like pathogens, allergens, heavy metals, and performance-enhancing drugs that can get athletes banned from competition. 

While we highly value third-party testing, we respect that such testing is very expensive to undergo and some companies, especially smaller ones, can’t afford it. However, when there is a lack of third-party testing, we look for transparency in other areas, such as not using proprietary blends and clearly stating the amounts of ingredients on the label. 

Skinny Greens does not have either form of transparency, which makes us hesitant to recommend it. 

SkinnyFit Greens vs Athletic Greens AG1

Athletic Greens AG1

Athletic Greens AG1

GGR Score: 4.25

Check Price

Product Highlights

• Contains 75 minerals and nutrients in one serving
• Available in travel pouches and bundle and save options
• Said to support gut health with prebiotics, probiotics, and naturally occuring enzymes
• Supports immunity with key ingredients like vitamin C and mushrooms
• Magnesium is added to boost energy
• May aid in recovery as it features superfood complex with adaptogens and antioxidants

Pros & Cons

Pros

• Backed by notable health experts
• Transparent and detailed ingredient list
• 75 vitamins and minerals

Cons

• Expensive
• Some reviewers dislike the taste

Bottom Line

If you’re looking for a greens powder with a unique blend of minerals, nutrients, power greens, enzymes, and probiotics and you're willing to spend some money, Athletic Greens may be a good choice for you.

Athletic Greens AG1 is considered the gold standard in greens powders. It undergoes third-party testing and discloses the micronutrient profile including the daily value percentage of vitamins and minerals. Unfortunately, even Athletic Greens uses proprietary blends (but calls them “complexes”) so we don’t know the milligram or gram amounts of each ingredient. 

The blends are present in much higher amounts, with the superfood blend totaling 7,388 milligrams compared to Skinny Green’s 3,405 milligrams and the probiotic count totaling 7.2 billion CFUs compared to Skinny Green’s 500 million CFUs.  

Both are expensive—Skinny Greens costs $3 per serving and AG1 costs $3.30 per serving—but based on the labels, you’re getting a lot more for your money with AG1. You can learn more about AG1 in our Athletic Greens Review.

Customer Experience 

One great thing about SkinnyFit is their customer-centric policies. For example, every purchase made on the SkinnyFit website is eligible for a 90-day money-back guarantee. So if you don’t like Skinny Greens for any reason, you can return it within that window. Keep in mind that this guarantee doesn’t apply to purchases made on other retailer sites, including Amazon. 

Ordering SkinnyFit Greens

The main places to buy Skinny Greens are the SkinnyFit website and Amazon. The ordering process is standard, but you can sign up for subscribe-and-save options on the SkinnyFit site to save 15%. At the time of writing, that option doesn’t seem to be available on Amazon. 

Customer Reviews

There are nearly 2,000 reviews on the SkinnyFit website, most of them very positive. On Amazon, the product has an average rating of 4.1 out of 5 stars based on more than 3,300 reviews. 

Most reviews praise the product for helping with energy, bloat, mood, or digestion. Some reviews claim that the powder has helped them lose weight, while others say they bought it for weight loss but haven’t noticed any changes. 

Lauren, our product tester, noted this, too. “While the reviews are overwhelmingly positive, one of the first 3-star reviews I read says ‘I still haven’t lost any weight which has been disappointing,’” Lauren says. “This makes me so sad and angry because this brand markets this as a weight loss cure,” which, as we’ve covered, it isn’t. 

Some negative reviews indicate problems with quality control and concerns that the container seems really empty upon arrival. Several buyers were surprised with how much product was (or wasn’t) in the tub. 

Final Verdict of Our SkinnyFit SKinny Greens Review

SkinnyFit Skinny Greens is a well-rounded greens powder with several ingredient categories we like to see in this type of supplement: whole food powders, fruit/veggie/root extracts, adaptogens, digestive enzymes, and probiotics. 

However, most of the ingredients seem to be underdosed, and we aren’t thrilled that SkinnyFit markets this as a surefire weight loss aid. Though it contains a few ingredients that might help with weight loss in conjunction with a healthy diet, they may not be present in helpful amounts.

Bowflex VeloCore Review: Innovative Leaning Bike 2024

by Caroline Lubinsky, CF-L1

About a month ago, I was watching TV and an advertisement for the new Bowflex VeloCore popped on screen. I was fascinated to see a bike trying to compete with Peloton but with an added layer of intrigue: it can lean while you’re riding. Right away, I knew I had to order it and try it out for all you fine folks in the Garage Gym Review community.I love the core engagement you get when using the lean mode on this bike. It’s such a unique and fun feature that separates the VeloCore from other exercise bikes for a home gym. In this Bowflex VeloCore review, you can expect to see my opinion on what really matters – durability, overall value, and the leaning feature. I put this bike through my standardized tests to help you decide if this is worth your money. Read more
