Quince supplements review: Your favorite clothing company is dipping its toes into the wellness space

The Quince Tencel Jersey Fit & Flare Dress is one of my go-to pieces, and don’t even get me started on the brand’s five-star hotel-worthy bamboo sheets. Its sleek luggage? It looks like it costs double the price. Clearly, I’m a fan. So when I, a dietitian who spends hours each day reviewing supplements, heard that Quince was expanding into wellness, I was immediately interested. Agreeing to test the brand’s new supplement line and writing a review was an easy decision to make.

For those unfamiliar, Quince has built its reputation on offering high-quality, sustainably sourced essentials — clothing, jewelry, luggage and home goods — at prices that are more accessible for the everyday consumer. Loyal fans (myself included) love that the brand’s products consistently look and feel like they cost far more than they do. Now Quince is bringing those same standards into the health and wellness space. Its debut supplement collection includes everything from electrolyte and protein powders to adaptogens and magnesium, all produced in FDA-registered U.S. facilities and third-party tested for purity. I tried (almost) the full lineup to see if these new offerings deserve a place in your wellness routine. Before we dive in, it’s worth noting that while I received the products for free, all opinions and reviews are my own and have not been reviewed or endorsed by Quince.

How we tested

With the exception of Quince’s Daily Super Greens — which was tested by Yahoo contributor and fellow RD Rachael Ajmera — I personally tried every supplement over the course of one month. I followed the directions on each label and aimed to use the products as intended. For example, I took the Magnesium Glycinate powder nightly before bed for three weeks, and I used the Lion’s Mane and Stress Relief capsules daily for two weeks each. The electrolyte powders fueled my hikes, but I also reached for the Everyday Electrolytes on sunny weekends with my kids — even when I wasn’t doing a full-on workout.

Here are the key factors I evaluated during testing:

• Delivery and packaging: The products arrived on their expected delivery day, and everything was in tip-top shape — no torn bags or broken capsules.

• Ease of use: All of the supplements had clear, easy-to-follow instructions. The powders came with scoops and were all relatively easy to measure out. The capsules, while a bit large, were easy to swallow, even two at a time.

• Taste: I’ll dive into specifics below, but as a whole, I was impressed by the taste of the supplements I tried. The only supplement where taste was a deal breaker was the Daily Superfoods Greens.

• Side effects: With the exception of one product, I tolerated the supplements well. The Recovery Electrolytes made me a bit nauseous, though I suspect this was due to its sodium content being much higher than what I actually needed for my activity that day.

• Noticeable benefits: I was surprised that even with a relatively short testing window, I experienced some noticeable benefits, especially after using the Lion’s Mane and Magnesium Glycinate Plus.

• Formulation: I evaluated each product’s formulation, noting bioavailability of nutrients and evidence-backed doses. Overall, the products feature easy-to-absorb nutrient forms and doses supported by research. That said, some ingredients have weaker evidence to support their use (especially when it comes to adaptogens).

• Added ingredients: Quince’s supplement lineup stands out for its minimal ingredient lists and zero artificial additives. Products are also free of common allergens, and many are vegan-friendly.

• Quality measures: As noted above, Quince products are manufactured in FDA-compliant facilities and are third-party tested for purity. However, with the exception of two products that are made in NSF-compliant facilities, I didn’t see any mention of potency testing (in other words, testing to determine whether products contain the types and amounts of ingredients listed on the label).

The product lineup — and what we thought

Kelli McGrane, MS, RD

better sleep. While more research is needed specifically on magnesium glycinate, this form is often used for its potential calming properties, which may make it easier to drift off at night. Quince’s Magnesium Glycinate Plus combines 325 mg of magnesium glycinate with 112 mg of L-theanine, an amino acid also associated with relaxation and stress relief. 

It’s worth noting that many human studies use 200 mg or more of L-theanine, though early animal research suggests that combining L-theanine with magnesium may create a synergistic effect — enhancing their impact compared with using either ingredient alone. And because Quince’s blend contains 0 grams of added sugar, you don’t have to worry about it spiking your energy before bed or taking a toll on your teeth.

The packaging is thoughtful too: The compact lilac bag is attractive enough to leave on your nightstand or bathroom counter, and the long-handled scoop makes measuring easy without creating a mess. The powder dissolved quickly in water and gave off a pleasant berry aroma. However, I didn’t love the taste. Despite being free of artificial flavors, it tasted slightly medicinal and reminded me of something artificially sweetened. That said, it mixes into as little as 4 ounces of water, so you don’t have to sip a full glass if you don’t enjoy the taste. Most important, it worked — I felt noticeably calmer and found it easier to fall asleep faster. Thanks to my 2-year-old’s middle-of-the-night wakings, I can’t speak to whether it helps you stay asleep, but it worked well as a wind-down aid.

Psst: See more of our favorite magnesium supplements here. 

Pros

• Ingredients linked with benefits for stress and relaxation
• Easy to scoop and mix
• Helped me fall asleep faster

Cons

• Artificial-like taste
• L-theanine dose is slightly lower than what’s used in many studies

protein powders — including plenty of vegan-friendly ones — and Quince’s Certified Organic Plant Protein ranks among the best in terms of ingredient quality. Made from a blend of organic peas, brown rice, chia seeds and pumpkin seeds, it provides all nine essential amino acids. Each serving also includes 1 billion CFU of dairy-free probiotics and 30 mg of digestive enzymes designed to support gut health.

While the probiotic strains included have research to support their use for general gut health, digestive enzyme supplements haven’t shown much benefit in people without certain conditions, like pancreatitis and cystic fibrosis. Plus, some digestive enzymes can interact with blood-thinning medications. 

Each scoop provides 21 grams of plant-based protein, 120 calories and 0 grams of added sugar. It’s also an excellent source of iron and phosphorus, with a good amount of calcium as well. My favorite feature? It skips stevia, which can leave an overpowering taste and aftertaste, and instead uses monk fruit for natural sweetness. I honestly couldn’t detect it. Instead, it had a rich, chocolaty flavor that worked especially well in a post-workout shake. 

As for texture, it blended beautifully into smoothies, giving them a creamy consistency. But when mixed in just a shaker bottle, I found it a bit too gritty for my liking. One more small note: Like many protein powders packaged in bags rather than tubs, scooping can get a little messy. Still, I’d consider these minor issues for an otherwise solid formula.

Pros

• Manufactured in an NSF-compliant facility
• Third-party tested and certified organic
• Vegan-friendly and free of major allergens
• Suitable for keto diets
• Zero added sugar, stevia, sugar alcohols or artificial flavors
• Complete amino acid profile
• Includes probiotics for gut health
• Rich and creamy when added to smoothies and shakes

Cons

• Limited research to support the benefits of digestive enzyme supplementation
• Probiotics may not be necessary for or wanted by everyone
• Gritty when mixed with just water or milk
• Only available in chocolate and vanilla

collagen supplements. Collagen is the main structural component of hair, skin, nails, bones, tendons, muscles and other tissues. While it isn’t a magical time machine, a 2023 review in Nutrients suggests collagen supplements may help with skin aging by improving hydration and elasticity, though more robust studies are needed to confirm. The supplement also includes vitamin C — important for collagen production — and hyaluronic acid, which early evidence suggests may help improve skin hydration, tone and thickness. 

Quince’s Collagen Peptides Plus features collagen sourced from grass-fed cows and is free from added sugar, stevia and artificial additives. The powder was quite fine, but easy to scoop and dissolved quickly in my coffee. However, when mixed into a glass of cold water, it needed frequent stirring as it kept separating. Flavorwise, it had a milky, powdery taste that wasn’t my favorite either. However, the taste worked well when added to coffee.

From a price perspective, this powder is actually a great deal, as many popular options on the market cost closer to $40 per bag. As with Quince’s other supplements, it’s third-party tested for contaminants but not for potency. 

Pros

• Contains other ingredients that may support skin health
• Zero added sugar, stevia or artificial flavors
• Good value
• Mixes easily into hot beverages
• Easy to scoop
• Third-party tested for purity

Cons

• 110 mg of sodium per serving
• Isn’t third-party tested for potency
• Isn’t suitable for vegans
• Separates in cold beverages

Quince Daily Superfood Greens reads like a multivitamin. In fact, each scoop provides 23 essential vitamins and minerals, many in amounts higher than 100% of the daily value (DV). Also included is a raw superfood complex, with ingredients like wheat grass, inulin, spirulina, spinach, carrot, kelp and more. What’s more, there’s an herb and antioxidant blend, a digestive enzyme and adaptogenic mushroom blend and a dairy-free probiotic blend. As with many greens powders, these blends are proprietary, meaning the amounts of each ingredient listed aren’t disclosed, making it hard to know whether ingredients are present in research-backed doses. 

Ajmera tried this blend, along with 12 other greens supplements. She gave it kudos for its competitive price and all-in-one formulation, which may be particularly appealing if you take multiple supplements and are looking to consolidate your routine. However, this powder wasn’t her favorite, noting that it had a “very strong sweet and fruity flavor and aftertaste that was difficult to drink.” She also found it to be one of the hardest to mix: “[I] had to stir it again before almost every sip because it separated very quickly. After finishing the drink, there was a good amount of residue at the bottom. I think this greens powder needs to be used with a shaker bottle or blended instead of mixed using just a spoon.” 

Ultimately, while she said the flavor might be improved when combined with other ingredients, “based on the taste, texture and usability, I think there are better choices available at a similar price point.”

Pros

• Third-party tested in an NSF-compliant facility
• Vegan-friendly
• No added sugar or artificial additives
• Potential to replace multiple supplements
• Relatively affordable

Cons

• Many ingredients may not be necessary or appropriate for everyone
• Hard to mix and had a strong, unpleasant taste
• Contains proprietary blends

electrolyte powder can help replace key minerals like sodium and potassium. The tricky part is that many powders on the market contain more sodium and sugar than most people need. 

Quince’s Everyday Electrolytes strikes a nice middle ground with 300 mg sodium per serving to help support hydration along with 250 mg potassium and 100 mg magnesium. I tested the sweetened version, which contains 5 grams of added sugar per serving, though Quince also makes an unsweetened option. 

I first tried the mix on a light summer hike, and the travel-friendly packaging was a win — easy to stash in my bag and pour straight into a water bottle on the trail. The powder dissolved quickly with a few shakes, and the flavor was truly enjoyable: Not too sweet or salty. The raspberry taste was refreshing and unlike many other electrolyte powders, it didn’t have an artificial or chemical aftertaste.

Pros

• Sweetened and unsweetened options
• Pleasant taste with no lingering aftertaste
• Travel-friendly packaging
• Mixes easily and quickly
• Provides three key electrolytes
• Only 5 g of added sugar in the sweetened variety
• Third-party tested for purity
• Vegan-friendly

Cons

• Only two flavor options
• Sodium content may be too high for some
• Isn’t third-party tested for potency

Recovery Electrolytes are essentially a souped-up version of the brand’s zero-sugar Everyday Electrolytes. In fact, the only difference (other than a tiny bit more calcium) is the sodium content, which is bumped up to 1,000 mg to support more substantial sodium losses after exercise or during illness. For this reason, I wouldn’t recommend it for everyday hydration or for a more moderate workout session. 

Also, keep in mind that this mix is carb-free, which may be a downside depending on your needs. Carbs, including sugar, are key for replenishing glycogen stores during intense workouts, so this may be a deal breaker for some athletes if they don’t have an alternative source of glucose, like an energy gel.

During testing, this powder was easy and convenient to add to a water bottle on a hike. However, the high sodium content didn’t sit well with me. While it’s impossible to know for certain, I suspect that my body simply didn’t need the higher sodium content. That aside, the taste was pleasant, though definitely salty, with no artificial or chemical aftertaste. 

Pros

• Third-party tested for purity
• Vegan-friendly
• Free from stevia, sugar alcohols and artificial additives
• Contains three key electrolytes
• Convenient travel-friendly packaging
• Good taste, though definitely salty

Cons

• Doesn’t contain carbs, which are important for recovery
• High sodium content isn’t necessary for everyone
• Isn’t third-party tested for potency

lifelong mushroom-hater, I was hesitant to try Quince’s Organic Mushroom Coffee. While it still isn’t the product for me (we’ll circle back to that in a moment), I’m happy to reassure you that there’s zero mushroom or earthy taste. Instead, it was reminiscent of a light black tea, like Darjeeling, with strong cinnamon notes. However, fellow super-tasters beware: When combined with water, this mix is quite bitter. Adding milk helps a bit, but it still wasn’t my cup of tea … er, coffee. 

Texture-wise, the powder dissolved quickly into a hot mug of water with zero grittiness and very little sediment at the bottom. Thanks to the use of adaptogenic mushrooms and L-theanine, mushroom coffee is supposed to offer a gentle boost of energy without the jitters of a regular cup of Joe. While I certainly didn’t feel jittery, I didn’t notice any differences in energy, focus or anxiety either. And research seems to support this. While some research suggests adaptogens may have benefits for focus, energy levels and stress, the overall evidence is limited and inconclusive. 

All of that to say, if you’re interested in trying mushroom coffee, this could be a good place to start. Not only is the price competitive — many mushroom coffees cost around $40 per bag — but all of the ingredients and amounts are listed. This means you can actually see whether the types and doses of adaptogens listed line up with those used in research. 

Pros

• Competitive price
• No detectable mushroom or earthy flavor
• Strong cinnamon taste
• Third-party tested for purity
• USDA organic
• Vegan- and keto-friendly
• No added sugar or artificial additives
• No proprietary blends — all ingredients and amounts are listed

Cons

• Bitter
• Isn’t third-party tested for potency
• Limited research to support the benefits of mushroom coffee

Certified Organic Lion’s Mane. Each two-capsule serving provides 1,000 mg of lion’s mane extract — an adaptogenic mushroom often marketed for reducing brain fog, improving memory and supporting long-term brain health. Most of the existing research, however, has been conducted in test tubes or on animals, so it’s still unclear how well these findings translate to humans.

That said, the few small human studies that exist are promising. For example, a 2020 study in older adults with mild Alzheimer’s disease found that taking 1,050 mg of lion’s mane daily for 49 weeks significantly improved cognitive function. In addition, two small studies in younger, healthy adults found that daily doses of 1,800 and 3,000 mg of lion’s mane significantly improved cognitive performance. The dosage in Quince’s supplement is consistent (though on the low end) with what’s been used in early human research — though much more evidence is needed before we can make firm recommendations.

As for the product itself, the capsules are on the larger side but were still easy to swallow, even two at once. They had a faint earthy smell but no noticeable taste or aftertaste. After taking them daily for two weeks, I didn’t notice any changes in memory, energy or focus. What I did experience, though, was a slight reduction in brain fog and a calmer mindset in the mornings — which, as any parent wrangling two kids solo before day care knows, is no small feat.

Pros

• Third-party tested for purity
• Certified organic
• No artificial additives
• Easy to swallow
• No taste or aftertaste
• Vegan-friendly

Cons

• Limited research on the effectiveness of lion’s mane
• Isn’t third-party tested for potency
• Large capsule size

Daily Stress Support contains four adaptogens intended to help the body better adapt to stress. According to a 2023 review in the Journal of Functional Foods, adaptogens affect the hypothalamic-pituitary-adrenal (HPA) axis, which in turn could help keep cortisol levels steadier throughout the day. The review also notes that ashwagandha (which is included in this blend) currently has the most research supporting its benefits for stress. Still, it’s worth repeating that, overall, research on the benefits of adaptogens in humans is limited. 

After taking Quince’s lion’s mane supplement for two weeks, I stopped and switched to this one. I was surprised that, unlike the lion’s mane capsules, I didn’t notice any changes in brain fog, stress or anxiety. The good news, though, is I didn’t experience any negative side effects, either, and found these equally easy to swallow. 

Pros

• Relatively affordable, compared to other adaptogen supplements
• Third-party tested for purity
• Contains ashwagandha, which has some evidence to support its potential stress-relieving effects
• Easy to swallow
• Certified organic
• No artificial additives
• Vegan-friendly

Cons

• Limited research overall on adaptogens for stress
• Isn’t third-party tested for potency
• Large capsule size

How Quince’s supplements compare

There’s no shortage of vitamin supplement brands. When thinking of who best to compare Quince to, mindbodygreen immediately came to mind. Both brands are relative newcomers in the supplement industry, offer similar types of wellness products and feature short ingredient lists free from artificial additives — their packaging is also equally visually appealing. That said, the brands have some key differences. Most notably, mindbodygreen’s supplements are third-party tested for both purity and potency, but tend to be more expensive than Quince’s.

Here’s a quick look at how the brands compare:
