The Best Greens Supplements For Nutrient Gaps, Reviewed By A Dietitian
To help you find the best options, I took a close look at the ingredients to ensure nutritional variety. I also considered who each formula might be best for—whether you’re always on the go, don’t love messing with powders, or are sticking to a tight budget. But before you spend your green on greens, it’s important to weigh the ingredients, format, dosage, and whether the product is third-party tested.
What To Consider Ingredients
Just like checking the label on your favorite snack, look closely at the ingredient list on your greens supplement to make sure it aligns with your dietary needs and preferences, even beyond the veggies. Some greens may contain extras, such as probiotics and adaptogenic mushrooms, which may not appeal to all. If you’re unsure about which ingredients best suit you, talk with a doctor, registered dietitian, or another healthcare professional.
Form
Greens supplements come in all shapes and sizes—powders, capsules, tablets, even gummies. Powders are the most versatile since you can stir them into water, juice, or smoothies. Capsules and gummies are super convenient, but may require more servings to match the nutrient punch of one scoop of powder. Think of it as choosing how you like your veggies and going with a form you’ll enjoy the most.
Dose
More isn’t always better. If you’re already taking a multivitamin or other supplements, be mindful of overlap, especially with nutrients like iron or fat-soluble vitamins (A, D, E, and K), which can build up over time. On the other hand, if you’re targeting a specific nutrient boost, choose a product that clearly lists its micronutrient content. Not all do, so it’s worth checking.
Third-Party Testing
Look for third-party certifications from trusted names like NSF or Informed Choice. These stamps of approval mean the product has been independently tested for quality, accuracy, and safety, giving you peace of mind that what’s on the label is actually in the bottle. While not every product is third-party tested, it can be especially important for competitive athletes or anyone wanting extra reassurance.
How We Chose
I’m a St. Louis-based dietitian with nearly a decade of experience in nutrition writing and editing. I also have an M.S. in Nutrition and Dietetics from Saint Louis University. After carefully researching and evaluating dozens of green supplements for a month, I came across these top six. I focused on ingredients, form, dose, and third-party testing when making my decisions. WH fitness commerce editor Nicolette Accardi also personally tested some of these supplements and provided informative notes and first-hand input.

Best Overall Green Supplement
AG1 Next Gen Pouch
Pros
Comprehensive, all-in-one formula to support immune, brain, gut, and overall health- NSF Certified for Sport, a reputable certification for quality, purity, and safety
- Convenient travel packs for easy, on-the-go nutrition
Cons
Uses proprietary blends, so exact ingredient amounts aren’t disclosed- Higher price point than many other green products
- The pouch—not the travel packs—needs refrigeration after opening, which may not be convenient for some
AG1 has been a frontrunner in the greens powder world for good reason. With a science-backed formula designed to fill nutritional gaps and enhance whole-body health, it earns its title as our best overall pick. And now with the release of AG1 Next Gen, the brand’s most significant upgrade yet, it’s clear the brand is not slowing down anytime soon.
The updated formula includes 83 ingredients (up from 75), with smart additions like choline for nervous system health, cocoa powder for antioxidant support, and boron, which helps your body use calcium and magnesium better. You’ll also find an improved probiotic blend aimed at digestive and immune health, along with more bioavailable forms of key nutrients like B vitamins and magnesium malate.
Even with these upgrades, the daily routine remains simple: Mix one scoop with eight to 12 ounces of water, sip, and nourish. And if you’re often on the move, the single-serve travel packs make it easy to stay consistent.
As for taste, Men’s Health fitness and commerce editor Charles Thorp, NASM says it’s a slight improvement in the flavor and texture. “The AG1 Next Gen is somewhat similar to the previous iteration, taste-wise, except it offers more of a pineapple flavor that provides a mild sweetness. This makes it pretty easy to just mix with water and not have to blend it into a smoothie (though you still can obviously). It’s certainly a lot more palatable than other green powders on the market.”
One of its biggest strengths is its NSF Certified for Sport status, which offers extra peace of mind, especially for athletes or anyone focused on quality assurance. Just keep in mind that while the brand is transparent about overall nutrient content, the proprietary blends mean you won’t see the exact amount of each ingredient.
AG1 does come with a premium price tag—around $3.30 per serving—though you can save if you opt into its subscription. If your budget allows, AG1 is a comprehensive, third-party tested green powder that continues to raise the bar.

Best Gummy Greens Supplement
Grüns Superfoods Greens Gummies 
Greens powders aren’t always the easiest sell—think earthy flavors and gritty textures. That’s exactly where Grüns Superfood Greens Gummies come in to resemble fruit snacks while still delivering all the benefits of a greens supplement that’s easy to take on the go—no water, no mixing, no mess.
Each plant-based pack of gummies is loaded with a blend of 60 ingredients, including organic alfalfa, kale, lemon, apple, and strawberry. You’ll get 100 percent of your daily value of key vitamins like A, C, D3, E, and K2, plus about 25 percent of your daily needs for minerals such as zinc, iron, copper, and chromium. They also pack in an impressive six grams of fiber, prebiotics, adaptogens, and functional mushrooms to support digestion, immune health, cognitive function, and overall wellness.
I’ll be honest that I was a little skeptical about the taste, but it surprised me in the best way. The flavor is like a balanced berry medley without that overpowering green taste you might expect. While it has a slight oily finish that caught me off guard, the texture is soft and chewy. WH fitness commerce editor Nicolette Accardi loves them instead of forcing herself to ingest bitter powder. “It doesn’t feel like a chore when taking these—I actually look forward to it,” she says. “It’s also a sweet treat I can feel good about taking.”
A few things to know: The low-sugar version still contains eight grams of added sugar, which could be a concern if you watch your intake. The sugar-free option uses allulose and stevia, and although not a dealbreaker, it could impact the flavor. Cost also varies between them, with the sugar-free costing about $3.15 per pack and the low-sugar about $2.85. That said, I appreciate the quality, and it may justify the higher cost to some.
Grüns are made in NSF-, GMP-, and FDA-certified United States facilities and tested for heavy metals and contaminants. I would love to see more transparency around who’s conducting those tests and sharing the results, but the commitment to quality is clear.

Best Tablet Greens Supplement
Ancient Nutrition Organic SuperGreens
Rather not risk the taste of greens with a sippable powder or chewable gummy? Ancient Nutrition Organic Super Greens is a solid tablet-based alternative to get a dose of nutrient-dense superfoods—no blender, shaker bottle, or cleanup required.
The formula includes two blends: the Organic Superfood Blend and the Organic Fermented Regenerative Superfood Blend. The first delivers well-known greens like kale, spinach, and broccoli, paired with antioxidant-rich fruits like wild blueberries, pomegranate, and elderberries. The second blend adds fermented ingredients such as turmeric, ginger, and avocado, which may help support digestion and boost nutrient absorption. Plus, you’ll get Bacillus coagulans, a probiotic known to support gut and immune health.
One downside is that the label doesn’t list specific amounts of individual vitamins or minerals, so you don’t know the exact nutrient content. Still, it’s free from added sugars, gluten, dairy, and soy, making it a clean, allergy-friendly choice for many. Each serving also requires three tablets, which might feel like a lot to some. But if you’re on the go or don’t love green powders, this format makes getting your greens way more convenient and simple. Plus, at about $1.50 per serving, they’re a more budget-friendly option to check out.
Best Gut Health Greens Supplement
Bloom Nutrition Super Greens Powder
Pros
- Helps support gut health with a blend of fiber, digestive enzymes, prebiotics, and probiotics
- Available in a variety of flavors, including Berry, Citrus, Coconut, Orange Passionfruit, and Pineapple
- Convenient single-serve travel packs fit easily into busy routines
Cons
- Uses proprietary blends, so exact ingredient amounts aren’t disclosed
- Lacks a full breakdown of vitamin and mineral content
- Claims third-party testing, but doesn’t specify which organization performs the testing
If gut health is your priority, Bloom Nutrition Greens & Superfoods is a solid addition to your routine. This green powder combines prebiotics, probiotics, digestive enzymes, and antioxidant-rich greens for supporting digestion, nutrient absorption, and overall wellness. Bonus: It’s available in convenient single-serve packets, making it a travel-friendly pick for beating bloat on the go.
Bloom’s formula includes seven proprietary blends, including its Prebiotic and Probiotic Blend to support a healthy gut microbiome, and Digestive Enzyme Blend for nutrient absorption and digestion. Two grams of dietary fiber is also in every scoop, from sources like chicory root and fructooligosaccharides to support regularity. Just keep in mind that it may cause gas or bloating if you have a sensitive digestive system.
But the perks go beyond gut support. The formula also includes blends designed to promote healthy aging and stress resilience, with adaptogens like licorice root extract and ashwagandha root. And, unlike most earthy-tasting greens powders, Bloom offers a range of naturally sweetened flavors like mango, berry, and strawberry kiwi, which Accardi says makes for a refreshing morning drink. Just know there is a slight stevia aftertaste, she says.
Some callouts worth noting: The use of proprietary blends means you won’t see the exact amount of each ingredient, and there’s no full breakdown of vitamin and mineral content beyond iron and sodium. Although Bloom states the product is tested for contaminants, it’s not third-party certified by groups like NSF or Informed Sport. That said, many consumers give it glowing reviews. Plus, it costs about $1.00 per serving, making it a more affordable greens supplement compared to other options in this guide.

Best Protein Powder Green Supplement
Garden of Life Raw Organic Plant Protein Greens
If there are two non-negotiables in a balanced, nutrient-rich diet, it’s getting enough protein and greens. And good news—you don’t have to live off chicken breast and broccoli to check both boxes. Enter: Garden of Life Protein & Greens Powder.
This blend combines plant-based protein and green superfoods in one easy scoop, making it a simple way to knock out two major nutrition goals at once. Each serving delivers 20 grams of complete plant protein—meaning all the essential amino acids your body needs—from organic peas, sprouted grains, legumes, and seeds.
And the greens? You’ll get a solid lineup of organic spinach, kale, broccoli, alfalfa grass, and more for a nutrient boost. While it’s not a top source of calcium, vitamin C, or potassium, it delivers up to 25 percent of the daily value of iron and zinc—two nutrients that can be a bit trickier to get enough of on a vegan diet since they’re more commonly found in animal-based foods.
Another perk: 1.5 billion CFU of probiotics plus digestive enzymes in every scoop. This is especially helpful if you’re new to plant-based protein and want to support digestion while your gut adjusts.
It’s also USDA Organic, NSF Certified Gluten Free, Certified Vegan, and Informed-Choice certified—meaning it’s been tested for banned substances and trusted by athletes and professionals who want to know exactly what they’re putting in their bodies.
Best For Stress Greens Supplement
Thorne Daily Greens Plus
If you’re looking for a greens powder that goes beyond the basics to help manage stress and support whole-body wellness, Thorne Daily Greens Plus is a standout choice. The formula features stress-supporting botanicals like ashwagandha, rhodiola, and eleuthero, along with a powerful lineup of adaptogenic mushrooms, including lion’s mane, chaga, reishi, and maitake help your body cope with stress and maintain balance. You’ll also get a gentle lift from 35 milligrams of caffeine sourced from matcha. It’s subtle enough to avoid the jitters, but worth noting if you’re watching your caffeine intake.
On top of that, Thorne includes antioxidants like glutathione, CoQ10, quercetin phytosome, and nicotinamide riboside. A study from the Journal of Pharmaceutical Analysis suggests these powerful ingredients can help reduce oxidative stress and inflammation, support brain health, and even protect against certain chronic diseases.
What I really appreciate about this green supplement is the full transparency. Unlike many blends that rely on proprietary formulas, Thorne lists every ingredient and its exact amount, so you know exactly what you’ll get in each scoop. That said, unlike other Thorne products, this one doesn’t appear to carry third-party testing or certifications, which would be a welcome addition for extra peace of mind.
At around $2.33 per serving, it’s a higher cost option. But if you’re seeking a greens powder that supports daily energy, mental clarity, and stress resilience, this one brings a thoughtfully curated blend of nutrients worth considering.

Can green supplements cause an upset stomach?
Green supplements can cause an upset stomach in some individuals, but it largely depends on the ingredients and a person’s unique health history. For example, if the greens supplement contains probiotics, users may experience temporary bloating or cramping as the gut microbiome adjusts. Those who aren’t used to higher fiber intake may also notice digestive discomfort. Additionally, individuals with sensitive stomachs or underlying digestive issues may be more prone to experiencing distress.
Who should avoid green supplements?
While generally safe, green supplements aren’t for everyone. Pregnant and breastfeeding women should proceed with caution, as some formulas may contain heavy metals and adaptogens that can be harmful. Those on blood thinners may also be at risk, as certain ingredients—especially those rich in vitamin K—can interfere with these medications. If you’re already meeting your nutrient needs through diet and other supplements, adding a greens powder could lead to excessive intake. As always, talk to your doctor before starting any supplement, especially if you’re pregnant, breastfeeding, managing a health condition, or taking medications.

Can green supplements replace produce intake?
While supplements can make reaching your goals easier, they should never replace a balanced diet based on whole foods. These are designed to fill nutritional gaps and are not meant as replacements for eating veggies and fruit.
