Chugging a glass of neon green vegetable powder isn’t always pleasant, but it may be one of the most effective ways to enhance your vitamin and nutrient intake. Before you trade in your multivitamin for greens powders, however, you should ask yourself a couple of questions. Namely, are greens powders worth the money? And if they are, then which greens powder is the best for me?

After testing dozens of the best-selling greens powder brands (as well as the underdogs that maybe don’t sell as well as they should), we’ve figured out which of them are worth your money and which are about as effective as drinking soil. In addition to a list of best greens powders, we explain their benefits and how they might affect your daily nutrition.

Best Greens Powder Overall

To pick the best greens powder overall, we considered several factors: micronutrients, phytonutrients, adaptogens, and ingredients for digestive health. 

Athletic Greens Ultimate Daily

Athletic Greens is an absolute nutrient powerhouse. One serving provides 700 percent of your daily Vitamin C, and 100 percent or more of most B vitamins (including B12), K2, and zinc. It also has the antioxidants of twelve servings of vegetables, 7.2 billion probiotic bacteria, digestive enzymes, adaptogens, and even ingredients linked to mental health, like Rhodiola Rosea and ashwagandha. The downside, though, is that a lot of those ingredients are wrapped up in blends, so you don’t really know what you’re getting.

Extraordinarily nutritious greens powder with many potential health benefits. Also one of the best-tasting greens powders on the market. 

Who Should Buy Athletic Greens Ultimate Daily

  • People who like greens powders for the digestive benefits: the probiotic bacteria and digestive enzymes here have some interesting links.
  • Those who take greens for their antioxidant content. There’s a huge variety of ingredients known for their antioxidant content, such as spirulina, wheatgrass juice powder, and chlorella.
  • Customers in the market for adaptogens that might help with stress levels. The Rhodiola Rosea and ashwagandha, in particular, are often used for this.
  • Athletes. Athletic Greens is NSF Certified for Sport®, meaning it contains what it says it contains. 

Who Shouldn’t Buy Athletic Greens Ultimate Daily

  • Those who prioritize transparency: many of the ingredients are in proprietary blends, making it tough to know the exact amount of each component you’re consuming.
  • Those looking for inexpensive greens. This one is pretty pricy, though it’s worth noting the cost drops if you sign up for a monthly subscription.

We’ve tried dozens, and Athletic Greens ticks the most boxes, consisting of a huge variety of healthful ingredients that may affect the body in myriad beneficial ways. 

Best Greens Powder for Fiber

Fiber can help with digestion and help you feel full. This pick offers more fiber than what’s found in your standard greens powder. 

Transparent Labs Prebiotic Greens 

In addition to four grams of fiber, which is four times more than some other brands, Transparent Labs also contains three grams each of just spirulina, broken cell chlorella, acacia fiber, and green banana flour, plus a gram each of artichoke fiber and chicory root. These sea greens are extremely dense chlorophyll sources, which have links to managing appetite and reducing body weight. (1)(2)  The prebiotic fiber here also has links to weight management as it may improve your gut microbiome. What’s nice is this modest label is extremely transparent, and every ingredient is listed in full.

Who Should Buy Transparent Labs Prebiotic Greens

  • People who want a greens powder with more fiber.
  • Folks who want to buy a greens powder that lists each ingredient in the full dose, as opposed to a blend.
  • Buyers who want a supplement with ingredients linked to improved digestion and to support the gut biome.

Who Shouldn’t Buy Transparent Labs Prebiotic Greens

  • If you’re looking for many micronutrients and adaptogens with your greens, this isn’t the product. Prebiotic Greens has a short, simple ingredients list that focuses on antioxidants and chlorophyll.
  • Folks who don’t mind blends, and may be able to find a cheaper alternative as a result.

Transparent Labs offers up a short yet sweet ingredient list that is fully dosed and backed by lots of research (made available on their website). Also, it contains more fiber than most other brands.

Best Greens Powder for Vitamins/Minerals

It’s not uncommon to see a greens powder that’s strong in a particular area — probiotics, enzymes, adaptogens, antioxidants — but then lack in others. In that sense, this pick stands out from the rest. 

PlantRise SuperGreens72 

With seventy-two ingredients (hence the name), PlantRise’s SuperGreens72 has blends for digestion, antioxidants, probiotics, and “superfoods.” And while we don’t love that some of the inclusions are proprietary blends, the nutritional label discloses the vitamin and mineral content, which we’ve found lacking in some other brands. 

PlantRise SuperGreens72
PlantRise SuperGreens72
PlantRise SuperGreens72

A greens powder with a huge variety of ingredients. Also has a pleasant, creamy taste and gets high marks in vitamin content, which some competing products leave out.

Who Should Buy PlantRise SuperGreens72

  • Customers who want multiple types of ingredients for a broader range of reasons (digestive health, antioxidants, vitamin intake, and so on).
  • People who want a wide range of ingredients in a daily greens supplement. 

Who Shouldn’t Buy PlantRise SuperGreens72

  • People who shy away from ingredient listings containing proprietary blends.
  • Customers who want something with higher Calcium and Vitamin D

SuperGreens72 is pleasant as far as taste and pretty comprehensive as far as ingredients. We wish they had disclosed all of the amounts in their blends, but we like that this supplement covers such a broad range of potential health benefits.

Best Greens Powder for Transparent Labeling

A lot of greens powders — including quality picks on this list — use blends. Here’s one pick that lists out each ingredient, in full, on their label.

Kaged Muscle Outlive 100

There are 26 superfoods listed on Outlive 100’s label, and you’re able to identify each one by name and see exactly who much you’re ingesting. A lot of greens powders, including picks on this list, rely on blends. This isn’t a bad thing, but some folks like to know how much they’re taking in of specific ingredients — either just because or they’re already taking a certain supplement and want to avoid overlap. Kaged Muscle’s formula is also vegan and comes in two delicious flavors: Apple Cinnamon and Berry. 

Kaged Muscle Outlive 100

Kaged Muscle Outlive 100

Outlive 100 is packed with 26 superfoods, all fully dosed, and it comes in two great flavors — Apple Cinnamon and Berry. 

Who Should Buy Kaged Muscle Outlive 100

  • Anyone who values complete transparency on an ingredient label. 
  • Folks who don’t like the taste of greens powders and want a product that’s flavored. 
  • Anyone who needs to chill out. This contains 300 milligrams of ashwagandha, which can help manage stress levels. 

Who Shouldn’t Buy Kaged Muscle Outlive 100

  • Anyone with a black pepper allergy. This product contains 50 milligrams. 
  • Folks who don’t mind blends, and would prefer more overall ingredients. 

Kaged Muscle focuses on transparency with their greens powder, offering 26 ingredients and their full doses. It doesn’t hurt that they replace the grassy flavor with a more desirable tang.

Best Greens Powder for Adaptogens/Stress

Some greens manufacturers have begun to formulate their products with specific focus on adaptogens, which could help the body better handle stressful situations. Common ingredient focuses include rhodiola and ashwagandha.

Organifi Green Juice

Organifi has been on the market for a number of years, and they’ve undergone several formulation tweaks in that time frame. Their current iteration has a heavy emphasis on ashwagandha, a potentially potent adaptogen the manufacturer claims could lead to “lowered cortisol levels… improved mood and reduced symptoms of stress.” (It’s worth noting more research is needed to firm up the link between ashwagandha and stress response in humans.) The product also contains other common greens ingredients like spirulina and wheatgrass.

Organifi's Green Juice has a heavy emphasis on adaptogens, especially ashwagandha. The product also features popular greens inclusions like spirulina, turmeric, and beet root. Green Juice is certified organic and Non-GMO Project verified. Get 15% off site wide with code "BARBEND".

Who Should Buy Organifi Green Juice

  • Customers who want a refreshing and lightly-sweetened greens powder
  • The manufacturer states the product is certified organic and Non-GMO Project-verified. These may be selling points for some consumers
  • Buyers who are particularly interested in the stress-fighting potential of adaptogenic ingredients

Who Shouldn’t Buy Organifi Green Juice

  • Folks looking for a specific amount of vitamins and minerals. The nutritional label is somewhat lacking in this information
  • People who are purchasing greens for probiotics; there are none included with this product

Organifi has taken an interesting approach to the greens powder space by leaning heavily into the inclusion of ashwagandha to potentially fight stress, among other ingredients. We particularly enjoyed the taste and would consider that a strong point for this product.

Best Greens Powder for Digestion

There’s interesting evidence that combining probiotic bacteria with prebiotic fiber helps to maximize both of their benefits for improving digestive health. That’s why Outlive 100 is our top pick in this category. 

Kaged Muscle Outlive 100

Part of Kaged Muscle’s 26-superfoods formula is geared toward digestion. It contains organic fiber as well as Activloe®, which is a purified aloe vera extract that has been shown to play a prebiotic role in the gut. There are also 100 milligrams of Actazin®, a cold-pressed kiwi powder also aimed towards easing digestion, and apple cider vinegar to aid in metabolic health. 

Kaged Muscle Outlive 100

Outlive 100 contains specific ingredients to aid in digestive health. These include Actazin and Activaloe, derived from kiwi and aloe vera, respectively, and play a role in gut health. 

Who Should Buy Kaged Muscle Outlive 100

  • People who have digestive issues and want a formula that may ease tummy trouble. 
  • Anyone who wants a brand that lists all of the ingredients in their full doses.
  • Folks who want a flavored greens powder.

Who Shouldn’t Buy Kaged Muscle Outlive 100

  • People who don’t want carbs in their greens powder. This one contains 13 grams, which isn’t a lot, but also not nothing. 
  • Folks who want more overall ingredients.

With specific ingredients geared toward easing digestive issues, Kaged Muscle’s Outlive 100 may be your answer to a healthier and happier gut. 

Best Tasting Greens Powder

It’s no secret that many greens powders taste…earthy. And if you hate the taste, you’re never going to drink the stuff. 

Athletic Greens Ultimate Daily

We thought Athletic Greens tasted the best of all the powders we tried. It leans on stevia and added flavorings like pineapple, papaya, carrot, and cherry powder to produce an actually enjoyable drink. We found ourselves sipping and savoring it, which isn’t something we’ve been able to say about any of its competitors. 

Athletic Greens Ultimate Daily

Most greens drinks taste like grass. We like Athletic Greens because it uses natural flavors and stevia to deliver a delicious, chug-worthy blend.

Who Should Buy Athletic Greens Ultimate Daily

  • Anyone tired of opening up a greens powder to find a powder that tastes like dirt.
  • Those who want a well-rounded greens supplement. It doesn’t just taste great. Athletic Greens is full of vitamins, probiotics, and adaptogens. 

Who Shouldn’t Buy Athletic Greens Ultimate Daily

  • If you object to the natural sweetener stevia, you’ll want to pass.
  • Regardless of your adherence to flavor as a virtue, anyone wanting an inexpensive greens powder may be disappointed by the price.

With tropical notes that taste like a creamy fruit punch, don’t look past Athletic Greens if you want a tasty and effective green drink. 

Best Greens Powder for Antioxidants

If you’re looking for a greens powder blend that delivers antioxidants, you want a brand that measures antioxidant doses using the ORAC (oxygen radical absorption capacity) scale.

ORAC-Energy Greens 

ORAC-Energy Greens has a score of 40,000 ORAC per serving — about 10 times what you find in a hundred gams of blueberries. Plus, it contains 42 ingredients: wheatgrass, alfalfa grass, a blend of seaweeds, and various adaptogens. Two more bonuses: it has a very mild taste, and it just costs a dollar per serving.

ORAC-Energy Greens
ORAC-Energy Greens
ORAC-Energy Greens

One of the very few greens powders that actually measures its antioxidant content, this is a very transparent and effective greens drink.

Who Should Buy ORAC-Energy Greens

  • Those who prioritize antioxidants: ORAC-Energy Greens is one of the few greens powders actually to measure its antioxidant content, and it’s higher than you’ll get in several servings of blueberries.
  • People on a budget. At about a dollar a serving, this is a pretty inexpensive greens powder.
  • Those looking for some adaptogens with their antioxidants. This product includes eleuthero root, Rhodiola, holy basil, ashwagandha, and ginseng.

Who Shouldn’t Buy ORAC-Energy Greens

  • Customers who focus on digestive health: ORAC-Energy Greens isn’t especially high in probiotic bacteria.
  • For people who want minerals out of their supplements. There’s not much information on the nutrition label about their content.

Many greens powders contain ingredients high in antioxidants, but they don’t actually measure their potency in this regard. ORAC-Energy Greens is one of the few that use the Oxygen Radical Absorbance Capacity scale, and so it got our top spot in this category. 

Best Greens Powder for the Money

The cost of greens powders can add up — fast. If you want to prioritize this supplement, there are budget options available.

MacroLife Naturals Macro Greens Superfood

For being the cheapest powder on our list, MacroLife Naturals delivers a substantial 18 billion CFU of probiotics from five different strains, four kinds of digestive enzymes, 720 percent of your daily Vitamin C, 330 percent of your Vitamin E, 50 percent of your B12, and eight percent of your iron. Though it has an antioxidant blend, it’s not quantified. 

MacroLife Naturals Macro Greens Superfood

One of the tastiest and most nutritious greens powders on the market, this also delivers more probiotics than almost any of its competitors — and it's very inexpensive.

Who Should Buy MacroLife Naturals Macro Greens Superfood

  • If you want to save cash while reaping all the benefits of greens powders.
  • Focusing on digestive health? This has 18 billion CFU probiotic bacteria and four kinds of digestive enzymes.
  • MacroLife provides them in the form of astragalus, echinacea, and ginger root powder if you’re looking for adaptogens.  

Who Shouldn’t Buy MacroLife Naturals Macro Greens Superfood

  • If your focus is antioxidants, little information is provided about the antioxidant content or the B-vitamins.

Many cheap greens powders give you wheatgrass and a nutrition label with nothing on it, but MacroLife pulled through with a huge range of ingredients and a surprisingly tasty berry flavor.

What Are the Benefits of Greens Powders?

When greens supplements burst onto the scene in the mid-2000s, they were marketed as the evolution of multivitamins. They’re not just sources of vitamins and minerals, however. Greens powders often contain antioxidants, probiotic bacteria, digestive enzymes, and naturally-derived compounds that are linked to everything from better-functioning livers to improved mental clarity.

But the biggest selling point is that those benefits come from naturally occurring foods. Usually, there are no isolated vitamins injected into the supplement — the nutrition comes entirely from whole foods taken straight from the ground, sea, or trees. 

“I love whole food sources as a means to get our nutrition and vitamins and minerals, so I like that a lot of the greens powders are derived from whole foods and plants,” says Gianna Masi, RDN, CISSN, CPT. “I really encourage everyone to pick one meal a day that’s a non-negotiable to get vegetables in. That’s a great place to start consuming more. Then, to add more antioxidants and polyphenols you could have a greens powder. It’s so important to remember that while powders can be great insurance, it shouldn’t take the place of trying to increase your veggie consumption.”

As Masi implies, the base of greens powders is made from a combination of grasses (like wheatgrass and barley grass) and algae (like spirulina and chlorella). The rest of the ingredients could be vegetables, fruits, mushrooms, roots, herbs, leaves, stems, fiber, probiotic bacteria, digestive enzymes, and royal jelly. Compared to multivitamins, greens powders aim to harvest the benefits of whole food ingredients that can sometimes be excluded from a daily multi. 

Plants don’t just contain the isolated vitamins and minerals you might get in other supplements. They’re also a source of fiber, chlorophyll, and phytonutrients like indole-3-carbinol (which may help with estrogen balance), isothiocyanates (which may decrease inflammation), and glucosinolates (which may lower the risk of heart disease). 

However, one potential issue with greens powders is that they’re relatively new. There aren’t many studies that have been performed on their potential benefits. That said, a couple of small studies published in the Journal of Chiropractic Medicine found that green superfood products caused study participants to experience a significant reduction in hypertensive symptoms, like better blood pressure. (3)(4)

These ingredients sometimes result in a tremendous amount of nutrition that vastly exceeds what’s offered in a multivitamin. Some greens powders can substitute for antioxidant supplements, digestive health supplements, adaptogen supplements, and natural herb supplements like Rhodiola Rosea or milk thistle. When it comes to gut health, Masi suggests using a greens powder or a stand-alone probiotic. Otherwise, you risk digestive trouble. She also adds that greens powders or probiotics shouldn’t be considered a fix for gastrointestinal disturbances, and to always seek out a doctor if you have intense GI issues. 

How We Decided the Best Greens Powders

To measure the different greens powders’ effectiveness on this list, we paid attention to the four areas below.

Micronutrients in Greens Powders

We know that many feel the point of greens powders is that they offer more than a multivitamin.  And many greens powders make claims such as “equal to four servings of vegetables” and “a great source of vitamins and minerals.” We feel that it’s important to gauge a product’s vitamins and minerals contents. It’s a surprisingly difficult task, as many of these products state that they’re full of everything the body needs while leaving most vitamins and minerals off of the nutrition label.

Even if a label claims a certain number of servings worth of vegetables, Masi says to not accept that as your daily veggie consumption. “I’m still going to encourage real food sources due to their bioavailability (how much of them are absorbed) and fiber content,” she says.

Antioxidant Content in Greens Powders

Perhaps the most common claim made about green superfood powders is how jam-packed they are with antioxidants. There’s no line for ‘antioxidant strength’ on a nutrition label. However, some methods of measuring a product’s antioxidants, like the ORAC score, let you measure the antioxidant content against, say, a cup of blueberries. Very few products do this, so we don’t mark them down too heavily if they don’t include their score, but it’s a big bonus when they do.

Adaptogens and Herbs in Greens Powders

A lot of the most exciting research in nutrition is on adaptogens, which are compounds that may alter the way the body responds to stress. One adaptogen that is often seen in greens powders is Rhodiola Rosea, which may improve focus and exercise performance. Reishi mushrooms, which have been linked to everything from subjective well-being to better immunity, is another. (5)(6)

Probiotics and Enzymes in Greens Powders

Maintaining a healthy population of gut bacteria — the trillions of little critters that live in your digestive tract and help you break down food — may tamp down inflammation, boost immunity, and positively impact your mood. Digestive enzymes and prebiotic fiber are also tied to a healthier gut and often find their way into greens powders as well. We look for these ingredients in our selects.

Greens Powders Vs. Multivitamins

As is mentioned above, greens powders are supposed to be more complete and nutritious compared to a general multivitamin. Here’s the rub though: Greens powders are also A), considerably more expensive, and B) they may not be absorbed as effectively. 

An article published by the Cambridge University Press asserts that plant-based diets can result in micronutrient deficiencies, but not just because a plant-based diet is naturally low in nutrients found in animal products (such as iron and magnesium). According to the article, plant-based diets are also associated with “poor micronutrient bioavailability,” meaning they’re not absorbed as efficiently. (8) While Johns Hopkins found multivitamins to not be an effective solution against heart disease, cancer, or mental decline, it also didn’t say anything against its absorption rate. 

While prices do vary based on brand, multivitamins are generally cheaper than greens powders. So, if you’re looking to simply take in extra vitamins and minerals, then a multivitamin may be both more cost-effective and better absorbed. That said, a greens powder contains more antioxidants and nutrients, as well as adaptogens and other possibly holistic herbs — so there’s that. Ultimately, the decision will come down to your preference and priorities. If you already eat a solid diet but want more extras, then the greens powder could be for you. 

Here’s the thing, though: articles and studies on both multivitamins and greens powders say that nothing can replace a balanced diet that consists of raw (or cooked) greens and healthy whole foods. A plate of fresh broccoli is better for you (not to mention more filling) than a glass of dehydrated, ground-up greens. 

Here’s a summary since we threw a lot at you:

  • Talk to your doctor about what minerals and/or vitamins you need, because you may be better off taking a multivitamin over a greens powder.
  • Greens powders contain more antioxidants, nutrients, and herbs compared to a multivitamin. (Though, one article says that plants aren’t as bioavailable.) 
  • The best way to get more vitamins, minerals, and nutrients, according to research, is a diet abundant with whole foods such as vegetables and fruits. 

What to Know Before Buying a Greens Powder

Before you click “order” on your new greens powder, consider these three points.

mad drinking green shake

These Don’t Replace Vegetables

There are way too many green superfood drinks that advertise themselves as the equivalent of a serving of fruits and vegetables (or three). That’s not how it works. Fresh fruits and veggies contain far more ingredients and phytonutrients than you’ll find in an average scoop of greens, in addition to fiber and water. Eat your fruits and veggies!

Know Why You’re Buying

As you can see, greens powders can have many different focuses: antioxidants, digestive health, and adaptogens, to name a few. Do some research and know the strengths and weaknesses of your product before you commit.

Consult With Your Doctor

Always speak with your physician before undertaking a new supplement regimen.

Different Ways to Take Greens Powders

Don’t think you have to just mix greens powders into a glass of water and slam it (though you can). Here are a handful of creative ways to get in your greens (powder).

  • Mix them into your shake: If you’re the type of person who prefers a more elaborate protein shake, then you may want to consider tossing a greens powder into the mix. Assuming you add protein, some milk, and various fruits, you may not even taste the greens powder. Of course, you may be thinking, “What if I already add veggies to my shake.” Well, that’s great, but a greens powder may contain a more broad and varied ingredient profile than what you’re getting from just a handful of kale. You can cut the serving in half and add the powder if you’re concerned about veggie overload. 
  • Bake a frittata: A frittata — a dish that consists of eggs (and/or egg white), veggies, proteins, and cheese that’s baked in the oven  — is a convenient grab-and-go meal, packed with protein. With all of those flavors intermingling, chances are you won’t notice two scoops of your greens powder throw in for a nutrient boost. That said, it’s possible that baking the powder may kill off some of the nutrients (though, this isn’t confirmed). 
  • Make a pesto: The same logic applies to the above two suggestions. The next time you whip-up a pesto, a sauce that’s already green and earthy, try adding a scoop of greens powder to give it an even more earthy flavor and color. Then, go ahead and slather that onto chicken or beef, a hearty flatbread, or a salad.
  • Bake brownies: Ok, this isn’t the healthiest suggestion, but brownies present a strong chocolate flavor that can mask the greens. Also, you can try making protein brownies, which has you add whey protein powder to a brownie recipe for more protein. 

Frequently Asked Questions

What is a greens superfood powder?

A green superfood powder, also just called a greens powder, usually refers to a supplement that contains a base of antioxidant-rich algae or grasses, typically wheatgrass, barley grass, spirulina, and/or chlorella.

Usually a greens powder will also contain ingredients for digestive health (like probiotic bacteria), adaptogens (plants that can help improve stress levels), and/or added vitamins and minerals.

What are the benefits of greens superfood powders?

Greens powders typically contain ingredients high in antioxidants, which may slow certain aspects of aging. They may also improve nutrient absorption (especially when they contain probiotic bacteria, prebiotic fiber, and/or digestive enzymes), and help the body respond to stress (when they contain adaptogenic herbs or mushrooms).

Note that greens powders don’t usually contain a lot of vitamins and minerals, but there are plenty of exceptions — check the nutrition label for more.

Do greens powders detoxify my body?

No. The liver is what removes toxins from your body, and neither cleanses nor juices nor eating extra vegetables will detoxify your body.

However, some greens powders contain ingredients that support the body’s natural detoxification processes. The most notable and common example is milk thistle, a flowering herb that has been linked to liver health. (7) (It’s sometimes used to help treat hepatitis and cirrhosis of the liver.) Most greens powders contain milk thistle to support using the word “detox” on their label.

Can a greens supplement boost my immunity?

Many greens powders do contain ingredients that are linked to a healthier immune system. In particular, most are a source of antioxidants, which protect the body’s cells from free radicals, harmful molecules that may contribute to the risk of cancer. Therefore, it can be argued that antioxidants may reduce your risk of disease.

The same can be said of many nutrients that are often found in greens powders, like Vitamins A, C, E, B-6, zinc, selenium, iron, and copper. Any supplement that contains any amounts of any of these micronutrients could be said to potentially improve immunity.

Final Word

Of all of the health and wellness supplements on the market, green superfood powders are among the newest — and they’re also among the toughest to scrutinize. We get it: many of them make outlandish claims and barely try to support them with information on their nutrition label. But while you can’t “out supplement” a poor diet, many of the best greens powders may well confer benefits to some areas of your health. After digging through a lot of muck, we’ve uncovered some truly excellent supplements. We think you’ll be as impressed with them as we were.
