15 Best Greens Powders of 2024, According to a Registered Dietitian

Alright, alright—we know that Athletic Greens AG1 is expensive. In fact, at $3.30 per serving, it’s the most expensive on our list by far. (A one-time-purchase bag of 30 servings costs $99). But trust us, there’s a reason this greens powder is the clear winner in our book.

Bob Iafelice, a registered dietitian who recommends AG1 to his clients who prefer a one-stop shop for their nutrient needs, says this product has it all. Out of all the greens powders we tested, AG1 ranked the highest for its ingredient formulation with a perfect 5 out of 5.

“While the whole superfoods provide important plant compounds that are missing in some multivitamin formulas, specific amounts and forms of critical vitamins and minerals supported by research studies are also included,” he explains. “For example, AG1 contains vitamin K2, a type of vitamin K that’s predominantly found in animal foods (as well as fermented soybean). Vitamin K2 has been shown to play a vital role in promoting bone mineralization².”

AG1 was formulated with athletes in mind, and has an ingredient list that includes vitamins and minerals; a raw superfood complex made of wheatgrass and barley grass, plus others; an adaptogen blend of extracts, herbs, and antioxidants, including ashwagandha; an enzyme and mushroom complex; and probiotics. Because of the probiotics, the company recommends keeping your bag of AG1 in the refrigerator once it’s opened to preserve the “integrity and efficacy” of the ingredients—a downside if you’re on the go a lot, but not a dealbreaker.

Oh, and speaking of athletes the supplement has an NSF Certified for Sport mark so you know it’s been tested for potentially harmful materials and banned substances that might show up on a drug test.

This certified personal trainer and nutrition coach was excited to try this athlete-grade green superfood powder. It actually has a very pleasant taste if you ask me—mildly like pineapple and vanilla, but you still get the slightly earthy flavor that greens powder normally provides. I had no problem drinking this on its own. In fact, our team rated AG1 a 4.5 out of 5 for taste, which makes this one of the best-tasting greens we tried.

Another thing our testers noticed is that while the greens thoroughly mixes into the liquid, it tends to settle after a few minutes so you might have to re-shake if you don’t plan on downing this in one gulp. It’s still good enough for us to give it a 4 out of 5 on solubility.

Looking for something as good as AG1, but not quite as pricey? At around $2.00 per serving, Live It Up Super Greens is still on the more expensive side—though you can save nearly $20 if you put it on a subscription basis. However, this saves over a dollar per serving compared to AG1, and the greens powder is filled with tons of beneficial nutrients and ingredients.

Most greens powders are beneficial for gut health, since they’re packed with fiber-rich ingredients that can help with bloating. Live it Up takes it a step further by including probiotics and digestive enzymes linked to improved digestion and immune health.

Bifidobacterium bifidum—a probiotic found in Live it Up Super Greens—has been found to help protect the body against infections, alleviate chronic gut conditions such as Irritable Bowel Syndrome, and help regulate people’s immune system, according to a November 2019 review¹⁶.

“The bloating has been going away for me,” says expert product tester Lindsay Scheele, who’s used Live it Up for more than six months. “I miss this product whenever I’ve run out of it in the past.”

It’s available in two flavors: Original (mint) and Wild Berries. Lindsay tried the mint flavor, which she rated a 4 out of 5. “These greens have a really nice minty aftertaste that helps you feel as if you are not drinking a cup of grass,” she says in our Live It Up Super Greens review. She ranked the solubility the same score, saying it mixes pretty well though he’s found that he’s had to add more than the suggested amount of liquid to get it fully incorporated.

Prebiotics³ are non-digestible food substances (mostly carbohydrates) that play a vital role in overall health by feeding the gut microbiota, thus stimulating the growth of beneficial microorganisms, like probiotics. The gut microbiota ferments prebiotics, resulting in the production of short-chain fatty acids, such as butyrate, which can exert multiple health benefits for the body.

Transparent Labs Prebiotic Greens is available in Unflavored or Peach Mango, and at $1.33 per serving, it’s on the more affordable side for greens powders. (You can check out the latest Transparent Labs discount codes for more savings, too.)

This certified personal trainer tried Prebiotic Greens in Peach Mango, and it’s true—this is definitely top-ranking for taste in my opinion, earning a 4 out of 5 on our rating test. It is sweetened with stevia, which you can taste, but it’s not off-putting like in some products. It’s nice and sweet and it mixed up fine—not quite as nicely as some of the others on the list, but it didn’t detract from the drinking experience. 

Certified sports nutrition coach Amanda Capritto recommends mixing it with orange juice to take away some of the earthy taste.

“Transparent Labs Prebiotic Greens is rich in these health-enhancing prebiotics, including organic acacia fiber and organic green banana flour,” registered dietitian Bob Iafelice says in our Transparent Labs Prebiotic Greens review. “I’ve discovered that this unique blend of concentrated, naturally sweet prebiotic greens, together with Stevia, offers a highly nutritious greens drink with a great taste as well.”

True Nutrition’s Custom Daily Greens allows you to personalize your greens powder supplement as you want to, depending on your health needs and goals. You can select the type of greens base, add ingredients like turmeric to address inflammation or probiotics for improved digestion, select the exact flavor you want, and even add protein or fiber to your mix.

The exact type depends on what ingredients you use and how much is in your final mix, though we’ll note that each pound of powder only comes with 14 servings.

Registered dietitian Bob Iafelice called the product an “interesting concept.

“Creating your own customized greens drink can be fun and especially beneficial for people who have allergies/intolerances to certain greens/fruits,” he says. “This seems to be more of a fun niche product for the experienced supplement user, not for someone with little nutrition knowledge who just wants a good, proven greens drink.

As he notes, you are taking a chance at creating your own supplement and the final product might clash with your chosen flavor, depending on what type of ingredients you include. “You’re taking a chance on a finished product that you can’t sample first,” he says.

While we haven’t sampled the custom greens blend, our testers have sampled the unflavored version of True Nutrition’s Super Greens and we rated it a 3 out of 5. “Overall taste is somewhat bitter with an aftertaste,” says registered nurse Kathleen Penner, a former physique competitor. Similarly, the solubility scored low at a 2.5 out of 5.

“No matter how much I shaked, the bottle still had leftover green grit all over the sides of the bottle and a small amount in the bottom,” Kathleen says. “Mixed with a juice, somehow it dissolves more so give it a 3 with juice.”

While Legion Genesis Greens is tasty enough to take on its own, we think its Original or Acai Berry flavor would be a great addition to your morning protein smoothie. GGR Senior Director of Content and weightlifting coach Kate Meier rates the Acai Berry flavor a 4 out of 5.

“I was able to drink the entire serving without gagging,” she says, which wasn’t the case for many other greens powders she tried. “It was pretty enjoyable.” In terms of solubility, Kate rates it a 4.5 out of 5 because it requires a good bit of hand mixing, though she noted it dissolved easily in a blender.

Many of the top greens powders contain spirulina, which is a blue-green algae known for its health benefits. For example, it is a rich source of B vitamins. Also, according to research, just 3 grams of it can reduce mental and physical fatigue.⁷

You’ll find 5 grams of organic spirulina in Legion Genesis Greens, which has been tested to verify that what is on the label is actually what is in the greens powder.

That’s not the only reason our testers and dietitians rated Legion a 4 out of 5 for formulation; Genesis has a number of other research-backed ingredients in recommended (or higher) dosages:

• 3 g of Reishi mushroom fruit powder, said to improve brain and liver health
• 1.5 g of maca root extract, which can improve libido and sexual function
• 1.25 g of dong quai root, which supports immunity
• 3 g of astragalus membranaceus, which promotes heart health and supports immunity

While we love that Legion products are third-party tested, and that there are no proprietary blends here, it is disappointing that there is nothing on the label indicating the vitamin and mineral content. Also, this is one of the more expensive greens powders on our list at $2 a serving (though you can subscribe and save a little bit of money).

The term superfood simply refers to a food that has minimal calories and a large amount of vitamins, minerals, and fiber. Nested Naturals Super Green offers all that, and then some, starting with three sources of fiber: apple powder, rice bran soluble powder, and Jerusalem artichoke inulin powder.

RELATED: What Are Super Greens?

Under 10 percent of U.S. adults get enough fiber through their diet, according to the American Society for Nutrition. Fiber is connected to improved digestive health, immune health, blood sugar levels, and cardiovascular health. It should be noted that Nested Naturals doesn’t provide your entire day’s worth of fiber — men require 38 grams and women need 25 grams per day—but it’s a quick and easy way to fill some of the nutrient gap.

Frieda Johnson, longtime fitness writer and Garage Gym Reviews editor, scores the taste a three out of five in our Nested Super Greens review. “It tastes like what I imagine a cow thinks grass tastes like,” she says. It gets a 4 out of 5 for solubility, with Frieda saying she noticed no obvious clumps or unmixed powder in water or orange juice.

At around $0.99 to $1.06, depending on where you buy it from, it’s an affordable greens supplement that won’t break the bank, especially if you put it on a subscription basis.

You may be asking yourself, “How can a greens powder help me with weight management?” While it’s true Organifi Green Juice won’t magically make the pounds drop off your waistline, it contains an important ingredient that’s been linked to weight loss: Ashwagandha, which has been linked with decreased stress that could help you achieve a caloric deficit.

If you’ve suffered from stress, you know it can lead to disruptions to your sleep and appetite, but it can also lead to physiological changes that can make weight loss harder. While ashwagandha supplementation isn’t a magic bullet, there’s more than enough scientific evidence pointing to it as a stress reliever.

“Ashwagandha root extract reduces psychological and physiological markers of stress, improves mental well-being, and reduces serum cortisol level and food cravings and improves eating behaviors,” states one study⁴. “[It] can be useful for body-weight management in patients experiencing chronic stress.”

Organifi puts 600 milligrams of the nootropic in every serving, which is the same dose used by most researchers looking into the link between ashwagandha and weight loss.

So it’s good for you, but how does it taste? Well, according to certified personal trainer and sports nutrition coach Amanda Capritto, the Crisp Apple flavor is a 4.5 out of 5. “This is one of the better greens powders I’ve tried, taste-wise,” she says. “It kind of tastes like those bottled green juices you can pick up from Whole Foods or Sprouts. Very tangy and tart.”

Our one callout is the price—a 30-serving bag will run you around $70, coming out to $2.33 per serving. That’s a 1 out of 5 for value in our book, but the more than 6,700 5-star Amazon reviews have us thinking it may be worth it.

Ora Organic promises that it’s “easy being green” with their supplement, and our testing and research indicates that’s true because of the wide variety of greens used and it’s commitment to third-party testing their products for purity.

It’s also dairy- and gluten-free, so it’s easy on the gut, and bears the USDA-certified organic mark along with being a certified vegan product.

Certified nutrition coach and GGR performance editor Anthony O’Reilly says he experienced no bloating with this product, and that it had a less grassy taste than others he’s tried. Unfortunately, the orange flavor that replaced those “grassy notes” wasn’t his favorite. “They say they use natural flavors, but it did not taste natural to me,” he says, rating the overall taste a 3 out of 5.

Several customer reviewers felt similar about the taste, though some were fans after experimenting with different ratios of water to orange juice. The one thing they and Anthony have in common is they felt better after taking it.

Registered dietitian Bob Iafelice says one issue with this supplement is that it uses proprietary blends that hide the exact amount of certain ingredients, such as adaptogens ashwagandha. ” So you don’t really know what you are getting here,” he says. He also notes that there’s no fruits in this greens powder.

Regarding price, it costs around $1.20 per serving, which is enough for it to get a 3.5 out of 5 on price.

ProHealth’s Longevity Greens powder blends an impressive collection of greens together to create a vegan, allergen-free (with the exception of wheat), USDA organic formula that contains no artificial flavors and is packed full of high-quality ingredients. It also comes in a Apple Banana flavor and has no artificial sweeteners.

Multiple studies⁷ have shown that organic foods have lower levels of toxins, such as heavy metals, synthetic fertilizer, and pesticide residues, so ProHealth Longevity Greens could be a good choice. 

Registered dietitian Bob Iafelice, however, notes there are 3 grams of added sugar, which might not make it the best choice for diabetics. “It may unnecessarily raise blood glucose and insulin because there is no significant fat or protein to buffer the effects of the sugar on blood glucose/insulin levels,” he says. He also points out that there’s no plant-to-extract ratios provided for the ingredients, as there are on other greens powders, so we’re rating the formulation a 3 out of 5.

On the bright side, the company has all of its supplements tested by third-party labs and has certificates of analysis available. This is especially important for people who take regular drug tests or want to ensure their greens powders are free of potentially harmful substances, but since they don’t use a major organization, we’re rating the transparency a 3 out of 5.

Our testers rated the Apple Banana flavor a 4 out of 5, saying it had just the right amount of sweetness but the banana flavor was missing. “The apple is the strongest flavor—maybe slightly sour apple,” says one of our expert product testers.

They also rated the solubility a 4 out of 5 because it became slightly gritty after about five minutes, though there were no notable clumps when drinking it.

1st Phorm Opti-Greens 50 is loaded with non-GMO, 100% organic grasses and phytonutrients, is free from artificial ingredients, and has been tested by Informed Choice for harmful or banned substances, so athletes and everyday people can trust that it’s a clean greens powder.

We also love Opti-Greens for its comprehensive assortment of probiotics and enzymes designed to optimize digestion and help relieve occasional bloating³.

The diverse collection of digestive enzymes efficiently breaks down all the macros—fats, carbs, and proteins—while probiotics such as L. plantarum, B. longum, and L. rhamnosus have been shown⁸ to support relief of occasional bloating.

“I always suggest probiotics for my clients with occasional bloating issues, since upper GI issues often originate in the lower GI (colon), where probiotics take effect,” registered dietitian Bob Iafelice says.

I tried Opti-Greens 50 and enjoyed it, giving it a 4 out of 5 for taste. It has a sweet, berry flavor—if you want to get all the benefits of greens without tasting any of the grassiness that normally comes along with it, this would be a good choice for you.

Clocking in at just 75 cents a serving, a 5 out of 5 on our pricing rating scale, Jacked Factory Green Surge is our pick for the most affordable greens powder. It is a formulation of organic greens and antioxidant-containing fruit powders together with probiotics and digestive enzymes. 

“Unlike other greens powders that include every green under the sun, this product focuses on only the most effective superfoods, probiotics, and enzymes,” registered dietitian Bob Iafelice says. “The upshot is a more affordable, yet still effective, greens product.”

Green Surge comes in several flavors—Mixed Berry, Unflavored, Mint Chocolate, Sour Apple, and Lemon Lime. It is flavored with sucralose, which is something to note. 

This certified personal trainer tried the Mixed Berry flavor of Green Surge and thought it was tasty, giving it 4.5 out of 5 stars here. You still get a hint of that grassy, greens taste, which I like, but the berry flavor makes it more easily palatable. 

Inside Green Surge you’ll find the powders of leafy greens like spirulina, spinach leaf, and collards leaf, plus pineapple fruit powder and raspberry fruit powder. You’ll also see green tea leaf extract and Stevia leaf extract. 

Check out our Jacked Factory Green Surge review for more details.

Alani Nu Super Greens powder offers a unique blend of alkalizing greens, antioxidant fruits, and digestive enzymes. It also contains a potent combination of probiotics and inulin, a prebiotic. 

Probiotics⁹ are live microorganisms that, when consumed, can help your body maintain a healthy balance of bacteria in the body, which is good for seasonal wellness. Prebiotics¹⁰ support the growth and activity of probiotics.

“Notably, and unlike many other green products, Alani Nu Super Greens delivers a relatively high dose of probiotics (5 CFU, or colony forming units) that far exceeds the minimum dose found to be effective in studies¹¹ showing benefits of probiotics for a variety of health concerns like occasional diarrhea,” says registered dietitian Bob Iafelice. 

Although there are no flavor options, the greens powder was tasty enough to earn a 4.5 out of 5 on taste. It’s a bit grassy but also fruity. I like it quite a bit—this was the one I reached for first when I had all the greens powders in my fridge.

Beyond the greens blend, Super Greens also has a unique blend of antioxidants and digestive enzymes, and is sweetened with stevia. There aren’t any flavor options, but most reviewers enjoyed the taste. I would agree—the taste is palatable and I reach for this greens powder over many others.

Amazing Grass Greens Energy Blend offers an impressive mix of organic farm fresh greens and fruits like wheat grass, chlorella, acai, and maca root, plus enzymes, prebiotics and probiotics, and a dose of caffeine (85 milligrams) from yerba mate and matcha green tea leaf for better energy levels. This probably won’t give you a boost like a serving of pre-workout, but it’s definitely something.

RELATED: Best Pre-Workout

“These plant sources of caffeine have been shown¹¹ to provide a strong alkaline boost to help counter high acid loads in the body, which may contribute to muscle loss,” says registered dietitian Bob Iafelice.

This certified personal trainer ranks it in my top three on this list for taste. I had the Lemon Lime flavor, which is just the right amount of sweet, and a little tart. A 5 out of 5 on taste. I didn’t notice any boost in terms of energy, but as a habitual coffee drinker, it takes quite a bit to get me going!

RELATED: Best Pre-Workout for Men

Greens Energy Blend also contains vitamin A and vitamin C, which have antioxidant properties, and vitamin K, which is important for bone-building¹. So whether you’re looking for an alternative to your morning or afternoon coffee, or simply just want a boost with your greens, this product could be for you.

Huel Daily Superblend is like a one-stop shop for your micro and macronutrient needs. In addition to having dozens of whole food ingredients, several adaptogens, and probiotics you also get 25 grams of vegan protein per serving. As an added bonus, it also tastes good.

“If you’ve ever put cacao nibs in your smoothie, this tastes like that,” Anthony O’Reilly, a certified nutrition coach and GGR performance editor, says of the Chocolate flavor. “But high-quality nibs, not the cheap stuff. It had a good cacao taste, with a slight green-y taste at the end.” Overall, he rated the flavor a 4.5 out of 5—and that was with water. He thinks it would get a 5 out of 5 if mixed with almond milk.

Consuming enough protein is critical for muscle building, and even maintenance. The recommended daily allowance (RDA) is just .8 grams of protein per kilogram of body weight. For someone who weighs 150 pounds, that’s about 54 grams of protein per day. But keep in mind, the RDA is the minimum amount you need to meet basic nutritional needs. 

According to the American College of Sports Medicine, for someone who is physically active and looking to gain muscle, that number should look like 1.2-1.7 grams of protein per kilogram of body weight. So for that same 150-pound person, you’re looking at about 82 to 115 grams of protein per day. (Need more protein in your diet? Check out our list of the best protein powders).

Huel uses pea protein, which is rich in the essential amino acid leucine. “Leucine is the key amino acid that signals the muscle to make protein¹².”

Whip up a morning shake with this powder blend and know you’re getting a solid dose of protein on top of nutrients from spinach, kale, broccoli, and artichokes. It’s available in Chocolate or Vanilla. It is slightly expensive, at $3.00 per serving, though you are essentially consuming two supplements in one. You can learn more in our Huel review.

Amazing Grass Greens Blend Superfood is packed with probiotics and digestive enzymes that can help with improved digestion, including reducing bloating symptoms.³ This is actually the same vitamin, mineral, and greens blend as the Amazing Grass Greens Energy Blend, just without any of the caffeine.

Longtime fitness writer, expert product tester, and GGR editor Frieda Johnson said she was really impressed with the “original” flavor. “Hands-down the best-tasting greens powder I’ve ever tried,” Frieda says, scoring it a 5 out of 5 on taste. “I wouldn’t necessarily say it tastes good, but it definitely doesn’t taste like straight-up dirt like most greens powders. It’s totally drinkable just mixed with water, but I prefer mixing it with juice.”

Amazon customer reviewers endorse that sentiment, though some said the Berry and Chocolate versions aren’t the best-tasting greens powders on the market.

“I really like that there are no sweeteners or filler ingredients,” Frieda adds.
