Best Greens Powder for Gut Health, Weight Loss, and More (2024)

Greens powders have received a lot of attention over the past few years. As the push for healthy eating continues, searching for the best greens powder supplement can quickly become a daunting task. Most greens powders have over 25 ingredients total, and they all offer different benefits.

As a registered dietitian nutritionist (RDN), I am often asked about the benefits of supplementing with greens powders. I always recommend that my clients still consume whole fruits and vegetables. However, if they want to add a greens powder, I encourage them to do their due diligence and research the supplement to ensure it aligns with their nutrition goals. Lucky for you, I have compiled my research on our top eight picks for the best greens powders around.

How We Chose the Best Greens Powder

Greens powders flood the supplement market now, and they all claim to support various health goals. It is important to be mindful of the brand you roll with and ensure the product you choose contains high-quality ingredients.

To prevent you from wasting your time and money, our Breaking Muscle product review team carefully vets the products we review. We have tested nearly 40 greens powders and ranked them based on flavor, texture, added nutrients, cost, formulation, and any unwanted side effects. After scoring the products on a scale of one to five for each category, we assigned them an overall score and used it to create the list below.

Our Top Picks for the Best Greens Powder

• Best Greens Powder Overall: Athletic Greens AG1
• Best Tasting Greens Powder: Kaged Outlive 100
• Best Greens Powder for Weight Loss: Legion Genesis Greens Supplement
• Best Greens Powder for Gut Health: Transparent Labs Prebiotic Greens
• Best Greens Powder for Bloating: Bulletproof Greens
• Best Organic Greens Powder: Onnit Shroom Tech Greens
• Best Affordable Greens Powder: Jacked Factory Green Surge
• Best Greens Powder for Smoothies: Orgain Organic Superfoods

Best Greens Powder Overall: Athletic Greens AG1

Athletic Greens AG1 is arguably the most popular greens powder on the market. After completing our own research and product testing, we have to agree. This greens powder is vegan and vegetarian-friendly and major allergen-free, making it agreeable for most individuals’ diets. It is non-GMO and not artificially sweetened, colored, flavored, or preserved. 

As a dietitian, I appreciate when manufacturers go through the extra effort of creating an accurate, detail-oriented nutrition facts label. Despite a few proprietary blends, Athletic Greens AG1 is pretty transparent about the ingredients that go into its formulation: probiotics, digestive enzymes, antioxidants, prebiotics, adaptogens, green superfood complexes, phytonutrients, vitamins, and minerals. You will meet your daily recommended amount for vitamin C and vitamin E, two powerful antioxidants, in one serving of AG1.

Consisting of 75 vitamins, minerals, and whole food sourced ingredients in total, Athletic Greens AG1 lives up to its online hype with our product review teams. Despite there being no flavor options, we still rate it at a 4.5 out of 5 stars for flavor. The overall taste is subtle, but there are hints of pineapple and vanilla flavoring.

According to Amanda Dvorak, Breaking Muscle’s Reviews Editor, the powder settles shortly after blending it in a shaker bottle. Also, if you struggle at all with texture, it is a tad gritty and has a foam layer that stays with the drink as you consume it. Amanda rated the solubility 2 out of 5 stars for these reasons.

Best Tasting Greens Powder: Kaged Outlive 100

As a food expert who is routinely researching dietary supplements currently on the market, I can confidently say that it is difficult to find greens powder brands that offer a variety of flavors. However, Kaged Outlive 100 offers Lemon, Berry, and Apple Cinnamon. Not only are the flavors great but they taste great too — making it our top pick for the best-tasting greens powder. 

This greens powder is rated highly by verified customers for taste, ingredient quality, and mixability. Based on 646 reviews on the Kaged website as of this writing, Kaged Outlive 100 holds 4.8 out of 5 stars. The blendability makes it easy to add as a nutrient-packed ingredient to different recipes. Reviewers love the Apple Cinnamon flavor mixed with oatmeal. Try throwing some berries in there, too, so that you capture an extra food group with your breakfast.  

Reviewers have mentioned that it does not have an artificial taste. They also appreciate the affordability compared to other popular greens powders. At around $1.67 per serving, it’s more affordable than AG1 Athletic Greens (which starts at $2.63 per serving).

To keep costs down even further, you can subscribe and save 10 percent on your orders through Kaged’s website. They also offer a fully refunded, 30-day return policy if you are not totally satisfied. According to their customers, the Kaged customer service department is great. 

Best Greens Powder for Weight Loss: Legion Genesis Greens Supplement

The top ingredient in Legion Genesis Greens Supplement is five grams of organic spirulina whole plant powder. Spirulina is a blue-green algae that may help improve lipid panels (specifically cholesterol levels) and reduce body fat, waist circumference, and appetite. (1) Packed with 100 percent naturally occurring ingredients, Legion Genesis Greens Supplement is our top pick for the best greens powder for weight loss. 

Our Breaking Muscle product review team gives this Legion greens powder 4 out of 5 stars for its formulation. The amount of protein per serving (four grams) is impressive for a greens powder supplement, and protein has been linked to sustaining satiety to help curb cravings and manage your weight. (2)

Legion Genesis also contains clinically effective doses of organic spirulina (five grams), dong quai root (1.25 grams), astragalus membranaceus (three grams), and reishi mushroom (three grams). These ingredients are linked to promoting immunity, potentially improving blood flow, and/or possibly decreasing your risk for chronic diseases.

Legion Genesis does not disappoint when it comes to flavor or solubility. We give flavor 4 stars and solubility 4.5 stars. Our review team tried the Acai Berry version and found it to taste like berry-flavored greens, so it meets expectations.

The only reason that solubility did not get a perfect 5-star rating is because of how long we had to physically stir it to get all of the powder to dissolve. Honestly, though, we believe that if we threw it in a blender, it would likely blend just fine.

Best Greens Powder for Gut Health: Transparent Labs Prebiotic Greens

Dietitians and other allied health professionals have found through national surveying that roughly five percent of the population meets the recommended amount of 25 to 30 grams of fiber daily. This is concerning for many reasons, namely the development of chronic illnesses (like heart disease, obesity, and type 2 diabetes), gastrointestinal disorders, and cancers. (3)

So, how can you up your fiber intake? With Transparent Labs Prebiotic Greens! Most prebiotics are a type of non-digestible fiber. Per every 15.5-gram scoop, you will get six grams of dietary fiber. The fiber sources in this greens powder are organic acacia fiber, green banana flour, Jerusalem artichoke fiber, and chicory root. 

A few members of our review team commented that this supplement is particularly good when mixed into fruit juices. They found that the best combo was orange juice and the Peach Mango flavored greens powder. They gave this product 4 out of 5 stars for taste and 4.5 stars for solubility. We found that it mixes with ease, and online customer reviews sing the same tune.

Best Greens Powder for Bloating: Bulletproof Greens

Let your bloating issues be a thing of the past with Bulletproof Greens. This greens powder contains a unique combination of digestive aides to help your digestive system perform well. It also gets bonus points for being one of the most affordable options currently on the market. It costs about $1.67 per serving and is cheaper than Athletic Greens AG1 (which starts at $2.63 per serving) and Onnit Shroom Tech Greens (which costs around $2.00 per serving).

Our product reviewers and online customers agree that you will either love or hate the flavor since it has a strong pineapple taste. We gave it 3 out of 5 stars for taste because we didn’t particularly enjoy it but recognize that people who love pineapple will probably like it.

However, you can always get creative with how you use your greens powder — it does not have to be mixed with only water. Try adding Bulletproof Greens to a fruit smoothie, orange juice, or pineapple popsicle mix. Based on our testing, it blends effortlessly in a shaker bottle or in a glass with a spoon and is easy to incorporate into various liquids. For solubility, we rated it 5 out of 5 stars.

Many customers report zero negative side effects. In fact, most report that it is easily digestible and doesn’t cause gastrointestinal discomfort. Our product tester didn’t experience any significant side effects when she tested Bulletproof Greens. This may be due to the low sodium content of 100 milligrams per serving. This is low compared to other greens powders, which is good because excess sodium intake can lead to water retention. 

In every scoop, you will get two billion colony-forming units (CFU) of the probiotic Bacillus coagulans and a combination of digestive enzymes like amylase and lipase. These ingredients may aid macronutrient digestion and improve clinical symptoms of bloating, especially for those with intestinal diseases like irritable bowel syndrome. (4) Amylase helps break down carbohydrates, and lipase helps to break down fats. (5)

Best Organic Greens Powder: Onnit Shroom Tech Greens

It is not easy to obtain the 100 percent organic certification. Most organic products meet the second-tier standard of having 95 percent of their product derived from organic sources. To obtain the 100 percent organic certification, every single ingredient has to be organically sourced. (6) It is impressive that Onnit has gone to such great lengths to deliver us a non-GMO, major allergen-free, fully organic greens powder.

Delivering half a cup of certified organic vegetables per serving, Onnit Shroom Tech Greens is nutrient-dense to help keep you healthy. The formulation is simple: organic cordyceps, organic reishi, organic lion’s mane, organic kale, organic broccoli, and organic spirulina. These ingredients are packed with vitamin C, vitamin E, vitamin A, and vitamin B6 — all known for potentially being able to support the immune system. (7)

Onnit Shroom Tech Greens blends beautifully but has a strong mushroom flavor. We gave the taste 3 out of 5 stars. Our product tester didn’t enjoy it on its own but said that mixing it with V8 helped improve the taste. That said, if you love mushrooms, we think you’ll like this greens powder.

The powder dissolved completely when we tested it, though, so we gave it 5 out of 5 stars for solubility. This can be a huge plus for anyone who prefers a non-gritty greens power. 

Unlike any of the other greens powders in this review, Onnit Shroom Tech Greens comes in pre-portioned to-go packets. This is convenient for many reasons, but Onnit really has the adventurer in mind. If you are looking for a nutritious companion buddy for your next hike, Shroom Tech Greens has your back.

Best Affordable Greens Powder: Jacked Factory Green Surge

If you have ever looked at Jacked Factory’s product offerings and noticed their reasonable prices, you would not be surprised that the Breaking Muscle team chose it as the best affordable greens powder. For a literal dollar per serving as of this writing, the price of the Green Surge Superfood Powder is unbeatable. It is rare that we give out a perfect 5 out of 5 stars for the price per serving, but Jacked Factory Green Surge made it possible. 

Furthermore, if you order from the Jacked Factory website, you can opt to subscribe and save. This option gets you an additional 15 percent off and free shipping on all recurring orders. There is also a 100 percent hassle-free money-back guarantee if you are not totally happy with your purchase. 

Jacked Factory Green Surge is manufactured in a cGMP-certified factory in the United States. The cGMP certification establishes trust between consumers and manufacturers. By getting this certification, Jacked Factory shows that affordability does not always mean lower quality.

Green Surge is available in Mixed Berry, Unflavored, Mint Chocolate, Sour Apple, and Lemon Lime flavors. Our team gave taste and solubility 4.5 out of 5 stars. We tried the Mixed Berry and still noticed a grassy taste, but the berry flavor made it more palatable. We also had no issues with dissolvability.

Best Greens Powder for Smoothies: Orgain Organic Superfoods

At one point or another, most of us have added a dietary supplement to a smoothie to help enhance the flavor or provide extra nutrients. We are probably most familiar with the addition of whey or plant-based protein powder. However, you can fortify your smoothie even more with super greens like the ones found in Orgain Organic Superfoods. 

Out of 197 reviews on the Orgain website, this greens powder has 4.6 out of 5 stars. Many customers report that it blends effortlessly in their smoothies without changing the flavor of the other ingredients. In other words, neither of the flavors (Original or Berry) is overpowering. A few of the best smoothie combinations listed in their reviews are: 

• Plant protein powder, leafy greens, matcha, coconut almond milk, and a scoop of Orgain Organic Superfoods
• Blueberries, banana, avocado, vanilla yogurt, dairy milk, and a scoop of Orgain Organic Superfoods

Its namesake comes from it being made with two proprietary blends: Orgain Organic 50 Superfoods Blend and Orgain Organic Super Veggies, Super Berries, Super Grasses & Super Foods Blend. The majority of the foods found within the lengthy list of ingredients are certified organic.

Based on our research, this greens powder also gets 5 out of 5 stars for affordability due to its cost of about $1.24 per serving. It’s the second most affordable option on our list. Only Jacked Factory Green Surge, which costs around $1.00 per serving, beats it.

Benefits of Greens Powders

There are many potential benefits to adding a greens powder to your routine. Greens powders may help support overall health by: 

• Improving your digestive tract health 
• Boosting your immune system
• Providing relief from GI discomfort
• Enhancing your energy levels
• Decreasing your risk of micronutrient deficiency 
• Increasing your intake of daily greens

Drawbacks of Greens Powders

As with anything you ingest, there could be potential side effects from greens powders. Based on the feedback from our Breaking Muscle product review team and actual buyer responses, the following are drawbacks you may notice:

• Some have the artificial sweetener sucralose in their formulation, and sucralose may lead to an upset stomach (i.e., stomach cramps and loose bowel movements). This does not dismiss the fact that some users also struggle with plant-based sweeteners such as stevia. 
• Many have directions to slowly implement their use to avoid digestive discomforts like gas and diarrhea. So, it may take a few weeks to build up a tolerance to them to reap their associated health benefits. 
• They are not usually offered in enticing flavors like vanilla or chocolate. Typically, it tastes like a mix of vegetables. Some users find the taste (and even smell) of some greens powder difficult to work past. 

What To Look For in a Greens Powder

There is no one-size-fits-all option for dietary supplements. This is especially true for greens powders due to their wide array of ingredients. Take some time to evaluate what option works best for you to be sure your purchase aligns well with the nutrition targets you hope to meet. Let’s take a look at a few things we recommend you consider before taking the greens powder leap. 

Price

Nobody wants to waste money on a greens powder that does not meet their expectations or help them achieve their health and wellness goals. That’s why affordability is taken into consideration by our product review team. This ensures that we are able to meet you where you are financially and show you that you can get a quality product that costs less.

The greens powders above range from $1.00 to $2.63 per serving, depending on the number and quality of the ingredients, third-party testing, and other factors. Keep in mind that many product websites and even Amazon offer subscription discounts.

Ingredients

Generally speaking, we have found that the more expensive a dietary supplement is per serving, the more quality ingredients it contains. This is not to say that more affordable products are made with cheap ingredients. It just means that you will typically get even more beneficial ingredients in larger quantities with more expensive greens powders.

Verify what the specific benefits are for the ingredients in the greens powder you choose. For those hoping to improve their gut health, try supplementing with a greens powder that has added probiotics and digestive enzymes. If you want to boost your immune system, pick a greens powder that is bountiful in immune-supporting antioxidants like vitamins, A, E, D, and C. (9)

Nutrient Quantity 

The amount of each nutrient varies greatly between different greens powder brands. Try not to get tripped up on marketing tactics without checking out the ingredient label. Make sure there are research-supported doses of each nutrient.

Also, dietary supplements are not regulated by the FDA, making marketing regulation difficult to do. If something “aids in digestion,” check the label for a clinical dose of digestive enzymes. If it “may improve gut health,” check the label for a hearty dose of probiotics and fiber.

When in doubt, verify the product has undergone third-party testing to give you peace of mind that the ingredients are free of contaminants. 

Flavors

Greens powders are not routinely available in different flavors. Usually, they have earthy tastes. However, some may have subtle flavors of berries, pineapple, and/or vanilla. Occasionally, you will find that “unflavored” options are available.

If the taste of greens powders is not becoming, you can mix them into other products. Try adding them to a high-protein zucchini bread, chip dips such as hummus, or fruit smoothies to manipulate the flavor profile and give a nutrient boost to your favorite recipes. 

Who Should Not Consume Greens Powders?

Contrary to what most assume, greens powders are not usually an adequate source of fiber. So these are not meant for people who want a high-fiber supplement.

Avoid these products if you are on a prescription medication that may have a negative interaction. Those on blood thinning medication, like warfarin, need a consistent amount of vitamin K daily to avoid bleeding disorders. Since most greens powders have proprietary blends of ingredients, it is difficult to know the true amount of vitamin K per serving.

Lastly, if you have a gastrointestinal disease that can be easily irritated or lead to mucosal lining inflammation (like Crohn’s disease), you may not tolerate greens powders well. 

Final Thoughts

Keep in mind that this is a guide to greens powders for nutrient supplementation. These products are not meant to replace a healthy diet full of whole fruits and vegetables. Everybody’s body is different. Therefore, we try our best to be inclusive and tackle the different scenarios that people face nutrition-wise: digestive issues, high blood pressure, nutrient deficiencies, weight loss, food allergies, and more. Then, we shed light on how greens powders may help with managing these conditions. 

Greens powders are an awesome way to possibly improve the health of your digestive tract, boost your immune system, relieve GI discomfort (like bloating and gas), enhance energy, and decrease your risk for vitamin and mineral deficiencies. Since the ingredients found in greens powders vary so much from brand to brand, you can depend on our research-supported review above to navigate our favorite options and find what best supports your needs.
