The Best Greens (and Reds) Powders of 2026, Tested and Ranked by a Dietitian Who's Done the Homework
All 13 Products Tested Side by Side
IM8, AG1, Bloom, and 10 more — tested over 2 weeks with the same protocol.
You might be thinking—do I really need a greens (or reds) powder?
I'll be honest: I'm usually the last person to recommend a supplement before you've nailed down the basics of your diet. But let's face it—life gets busy. Even our best intentions don't always lead to a daily serving of greens, reds, or anything that vaguely resembles a vegetable. And that's where a smart powder can step in as a form of nutritional insurance. They are a safety net that help us stay on track and supplement our diets, not replace high-quality, nutritious food!
With so many options on the market, I wanted to cut through the hype and see which powders actually deliver. So, I tested today's most talked-about formulas including AG1, Bloom, and IM8 — and a few others you've probably seen around.

Top 3 picks from 13 products tested over 2 weeks
IM8 Daily Ultimate Essentials Pro
The science-backed newcomer. Co-founded by David Beckham and an advisory board featuring top medical experts from NASA, Cedars-Sinai, and the Mayo Clinic.
AG1 (Athletic Greens)
The industry staple. With massive influencer backing (think: Andrew Huberman, professional athletes), AG1 is often seen as the gold standard in greens powders.
Bloom Nutrition
The viral TikTok favorite. Known for its fruity flavors and aesthetic packaging, Bloom has exploded in popularity, particularly among Gen Z.
There are hundreds of greens and reds powders on the market, all with different ingredients, formulations, and scientific claims. It's no wonder most people feel overwhelmed when trying to pick one! Add in the endless marketing and social media hype, and it becomes even harder to separate fact from fiction. My goal is to cut through the noise and figure out which ones are actually worth your money.
As much as I'd love to play mad scientist and experiment with every greens powder on the market, I just don't have the time! So, I narrowed it down to 13 of the most popular and highly recommended powders on the internet. (I know — 13 is still a lot, but trust me, it was worth it.)
AG1 (Athletic Greens) – The industry staple. With massive influencer backing (think: Andrew Huberman, professional athletes), AG1 is often seen as the gold standard in greens powders.
Bloom – The viral TikTok favorite. Known for its fruity flavors and aesthetic packaging, Bloom has exploded in popularity, particularly among Gen Z.
IM8 – The science-backed newcomer. Co-founded by David Beckham and an advisory board featuring top medical experts from NASA, Cedars-Sinai, and the Mayo Clinic, IM8 takes a research-driven approach.
Organifi – The wellness influencer's go-to. Organifi focuses on organic ingredients and stress-reducing adaptogens.
Amazing Grass – The budget-friendly classic. It's known for its no-frills formula and affordability.
Huel – From the meal replacement experts. It's designed for efficiency and convenience, just like their signature shakes.
Thorne – The practitioner favorite. Thorne is trusted by healthcare professionals and athletes alike.
Ka'Chava – The all-in-one meal replacement. It's packed with protein, fiber, and adaptogens, making it a total meal solution.
Live it Up – The hidden gem. This newer entrant is praised for its clean, simple formula and great taste.
Alaya Naturals – The clean-living choice. With organic ingredients and a transparent label, Alaya appeals to the wellness-conscious crowd.
Vital Supergreen – Designed not just for health, but also to support glowing skin from the inside out.
Primal Greens – An all-inclusive formula that combines probiotics, adaptogens, and digestive enzymes.
WelleCo Super Elixir – The luxury option. They blend wellness and glamour, with premium ingredients and chic branding.
These are the brands you're most likely to come across—whether from social media, online searches, or recommendations from friends.
The Ground Rules
To keep things as scientifically sound as possible, I followed strict criteria when selecting and evaluating each powder:
No "kitchen sink" formulas
If a supplement tried to do too much (think: protein-preworkout-greens hybrids), it got an automatic no. I wanted to test products that were truly focused on greens and reds for optimal nutrition.
Comprehensive formulations only
Single-ingredient supplements didn't make the cut. I prioritized formulas that offered a well-rounded nutrient profile, backed by legitimate research.
Just plain water
No mixing these into fancy smoothie bowls to hide any unpleasant surprises. I wanted to get the 'real' taste of these products, without any other mixes.
The Testing Process
I wanted to make sure the testing process gave each supplement a fair evaluation. This is the testing process I used:
Each morning, I prepared and tested a different supplement in water. I wanted to see for myself how easy they were to prepare.
I tracked mixing behavior, dissolution time, and what it looked like right after mixing and 10 minutes later.
I tasted each supplement within the first 5 minutes of mixing and again 30 minutes later to see how the taste held up over time.
I measured my energy levels 5 times throughout the day - at 9am in the morning before taking the supplement, at noon, at 3pm, and 6pm, and at 9pm before bed.
I reviewed the ingredients, scientific claims, certifications, and research documents for each supplement.
I enlisted my brutally honest husband as a taste tester. If he wrinkled a nose, I took note. (Spoiler alert: he even gave a rare thumbs-up to one of these powders—keep reading!)
My Non-Negotiables in Greens and Reds Supplements
In a market flooded with "premium" promises, not all formulas are created equal. Celebrity endorsements can be fun—but it's the PhD-backed advisory boards and legitimate research that matter more.
The Must-Have Checklist
Taste is perhaps the biggest deal-breaker of them all. Because if you don't like it, you won't make a habit of drinking it. Making it an expensive waste of space in your pantry. But I'm happy to report that my top pick from a nutrition standpoint was also my taste panel's favorite in terms of flavor!
Finally, I compared each formula's price-per-serving (some brands are sneaky with their serving sizes) and assessed real-world bioavailability. Let's jump into it, and feel free to leave any comments if you have tried any of these brands!

What the data actually shows
Here's what really caught my attention as a dietitian: IM8 actually ran a 12-week randomized controlled clinical trial through the San Francisco Research Institute. That's rare in this space — most brands rely on ingredient-level studies, not product-level trials. Here's what they found:
reported more energy
better gut health
improved sleep quality
sharper focus
For context: 649K+ customers have purchased IM8, totaling over 19M servings. It's NSF Certified for Sport (same certification used by professional athletes).
Pros
- 90 premium, clinically-dosed ingredients
- Formulated by top scientists (NASA, Mayo Clinic, Cedars-Sinai)
- Backed by third-party clinical trials
- Delicious berry and açai flavor
- All-natural, nothing synthetic
- Complete transparency (no proprietary blends)
- Includes CoQ10, MSM at clinical doses
- Comprehensive probiotic blend
- Enhanced bioavailability
- Made in USA in FDA-registered facility
- Free shipping
- 30-day money-back guarantee
- Noticeable results within days
Cons
- Only available online
- High demand can lead to stock issues
- Thin powder
What I Love
IM8 actually tastes and smells good. The berry and açai flavor is genuinely enjoyable — not the "hold your nose and chug" experience I've had with other powders. Beyond the flavor, I felt really great when drinking this as part of my morning routine! More energy, better focus throughout the day, and noticeably improved digestion. If you're looking for an easy, science-backed way to support your gut, immunity, and overall health, IM8 is a fantastic daily ritual.
IM8 is co-founded by David Beckham, but he has an incredibly solid team of scientists creating the product, including Dr. Dawn Musallem, Integrative Oncologist from Mayo Clinic, Prof. Suzanne Devkota, Director of Microbiome from Cedars-Sinai, and even the Former Chief Scientist of NASA. Seeing this level of scientific backing from academia, medical professionals and with clinical trials and 3rd party testing for a supplement is rare, so I am confident the formulation is as optimized as it could be.
What Could Be Better
IM8 is packed with premium, clinically dosed ingredients, but that level of quality comes at a price—it's on the higher end at $79 per month. That said, when I compared it to the cost of buying multiple separate supplements (probiotics, greens, antioxidants, etc.), it ended up being much cheaper than buying all the components separately!
It is also one of the thinnest powders, which can be good and bad. It mixed easily, but it also makes it a tad messier, and I often had to wipe off stray powder from my countertops.
Another thing to note: it's only available online, and because it's in high demand, it sometimes sells out. If you want to make it a daily habit, I'd recommend signing up for a subscription to avoid stock issues.
Ingredient Breakdown
IM8 Daily Ultimate Essentials Pro is packed with 90 premium ingredients carefully formulated to target nine key areas of health. Here's a closer look at some of the standout components:
CoQ10 (100mg): Supports cellular energy production and heart health, with a clinical dose that's 20% higher than most daily supplements.
MSM (1,500mg): Promotes joint health and muscle recovery, with an anti-inflammatory boost for active lifestyles.
Vitamin D3 (100% DV): Essential for bone health, immune function, and hormone regulation, a common deficiency in most diets.
B-Vitamins Complex (B6, B12, Folate – 150% DV): Provides sustained energy and supports brain health, with bioavailable methylated forms for optimal absorption.
Zinc (100% DV) and Magnesium (125% DV): Crucial for immune support, sleep quality, and muscle recovery, included in bioavailable forms.
Superfood and Adaptogen Blend: A powerful combination of green tea, açai, pomegranate, and sea moss offers antioxidant protection, helps reduce inflammation, and boosts metabolism.
Prebiotics, Probiotics, and Postbiotics: Includes clinically validated strains like Lactobacillus acidophilus and Bifidobacterium lactis, as well as Butyrate for gut comfort and nutrient absorption.
Electrolyte Hydration Blend: A mix of sodium, potassium, and magnesium ensures balanced hydration without added sugars or fillers.
IM8 Daily Ultimate Essentials Pro — my top pick for 2026
AG1: The OG of Greens Powders
Pros
- Convenient all-in-one formula
- Wide variety of ingredients
- Diverse health benefits
- Endorsed by celebrities and athletes
- Vegan, gluten free, dairy-free
- 30-day money-back guarantee
- Tastes decent for a greens powder
- Mixes well, no clumps
- NSF Certified for Sport
Cons
- Doesn't disclose exact dosages (proprietary blends)
- Uses synthetic vitamins instead of bioavailable forms
- Probiotic count is unclear
- May cause bloating, nausea, or diarrhea in some users
- Potential interactions with common medications
- Not recommended for pregnant or breastfeeding individuals
- Expensive at $99/month
- Contains stevia, which some people dislike
What I Love
It's no wonder AG1 has been dominating the greens space for a decade: it's an impressive product and there has been a lot of investment in making sure the experience (think the website and Welcome Kit) give you the best possible first impression.
So, AG1 has a lot going for it, and if you're looking for a solid greens powder and don't mind paying a premium, here's what I liked.
First off, it's a good all-in-one formula, combining greens, adaptogens, probiotics, and vitamins into a single scoop (however, not in clinically recommended doses, we will get into that!). It also includes spirulina, chlorella, and wheatgrass—all great sources of phytonutrients and antioxidants. It also includes prebiotics and probiotics for gut health, which is a plus, and I did see some improvement in my bloating and digestion after taking it in the morning!
Taste-wise, most greens powders taste like blended lawn clippings. AG1 has a smooth, slightly tropical flavor with a hint of vanilla and pineapple. It's one of the more drinkable options out there (especially compared to the ultra-earthy formulas), but I personally didn't enjoy it enough to see myself easily incorporating it into my daily routine.
What Could Be Better
While AG1 remains one of the most talked-about greens powders on the market, recent health reviews have raised new concerns—particularly around potential side effects like digestive discomfort (bloating, nausea, diarrhea) and ingredient interactions with common medications like blood thinners and antidepressants. Experts also caution against its use for pregnant or breastfeeding individuals and those with autoimmune or kidney conditions.
There is still a lot of hype around AG1, with endorsements from professional athletes, fitness coaches, and influencers like Andrew Huberman, which often leads to the question of how much of the premium price (US$99 per month) is worth it—and how much of it is just marketing.
There are other cons that can't be ignored. The vitamins and minerals are from synthetic sources rather than naturally derived or bioavailable forms. For example, the vitamin B12 is cyanocobalamin (less absorbable than methylcobalamin).
The biggest red flag for me is that AG1 hides its ingredient dosages behind proprietary blends. That means you don't actually know how much of each nutrient you're getting. They list all the ingredients, but the label doesn't break down the exact amounts—making it impossible to assess whether you're getting clinically effective doses or potentially overdoing others.
AG1 is still a very good greens powder—it's convenient, doesn't taste bad, and includes a mix of greens, probiotics, and adaptogens. But in my humble opinion, with the new safety concerns and a lack of transparency, there are better options out there.
Heavy Metals Comparison: AG1 vs IM8
Independent third-party testing revealed a significant difference in heavy metal content between these two products. IM8 tested for ~90% lower arsenic and cadmium levels compared to AG1.

Bloom: The TikTok Favorite That's More About Flavor Than Function
Pros
- Most variety of flavors
- Focus on bloating
- Vegan, gluten free, dairy-free
- Reasonably priced
- Available offline at major retailers
- Contains probiotics and digestive enzymes
Cons
- Little ingredient transparency
- Clumpy and doesn't mix well
- No vitamins or minerals listed
- Not organic
- Contains stevia, which some people dislike
What I Love
One of the things I love most about Bloom is that it's an easily accessible option due to being in major retailers like Target and Amazon.
Formula-wise, it stands out with its low-calorie content and a focus on pre-and probiotic enzymes designed to beat bloating. It has a well-rounded ingredient list with a variety of superfoods like barley grass, spirulina, and organic flaxseed.
If you're a fan of a sweeter greens powder, then you will enjoy this formula! They have a variety of fruity flavors like Mango and Kiwi. I tried the Orange Passionfruit, but it was a bit too sweet for my liking. It's also a more affordable option at just US$40 for 30 servings.
What Could Be Better
Bloom has its shortcomings, especially in the transparency department. First off, most greens powders clearly outline their vitamin and mineral content, but Bloom doesn't. Without this information, it's hard to tell how much actual nutrition you're getting. And while Bloom does contain a wide variety of greens, the dosages aren't listed—meaning there's no way to know if you're getting clinically effective amounts or just trace amounts for label appeal. From what I can see, the product has also not been third-party tested.
While the taste might appeal to some, it was a tad too sweet for me, and the powder was incredibly clumpy and annoying to mix. I noticed it still had clumps on the surface even after using an electric whisk.
All in all, it feels more like a wellness drink rather than a supplement, and it doesn't compare to IM8's research-backed formulation or AG1's more established ingredient profile.

The Verdict on the Top 3
IM8 leads in 10 out of 12 categories, including third-party testing (NSF Certified for Sport), ingredient transparency, clinical dosing, and heavy metal testing. AG1 earns the best money-back guarantee at 90 days. Bloom is the most affordable option at $40/mo but lacks the nutritional depth and third-party validation of the other two.
Why I Chose IM8
After extensive testing of premium supplements, I'm so happy that I found one that checked all my boxes. First, IM8 has a wide range of high-quality, nutritious ingredients in bioavailable forms and in clinically recommended doses. Second, it supports a wide range of health benefits, from energy to digestion to immunity. And third, it actually tastes delicious and is enjoyable to drink – which makes it much easier to make a habit of drinking daily!
At $112 $79 on the 90-day subscription (or $89/month with no commitment), IM8 sits in the premium category. But when you consider that it's replacing what would normally be a $200+ monthly supplement stack (I did the math), while providing higher doses of key nutrients than competitors like AG1 ($99), the value becomes clear. Plus, you're getting what might be the most sophisticated supplement formulation currently on the market - backed by a scientific advisory board that reads like a who's who of medical research.
I've also been already introducing it to my clients, which I would not be doing if I didn't believe in the value of this supplement on optimal health and longevity! They are absolutely loving it so far. The feedback I've received is incredible – they are no longer needing afternoon naps, their bowel movements are now regular, and their joints are even feeling so much better.
Remember, supplements don't replace whole foods and a balanced diet, but if you're looking to always perform at your best, IM8 will ensure you get everything your body needs and more.
