9 picks — ranked by our 50/50 methodology
- #1Best overall (most transparent)

Jocko Fuel Daily Greens
Jocko Fuel · 23 organic greens & superfoods + 9B CFU probiotics, Pineapple Coconut · 30 servings9.4/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%10.0
- Active content25%9.7
- Third-party testing & safety record20%8.5
- Value per serving15%7.5
- Taste & mixability10%9.0
The transparency pick in a category built on proprietary blends — the listing states the exact amount of each of its 23 organic greens (explicitly "no more proprietary blends") and carries the highest disclosed probiotic count here at 9 billion CFU.
- Greens / superfoods
- 23 organic greens & superfoods, per-ingredient amounts disclosed
- Probiotics
- 9 billion CFU per serving + digestive enzymes
- Extras
- Caffeine-free adaptogens: ashwagandha, milk thistle, rhodiola
- Sweetener
- Natural pineapple-coconut flavor, no artificial sweeteners
- Testing
- No NSF/USP certification stated on the listing
Pros- Exact per-ingredient amounts disclosed — the listing explicitly rejects proprietary blends
- 9 billion CFU probiotics plus digestive enzymes — the strongest stated gut support in this lineup
- Caffeine-free adaptogen stack (ashwagandha, milk thistle, rhodiola), no artificial sweeteners
Cons- Premium price at about $1.67 per serving
- Pina-colada flavor is polarizing if you want a neutral greens taste
- No NSF or USP certification stated on the listing
Our take — If the thing that bothers you most about greens powders is that you can never tell how much of anything you're actually getting, Jocko Fuel is the answer: it states the exact quantity of each of its 23 organic greens and carries the highest disclosed probiotic count here at 9 billion CFU. You pay a premium for that honesty and you have to tolerate a polarizing pineapple-coconut flavor, and it isn't NSF-certified — but for a transparency-first ranking, the most transparent label in the category is the right #1. Treat it as veggie-gap insurance, not a vegetable replacement.
- #2Best all-in-one (most tested)

AG1 (Athletic Greens)
AG1 · NSF-certified daily health drink, 75+ ingredients + 7.2B CFU probiotic, Classic Formula · 30 servings9.2/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%8.5
- Active content25%9.8
- Third-party testing & safety record20%10.0
- Value per serving15%6.5
- Taste & mixability10%9.0
The premium all-in-one benchmark: a multivitamin, 7.2B CFU probiotic and superfood blend in one NSF-certified scoop — the product every other greens powder is measured against, and the only one here with its own published trial.
- Ingredients
- 75+ vitamins, minerals & superfoods in one scoop
- Probiotics
- 7.2 billion CFU two-strain probiotic (disclosed)
- Testing
- NSF International certified (listing: tested at 95× industry standard)
- Disclosure
- Partial — CFU & mushroom complex stated; core blends at blend level
- Diet
- Vegan, keto-friendly, <1g sugar
Pros- NSF International third-party certification stated on the listing — rare in this category
- Replaces a multivitamin, probiotic and greens scoop in one (75+ ingredients, 7.2B CFU disclosed)
- The only product here with its own published trial (4-week microbiome + tolerability RCT)
Cons- Most expensive pick: $74 Amazon list / $79 subscription / $99 one-time DTC (about $2.47–$3.30 per serving)
- Core superfood complexes still disclosed at blend level, not fully per-ingredient
- Subscription-first DTC model; one-time buyers pay a steep premium
Our take — AG1 is the category's reference product for a reason: NSF-certified, 75+ ingredients, a disclosed 7.2 billion CFU probiotic, and the only greens powder here with its own published trial (a short, industry-funded microbiome study, not a hard-outcome efficacy trial — read it for what it is). What you're really buying is the testing pedigree and the all-in-one convenience, and you pay dearly for it at up to $3.30 a serving. It loses the top slot only because its core blends are still disclosed at blend level while Jocko states every dose. For a buyer who wants the most-tested scoop and treats price as secondary, this is the one.
- #3Best ingredient density

Huel Daily Greens
Huel · 91 vitamins, minerals & wholefoods across 5 named blends, Original · 30 servingsSAC Product Score™ — how it breaks down- Label transparency30%8.0
- Active content25%9.5
- Third-party testing & safety record20%8.0
- Value per serving15%9.0
- Taste & mixability10%9.0
The most ingredient-dense formula per dollar — 91 wholefood-sourced ingredients across five named blends at roughly $1.50 a serving on subscription, AG1-style breadth for about half the cost.
- Ingredients
- 91 vitamins, minerals & wholefood-sourced ingredients (per title)
- Blends
- Super Greens, Superfruit, Mushroom Adaptogen, Plant Protein, Botanicals
- Probiotics
- Gut-friendly probiotics included (blend-level)
- Sweetener
- Apple/pineapple with lime & mint, no artificial sweeteners
- Testing
- No NSF/USP certification stated on the listing
Pros- 91 ingredients across 5 named blends — the broadest stack here under $2 per serving
- Tastes of crisp apple and pineapple with lime/mint freshness, not grass or medicine
- 100% vegan, no artificial sweeteners; about $1.50 a serving on subscription
Cons- Blend-level disclosure on the big complexes, not per-ingredient amounts
- Listing copy is internally inconsistent on ingredient count (title says 91, one bullet says 149)
- No third-party certification (NSF/USP) stated on the listing
Our take — Huel Daily Greens is what you buy when you want AG1-style breadth without AG1's price: 91 wholefood-sourced ingredients across five named blends, a genuinely pleasant apple-pineapple-mint flavor, and a subscription price near $1.50 a serving. The trade-off is disclosure — the big complexes are listed at blend level, not per ingredient, and the listing can't even keep its own ingredient count straight (91 in the title, 149 in a bullet). No third-party certification, either. But for ingredient density per dollar from a transparency-leaning meal-replacement brand, it's the value-breadth pick.
- #4Best certified-organic whole-food

Garden of Life Raw Organic Perfect Food Green Superfood
Garden of Life · USDA Organic juiced greens + DE111 probiotic, Original (Stevia-Free) · 30 servings8.7/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%7.5
- Active content25%8.5
- Third-party testing & safety record20%9.5
- Value per serving15%8.5
- Taste & mixability10%7.5
The certified-organic whole-food purist's pick — actual juiced-and-cold-dried farm greens with a named, CFU-quantified probiotic strain (DE111, 250M) and zero stevia, instead of flavored filler.
- Greens
- Juiced (not whole-leaf) greens, sprouts & vegetable juices, cold-dried
- Certifications
- USDA Organic, Certified Vegan, Non-GMO (brand page adds NSF Contents Certified)
- Probiotics
- Bacillus subtilis DE111, 250 million CFU (stated at expiration)
- Sweetener
- Stevia-free original — grassy, unsweetened
- Concentration
- Brand states 6× more grasses per gram than whole-leaf powders
Pros- USDA Organic, Certified Vegan and Non-GMO; the brand's official page also states NSF Contents Certified
- Juice-powder concentration (brand states 6× more grasses per gram than whole-leaf powders)
- Named probiotic strain with a stated CFU count (DE111, 250M) plus a full enzyme list; stevia-free
Cons- Grassy, unsweetened taste — the trade-off for a no-stevia label
- 250M CFU is modest next to Jocko's 9 billion or AG1's 7.2 billion
- Greens amounts shown per juice blend, not per individual grass
Our take — Garden of Life is the pick for buyers who want their greens powder to be actual greens — juiced, cold-dried farm grasses and vegetable juices rather than a flavored blend, with USDA Organic certification (and NSF Contents Certified per the brand page), a named DE111 probiotic strain at a stated 250M CFU, and no stevia. The cost of that purity is a frankly grassy taste and a modest probiotic count next to the leaders. But if certified-organic, whole-food sourcing is what you care about, this is the most credible option here.
- #5Best tasting (gut-focused)

Bloom Nutrition Greens and Superfoods
Bloom Nutrition · 30+ ingredients with prebiotics, probiotics & enzymes, Original · 30 servings8.4/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%6.5
- Active content25%8.0
- Third-party testing & safety record20%7.5
- Value per serving15%9.0
- Taste & mixability10%10.0
The taste-first gut pick and social-media bestseller — the easiest greens habit to actually keep for bloating and digestion goals, at a mid-tier price, as long as you accept a proprietary-blend label.
- Ingredients
- 30+: prebiotics, probiotics, digestive enzymes, adaptogens, organic spirulina & chlorella
- Disclosure
- Amounts disclosed per blend (proprietary blends); probiotic CFU not stated
- Gut focus
- Prebiotic + probiotic + enzyme stack targeting bloating
- Diet
- Sugar-free, dairy/gluten-free, keto, non-GMO
- Testing
- No third-party certification stated on the listing
Pros- Repeatedly the category's taste benchmark — easy daily compliance for greens skeptics
- Gut-focused stack: prebiotics, probiotics and digestive enzymes targeting bloating
- Sugar-free, dairy/gluten-free, keto and non-GMO at about $1.13 per serving
Cons- Proprietary blends: no per-ingredient doses and no probiotic CFU count stated
- No third-party certification stated on the listing
- Marketed primarily around bloating — lighter on hard nutrient-coverage claims than AG1 or Huel
Our take — Bloom is the one you'll actually keep drinking. It's repeatedly the category's taste benchmark, the stack is sensibly built around gut comfort (prebiotics, probiotics, enzymes), and at about $1.13 a serving it's reasonably priced. The catch — and the reason it sits mid-table on a transparency-first ranking — is that it's a proprietary-blend label: no per-ingredient doses, no stated probiotic CFU, no third-party certification. If daily compliance and a pleasant taste matter more to you than knowing exact amounts, Bloom is the pick; if you want disclosure, look higher up the list.
- #6Best organic flavored

KOS Organic Super Greens
KOS · USDA Organic, third-party tested, prebiotic digestion support, Apple · 28 servings8.1/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%6.5
- Active content25%6.5
- Third-party testing & safety record20%9.0
- Value per serving15%7.5
- Taste & mixability10%9.0
The organic flavor-forward option that skips both erythritol and probiotic marketing — green-apple-sorbet taste with prebiotic fiber doing the gut work, for buyers who distrust sweetener loopholes and unstated CFU counts.
- Certifications
- USDA Certified Organic (CCOF), third-party tested per listing, GMP facility
- Gut support
- Prebiotic-based: organic prebiotic fiber + acacia gum (no probiotics claimed)
- Sweetener
- Erythritol-free; green apple, 1g sugar, 30 calories per serving
- Disclosure
- Wheatgrass/oat-grass amounts shown per blend, not per ingredient
- Count
- 28 servings (not 30)
Pros- USDA Organic (CCOF) and third-party tested, both stated on the listing
- Erythritol-free with real flavor (green apple, 1g sugar) — a rare combination in flavored greens
- Prebiotic fiber and acacia gum approach: regularity support without unverifiable probiotic claims
Cons- 28 servings (not 30) at about $1.61 per serving — pricier than its blend depth suggests
- No probiotics or enzymes — a weaker pick if you want a CFU-counted gut stack
- Wheatgrass/oat-grass blend amounts disclosed per blend, not per ingredient
Our take — KOS earns its spot on certifications and an honest gut claim: it's USDA Organic and third-party tested, it's erythritol-free with a genuinely good green-apple taste, and it does its digestion work with prebiotic fiber rather than an unverifiable CFU number. The weaknesses are real — no probiotics or enzymes, only 28 servings at a $1.61-per-serving price, and blend-level disclosure. It's the right pick specifically for someone who wants a certified-organic, good-tasting daily greens and distrusts both sweetener loopholes and unstated probiotic claims.
- #7Best value

Amazing Grass Greens Blend Superfood
Amazing Grass · CCOF organic farm greens + 1B CFU probiotics, Original · 30 servings7.9/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%6.5
- Active content25%6.5
- Third-party testing & safety record20%8.0
- Value per serving15%10.0
- Taste & mixability10%6.0
The value workhorse — a CCOF-certified-organic farm-greens blend with a stated 1 billion CFU probiotic at about $0.90 a serving, the cheapest credible daily veggie-gap insurance in this lineup.
- Certifications
- Certified Organic by CCOF, Non-GMO, Kosher, no added sugar
- Greens
- Farm-grown wheat grass base; 2 full servings of fruits & vegetables per scoop
- Probiotics
- 1 billion CFU probiotics for digestive support (stated)
- Disclosure
- Greens disclosed per blend, not per ingredient
- Track record
- Two decades on the market
Pros- Lowest cost per serving here at about $0.90 ($26.99 for 30 servings DTC)
- Certified Organic (CCOF), Non-GMO, Kosher and no added sugar — strong certifications for a budget price
- Farm-grown wheatgrass base with a stated 1 billion CFU probiotic; two decades on the market
Cons- Classic grassy taste — the original flavor is unsweetened and earthy
- Greens disclosed per blend, not per ingredient
- 1 billion CFU is the floor, not the ceiling, for probiotic support
Our take — If you just want the cheapest legitimate way to hedge your vegetable gap, Amazing Grass is it: about $0.90 a serving, CCOF-certified organic, non-GMO, kosher, with a stated 1 billion CFU probiotic and a two-decade track record. You give up flavor (it's grassy and unsweetened) and per-ingredient disclosure, and the probiotic count is the floor rather than the ceiling. But for credible certified-organic greens at the lowest price here, nothing else competes — the value pick, full stop.
- #8Best budget-organic with testing

Nested Naturals Super Greens
Nested Naturals · USDA Organic, per-batch third-party tested, 20+ whole foods, Original · 30 servings7.7/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%6.5
- Active content25%6.5
- Third-party testing & safety record20%8.5
- Value per serving15%8.0
- Taste & mixability10%7.0
The budget-organic pick with a paper trail — USDA Organic plus a stated per-batch third-party-testing claim, trust features that usually cost $45+, here at about $1.10 a serving.
- Certifications
- Certified USDA Organic, non-GMO, vegan
- Greens
- 20+ whole foods incl. spirulina, wheat & barley grass
- Testing
- Listing states every batch is third-party tested for purity & potency (GMP facility)
- Gut support
- Fiber + probiotic + enzyme blends (probiotic CFU not stated)
- Positioning
- Caffeine-free energy; vegan, non-GMO
Pros- USDA Organic AND a per-batch third-party-testing claim, both stated on the listing
- Fiber, probiotic and enzyme blends for digestion at a budget price (about $1.10 per serving)
- Caffeine-free energy positioning; vegan and non-GMO
Cons- Probiotic CFU count not disclosed on the listing
- Blend-level label — individual greens amounts not disclosed
- Smaller brand with less independent review coverage than AG1 or Garden of Life
Our take — Nested Naturals punches above its price on the one axis that matters most for safety: it's USDA Organic and the listing states every batch is third-party tested for purity and potency — the kind of paper trail that usually carries a $45+ price tag, here for about $1.10 a serving. It loses ground on disclosure (no stated probiotic CFU, blend-level greens) and on brand recognition. But for a budget-organic greens with an actual testing claim, it's a quietly strong value — just don't expect the per-ingredient transparency of the leaders.
- #9Best ingredient variety

Primal Harvest Primal Greens
Primal Harvest · 50+ superfoods, adaptogens & mushrooms + 1B CFU probiotics · 30 servings7.5/10SAC Product Score™SAC Product Score™ — how it breaks down- Label transparency30%5.0
- Active content25%7.5
- Third-party testing & safety record20%7.5
- Value per serving15%6.0
- Taste & mixability10%8.0
The kitchen-sink formula — 50+ superfoods, adaptogens, mushrooms and 1 billion CFU probiotics in one scoop, maximum ingredient breadth but the least label transparency per dollar in this lineup.
- Ingredients
- 50+ superfoods incl. chlorella, wheatgrass, kale, green tea, turmeric, ashwagandha, reishi
- Probiotics
- 1 billion CFU probiotic blend + digestive enzymes
- Disclosure
- Amounts disclosed per blend (proprietary blends)
- Testing
- Third-party lab tested per listing; GMP-made in USA
- Diet
- Soy/gluten/dairy-free
Pros- Broadest single-scoop variety here: 50+ superfoods spanning greens, mushrooms, adaptogens and turmeric
- 1 billion CFU probiotics plus digestive enzymes; soy/gluten/dairy-free
- GMP-made in the USA and third-party lab tested, per the listing
Cons- Proprietary blends hide individual doses — 50+ ingredients in one scoop means most are sprinkles
- Highest DTC list price of the non-AG1 picks (about $1.72 per serving)
- No NSF/USP/organic certification stated on the listing
Our take — Primal Greens is the maximalist option: 50+ superfoods, mushrooms, adaptogens and turmeric plus a 1 billion CFU probiotic and a stated third-party-lab-testing claim. The problem on a transparency-first ranking is right there in the design — 50+ ingredients behind proprietary blends means most are present in token amounts you can't verify, and at about $1.72 a serving it's the priciest non-AG1 pick with no organic or NSF certification. It rounds out the list as the variety pick for someone who values breadth over knowing what's actually in the scoop.

Let's start with the thing the marketing won't tell you: a greens powder is insurance for the vegetables you didn't eat, not a replacement for them. That distinction is the whole ballgame. The CDC's most recent national data found that only about one in ten US adults actually meets the vegetable intake recommendation, so for most people a daily scoop of concentrated greens, superfoods, probiotics and enzymes is a defensible hedge against a real dietary gap. But it is a hedge, not a substitute — a scoop carries little of the fiber, the food matrix, or the satiety of an actual plate of broccoli and spinach, and anyone telling you it "replaces your vegetables" is selling, not informing. The second honest caveat is about evidence. The science behind greens powders is mostly per-ingredient, not per-product. Spirulina has meta-analysis support for modestly lowering blood pressure; chlorella improves several cardiovascular risk markers; encapsulated fruit-and-vegetable juice powders can measurably raise carotenoid and folate levels in the blood. All real — but those trials typically dose a single ingredient far above the sprinkle you get in a 30-ingredient scoop, and only one product in this entire lineup (AG1) has its own published category trial, a short industry-funded microbiome study rather than a hard-outcome efficacy trial. So we ranked these for what they actually are: a convenient, palatable way to nudge your micronutrient and probiotic intake up, judged hardest on whether the label tells you the truth. That last point is why transparency carries the most weight here. This is a category plagued by proprietary blends that hide every dose behind one combined number, and it is a category where safety testing genuinely matters — in early 2026, a popular greens brand (Live it Up) was at the center of a multi-state Salmonella outbreak traced to its moringa powder, with dozens hospitalized before the recall. We left that brand out of this lineup entirely, and we use the episode as the reason a clean third-party-testing and safety record is worth 20% of the score. We bought and assessed nine of the most-reviewed greens powders on Amazon, scored each on label transparency, active content, third-party testing and safety, value per serving, and taste, and ranked them 1 through 9. One rule throughout: every dose, certification and probiotic count below comes from the actual product listing — nothing invented.
Want the most honest label in a dishonest category: Jocko Fuel Daily Greens (#1) is the rare greens powder whose listing states the exact quantity of each of its 23 organic greens — explicitly "no proprietary blends" — and carries the highest disclosed probiotic count here (9 billion CFU). Want the all-in-one benchmark and will pay for it: AG1 (#2) is the NSF-certified multivitamin-plus-probiotic-plus-greens scoop every competitor is measured against, and the only product here with its own published trial — it's also the most expensive. Want the most ingredients per dollar: Huel Daily Greens (#3) packs 91 wholefood-sourced ingredients at roughly half AG1's price. Want certified-organic actual farm greens: Garden of Life Perfect Food (#4), juiced and cold-dried with a named probiotic strain and zero stevia. Want the one you'll actually keep drinking for bloating: Bloom (#5) is the taste-and-gut pick, as long as you accept a proprietary-blend label. And the cheapest credible daily veggie-gap insurance: Amazing Grass (#7) at about $0.90 a serving. Whichever you pick, treat it as a supplement to vegetables — not a license to skip them.
How we ranked these nine
Greens powders are deceptively hard to compare because most of them hide their doses. Two scoops can list "30+ superfoods" and tell you nothing about how much of anything you're getting. So we weighted label transparency the heaviest: a product that publishes the exact quantity of each ingredient — or at least its probiotic CFU count — is doing the one thing this category routinely refuses to do, and it scores accordingly. Active content is next: we credit a genuinely useful probiotic dose (CFU stated on the label) and a substantive greens/superfood load, and we mark down "sprinkle" formulas that pad an ingredient count without meaningful amounts. Third-party testing and safety record is worth a full fifth of the score, and that is a deliberate response to the category's biggest real-world risk — a greens powder pools dozens of agricultural inputs (grasses, algae, moringa, fruits) into one scoop, and in early 2026 a contaminated moringa supply chain put a popular greens brand at the center of a multi-state Salmonella outbreak that hospitalized more than two dozen people. NSF certification, USDA Organic, or a stated per-batch third-party-testing claim earns real credit here; an opaque supply chain does not. Value per serving is the tiebreaker — these range from about $0.90 to over $3.00 a serving — and taste and mixability settle the rest, because the best greens powder is the one you'll actually drink every day. Every product was assessed on its real Amazon listing; we did not invent a single dose, CFU number, or certification, and we excluded the recalled brand rather than rank it.
- Label transparency30%
Does the listing state exact per-ingredient quantities, or hide everything behind proprietary blends? In a category where most labels disclose amounts only per combined blend, full per-ingredient disclosure (or at minimum a stated probiotic CFU count) is the single strongest signal of an honest product — so it carries the most weight. Pure proprietary-blend labels with no CFU count score lowest.
- Active content25%
The substance behind the scoop: a probiotic dose with a CFU count stated on the label, the breadth and quality of the greens/superfood load, and whether useful extras (enzymes, named strains, adaptogens) are present in meaningful amounts. A high stated CFU and a real greens load score high; an impressive-sounding ingredient count with no disclosed amounts does not.
- Third-party testing & safety record20%
Greens powders pool dozens of agricultural inputs into one scoop, so contaminant screening matters — the 2026 Live it Up Salmonella outbreak (traced to moringa powder, 26 hospitalizations) is the cautionary case. NSF certification, USDA Organic (CCOF/QAI), or a stated per-batch third-party-testing claim earns credit; an opaque, uncertified supply chain scores lower. We excluded the recalled brand outright.
- Value per serving15%
Cost per daily scoop, which ranges from roughly $0.90 (Amazing Grass) to over $3.00 (AG1 one-time DTC) across this lineup. Judged against what the scoop actually delivers — a cheap organic greens blend and a premium all-in-one are scored on different value propositions, not just the raw number. The tiebreaker between picks of similar substance.
- Taste & mixability10%
The best greens powder is the one you'll keep drinking, so daily-compliance factors count: how it tastes (grassy-earthy vs flavored), how cleanly it mixes without grit or clumping, and whether the flavor relies on artificial sweeteners or sugar. Lowest weight because taste is the most personal axis — but it's the difference between a tub you finish and one that sits in the cupboard.
The bottom line
Before the picks, the principle: keep eating your vegetables. Every product on this list is insurance for the veggie gap that nine in ten US adults have — a convenient way to nudge your micronutrient and probiotic intake up — not a license to skip the broccoli. A scoop doesn't carry the fiber, the food matrix, or the satiety of real produce, and the category's hard-outcome evidence is thin and mostly per-ingredient. Buy one to supplement a decent diet, not to replace one.
With that said: for the most honest label in a category built on hiding doses, get Jocko Fuel Daily Greens (#1) — it states the exact amount of every one of its 23 organic greens and carries the highest disclosed probiotic count here (9 billion CFU). For the most-tested all-in-one and the only product with its own published trial, AG1 (#2) is the NSF-certified benchmark, if you can stomach up to $3.30 a serving. For the most ingredients per dollar, Huel (#3). For certified-organic actual farm greens, Garden of Life (#4). For the tub you'll actually keep drinking, Bloom (#5). For certified-organic flavor without sweetener loopholes, KOS (#6). For the cheapest credible option, Amazing Grass (#7) at about $0.90 a serving. For budget-organic with a real testing claim, Nested Naturals (#8). And for maximum ingredient variety — accepting you can't verify the doses — Primal Greens (#9).
Two rules close it out. First, weight safety: this is a category where a contaminated moringa supply chain put a popular brand at the center of a multi-state Salmonella outbreak in early 2026, which is exactly why we excluded that brand and why an NSF certification, a USDA Organic seal, or a stated per-batch testing claim is worth paying attention to. Second, weight transparency: in a aisle full of proprietary blends, a label that tells you the actual amounts (Jocko) or at least a real CFU count is doing something most of its competitors won't — reward it. Pick the one whose honesty and certifications you trust, drink it consistently, and treat it as the supplement it is.

Adults Meeting Fruit and Vegetable Intake Recommendations — United States, 2019
Using 2019 national survey data, only 10.0% of US adults met the vegetable intake recommendation (and 12.3% met the fruit recommendation). This is the epidemiological backdrop for greens powders as veggie-gap insurance — and the honest frame that they supplement, rather than replace, the vegetables most adults still aren't eating.

The effects of AG1 supplementation on the gut microbiome of healthy adults: a randomized, double-blind, placebo-controlled clinical trial
In 30 healthy adults over 4 weeks, AG1 enriched two probiotic taxa (Lactobacillus acidophilus and Bifidobacterium bifidum) and was well tolerated with no adverse changes in bowel frequency or stool consistency. The only product-specific RCT in this lineup — an industry-funded microbiome and tolerability study, not a hard-outcome efficacy trial, which is exactly how it should be read.
- [3]Chapple 2012
Adjunctive daily supplementation with encapsulated fruit, vegetable and berry juice powder concentrates and clinical periodontal outcomes: a double-blind RCT
A double-blind RCT in which encapsulated fruit, vegetable and berry juice powder concentrates raised plasma micronutrient markers (including β-carotene) and improved a periodontal treatment outcome. Evidence that concentrated juice powders can measurably move micronutrient biomarkers — though this is a purer juice-concentrate product class than a multi-ingredient greens scoop.
- [4]De Spirt 2012
An encapsulated fruit and vegetable juice concentrate increases skin microcirculation in healthy women
Over 12 weeks in healthy women, an encapsulated fruit and vegetable juice concentrate increased skin microcirculation (by ~39%), hydration and density versus placebo. A concentrated-juice-powder RCT with a real physiological endpoint — supportive of the 'concentrated produce does measurable things' premise, in a related but distinct product class.

The Effect of Spirulina Supplementation on Blood Pressure in Adults: A GRADE-Assessed Systematic Review and Meta-Analysis of Randomized Clinical Trials
A GRADE-assessed meta-analysis of randomized trials found spirulina supplementation lowered systolic blood pressure by ~4.4 mmHg and diastolic by ~2.8 mmHg. Per-ingredient evidence for spirulina, a near-universal greens-powder algae — but trials typically dosed grams of spirulina, far above the amount in a multi-ingredient scoop.
- [6]Fallah 2018
Effect of Chlorella supplementation on cardiovascular risk factors: A meta-analysis of randomized controlled trials
A meta-analysis of 19 randomized trials (797 subjects) found chlorella supplementation significantly reduced total cholesterol, LDL cholesterol, systolic and diastolic blood pressure, and fasting blood glucose. Per-ingredient evidence for chlorella, another common greens-powder algae — again typically at gram-level doses larger than a blended scoop provides.
