AG1 is the product every other greens powder gets measured against, and it earns that status: an NSF-certified scoop that bundles a multivitamin, a disclosed 7.2 billion CFU probiotic and 75+ vitamins, minerals and superfoods into one daily drink. It's also the only product in our nine-strong lineup with its own published clinical trial — a 4-week microbiome and tolerability study — which puts it a tier above competitors on independent scrutiny. The reasons it lands at #2 rather than #1 are price and disclosure. At $74 on Amazon, $79 on subscription, or $99 one-time DTC, it's the most expensive pick here by a wide margin — roughly $2.47 to $3.30 a serving. And while it discloses more than most (its CFU count and mushroom complex are stated), its core superfood complexes are still listed at blend level, where Jocko Fuel (#1) states every ingredient amount. AG1 is the best-tested, most convenient all-in-one in the category; whether it's worth two to three times the price of a credible cheaper greens depends entirely on how much you value the NSF certification and the one-scoop convenience.

Read the complete Greens Powder guide →More transparent than most of the category — AG1 discloses its 7.2 billion CFU two-strain probiotic and a 154 mg mushroom complex and lists 75+ ingredients. Held below the leader because its core superfood complexes are still disclosed at blend level, not per individual ingredient, where Jocko Fuel (#1) states every amount. Strong, but not best-in-class on pure disclosure.
The broadest, most complete active load here: 75+ vitamins, minerals and superfoods functioning as a multivitamin, plus a disclosed 7.2 billion CFU probiotic. It genuinely covers multivitamin and probiotic duty in one scoop — the most substantive all-in-one formula in the lineup. Near-perfect; the only product that rivals its breadth is Huel.
The category's strongest trust signal. NSF International certification (the listing states testing at 95× the industry standard, free of banned substances) means independent verification of contents and contaminant screening — exactly what matters in a category where a contaminated supply chain caused a 2026 Salmonella recall elsewhere. Top of the lineup on testing, and a key reason it ranks this high despite the price.
The weakest axis. At $74 Amazon / $79 subscription / $99 one-time DTC, it's roughly $2.47–$3.30 per serving — the most expensive pick here, two to three times most competitors. The score isn't lower only because the price buys a genuine all-in-one (multivitamin + probiotic + greens) plus NSF certification; as a pure cost-per-serving proposition it loses badly to Huel and Amazing Grass.
The pineapple-vanilla flavor is widely rated as mild and easy to drink, it's vegan and keto-friendly with under 1g of sugar, and it mixes cleanly with the included shaker. One of the more reliably palatable greens powders for daily compliance — a genuine strength that helps justify the habit at the price.
“NSF certified and tested at 95× the industry standard.”
NSF International certification is stated on the listing and is the strongest independent-testing claim in our nine-product lineup. It verifies contents and screens for banned substances — a genuine, auditable differentiator, and the main driver of AG1's perfect testing score.
“One scoop replaces your multivitamin, probiotic and greens.”
Reasonable for the multivitamin and probiotic roles — AG1 is built around 75+ vitamins and minerals plus a disclosed 7.2 billion CFU probiotic. But 'replaces your greens' overstates it: like all greens powders it lacks the fiber, food matrix and satiety of whole vegetables. A capable all-in-one supplement, not a food replacement.
“75+ vitamins, minerals and whole-food sourced ingredients.”
The 75+ ingredient count is stated on the listing and is consistent with AG1's all-in-one positioning; it's among the broadest formulas in the category. Note that breadth is disclosed partly at blend level, so the count is verifiable but the individual amounts within the core complexes are not fully itemized.
“Clinically studied for the gut microbiome.”
Supported by La Monica 2024 (PMID 39352252): a 4-week randomized, double-blind, placebo-controlled trial found AG1 enriched two probiotic taxa with no adverse bowel changes. Accurate as stated — a real microbiome and tolerability RCT — provided it's not over-read as proof of broad health-outcome efficacy.
“Supports energy, immunity and whole-body health.”
Plausible at the ingredient level — AG1 supplies B-vitamins, vitamin C, zinc and other nutrients with established roles in energy metabolism and immune function — but the product's own trial measured the microbiome and tolerability, not energy or immunity endpoints. Mechanistically reasonable, not directly demonstrated for AG1 itself.
La Monica 2024 (PMID 39352252) puts AG1 in a category of one within our lineup: a 4-week, randomized, double-blind, placebo-controlled study in 30 adults that found AG1 enriched Lactobacillus acidophilus and Bifidobacterium bifidum and was well tolerated, with no adverse changes in bowel frequency or stool consistency. It's industry-funded and it's a microbiome/tolerability study rather than a hard-outcome efficacy trial — but it's real evidence the product does something measurable, which is more than any competitor here can show.
AG1's perfect testing score rests on NSF International certification — independent verification of contents plus banned-substance screening, stated at 95× the industry standard. In a category where a contaminated moringa supply chain caused a multi-state Salmonella outbreak elsewhere in 2026, that independent verification is worth real money. It's the single strongest reason a buyer who weights safety heavily might choose AG1 over a cheaper, self-disclosed competitor.
With 75+ ingredients functioning as a multivitamin plus a disclosed 7.2 billion CFU probiotic, AG1 is the most complete all-in-one here. The asterisk is disclosure: it states its CFU and mushroom complex but lists core superfood complexes at blend level, so you can't itemize every amount the way you can with Jocko Fuel (#1). It's more transparent than a pure proprietary-blend product, less so than the per-ingredient leader.
Everything about AG1 is strong except the cost: up to $3.30 a serving, two to three times most competitors, on a subscription-first DTC model where one-time buyers pay the steepest premium. If AG1 genuinely replaces a separate multivitamin and probiotic in your routine, the value gap narrows. If you only want greens, Huel (#3) offers comparable breadth at roughly half the price and Amazing Grass (#7) covers the core job for about $0.90 a serving. The certification and convenience are real — you just pay a lot for them.
AG1 is the reference product for good reasons: NSF-certified, built around 75+ ingredients that cover multivitamin and probiotic duty, and the only greens powder in our lineup with its own published trial. On testing and all-in-one completeness, nothing here beats it. If you want the most-scrutinized scoop and you'll treat price as secondary — or if it genuinely replaces a separate multivitamin and probiotic — it's an easy recommendation. It lands at #2 because of cost and disclosure. At up to $3.30 a serving it's the priciest pick here by a wide margin, and its core blends are still disclosed at blend level where Jocko Fuel (#1) itemizes every amount. Read its trial honestly, too: it's a 4-week microbiome and tolerability study, not proof a scoop replaces vegetables or fixes energy and immunity. For the buyer who values NSF certification and one-scoop convenience above all, AG1 is the pick. For the buyer who wants the same job done cheaper, the rest of this ranking has better-value answers.

Only 10.0% of US adults met the vegetable recommendation in 2019. The gap AG1 hedges against — while remaining a supplement to vegetables, not a replacement for the fiber and food matrix whole produce provides.
Encapsulated fruit/vegetable/berry juice powders raised plasma micronutrient markers (including β-carotene) in a double-blind RCT. Supportive that concentrated produce powders can move micronutrient biomarkers — context for AG1's multivitamin-coverage positioning, in a related juice-concentrate product class.
