Both AG1 Next Gen and Bloom Greens & Superfoods are greens powders with wide name recognition, strong social proof, and formulas built around the same general promise: a broad-spectrum blend of greens, adaptogens, probiotics, and digestive enzymes in a single daily scoop. But the decision between them does not turn on which has better ingredients — it turns on whether you are paying for verified quality or accessible convenience, and whether either product actually delivers what its label implies.

The honest answer, supported by the evaluations behind this comparison, is that both products have meaningful problems. The question is which set of problems matters more for your situation.

Transparency: Both Hide Doses, But One Hides More

Neither product offers full ingredient-level transparency, and that matters for any greens powder making claims about adaptogens, probiotics, and functional botanicals.

AG1 Next Gen organizes its 83 ingredients into proprietary blends. The largest — a 7,388mg superfood complex and a 2,732mg plant extract complex — disclose only total blend weights, not individual ingredient amounts. Analysis of the extract complex found that fitting clinically studied doses of ashwagandha, rhodiola, and eleuthero simultaneously into 2,732mg alongside ten or more other ingredients is mathematically impossible, meaning at least some of those adaptogens are present at sub-clinical amounts. The brand has not published data demonstrating otherwise.

Bloom Greens & Superfoods has the same structural problem, compounded by a smaller total formula. Its Adaptogenic Herb Blend totals just 100mg across six herbs — ashwagandha, rhodiola, ginseng, licorice, astragalus, and eleuthero among them. No individual ingredient in that blend could reach a clinically studied dose. The probiotic and digestive enzyme blend amounts are not disclosed at all, making it impossible to assess whether those components are present in any meaningful quantity. The Green Superfood Blend at 1,367mg spread across five ingredients leaves each well below the ranges examined in clinical research on individual greens like chlorella.

On this axis, the two products are structurally equivalent in their opacity — but Bloom's smaller total blend sizes make the underdosing concern more acute.

Third-Party Verification: A Real and Consequential Gap

This is where the products diverge most clearly, and where the evaluation evidence is least ambiguous.

AG1 Next Gen holds NSF Certified for Sport status. That certification involves independent batch testing for banned substances and contaminant screening. It does not verify that every ingredient is dosed at a clinically effective level — the formula's proprietary blend structure means that question remains open — but it does provide independent confirmation that what is on the label is in the product, and that the product has been screened for a defined set of contaminants. For a greens powder containing spirulina, chlorella, and multiple botanical extracts, that is a meaningful assurance.

Bloom Greens & Superfoods carries no equivalent certification. The brand states that products are manufactured in GMP-certified facilities and claims rigorous testing, but no NSF, Informed Sport, USP, or Clean Label Project certification is disclosed. This matters specifically because spirulina — a primary ingredient in Bloom's formula — carries documented heavy-metal accumulation risk, and independent testing of greens powders broadly has found that a majority of mixed greens brands exceed heavy-metal thresholds without disclosing it. Without third-party verification, there is no independent basis for assessing Bloom's contaminant profile.

AG1's certification history is not without complication: a 2022 ConsumerLab review of the prior AG1 formula raised concerns about lead and heavy metals, and a pending civil lawsuit alleges cadmium and arsenic detection in independent testing, which the company disputes. AG1 Next Gen is a reformulated product launched after that 2022 test, and the NSF certification provides ongoing batch-level screening. That litigation context is worth knowing, but the independent certification infrastructure AG1 maintains is meaningfully stronger than Bloom's self-reported testing claims.

What the Clinical Evidence Actually Shows

AG1 has one clinical study to its name: a trial showing that the product significantly increased blood levels of folate, calcium, zinc, vitamin C, biotin, and B vitamins compared to a maltodextrin placebo. That is a real finding, and it is the strongest piece of product-level evidence in either evaluation. It demonstrates that the micronutrient component of AG1 is bioavailable and absorbed. It does not demonstrate that the adaptogenic, probiotic, or superfood blend components are effective — those were not the study's endpoints, and the formula's proprietary blend structure means their doses remain unverified.

Bloom Greens & Superfoods has no independent clinical study on the combined formula. Customer testimonials on the brand's site and Amazon describe satisfaction with taste and, in some cases, digestive changes — but the evaluations classify these as anecdotal, not clinical evidence. No independent efficacy data on the combined formula exists.

On this axis, AG1 holds a narrow but real advantage: one study showing micronutrient absorption is more than Bloom has.

Price and Value: Cheap Isn't the Same as Good Value

AG1 Next Gen costs approximately $3.30 per serving at one-time purchase pricing, or around $2.63 per serving on subscription. Bloom Greens & Superfoods costs $1.17 per serving, dropping to roughly $1.05 on subscription.

The price gap is real. But value is not the same as price. The evaluation of AG1 found that most of its 75-plus ingredients appear at doses well below those used in clinical research — sometimes by a factor of ten to one hundred — and that the two ingredients with the strongest evidence at their dosed amounts (a probiotic strain and a bioavailability enhancer) are available separately for a fraction of the cost. The NSF certification justifies some premium, but the evaluation concluded that the premium is not fully supported by the formula's demonstrated efficacy.

Bloom's lower price reflects its position in the non-certified, commodity-tier greens segment. It is affordable, but the absence of third-party verification and the near-certain underdosing of its adaptogenic and probiotic components mean the lower price does not represent meaningfully better value per verified unit of quality.

Neither product scores well on value. AG1 is expensive for what the formula can be confirmed to deliver. Bloom is inexpensive, but without certification, what it delivers cannot be independently confirmed.

Taste and Daily Use: Roughly Equivalent Problems

Both products have documented taste and texture polarization. AG1's newer Citrus and Berry flavors have been described by editorial testers as more artificial-tasting, with a lingering aftertaste, and grittiness and chalkiness are recurring complaints. An independent lab review ranked AG1 eighteenth out of twenty-three greens powders tested.

Bloom's customer reviews are predominantly positive on taste — "doesn't taste like grass" is a common sentiment — and the brand has built substantial loyalty through social media, particularly on TikTok. However, a recurring minority of reviewers cite a "weird taste" and gritty or chalky texture significant enough to discontinue use even when they reported noticing functional changes.

AG1 offers a ninety-day money-back guarantee, which is a meaningful consumer protection for a product at its price point. Bloom's return policy terms are not detailed in the evaluation corpus to the same degree.

Legal and Regulatory Context

Both brands carry litigation context worth noting without overstating. AG1 faces a pending civil lawsuit alleging heavy-metal contamination, which the company disputes and which has not resulted in regulatory action. Bloom Nutrition faces a class-action lawsuit filed in 2025 alleging false advertising. Neither lawsuit constitutes a finding of wrongdoing, and neither evaluation treats pending litigation as equivalent to a regulatory enforcement action. Both are disclosed here as context.

Who Should Buy AG1 Next Gen

If third-party certification matters to you — and for a greens powder you plan to take daily, it should — AG1 is the only product in this comparison that provides it. The NSF Certified for Sport credential offers independent batch testing that Bloom does not. The clinical study showing micronutrient absorption is real, if limited in scope. If you are an athlete subject to drug testing, AG1's certification is directly relevant. If you are willing to pay a significant premium for independent verification and can accept that the adaptogenic and superfood components of the formula remain unverified for dose efficacy, AG1 is the more defensible choice between these two.

Who Should Buy Bloom Greens & Superfoods

If budget is the primary constraint and you are looking for a broad-spectrum greens powder without strong expectations that the adaptogenic or probiotic components are clinically dosed, Bloom is accessible and widely available. Its taste profile works well for many users, and its community following suggests genuine repeat purchase behavior. But you are accepting the absence of third-party contaminant verification for a product that contains spirulina and chlorella — ingredients with documented heavy-metal risk in the greens category broadly.

Who Should Consider Neither

If your goal is a greens powder where the adaptogenic, probiotic, and superfood components are dosed at levels examined in clinical research and independently verified, neither product delivers that with confidence. Both rely on proprietary blends that obscure individual ingredient amounts, and both contain adaptogens at doses the evaluations identify as likely sub-clinical. The evaluation of AG1 specifically notes that comparable greens products are available at substantially lower price points. If certification is non-negotiable and budget is a concern, the better path may be a simpler, certified multivitamin paired with individually dosed supplements — rather than either of these all-in-one powders.
