The Verdict
AG1 wins on certification, Amazing Grass wins decisively on value, and the price gap is enormous. AG1 carries NSF Certified for Sport (its real differentiator) and scores A on quality, but costs $2.63 per serving. Amazing Grass costs just $0.83 per serving - roughly a third of AG1's price - and carries USDA Organic and Non-GMO Project Verified certification, though no banned-substance testing. Both bury their ingredients in proprietary blends, so neither lets you verify a single dose. The verdict: unless you are a tested athlete who specifically needs the NSF seal, Amazing Grass delivers the same kind of unverifiable greens formula, plus organic certification, at a third of AG1's cost. Paying triple for AG1 only makes sense for the narrow group who use its sport certification - everyone else is paying for marketing.

Why This Comparison Matters
This is the premium-vs-budget greens powder matchup. AG1 is the expensive subscription greens that defined the category through podcast advertising. Amazing Grass is the long-running drugstore-shelf staple that sells for a fraction of the price. The gap between them is roughly three to one per serving, so the real question is whether AG1 gives you three times the product.
Both share the same fundamental limitation: they hide their ingredients in proprietary blends, so you cannot verify the dose of any individual constituent in either one. Amazing Grass at least carries USDA Organic certification; AG1's edge is its NSF Certified for Sport seal. Beyond those two seals, you are comparing two unverifiable formulas at very different prices.
We scored both on clinical evidence, quality testing, cost per serving, and transparency.
Detailed Score Breakdown
AG1 (30 Servings)
AG1 (Athletic Greens)
75+ ingredients organized into proprietary blends - individual ingredient doses are not disclosed, so it is mathematically impossible to verify whether any single ingredient (ashwagandha, rhodiola, milk thistle, etc.) hits its evidence-supported dose
NSF Certified for Sport - the only major greens powder with this certification; tested annually against 280+ banned substances and screened for heavy metals, microbial contamination, and label-claim accuracy
$2.63 per serving on subscription ($79/month) or $3.30 on one-time order - the most expensive product in the category by a wide margin
Discloses NSF Sport status and publishes a certificate of analysis, but the underlying formula is grouped into named blends ('Alkaline, Nutrient-Dense Raw Superfood Complex,' 'Nutrient-Dense Extracts, Herbs and Antioxidants') that hide individual doses
Only NSF Certified for Sport greens powder on the market - genuine differentiator for tested athletes. Premium price reflects the certification more than the formula transparency.
Greens Blend Superfood (Original, 30 Servings)
Amazing Grass
Greens blend plus prebiotics, probiotics, digestive enzymes, and antioxidants - all within proprietary blends with no individual ingredient amounts disclosed
USDA Organic, Non-GMO Project Verified; manufactured in GMP-certified facility; no NSF/USP/Informed Sport certification
$0.83 per serving - excellent value, one of the cheapest entries in the category
USDA Organic certification disclosed but ingredients grouped into 'Greens Blend,' 'Antioxidant Blend,' 'Digestive Enzyme & Probiotic Blend' with only blend totals listed
Long-time category staple at the lowest serving cost reviewed. USDA Organic certification is meaningful, but proprietary blends prevent any verification of ingredient dosing.
How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.

Frequently Asked Questions
Is AG1 worth three times the price of Amazing Grass?
Only if you need the NSF Certified for Sport seal. That certification - which screens for banned substances and verifies label accuracy - is AG1's genuine and unique advantage, and Amazing Grass does not have it. But on the actual formula, both products hide their ingredients in proprietary blends, so neither is more verifiable than the other. At $2.63 per serving versus $0.83, AG1 costs roughly triple. For a general wellness buyer, that premium is hard to justify; for a tested athlete, the seal is the deciding factor.
Is Amazing Grass organic?
Yes. Amazing Grass Greens Blend carries USDA Organic certification and is Non-GMO Project Verified. That is a meaningful quality signal, though it does not address ingredient dosing - the formula is still organized into proprietary blends, so you see the blend totals rather than individual ingredient amounts.
How much does Amazing Grass cost compared to AG1?
Amazing Grass is about $0.83 per serving - one of the cheapest greens powders we track - versus AG1 at $2.63 per serving on subscription. That is roughly a third of the price. Over a year of daily use, Amazing Grass runs around $300 versus roughly $960 for AG1.
Does AG1 have better ingredients than Amazing Grass?
AG1 has a longer ingredient list (75+ versus Amazing Grass's blend), but 'more ingredients' does not mean 'more effective,' especially when both hide their doses in proprietary blends. You cannot verify whether either product's individual ingredients reach evidence-supported amounts. AG1's real advantage is the NSF Certified for Sport seal, not a demonstrably superior formula.
Which greens powder is the better value?
Amazing Grass, by a wide margin, for most buyers. At $0.83 per serving with USDA Organic certification, it delivers the same category of unverifiable greens formula as AG1 at a third of the cost. AG1 only becomes the better value for the specific buyer who needs NSF Certified for Sport - otherwise you are paying a large premium for marketing and a certification you will not use.
