Label snapshot
What the product contains and what one serving costs, according to our catalog. Label amounts are not personal dose recommendations.
| Ingredient | Amount per serving |
|---|---|

| Adaptogen blend | 1,300 mg |
| Probiotics | 500 mg |
| Vitamin C | 420 mg |
Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Tested by independent lab.
Read the evidence (3 studies)Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.
This AG1 (Athletic Greens) AG1 Foundational Nutrition scores 6.0, making it below the site average. It delivers 420mg of Vitamin C, inside the studied range of 200–1000mg with grade A evidence (strong human trial data).
The science behind each active ingredient, independent of which brand sells it.
Dried vegetable, algae and grass concentrates in one serving. Nutritious, but trial evidence for health outcomes is nearly empty.
Proprietary stress-herb mixes. The ingredients often have individual trials; the blend as sold almost never does.
Strain-specific benefits; forget 'total CFU' marketing.
Correcting deficiency is important; megadoses rarely add benefit.
Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.
| Ingredient | Dose / serving | Research dose | % of research | Evidence grade |
|---|---|---|---|---|
| Greens blend | 4000 mg | not established | n/a | D |
| Adaptogen blend | 1300 mg | not established | n/a | D |
| Probiotics | 500 mg | not established | n/a | B |
| Vitamin C | 420 mg | 500 mg | 84% | A |
Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →

A methodical teardown concluding AG1 is a reasonably well-formulated multivitamin-plus-greens product but not a whole-food replacement, with real gaps (no Vitamin D, no iron, low fiber) and a meaningful price premium (~$50-70/month above cheaper greens-powder competitors) that isn't clearly justified by ingredient count.
Found detectable but (per FDA interim reference doses) sub-threshold lead contamination; flagged that the level exceeds California's stricter Prop 65 safe-harbor threshold, which led AG1 to add a warning label on California-sold product.
A detailed, credential-backed critique concluding AG1 is overpriced for what it delivers, critiques the La Monica 2024 study's use of maltodextrin as an imperfect placebo, and states plainly: 'I wouldn't spend my money on it. I never have.'
A more measured take than some critics: doesn't call AG1 'wrong' to take, but frames it plainly as a flavored powdered multivitamin, not a substitute for whole vegetables/fiber.
A skeptical academic science-communication critique covering both the Huberman conflict-of-interest and dosing/formulation concerns, plus adverse-event reporting to the FDA.
Quotes British Dietetic Association dietitian Nichola Ludlam-Raine stating greens powders (category-wide, including AG1) do not count toward five-a-day and whole foods remain the first choice.
Best single source detailing founder Chris Ashenden's 2011 New Zealand criminal fraud conviction, his July 2024 resignation as CEO, and critical quotes from Bryan Johnson and Rhonda Patrick.
Documents Huberman's undisclosed-in-detail financial relationships with AG1 and other brands, and flags AG1's excess vitamin dosing as scientifically unnecessary.
Scientific critique of Huberman's sponsor-driven health advice pattern, using AG1 as a central example of sponsor influence outweighing evidence quality.
Credentialed commentary from clinicians who disclose no paid relationship. Useful as supporting critique but not a substitute for a clinical outcome trial.
A generally positive but not exceptional independent customer-rating aggregate, well below AG1's own self-reported '50,000+ 5-star reviews' claim.
Consistent, recurring community consensus across multiple subreddits: AG1 is repeatedly described as an 'extremely expensive multivitamin,' with specific concern that consumers may reduce actual vegetable intake believing AG1 'covers their bases.'

We list this openly. If a claim isn't backed by a source we can trace, we'd rather flag it than repeat it.
Blends without listed amounts hide individual dosages. Popular but scores low on transparency.
