Does the marketing hold up?
Registered owner records: Athletic Greens International, Inc. · Athletic Greens TM Holding Limited The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 26 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 2 g of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 15 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
