The main Amazing Grass lawsuit on record is a 2019 California enforcement action that ended in a $213,167 settlement over lead and cadmium in thirteen of the company’s products. Since then, private parties have filed at least three more Proposition 65 notices against the brand, and in May 2026 a law firm opened a separate investigation into how the company handles subscription billing.
The 2019 California Attorney General Settlement
On September 20, 2019, then-Attorney General Xavier Becerra announced a settlement with Grass Advantage, the company operating under the Amazing Grass name. The state alleged the company had sold thirteen products containing excessive lead or cadmium without the warnings Proposition 65 requires, and had also violated California’s False Advertising Law and Unfair Competition Law.1California Office of the Attorney General.

The flagged products ran across the company’s lineup: meal replacement powders, nutrition bars, and superfood blends.
- Amazing Meal Chocolate Infusion
- Amazing Grass Raw Reserve Chocolate
- Amazing Meal Pomegranate Mango Infusion
- Amazing Grass Green Superfood Whole Food Nutrition Bars (Café Mocha, Lemon Coconut, Chocolate, and Chocolate Chip Coconut)
- Amazing Grass Green Superfood Alkalize & Detox
- Amazing Grass Green Superfood Tangerine Immunity Defense
- Amazing Grass Organic Wheat Grass
- Amazing Grass Green Superfood Pineapple Multivitamin Lemongrass
- Amazing Grass Green Superfood Watermelon Energy
- Amazing Grass Green Superfood Acai-Berry Antioxidant ORAC
Amazing Grass paid $213,167 in penalties and discontinued sales of seven of the thirteen products found to contain high lead levels.2Los Angeles Times. Newport Supplement Company Fined $213,000 for Selling Products With Excessive Levels of Lead and Cadmium
What the Settlement Required Going Forward
The consent judgment did more than collect a fine. Amazing Grass had to retain a food quality auditor to recommend measures for cutting lead in its remaining products, including finding low-lead ingredient sources, implementing lead-specific quality control, and calculating how much of the lead was naturally occurring rather than introduced elsewhere in the supply chain.1California Office of the Attorney General.

The company also had to follow the auditor’s recommendations, place Prop 65 warnings on any product still exceeding state exposure thresholds, run routine testing on covered products, and hand those test results to the Attorney General on request for at least three years.2Los Angeles Times.

Proposition 65 Notices Filed Since 2019
The settlement did not close the door on further complaints. On December 29, 2022, Berj Parseghian, represented by KJT Law Group, filed a sixty-day notice of intent to sue Grass Advantage, Glanbia Performance Nutrition, and Rite Aid Corporation over lead in Amazing Grass Greens Blend Alkalize & Detox, alleging the product had been sold without warnings since at least December 2021.3California Office of the Attorney General.

On April 9, 2025, the nonprofit WHEN Justice, through Soteria Law, filed a notice covering six products. Three of them were marketed to children under the KIDZ Superfood line:4California Office of the Attorney General. Notice of Violation, WHEN Justice v. Glanbia Nutritionals and Grass Advantage
- Amazing Grass Greens Blend KIDZ Superfood Protein and Probiotics Strawberry Blast (lead and cadmium)
- Amazing Grass Greens Blend KIDZ Superfood Blend Berry Blast (lead)
- Amazing Grass KIDZ Superfood Blend Outrageous Chocolate (lead)
- Amazing Grass Greens Blend Superfood Berry (lead)
- Amazing Grass Greens Blend Immunity Elderberry (lead)
- Amazing Grass Greens Blend Immunity Tangerine (lead)
Then on December 12, 2025, Environmental Health Advocates filed a notice against Grass Advantage and Walmart over lead in Amazing Grass Greens Trio.5California Office of the Attorney General. Notice of Violation, Environmental Health Advocates v. Grass Advantage and Walmart
Under California law, a sixty-day notice is a prerequisite before a private party can sue. If a public enforcement agency does not step in within sixty days, the noticing party can proceed on its own. None of the post-2019 notices appear to have produced a publicly reported settlement or judgment in the available research.
The 2026 Subscription Billing Investigation
The heavy metal cases are not the only consumer issue in play. In May 2026, the law firm Migliaccio & Rathod LLP announced an investigation into Amazing Grass over its subscription billing. The firm alleged that customers who chose a discounted purchase option were being enrolled in recurring shipments without clear disclosure, that canceling was difficult, and that shipments continued after customers tried to cancel.6ClassLawDC. Amazing Grass Greens Blend Subscription Billing Investigation As of that announcement, no class action had been filed; the matter was still pre-litigation.
Why Greens Powders Keep Showing Lead
Amazing Grass is not an outlier. A Clean Label Project study of 165 top-selling protein powders found that 47% exceeded at least one federal or state safety standard for toxic metals, and 21% contained more than twice California’s Prop 65 threshold for lead.7Clean Label Project. Protein Powder Study Plant-based products carried about three times more lead than whey-based ones, organic tested higher than non-organic, and chocolate flavors ran roughly four times higher in lead than vanilla.8NutraIngredients. Clean Label Project Releases Controversial Protein Powder Report
Those patterns line up with the Amazing Grass products that have drawn notices: plant-based, often chocolate-flavored, and built around concentrated greens. Heavy metals reach these powders through soil, fertilizers, and pesticides, and they are difficult to remove from ingredients whose whole appeal is being dense and unrefined. That does not excuse a missing warning label, but it explains why the same brand keeps appearing on the same list.
