Consumer Reports testing found lead levels exceeding safe daily thresholds. Plant-based pea/rice blends consistently showed higher heavy metal concentrations than dairy-based alternatives.

Multiple independent tests flagged elevated heavy metal levels. Garden of Life products have been named in class action litigation over undisclosed contaminant levels.

ConsumerLab found the protein content did not match the amount stated on the label, raising false advertising concerns under NY GBL §§ 349 and 350.

Testing detected lead and arsenic above recommended daily exposure thresholds for regular use. Rice protein formulations showed particularly elevated arsenic levels.

ConsumerLab noted AG1's multi-ingredient plant composition creates meaningful potential for lead accumulation per serving, particularly at the daily serving amounts the company recommends.

Flagged for both elevated lead levels and failure of dissolution testing — meaning ingredients may not be absorbed as implied even if present at stated amounts.

ConsumerLab found multiple turmeric/curcumin supplements contained significantly less curcuminoid content than stated, with some containing less than 50% of what was claimed.

Many products claiming standardized extracts (e.g., KSM-66) contained significantly less than labeled amounts of active withanolides — the compounds that drive the claimed benefits.

Multiple Ayurvedic supplements carry California Prop 65 warnings for lead and mercury. FDA enforcement data consistently shows this category has the highest heavy metal contamination rates of any supplement type.

ConsumerLab flagged heavy metal concerns. Prenatal lead exposure is particularly serious: even low-level exposure during pregnancy is associated with fetal neurological harm, low birth weight, and developmental delay.

The "whole food" sourcing approach used in this product line has been associated with elevated heavy metal levels. Any lead in a prenatal supplement is especially concerning given fetal vulnerability.

ConsumerLab testing found potency variance on several vitamins — the amount of certain ingredients did not match label claims within acceptable tolerance, raising false advertising concerns.

Several collagen powder products did not contain the amount of collagen peptides stated on the label, or failed nitrogen testing used to assess protein content.

One of the most consistently problematic categories in ConsumerLab testing — multiple products found to contain dramatically less glucosamine or chondroitin than labeled, sometimes less than 10% of the claimed amount.
