What do the colors and error bars mean?

The colors carry the original report’s labels, such as “In Spec” and “Caution High.” The source report does not specify the numerical thresholds or how its error bars were calculated. These labels are not a separate safety rating. The chart is reproduced as published; its statistical basis is not specified in the accompanying text. The table shows each laboratory separately.

Methodology

All products were independently purchased either through Amazon or directly from the manufacturer to reflect what consumers would receive in the marketplace. Samples were submitted to two independent ISO 17025–accredited laboratories: Omnient Labs and NJ Labs.
Mineral analysis was performed using Inductively Coupled Plasma–Mass Spectrometry (ICP-MS), a highly sensitive and validated analytical technique widely used for quantitative elemental analysis. Each product was tested in triplicate to ensure reproducibility and analytical reliability.
Samples were not blinded; however, laboratories did not communicate results prior to issuance of final reports, and all data were transmitted directly in formal laboratory documentation. No data manipulation or post-analysis adjustments were made beyond standard quality control verification procedures.

Future Nutra Foundation extends special thanks to Omnient Labs and NJ Labs for their generous contribution and technical support in making this analysis possible.
