Last updated: 31 October 2026. Added an at-a-glance summary of the results. Results transcribed into text from the original certificates, which are reproduced in full below and remain unchanged.
At a glance: Four reports below, from Avon Food Lab (NABL TC-11151). Microbiology, batch RTM00028606, issued 14 August 2026: Salmonella and Listeria absent in 25 g; Enterobacteriaceae <10 cfu/g; within FSSR 2011 limits, as the report records. Heavy metals, batch RTM240720405H00023702, issued 29 March 2025: lead and arsenic below the quantitation limit (0.05 mg/kg); within FSSR 2011 limits, as the report records. The reports on this page do not measure N-acetyl L-cysteine content, so they do not verify the amounts stated on the label.
These third-party reports record microbiological and heavy-metal results for samples of HealthyHey N-Acetyl L-Cysteine (NAC) submitted by HealthyHey Foods LLP. Read each with its sample description, batch number, methods and limits. A laboratory report is evidence of the tests performed, not certification of every claim on the label.

Scope and limitations
- The laboratory tested samples submitted by HealthyHey; it did not draw them from retail stock.
- The reports cover different batches and dates; each result applies to its own batch.
