Last updated: 3 November 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 CKI612207, issued 11 August 2026: Salmonella and Listeria absent in 25 g; Enterobacteriaceae <10 cfu/g; within FSSR 2011 limits, as the report records. Heavy metals, batch CKI064107, issued 30 December 2025: lead below 0.05 mg/kg and arsenic 0.42 mg/kg (limit 1.1); within FSSR 2011 limits, as the report records. The reports on this page do not measure L-theanine 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 L-Theanine 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.
Latest batch: CKI0318501, heavy metals
Sample described as L-Theanine · Batch CKI0318501 · Avon Food Lab (Pvt.) Ltd. (NABL TC-11151) · Report AFLPL/261012029 · ULR TC1115126000023575F · Received 12 October 2026, issued 19 October 2026.
| Parameter | Result | Limit printed on report |
|---|---|---|
| Arsenic | BQL (LOQ 0.05 mg/kg) | 1.1 mg/kg max |
| Copper | 0.13 mg/kg | 30.0 mg/kg max |
| Cadmium | BQL (LOQ 0.05 mg/kg) | 1.5 mg/kg max |
| Tin | BQL (LOQ 0.3 mg/kg) | 250 mg/kg max |
| Mercury | BQL (LOQ 0.05 mg/kg) | 1.0 mg/kg max |
| Methyl mercury | BQL (LOQ 0.1 mg/kg) | 0.25 mg/kg max |
| Lead | BQL (LOQ 0.05 mg/kg) | 2.5 mg/kg max |
Copper was quantified at 0.13 mg/kg, below the limit printed on the report; the other six parameters were below the method's quantitation limit. BQL means below the method's quantitation limit, not necessarily absent. The lab's remark states the sample conforms to FSSR 2011 for the limits specified. These results apply to batch CKI0318501.

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.
- The reports on this page do not measure L-theanine content, so they do not verify the amounts stated on the label.
- The December 2025 heavy-metals report (batch CKI064107) is page 1 of 2; its page 2 (the signature page) is not published here. All its results are on page 1.
- Passing the listed contaminant tests does not establish absence of every contaminant or suitability for every individual.
