Independent Laboratory Testing
Every batch of Cold Sore Guard™ is independently tested to ensure it meets quality, safety, and label accuracy standards.
We work with accredited laboratories to verify key active ingredients and screen for common contaminants before products are released for sale.
Ingredient Verification (Label Accuracy)
Our supplements are tested to confirm that the active ingredients listed on the label are present and within acceptable tolerances.
Independent analysis verifies key nutrients such as L-Lysine, Vitamin C, and Vitamin B12 to ensure formulation accuracy and consistency from batch to batch.
Heavy Metals Screening
Each batch is screened for common heavy metals, including lead, arsenic, cadmium, and mercury.
Testing confirms levels fall within recognised safety limits and comply with UK and EU supplement regulations.
Microbiological Safety Testing
Products are tested for microbiological safety to ensure they are free from harmful bacteria, yeasts, and moulds.
This helps protect product integrity and consumer safety throughout shelf life.
The Laboratories We Use
All testing is conducted by independent, UK-accredited laboratories, including Reading Scientific Services Ltd (RSSL) and Eurofins.
These laboratories operate under recognised quality systems and are widely trusted within the food supplement industry.
Batch-Specific Testing
Laboratory testing is performed on specific production batches.
Results apply to the samples tested and form part of our internal quality assurance process before products are approved for sale.
Transparency & Consumer Trust
We believe transparency matters. While full laboratory reports are not published publicly, testing is conducted as part of our commitment to product integrity, regulatory compliance, and consumer confidence.
