What a Certificate of Analysis shows
Each Certificate of Analysis is issued for a specific production lot and records the identity, potency and purity testing performed on that batch, including heavy metals and microbial limits where applicable. Mt. Angel Vitamins products are manufactured by Highland Laboratories in Mt. Angel, Oregon, in a GMP-certified facility, and every lot is tested before release.
Matching a certificate to the bottle in your hand is straightforward: find the lot number printed on the label and open the corresponding report above. If a lot is missing from this page, the report exists — request it and we will publish it.
