Who published these records

Eight public sources; 5 name a magnesium bottle. Choosing one opens its page, filtered to magnesium.

What is not here

ConsumerLab is not one of the sources: its reviews are paywalled, and nothing on this page is estimated from ConsumerLab. Anresco, InvaPharm, Eurofins appear as the laboratory on a Labdoor certificate, not as a publisher.
