Google turned off Shopping functions for vitamins, supplements and other healthcare products on 28 June, without advance warning or explanation.
For example, if you Google “vitamin C” the Web search returns 94.7 million results; if you then click on “Shopping” to find sellers, the shopping search returns zero results.
It’s as though no one’s allowed to sell vitamin C via Google Shopping. Even “Bayer aspirin” is blocked.
