B12 production companies

At the end of the 'Production' subsection, we have this line:

"The total world production of vitamin B₁₂, by four companies (the French Sanofi-Aventis and three Chinese companies) in 2008 was 35 tonnes."

Is there a reason why only the French company is mentioned and not the three Chinese companies? I think all four companies should be mentioned, else the whole of the brackets should be removed. The cited article is paywalled, so I'm unsure if the original source mentions all four companies. WikidKev (talk) 23:06, 10 January 2024 (UTC)[reply]

Cyanocobalamin sources include sewage sludge.

The cheapest sources of cyanocobalamin come from human sewage treatment plants where they take the sludge & turn it into a powder for energy drink companies. 2600:1700:9461:2020:6961:F9A0:93BF:28AD (talk) 16:08, 14 April 2024 (UTC)[reply]
