I have also noticed this. For years I have bought the Centrum nutritional supplement pills in Hong Kong rather than Bangkok because the iron content of those sold here is about a quarter of those purchased in Hong Kong. On my last HK visit a couple of weeks ago,though, I noticed that Centrum has now reduced the iron content of those supplements by two thirds to 9 mgs. Also for the tablets aimed at the over-50s, the content is now 3.6 mgs.
The pharmacist claimed that 27 kgs had been found to create some intestinal or similar problems in Chinese. Hence the reduction. Go figure!
