94% of Vietnamese women see prenatal supplements as beneficial but doubtful of safety


Only 25 per cent of them perceived prenatal supplements as “moderately to completely safe”.

This is according to a study funded by Bayer which looked at how women across Vietnam, Australia, and China perceive the benefits and safety of prenatal supplements.

A total of 1,524 women took part in the online study which specifically collected responses from women who were either preparing to conceive in the next 12 months or were already pregnant. 

The study was conducted between 2021 and 2022, with market research firms IQVIA and fiftyfive5 collecting the data. Findings were published on Frontiers in Global Women’s Health.

Results showed that respondents from China and Australia have a more “balanced” view of the benefits of supplements and its safety.

About four in five (82 per cent) of the Chinese respondents rated pre-natal supplements as being “moderately to highly beneficial”, and 77 per cent rated supplements as “moderately to completely safe”.

While in Australia, 63 per cent and 60 per cent rated prenatal supplements as “moderately to highly beneficial” and “moderately to completely safe” respectively.

The study also looked at the actual number of respondents who took prenatal supplements, their views on the benefits of supplementation on their wellbeing and that of their babies, as well as their trusted source of pregnancy-related knowledge.

Perceived benefits

Across the three countries, the respondents tend to perceive supplementation as being more beneficial when taken during pregnancy than when preparing for pregnancy.
